“…This creates a scenario where captive populations, not suitable for reintroduction, keep increasing each year due to uncontrolled reproduction. Finally, in Misiones, the possible release of individuals from captivity, mostly from another congeneric species (S. cay), could potentially lead to hybridization and, consequently, decrease the population viability of the native species, S. nigritus [147]…”

There are five different primate species inhabiting widely distinct ecoregions in Argentina. Each of them faces various threats in terms of conservation and conflicts that hamper their ability to coexist with human populations. We present here some of the drivers known to be the causes of conflicts between humans and primates in the southernmost area of distribution of Latin American primates. We focus our synthesis on two of the biggest sources of conflict: the effects of different anthropogenic disturbances, and human misconceptions concerning the role of primates in the ecosystem. In each section, we briefly characterize the conflicts worldwide and then provide specific cases and examples from Argentina. In the last part of the manuscript, we further describe some ongoing national and regional educational, research, and conservation approaches to mitigate those effects.

Evidence of an infanticide in black-horned capuchin monkeys (Sapajus nigritus) in an Atlantic Forest remnant in Argentina

An infanticide is a rare event but has important impact in primate populations. The black-horned capuchin monkey, Sapajus nigritus, is a native species from the Atlantic Forest. Previous reports of infanticide in this species are explained with the 'sexual-selection' hypothesis, and occur in large groups and after a dominant male replacement. Here we provide evidence of a new case of infanticide by a non-identified member of a wild group of S. nigritus, in a remnant of the Atlantic Forest under anthropogenic disturbance. Our study group (30-35 individuals) overlapped its home range with other species' groups in an isolated forest fragment (570 ha). This primate overcrowding in a small area may have increased social intolerance and aggression. In this regard, this infanticide event may be associated to a non-adaptive explanation such as the social pathology hypothesis.
