The role of phenotypic plasticity in responses of hunted thinhorn sheep ram horn growth to changing climate conditions.

Journal of evolutionary biology - 1 Apr 2010

Loehr J, Carey J, O'Hara R B, Hik D S

Abstract excerpt

When phenotypic change occurs over time in wildlife populations, it can be difficult to determine to what degree it is because of genetic effects or phenotypic plasticity. Here, we assess phenotypic changes over time in horn length and volume of thinhorn sheep (Ovis dalli) rams from Yukon Territory, Canada. We considered 42 years of horn growth from over 50,000 growth measurements in over 8000 individuals. We...
