| Ancient hybridization key to domestic dog's origin, wolf conservation efforts Posted: 01 Sep 2015 01:12 PM PDT The ancestry of man's best friend is more complicated than its furry coat and soulful eyes betray. Understanding the evolutionary history of the domesticated dog may help protect endangered wolves, according to a study that offers an overview examining the system used to classify dogs and related animals. |
| Climate change will irreversibly force key ocean bacteria into overdrive Posted: 01 Sep 2015 11:02 AM PDT The levels of ocean acidification predicted for the year 2100 have been shown to cause an irreversible evolutionary change to a bacteria foundational to the ocean's food web. |
| Saving oysters by digging up their past Posted: 01 Sep 2015 09:10 AM PDT Restoring oyster reefs is not an easy task, but by digging deep and examining centuries-old reefs, marine restoration professionals may stand a better chance at bringing oysters back, suggests a new study. |
| Heat and acid could squeeze trout out of southern Appalachian streams Posted: 01 Sep 2015 08:35 AM PDT A newly published research study that combines effects of warming temperatures from climate change with stream acidity projects average losses of around 10 percent of stream habitat for coldwater aquatic species for seven national forests in the southern Appalachians -- and up to a 20 percent loss of habitat in the Pisgah and Nantahala National Forests in western North Carolina. |
| Fossil specimen reveals a new species of ancient river dolphin Posted: 01 Sep 2015 06:55 AM PDT The careful examination of fossil fragments from Panama has led Smithsonian scientists and colleagues to the discovery of a new genus and species of river dolphin that has been long extinct. The team named it Isthminia panamensis. The specimen not only revealed a new species to science, but also shed new light onto the evolution of today's freshwater river dolphin species. |
