Breeding biology of Pacific white-fronted geese

Nesting ecology of Pacific white-fronted geese (Anser albifrons frontalis) was studied on a 9.9-km2 area on the Yukon-Kuskokwim (Y-K) Delta, Alaska, during 1977-79. Availability of nesting habitat varied considerably among years because of differences in time of snow- and icemelt. Mean clutch size was 3.7 eggs in the late spring thaw year and 5.2...

Composition and energy contents of mature inshore spawning capelin (Mallotus villosus): Implications for seabird predators

1. Lipid levels of capelin are highest in late fall and lowest during the summer spawning season; protein levels are constant at 13–14% body wt throughout the year.2. Ovid females contained significantly more lipid and protein and less water and had higher energy densities than males and spent females.3. Surgically-removed egg masses made up 34.2...

Dietary changes and poor reproductive performance in Glaucous-winged Gulls

The breeding phenology of Glaucous-winged Gulls (Larus glaucescens) on Squab Island, Aialik Bay, Alaska in 1979 was identical to that in 1980, but clutch sizes and later reproductive performance differed markedly. In 1979, clutch sizes were small, but chick growth rates and survivorship were high. In contrast, clutch sizes were large in 1980, but...

Nestling diet and feeding rates of rhinoceros auklets in Alaska

Food brought to nestling Rhinoceros Auklets (Cerorhinca monocerata) was sampled by applying tape or cloth muzzles to the chicks and collecting the uningested food from the burrow daily. Limited data were also gathered for Tufted and Horned puffins (Fratercula cirrhata and F. corniculata). Auklet chicks received an average of 34.1 g of food per...

Offset of Tertiary arcs on the Alaska Peninsula: A section in Geological Survey research, fiscal year 1981

Geologic mapping and potassium-argon dating by R. L. Detterman, F. H. Wilson, J. E. Case, and Nora Shew in the Ugashik and western part of the Karluk quadrangles have shown that the Eocene and Oligocene volcanic arc continues into these quadrangles from the south in the Chignik and Sutwik Island quadrangles. Surface exposures of the arc extend...

The Jeanie Point complex revisited

The so-called Jeanie Point complex is a distinctive package of rocks within the Orca Group, a Tertiary turbidite sequence. The rocks crop out on the southeast coast of Montague Island, Prince William Sound, approximately 3 km northeast of Jeanie Point (loc. 7, fig. 44). These rocks consist dominantly of fine-grained limestone and lesser amounts of...

Titre distribution patterns of infectious haematopoietic necrosis virus in ovarian fluids of hatchery and feral salmon populations

Infectious haematopoietic mecrosis virus (IHNV) is enzootic in virtually all populations of sockeye salmon, Oncorhynchus nerka (Walbaum), and in populations of chinook salmon, O. tshawytscha (Walbaum), of the Sacramento River drainage in California. This disease is an obstacle in hatcheries using brood stocks from these populations. However,...

Effect of loading density of sockeye salmon, Oncorhynchus nerka (Walbaum), eggs in incubation boxes on mortality caused by infectious haematopoietic necrosis

Infectious haematopoietic necrosis (IHN) can cause massive mortalities of sockeye salmon, Oncorhynchus nerka (Walbaum), cultured in hatcheries. One method of enhancing sockeye salmon populations is to use a streamside egg incubation box from which the fry are automatically released into the stream as they emerge from the gravel. In this system,...
