Geographic Distribution of Owl Monkeys

Owl Monkeys

Part of the book series: Developments in Primatology: Progress and Prospects ((DIPR))

Abstract

The owl monkeys, genus Aotus, are among the most widely distributed of all platyrrhine genera. The 13 currently recognized taxa are found in Argentina, Bolivia, Brazil, Colombia, Ecuador, Panama, Paraguay, Peru, and Venezuela. They range from lowland tropical moist and dry forests to over 3000 m.a.sl. in the cloud forests of the Andes. Owl monkeys appear to be sufficiently flexible to persist in anthropogenically altered habitats and fragmented forest patches. Here we gathered 1,703 owl monkey localities from a wide range of published and unpublished sources, making the most comprehensive database to date. These records were used to map the distributions of all owl monkey taxa based on our current understanding of the genus. Our knowledge is still limited in many areas where records are lacking, and we caution that all species IDs and maps be treated as tentative until the wide-ranging employment of genetic testing is available.

Marsh for additional localities. Also, the teams at Neotropical Primate Conservation (NPC) UK, NPC Peru, NPC Colombia, and NPC Argentina for their dedication to conservation in the field. NPC survey work included in this chapter has been carried out with the permission of countless local communities and authorities, for which we are eternally grateful. RA wishes to thank the Proyecto Peruano de Primates no Humanos in Iquitos for the facilities granted as well as the consulting agency ERM-Peru for providing the opportunity to participate in wildlife evaluations as part of environmental impact studies for oil exploitation in different lots and the concessionaires of these lots, Plus Petrol and Repsol, respectively, for their support. Also, my thanks to Conservation International for its support through the Primate Action Fund for expeditions in order to evaluate primates in montane forests. XCP wishes to thank the Sanchez-Rey, Novoa, and Enciso families for their long-term support and permission to work on their farms, as well as Fundación William Barrios, Cumaral Biodiversa, Fundación Camaná, and Finca El Silencio for their support and collaboration on collecting primate data.
