- 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.
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...

In 48 years wildlife populations in the tropics, the region that holds the bulk of the world's biodiversity, have fallen by an alarming 61 percent, according to the most recent update to the Living Planet Index. Produced by the World Wide Fund for Nature (WWF) and the Zoological Society of London (ZSL), the index currently tracks almost 10,000 populations of 2,688...

At the end of March in southern Belize the sun beats down through blackened trees onto what was the only known low-lying sphagnum moss bog in Central America. Now it is an expanse of ash and pale crusts of burned moss onto which dragonflies settle briefly before passing on. Fire spread through the area at the end of February 2012, and since then reeds have...

- 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.
- A NASA funded expedition using airborne lasers to study ancient Mayan ruins has also documented widespread illegal deforestation in the Caracol Archaeological Reserve. The lasers found that forest disturbance was actually 58 percent greater than recent satellite surveys showed, according new study in mongabay.com's open access journal Tropical Conservation Society (TCS). Such deforestation not only imperils biodiversity, carbon storage, and migration routes for Central American species, but...

- Remote camera traps, which have become a hugely important conservation tool on land during the past decade, have now gone underwater. Marine biologists have used underwater video camera traps to compare the population of Caribbean reef sharks (Carcharhinus perezii) in Belize's protected areas versus fishing areas in a new study in the open-access journal PLoS ONE. Conducted from 2005-2010, the study found that reef sharks benefited significantly from conservation areas.
