title: DESCUBRIMIENTO DE UNA POBLACIÓN DE PECES CAVERNÍCOLAS EN COLOMBIA. VALORACIÓN AMBIENTAL ORIENTADA A LA CONSERVACIÓN

description: Proyecto orientado a avaluar la presencia de una población de peces que habita en una caverna en la región andina de Colombia – Municipio de La Paz - Santander. El estudio se desarrolla sustentado en exploraciones preliminares realizadas por el investigador principal en la cueva De Gedania de la región de La Paz - Santander en donde se avistaron peces cavernícolas. La zona presenta alto impacto asociados con la contaminación ambiental, actividades agropecuarias y turismo descontrolado. Por tal razón, la Universidad Santo Tomás Sede Villavicencio dentro de la línea de investigación: “Conocimiento, conservación y uso sostenible de los recursos naturales”, apoyo el desarrollo de este proyecto, fomentando los procesos de investigación para buscar respuestas ante la necesidad de producir y aplicar conocimiento relacionado con los recursos naturales asociadas al grupo de investigaciones GRINBIC, de la Unidad de Ciencias Básicas. El resultado de este proyecto demostró la existencia de una población troglóbia de peces pertenecientes al género Trichomycterus exclusiva de ambientes subterráneos.
