Cooperative relationships among male primates are emerging as an important aspect of primate social behavior. What remains unclear is the extent to which male associations with coresident males vary within species, and what social and demographic factors drive these associations. This information provides an important contribution to our understanding of how cooperative relationships play an adaptive role in the evolution of male social and reproductive strategies. To examine the nature of male associations and the influence of social and demographic factors, including rank and age, we collected 1751 h of focal behavioral data on adult males in two large multimale–multifemale groups of mantled howlers (Alouatta palliata) at La Pacifica, Costa Rica. Both groups inhabited upland forest area, were of similar size and sex ratio, and exhibited strongly linear male hierarchies. Based on observed spatial associations within 3 m proximity, dyadic patterns varied from strongly preferred to strongly avoided associations that were largely consistent among dyads over the study period. In contrast to reports from other mantled howler study sites, neither rank nor age differences among males predicted whether dyads spent any time in proximity to one another, nor the amount of time in proximity. However, higher-ranked males within dyads were more likely to maintain close proximity than their lower-ranked counterparts. Our results provide important data on the nature of male associations within mantled howler groups with linear dominance relationships, and are suggestive of the adaptive value of cooperative relationships.

Alouatta Palliata

El mono congo (Alouatta palliata) es una de las cuatro especies de primates de Costa Rica cuyo estatus de conservación la ubica como especie en peligro de extinción. La principal amenaza que enfrentan los monos congo es la pérdida del hábitat y la fragmentación del bosque situación que expone a sus poblaciones a problemas relacionados con el aislamiento, la pérdida de conectividad en el paisaje y un ambiente modificado por infraestructuras de origen antropogénico. Se expone la relevancia de atender la problemática que experimentan los monos congo en pro de su bienestar mediante el trabajo interinstitucional coordinado, la aplicación de la robusta legislación costarricense y el conocimiento ecológico existente de  la especie.

Piedras Blancas National Park, in southern Costa Rica, is an important component of two biological corridors connecting the Osa Peninsula (Corcovado National Park) and La Amistad International Park. Understanding the mammal community composition of Piedras Blancas will provide baseline data to evaluate the success of conservation efforts. We used camera traps and opportunistic observations to describe the medium-sized and large mammals of the park. We deployed camera traps for 1,440 trap nights (2016-2018). We detected 19 mammal species from seven orders and 13 families. Five species are globally threatened: Leopardus wiedii (Schinz, 1821), Saimiri oerstedii (Linnaeus, 1758), Ateles geoffroyi (Kuhl, 1820), Alouatta palliata (Gray, 1849), and Tapirus bairdii (Gill, 1865). We did not detect two locally threatened species, Panthera onca (Linnaeus, 1758) and Tayassu pecari (Link, 1795). Our research highlights a need for critical conservation work within the proposed biological corridor to support Costa Rica’s most threatened wildlife.
