Mitochondrial cytochrome oxidase II (COII) gene sequences (549 base pairs) were used to investigate the taxonomic relationships among 12 marmoset (Callithrix, Cebuella and Mico) taxa. A large number of substitutions were found in the third base codon positions, providing a strong phylogenetic signal in a gene coding a conserved protein. Despite the significant affinity between the 2 Amazonian genera Cebuella and Mico, found in recent molecular studies, the analysis presented here did not resolve convincingly the phylogenetic relationships between the 3 genera. Mico nevertheless formed 3 distinct clades, reflecting a basic division of species groups based on geographic distribution (east or west of the Rio Tapajós) rather than morphology (presence or absence of auricular hair). This supports the taxonomic distinction of the allopatric emiliae forms. In Callithrix, Callithrix aurita forms a distinct clade, but the remaining morphotypes form a somewhat contradictory cluster, possibly resulting from an extremely rapid radiation.

“…Essa espécie é predominantemente insetívora, sendo menos gomívora que as outras espécies do mesmo gênero (MUSKIN 1984, FERRARI et al 1996. A persistência deste sagüi em fragmentos florestais de pequena área deve-se à grande disponibilidade de insetos que proliferam nos emaranhados de cipós e lianas (MUSKIN 1984, BRANDÃO & DEVELEY 1998, mas sua baixa densidade poder ser reflexo de alta pressão de predação.…”

Foram realizadas transecções lineares em um pequeno fragmento de Floresta Atlântica semidecídua, a fim de se estimar densidade e tamanho populacional de primatas. A Mata São José possui uma área de 230 ha e está localizada entre Rio Claro e Araras (Estado de São Paulo, sudeste do Brasil). Este fragmento florestal abriga 23 espécies de mamíferos não - voadores, distribuídos em sete ordens e 13 famílias. De julho de 1999 a janeiro de 2001, foram percorridos 125 km e três espécies de primatas foram registradas. As densidades populacionais foram estimadas com base no software Distance. A espécie de primata que apresentou maior densidade foi o macaco-prego Cebus nigritus (Goldfuss, 1809) (Cebidae) (24,5 indivíduos/ km², variando entre 19,6 e 32,6 indivíduos/ km²). Para o sauá Callicebus nigrifrons (Spix, 1823) (Pitheciidae) e o sagüi-da-serra-escuro Callithrix aurita (É. Geoffroy, 1812) (Callitrichidae) foi calculada uma densidade de 3,5 indivíduos/ km² (variando entre 2,8 e 4,6 indivíduos/ km²). A população total de macaco - prego estimada foi de 56 indivíduos (variando de 45 a 75 indivíduos), bem como a população total de sauá e sagüi-da-serra-escuro foi de oito indivíduos (variando de seis a 10 indivíduos). O sauá e o sagüi-da-serra-escuro estão inclusos na lista nacional das espécies da fauna brasileira ameaçadas de extinção no Brasil, considerados vulneráveis à extinção, mas esses dois primatas ainda persistem na Mata São José, ainda que em baixa densidade populacional. Estas espécies estão correndo risco de extinção local, pois o pequeno tamanho das populações as torna mais suscetíveis a efeitos estocásticos, depressão genética por endocruzamento e variações ambientais. A translocação destas espécies de primatas é a única medida de manejo plausível que pode evitar a extinção local destas populações de primatas.

“…Relatively high rates of gum feeding have already been recorded in the Atlantic Forest of northeastern Brazil, both for common marmosets (∼62% of feeding bouts) [16] and for other callitrichids (up to 87% of their feeding bouts [21][22][23][24]). The values presented here are, nevertheless, some of the highest ever reported for gum feeding, being higher even than those reported for common marmosets in dryscrub Caatinga forest (around 50% of the feeding bouts) [30], and for C. penicillata in the xeromorphic semideciduous woodlands of the Cerrado and Cerradão (between 45% and 65%) [34].…”

We evaluate the impact of very small and isolated forest fragments on the common marmosets home range, diet, and activity patterns, in the northeastern Atlantic Forest of Brazil. Three groups were studied in three forest fragments, from January to October 2010, totaling 360 hours of observations and 1,080 field-hours. Systematic observations were recorded using Instantaneous Scan Sampling, and a checklist of the items exploited was built through ad libitum observations. We recorded location of the groups and calculated home range. We recorded 11,639 scans and 236 ad libitum feeding records. 83.4% ( = 10) of food items were plant species, the only animal protein was from insects ( = 2; 16.6%), and the diet was based almost exclusively on gums. Mean home range was 5.5 ha, mean daily path length was 1,167 meters, and no differences were detected between seasons. Resting dominated their activity budget and varied between seasons. Common marmosets survived in this environment through a remarkable increase in their exploitation of tree gums (up to 98% of their feeding bouts) to compensate for the lack of food, in home ranges slightly larger than in the literature. Thus, they travelled and foraged less than expected and rested more since food was easily obtained.
