Resumen
En el transcurso de los meses de mayo 2016 a junio 2017 se colectaron quirópteros dentro del Bosque Protector Cerro El Paraíso. Se capturaron un total de veinte individuos pertenecientes a dos familias (Phyllostomidae y Molossidae), y tres especies; de las cuales Molossus molossus fue la que presento más individuos. Presentando una baja diversidad. En cada muestreo se tomaron variables ambientales; Nubosidad, Velocidad del Viento, Altura e Intensidad de brillo en el cielo nocturno (Sky Glow), para relacionarlas con las capturas y demostrar en qué grado ésta depende de las variables ambientales. Como resultado al relacionar las variables ambientales con la captura de especies refleja que la Nubosidad se relaciona positivamente con las capturas en mayor proporción (+0,0240), al igual que Velocidad de viento, pero en menor proporción (+0,0027), y Altura (-0.0190) se relaciona de manera negativa con las capturas de especies, como Sky Glow (-0,0055) lo que nos expresa que a menor intensidad de brillo de cielo nocturno (Sky Glow) mayor será la abundancia de captura. Se concluyó en base a los resultados que el Bosque Protector Cerro El Paraíso no presenta los criterios técnicos para declararse en un AICOM.
In the course of the months of May 2016 to June 2017, bats were collected inside the Cerro El Paraíso Protected Forest. A total of twenty individuals belonging to two families (Phyllostomidae and Molossidae), and three species were captured; of which Molossus molossus was the one that presented more individuals. Presenting a low diversity. In each sample, environmental variables were taken; Cloudiness, wind speed, height and brightness intensity in the night sky (Sky Glow), to relate them to the captures and to show the degree to which it depends on the environmental variables. As a result, the relation between the environmental variables and the species capture reflects that the cloudiness is positively related to the catches in the highest proportion (+0,0240), as well as Wind speed, but in a lower proportion (+0.0027), and height (-0.0190) is negatively related to species catches, such as Sky Glow (-0.0055) which tells us that the lower intensity of night sky brightness (Sky Glow) will be the abundance of capture. It was concluded from the results that the Cerro El Paraíso Forest Protector does not present the technical criteria for declaring itself in an AICOM.
