摘要: High-elevation forests that contain mature, closed canopy stands are considered important habitat for American martens (Martes americana (Turton, 1806)) in the northeastern United States. To investigate this hypothesis, we monitored 15 radio-collared over a 2-year period and measured spatial use, as well second- third-order resource selection, from 33 seasonal home ranges 889 telemetry locations. The population was composed primarily of adults had small home-range size with average fidelity. During leaf-off seasons, selected against regenerating forest at both scales mixedwood softwood areas rugged terrain within ranges. Second-order selection less pronounced during leaf-on yet exhibited greater hardwood Home-range correlated positively amount body-condition index scores were lower during...
