Description:

Abstract:: Seabirds may serve as sensitive indicators of marine conditions that impact Steller sea lions because their diet overlaps that of sea lions and other apex predators in the Gulf of Alaska and because seabird reproductive parameters are both easily monitored and responsive to food availability. In particular, seabirds are useful indicators of relative abundance and demographics of intermediate trophic levels because they eat small, young-of-year fishes which are ecologically important links in the food web but difficult to quantify in trawl and hydro-acoustic surveys. Therefore, we used seabirds as bio-indicators to monitor the relative abundance and distribution of forage fishes and other trophic intermediates of the Gulf of Alaska food web. Overall objectives were to
• determine seasonal diets and foraging areas of black-legged kittiwakes, glaucous-winged gulls and tufted puffins during breeding season
• monitor the numbers and breeding performance of offshore divers (tufted puffins, common murres), surface feeders (black-legged kittiwakes, glaucous-winged gulls), and nearshore divers (pigeon guillemots, cormorants).
• determine nestling diets and growth rates of tufted puffins, black-legged kittiwakes, glaucous- winged gulls, and pigeon guillemots.
We monitored dietary, reproductive, physiological and behavioral parameters of black-legged kittiwakes, glaucous-winged gulls and tufted puffins across their breeding season in 2001-2003. Seabirds exhibited remarkable similarity in the trends of predator-insensitive reproductive parameters thus allowing us to draw some general conclusions about marine foraging conditions in Chiniak Bay from 2001-2003. In 2001 evidence suggests that foraging conditions were consistently good across the entire breeding season for most colonies and species. Energy rich age 1+ sand lance dominated the diets and foraging took place primarily within the confines of the bay. In 2002, although foraging conditions appeared to be excellent early in the season, egg predators severely impacted the reproductive output of approximately 50% of kittiwake breeding colonies within the bay. Impaired nestling growth rates indicated that foraging conditions had declined markedly by the nestling period and were the poorest of any year of the study. Adult kittiwakes responded by devoting more time to foraging and by undertaking longer foraging trips that extended beyond the periphery of Chiniak Bay. Glaucous-winged gulls breed earlier in the season and thus exhibited excellent reproductive performance yet displayed decrease body condition and increase plasma corticosterone levels by late chick rearing suggestive of decreased forage availability in mid-summer. In 2003, egg laying was delayed by cool marine conditions in the spring and egg predation severely impacted most kittiwake colonies within the bay. Rapid nestling growth suggested excellent foraging conditions in 2003 while kittiwake parents provisioned nestlings on a diet of energy-rich capelin and, to a lesser degree, on lipid-poor YOY sand lance.
Purpose:: The Gulf Apex Predator-prey program (GAP) was initiated in1999 by University of Alaska Fairbanks faculty in Kodiak to address trophic-level questions of immediate biological and economic concern in the western Gulf of Alaska. The program’s goal is to document trophic relationships between Steller sea lions, their prey, competitors, and predators in the Kodiak region. Fundamental to the GAP program is the integration of distinct but related hypothesis-driven research projects. Although focused on sea lion concerns, GAP’s interrelated studies also broadly assess the degree of dietary overlap among Kodiak’s sympatric apex predators while exploring processes that drive populations of their prey within a dynamic marine environment. These studies overlap spatially and temporally, allowing synchronous collection of predator and prey data and synoptic assessment of their seasonal interactions. The Gulf Apex Predator-prey program is planned as a multiyear sampling effort that will allow monitoring inter-annual variability against which effects of human intervention may be compared. GAP investigators strive to facilitate synergistic linkage to related studies and efficiently broaden research beyond the scope of individual projects and have already fostered collaboration with fisheries and marine mammal researchers within the National Marine Fisheries Service (NMFS) Alaska Fisheries Science Center and Alaska Department of Fish and Game (ADFG).
