Number of adult females in a group affects infant motor development of a cooperative breeding primate (Callithrix jacchus)
Should I store, or should I sync? The breeding strategy of two small Neotropical primates under predictable resource availability
Balancing contest competition, scramble competition, and social tolerance at feeding sites in wild common marmosets ( Callithrix jacchus )
Models of primate sociality focus on the costs and benefits of group living and how factors such as rank, feeding competition, alliance formation, and cooperative behavior shape within‐group social relationships. We conducted a series of controlled field experiments designed to investigate how resource distribution (one or three of four reward platforms) and amount of food on a reward platform affected foraging strategies and individual feeding s…
Trait variation and trait stability in common marmosets ( Callithrix jacchus) inhabiting ecologically distinct habitats in northeastern Brazil
Understanding the set of factors that promote and constrain a species’ ability to exploit ecologically distinct habitats is central for addressing questions of intraspecific variability in behavior and morphology. In this study, we compared newly collected data with published data on body measurements, group size and composition, daily path length, home range, and reproductive output in wild common marmosets naturally inhabiting two contrasting e…
Terrestrial Behavior in Titi Monkeys (Callicebus, Cheracebus, and Plecturocebus)
People's perception on animal welfare
Understanding peoples' perception on animal welfare is vital to promote people awareness and changes in attitudes towards this subject. Here we present a short review on public perception of animal welfare in different instances and the factors influencing each one of them. While the great public concern towards farm and laboratory animals resulted in increased efforts to assess animal welfare in these instances, less attention has been given to …
Estimating primate population densities
Accurate measures of animal population densities are essential to assess their status, demography, and answer ecological questions. Among several methods proposed to collect abundance data, line transect sampling is used the most. The assumptions required to obtain accurate density estimates through this method, however, are rarely met when studying primates. As most primate species are vocally active, density estimates can be improved by associa…
Sleeping above the enemy
The costs imposed by predation may result in behavioral adaptations to reduce mortality risk, including the choice and use of sleeping sites. The threat of predation, however, is rarely the sole force shaping sleeping site choice, which is likely to reflect other factors such as foraging needs as well. Here we describe the use of sleeping sites by three groups of small Neotropical monkeys, the black-fronted titi monkeys (Callicebus nigrifrons), a…
Geographic comparison of plant genera used in frugivory among the pitheciids Cacajao , Callicebus , Chiropotes , and Pithecia
Pitheciids are known for their frugivorous diets, but there has been no broad-scale comparison of fruit genera used by these primates that range across five geographic regions in South America. We compiled 31 fruit lists from data collected from 18 species (three Cacajao, six Callicebus, five Chiropotes, and four Pithecia) at 26 study sites in six countries. Together, these lists contained 455 plant genera from 96 families. We predicted that 1) c…
Playback responses of socially monogamous black‐fronted titi monkeys to simulated solitary and paired intruders
Many birds and primates use loud vocalizations to mediate agonistic interactions with conspecifics, either as solos by males or females, or as coordinated duets. The extensive variation in duet complexity, the contribution of each sex, and the context in which duets are produced suggest that duets may serve several functions, including territory and mate defense. Titi monkeys (Callicebus spp.) are believed to defend their home range via solo loud…
Vocal behavior of black‐fronted titi monkeys ( Callicebus nigrifrons )
Loud calls can be heard over long distances due to their high amplitude and low frequency. These calls are commonly used for both within- and between-group communication in many bird and primate species. In the Neotropics, mated pairs of socially monogamous titi monkeys (genus Callicebus) emit conspicuous, coordinated loud calls. These vocalizations appear to play a role in territorial defense, a hypothesis derived from studies of only three of t…
