Testing for individual variation in breeding success

I measured the breeding success of Northern Fulmars (Fulmarus glacialis) in 6 consecutive years at a colony in the Semidi Islands, western Gulf of Alaska (56°N, 156°W). I tabulated the frequency distribution of the number of years successful for a sample of 224 nest sites at which breeding occurred in all 6 yr. A consistently higher probability of...

Comparison of five techniques for the detection of Renibacterium salmoninarum in adult coho salmon.

Samples of kidney, spleen, coelomic fluid, and blood from 56 sexually mature coho salmon Oncorhynchus kisutch were examined for infection by Renibacterium salmoninarum by five methods. The overall prevalence (all sample types combined) of R. salmoninarum in the fish was 100% by the enzyme-linked immunosorbent assay, 86% by the combined results of...

Infectious hematopoietic necrosis virus detected by separation and incubation of cells from salmonid cavity fluid.

Infectious hematopoietic necrosis (IHN) virus is usually detected by inoculating susceptible cell cultures with cavity ("ovarian") fluid (CF) from spawning females. We identified additional adult carriers of virus in spawning populations of steelhead trout (Salmo gairdneri) and sockeye salmon (Oncorhynchus nerka) by collecting nonerythrocytic...

Enzyme-linked immunosorbent assay for a soluble antigen of Renibacterium salmoninarum, the causative agent for salmonid bacterial kidney disease

A double-antibody enzyme-linked immunosorbent assay (ELISA) for detection of a soluble fraction of Renibacterium salmoninarum was developed from components extracted from the supernatant of an R. salmoninarum broth culture. The Costar® Serocluster™ EIA microplate gave the highest absorbance and signal-to-noise ratios among seven types tested....

Tables showing analyses of semiquantitative spectrometry and atomic-absorption spectrophotometry of rock samples collected in the Ugashik, Bristol Bay, and western part of the Karluk quadrangles, Alaska

The accompanying tables list chemical analyses of 337 rock samples that were collected in 1979, 1980, and 1981 in conjunction with geologic mapping in the Ugashik, Bristol Bay, and part of Karluk quadrangles. This work was conducted under the auspices of the Alaska Mineral Resource Assessment Program (AMRAP). This report is to accompany Wilson and...

Adult survival and productivity of Northern Fulmars in Alaska

The population dynamics of Northern Fulmars (Fulmarus glacialis) were studied at the Semidi Islands in the western Gulf of Alaska. Fulmars occurred in a broad range of color phases, and annual survival was estimated from the return of birds in the rarer plumage classes. A raw estimate of mean annual survival over a 5-year period was 0.963, but a...

Aggressive encounters between tundra swans and greater white-fronted geese during brood rearing

Interspecific aggression in waterfowl (Anatidae) is relatively common (McKinney 1965; Kear 1972; Savard 1982, 1984), but interactions leading to mortality of one of the combatants are rarely-observed in the wild. A recent debate (Livezey and Humphrey 1985a, 1985b; Nuechterlein and Storer 1985a, 1985b; Murray 1985) has centered on the proximate and...

An inexpensive device for recording animal behavior

Recording animal behavior is tedious and time consuming when behaviors are recorded on tape and transcribed to data sheets. Data loggers circumvent these problems, but can be prohibitively expensive and may require extensive programming (see Hensler et al. [1986]). I describe an inexpensive, efficient alternative for recording behavioral...

Autumn staging of cackling Canada geese on the Alaska Peninsula

Cackling Canada Geese Branta canadensis minima undergo a long (2,800 km) migration between their autumn staging areas on the Alaska Peninsula and wintering areas in Oregon and California. Adults and young lost an average of 543 g during this migratory flight. Weight gains between fledging and autumn migration are essential for the successful...

Common Murre (Uria aalge) attendance patterns at Cape St. Mary's, Newfoundland

Attendance patterns of common murres (Uria aalge) at Cape St. Mary's, Newfoundland, were observed during hatching to post-fledging periods of 1980 to 1984. Six study plots on breeding ledges (ca. 450 birds total) and a "club" on the water were monitored for seasonal fluctuations in numbers attending. Attendance on ledges was similar between years...

Copulation and mate guarding in the Northern Fulmar

I studied the timing and frequency of copulation in mated pairs and the occurrence of extra-pair copulation (EPC) among Northern Fulmars (Fulmarus glacialis) for 2 yr. Copulation peaked 24 days before laying, a few days before females departed on a prelaying exodus of about 3 weeks. I estimated that females were inseminated at least 34 times each...

Cumulative impacts of oil fields on northern Alaskan landscapes

Proposed further developments on Alaska's Arctic Coastal Plain raise questions about cumulative effects on arctic tundra ecosystems of development of multiple large oil fields. Maps of historical changes to the Prudhoe Bay Oil Field show indirect impacts can lag behind planned developments by many years and the total area eventually disturbed can...
