Two reclaimed coal mines in west-central Alberta host a complex assemblage of large-bodied predator and prey populations, including cougars (Puma concolor), bighorn sheep (Ovis canadensis), elk (Cervus elaphus), and mule deer (Odocoileus hemionus). The presence of ungulate and predator...

Ontogenetic patterns in heritable variation for body size: using random regression models in a wild ungulate population
Download2005
Wilson, A.J., Coltman, D.W., Kruuk, L.E.B.
Body size is an important determinant of fitness in many organisms. While size will typically change over the lifetime of an individual, heritable components of phenotypic variance may also show ontogenetic variation. We estimated genetic (additive and maternal) and environmental covariance...

Although typically referred to as a generalist species, individual prey specialization has been documented in cougars (Puma concolor). This behaviour has the potential to limit and regulate ungulate dynamics, particularly in cases where ungulates exist in small or isolated populations. Cougars...
