    (Universidad de Cuenca, 2025-02-10) Alvarez Alvarez, Alan Fabricio; Estrella Bermeo, Carlos Adrián; Gallo Pérez, Abel Antonio
    The study was carried out in the dry forest “Bajada de Chanduy”, located in the province of Santa Elena, Ecuador. The objective of the research was to determine the relative abundance, diversity and activity patterns of medium and large mammals through and large mammals by means of photo-trapping, using 9 Bushnell Prime 24 MP Low-Glow 24 MP Low-Glow cameras were used to monitor from May to August 2024, with an estimated effort of 882 days/trap. effort of 882 days/trap and 370 individual data. Twelve mammal species were recorded, belonging to 8 families and 5 different orders. The most represented orders were Carnivora (37.16%) and Artiodactyla (59.98%). The most abundant species were Dicotyles tajacu, Nasua nasua, and Odocoileus virginianus. The species with the lowest relative abundance index (RAI) was Galictis vittata. The analysis of activity patterns showed that most of the recorded species were diurnal, with activity peaks at 10:00 am, 08:00 am, and 04:00 pm. Among the diurnal species, Nasua nasua and Eira barbara stood out, while nocturnal species included Leopardus pardalis, Dasypus novemcinctus, and Tamandua mexicana. Cathemeral species, such as Dicotyles tajacu and Odocoileus virginianus, were also identified, showing activity during both day and night. The study also evaluated the relationship between activity patterns and lunar phases, without finding significant influence. The findings provide key information for developing measures to help preserve these ecosystems.
