DNA barcode finds four new bird species
...h of DNA -- a so-called DNA barcode -- can be used genetically
to identify known species and to find new ones. "A uniform system to use DNA to identify all plants and animals would allow many more people -- from environmental regulators to nature lovers -- to identify organisms," says Mark Y. Stoeckle, M.D., g...
Tracing genes, biologists show lizard migration is traced to Florida
...searchers have found that there are at least eight genetically
distinct groups of the lizard. In the late 1800s, Anolis sagrei was introduced (probably through a shipment of goods) to the Florida Keys, got a toehold and, after a decades-long lag, began spreading into the Florida mainland in the 1940s, most like...
