RESUMO
We investigated Malassezia spp. in external ear canal and haircoat of free-ranging golden-headed lion tamarins (Leontopithecus chrysomelas). A total of 199 animals were restrained, and 597 clinical samples were collected. After the amplification of the 26S ribosomal gene by polymerase chain reaction (PCR), the RFLP technique was performed. Two additional PCR protocols were performed in 10 randomly selected strains. Malassezia sp. was isolated in 38.2% (76/199) of the animals and 14.6% (87/597) of the samples; all strains were lipodependent. The 10 sequenced strains showed a high identity with Malassezia japonica, species described in man, but not in animals, so far.

Little is known about frugivory of epiphytes. We investigated diurnal frugivores consuming Aechmea depressa, an endemic species from Southern Bahia, Brazil, through 67 hours of observation on three fruiting individuals. Infructescences were visited for 2 percent of the time and only by golden-headed lion tamarins (GHLTs; Leontopithecus chrysomelas). Aechmea depressa invests on physical defense to retain fruits for prolonged periods, however, GHLTs used their small size and dexterity to remove rigid bracts and extract fruits from the infructescence. Prior studies indicate GHLTs disperse Aechmea seeds. Given the low visitation rates and probability that few frugivores successfully manipulate A. depressa fruits, we suggest that GHLTs are extremely important to maintaining the populations of this bromeliad species.
Pouco se sabe sobre a frugivoria em plantas epífitas. Nós investigamos os frugívoros diurnos de Aechmea depressa, uma espécie endêmica do Sul da Bahia através de 67 horas de observação dos frutos de três indivíduos. As infrutescências foram visitadas em 2 por cento do tempo somente por micos-leão-da-cara-dourada (MLCD; Leontopithecus chrysomelas). Aechmea depressa investe na defesa física para reter seus frutos por períodos prolongados entretanto, o MLCD utiliza seu pequeno tamanho e extrema destreza para remover as brácteas rígidas e extrair os frutos da infrutescência. Estudos prévios indicam que os MLCDs dispersam sementes de espécies de Aechmea. Baseando-se na baixa taxa de visitação e na probabilidade de que poucos frugívoros manipulem adequadamente os frutos de A. depressa, nós sugerimos que os MLCD sejam extremamente importantes para manter as populações desta espécie de Bromeliaceae.
