Age at primiparity is a flexible life history trait that purportedly responds to changing population dynamics and variable resource abundance. We examined placental scars in yearling Canada lynx (Lynx canadensis Kerr, 1792) from the island of Newfoundland and used pregnancy rates and litter sizes to indicate primiparity. We modelled these lynx productivity data with snowshoe hare (Lepus americanus Erxleben, 1777) population attributes using seven multiple a priori competing hypotheses. Hare abundance showed peak, decline and increase phases and densities based on capture-mark-recapture estimates ranged from 0.11 to 1.19 hares ha The accepted manuscript in pdf format is listed with the files at the bottom of this page.
