Effects of spring environment on nesting phenology and clutch size of Black Brant Effects of spring environment on nesting phenology and clutch size of Black Brant
We studied the effects of timing of spring snowmelt on nesting phenology, nest site selection, and clutch size of Black Brant (Branta bernicla nigricans) breeding at the Tutakoke river colony, Yukon-Kuskokwim Delta, Alaska. In late springs, brant nested later: however, time between peak arrival at Tutakoke and nest initiation (6 to 12 days) was similar in early and late springs. Nest...

Food of Flesh-footed shearwaters Puffinus carneipes associated with high-seas driftnets in the central North Pacific Ocean Food of Flesh-footed shearwaters Puffinus carneipes associated with high-seas driftnets in the central North Pacific Ocean
We examined digestive tract contents and stable nitrogen isotope ratios in breast muscles of Flesh-footed Shearwaters Puffinus carneipes associated with high-seas driftnet fisheries in the central North Pacific Ocean. Small fish, Lanternfish (Myctophidae) and Pacific Saury Cololabis saira, were the principal prey found in the digestive tracts. Pieces of unidentified fish, possibly...

Distribution of autumn-staging Lesser Snow Geese on the northeast coastal plain of Alaska Distribution of autumn-staging Lesser Snow Geese on the northeast coastal plain of Alaska
We conducted aerial surveys of Lesser Snow Geese (Chen caerulescens caerulescens) during autumn staging on the coastal plain of the Arctic National Wildlife Refuge (ANWR) in northeast Alaska from late August through September, 1982 - 1993. We evaluated numbers and distribution of Snow Geese that staged on the ANWR, compared abundance of birds among 5 x 5-km cells used frequently (5 - 8...

Distribution and stability of eelgrass beds at Izembek Lagoon, Alaska Distribution and stability of eelgrass beds at Izembek Lagoon, Alaska
Spatial change in eelgrass meadows, Zostera marina L., was assessed between 1978 and 1987 and between 1987 and 1995 at Izembek Lagoon, Alaska. Change in total extent was evaluated through a map to map comparison of data interpreted from a 1978 Landsat multi-spectral scanner image and 1987 black and white aerial photographs. A ground survey in 1995 was used to assess spatial change from...

Hematological and plasma biochemical reference ranges of Alaskan seabirds: Their ecological significance and clinical importance Hematological and plasma biochemical reference ranges of Alaskan seabirds: Their ecological significance and clinical importance
Blood was analyzed from 151 pelagic marine birds to establish reference ranges for hematological and plasma biochemical parameters from healthy, wild populations of Pacific seabirds. Of the 13 species examined, 9 were from the Family Alcidae (N = 122 individuals) and the remainder (N = 29) from the Families Phalacrocoracidae, Laridae, and Procellariidae. Three of 8 hematological...

Water Resources Data for Alaska, Water Year 1996 Water Resources Data for Alaska, Water Year 1996
Water resources data for the 1996 water year for Alaska consist of records of stage, discharge, and water quality of streams; stages of lakes; and water levels and water quality of ground water. This volume contains records for water discharge at 85 gaging stations; stage or contents only at 5 gaging stations; water quality at 19 gaging stations; and water levels for 49 observation wells...
