Rabies in Endangered Ethiopian Wolves
With rabies emerging as a particular threat to wild canids, we report on a rabies outbreak in a subpopulation of endangered Ethiopian wolves in the Bale Mountains, Ethiopia, in 2003 and 2004. Parenteral vaccination of wolves was used to manage the outbreak.
متن کاملEvolution of sex-biased dispersal: the role of sex-specific dispersal costs, demographic stochasticity, and inbreeding
Inbreeding avoidance and asymmetric competition over resources have both been identified as factors favouring the evolution of sex-biased dispersal. It has also been recognized that sex-specific costs of dispersal would select for sex-biased dispersal, but there is little quantitative information on this aspect. In this paper we explore (i) the quantitative relationship between cost-asymmetry a...
متن کاملInbreeding and inbreeding depression in endangered red wolves (Canis rufus).
In natural populations, the expression and severity of inbreeding depression can vary widely across taxa. Describing processes that influence the extent of inbreeding and inbreeding depression aid in our understanding of the evolutionary history of mating systems such as cooperative breeding and nonrandom mate selection. Such findings also help shape wildlife conservation theory because inbreed...
متن کاملCanine Distemper in Endangered Ethiopian Wolves
The Ethiopian wolf (Canis simensis) is the world's rarest canid; ≈500 wolves remain. The largest population is found within the Bale Mountains National Park (BMNP) in southeastern Ethiopia, where conservation efforts have demonstrated the negative effect of rabies virus on wolf populations. We describe previously unreported infections with canine distemper virus (CDV) among these wolves during ...
متن کاملRelationship between female mating strategy, litter success and offspring dispersal.
The relationship between mating systems and dispersal has generally been studied at the population and species levels. It has hardly ever been investigated at the individual level, by studying the variations of mating and dispersal strategies between individuals. We investigated this relationship in a natural population of the common lizard (Lacerta vivipara). Assuming that dispersal has a gene...
