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

Carina Gjerdrum*†, Anne M. J. Valle ́ e‡§, Colleen Cassady St. Clair*¶ Anomalously warm sea-surface temperatures (SSTs) are associated with interannual and decadal variability as well as with long-term climate changes indicative of global warming. Such oscillations could precipitate changes in a variety of oceanic processes to affect marine species worldwide. As global temperatures continue

Anne Vallee (Triangle  Island) Ecological Reserve : Purpose Statement Ecological reserves are areas selected to preserve representative and special natural ecosystems, plant and animal species, features and phenomena. The key goal of ecological reserves is to contribute to the maintenance of biological diversity and the protection of genetic materials. All consumptive resource uses and the use of motorized

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,

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

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
