FishBrain and U.S. Fish and Wildlife Service Partner to Create App-powered Citizen Science Engagement Opportunity Tracking Endangered Species
-
The U.S. Fish and Wildlife Service – the federal government agency dedicated to the conservation of fish, wildlife, plants and their habitats – has teamed up with FishBrain – the world’s largest free-to-use app and social network for anglers – to launch a new feature of the app that will help the American public identify and document threatened, endangered and candidate species.

Genetics Provide New Hope for Endangered Freshwater Mussels
-
A piece of the restoration puzzle to save populations of endangered freshwater mussels may have been found, according to a recent U.S. Geological Survey led study. Local population losses in a river may not result in irreversible loss of mussel species; other mussels from within the same river could be used as sources to restore declining populations.

Increasing Northern Hemisphere water deficit
-
A monthly water-balance model is used with CRUTS3.1 gridded monthly precip- itation and potential evapotranspiration (PET) data to examine changes in global water deficit (PET minus actual evapotranspiration) for the Northern Hemisphere (NH) for the years 1905 through 2009. Results show that NH deficit increased dramatically near the year 2000 during both the cool (October through March) and warm (April through September) seasons. The increase in water deficit near 2000 coincides with a substantial increase in NH temperature and PET. The most pronounced increases in deficit occurred for the latitudinal band from 0 to 40°N. These results indicate that global warming has increased the water deficit in the NH and that the increase since 2000 is unprecedented for the 1905 through 2009 period. Additionally, coincident with the increase in deficit near 2000, mean NH runoff also increased due to increases in P. We explain the apparent contradiction of concurrent increases in deficit and increases in runoff.
