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

Table 3

Component models for antler size (PC1). Term codes: A: average temperature during the wet season of the first year of growth, B: total precipitation during the dry season before harvest, C: total precipitation during the wet season before harvest, D: average temperature during the dry season before harvest, E: weight corrected for age (residuals), F: total precipitation while the male was in utero during the gestation by the mother, G: average temperature while the male was in utero during the gestation by the mother, H: treatment period (index for population density) while the male was in utero during the gestation by the mother, I: treatment period (index for population density) during the first year of growth, J: total precipitation during the dry season of the first year of growth, K: total precipitation during the wet season of the first year of growth, L: average temperature during the dry season of the first year of growth, M: interaction term between precipitation and treatment during the wet season of the first year of growth, N: interaction term between precipitation and treatment during the wet season of the first year of growth. Data for these models was from harvested black-tailed deer from Hopland, California, USA, from 1980 through 1997.
