Manatees have just been downlisted from endangered to threatened; and while some are celebrating their recovery, many advocates are fearing that the move puts their future survival in jeopardy.

Music can be a powerful form of expression. It’s especially important for songbirds such as zebra finches, which learn the songs of their fathers in order to court mates.

Land snails are generally believed to be ground-dwelling creatures, preferring dark and humid places, like the forest floor, or a suburban garden. So why do we find some species of snails in the tops of trees, where it is relatively light and dry? Associate Professor Ikuyo Saeki from the University of Tsukuba, Japan and her colleagues from Hokkaido University and other institutions, have performed some fascinating research to find out why.

A new methodology developed by the Indian Statistical Institute, and WCS (Wildlife Conservation Society) may revolutionize how to count tigers and other big cats over large landscapes.

U.S. Geological Survey scientists teamed up with government, nonprofit, and university partners in South Florida's Big Cypress National Preserve to hold a scientific scavenger hunt for nonnative and invasive freshwater fish species.

How a disease outbreak affects a group of animals depends on the breakdown of ages in the population, an animal study has shown.

A bumble bee that is quickly disappearing will finally get the protection it needs under the Endangered Species Act.

For migratory birds, breeding grounds are where the action is. But a new study by University of Guelph biologists is among the first to suggest that the number of songbirds breeding during spring and summer depends mostly on what happens at their wintering grounds.

With as many as 140 species, Atractus is the most diverse snake genus in the world, even though it can be found exclusively in Central and South America. However, these colubrid ground snakes seem largely under-researched, since there have been thirty-three species discovered in the last ten years only.

Effects of livestock grazing on greater sage-grouse populations can be positive or negative depending on the amount of grazing and when grazing occurs, according to research published today in Ecological Applications. The research was conducted by scientists from the United States Geological Survey, Colorado State University and Utah State University.
