Comparing multiple species distribution proxies and different quantifications of the human footprint map, implications for conservation

摘要: Abstract Anthropogenic threats drive species to extinction and are the focus of risk analyses conservation planning. Threats often quantified through higher level proxies, such as human footprint (HF). We tested effects that multiple methods representing species’ distribution different quantifications a HF map have on threat measurement, how these influence decisions. magnitude for 901 Southeast Asian mammals according several methods. ranked measured value, produced priority lists top-impacted species. The representations caused significant disagreement in calculations. values were average lower when calculated suitable habitat or occurrence points comparison whole geographic range. Biases non-linear dependent distal factors, proportion within range specialism. Using also yielded disagreement, with 2–56% difference observed membership among lists. Threatened best predicted, significantly placed top-ranking, measuring their exposed high levels HF. thus show extent, not only its determines risk. A well-framed global strategy must address quantification impact biodiversity. selection has implications is evaluated. Improving techniques quantify biodiversity will enhance effectiveness
