“…The great caecum and hard gut of C. lanatus may be related to a diet based on plant material, as occurs in other frugivorous-herbivorous mammals (CHIVERS & HADLIK 1980, CHARLES-DOMINIQUE et al 1981SCHIECK & MILLAR 1985). The genus Caluromys Allen, 1900 is relatively more specialized in the consumption of fruits, gums and twigs (GRAND 1983, LEITE et al 1994, JULIEN-LAFERRIÈRE 1999, similarly to some primates (CHIVERS & HADLIK 1980, PASSOS 1999. A more frugivorous diet is associated to a small stomach chamber (HILDEBRAND 1995), just as observed here for C. lanatus.…”

The relative proportions of the digestive tract were rarely explored to understand the behaviour and the ecology of neotropical marsupials. In this study, proportions of the digestive tract and diet were compared in seven opossum species. The animals studied were Didelphis albiventris Lund, 1840, D. aurita Wied-Neuwied, 1826, Metachirus nudicaudatus (Desmarest, 1817), Philander frenatus (Olfers, 1818), Lutreolina crassicaudata Desmarest, 1804, Monodelphis sorex (Hensel, 1872) and Caluromys lanatus (Olfers, 1818). Segments of digestive tracts of marsupials were measured and differences were statistically tested by Analysis of Variance and Covariance. Caecum and hard guts were responsible for the main differences among opossums, although all segments differed significantly. Caluromys lanatus was the most specialised species, with a large hard gut and caecum, small stomach and shorter small gut. The large caecum of M. nudicaudatus and the shortest hard gut of M. sorex were also noticed. The arboreal C. lanatus has a well different feeding habit and life style regarding other marsupials studied, such as M. sorex and M. nudicaudatus which are terrestrial, corroborating the results reached.

“…The number of species exploited for food by the three golden-headed lion tamarin groups in Una was higher than previously recorded for any lion tamarin study (Rylands, 1993;Valladares-P´adua, 1993;Dietz, Peres & Pinder, 1997;Passos, 1999;Lapenta et al, 2003). This undoubtedly reflects the extraordinary diversity of tree species in the region (Thomas et al, 1998).…”

The golden-headed lion tamarin Leontopithecus chrysomelas occurs in the Atlantic forest of southern Bahia, Brazil, where shade-cocoa agroforestry (known as cabruca) predominates. The economic decline of the cocoa industry has caused many landowners to convert cabruca into cattle pasture or diversify their plantations with other crops. These and prior anthropogenic disturbances such as habitat fragmentation are threatening lion tamarin persistence. For some lion tamarin groups, cabruca comprises a large part of their home range. Considering these factors, the maintenance of the biological diversity in cabruca favorable to goldenheaded lion tamarins is of considerable interest to their long-term survival. Here we identify plant species that provide food and sleeping sites for the lion tamarins and examine their occurrence in cabruca plantations, in order to investigate alternatives for conservation management practices that benefit both lion tamarins and cabruca. We determined the total number of trees and the frequency of individuals and species used for food and sleeping sites by lion tamarins in Una Biological Reserve, Bahia, from 1998 to 2006. We used this information to compare the richness and frequency of use across habitats (cabruca, mature and secondary) and to create a ranking index considering various components of a tree species' utility to the lion tamarins. Lion tamarins used 155 tree species, 93 for food and 93 for sleeping sites. Fifty-five species were ranked as 'Extremely Valuable,' eight as 'Valuable' and 92 as 'Of Interest.' Of 48 families, Myrtaceae and Sapotaceae were used the most. Cabruca contained fewer individual trees used by lion tamarins, but the highest frequency of use per tree compared with other habitats, indicating the large influence of single trees in these plantations. Using the key tree species identified in our study in the management of cabruca would be of considerable benefit to the long-term survival of lion tamarins

“…Therefore, is expected that howlers would consume less fruit in the dry season in Cerrado/Pantanal (Takahasi & Fina 2004, Lehn 2008, Barbosa-Filho & Araújo 2009, Ferreira et al 2010, when there is a shortage of fruit production, the same seems to be the norm in other biomes as Amazon (Terborgh 1983, Setz 1993, Peres 1994, Pina 1999, Pinto 2002, Pinto & Setz 2004, and Atlantic forest (Rylands 1984, Strier 1987, Passos 1992, Rímoli 2001.…”

The diet and activity patterns of a group of black howler monkeys (Alouatta caraya) were monitored on the left bank of the Aquidauana river over 11 months, from September 2008 to July 2009. The group was composed of eight individuals, two adult males, three females and three immature including subadults and infants. Quantitative data were collected using scan sampling method for 5 minutes with an interval of 15 minutes. The general activities budget (n = 6434 records) was 64.7% rest, 18.5% travel, 10.1% feeding, 4.4% for social behavior and 2.3% for miscellaneous behaviors. The level of rest was similar to patterns of genus (64.7%). The diet (n = 606 records) was composed mainly of leaves (72.8%) and flowers (14.8%) and supplemented by fruits (8.2%) and buds (4.2%). The consumption of reproductive parts of plants, especially flowers, was relatively high by the standards of southerly populations of the species. Members of the group rested significantly less than feed during the rainy season. The diet was marked by the consumption of leaves throughout the study. The consumption was higher in the dry at flowers (17.8%) and fruits in the rainy season (12.9%). It also registered a substantial difference in the behavior of adults and immature individuals, where the first rested significantly more, but spent less time in other categories: food, travel and social interactions. Given this, it's likely that the general budget was under the influence of group's composition, where there was a predominance of mature members, a typical pattern in the genus. The results indicate patterns of behavior and diet that are typical to the genus but marginal for the species. The contrasts can be related mainly to the geographic location of the area of the study, the ecotone Cerrado-Pantanal, and concomitant ecological differences. There is a clear need to continue the studies of A. caraya in the Bororo region, not only for a more systematic assessment of their ecological patterns, but also to contribute to the development of conservation strategies. Keywords: black-howler-monkeys; animal biology; behavioral ecology; activity patterns. (n = 6434 registros) foi de 64,7% para o descanso, 18,5% para o deslocamento, 10.1% para alimentação, 4,4% para o comportamento social e 2,3% para comportamentos não mutuamente exclusivos. O nível de descanso foi similar aos padrões do gênero (64,7%). A dieta (n = 606 registros) foi composta, principalmente por folhas (72,8%) e flores (14,8%) e completada por frutos (8,2%) e brotos (4,2%). O consumo de partes reprodutivas de plantas, principalmente flores, foi relativamente alto para os padrões das populações mais meridionais da espécie. Os membros do grupo descansaram significativamente mais e se alimentaram menos na estação chuvosa em relação à seca. A dieta foi marcada pelo consumo de folhas ao longo do estudo. A ingestão de flores foi significativamente maior na estação seca (17,8%) e a de frutos na chuvosa (12,9%). Foi registrada, também, uma diferença considerável no padrão comportamental d...
