During the Pleistocene, South America had several genera and species of large hypercarnivorous canids, which became completely extinct at end this epoch. This paper presents a comprehensive systematic review group (four genera, seven species) based on new cladistic analyses that include genomic information study intraspecific variation in canids. The results generated are discussed context know...

In a study of more than 3000 participants from nine countries, we explored peoples’ preferences for the conservation two groups species that frequently interact with humans: large carnivores (n = 29 in order Carnivora average adult body mass > 15 kg), and wild canids felids 73 species). We presented pairs photographs recorded which they would prioritise conservation. also attempted to identify ...

In an effort to identify rapidly evolving nuclear sequences useful for phylogenetic analyses of closely related species, we isolated two genes transcribed by RNA polymerase III (pol III), the selenocysteine tRNA gene (TRSP) and an RNase P RNA (RPPH1) gene from the domestic dog (Canis familiaris). We focus on genes transcribed by pol III because their coding regions are small (generally 100-300 ...

American trypanosomiasis and leishmaniasis are caused by related hemoflagellate parasites, Trypanosoma cruzi and Leishmania spp., which share several common host species. Both zoonotic protozoans are endemic in the United States. Canines, including domestic and wild canids, are reservoir hosts for human infections with T. cruzi and Leishmania spp. The present study examined the seroprevalence o...

We summarize the behavior of several species of canids (coyotes, dingoes, and gray wolves) in relation to their habituation to humans and to human food sources. Striking parallels exist between coyotes and other wild canids in terms of the inclination of individual animals to act aggressively toward humans and even attack, once they have come to associate humans with food. We describe the stage...

Introduction The phylogenetic and ecological importance of paranasal sinuses in carnivorans was highlighted by several previous authors, mostly extant species. Nevertheless, no specific study on this feature canids, one fossil representatives the family, has been published up to now. Here, we analyze for first time sinus canids through computed tomographic techniques characterize them morpholog...

Thirty-six species of canid exist globally, two are classified as critically endangered, three and five near threatened. Human expansion the coinciding habitat fragmentation necessitate conservation interventions to mitigate concurrent population deterioration. The current management wild canids includes animal translocation artificial pack formation. These actions often cause chronic stress, l...

To determine whether deer can transmit Neospora caninum, brains of naturally infected white-tailed deer (Odocoileus virginianus) were fed to 4 dogs; 2 of these dogs shed oocysts. Oocysts from 1 of the dogs were tested by polymerase chain reaction and found to be positive for N. caninum and negative for Hammondia heydorni. The internal transcribed spacer 1 sequence of the new strain (designated ...

BACKGROUND The present study was aimed to elucidate the status of intestinal helminth infections in canids of Moghan Plain, northwestern Iran. METHODS Eighty-five intestine samples from dead or shot wild canids, 59 fecal samples from sheepdogs and 5 from red foxes were collected from 2006 to 2008 and examined in Parasitology department of Pasteur Institute of Iran. RESULTS Generally, adult ...

The risk of disease transmission from waterborne protozoa is often dependent on the origin (e.g., domestic animals versus wildlife), overall parasite load in contaminated waterways, and parasite genotype, with infections being linked to runoff or direct deposition of domestic animal and wildlife feces. Fecal samples collected from domestic animals and wildlife along the central California coast...
