A new treefrog species was discovered during a two-week expedition to a remote tabletop mountain at Cordillera del Cóndor, a largely unexplored range in the eastern Andes.

The sex of turtle hatchlings is determined by temperature, and at present about 52% of hatching green turtles - one of seven species of sea turtle - are female. But a study by the University of Exeter and the Marine and Environmental Sciences Centre (Portugal) shows that in warmer temperatures predicted by Intergovernmental Panel on Climate Change (IPCC) scenarios, 76-93% of hatchlings would be female.

By 2050, almost 70 percent of the world’s population will live in urban environments, according to the United Nations. But as cities spread, wild animals will also have to adapt. In Nature Ecology and Evolution, researchers working at the Smithsonian Tropical Research Institute (STRI) report that male tungara frogs in Panama City put on sexier mating displays than frogs living in nearby tropical forests.

In collaboration with the National Autonomous University of Nicaragua, a research group from the UPV/EHU’s Plentzia Marine Station has studied the bivalves in the mangroves on both coasts of Nicaragua in order to analyse how they are affected by the pollution brought down by the rivers. That way, it will be possible to use them as sentinels or indicators of environmental changes. The research has been published by the journal Science of the Total Environment.

An international study led by University of Miami tropical biologists reveals that tropical trees are migrating upslope to escape climate change, but not fast enough.
