Diet Overlap and Foraging Activity between Feral Pigs and Native Peccaries in the Pantanal
Inter-specific competition is considered one of the main selective pressures affecting species distribution and coexistence. Different species vary in the way they forage in order to minimize encounters with their competitors and with their predators. However, it is still poorly known whether and how native species change their foraging behavior in the presence of exotic species, particularly i...
متن کاملEvaluation of genetic variability in the collared peccary Pecari tajacu and the white-lipped peccary Tayassu pecari by microsatellite markers
In this study, the microsatellite technique was used to evaluate the genetic variability in populations of collared and white-lipped peccaries kept in captivity. Six primers developed for domestic pigs were used and amplified in both species. They revealed the presence of five polymorphic loci and one monomorphic locus. The polymorphic loci included 4 of the 16 alleles in collared peccaries, an...
متن کاملFate of native and introduced seeds consumed by captive white-lipped and collared peccaries (Tayassu pecari, Link 1795 and Pecari tajacu, Linnaeus 1758) in the Atlantic rainforest, Brazil.
We studied the role of white-lipped and collared peccaries (Tayassu pecari and Pecari tajacu) as seed predators and dispersers in the Atlantic rainforest of Brazil. The Atlantic rainforest ecosystem is highly threatened and has experienced dramatic declines in its populations of large mammals. Local extinctions can disrupt essential plant-animal interactions such as seed dispersion and seed pre...
متن کاملSerosurvey of anti- Leptospira sp. and anti- Toxoplasma gondii antibodies in capybaras and collared and white-lipped peccaries.
INTRODUCTION: Brazilian native species are reemerging as increasingly free-ranging populations. METHODS: Sera from 31 capybaras (Hydrochoerus hydrochaeris) and 28 peccaries (Pecari tajacu and Tayassu pecari) were tested for anti-Leptospira and anti-Toxoplasma gondii antibodies using microscopic seroagglutination test. RESULTS: Nineteen percent of free-ranging and 10.0% of captive capybaras,...
متن کاملThe white-lipped peccary Tayassu pecari
White-lipped peccaries are non-seasonal breeders in South America, but little is known about their reproduction in Central America. There are few studies about the sex ratio of this species in the field. We studied the reproduction and sex ratio of white-lipped peccaries during 200 hours of field observation of four radiomarked and two unmarked herds, from July 1996 to April 1997, in Corcovado ...
