Year: 1992

Author(s): Kees Vermeer

Type: Proceedings

Description:
"This book presents the proceedings of a symposium on the ecology, status and conservation of marine and shoreline birds on the west coast of Vancouver Island.

Title: The Clayoquot Biosphere Project: Natural History Study

Year: 1992

Author(s): Clayoquot Biosphere Project

Type: Other

Description:
The natural history program of the Clayoquot Biosphere Project is based on the nearly lost art of natural history observation. The key ingredients are enthusiastic observers, extensive time in the field, and rigorous observations of nature. This study, combined with related education programs, will help re-develop an awareness and understanding of the day-to-day natural events occurring around us in Clayoquot Sound. This work will also provide the necessary foundation for vital ecological and behavioural studies in the intact temperate rainforest ecosystem.

Title: Zooplankton on the west coast of Vancouver Island: distribution and availability to marine birds

Year: 1991

Author(s): David Mackas, Canadian Wildlife Service; Moira Galbraith, Canadian Wildlife Service

Type: Proceedings

Description:
Abstract: The outer coast of Vancouver Island is biologically highly productive because of large summer inputs of upwelled nutrients and resulting dense phytoplankton blooms. The resident zooplankton populations are well fed from spring through autumn; their seasonal cycle and spatial distribution are set largely by advective patterns and bathymetry. pp15-21.

Title: Factors affecting the distribution of kelp and its importance as a food source.

Year: 1991

Author(s): Robert DeWreede

Type: Proceedings

Description:
abstract: Kelp beds form a major habitat in many near-shore marine sites in British Columbia. The abundance and distribution of kelps are determined in part by such factors as salinity, light and temperature and by herbivores, such as sea urchins and limpets. Sea otters Enhydra lutris influence kelp distribution by consuming urchins. Together these factors determine the age (and hence size and stage) and structure of kelp stands. Birds are predators of organisms that live in kelp beds, but almost nothing is known of kelp-bird interactions in British Columbia. pp37-40.

Title: Seasonal abundance and biomass of birds in eelgrass habitats in Browning Passage on the west coast of Vancouver Island.

Year: 1991

Author(s): Rob Butler, Canadian Wildlife Service; Adrian Dorst; Mark Hobson

Type: Proceedings

Description:
abstract: The Western Sandpiper Calidris mauri was the most abundant bird species seen in Browning Passage over a one year period and was most plentiful in April and August. Shorebirds as a group made up less than 2 percent of the annual bird biomass. Geese, diving ducks, and dabbling ducks made up nearly 34 percent of all birds seen through the year and nearly 80 percent of the bird biomass. They were least abundant in summer. pp109-113.

Title: Environmental disturbance and conservation of marine and shoreline birds on the west coast of Vancouver Island.

Year: 1991

Author(s): Kees Vermeer; Ken Morgan; Robert Butler

Type: Proceedings

Description:
abstract: Loss of habitat and oiling of birds represents two major threats to marine and shoreline bird populations on the west coast of Vancouver Island. Logging of mature and old-growth forests has led to the destruction of the nesting habitat of Marbled Murrelets Brachyramphus marmoratus, whereas industrial development of estuaries, mudflats and spawning grounds of Pacific herring Clupea harengus pallasi has diminished feeding habitats for other marine and shoreline birds. Fisheries operations, human disturbance of colonies, and introduced predators, notably racoon Procyon lotot and mink Mustela vison, have impacted upon local populations. Management actions and research needs to mitigate these threats are addressed. pp129-133.

Title: Geographic and local variation in nesting phenology and clutch size of the black oystercatcher

Year: 1991

Author(s): Marie-Aude L'Hyver; Edward H. Miller

Type: Journal Article

Description:
The Black Oystercatcher (Haematopus bachmani) is a year-round resident with an extensive range from southern Californi to Alasak. Because of the size of this range and its simple, nearly linerar shape, we hypothesized that the species would exhibit adaptive geographic variation in nesting phenology and clutch size. Museum egg collections provided information for the entire nesting range, while field observations on about 40 breeding pairs on Cleland Island, BC, providing information on local variation.

Title: Latitudinal Clines: A trade-off between egg number and size in pacific salmon

Year: 1990

Author(s): Ian A. Fleming; Mart R. Gross

Type: Journal Article

Description:
The latitudinal variation in clutch size found in many animal species, including Pacific salmon, has been an enigmatic problem in ecology. We analyze egg number and egg size of 17 populations of coho salmon (Oncorhynchus Kisutch)distributed over a latitudinal gradient in North America. These populations have a significant latitudinal increase in their egg number. But this increase is accompanied by a significant latitudinal decrease in their egg size. The total biomass of eggs produced also declines with latitude.

Title: Factors affecting colony attendance by Ancient Murrelets (Synthliboramphus antiquus)

Year: 1990

Author(s): Ian Jones, University of Toronto; Anthony Gaston; Bruce Falls

Type: Journal Article

Description:
We studied factors influencing variation in nightly levels of activity (birds arriving and vocalizing) and numbers of birds staging offshore at a colony of Ancient Murrelets at Reef Island, British Columbia, during 1984, 1985, and 1986. Activity was restricted to the hours of darkness and extremely variable in magnitude from night to night. The rate of entry into burrows tended to decease, and the amount of vocalization and numbers of birds at the staging area increased during the nesting season. We detected an underlying 4-day cyclical pattern of attendance. Nightly variability of activity at the colony was effected by moonlight and weather conditions. Since activity, particularly vocalization, was reduced on moonlight nights, we suggest that nocturnal colony attendance is a strategy to avoid diurnal predators in this species. The largest numbers of birds were present and vocalizing at the colony on calm moonless nights. Weather conditions explained a substantial proportion of the night to night variability in murrelt activity. Among weather variables, wind speed had the most consistent effect and was particularly important in 1985. Both short/term, i.e., of a particular night, and long-term, i.e., over the previous 3 days, conditions influenced activity. Our observations suggest that direct weather effects at the colony may be more important than weather effects related to foraging conditions. Interyear differences in activity may have resulted from the interaction of weather and general foraging conditions.
