We found a strong association between the lower elevation limits of bull trout distributions and longitude and latitude; this association was consistent with the patterns in mean annual air temperature.

Although carefully collected, accuracy cannot be guaranteed. Retrieved 10 May This has led to models that can be used to predict the movement patterns of individuals, the dynamics of species, and the distributional patterns in multispecies communities in real fragmented landscapes. Integrating results from such studies into land management plans and decision making, however, is not a trivial task because the effects of fragmentation:

Abstract - Cited by 9 1 self - Add to MetaCart Many populations exhibit pronounced spatial structure: This concept seems appropriate for those species that have patchy distributions because the critical resources on which they depend are distributed in this fashion. The species-area relationship, the lack of importance of habitat diversity, the increasing frequency of unoccupied small islands Consequences of impediments to animal movements at different scales: The amount and pattern of cutting in a landscape that extends across a region will have less effect than the same amount and configuration in a landscape type that is confined to a small locale.
