Understanding and predicting the distribution of organisms in heterogeneous environments lies at the heart of ecology, and the theory of density-dependent habitat selection (DDHS) provides ecologists with an inferential framework linking evolution and population dynamics. Current theory does not allow for temporal variation in habitat quality, a serious limitation when confronted with real ecol...

Habitat selection during the breeding season has important consequences for reproductive success and, in seasonal and heterogeneous environments, most likely occurs on several temporal and spatial scales. I examined several possible topographical, substrate and vegetation, as well as anthropological effects on snowy plover (Charadrius alexandrinus) habitat selection across pre-breeding and bree...

We investigated daily and annual variation in the marine habitat selection of marbled murrelets Brachyramphus marmoratus (Alcidae) in the nearshore California Current System at scales of 10 to 100 km of coastline. We addressed 2 general questions: (1) how do murrelets select habitat while facing dramatic and often rapid variation in oceanographic conditions and prey availability; and (2) does s...

Understanding habitat selection of gray foxes (Urocyon cinereoargenteus) is essential to evaluate their potential response to changes in land use and predator communities. Few studies have evaluated temporal habitat selection or explicitly identified habitats used by gray foxes for diurnal refugia. We used GPS collars to obtain location data for 34 gray foxes (20 males and 14 females) from Febr...
