Surgical and immediate postrelease mortality of harlequin ducks (Histrionicus histrionicus) implanted with abdominal radio transmitters with percutaneous antennae Surgical and immediate postrelease mortality of harlequin ducks (Histrionicus histrionicus) implanted with abdominal radio transmitters with percutaneous antennae
Radiotelemetry is an essential tool in the study of free-ranging bird populations, and a variety of transmitter-attachment methods have been developed. A promising new method is abdominal implantation of a transmitter with a percutaneous antenna. Researchers using this technique should be concerned about and aware of mortality during surgery and during the immediate postrelease period...

Microsatellite diversity and conservation of a relic trout population: McCloud River redband trout Microsatellite diversity and conservation of a relic trout population: McCloud River redband trout
Rainbow trout native to the McCloud River, California, USA (Oncorhynchus mykiss stonei) are thought to represent a relic, nonanadromous trout adapted to harsh, fragmented environments. These fish, commonly named McCloud River ‘redband’ trout, survive in their most primitive form in a small, spring-fed stream, Sheepheaven Creek, in the upper McCloud River drainage. Turn-of-the-century...

Testing releasable GPS radiocollars on wolves and white-tailed deer Testing releasable GPS radiocollars on wolves and white-tailed deer
We tested prototype GPS collars on 8 free-ranging wolves (Canis lupus) and 3 white-tailed deer (Odocoileus virginianus) for varying periods between February and August 1997. We programmed the 920-gm collars to make a location attempt 6-96 times per day. The collars were designed to be remotely released from the animal and the data were then downloaded to a desktop computer. The collars...

Breeding of Steller's Eiders, Polysticta stelleri, on the Yukon-Kuskokwim Delta, Alaska Breeding of Steller's Eiders, Polysticta stelleri, on the Yukon-Kuskokwim Delta, Alaska
Historically, an unknown number of Steller's Elders nested along the outer coastal fringe of the Yukon-Kuskokwim Delta, Alaska, but no nests had been found since 1975. We located six nests from 1991-1998 and we conclude that Steller's Elders are still a regular breeder at low densities on the Yukon-Kuskokwim Delta.

Preliminary geologic map of the Chugach National Forest special study area, Alaska Preliminary geologic map of the Chugach National Forest special study area, Alaska
In 1990, both the U.S. Geological Survey and U.S. Bureau of Mines were contacted by the Chugach National Forest (CNF) for the purpose of providing mineral resource information for the CNF Master Plan during the planning period fiscal years 1991-1994. This information is to address the terms and requirements of the 1986 Settlement Agreement and to provide mineral and geologic information...

Alaska resource data file: McGrath quadrangle Alaska resource data file: McGrath quadrangle
The unnamed occurrence was investigated by the reporter in 1978 during a 1:63,360 scale geologic mapping effort for the Alaska Division of Geological and Geophysical Surveys in the McGrath quadrangle (Bundtzen and Laird, 1983). Two grab samples from the mineralized zone contained up to 222 ppm copper, 0.6 grams/tonne silver, and 100 ppm lead.

Effectiveness of streambank-stabilization techniques along the Kenai River, Alaska Effectiveness of streambank-stabilization techniques along the Kenai River, Alaska
The Kenai River in southcentral Alaska is the State's most popular sport fishery and an economically important salmon river that generates as much as $70 million annually. Boatwake-induced streambank erosion and the associated damage to riparian and riverine habitat present a potential threat to this fishery. Bank-stabilization techniques commonly in use along the Kenai River were...

Sustainable fisheries management: Pacific salmon Sustainable fisheries management: Pacific salmon
What has happened to the salmon resource in the Pacific Northwest? Who is responsible and what can be done to reverse the decline in salmon populations? The responsibly falls on everyone involved - fishermen, resource managers and concerned citizens alike - to take the steps necessary to ensure that salmon populations make a full recovery. This collection of papers examines the state of...
