Grass biomass and nitrogen data from carcass sites

Grass data collected at anthrax negative, plains zebra carcass sites one, two and three years after death. Samples were collected 1.5m (zone 1), 4.5m (zone 2) and 7.5m (zone 3) from carcass centers. Measurements include grass biomass (g/m^2) averaged across the two replicate quadrats sampled and grass nitrogen, measured as Kjeldahl N. NA values for nitrogen samples were of insufficient mass for analysis.

本数据集采集自炭疽检测呈阴性的平原斑马尸体位点，涵盖斑马死亡后1年、2年及3年的三个采样位点。采样点距尸体中心的距离分别为1.5米（区域1）、4.5米（区域2）与7.5米（区域3）。测定指标包括：以两次重复采样样方（quadrats）的平均值计算得到的草本生物量（单位：克/平方米），以及采用凯氏定氮法（Kjeldahl N）测定的草本全氮含量。氮含量样本的缺失值（NA）系因样品质量不足，无法开展分析。
