Anthropogenic Habitat Modification, Tourist Interactions and Crop-Raiding in Howler Monkeys
Abstract
In this chapter, we review how anthropogenic disturbance specifically impacts members of the genus Alouatta, one of the most geographically expansive and ecologically flexible of platyrrhine groups. This report initiates with a brief discussion of the use of matrix landscapes, the effects of ecotourism, and the potential for crop-raiding by howler monkeys. We then present three case studies of howler monkey responses to these challenges. We found that tourism in Suriname leads to greater travel and foraging time and poorer health for A. macconnelli. A. palliata in Costa Rica living in an agricultural matrix respond to habitat modification through active crop-raiding, and A. pigra in Mexico provide an illustration of how to evaluate remnant monkey populations for potential ecotourism. The chapter concludes with recommendations for encouraging shared landscapes with howler monkeys, including ways to minimize crop damage by monkeys and ways to encourage sustainable, conservation-based ecotourism.

En este capítulo, revisamos cómo los disturbios antropogénicos impactan de manera directa a los miembros del género Alouatta, los cuales son platirrinos con una amplia distribución geográfica y notable plasticidad ecológica para adaptarse a su entorno. Iniciamos con una breve discusión sobre el uso de la matriz del paisaje, un análisis de los efectos del ecoturismo y el papel de los monos aulladores en el uso de los recursos que contienen los agrosistemas. Presentamos tres casos de estudio en los que se muestra la respuesta de los monos aulladores a estos desafíos. Encontramos que el turismo en Surinam promueve un mayor tiempo de viaje y forrajeo en A. macconnelli, además de provocar deficiencias en la salud de los individuos. Por otra parte, individuos de A. palliata que habitan en una matriz de bosque mezclado con tierras dedicadas a la agricultura en Costa Rica, responden a la modificación del hábitat a través del consumo activo de frutos cultivados. Poblaciones de A. pigra en México nos permiten ilustrar cómo evaluar el estado de conservación de las poblaciones de monos remanentes y su uso potencial en ecoturismo. El capítulo concluye con recomendaciones para promover paisajes antropogénicos compartidos con los monos aulladores, incluyendo estrategias para minimizar el daño en las cosechas por estos primates, así como acciones para favorecer el ecoturismo sostenible.
