Effects of body size on the survival and timing of emigration of newly metamorphosed Northern Red-legged frogs

Creator:

Chelgren, Nathan D.

Abstract:

The purpose of this study was to investigate the survival and movements of newly metamorphosed Northern Red-legged frogs (Rana aurora aurora) as they emigrated from two ephemeral breeding ponds. Quantifying survival and movement rates will be important to our understanding how changes to terrestrial and aquatic systems affect behavior and...

Habitat characteristics associated with abundance of band-tailed pigeons and use of mineral sites in the Pacific Northwest

Creator:

Overton, Cory T.

Abstract:

Index counts for the Pacific Coast race of the band-tailed pigeon (Columba fasciata monilis) have declined by -2% per year since survey efforts began in the 1950's and 60's. Mineral sites, important resources with high ion concentrations, are regularly visited by band-tailed pigeons which nest in surrounding forest lands. I...
