Résumé :	Eastern wolves (Canis lycaon) are a species of special concern federally in Canada that have hybridized extensively with coyotes (Canis la trans) and gray wolves (Canis lupus) in and adjacent to Algonquin Provincial Park (APP), Ontario. A comprehensive understanding of eastern wolf demography and wolf-coyote hybridization dynamics is needed for informed management, yet no studies have investigated the influence of genetic ancestry and environmental heterogeneity on survival of wolf, coyote, and hybrid pups. We used telemetry, genetic, and environmental data to model and estimate genotype-specific survival and cause-specific mortality of Canis pups (n = 159) in eastern and western APP (2002-2011) and the adjacent Wildlife Management Unit 49 (WMU49; 2008-2011). Pup survival was higher in eastern APP ((s) over cap= 0.75) and WMU49 (
