For a species with approximately 500 surviving animals in the world, this was a crisis — an unprecedented die-off signalling a troubled outlook for the species.

Study documents local extinction of pikas from the largest area yet reported and projects climate change will cause drastic decline for the charismatic mammal within decades.

Human antidepressants are building up in the brains of bass, walleye and several other fish common to the Great Lakes region, scientists say.

A team of scientists has discovered that a 1°C rise in local sea temperature has massive impacts on an Antarctic marine community. These new results are published this week (31 August) in the journal Current Biology, and enable researchers to better understand the biological implications of the future ocean warming predicted by the Intergovernmental Panel on Climate Change (IPCC).

Pines in Canada and Much of U.S. at Risk.

Scientists used historical data and models to predict the impacts of six planned or potential Andean dams on the Amazon river system.

One white-faced capuchin monkey sticks its fingers deep into the eye sockets of another capuchin it’s friends with. A capuchin uses her ally’s body parts to whack their common enemy. These behaviors become entrenched in the repertoires of the inventors. But in the first case, the behavior spreads to other group members, and in the second case it does not.

Australian tiger snakes have “hit the jackpot” because prey cannot evolve resistance to their venom.

Non-toxic, lubricant-infused coatings deter mussels and prevent their attachment by disrupting their mechanosensory and adhesive systems.

Bumblebees are less able to start colonies when exposed to a common neonicotinoid pesticide, according to a new University of Guelph study.

Prof. Nigel Raine has discovered that exposure to thiamethoxam reduces the chances of a bumblebee queen starting a new colony by more than one-quarter.
