California’s Central Valley and the Colorado River Delta host more than 82 million birds every year during the fall migration, according to a new study published in the journal Ornithological Applications.

Arctic sea ice is rapidly diminishing due to global warming, and scientists have found that sea ice dynamics have a big impact on circulation and precipitation patterns in Arctic Alaska, which lies at a climatological crossroads between the Arctic and North Pacific oceans. 

Scientists have developed a new technique for remotely surveying elephants and other wildlife that is quicker and has the same accuracy as human counts done on the ground or in low-flying airplanes.

Study assesses where bird species would exist.

In a study of local rivers, experts at the University of Nottingham have discovered more invertebrates – animals without a backbone, such as insects and snails - living on litter than on rocks.

A new study from the Institut de Ciències del Mar (ICM-CSIC, Spain) and the National Oceanography Centre brings unprecedented insights into the environmental constraints and climatic events that controlled the formation of these reefs.

Harbor porpoises have rebounded in a big way off California. Their populations have recovered dramatically since the end of state set-gillnet fisheries that years ago entangled and killed them in the nearshore waters they frequent.

Expansion provides additional protection for critical habitat and important fish species

The Tiger Rattlesnake possesses the simplest, yet most toxic venom of any rattlesnake species, and now new research from a team lead by a University of South Florida biologist can explain the genetics behind the predator’s fearsome bite.

Protected areas are critical to mitigating extinction of species; however, they may also be in conflict with efforts to feed the growing human population.
