河獭（Lontra canadensis）选择特定的栖息地特征时，建立厕所，但没有研究描述厕所功能在干旱和半干旱环境。我们开发了一个模型，描述这些栖息地的特点，影响水獭厕所选址河流在干旱和半干旱流域西部科罗拉多，美国。河獭选择的厕所网站与海狸（Castor canadensis）活动的存在，大型突出的岩石，邻近较深的水，与阴影的网站，岩石或悬崖上层。我们的模型为识别北美西南部干旱环境中的河水獭厕所地点提供了一个强大的预测工具。
River otters (Lontra canadensis) select specific habitat features when establishing latrines, but no studies have described latrine features in arid and semiarid environments. We developed a model describing those habitat features that influence otter latrine site selection on rivers in arid and semiarid watersheds of western Colorado, USA. River otters selected latrine sites with the presence of beaver (Castor canadensis) activity, large prominent rocks, adjacent to deeper water, with shading over the site, and rock or cliff overstory. Our model provides a robust predictive tool for identifying river otter latrine sites in arid environments of southwestern North America.
