Abstract “Monogamy” and pair bonding have long been of interest to anthropologists and
primatologists. Their study contributes to our knowledge of human evolutionary biology and …

Knowing the density or abundance of primate populations is essential for their conservation
management and contextualizing socio‐demographic and behavioral observations. When …

The subtropical populations of owl monkeys (Aotus) and some lemurs have flexible patterns
that include activity during both day and night. Early studies on the activity patterns of …

In the last few decades, important advances have been made in the knowledge on the
behavioral ecology of pair-living primates such as owl monkeys (Aotus spp.). With the …

Natal dispersal, the movement of individuals from their birthplace to new areas in which they
may breed, is an important aspect of life history that influences processes at the level of the …

Owl monkeys are small, elusive, and nocturnal, making them some of the hardest animals to
survey and study in the wild. We summarize the use of traditional field methods as well as …

Primates show activity patterns ranging from nocturnality to diurnality, with a few species
showing activity both during day and night. Among anthropoids (monkeys, apes and …

Background Long-term research of known individuals is critical for understanding the
demographic and evolutionary processes that influence natural populations. Current …

Polygynous animals are often highly dimorphic, and show large sex-differences in the
degree of intra-sexual competition and aggression, which is associated with biased …

Understanding the evolution of mating systems, a central topic in evolutionary biology for
more than 50 years, requires examining the genetic consequences of mating and the …
