New protections for coral reefs and dwindling fish species in Belize
(04/27/2009) Coral reefs in Belize, considered to be some of the most pristine in the west, have secured additional protections. Rene Montero, the Minister of Agriculture and Fisheries, signed a set of new laws this month to protect Belize’s coral reefs and the fish that inhabit them. The additional laws protect increasingly overfished species, ban spearfishing in marine reserves, and create no-take zones, according to a press release from the Wildlife Conservation Society (WCS).
Plant communities changing across the globe, says scientist Sasha Wright
(03/29/2009) Having studied plant communities across three continent and within widely varied ecosystems—lowland tropics, deciduous forests, grasslands, and enclosed ecosystems on hill-tops—graduate student Sasha Wright has gained a unique understanding of shifts in plant communities worldwide as they respond to pressures from land use and global climate change. “Plant communities are certainly changing,” Wright told Mongabay.com in a March 2009 interview. “These changes are undoubtedly affected by an increased occurrence of extreme weather events, temperature fluctuations, atmospheric CO2 concentrations, human land use, and in some cases urbanization of populations.”
Territorial disputes and conservation
(03/23/2009) Political drivers such as those related to territorial disputes between tropical countries can result in direct and indirect ramifications negatively impacting conservation of native ecosystems report Arlenie Perez, Chuang Chin-Ta and Farok Afero in the March issue of the open access journal Tropical Conservation Science.
Climate change could devastate lizards in the tropics
(03/04/2009) With help from data collected thirty years ago, scientists have discovered that tropical lizards may be particularly sensitive to a warming world. Researchers found that lizards in the tropics are more sensitive to higher temperatures than their relatives in cooler, yet more variable climates. "The least heat-tolerant lizards in the world are found at the lowest latitudes, in the tropical forests. I find that amazing," said Raymond Huey, lead author of a paper appearing in the March 4 Proceedings of the Royal Society B.
Salamander populations collapse in Central America
(02/09/2009) Salamanders in Central America — like frogs, toads, and other amphibians at sites around the world — are rapidly and mysteriously declining, report researchers writing in the journal Proceedings of the National Academy of Sciences. Disturbingly, salamanders are disappearing from protected areas and otherwise pristine habitats.
Chocolate has been a delicacy north of Mexico for a thousand years
(02/02/2009) Chocolate, produced from cacao beans, has been a part of American culture for a thousand years according to new paper published in the Proceedings of the National Academy of Sciences. Analyzing chemical residue from jars of native peoples in New Mexico, researchers Patricia Crown and Jeffrey Hurst discovered theobromine, a chemical signature of cacao. The jars have been dated from 1000 to 1125 AD, well over three hundred years before Columbus and the earliest recorded discovery of cacao north of Mexico. The cacao jars are from Pueblo Bonito, an archaeological site in Chaco Canyon, which is located in northwestern New Mexico. Chaco Canyon, once home to 2,000-5,000 inhabitants, was composed of a dense group of pueblos, of which Bonito was the largest. Incorporating 800 rooms, Pueblo Bonito was the center of a number of towns and villages in Chaco Canyon.
Shade-grown coffee preserves native tree diversity
(12/23/2008) A new study finds that shade-grown coffee protects the biodiversity of tree species, as well as those of birds and bats.

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.

Researchers discover "artistic" moth in Panama
(07/29/2008) Researchers have discovered a new species of Bagworm Moth that wraps its eggs individually in "beautiful cases" fashioned from its golden abdominal hairs, according to a new paper published in the Annals of the Entomology Society of America. The behavior is unique among insects.
Climate change will increase the erosion of coral reefs
(07/28/2008) Coral reefs are particularly susceptible to climate change. Warming waters have been shown to bleach coral, killing off symbiotic algae that provide them with sustenance, and often leading to the death of the coral itself. Much attention has been placed on bleaching coral, but now scientists have discovered an additional danger to coral reefs in a warming world: erosion.
Mangroves are key to healthy fisheries, finds study

Defaunation, like deforestation, threatens global biodiversity
(05/20/2008) Loss of wildlife is a subtle but growing threat to tropical forests, says a leading plant ecologist from Stanford University. Speaking in an interview with mongabay.com, Dr. Rodolfo Dirzo says that the disappearance of wildlife due to overexploitation, fragmentation, and habitat degradation is causing ecological changes in some of the world's most biodiverse tropical forests. He ranks defaunation — as he terms the ongoing biological impoverishment of forests — as one of the world's most significant global changes, on par with environmental changes like global warming, deforestation, and shifts in the nitrogen cycle.
Frog chooses whether to lay eggs on land or in water
(05/19/2008) Researchers in Panama have discovered a frog that can choose whether it lays its eggs on land or in water. It is the first time such "reproductive flexibility" has been found in a vertebrate.

Only 150 vaquita remain
(11/19/2007) Only 150 individual vaquita, the world's smallest cetacean, remain, according to a new study published in conservation Biology. The species has been decimated as accidental bycatch in fishing nets in its Gulf of California habitat. Researchers--who say there may be only a two-year window to save the species from extinction--have launched a last-ditch conservation effort.
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.
7-year old nature guide becomes Belize environmental hero as adult
(11/16/2007) Each year hundreds of thousands of nature-oriented tourists visit Belize to see the Central American country's spectacular coral reefs, biodiverse rainforests, and ancient Mayan ruins. However few visitors realize that Belize's natural resources are at risk. Timber and oil extraction, agricultural encroachment, coastal development, pollution and unrestrained tourism are all increasing threats to Belizean ecosystems. Unless something is done to address these concerns, within a generation these pressures could present considerable problems for Belize. Dr. Colin Young, head of the environmental science program at Galen University in Belize, says that while he is greatly concerned about these issues, there is still time to ensure healthy forests and reefs in Belize.
