NOAA scientist Carol Stepien will present research results at a public forum this week in Toledo, Ohio, on how local bait shops, anglers and the public can prevent invasive fish from accidentally being released into the Great Lakes.

A population of exotic invasive Cuban treefrogs has been discovered in New Orleans, more than 430 miles (700 kilometers) from the nearest known population in Florida, making this the first known breeding population in the mainland United States outside that state, reports a new study by the U.S. Geological Survey.

When the rains eventually blanket northwest Costa Rica, ushering in the country’s wet season, a booming chorus of yellow toads will fill the tropical forest.

Primatologist Jane Goodall came to the University of Toronto over the weekend to mark Earth Day with a discussion about her life, work and the need to protect the planet.

A new WCS paper published in the journal BioScience finds that the enormous trends toward population stabilization, poverty alleviation, and urbanization are rewriting the future of biodiversity conservation in the 21st century, offering new hope for the world’s wildlife and wild places.

The vampire bat lives up to its name. Its diet consists of blood, which it gets by biting animals and lapping up their blood. The vampire bat prefers to feed on domestic animals such as cows and pigs. When it does so, there is a risk of transmission of pathogens such as rabies. Now, a new study lead by Assistant Professor Kristine Bohmann from the Natural History Museum of Denmark, University of Copenhagen, describes a new DNA method to efficiently screen many vampire bat blood meal and faecal samples with a high success rate and thereby determine which animals the vampire bats have fed on blood from. Furthermore, the authors show that the technique can be used to simultaneously assess the vampire bat’s population structure.

“Take a deep breath” is the mantra of every anxiety-reducing advice list ever written. And for good reason. There’s increasing physiological evidence connecting breathing patterns with the brain regions that control mood and emotion.

Instead of waking up before dawn to milk cows manually, many dairy farmers now use robots to milk — and those robots do more than just milk cows. They can also provide valuable information about the animals’ overall health.

Shifts in the timing of life cycle events – known as phenology - of interacting species, such as predator versus prey and plant versus pollinator, are often listed as a consequence of climate change.

For centuries people have claimed that strange behavior by their cats, dogs and even cows can predict an imminent earthquake, but the first rigorous analysis of the phenomenon concludes that there is no strong evidence behind the claim.
