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,

Ellis Island ER #134 Overview: Biological and Physical

ORIGINAL PURPOSE To protect a vulnerable gull nesting colony for research purposes. Physical: Fraser Lake, about 50 km2 in size, drains eastward into the Nechako River. Ellis Island, 600 m from its southern shore, is low and egg-shaped. Much of the surface of this heavily glaciated island is bare rock; where soils are developed they

Yellowpoint Bog ER #139 Overview: Biological and Physical

ORIGINAL PURPOSE To protect a highly diverse mosaic of ecosystem types from aquatic, peat bog and forest to dry-site ecosystems. Physical: The reserve comprises gently undulating lowlands formed by glacially scoured rocks of the cretaceous Nanaimo Formation. For the most part the cover of surficial deposits and soils on the NW-SE trending, rounded ridges is
