(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.
