Functional and geographic components of risk for climate sensitive vertebrates in the Pacific Northwest, USA

摘要: Abstract Rarity and life history traits inform multiple dimensions of intrinsic risk to climate environmental change can help systematically identify at-risk species. We quantified relative geographic rarity (area occupancy), niche breadth, for 114 freshwater fishes, amphibians, reptiles in the U.S. Pacific Northwest. Our approach leveraged presence-only, publicly available data traits-based inference evaluate area occupancy, sensitivity (i.e., breadth), a Climate Sensitivity (RCS) index all species across extents, grain sizes, types. The RCS was relatively stable grains, types, with differentiating otherwise similar areas occupancy. also found that sensitivity-associated (e.g., long generation time, low fecundity) were not necessarily same identified as geographical approaches (small range size, small breadth). Many multispecies assessments using coarse-scale entire maps or convex-hull approaches) often focus on single dimension risk; others rely data-intensive models only applicable few well-studied What remains is need an enables multispecies, multidimensional assessment efforts. This particularly true at regional scales, where management needs require are intermediate coarse- fine-scale approaches. demonstrate by considering (range sensitivity, traits), site-specific locality may offer pathway ensuring vulnerable, understudied do go overlooked conservation.
