Preliminary model selection results.

Preliminary models described the response of antler size to year-of-birth or year-of-harvest weather factors we investigated as potential contributors to the yearly extent of antler growth in mule deer (Odocoileus hemionus) and elk (Cervus canadensis). Data were collected from 27 sites across western North America during 1981–2010. Model descriptions are located in Tables 1 and 2.aModel number.bNumber of model parameters (random, fixed).cAkaike’s Information Criteria.dAIC relative to the best fitting model.eAkaike weight.fModels were judged to include uninformative parameters based on little to no improvement in deviance and fact that model differed from the top by a single variable.
