Models of eight most consumed diet categories.

Summary of model results for the eight most commonly consumed diet categories. Dashes indicate parameters that were not included in the final model. Coefficient estimates, in the first column under each explanatory variable, are reported on the log-odds scale. Baseline categories were Sheep Creek for the stream variable and mountain whitefish for the species variable. Adjusted deviance explained for each model was Athericidae = 0.40, Baetidae = 0.40, Brachycentridae = 0.32, Chironomidae = 0.52, Ephemerellidae = 0.08, Heptageniidae = 0.19, Hydropsychidae = 0.57, and Oligochaeta = 0.56.八种最常见摄食类别的模型结果汇总。破折号表示未纳入最终模型的参数。各解释变量下方第一列所报告的系数估计值，均以对数胜算比（log-odds）尺度呈现。流变量的基准类别为Sheep Creek，物种变量的基准类别为山地白鲑（mountain whitefish）。各模型的校正偏差解释率如下：距虻科（Athericidae）=0.40、四节蜉科（Baetidae）=0.40、短石蛾科（Brachycentridae）=0.32、摇蚊科（Chironomidae）=0.52、细蜉科（Ephemerellidae）=0.08、扁蜉科（Heptageniidae）=0.19、纹石蛾科（Hydropsychidae）=0.57以及寡毛纲（Oligochaeta）=0.56。
