Abstract (en):
Nowadays, the high-Andean and paramo ecosystems from Colombia are threatened as a result of habitat degradation, which has caused that some groups, like amphibians and reptiles, are under some threat category. It was done the first analysis of species richness in the Fúquene river basin, in the department of Cundinamarca, in different habitats in transects between 2600 and 3100 m a.s.l. It was performed a systematic sampling, during the day and at night, looking for amphibians and reptiles in three characteristic habitats: paramo, riparian forest and high-Andean forest. There were found two species of frogs and five of reptiles in the study area, It was reached a sample representation of 100% in each habitat. Although there are not previous records of amphibian and reptiles in the study area, the results were compared with a check list for near localities in similar elevations. The habitat degradation and contamination, caused by agricultural activity and livestock, may be related with the low diversity of amphibians and reptiles in the region.
Abstract (es):
En la actualidad los ecosistemas altoandinos y de páramo en Colombia se encuentran amenazados como resultado de la degradación del hábitat, lo que ha causado que organismos como anfibios y reptiles estén bajo alguna categoría de amenaza. Se realizó el primer análisis de la riqueza de especies en la cuenca del río Fúquene en el departamento de Cundinamarca, en diferentes hábitats que comprenden un transecto entre los 2600 y 3100 m s.n.m. Se realizaron muestreos sistemáticos durante el día y la noche, en busca de anfibios y reptiles en tres hábitats característicos de la zona: páramo, bosque ripario y bosque altoandino. Se registraron dos especies de anuros y cinco de reptiles, con una representatividad de muestreo del 100% en cada hábitat. Aunque no hay registros previos de anfibios y reptiles para la zona, se comparó con un listado de especies que se construyó para localidades cercanas a elevaciones similares. Factores como la alteración del hábitat y la contaminación, producto de la actividad agrícola y ganadera, pueden estar vinculados con la baja diversidad de anfibios y reptiles en la región.
