Abstract: <p>Calcium (Ca) limitation and sodium chloride (NaCl) toxicity tolerance are potential controllers of Daphnia populations. D. pulicaria neonates collected from 14 Kawartha Highland lakes were exposed to 6 Ca concentrations (0.5-5.0 mg Ca L-1) over 6 days. We did not find differences in maximum mass-specific growth rate or half-maximum thresholds between source lakes. Growth rates were… more
Abstract: <p>Trait variation in wild populations is shaped by the interaction of genetics and the environment. Given these interactions, this thesis explored trait variation in white-tailed deer from two angles: one focused on broad-scale environmental factors, the other on fine-scale genetic mechanisms. The first chapter investigated how climate and habitat variation influence antler size,… more
