Large‐scale climatic fluctuation and population dynamics of moose and white‐tailed deer
1. Mech et al . (1987) documented cumulative, negative effects of previous winters’ snow on rates of population increase in moose ( Alces alces ) and white‐tailed deer ( Odocoileus virginianus ), but noted no effect of predation by wolves ( Canis lupus ). Those results were contested by Messier (199...
