Mammalian carnivores have suffered the biggest range contraction among all biodiversity and are particularly vulnerable to habitat loss and fragmentation. Therefore, we identified priority areas for the conservation of mammalian carnivores, while accounting for species-specific requirements for connectivity and expected agricultural and urban expansion. While prioritizing for carnivores only, w...

in this survey 45 carnivores including 14 jackals, 23 stray dogs, 2 foxes, 2 domestic cats, 1 wild cat, 2 swine and 1 wolf were collected. on post-mortem examination, 84% carcases were infected and 13 zoonotic helminth species were recovered. dirofilaria immitis was the most commonly parasite and toxocara canis showed the highest intensity of infection. one species from swine and two helminth s...

Carnivores play important roles in structuring communities, and their populations are useful indicators of ecosystem condition (Wennergren and others 1995, Buskirk 1999, Crooks and Soulé 1999, Terborgh and others 2001). As many as 4 of 20 native mammalian carnivore species have been extirpated from the southern Cascade Mountains and Sierra Nevada, with unmeasured effects on ecological communiti...

Captive carnivores are susceptible to a wide array of infectious and parasitic diseases, which reflects the diversity of the seven families of Carnivora. Unfortunately, relatively few in-depth studies have been conducted on diseases of non-domestic carnivores, and much remains to be learned, especially regarding diseases of small carnivores (e.g. mustelids, viverrids and procyonids). The more i...

Manuscript 1001; Received 14 Feb 2003; Revised finally accepted 29 April 2004; © Zoo Outreach Organisation 1540 ABSTRACT Helminthiasis in wild carnivores can cause high morbidity and mortality specially in young ones. This paper discusses in brief on the occurrence of helminthic infestation in wild carnivores as reported from India. They suffer from trematodes, cestodes, nematodes and acanthoce...

Terrestrial ecosystems are generally green with vegetation and only a small part (<10%) of the total plant matter is consumed by herbivores annually, which means herbivore density is consistently low and stable. Nonetheless, the mechanism underlying this pattern has been unclear due to the lack of suitable food-web models for predicting the absolute density of the herbivore biomass in physical ...

Cats and dogs have relatively good sound-localization acuity, and the question arises as to whether this trait is a characteristic of all carnivores or whether it is due to the fact that they have large heads and correspondingly large binaural localization cues available to them. The localization acuity of the least weasel, the smallest extant carnivore, was found to be less accurate than large...

BACKGROUND Placental research in carnivores has concentrated on domestic species, which have zonary, labyrinthine placentas with an endotheliochorial barrier. Although the coati, Nasua nasua, is a widely distributed species in South America, data on the development of the placenta and the fetal membranes in this species are very sparse. FINDINGS Four placentas from mid-gestation to near term ...
