An assessment of abundance and growth of the sea otter population (Enhydra lutris) in British Columbia

An assessment of abundance and growth of the sea otter population (Enhydra lutris) in British Columbia By Nichol, L.M., J.C. Watson, G.M. Ellis, J.K.B. Ford Abstract Sea otters were re-introduced to British Columbia from Alaska between 1969 and 1972. The first population count was made in 1977. Since 1988, field surveys have been undertaken using small boat or helicopter,

Forage fish quality and implications for rhinoceros auklet chick growth.

Beaubier, J.  2005.  Thesis Proposal Summary.  Forage fish quality and implications for rhinoceros auklet chick growth.  University of British Columbia. Rhinoceros auklets breeding at Triangle Island provision their chicks with 4 main species of forage fish: pacific saury (Cololabis saira), pacific sand lance (Ammodytes hexapterus), juvenile rockfish (Sebastes spp.), and juvenile salmon (Oncorhynchus spp.), supplemented with a variety of other, less utilized species.  The relative composition of each species

MSc thesis, Centre for Wildlife Ecology, Department of Biological Sciences, Simon Fraser University, Burnaby, BC. 74 pp. Tufted puffins (Fratercula cirrhata) are unusual among seabirds in that they bear multiple colourful ornaments during the breeding season. They

Parental Provisioning and Nestling Departure Decisions: A Supplementary Feeding Experiment inTufted Puffins (Fratercula cirrhatta) on Triangle Island, BC

Carina Gjerrum’s Thesis published in The Auk 121(2):463-472. 2004 Abstract I used a supplemental feeding experiment to determine whether adult Tufted Puffins (Fratercula cirrhata) would decrease provisioning effort in response to a reduction in nestling nutritional requirements, and to investigate the relationship between parental provisioning effort and timing of fledging. As predicted, parents of the

Southern Vancouver Island Marine Waters and Seabird Islands Important bird Areas Conservation Plan

Barry Booth , Community Conservation Planner Canadian Nature Federation , Federation of BC Naturalists, Wild Bird Trust of BC , IBA program. The issue The east coast of southern Vancouver Island and associated Gulf Islands represent extremely important habitat for a wide variety of birds, during the breeding and non-breeding seasons. Recently, several Important Bird Areas were

Short visits reveal consistent patterns of interyear and intercolony variation in seabird nestling diet and performance

D.F. Bertram, T. Golumbia, G.K. Davoren, A. Harfenist, and J. Brown  Abstract: To investigate the utility of short visits to seabird colonies to gauge nestling growth performance and diet, in 4 consecutive years (1995–1998) we measured nestling development and diet of Rhinoceros Auklets (Cerorhinca monocerata) at three colonies in British Columbia: Seabird Rocks, Triangle Island,

Evaluating the Effects of Three Forms of Marine Reserve on Northern Abalone Populations in British Columbia, Canada

Author S. Scott Wallace Article first published online: 24 DEC 2001, Conservation Biology Volume 13, Issue 4, pages 882–887, August 1999 DOI: 10.1046/j.1523-1739.1999.98117.x Abstract: Marine reserves have been suggested as tools for assisting the management of fisheries by protecting vulnerable marine species from overexploitation. Although there is a theoretical basis for believing that marine reserves may serve as management tools,

Survival rates of Cassin’s and Rhinoceros Auklets at Triangle Island, British Columbia.

Bertram, D. F., I. L. Jones, E. C. Cooch, H. A. Knechtel, and F. Cooke. 2000. Abstract: We estimated survival of Cassin’s Auklet (Ptychoramphus aleuticus) and Rhinoceros Auklet (Cerorhinca monocerata) from recapture rates during 1994-1997. For both species, a two “age”-class model provided the best fit. Estimates of local adult survival were significantly lower for

Predation on seabird eggs by Keen’s mice (Peromyscus keeni): using stable isotopes to decipher the diet of a terrestrial omnivore on a remote offshore island

M.C. Drever, L.K. Blight, K.A. Hobson, and D.F. Bertram Abstract: We used stable isotope techniques to analyze tissues of Keen’s mice (Peromyscus keeni) and Townsend’s voles (Microtus townsendii cowani) and a subset of prey items at Triangle Island, British Columbia, western Canada’s largest seabird colony. Isotope analysis allowed us to investigate the importance of seabird
