Conservation issues and strategies for elephant-shrews Conservation issues and strategies for elephant-shrews
The recommendations and implementation of the IUCN conservation plan for African Insectivora and elephant-shrews (Nicoll & Rathbun, 1990) are reviewed. Of the 33 species and subspecies of elephant-shrews, only six forest-dwelling taxa are threatened. Until additional status data are gathered, assessed, and published no changes in the IUCN threatened categories should be made: Rhynchocyon...

Native ranid frogs in California Native ranid frogs in California
Many recent declines and extinctions of native amphibians have occurred in certain parts of the world (Wake 1991; Wake and Morowitz 1991). All species of native true frogs have declined in the western United States over the past decade (Hayes and Jennings 1986). Most of these native amphibian declines can be directly attributed to habitat loss or modification, which is often exacerbated...

Foraging patterns of California sea otters as indicated by telemetry Foraging patterns of California sea otters as indicated by telemetry
Foraging behavior was studied in 38 sea otters (Enhydra lutris) implanted with radio transmitters. The observed foraging behavior of instrumented individuals was similar to that of uninstrumented otters observed in previous studies: dive duration varied with prey type but not with prey size, dive success was highest for small prey, and the length of surface intervals increased with prey...

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...

Bullfrogs: Introduced predators in southwestern wetlands Bullfrogs: Introduced predators in southwestern wetlands
In the American Southwest, much of the native fish fauna is facing extinction (Minckley and Deacon 1991); frogs in California (Fellers and Drost 1993) and frogs and garter snakes in Arizona (Schwalbe and Rosen 1988) are also in critical decline. Habitat destruction and introduced predators appear to be primary causes of native frog declines (Jennings and Hayes 1994), and habitat...
