Thousands of plant species rely on ants to disperse their seeds, including many South American epiphytes and vines, which, apart from minimizing competition among seedlings, may also reduce competition among different plant species (Handel & Beattie, 1990). The lianas of the Genus Strychnos (Loganiaceae) are recognized as having fruits with highly poisonous seeds containing strychnine in the in...

Tamarins, small Neotropical primates of the genera Saguinus and Leontocebus, have a mainly frugivorous-faunivorous diet. While consuming pulp high diversity fruit species, they also swallow seeds void them intact, thus acting as seed dispersers. Here we compare different aspects dispersal ecology tamarins with that large from Ateles (spider monkeys) Lagothrix (woolly monkeys). Due to their body...

Increased attention towards the Neotropical cats Leopardus guttulus and L. geoffroyi was prompted after genetic studies identified the occurrence of extensive hybridization between them at their geographic contact zone in southern Brazil. This is a region where two biomes intersect, each of which is associated with one of the hybridizing species (Atlantic Forest with L. guttulus and Pampas with...

Killed herpesvirus cancer vaccines were prepared by inactivation of oncogenic herpesviruses (Herpesvirus saimiri and Herpesvirus ateles) with heat and formaldehyde. The killed vaccines, which are not free of viral nucleic acid, were safe in 121 vaccinated monkeys of 4 different species. Some of these monkeys have now been under observation for 2 years. The vaccines induced high titers of specif...

Leptospirosis is an infectious disease that affects practically all domestic and wild animals, which can become carriers and, as a consequence, will contribute to the spread of microorganism in nature. The present study aims detect occurrence leptospirosis against by microscopic serum agglutination test animals at Zoo Centro Universitário da Amazônia (ZOOUNAMA). 26 adult both sexes following sp...

Abstract Anoura carishina was described based on cranial and dental morphology, but the original analyses did not include latidens , a similar species of . We used morphological, morphometric, genetic to evaluate taxonomic identity A. carishina. performed principal components analysis correspondence between morphological groups for 260 specimens large-bodied ( geoffroyi peruana ), statistically...
