Tracking the spring migration of a bar-headed goose (Anser indicus) across the Himalaya with satellite telemetry Tracking the spring migration of a bar-headed goose (Anser indicus) across the Himalaya with satellite telemetry

Soil-food-chain-pesticide wildlife relationships were investigated to learn the concentration of pesticide residues present in soils, macro-invertebrates, vertebrates, and seeds as a result of annual applications of aldrin at recommended rates for pest control. Two central Missouri cornfields treated witb aldrin at 1 lb/acre, for 16 and 15 of the past 17 years, were selected for study...

Elk-effects vegetation monitoring program for Tomales Point Elk Range, Point Reyes National Seashore, California Elk-effects vegetation monitoring program for Tomales Point Elk Range, Point Reyes National Seashore, California

The monitoring program for elk effects on Tomales Point vegetation is designed to provide information on how tule elk grazing affects plant communities and rare species. The basic objective of the program is to show whether the elk are driving the vegetation into an unacceptable state by their grazing. The expectation is that as elk numbers increase, grazing pressure will increase too...

Activities and preliminary results of nearshore benthic habitat mapping in southern California, 1998 Activities and preliminary results of nearshore benthic habitat mapping in southern California, 1998

The nearshore benthic habitat of the Santa Barbara coast and Channel Islands supports a diversity of marine life that are commercially, recreationally, and intrinsically valuable. Some of these resources are known to be endangered including a variety of rockfish and the White Abalone. State and National agencies have been mandated to preserve and enhance these resources and require...

Postflood persistence and recolonization of endangered tidewater goby populations Postflood persistence and recolonization of endangered tidewater goby populations

Before-and-after surveys at several southern California sites indicated that populations of endangered tidewater goby Eucyclogobius newberryi persisted through heavy flooding in 1995. This was contrary to our expectations that flooding might have led to extirpation in some smaller wetlands. There was also no significant change in tidewater goby density before and after the flooding...

Interactions between northern elephant seals and vehicles near Point Piedras Blancas, California Interactions between northern elephant seals and vehicles near Point Piedras Blancas, California

Northern elephant seals, Mirounga angustirostris, were nearly extirpated in the late 19th and early 20th centuries. However, they have recovered to the point where they are now locally abundant (Stewart e t al. 1994). Stimulated by the report of human/northern elephant seal interactions in Baja California Sur (Webster and Baird 1998), we report here on an unusual terrestrial example of...

Results of the 1999 survey of the reintroduced sea otter population in Washington state Results of the 1999 survey of the reintroduced sea otter population in Washington state

Fifty-nine sea otters were released off the west coast of the Olympic Peninsula of Washington State during the summers of 1969 and 1970; all had been translocated from Amchitka Island, Alaska. In 1970, 30 otters were released. Surveys to assess the results of this translocation began in 1977. Up to 1989, the population has grown at near the maximum rate of increase (rmax) for sea otter...
