Three-year mean ± SE, sample size (n), minimum (min.) and maximum (max.) values and test statistics representing cast-antler metrics (points, gross score, main beam length [MBL], tine length [G1–G4], circumference [H1–H4], diameter [D1–D4], pedicle seal diameter [Seal Dia.], and depth and antler mass) of yearling white-tailed deer Odocoileus virginianus from the Platte River Valley, Nebraska, USA, 2010–2012. One-way analysis of variance or Kruskal–Wallis (MBL, G1, H2, seal depth, and mass) test results describe the lack of variability among years for each antler metric. Reported metrics are in mm, except for points (number of points), gross score (as determined following Nesbitt and Wright 2009), and mass (g).
