These data provide additional information relevant to the frequency of fisher detections by camera traps, and single-season occupancy and local persistence of fishers in small patches of forest habitats detailed elsewhere, "Landscape Fuel Reduction, Forest Fire, and Biophysical Linkages to Local Habitat Use and Local Persistence of Fishers (Pekania pennanti) in Sierra Nevada Mixed-conifer Forests" [10]. The data provides insight on camera trap detections of 3 fisher predators (bobcat [Lynx rufus]). Coyote [Canis latrans], mountain lion [Puma concolor], 5 mesocarnivores in the same foraging guild as fishers (gray fox [Urocyon cinereoargenteus]) ringtail [Bassariscus astutus], marten [Martes americana], striped skunk [Mephitis mephitis] spotted skunk [Spilogale gracilis], and 5 Sciuridae rodents that fishers consume as prey (Douglas squirrel [Tamiasciurus douglasii]), gray squirrel [Sciurus griseus], northern flying squirrel [Glaucomys sabrinus], long-eared chipmunk [Neotamias quadrimaculatus], California ground squirrel [Spermophilus beecheyi]. We used these data to identify basic patterns of co-occurrence with fishers, and to evaluate the relative importance of presence of competing mesocarnivores, rodent prey, and predators for fisher occupancy of small, 1 km(2) grid cells of forest habitat.
这些数据提供了与相机陷阱检测渔貂的频率相关的额外信息，以及在其他地方详细描述的小片森林栖息地中渔貂的单季占有率和局部持久性，即“内华达山脉混交林的景观燃料减少、森林火灾以及与当地栖息地利用和渔貂（Pekania pennanti）局部持久性的生物物理联系”[10]。该数据提供了关于相机陷阱检测到的3种渔貂捕食者（短尾猫[Lynx rufus]、郊狼[Canis latrans]、美洲狮[Puma concolor]）、5种与渔貂处于同一觅食 guild 的中型食肉动物（灰狐[Urocyon cinereoargenteus]、环尾猫[Bassariscus astutus]、貂[Martes americana]、条纹臭鼬[Mephitis mephitis]、斑点臭鼬[Spilogale gracilis]）以及5种渔貂作为猎物捕食的松鼠科啮齿动物（道格拉斯松鼠[Tamiasciurus douglasii]、灰松鼠[Sciurus griseus]、北方飞鼠[Glaucomys sabrinus]、长耳花栗鼠[Neotamias quadrimaculatus]、加利福尼亚地松鼠[Spermophilus beecheyi]）的见解。我们利用这些数据来识别与渔貂共生的基本模式，并评估竞争性中型食肉动物、啮齿动物猎物和捕食者的存在对森林栖息地1平方公里网格小单元中渔貂占有率的相对重要性。
