Faecal glucocorticoid and androgen metabolite measurements from Cape mountain zebra, and ecological and demographic measurements of each population

Faecal samples were collected in the field in South Africa and hormone metabolites were extracted in the UK using enzyme immunoassays. Demographic and individual ID information was collected through surveys of populations conducted between 2010-2015. Other columns include ecological, demographic or performance related factors for each population or sampling season (grass abundance, sex ratio, rainfall seasonality, season, population growth rate, foal:mare ratio) or details of the individual from which the sample was collected (sex, status as a herd or bachelor stallion [males], whether the individual had a foal [females], group size). Grass abundance is shown as a standardised vegetation index calculated using vegetation maps on ArcGIS.本数据集的粪便样本采自南非野外，激素代谢物则在英国通过酶联免疫吸附测定（enzyme immunoassays）完成提取。种群人口统计信息与个体ID数据通过2010至2015年间开展的种群调查采集得到。其余数据列涵盖两类信息：一类为各种群或采样季的生态、人口统计及性能相关因子，包括草地丰度、性比、降雨季节性、采样季、种群增长率、幼驹与母马比例；另一类为样本供体个体的详细信息，包括性别、种群种马或单身公马（雄性个体）的身份属性、该个体是否育有幼驹（针对雌性个体）以及群体规模。草地丰度以标准化植被指数形式呈现，该指数通过ArcGIS平台的植被地图计算生成。
