Habitat selection in whiting
Given a choice of habitats in a laboratory experiment, whiting Merlangius merlangus preferentially spent most time over sand, then gravel and least time over a habitat with emergent structures. The introduction of a predator stimulus increased the preference for the sand habitat for large whiting, whereas small whiting had an increased preference for the habitat with emergent structures. # 2004...
متن کاملSeasonal Moose Habitat Selection
The moose is Minnesota’s largest wild animal. In December 2012 moose were proposed as a species of special concern under Minnesota law due to their population decline (Baker, 2012). Time series analysis of the northeast Minnesota moose population estimates conducted by Lenarz (2012) found a significant decline between 2005 and 2012. Moose habitat lacks highly specific requirements, depending mo...
متن کاملCan settlement in natal-like habitat explain maladaptive habitat selection?
The study of habitat selection has long been influenced by the ideal free model, which maintains that young adults settle in habitat according to its inherent quality and the density of conspecifics within it. The model has gained support in recent years from the finding that conspecifics produce cues inadvertently that help prebreeders locate good habitat. Yet abundant evidence shows that anim...
متن کاملHabitat Relations Spatial Heterogeneity in Habitat Selection: Nest Site Selection by Greater Prairie-Chickens
Ecological relationships of animals and their environments are known to vary spatially and temporally across scales. However, common approaches for evaluating resource selection by animals assume that the processes of habitat selection are stationary across space. The assumption that habitat selection is spatially homogeneous may lead to biased inference and ineffective management. We present t...
متن کاملHabitat selection and nicHe conservatism
Niche conservatism is the phenomenon in which species or other phylogenetic lineages seem to exhibit much the same ecological niche over their geographical ranges or over evolutionary time scales. Previous studies have suggested that optimal habitat selection can constrain niche evolution (and thus may help explain niche conservatism), in effect by preventing populations from experiencing unfav...
