Resumen
Los mamíferos son vertebrados que presentan pelos, tienen temperatura corporal
constante, y cuyas hembras desarrollan glándulas mamarias con las cuales producen
leche para alimentar a sus crías. La mayor diversidad de mamíferos en Ecuador se
encuentra en los bosques húmedos del Trópico Oriental o Amazónico. El Área Nacional
de Recreación Isla Santay (ANRIS), con su variedad de recursos naturales y tipos de
ecosistemas es un elemento esencial para la protección y el mantenimiento de la
mastofauna de la región Occidental. En el ANRIS se analizó, identificó y comparó la
riqueza y abundancia de mamíferos, en zonas con distintos niveles de perturbación, se
dividió el área de muestreo en dos zonas: intervenida e intangible, utilizando métodos
directos e indirectos para el monitoreo de las especies de mamíferos y complementando
con la instalación de cámaras trampa. Entre los resultados, se logró registrar siete
especies para ambas. La mayor abundancia se registró en la zona intangible y la especie
más abundante fue Leopardus pardalis entre las zonas de muestreo. Adicionalmente,
Philander opossum, Sigmodon peruanus y Lontra longicaudis son nuevos registros,
mientras que, Tamandua mexicana, Lontra longicaudis y Odocoileus peruvianus son
identificadas como objetos de conservación.
Mammals are vertebrates that present hairs, maintain constant their corporal temperature, and its females develop mammary glands to produce milk and feed their offspring. The greatest diversity of mammals in Ecuador is found in the humid forests of the Eastern region or Amazonian Tropics. The Santay Island National Recreation Area (ANRIS for its spanish acronym), has a variety of natural resources and types of ecosystems, which are essential elements for protection and maintenance of the mammals fauna of the Western region. At the ANRIS, the richness and abundance of mammals were analyzed, identified and compared, between zones with different levels of disturbance, the division of the sampling area into two zones was achieved: intangible and intervened zones, using direct and indirect methods for the monitoring of the species and complementing with the installation of trap cameras. Among the results, it was possible to register seven species in two zones. The highest abundance was recorded in the intangible zone, and the most abundant species was Leopardus pardalis in both sampling areas. Additionally, Philander opossum, Sigmodon peruanus and Lontra longicaudis represent new records for the locality, while Tamandua Mexicana, Lontra longicaudis and Odocoileus peruvianus are suggested identified as conservation priority species for conservation.
