13. Comunidade de mamiferos não-voadores de um fragmento de floresta Atlantica semidecidua do municipio de Campinas, SP
The population richness, composition, abundance and density of non-volant mammals of mata Ribeirão Cachoeira forest, a 230 ha semideciduous forest fragment in the outskirts of Campinas, São Paulo, were studied between 2001 and 2003. The main objective was to evaluate the importance of this forest fragment to the local and regional conservation of the nativ

14. Survey of intestinal helmints in brown-howler-monkey, Alouatta guariba (Primates, Atelidae), at Ribeirão Cachoeira Forest, in the District of Souzas, Campinas city, SP / Levantamento de helmintos intestinais em bugio-ruivo, Alouatta guariba (Primates, Atelidae), na Mata de Ribeirão Cachoeira, no distrito de Souzas/Campinas, SP
Durante o período de agosto de 2003 a julho de 2004 foram realizadas coletas mensais de fezes de bugios-ruivos, Alouatta guariba (Primates, Atelidae), em um fragmento de Floresta Atlântica Semidecídua, a Mata Ribeirão Cachoeira, situada no Distrito de Souzas ? Campinas/SP, com 234 hectares. As fezes foram coletadas ao longo de duas trilhas longitudinais

15. Aspectos morfológicos do aparelho reprodutor em bugios (Alouatta guariba clamitans e Alouatta caraya): o modelo feminino / Morphological aspects of the reproductive tract of howler monkey (Alouatta guariba clamitans and Alouatta caraya): the female model
O Brasil tem cerca de 133 espécie s e subespécie de primatas, das quais cerca de 35% são endêmicas. A ocupação e destruição cada vez maior dos ambientes naturais somadas a caça e o comércio ilegal de animais silvestres deixou algumas espécies de primatas seriamente ameaçadas de extinção. O presente estudo trata da morfologia do aparelho reprodu

16. O destino pos-dispersão das sementes do caquizinho-do-mato (Diospyros inconstans) ingeridas pelo bugio-ruivo (Alouatta guariba clamitans) em uma floresta subtropical no sul do Brasil
The main benefit frugivorous vertebrates provide to plants is the distribution of their seeds in sites favorable for survival. The dispersal efficiency may be determined by the quality of the dispersal site, which directly influences post-dispersal seed and seedling survival. However, very few studies have investigated the relations between disperser activit

18. Ecologia do Alouatta fusca em floresta de encosta e de restinga no Sul do Brasil
I compared the activities in groups of the brown howler monkey A/ouatta fusca in forests growing on hillsides and on a sand flat bordering Lago Guaíba in Porto Alegre, RS, near its southern range limit. The hillside forest is taller and has a higher species diversity of trees and only two tree species Ficus organensis and Coussapoa microcarpa (Moraceae) com

19. Loss of Olfactory Receptor Genes Coincides with the Acquisition of Full Trichromatic Vision in Primates
Olfactory receptor (OR) genes constitute the molecular basis for the sense of smell and are encoded by the largest gene family in mammalian genomes. Previous studies suggested that the proportion of pseudogenes in the OR gene family is significantly larger in humans than in other apes and significantly larger in apes than in the mouse. To investigate the pro

20. Origins and antiquity of X-linked triallelic color vision systems in New World monkeys
It is known that the squirrel monkey, marmoset, and other related New World (NW) monkeys possess three high-frequency alleles at the single X-linked photopigment locus, and that the spectral sensitivity peaks of these alleles are within those delimited by the human red and green pigment genes. The three alleles in the squirrel monkey and marmoset have been s
