3.Gender_DominanceRank_Age_Body_Size_of_Individual_Dogs

This files contains data concerning gender, dominance rank, age and body size for some of the dogs studied. In particular, body measurements were collected for members of two dog packs, one studied during the period 2005-2006 (most behaviorual data analyses concerning this group were published by Cafazzo et al. 2010, Behav Ecol 21, 443-455), and another one studied during 2007-2008 (most behavioural data analyses concerning this one are included in Bonanni et al. 2017). As said above, the variable “age class” does not express the actual age of dogs in years, but rather it ranks pack members from the youngest (lowest rank) to the oldest one (highest rank). All body measurements are espressed in cm. Head size was obtained by summing up three distances: nose-occipital bone, temporal-temporal, mandible-forehead. Empty cells refer to missing values. In the original paper by Bonanni et al. (2017), these data were used to: 1) assess the correlation between standardized dominance rank and body measurements (separately for each pack); 2) assess the partial correlation between dominance rank and age, after controlling for body size (it was feasible only for the Corridoio pack); 3) assess the partial correlation between dominance rank and body measurements after controlling for age (it was feasible only for the Corridoio pack; 4) assess the effect of gender on the body measurements (all measured individuals taken together). Note that one female dog was a member of both packs at different times, and her body measurements were used in the statistical tests concerning both packs since she was already fully adult/grown during the study period 2005-2006.本数据集包含部分受试犬的性别、优势等级、年龄及体尺相关数据。具体而言，研究人员为两个犬群的成员采集了体尺测量数据：其中一个犬群的观测周期为2005-2006年，针对该群体的大部分行为学数据分析已由Cafazzo等人于2010年发表于《Behavioral Ecology》（*Behav Ecol*）21卷，443-455页；另一个犬群的观测周期为2007-2008年，针对该群体的大部分行为学数据分析收录于Bonanni等人2017年的研究中。如前所述，"年龄组"变量并非以周岁表示受试犬的实际年龄，而是将犬群成员按年龄从最年轻（等级最低）至最年长（等级最高）进行排序。所有体尺测量指标的单位均为厘米（cm）。头部尺寸通过三项距离之和计算得出：鼻-枕骨距离、颞-颞距离以及下颌-前额距离。空单元格代表缺失值。在Bonanni等人2017年的原始研究中，本数据集被用于以下4项分析：1）分别针对两个犬群，评估标准化优势等级与体尺测量指标间的相关性；2）在控制体尺变量的前提下，评估优势等级与年龄的偏相关关系（该分析仅可应用于Corridoio犬群）；3）在控制年龄变量的前提下，评估优势等级与体尺测量指标间的偏相关关系（该分析仅可应用于Corridoio犬群）；4）评估性别对体尺测量指标的影响（纳入所有被测个体）。需注意，有1只母犬在不同时段分别隶属于两个犬群，因其在2005-2006年的观测周期内已完全发育成熟，因此其体尺数据被纳入针对两个犬群的统计检验中。
