According to a new study, the precise patterning of bird feathers relies on signaling through ectodysplasin (EDA) and its receptor EDAR -- the same signaling pathway known to be crucial for the formation of hair follicles, teeth and scales in fish, lizards and mammals.
To better understand the effects of climate change on the bird community in the Sierra Nevada region, researchers examined the impacts to birds from a recent extreme drought (2013-2016). The drought resulted in the widespread death of pine trees due to attacks by bark beetles, potentially impacting wildlife habitat. While the results were varied, researchers […]
The world's largest coordinated network of protected areas is not located at the South Pole or in Australia, Africa, Asia or on the American continents -- but in Europe. An international team of researchers has examined how effectively Natura 2000 protects listed habitat types in Germany. The result: although the existing network includes sites of […]
