Habitat and climate variables in the best supported ecological hypotheses to explain habitat selection during 3 seasons by female Dall’s sheep (Ovis dalli dalli) in Lake Clark National Park and Preserve, Alaska, USA.

Variable group, habitat and climate variables, positive or negative effects on selection, season (winter, spring, or summer), ecological hypotheses (Security + Thermal + Movement + Nutrition or Security + Nutrition), and number of parameters (K) are shown. North, South, or both refers to the distinct regions where radio-collared females occurred (see Fig 2). See S1 Table for a description of each habitat and climate variable and S2 Text for variable reduction and model selection steps.本研究列出了变量组、生境与气候变量、对选择的正负效应、季节（冬季、春季或夏季）、生态假说（安全（Security）+热调节（Thermal）+移动（Movement）+营养（Nutrition）或安全（Security）+营养（Nutrition））以及参数数量（K）。北部、南部或两者兼指佩戴无线电项圈的雌性个体的分布区域（见图2）。各生境与气候变量的详细说明详见S1表，变量简化与模型选择步骤详见S2文本。
