Data from: Hunting promotes sexual conflict in brown bears

Data_Archiving_JAE-2015-00663Cub survival before (den emergence to mid-May), during (mid-May to mid-July), and after the mating season (mid-July to November) in brown bears in Sweden. Each line represents a litter. 'FemaleID' is the ID of the mother of the litter. Age indicates the age (years) of the mother. Status is the parity of the mother (primiparous or multiparous). Distance to the closest male killed is to the closest registered adult male killed within the 1.5 previous years. Timelag is whether the closest male was killed 0.5 or 1.5 years before the litter was born. The number of male shot are the number of registered adult male killed within the previous 1.5 years in a radius of 25km of a litter or between a radius of 25 to 80km of a litter. 'Population_density' is an index that approximate the number of bears within 1000 km² around the home range center of a litter. 'Food_index' is an index of the general food condition of the study population for each year.

数据集存档编号：Data_Archiving_JAE-2015-00663，本数据集包含瑞典棕熊的幼崽存活率数据，统计时段分为三个阶段：交配季前（洞穴出眠至5月中旬）、交配季中（5月中旬至7月中旬）以及交配季后（7月中旬至11月）。数据文件每行对应一窝幼崽，各字段说明如下：
1. 母本个体ID（FemaleID）：该窝幼崽母本的唯一标识编号；
2. 母本年龄（Age）：母本的实际年龄，单位为年；
3. 母本生育状况（Status）：记录母本为初产个体或经产个体；
4. 至最近死亡雄熊的距离（Distance to the closest male killed）：指该窝幼崽所在区域内，过去1.5年内登记在册的最近死亡成年雄熊与该窝幼崽的空间距离；
5. 时间差（Timelag）：用于标记最近的登记死亡成年雄熊是否在该窝幼崽出生前0.5年或1.5年时死亡；
6. 射杀成年雄熊数量：统计该窝幼崽所在区域过去1.5年内的登记死亡成年雄熊总数，统计范围分为两类：一是幼崽周边25公里半径范围内，二是幼崽周边25至80公里半径范围内；
7. 种群密度指数（Population_density）：该指数用于估算幼崽家域中心周边1000平方公里范围内的棕熊种群数量；
8. 食物丰度指数（Food_index）：用于反映该研究种群每年的整体食物条件状况。
