Diseases and reproductive success in a wild mammal: example in the alpine chamois

摘要: Density-dependent and climatic factors affect reproduction dynamics of wild ungulates. Parasites can also decrease reproductive success through either a direct abortive effect or negative impact on host growth body condition. However, few studies have investigated the parasitism fecundity ungulates in natural conditions. We studied three bacterial infections caused by Salmonella enterica serovar Abortusovis, Chlamydophila abortus Coxiella burnetii. These bacteria are leading causes failure sheep, goat cattle, which raises question their influence population A long-term study demography epidemiology an alpine chamois (Rupicapra rupicapra, L.) (Les Bauges Reserve, France) generalized linear modeling approach were used to analyze according density, weather conditions prevalence antibodies against females. This enabled us identify confounding population. After accounting for explained 36% annual variation success, additional 31%. was, our knowledge, first compare due mountain
