Title: Role of nest raiding and egg predation in regulating population density of threespine sticklebacks (Gasterosteus aculeatus) in a coastal British Columbia lake

Year: 1989

Author(s): K. D. Hyatt; N. H. Ringler

Type: Journal Article

Description:
The consequences of nest raiding and egg predation for population regulation of sticklebacks (Gasterosteus aculeatus) were studied in a British Columbia coastal lake. Stickleback eggs were present in the stomachs of 23 and 11% of all sticklebacks sampled in the field in 1982 and 1985 respectively. On average, males consumed more eggs than females did. Seasonal egg consumption increased with increases in stickleback density in breeding colonies. Our evidence suggests that both nest raiding and egg cannibalism are important in limiting the production of stickleback fry as population density increases in scattered, lakeshore, breeding colonies of Kennedy Lake.

Title: Fish Survey of S.E. Clayoquot Sound Streams, Vancouver Island

Year: 1989

Author(s): T.G. Brown; B.C. Anderson; J.C. Scrivener; I.V. Williams

Type: Report (published)

Description:
Minnow traps were used to capture juvenile salmonids from six locations in each of the twenty-three S.E. Clayoquot Sound Streams. At each location the environmental features were noted, recorded, and scales were obtained for salmonid age determination. Juvenile coho catch/effort, mean length of one stream surveyed. The mean catch at each location was correlated to various environmental features such as: dominant biogeoclimatic variant, gradient, stream order, stream orientation and stream location.

Title: Watershed Data Base: Clayoquot Sound, Vancouver Island

Year: 1987

Author(s): T.G. Brown; I.V. Williams; R.T.E. Pulfer

Type: Report (published)

Description:
Catalogue of 34 Clayoquot Sound streams which provides information on: location, physical characteristics, forest cover, tenure status, biogeoclimatic variants and relative abundance of salmonid species. This catalogue was designed to provide a single source of the information considered essential to initial practical study designs for future fish/forestry research.

Title: Response of Attached Algae to Whole-Lake Fertilization Experiments in Five British Columbia Coastal Lakes

Year: 1978

Author(s): K. R. S. Shortreed; J. G. Stockner

Type: Report (unpublished)

Description:
Characteristics of attached algal growth were monitored in six oligotrophic lakes in south coastal B.C. using Plexiglas plates as a substrate. Nitrate and phosphate were added weekly to areas within five of the lakes. The additions produced attached algal biomass within fertilized areas up to an order magnitude greater than biomass outside these areas. Diatoms were dominant, principally Achnanthes minutissima, Fragilaria vaucheriae, Tabellaria spp., and Eunotia spp. The most common non-diatom alga was Mougeotia spp. Species composition was not measurably altered by fertilization in any of the five lakes. Nitrate and phosphate were utilized rapidly and concentrations within fertilized areas were similar to those without. Although N:P ratios occasionally dropped 5:1, blue-green algae were of little importance. Clayoquot Arm in unfertilized Kennedy Lake had mean chlorophyll a values lower than previously recorded for any biological system.

Title: A photoduplicate file for British Columbia vertebrate records.

Year: 1971

Author(s): R. Wayne Campbell; David Stirling

Type: Journal Article

Description:
During 1970, colour slides and black and white photographs were solicited from naturalists and scientists throughout British Columbia to document the occurrence of rare or previously unrecorded vertebrates in the Province. Forty-one contributors submitted 150 photographs, of which 11 documented additions to the known vertebrate fauna of British Columbia. A centre of deposition for photographic records of vertebrates in British Columbia has now been established and set up in the Vertebrate Museum at the University of British Columbia in Vancouver. Examples of photographs acceptable are listed under seven general headings.

Author(s): David Pitt-Brooke; Clayoquot Biosphere Project

Type: Journal Article

Description:
The Clayoquot Valley Natural History program was intended to generate year-round observations of natural history events across a broad range of habitats in the Clayoquot River Valley, in order to provide regular, longer-term monitoring of the watershed.

Title: Discover Long Beach Model Forest

Year: n.d.

Type: Public Relations Material

Description:
Introduction: Welcome to the Long Beach Model Forest. This handbook will introduce you to the environment and communities of the Long Beach Model Forest and will acquaint you with a few of the many programs and projects supported by the Long Beach Model Forest Society (LBMFS). The emphasis at the LBMFS is on communities and community initiatives. LBMFS is a catalyst for change. We provide information and a forum for discussion. We encourage partnerships. We help to fund worthwhile projects in a biological or socio-economic research and projects that implement and demonstrate new approaches to sustainable forest practices.

Title: Coarse woody debris n a forested watershed on the west coast of Vancouver Island, British Columbia

Year: n.d.

Author(s): Rodney J. Keenan; Alex Inselberg

Type: Report (unpublished)

Description:
(from Introduction) There were two objectives in this study. The first was to estimate volume and mass of downed coarse woody debris occurring in different forest ecosystems in the Tofino Creek watershed. The second was to determine the variability in volute estimates of coarse woody debris with different sampling intensities. The latter objective was aimed at providing a guide for the degree of sampling necessary for reasonably precise estimates of the volume of coarse woody debris for future surveys in this area.
