Preliminary volcano-hazard assessment for Iliamna Volcano, Alaska Preliminary volcano-hazard assessment for Iliamna Volcano, Alaska
Iliamna Volcano is a 3,053-meter-high, ice- and snow-covered stratovolcano in the southwestern Cook Inlet region about 225 kilometers southwest of Anchorage and about 100 kilometers northwest of Homer. Historical eruptions of Iliamna Volcano have not been positively documented; however, the volcano regularly emits steam and gas, and small, shallow earthquakes are often detected beneath...

Subcutaneous implantation of satellite transmitters with percutaneous antennae into male polar bears (Ursus maritimus) Subcutaneous implantation of satellite transmitters with percutaneous antennae into male polar bears (Ursus maritimus)
Male polar bears (Ursus maritimus) have not been successfully instrumented with satellite transmitters because they readily shed collar-mounted transmitters. Seven male polar bears were captured on the pack ice off the northern coast of Alaska and surgically implanted with satellite transmitters with percutaneous antennae into the subcutaneous space of the dorsal cervical region...

Data for periphyton and water samples collected from the south Florida ecosystem, 1995 and 1996 Data for periphyton and water samples collected from the south Florida ecosystem, 1995 and 1996
This report presents data for samples of periphyton and water collected in 1995 and 1996 from Water Conservation Areas, the Big Cypress National Preserve, and the Everglades National Park in south Florida. Periphyton samples were analyzed for concentrations of total mercury, methylmercury, nitrogen, phosphorus, organic carbon, and inorganic carbon . Water-column samples collected on the...

Leucocytozoon simondi in Emperor Geese from the Yukon-Kuskokwim Delta in Alaska Leucocytozoon simondi in Emperor Geese from the Yukon-Kuskokwim Delta in Alaska
We surveyed Emperor Geese (Chen canagica) in western Alaska for avian hematozoa. Blood smears were collected from 134 adults and goslings in late July 1996, on their breeding grounds on the Yukon-Kuskokwim Delta. One of 134 (0.7%) Emperor Geese harbored Leucocytozoon simondi, representing a new host record for this parasite. No other hematozoa were detected. This is one of few reports of...

Settlement rate of lead shot in tundra wetlands Settlement rate of lead shot in tundra wetlands
Several species of breeding waterfowl have been shown to be exposed to lead shot on the Yukon-Kuskokwim (Y-K) Delta, Alaska. I 'seeded' experimental plots with number 4 lead shot to determine the settlement rate of shot in wetland types commonly used by foraging waterfowl. I resampled plots for 3 years, using a suction dredge to remove sediment in 4-cm layers. There was no consistent...

Selection of forage-fish schools by Murrelets and Tufted Puffins in Prince William Sound, Alaska Selection of forage-fish schools by Murrelets and Tufted Puffins in Prince William Sound, Alaska
We collected hydroacoustic and bird-observation data simultaneously along transects in three areas in Prince William Sound, Alaska, 21 July-11 August 1995. The probability of the association of fish schools with Marbled Murrelets (Brachyramphus marmoratus) and Tufted Puffins (Fratercula cirrhata) was determined through the use of resource selection functions based on logistic regression...

Certainty of paternity and paternal investment in eastern bluebirds and tree swallows Certainty of paternity and paternal investment in eastern bluebirds and tree swallows
Extra-pair paternity is common in many socially monogamous passerine birds with biparental care. Thus, males often invest in offspring to which they are not related. Models of optimal parental investment predict that, under certain assumptions, males should lower their investment in response to reduced certainty of paternity. We attempted to reduce certainty of paternity experimentally...
