Antler and Body Size in Black-Tailed Deer: An Analysis of Cohort Effects

Figure 5

Trends in size of male black-tailed deer in Hopland, California, USA. (a) The increase in body size (dressed weight corrected for age) between years. (b) The increase in antler size (principle component 1 corrected for age) through time. Sections are partitioned by pretreatment (only males harvested, 1980–1984), treatment (both males and females harvested, 1985–1990), and posttreatment (only males harvested, 1991–1997). Arrows point to the four largest individual males and identify the age of each male at time of harvest.
