First, many communities seldom, if ever, attain an equilibrium number of species. Both natural and anthropogenic disturbances like hurricanes, volcanic eruptions, and clear-cutting can remove species and open up habitat. Evolution can add species to either the .

      Most interesting, perhaps is the compelling evidence suggesting that Murres/Guillemots (Uria sp.) are hosts for IAV. Research to investigate IAV in murres dates back to the s, and interest in these birds has been renewed with increased sampling effort in the past 10 years.

Waterbird communities are potential indicators of ecological changes in threatened wetland ecosystems and consequently, a potential object of ecological monitoring programs. Waterbirds often breed in largely inaccessible colonies in flooded habitats, so unmanned aerial vehicle (UAV) surveys provide a robust method for estimating their breeding population by: 6.

The Bering Sea ecosystem can be divided into five major regions: the eastern Bering Sea, the Aleutian Islands, the Gulf of Alaska, the Aleutian Basin, and the western Bering Sea. Mass mortality events are increasing in frequency and magnitude, potentially linked with ongoing climate change.

In October through JanuarySt. Paul Island, Bering Sea, Alaska, experienced a mortality event of alcids (family: Alcidae), with over carcasses recovered. Almost three-quarters of the carcasses were unscavenged, a rate much higher than in baseline surveys (17% Cited by: 3.

Journal of Wildlife Management publishes on wildlife science such as investigations into the biology/ecology of wildlife that has implications for conservation.Seabird colonies occur exclusively for the purpose of breeding; non-breeding birds will only collect together outside the breeding season in areas where prey species are densely aggregated.

Seabird colonies are highly variable. Individual nesting sites can be widely spaced, as in an albatross colony, or densely packed as with a murre colony. The really hot bird news in the United States is the presence of a White-crested Elaenia on Texas' South Padre Island.

This is the first time this species has been seen in .
