To test the hypothesis that the domestic dogs are derived from several different ancestral gray wolf populations, we compared the sequence of the displacement (D)-loop region of the mitochondrial DNA (mtDNA) from 24 breeds of domestic dog (34 individual dogs) and 3 subspecies of gray wolf (Canis lupus lupus, C.l. pallipes and C.l. chanco; 19 individuals). The intraspecific sequence variations w...

A widely accepted definition of genetic rescue from the classic review by Tallmon et al. (2004) is: “when population fitness, inferred from some demographic vital rate or phenotypic trait, increases by more than can be attributed to the demographic contribution of immigrants.” However, this definition limits assessment of the success of genetic rescue, decreases the probability of detecting ben...

BACKGROUND Predation and hunter harvest constitute the main mortality factors affecting the size and dynamics of many exploited populations. The re-colonization by wolves (Canis lupus) of the Scandinavian Peninsula may therefore substantially reduce hunter harvest of moose (Alces alces), the main prey of wolves. METHODOLOGY/PRINCIPAL FINDINGS We examined possible effects of wolf presence on h...

A 3-year-old wild gray wolf was referred to the Department of Veterinary Clinical Sciences of ShirazUniversity with a history of car accident. The radiographic examination showed supracondylar distal femoralfracture in right leg. The wolf was pre-medicated by acepromazine followed by induction of anesthesia usinga combination of diazepam and ketamine. Anesthesia was maintained by halothane. The...
