Thirteen countries with wild tiger populations agreed Tuesday to take part in a global count to establish how many of the critically endangered animals are left and improve policies to protect them.
A biologist at the University of York is part of an international team which has shown that advanced DNA sequencing technologies can be used to accurately measure the levels of inbreeding in wild animal populations.
Using new genetic tools, the authors conclude that the first significant expansion of human populations appears to be much older than the emergence of farming and herding, dating back to the Paleolithic (60,000-80,000 years ...
A new study highlights the complex factors at play for parasites that infect animal populations residing on small islands. The findings are important for understanding colonization and extinction as drivers of island biogeography.
(Phys.org) —With estimates of losing 15 to 40 percent of the world's species over the next four decades – due to climate change and habitat loss, researchers ponder in the Sept. 26 issue of Nature whether science should ...
It has long been known that the characteristics of many plants with wide ranges can vary geographically, depending on differences in climate. But changes in grazing pressure and pollination can also affect the genetic composition ...
Somewhere between the ideas of resurrecting extinct species and engaging in genetic engineering of existing ones lies space for a conversation about a third potential approach to fending off conservation disaster.
Japanese scientists have launched a sperm bank for endangered animals that uses freeze-drying technology they hope could one day help humans recreate animal populations on other planets, the chief researcher said Wednesday.
You'd think it would take a pretty exotic ecosystem to surprise Chris Whittier, V97. He has, after all, treated wild gorillas in six national parks in central Africa.
A new species of fungus that eats amphibians' skin has ravaged the fire salamander population in the Netherlands, bringing it close to regional extinction.
