Rainforest loss increased in the 2000s, concludes new analysis
(02/25/2015) Loss of tropical forests accelerated roughly 60 percent during the 2000s, argues a paper published in the journal Geophysical Research Letters. The findings contradict previous research suggesting that deforestation slowed since the 1990s. The study is based on a map of 1990 forest cover developed last year by Do-Hyung Kim and colleagues from the University of Maryland. The map, which includes 34 countries that contain 80 percent of the world's tropical forests, enabled the researchers to establish a consistent baseline for tracking forest cover change across regions and countries over time.
Suspects acquitted in shocking murder of sea turtle conservationist
(01/27/2015) Yesterday, the seven men accused of brutally murdering Jairo Mora Sandoval on a beach in Costa Rica two years ago were acquitted of the crime. Sandoval's murder shocked the Central American country—long known for the progressive protection of its lush rainforests and sweeping beaches—but the judge who acquitted the accused cited reasonable doubt and a investigation marred by mistakes.
Scientists rediscover Critically Endangered streamside frog in Costa Rica
(12/26/2014) In the past 20 years, amphibian species around the world have experienced rapid decline due to climate change, disease, invasive species, habitat loss and degradation. Populations have decreased by approximately 40 percent with nearly 200 species thought to have gone extinct since 1980. However, despite these discouraging statistics, new research efforts are turning up lost populations of some vanished frogs.
Initiative to restore 50M acres of degraded Latin American ecosystems by 2020
(12/07/2014) A coalition of governments and organizations today pledged to restore 20 million hectares (50 million acres) of degraded forests and ecosystems across Latin America by 2020 under an initiative that aims to curb boost rural incomes, fight climate change, and increase agricultural production. The effort is backed by $365 million from five impact investors.
The 90 Percent Diet: reducing our environmental impact by eating less meat
(08/07/2014) In Brian Machovina’s life, a serendipitous influence of people and places have all contributed to his current passion for inspiring people to eat less meat. With fewer grazing animals, Machovina’s studies show that we could make better conservation and production choices with land that would otherwise be used to raise or feed livestock.
Olinguito, tinkerbell, and a dragon: meet the top 10 new species of 2013
(05/22/2014) Out of around 18,000 new species described and named last year, scientists have highlighted ten in an effort to raise awareness about the imperiled biodiversity around us. Each species—from a teddy-bear-like carnivore in the Andes to a microbe that survives clean rooms where spaceships are built—stands out from the crowd for one reason or another.
The matrix matters: scientists find surprising biodiversity between forests
(05/20/2014) In human-dominated countryside areas, forests are often fragmented and scattered among a matrix of developments such as plantations and pastures. Scientists have long overlooked the habitat value of these matrices. However, according to a recent study published in Nature, the biodiversity of altered countryside areas that exist between islands of fragmented forests can be significant and deserving of conservation attention.
City lights threaten rainforests by deterring bats
(04/09/2014) Fruit-eating bats play an important role in forest regeneration, collecting and spreading seeds far and wide. However, human development may be stymying bat-mediated dispersal. In a new study, researchers found that fruit bats avoid feeding in light-polluted areas, which may significantly affect forest growth.
Sloths, moths and algae: a surprising partnership sheds light on a mystery
(03/22/2014) While it spends the majority of its time in the safety of tree canopies, the three-toed sloth regularly places itself in mortal danger by descending to the forest floor to defecate. For years, scientists have been trying to figure out what is driving this peculiar and risky behavior. Now, Jonathan Pauli from the University of Wisconsin-Madison believes his team of researchers has found an important clue to this mystery involving an unusual and beneficial relationship among sloths, moths and algae.
Leftover trees enhance the biodiversity of new forests
(03/18/2014) Trees left standing after deforestation have a discernible impact on the composition of local biodiversity in secondary growth forests, according to a new study published in PLOS ONE. Researchers working on the Osa Peninsula in Costa Rica discovered that remnant trees could affect species composition of regenerated forests up to 20 years after being logged.
Ecotourism pays: study finds lower poverty where nature-based tourism is prevalent
(02/25/2014) A new study has quantified a point long advocated by advocates of setting aside protected areas: ecotourism pays. The research, published in Proceedings of the National Academy of Sciences (PNAS), finds that communities neighboring conservation areas in Costa Rica had lower rates of poverty relative to other areas.
Bromeliads may actually protect fruit trees from pest damage
(01/22/2014) Imagine a plant. Now remove the soil, for it’s not essential. In fact, an estimated one-tenth of all plant species have liberated themselves from soil and evolved into epiphytes — plants that grow on other plants.
Tree islands more effective way to replant the world's forests
(01/09/2014) Worldwide, large swaths of land lay barren in the wake of agricultural expansion, and as global forest cover continues to decline, carbon and water cycles, biodiversity, and human health are impacted. But efforts to restore abandoned pastures and agricultural plots back into functioning forest ecosystems are often hindered by high costs and time requirements. Fortunately, scientists have developed a new method for a more cost effective solution to forest restoration, the establishment of 'tree islands.'
Top 10 HAPPY environmental stories of 2013
(12/19/2013) China begins to tackle pollution, carbon emissions: As China's environmental crisis worsens, the government has begun to unveil a series of new initiatives to curb record pollution and cut greenhouse emissions. The world's largest consumer of coal, China's growth in emissions is finally slowing and some experts believe the nation's emissions could peak within the decade. If China's emissions begin to fall, so too could the world's.
Camera traps find less mammals than expected in Costa Rican corridor
(12/16/2013) A new study using camera traps in mongabay.com's open-access journal Tropical Conservation Science has surveyed the diversity of medium and large-sized predators in the San Juan-La Selva biological corridor in Costa Rica, whilst also demonstrating how alteration of habitat is affecting the use of this corridor.
Big data shows tropical mammals on the decline
(12/12/2013) The world's largest remote camera trap initiative—monitoring 275 species in 17 protected areas—is getting some big data assistance from Hewlett-Packard (HP). To date, the monitoring program known as the Tropical Ecology Assessment and Monitoring (TEAM) Network has taken over 1.5 million photos of animals in 14 tropical countries, but conservationists have struggled with how to quickly evaluate the flood of data.
Top 10 Environmental Stories of 2013
(12/10/2013) 1. Carbon concentrations hit 400ppm while the IPCC sets global carbon budget: For the first time since our appearance on Earth, carbon concentrations in the atmosphere hit 400 parts per million. The last time concentrations were this high for a sustained period was 4-5 million years ago when temperatures were 10 degrees Celsius higher. Meanwhile, in the slow-moving effort to curb carbon emissions, the Intergovernmental Panel on Climate Change (IPCC) crafted a global carbon budget showing that most of the world's fossil fuel reserves must be left untouched if we are to avoid catastrophic climate change.
Satellites reveal browning mountain forests
(11/22/2013) In a dramatic response to global warming, tropical forests in the high elevation areas of five continents have been "browning" since the 1990s. They have been steadily losing foliage, and showing less photosynthetic activity. Scientists analyzed the forest cover by using satellites to measure sunlight bouncing off the surface of the earth, then determining the different surface types via reflection patterns.
Longline fisheries in Costa Rica hook tens of thousands of sea turtles every year
(11/14/2013) Hundreds of kilometers of commercial fishing lines slither along coastal waters in Costa Rica, hooking thousands of mahi-mahi and many other marketable fish. But when scientists scrutinized fishermen’s catch, they were shocked by the staggering number of sea turtles accidentally snagged on the lines.
Fishermen get crafty to circumvent shark fin ban
(11/10/2013) Authorities in Costa Rica have identified a new method used by fishermen to circumvent a ban on killing sharks for their fins. According to an INTERPOL alert, fishermen are now leaving a band of skin to keep the fin attached to the spine when they kill sharks. This approach takes advantage of an apparent loophole in regulations governing the shark fin trade.
Thought-to-be-extinct 'halloween' frog rediscovered in Costa Rica
(11/04/2013) A breeding population of a critically endangered harlequin toad thought to be extinct in Costa Rica has been discovered in a tract of highland forest in the Central American country, reports a paper published in Amphibia-Reptilia. Atelopus varius, an orange-and-black harlequin toad, was once relatively common from central Costa Rica to western Panama. But beginning in the 1980's the species experienced a rapid population collapse across most of its range.
Nature tours in Costa Rica: an economic alternative to palm oil?
(10/16/2013) Oil palm plantations have been rapidly expanding across the tropics for the better part of the past twenty years due to high returns from palm oil production. But palm oil isn't necessarily the most profitable form of land use in wildlife-rich areas, as one conservation entrepreneur is demonstrating in Costa Rica.David Lando Ramirez, a landowner in Sarapiqui, northeastern Costa Rica, has converted a small patch of oil palm into a thriving ecotourism business centered around people's love of the Central American nation's stunning diversity of birds.
Climate change pushing tropical trees upslope 'exactly as predicted'
(09/27/2013) Tropical tree communities are moving up mountainsides to cooler habitats as temperatures rise, a new study in Global Change Biology has found. By examining the tree species present in ten one-hectare plots at various intervals over a decade, researchers found that the proportion of lowland species increased in the plots at higher elevations. The study, which was undertaken in Volcan Barva, Costa Rica, adds to a growing body of evidence that climate change is having an impact on species range distributions.
Preserving forest, birds boosts coffee profit up to $300/ha by controlling pests
(09/11/2013) Birds are providing a valuable ecosystem service on coffee plantations in Costa Rica, finds a new study that quantifies the pest control benefits of preserving tree cover in agricultural areas. The study, published in the journal Ecology Letters, looked at the impact of the coffee berry borer beetle (Hypothenemus hampeii) on coffee yields. The beetle is the only insect that directly consumes coffee berries, making it a major scourge for coffee farmers around the world, costing producers some $500 million a year.
New tiny insect named after Peter Pan fairy discovered in Central America
(08/16/2013) A new genus of fairyfly has been discovered in Costa Rica. The new species aptly named Tinkerbella nana after the fairy in J.M. Barrie’s play ‘Peter Pan’ is one of the smallest winged insects in the neotropics. Found in both temperate and tropical climates, the fairyfly is not actually a fly as its name suggests, but instead is more closely related to wasps – being classed within the superfamily Chalcidoidea, or the “chalcid wasps”.
Deforestation ban working in Costa Rica
(08/05/2013) Costa Rica's ban on clearing of "mature" forests appears to be effective in encouraging agricultural expansion on non-forest lands, finds a study published today in the journal Environmental Research Letters. The study, which was led by Matthew Fagan of Columbia University, found that since Costa Rica implemented its ban on conversion of mature forests in 1996, the annual rate of old-growth forest loss dropped 40 percent despite an agricultural boom in the region. The results suggest that Costa Rica is intensifying agricultural production while simultaneously sparing forests.
Suspects arrested in Costa Rican sea turtle conservationist's murder
(08/03/2013) Eight suspects were arrested during early-morning raids Wednesday in the murder of Costa Rican sea turtle conservationist Jairo Mora.
Scientists build app to automatically identify species based on their calls
(07/16/2013) New technology makes it possible to automatically identify species by their vocalizations. The platform, detailed in the current issue of the journal PeerJ, has been used at sites in Puerto Rico and Costa Rica to identify frogs, insects, birds, and monkeys. Many of the animals identified by the system are typically difficult to spot in their natural environment, but audio recordings of their calls reveal not only their presence but also their activity patterns.
Conservationists urge Costa Rica to maintain environmental leadership
(06/30/2013) A body representing hundreds of biologists and conservation scientists has urged the government of Costa Rica not to jeopardize its reputation as an environmental leader by allowing carve-outs from protected areas for industrial development. In a declaration issued Thursday at the conclusion its 50th annual meeting, the Association for Tropical Biology and Conservation (ATBC), applauded Costa Rica's pathbreaking efforts to integrate environmental protection into its national development strategy. But the group warned that proposed projects that would require de-gazetting of national parks for energy projects could undermine Costa Rica's green credentials.
Sea Shepherd to name new ship after slain sea turtle activist
(06/28/2013) Marine conservation group Sea Shepherd will name its newest vessel after Jairo Mora Sandoval, a sea turtle conservationist who was slain on a Costa Rican beach last month.
Reward for information on sea turtle conservationist's murder reaches $56,000
(06/13/2013) Conservation organizations and individuals have raised $56,000 for information leading to the arrest and conviction of turtle egg poachers who murdered Jairo Mora Sandoval, a 26-year-old sea turtle conservationist earlier this month.
Costa Rican environmentalist pays ultimate price for his dedication to sea turtles
(06/10/2013) On the evening of May 30th, 26-year-old Jairo Mora Sandoval was murdered on Moin beach near Limón, Costa Rica, the very stretch of sand where he courageously monitored sea turtle nests for years even as risks from poachers rose, including threats at gunpoint. A dedicated conservationist, Sandoval was kidnapped along with four women volunteers (three Americans and one from Spain) while driving along the beach looking for nesting sea turtles. Sandoval was separated from the women—who eventually escaped their captors—but the young Costa Rican was stripped naked, bound, and viciously beaten. Police found him the next day, face-down and handcuffed in the sand; Sandoval died of asphyxiation.
First strike: nearly 200 illegal loggers arrested in massive sting across 12 countries
(02/20/2013) One-hundred-and-ninety-seven illegal loggers across a dozen Central and South American countries have been arrested during INTERPOL's first strike against widespread forestry crime. INTERPOL, or The International Criminal Police Organization, worked with local police forces to take a first crack at illegal logging. In all the effort, known as Operation Lead, resulted in the seizure of 50,000 cubic meters of wood worth around $8 million.
Three developing nations move to ban hunting to protect vanishing wildlife
(01/21/2013) Three developing countries have recently toughened hunting regulations believing the changes will better protect vanishing species. Botswana has announced it will ban trophy hunting on public lands beginning in 2014, while Zambia has recently banned any hunting of leopards or lions, both of which are disappearing across Africa. However, the most stringent ban comes from another continent: Costa Rica—often considered one of the "greenest" countries on Earth—has recently passed a law that bans all sport hunting and trapping both inside and outside protected areas. The controversial new law is considered the toughest in the Western Hemisphere.
Telling the story of the father of sea turtle conservation
(01/21/2013) In 1959, visionary Archer Carr founded the world's first conservation group devoted solely to sea turtles. Working with these marine denizens in Costa Rica, Carr was not only instrumental in changing local views of the turtles—which at the time were being hunted and eaten at unsustainable rates—but also in establishing basic practices for sea turtle conservation today. Now a new film by Two-Head Video, Inc. tells the story of Carr's work and the perils still facing marine turtles today.
Gaming for rainforests
(10/03/2012) The average gamer will spend thousands of hours playing video games by the time they reach adulthood, but the most popular games among some demographics — shoot-em-up and sports games — don't seem to offer many dividends to society or the environment. However Jan Dwire doesn't believe that has to be the case. With a small team in Costa Rica, Dwire has developed "Rainforest Rangers", a multi-platform game that teaches kids about rainforests, including their importance and the threats they face.
Jaguar conservation gets a boost in North and Central America
(09/27/2012) Jaguar conservation has received a huge boost in the past few months both in Latin America and in the U.S. An historic agreement singed between the world's leading wild cat conservation organization Panthera and the government of Costa Rica in addition to a new U.S. Fish and Wildlife Service (FWS) proposal bring renewed hope to the efforts to revive the iconic jaguar in its current habitat and return the cats to the American Southwest.
Dry forests disappearing faster than rainforests in Latin America
(08/21/2012) Countries across Latin America lost 78,000 square kilometers of subtropical and tropical dry broadleaf forests between 2001 and 2010, according to a new satellite-based assessment published in the journal Biotropica.
Animal picture of the day: the boat-billed heron
(05/16/2012) Boat-billed herons (Cochlearius cochlearius) are found in Central and South America, as far north as Mexico and as far south as Argentina. A notably bizarre heron, the species is the only member of the genus Cochlearius. Like many heron species it feeds on a wide variety of freshwater and terrestrial animals.
Jaguar v. sea turtle: when land and marine conservation icons collide
(05/16/2012) At first, an encounter between a jaguar (Panthera onca) and a green sea turtle (Chelonia mydas) seems improbable, even ridiculous, but the two species do come into fatal contact when a female turtle, every two to four years, crawls up a jungle beach to lay her eggs. A hungry jaguar will attack the nesting turtle, killing it with a bite to the neck, and dragging the massive animal—sometime all the way into the jungle—to eat the muscles around the neck and flippers. Despite the surprising nature of such encounters, this behavior, and its impact on populations, has been little studied. Now, a new study in Costa Rica's Tortuguero National Park has documented five years of jaguar attacks on marine turtles—and finds these encounters are not only more common than expected, but on the rise.
Tink frog calls allow researchers to measure population
(03/19/2012) Given their often tiny size and cryptic nature, how does one determine frog populations in the rainforest? Just eavesdrop. A new study in mongabay.com's open access journal Tropical Conservation Society (TCS) employed automated recorders to listen to amphibian calls to determine if the common tink frog (Diasporus diastema) could be found in recovering secondary forests in Costa Rica.
Earth systems disruption: Does 2011 indicate the "new normal" of climate chaos and conflict?
(12/21/2011) The year 2011 has presented the world with a shocking increase in irregular weather and disasters linked to climate change. Just as the 2007 "big melt" of summer arctic sea ice sent scientists and environmentalists scrambling to re-evaluate the severity of climate change, so have recent events forced major revisions and updates in climate science.
Featured video: saving baby orphaned sloths
(12/06/2011) The world's only sloth sanctuary works to save orphaned and injured sloths in Costa Rica. A recent short film (below) by Lucy Cooke highlights a few of the stars of the sloth sanctuary. Cooke has a new hour long film debuting on Animal Planet on December 17th at 8 PM EST, following the adventures of a number of these sloths.
Yeti crab cultivates bacteria on its claws to feed itself
(12/02/2011) A species of deep-sea crab found in hydrothermal vents off Costa Rica cultivates "gardens" of bacteria on its claws to feed itself, reports Nature News.
Costa Rican fishermen plundering Colombian waters for sharks
(10/14/2011) Costa Rican fishermen have killed some 2,000 sharks in Colombian waters off Malpelo island, a protected area renowned for its marine life, reports Colombia Reports.
Little-known animal picture of the day: salmon-bellied snake
(10/11/2011) The salmon-bellied snake (Mastigodryas melanolomus) is found in Central American forests, savannas, and even agricultural areas. It preys on lizards, frogs, and rodents.
Cameratraps take global snapshot of declining tropical mammals
(08/17/2011) A groundbreaking cameratrap study has mapped the abundance, or lack thereof, of tropical mammal populations across seven countries in some of the world's most important rainforests. Undertaken by The Tropical Ecology Assessment and Monitoring Network (TEAM), the study found that habitat loss was having a critical impact on mammals. The study, which documented 105 mammals (nearly 2 percent of the world's known mammals) on three continents, also confirmed that mammals fared far better—both in diversity and abundance—in areas with continuous forest versus areas that had been degraded.
Photo: six new mini-moths discovered
(07/19/2011) Researchers have discovered six new species of moth from Central America, according to a new paper in Zoo Keys. The moths belong to the primitive Yponomeutidae family, which are commonly known as ermine moths, since some of the species' markings resemble the coat of the ermine.
Animal picture of the day: the adorable scale-crested pygmy tyrant
(07/18/2011) The scale-crested pygmy tyrant is a species of flycatcher that belongs to the passerine order of birds. It is found in tropical forests, including lowland areas and montane forests, and ranges from Costa Rica to Peru and Venezuela.
Ant surprises on Murciélago Islands in Costa Rica
(06/28/2011) The Murciélago Islands are seven small islands off the northwest coast of Costa Rica in the Area de Conservación Guanacaste (ACG), home to one of the largest intact dry tropical forests in Central America. Despite this, few scientists have studied the biodiversity of these small uninhabited islands. A new study in the open access journal Tropical Conservation Science has attempted to rectify this gap by conducting the first survey of insects, specifically ants, on the islands. Researchers were surprised at the richness of ant species on the island: 50 species were documented, only two of which were invasive species.
Environment versus economy: local communities find economic benefits from living next to conservation areas
(06/12/2011) While few would question that conserving a certain percentage of land or water is good for society overall, it has long been believed that protected areas economically impoverish, rather than enrich, communities living adjacent to them. Many communities worldwide have protested against the establishment of conservation areas near them, fearing that less access and increased regulations would imperil their livelihoods. However, a surprising study overturns the common wisdom: showing that, at least in Thailand and Costa Rica, protected areas actually boost local economies and decrease poverty.
Amazon still neglected by researchers
(03/28/2011) Although the Amazon is the world's largest tropical forest, it is not the most well known. Given the difficulty of access along with the fear of disease, dangerous species, indigenous groups, among other perceived perils, this great treasure chest of biology and ecology was practically ignored by scientists for centuries. Over the past few decades that trend has changed, however even today the Amazon remains lesser known than the much smaller, and more secure, tropical forests of Central America. A new study in mongabay.com's open access journal Tropical Conservation Science, which surveyed two prominent international tropical ecology journals (Biotropica and Journal of Tropical Ecology) between 1995 and 2008, finds that Central America was the subject of twice as many studies as the Amazon. In fact, according to the authors, much of the Amazon remains terra incognito to researchers, even as every year more of the rainforest is lost to human impacts.
Top forest policies recognized
(03/23/2011) 19 forest policies have been nominated for an award by the World Future Council, a global think tank.
Good stewards of forests at home outsource deforestation abroad
(11/24/2010) As more nations adopt better laws and policies to save and restore forests at home, they may, in fact, be outsourcing deforestation to other parts of the world, according to a new study in the Proceedings of the National Academy of Sciences (PNAS). Looking at six developing nations where forests are recovering—instead of receding—the study found only one of them did not outsource deforestation to meet local demand for wood-products and food, a process known as 'leakage'.
Photos: ants take top prize at Veolia Wildlife Environment Photography contest
(10/21/2010) An image of nocturnal ant silhouettes systematically devouring a leaf in Costa Rica has given Hungarian photographer, Bence Máté, the much-coveted Veolia Wildlife Environment Photographer of the Year award. In addition to being named Photographer of the year, Máté also won the Erik Hosking award, given to a young photographer (ages 18-26) for a portfolio of images, for images taken in Costa Rica, Brazil, and Hungary.
Photos: world's top ten 'lost frogs'
(08/09/2010) The International Union for the Conservation of Nature (IUCN) and Conservation International (CI) have sent teams of researchers to 14 countries on five continents to search for the world's lost frogs. These are amphibian species that have not been seen for years—in some cases even up to a century—but may still survive in the wild. Amphibians worldwide are currently undergoing an extinction crisis. While amphibians struggle to survive against habitat loss, climate change, pollution, and overexploitation, they are also being wiped out by a fungal disease known as chytridiomycosis.
Inga alley cropping: a sustainable alternative to slash and burn agriculture
(06/14/2010) It has been estimated that as many as 300 million farmers in tropical countries may take part in slash and burn agriculture. A practice that is environmentally destructive and ultimately unstable. However, research funded by the EEC and carried out in Costa Rica in the late 1980s and early 1990s by Mike Hands offers hope that it is possible to farm more successfully and sustainably in these tropical regions.
How an agricultural revolution could save the world's biodiversity, an interview with Ivette Perfecto
(05/04/2010) Most people who are trying to change the world stick to one area, for example they might either work to preserve biodiversity in rainforests or do social justice with poor farmers. But Dr. Ivette Perfecto was never satisfied with having to choose between helping people or preserving nature. Professor of Ecology and Natural Resources at the University of Michigan and co-author of the recent book Nature’s Matrix: The Link between Agriculture, Conservation and Food Sovereignty, Perfecto has, as she says, "combined her passions" to understand how agriculture can benefit both farmers and biodiversity—if done right.
How tree communities respond to distance to edges and canopy openness
(12/06/2009) Tropical forests frequently experience the opening and closing of canopy gaps as part of their natural dynamics. When an edge is created, and the area outside the boundary is a disturbed or unnatural system, forests can be seriously affected even at some distance from the fragmented edge, since sunlight and wind penetrate to a much greater extent. This increases tree mortality and, consequently, canopy openness close to the edge. Thus, canopy openness can be both part of a natural gap-dynamics cycle and the direct manifestation of human edge effects.
Costa Rica proposes to downgrade Las Baulas National Park, threatening leatherback sea turtles
(11/11/2009) Costa Rica is considered by many to be a shining example of environmental stewardship, preserving both its terrestrial and marine biodiversity while benefiting from being a popular tourist location. However, a new move by the Costa Rican government has placed their reputation in question. In May of this year the President of Costa Rica, Oscar Arias, presented a law to the legislature that would downgrade Las Baulas from a National Park to a 'mixed property wildlife refuge'. The downgrading would authorize a number of development projects that conservationists say would threaten the park's starring resident: the leatherback turtle.
Protection of land crabs critical to the conservation of coastal tropical forests
(07/13/2009) The impact of land crabs on the near-ocean forests in which they live has long been overlooked, with emphasis placed instead on water levels, salinity, and other abiotic influences. However, a new research synthesis published in Biological Reviews shows that land crab influence is among the most important factors affecting tropical forest growth along coasts, on islands, and in mangroves.
Conservation through commerce in Costa Rica
(05/25/2009) While Costa Rica is lauded for its conservation ethic, environmental concerns remain in the country. Overdevelopment is tied to many issues, including pollution, degradation of ecosystems, deforestation, and soil erosion, while unsustainable fishing plagues coastal waters. Costa Rica's wildlife is also directly affected by hunting as crop and livestock pests, predation and displacement by introduced species, and the illegal pet trade.
Infant blue whale filmed underwater
(03/06/2009) Off the waters of Costa Rica in January 2008 scientists and photographers with National Geographic filmed an infant blue whale swimming near its mother. They believe this is the first time a baby blue whale has been filmed underwater.
Costa Rica protects green macaw by banning logging of mountain almond tree
(10/27/2008) Costa Rica's high court has prohibited the cutting of a certain species of tree, in part because a highly endangered type of parrot uses the tree almost exclusively for nesting.
Rainforest biodiversity at risk from global warming
(10/09/2008) Climbing temperatures may doom many tropical species to extinction if they are unable to migrate to higher elevations or cooler latitudes, report researchers writing in Science.
Tropical wetlands sequester 80% more carbon than temperate wetlands
(10/08/2008) Tropical wetlands store 80 percent more carbon than temperate wetlands, reports a new study that compared ecosystems in Costa Rica and Ohio.
Biologists attacked in Costa Rica
(08/12/2008) Two ornithologists were attacked by a machete-weilding group while surveying birds in Costa Rica, reports National Geographic.
7 steps to solve the global biodiversity crisis
(08/11/2008) Many biologists believe Earth is entering a sixth mass extinction event, one that has is the direct of human activities, including over-exploitation, habitat destruction and introduction of alien species and pathogens. Climate change — largely driven by anthropogenic forces — is expected to soon increase pressure on Earth's biodiversity. With population and per-capita consumption expected to grow significantly by the mid 21st century, there seems little hope that species loss can be slowed. Nevertheless, writing in the journal PNAS, Stanford biologists Paul R. Ehrlich and Robert M. Pringle suggest seven steps to help improve the outlook for the multitude of species that share our planet.
New Costa Rica guide offers insight on responsible tourism
(08/04/2008) Costa Rica is the world's most popular destination for rainforest tourism thanks to its spectacular biodiversity, relative ease-of-access and safety, and many natural attractions. In 2007 nearly 2 million tourists visited the country, generating almost 2 billion in revenue -- more than the combined income from bananas and coffee.
14 countries win REDD funding to protect tropical forests
(07/24/2008) Fourteen countries have been selected by the World Bank to receive funds for conserving their tropical forests under an innovative carbon finance scheme.
Discovery of new leatherback migration route may help save species
(07/15/2008) Scientists have discovered a new migration route for the world's largest turtle, the leatherback. The route takes the 2,000-pound marine turtle from the Playa Grande beaches in Costa Rica to an area deep in the South Pacific.
Birds face higher risk of extinction than conventionally thought
(07/14/2008) Birds may face higher risk of extinction than conventionally thought, says a bird ecology and conservation expert from Stanford University. Dr. Cagan H. Sekercioglu, a senior research scientist at Stanford and head of the world's largest tropical bird radio tracking project, estimates that 15 percent of world's 10,000 bird species will go extinct or be committed to extinction by 2100 if necessary conservation measures are not taken. While birds are one of the least threatened of any major group of organisms, Sekercioglu believes that worst-case climate change, habitat loss, and other factors could conspire to double this proportion by the end of the century. As dire as this sounds, Sekercioglu says that many threatened birds are rarer than we think and nearly 80 percent of land birds predicted to go extinct from climate change are not currently considered threatened with extinction, suggesting that species loss may be far worse than previously imagined. At particular risk are marine species and specialists in mountain habitats.
Rainforest recovery after deforestation can be enhanced by artificial bat houses
(04/23/2008) "Bat boxes" could help in the recovery of tropical rainforest after deforestation, reports research described in New Scientist Magazine.
Regrowing the rainforest
(03/30/2008) Half a century after most of Costa Rica's rainforests were cut down, researchers from the Boyce Thompson Institute took on a project that many thought was impossible - restoring a tropical rainforest ecosystem.
Three salamander species discovered in Costa Rica
(01/06/2008) Scientists from the Natural History Museum of London have discovered three new species of salamander in south-eastern Costa Rica. This brings the nation's total to forty-three species, meaning that this small tropical nation contains approximately nine percent of the world's salamanders.
Study shows that sea turtles can recover
(12/18/2007) conservation of sea turtle nesting sites is paying off for the endangered reptiles, reports a new study published this week in the journal Global Ecology and Biogeography. A team of researchers led researchers from IUCN and conservation International found that green turtle (Chelonia mydas) nesting on four beaches in the Pacific and two beaches in the Atlantic have increased by an four to fourteen percent annually over the past two to three decades as a result of beach protection efforts.
Global warming will significantly increase bird extinctions
(12/06/2007) Where do you go when you've reached the top of a mountain and you can't go back down? It's a question increasingly relevant to plants and animals, as their habitats slowly shift to higher elevations, driven by rising temperatures worldwide. The answer, unfortunately, is you can't go anywhere. Habitats shrink to the vanishing point, and species go extinct. That scenario is likely to be played out repeatedly and at an accelerating rate as the world continues to warm, Stanford researchers say.
Large-scale agriculture 'compromises' forest's ability to recover
(11/19/2007) As deforestation of tropical forests continues unhindered, one of the future hopes for these damaged ecosystems is regeneration in secondary forests. Some areas that were once slash-and-burned for cattle ranching or subsistence agriculture have been abandoned, allowing scientists to study the possibility of recovery in the rainforest. If anyone has a clear idea of the potential of secondary forests it is Robin L. Chazdon. Dr. Chazdon, a full professor of Ecology and Evolutionary Biology at the University of Connecticut, has been studying the regeneration of secondary forest for over twenty-five years. She has published over 50 papers on tropical ecology, currently she serves as an active member of the Biotropica editorial board and is a member of the Bosques Project, which measures secondary forest recovery in Northern Costa Rica.
Physicists join fight to save amphibians from extinction
(11/19/2007) Physicists have joined the fight to save amphibians from extinction by using Optical Coherence Tomography (OCT) to investigate the properties of frogs skin.
Scientists find treatment for killer frog disease
(10/29/2007) New Zealand scientists have found a treatment for a disease blamed for the death of millions of amphibians worldwide, according to a report from BBC News. However, at best, the cure would only be applicable to captive populations. The disease is killing many amphibians in apparently pristine habitats.
As colorful frog leaps toward extinction, experts look for clues
(10/29/2007) A brightly coloured tropical frog under threat of extinction is the focus of a new research project hoping to better understand how environment and diet influence its development and behaviour.
Costa Rica gets $26M debt-for-nature swap
(10/18/2007) Under an agreement signed Wednesday by the governments of the United States and environmental groups, $26 million of Costa Rican debt will be forgiven in exchange for tropical forest conservation. The debt-for-nature swap comes under the Tropical Forest conservation Act of 1998, legislation intended to allow eligible developing countries to forego paying back debt owed to the U.S. in exchange for supporting local tropical forest conservation activities.
Do Costa Rica's payments for environmental services work?
(09/17/2007) While Costa Rica is now known as a world leader for conservation policies and ecotourism, the Central American country had some of the world's highest deforestation rates prior to establishing its reputation. Clearing for cattle pasture and agriculture destroyed much of the country's biodiverse rainforests in the 1960s and 1970s.
Two new species of salamander discovered in Panama
(09/09/2007) Scientists have discovered two new species of salamanders from the mountainous Costa Rica-Panama border region. The findings, published by David B. Wake, Jay M. Savage, and James Hanken in the journal Copeia, push the number of salamanders known in the region to 24, making it a hotspot in terms of salamander biodiversity.
"Virgin" rain forests of Costa Rica a misnomer
(07/25/2007) Radiocarbon dating of montane forest soils in Costa Rica uncovered evidence of charcoal that shows its otherwise "virgin" tropical forests are less than 200 years old. The findings, published in the journal Biotropica, have implications for the re-establishment of rain forests after clearing.
Poverty and corruption reduce effectiveness of rainforest parks
(07/09/2007) Poverty and corruption are linked to higher incidence of fire in tropical forest reserves, reports a new study published in the journal Ecological Applications. Poor, corrupt countries -- like Cambodia, Guatemala, Paraguay, and Sierra Leone -- have the least effective parks when measured in terms of the incidence of fire relative to surrounding "buffer" areas. The findings have significant implications for rainforest conservation efforts.
Coffee plantations may preserve tropical bird species
(06/18/2007) Agricultural areas offer opportunities for conservation in deforested landscapes in the tropics, reports a study published in the April 2007 issue of the journal conservation Biology by Stanford University biologists.
An interview with author and eco-lodge pioneer Jack Ewing
(06/12/2007) In 1970 a young man went to Costa Rica, a place he initially confused with Puerto Rico, on an assignment to accompany 150 head of cattle. 37 years and several lifetimes' worth of adventures later, Jack Ewing runs a eco-lodge that serves as a model for a country now considered the world leader in nature travel.

Frogs avoid damaging UV-B radiation, reducing extinction risk
(04/18/2007) Poison arrow frogs appear to make special effort to avoid exposure to damaging ultraviolet-B radiation, according to research published in the journal Biotropica. The findings are significant in light of increasing levels of UV-B radiation due to ozone depletion.
Bad news for frogs; amphibian decline worse than feared
(04/16/2007) Chilling new evidence suggests amphibians may be in worse shape than previously thought due to climate change. Further, the findings indicate that the 70 percent decline in amphibians over the past 35 years may have been exceeded by a sharp fall in reptile populations, even in otherwise pristine Costa Rican habitats. Ominously, the new research warns that protected areas strategies for biodiversity conservation will not be enough to stave off extinction. Frogs and their relatives are in big trouble.
Racing sea turtle named in honor of Stephen Colbert
(04/13/2007) An eleventh turtle named Stephanie Colburtle has joined competitors Yahoo!, Travelocity, Plantronics, West Marine, Dreyer's Ice Cream and other sponsors in The Great Turtle Race, a unique international sea turtle conservation event that will take place online from April 16 to April 29 in a global bid to raise awareness and funds for the critically endangered leatherback turtle.

Pesticides threaten cloud forests in Costa Rica - new study
(01/22/2007) Pesticides from coffee and banana cultivation are accumulating in Costa Rica's biodiverse cloud forests according to research published earlier this month in Environmental Science & Technology. The findings have implications for conservation efforts in both the Central American country and in other parts of the world.
Avoided deforestation could send $38 billion to third world under global warming pact
(11/01/2006) Avoided deforestation will be a hot point of discussion at next week's climate meeting in Nairobi, Kenya. Already a coalition of 15 rainforest nations have proposed a plan whereby industrialized nations would pay them to protect their forests to offset greenhouse gas emissions. Meanwhile, last month Brazil -- which has the world's largest extent of tropical rainforests and the world's highest rate of forest loss -- said it promote a similar initiative at the talks. At stake: potentially billions of dollars for developing countries. When trees are cut greenhouse gases are released into the atmosphere -- roughly 20 percent of annual emissions of such heat-trapping gases result from deforestation and forest degradation. Avoided deforestation is the concept where countries are paid to prevent deforestation that would otherwise occur. Policymakers and environmentalists alike find the idea attractive because it could help fight climate change at a low cost while improving living standards for some of the world's poorest people and preserving biodiversity and other ecosystem services. A number of prominent conservation biologists and development agencies including the World Bank and the U.N. have already endorsed the idea.
Brazil proposes compensation plan for rainforest conservation
(10/16/2006) Last month Brazil proposed the establishment of a fund to compensate developing countries that reduce deforestation, a move that follows a similar initiative by a coalition of developing countries led by Papua New Guinea and Costa Rica. The scheme could help cut greenhouse gas emissions that result from forest clearing and conversion. Deforestation currently is responsible for 20-25 percent of such heat-trapping emissions.

Scientists endorse plan to save rainforests through emissions trading
(05/19/2006) The Association for Tropical Biology and conservation (ATBC), the world's largest scientific organization devoted to the study and wise use of tropical ecosystems, has formally endorsed a radical proposal to help save tropical forests through carbon trading. Under the initiative proposed by an alliance of fifteen developing countries led by Papua New Guinea and Costa Rica, tropical nations that show permanent reductions in deforestation would be eligible to receive international carbon funds from industrial nations who could purchase carbon credits to help them meet their emissions targets international climate agreements like the Kyoto Protocol.
Rainforests worth $1.1 trillion for carbon alone in Coalition nations
(11/29/2005) If a coalition of developing countries has its way, there could soon be new forests sprouting up in tropical regions. The group of ten countries, led by Papua New Guinea, has proposed that wealthy countries pay them to preserve their rainforests. The Coalition for Rainforest Nations argues that all countries should pay for the benefits -- from carbon sequestration to watershed protection -- that tropical rainforests provide.
