Comment on the proposed conservation of Hydromantes Gistel, 1848, by the designation of Salamandra genei Temminck & Schlegel, 1838, as the type species (Case 2868; see BZN 50:219-223; 51:149-153; 52:183-186) Comment on the proposed conservation of Hydromantes Gistel, 1848, by the designation of Salamandra genei Temminck & Schlegel, 1838, as the type species (Case 2868; see BZN 50:219-223; 51:149-153; 52:183-186)

Sea otters and kelp forests in Alaska: Generality and variation in a community ecological paradigm Sea otters and kelp forests in Alaska: Generality and variation in a community ecological paradigm
Multiscale patterns of spatial and temporal variation in density and population structure were used to evaluate the generality of a three—trophic—level cascade among sea otters (Enhydra lutris), invertebrate herbivores, and macroalgae in Alaska. The paradigm holds that where sea otters occur herbivores are rare and plants are abundant, whereas when sea otters are absent herbivores are...

Repertoire, structure, and individual variation of vocalizations in the sea otter Repertoire, structure, and individual variation of vocalizations in the sea otter
Vocalizations of the California sea otter (Enhydra lutris nereis) were recorded from wild and captive adults and young and analyzed spectrographically. Parameters measured from the sonagrams included fundamental frequency, duration, maximum frequency, intercall interval, and the location and amplitude of energy peaks. We identified 10 basic vocal categories, one of which consisted of...

Spatial and temporal trends of contaminants in eggs of wading birds from San Francisco Bay, California Spatial and temporal trends of contaminants in eggs of wading birds from San Francisco Bay, California
Between 1989 and 1991, reproduction by black-crowned night-herons (Nycticorax nycticorax) and snowy egrets (Egretta thula) was studied at sites in San Francisco Bay. Eggs were collected from these and other bay sites and from South Wilbur Flood Area, a reference site in California's San Joaquin Valley. Eggs were analyzed for inorganic trace elements, organochlorine pesticides, and...
