| Plastic in 99 percent of seabirds by 2050 Posted: 31 Aug 2015 01:37 PM PDT Researchers from CSIRO and Imperial College London have assessed how widespread the threat of plastic is for the world's seabirds, including albatrosses, shearwaters and penguins, and found the majority of seabird species have plastic in their gut. |
| Endangered animals can be identified by rate of genetic diversity loss Posted: 31 Aug 2015 11:02 AM PDT A new study presents a novel approach for identifying vertebrate populations at risk of extinction by estimating the rate of genetic diversity loss, a measurement that could help researchers and conservationists better identify and rank species that are threatened or endangered. |
| Species lines blur between two sparrows in New England's tidal marshes Posted: 31 Aug 2015 11:02 AM PDT Among birds, the line between species is often blurry. Some closely related species interbreed where their ranges overlap, producing hybrid offspring. In the coastal marshes of New England, this has been happening between the Saltmarsh Sparrow and Nelson's Sparrow. Research finds that appearance alone is not enough to identify these hybrid zone birds. |
