Geographic range-scale assessment of species conservation status: A framework linking species and landscape features

摘要: Abstract The concept of habitat and spatial extent are key features in landscape ecology. A non-precise definition the wrong choice scale can affect model outcomes our understanding about population conservation status. We proposed a framework applied to five species representing different ecological profiles (1) occurrences (2) evaluate structure at nine extents from local landscapes entire range. Then, we (3) evaluated sensitivity each metric (4) assessed if changed according species. Our was succesfull predicting occurrence for all When deductive suitability models, total area remaining varied 83% 12% original extension occurrence. On average, proportion amount, fragmentation, carrying capacity decreased functional increased as increased. Habitat amount fragmentation locally would show same pattern across species’ range, but connectivity – which consider biological were affected by scale. Also, inclusion preferences on modeling diminished commission errors arising landscape-scale underestimation occurrences. Local samples not able represent range feature way that individuals reach depends features. Species status should be preferably include an additional factor determining occupancy inside geographic ranges.
