Common pesticide inhibits brain development in frogs

New research published in Environmental Toxicology & Chemistry reveals that low doses of a commonly used pesticide potentially harm the Northern Leopard frog by inhibiting their brain development.

The pesticide chlorpyifos, which has been used since 1965 in both agricultural and non-agricultural areas, had clear effects on Northern Leopard tadpoles' neurodevelopment, even in situations where the...

New research could reduce primate electrocutions and help conservation strategies

New research has mapped and analysed the incidence of primate electrocutions in Diani, Kenya to identify hotspot areas that should be prioritised to reduce the risk of electric shock. The study could also inform conservation strategies in other parts of the world where primate electrocutions are common. Electrocution threatens a wide range of primate species...

Bees coordinate strategy for defending colony

The Brazilian stingless bee Tetragonisca angustula (jataĆ­ in Portuguese) deploys a different strategy for defending its nests from other social insect species. In addition to posting sentinels at the nest entrance, as do most social insects, colonies of this species also have guards that hover near the entrance all the time.

A study by researchers in...
