| presence of rabies neutralizing antibodies in wild carnivores following an outbreak of bovine rabies. | in an outbreak of bovine rabies in argentina, a study was made of vampire bats (desmodus rotundus) and wild carnivores. rabies antibody rates of high prevalence were found in the bats, foxes (dusicyon gymnocercus) and skunks (conepatus chinga). the outbreak was part of an extensive continuing epizootic of vampire transmitted bovine rabies which may have also involved other vectors in the area of this study. consumption of dead and dying bats by the carnivores is the suggested means of passage of ... | 1975 | 1142554 |

| a comparative study of trypanosoma cruzi infection in sylvatic mammals from a protected and a disturbed area in the argentine chaco. | understanding the complex epidemiology of trypanosoma cruzi transmission cycles requires comparative studies in widely different environments. we assessed the occurrence of t. cruzi infection in sylvatic mammals, their infectiousness to the vector, and parasite genotypes in a protected area of the argentine chaco, and compared them with information obtained similarly in a nearby disturbed area. a total of 278 mammals from >23 species in the protected area were diagnosed for t. cruzi infection us ... | 2016 | 26708994 |
| species-specific responses of carnivores to human-induced landscape changes in central argentina. | the role that mammalian carnivores play in ecosystems can be deeply altered by human-driven habitat disturbance. while most carnivore species are negatively affected, the impact of habitat changes is expected to depend on their ecological flexibility. we aimed to identify key factors affecting the habitat use by four sympatric carnivore species in landscapes of central argentina. camera trapping surveys were carried out at 49 sites from 2011 to 2013. each site was characterized by 12 habitat att ... | 2016 | 26950300 |
| medicinal use of wild fauna by mestizo communities living near san guillermo biosphere reserve (san juan, argentina). | wild and domestic animals and their by-products are important ingredients in the preparation of curative, protective and preventive medicines. despite the medicinal use of animals worldwide, this topic has received less attention than the use of medicinal plants. this study assessed the medicinal use of animals by mestizo communities living near san guillermo mab reserve by addressing the following questions: what animal species and body parts are used? what ailments or diseases are treated with ... | 2015 | 25608977 |
| providing habitat for native mammals through understory enhancement in forestry plantations. | the convention on biological diversity (cbd) expects forestry plantations to contribute to biodiversity conservation. a well-developed understory in forestry plantations might serve as a surrogate habitat for native species and mitigate the negative effect of plantations on species richness. we experimentally tested this hypothesis by removing the understory in monterey pine (pinus radiata) plantations in central chile and assessing changes in species richness and abundance of medium-sized mamma ... | 2013 | 24033701 |
