The spatial structure of habitat selection by caribou (Rangifer tarandus caribou) in Newfoundland: new multi-scaled approaches with applications to limiting factors
Habitat selection is a multi-scaled phenomenon. Selection depends on the scales perceived by organisms, while our ability to detect selection depends on analytical scale. Traditional studies of habitat selection have been limited by the use of discrete, arbitrary scales, because a quantitative basis...
