| 'Tree of life' for 2.3 million species released Posted: 18 Sep 2015 03:03 PM PDT A first draft of the tree of life for all 2.3 million named species of animals, plants, fungi and microbes has been released. Thousands of smaller trees have been published over the years for select branches, but this is the first time those results have been combined into a single tree. The end result is a digital resource that is available online for anyone to use or edit, much like a 'Wikipedia' for evolutionary relationships. |
| How the chameleon climbed to the top of the tree Posted: 18 Sep 2015 07:54 AM PDT The chameleon's exceptional tree-climbing ability is dependent on vital ball-and-socket joints in its wrists and ankles, according to new research. The study also finds that chameleons have twice the number of wrist and ankle skeletal elements than previously thought, and explains how they evolved to live in the trees. |
| 58,046 fruit flies shed light on 100-year old evolutionary question Posted: 18 Sep 2015 07:54 AM PDT In flies, small wings are normally rounder than large wings. Researchers bred fruit flies to change that relationship as a way to explore the limits of evolution and shed light on a question that biologists have puzzled over for the last 100 years. |
| China's protection of giant pandas good for other species too Posted: 16 Sep 2015 01:18 PM PDT China has invested substantially in nature reserves to protect giant pandas in the wild. A new study finds that in addition to benefiting the charismatic pandas, the reserves also protect substantial numbers of other species threatened with extinction, including many endemic species of forest birds, mammals and amphibians. |
| Counting underwater vital for marine conservation Posted: 16 Sep 2015 01:18 PM PDT Understanding how genetic diversity occurs within species is paramount for conservation, according to scientists. The new research identified regions of high and low multi-species genetic diversity in Australia's marine waters. Varying genetic diversity had implications for both marine conservation and broader understanding of how species form. |
| Saving the last groups of wild Sumatran rhinoceros Posted: 16 Sep 2015 01:18 PM PDT Researchers carried out an island-wide survey of the last wild population of Sumatran rhinoceros, and now recommend that wildlife conservation managers consolidate the small population, provide strong protection for the animals, determine the percent of breeding females remaining and 'recognize the cost of doing nothing.' |
