In an unprecedented research project, 30 juvenile green sea turtles of varying ages have been released directly into the waters off Grand Cayman, the largest of the Cayman Islands, wearing tiny tracking devices that will monitor their movements.The turtles carry prototype micro-satellite tags, weighing less than a penny and safely attached to the turtles’ shells using epoxy and neoprene-silicone mounts.

A study by Brazilian researchers demonstrated its antimicrobial action in vitro, via inhibition of the activity of bacterial plaque biofilm containing several types of cariogenic microorganisms, including Streptococcus mutans, one of the most common bacteria found in the human oral cavity.

Current protected area networks in South and Southeast Asia fail to conserve socio-economically important native tree species and their seed sources, according to a new region-wide threat assessment. The study’s findings highlight priority areas and synergies for coordinating conservation and restoration of critical habitat for these species. This will be vital to ensure continued provision of ecosystem services and support the livelihoods and nutrition security of millions of people that depend on them.

Brazilian researchers demonstrate in field experiments that these large mammals help keep a balance between areas with different levels of productivity in biomes like the Atlantic Rainforest, and regulate the spatial structure of plant communities.

Genetic analyses helped identify a new cryptic shark species of the genus Squatina from the Western Atlantic Ocean.

Given the significant number of cities affected by disasters such as floods, landslides and drought in the South and Southeast, the study focused on these regions and selected 45 cities in seven metropolitan areas affected by disasters in recent years.

Methods such as interviews with people who live near conservation units may lead to mistakes, such as distinguishing between deer species on the basis of spots like those on this newborn Pampas deer.
