Local suitability estimated with species distribution models (SDMs) could indicate the maximum abundance attainable by species. Often the abundance–suitability relationship is wedge‐shaped because species do not reach their maximum potential in every suitable location. We explore how SDM performance, the amount of information lost when converting continuous abundance into presence–absence data and species prevalence influence the abundance–suitability relationship.

解构物种分布模型中的丰度与适宜性关系

用物种分布模型（SDM）估算的当地适宜性可能表明物种可达到的最大丰度。丰度与适宜性之间的关系通常是楔形的，因为物种没有在每个合适的位置都达到最大潜力。我们探索了SDM性能，将连续的丰度转换为存在-缺乏数据和物种流行度时丢失的信息量如何影响丰度-适应性关系。
