Abstract (en):
This paper is an update to the knowledge on the diversity of this departmentâs herpetofauna and an analysis
of the distribution of species richness according to Holdridge´s ecological life zone system, altitudinal ranges and ecoregions. To meet this aims, records were taken by researchers from the available literature, biological collections, observations and field recordings. Based on the obtained data, analyzes of eta richness and diversity were performed. There were a total of 333 species recorded (187 amphibians and 146 reptiles). We found that the greatest species richness of herpetofauna is concentrated in the Pacific region. Species richness of both reptiles and amphibians decreased with increasing altitude range. Furthermore, the life zone with the highest species richness was the Premontane rain forest with warm transition. The areas that presented the highest species richness have features that enable a high diversity of species; however, it must also be taken into account that these areas are the ones with the biggest land extension within Valle del Cauca (Colombia), and that they are where most studies have been focused.
Abstract (es):
El presente trabajo es una actualización al conocimiento de la diversidad de herpetofauna en regiones del Valle
del Cauca (Colombia) y un análisis de la distribución de la riqueza de especies en zonas de vida ecológicas
según Holdridge, intervalos de altura y ecorregiones. Para cumplir con este objetivo se tomaron los registros de fuentes bibliográficas, colecciones biológicas, observaciones y registros de campo por parte de investigadores. Con base en la información obtenida se realizaron análisis de riqueza y diversidad beta. Se registraron de 333 especies (187 anfibios y 146 reptiles). Se encontró que la mayor riqueza de herpetofauna se concentra en la región Pacífica; la riqueza de especies tanto de anfibios como de reptiles disminuyó a medida que aumentó el intervalo altitudinal y la zona de vida con mayor riqueza de especies fue el bosque pluvial premontano (bp-PM) con transición cálida. Las zonas que mayor riqueza presentaron cuentan con características que posibilitan una gran riqueza de especies; sin embargo, también se debe tener en cuenta que son las de mayor proporción en el Valle del Cauca y en las cuales se han enfocado la mayoría de los estudios.
