Journal ArticleDOI
Modeling and field-testing of Ovenbird (Seiurus aurocapillus) responses to boreal forest dissection by energy sector development at multiple spatial scales
TL;DR: In this article, a spatially explicit model was developed to test how bird abundance might change in response to increasing seismic line density if individuals use seismic lines as territory boundaries or actively avoid these edges.
Journal ArticleDOI
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
TL;DR: Stable isotope analysis of tissues of Keen's mice and Townsend's voles and a subset of prey items at Triangle Island allowed us to investigate the importance of seabird prey in rodent diets in a system where seabirds and non-introduced rodents occur sympatrically.
Journal ArticleDOI
Quantifying dietary pathways of proteins and lipids to tissues of a marine predator
Seth G. Cherry,Andrew E. Derocher,Keith A. Hobson,Ian Stirling,Ian Stirling,Gregory W. Thiemann,Gregory W. Thiemann +6 more
TL;DR: The results indicate using stable isotopes to infer dietary inputs when proportions of macromolecules fluctuate amongst food sources requires the sampling and analysis of multiple tissues representing distinctmacromolecular metabolic pathways.
Journal ArticleDOI
Influence of nest-site vegetation and predator community on the success of artificial songbird nests
TL;DR: The results suggest that nest visibility is a major factor influencing risk of predation, but the relative importance of concealment varies according to the types of predators and their behavior.
Journal ArticleDOI
Stable carbon and hydrogen isotopes from bat guano in the Grand Canyon, USA, reveal Younger Dryas and 8.2 ka events
Christopher M. Wurster,William P. Patterson,Donald A. McFarlane,Leonard I. Wassenaar,Keith A. Hobson,Nancy Beavan Athfield,Michael I. Bird +6 more
TL;DR: The authors inferred climate change through the Pleistocene-Holocene transition from δ 13 C and δD values of bat guano deposited from 14.5 to 6.5 ka (calendar ka) in Bat Cave, Grand Canyon, Arizona.
