Locations of 70 Sacramento Valley red fox (Vulpes vulpes patwin) den sites and road kills (black circles) in reference to geographic landmarks and two Maxent model predicting distribution in the Sacramento Valley, California: (A) the full model, based on vegetation type, distance to grasslands, distance to development, and (B) a 2-variable model, based on vegetation type and distance to grasslands (i.e., excluding distance to development). All data shown were collected during 2007–2009.

本数据集收录了加利福尼亚州萨克拉门托河谷内70处萨克拉门托河谷赤狐（Vulpes vulpes patwin）的巢穴位点与道路致死个体的空间坐标，所有点位以黑色圆圈标记，相关展示结合了地理地标与两个用于预测该区域赤狐分布的Maxent模型（Maxent）：(A) 全变量模型，以植被类型、距草地距离、距人类开发区域距离为构建变量；(B) 双变量模型，仅以植被类型与距草地距离为构建变量（即剔除了距人类开发区域距离这一变量）。本图展示的全部数据采集于2007年至2009年期间。
