13. Toxocara canis (Werner, 1782) eggs in the Pleistocene site of Menez-Dregan, France (300,000-500,000 years before present)
On the archaeological site of Menez-Dregan in Brittany, France, dated 300,000-500,000 years-old, paleoparasitological analysis of cave deposits led to the detection of well-preserved helminth eggs, which morphology and morphometry pointed to the diagnosis of Toxocara canis eggs, a parasite of carnivore mammals. Paleolithic remains suggested a parasitism of t

14. Epidemiologia e genética populacional de lobos guarás, Chrysocyon brachyurus, (ILLIGER 1815) (CARNIVORA, CANIDAE) no nordeste do estado de São Paulo
This study was accomplished in the northeastern area of the state of São Paulo, obtaining biological material of maned wolves for the epidemiology (parasitic diseases) and populacional genetic study. The occurrences of deaths were also verified and the relationships between the farmers and wolves were appraised. In the studies of parasitic diseases, infesta

15. Calibration of estimated biting forces in domestic canids: comparison of post-mortem and in vivo measurements
Estimates of biting forces are widely used in paleontological and comparative studies of feeding mechanics and performance, and are usually derived from lever models based on measurements made on the skull that are relevant to the mechanics of the masticatory system. Owing to assumptions and unmeasurable errors in their estimation, such values are used compa

16. The evolution of orbit orientation and encephalization in the Carnivora (Mammalia)
Evolutionary change in encephalization within and across mammalian clades is well-studied, yet relatively few comparative analyses attempt to quantify the impact of evolutionary change in relative brain size on cranial morphology. Because of the proximity of the braincase to the orbits, and the inter-relationships among ecology, sensory systems and neuroanat

17. Regular exposure to rabies virus and lack of symptomatic disease in Serengeti spotted hyenas
We report a previously unrecognized complexity to the ecology of rabies in wildlife. Rabies-specific virus-neutralizing antibodies in spotted hyenas, the most numerous large carnivore in the Serengeti ecosystem (Tanzania, East Africa), revealed a high frequency of exposure of 37.0% to rabies virus, and reverse transcriptase (RT) PCR demonstrated rabies

18. The phylogeny of the red panda (Ailurus fulgens): evidence from the hindlimb
The red panda (Ailurus fulgens) is an endangered carnivore living in the temperate forests of the Himalayas and southern China. The phylogeny of the red panda has been the subject of much debate. Morphological and molecular studies have supported a wide range of possible relationships, including close ties to procyonids, ursids, mustelids, and mephitids. Thi
