To find out how rising temperatures could affect species diversity, biologists from the German Centre for Integrative Biodiversity Research (iDiv) and the Leipzig University have developed a simple experiment: they covered the bottom of different Petri dishes with litter material, then put in two species of springtails, that is, arthropods only a few millimetres in size, and then added mites feeding on springtails. Subsequently, for some of the Petri dishes they increased the ambient temperature from originally 13.5°C to 18.5°C and for some other Petri dishes to 23.5°C. In those Petri dishes, the temperatures were hence five, respectively ten degrees higher than the conditions to which the animals had been exposed to in long-term cultures over years. This created simplified miniature ecosystems under climate change conditions, in which the springtail species that peacefully coexist in the wild represented the prey, and the mites represented the predators. For two months, the researchers then observed how the interactions between the three species would develop with different temperatures.

Hybridization, or the interbreeding of species, is increasing between native and invasive trout across the northern Rocky Mountains, according to a study released Tuesday by the U.S. Geological Survey and partners.

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.
