Resumen
Los mamíferos grandes y medianos cumplen roles ecológicos importantes, de los cuales su perdida representaría impactos negativos para el ecosistema; ya que, son esenciales para la salud y equilibrio de los sistemas biológicos. El presente estudio tuvo como objetivo evaluar los patrones de actividad y frecuencia relativa de mamíferos grandes y medianos en la Reserva Ecológica Manglares Churute en la provincia del Guayas. Por medio de método de fototrampeo, se registró un total de 16 especies, de las cuales solo cuatro cumplieron con los criterios de inclusión para el análisis de patrones temporales. Las especies más abundantes son Dasyprocta punctata con un Índice de abundancia relativa de 12.12 categorizándose como diurna con picos de actividad durante las 06:00-17:00h, seguido de Nasua nasua (IAR=4.87) siendo diurna (05:00-17:00h), entre las especies catemerales esta Sylvilagus daulensis (1.75) con actividad entre 18:00-05:00h y 13:00h; finalmente, Leopardus pardalis (1.37) como especie nocturna (22:00-05:00h).
Large and medium-sized mammals play an important ecological role, which, if lost, would represent negative impacts for the ecosystem since this group is essential for the health and balance of biological systems. The main objective of this study was to evaluate the activity patterns and relative frequency of large and medium-sized mammals in the Churute Mangroves Ecological Reserve in the province of Guayas. A total of sixteen species were registered by photo-trapping, of which only four met the inclusion criteria for the analysis of temporal patterns. The most abundant species of the reserve were Dasyprocta punctata with a relative abundance index of 12.12, being categorized as diurnal with peaks of activity during 06:00h-17:00h., followed by Nasua nasua (IAR= 4.87) being diurnal (05:00-17:00h), among the cathemeral species is Sylvilagus daulensis (1.75) with activity between 18:00-05:00h and 13:00h; finally, Leopardus pardalis (1.37) as nocturnal species (22:00-05:00h).
