Targeting habitat management in fragmented landscapes: a case study with forest vertebrates

摘要: Although improving the quality of habitat patches in fragmented landscapes is a main conservation target few studies have examined patch management relation to surrounding landscape. Tackling such an issue needs cross-scale approach that takes hierarchical nature into account. Here I show results study focusing on distribution patterns ten forest vertebrate species (birds and mammals). The overarching goal this was understand strength scale determinants distribution, following appropriate control for relevant landscape properties (e.g. loss vs. subdivision). how, after controlling uncertainty detection role properties, variables still played important determining occupancy vertebrates. For some variation values structure increased occurrence probability with only moderate levels loss, highlighting fact should be targeted towards precise conditions. In other cases effect strong therefore their always brought substantial increase/decrease presence probability. Overall these strongly suggest never carried out irrespective landscape, rather, it carefully specific contexts above certain amount habitat) where more likely effective.
