American black bears (Ursus americanus) were extirpated from Oklahoma, USA, in the early twentieth century but have since recolonized eastern portions of the state after immigrating from Arkansas, where they were successfully translocated. Within the last 2 decades, a population of black bears was detected in the Oklahoma Ozark region, prompting studies to determine population size, growth rate, and genetic makeup. To understand how black bears were recolonizing the human‐dominated landscape, we investigated resource selection at 2 scales. Between 2011 and 2016, we collected global positioning system collar spatial data for 10 males and 13 females. We calculated average kernel density home ranges on a seasonal scale for all collared bears. We used generalized linear mixed models to calculate resource selection functions at the study area, defined by locations of all radio‐collared black bears (second order) and the scale of individual black bear home ranges (third order). Resource selection did not differ significantly by sex. Black bears across seasons and scales selected riparian forest and moist oak (Quercus spp.) forest land cover types and mostly selected against indicators of human activity (e.g., pasture‐prairie, anthropogenic land cover types, roads, and areas of high human population density). Black bears also selected areas with rugged terrain at high elevations, although not consistently across seasons and scales. Black bear recolonization appeared to be negatively affected by areas and features characterized as human‐altered. Further expansion of the range of black bears may be limited by anthropogenic disturbance in the region. © 2021 The Wildlife Society.

重新定殖美国黑熊的资源选择

美国黑熊（美洲熊））于20世纪初期从美国俄克拉荷马州灭绝，但此后从阿肯色州移民并成功移居该州，从而重新定居了该州的东部地区。在过去的20年中，俄克拉荷马州奥扎克地区发现了黑熊种群，这促使人们进行研究以确定种群的大小，增长率和基因组成。为了了解黑熊如何重新定居人类主导的景观，我们以2个尺度调查了资源选择。在2011年至2016年之间，我们收集了10位男性和13位女性的全球定位系统衣领空间数据。我们按季节尺度计算了所有圈养熊的平均内核密度归巢范围。我们使用广义线性混合模型来计算研究区域的资源选择函数，由所有电波黑熊的位置（第二阶）和单个黑熊的家园范围（第三阶）定义。性别的资源选择没有显着差异。跨季节的黑熊，并缩放选定的河岸森林和潮湿的橡树（栎树（Quercus spp。）林地覆盖类型，并且大多数是根据人类活动指标（例如，牧场-草原，人为土地覆盖类型，道路和人口密度高的地区）选择的。黑熊还选择了高海拔地区崎areas不平的地区，尽管在整个季节和规模上并不一致。黑熊的殖民化似乎受到人类改变的区域和特征的负面影响。黑熊范围的进一步扩大可能受到该地区人为干扰的限制。©2021野生动物协会。
