dc.description.abstractAstroblepid species inhabit the Andean Cordilleras in South America. Their habitat has undergone a rapid transformation to the unimaginable levels of degradation since ancient times. State of knowledge on the habitat perturbation and the concomitant extirpation of endemic astroblepid species is scarce. The Andes Cordilleras are characterized by fertile soil and as a result of that, vast regions are transformed for agriculture and pasture for cattle. These processes require the use of water obtained from creeks and springs that causes remarkable changes of the natural configuration of these water systems and the disappearance of the fish fauna together with the zooplankton and aquatic flora. Despite these human actions, some species of Astroblepus may have the ability to respond to the rapid habitat transformation enabling them to survive. In this paper we will discuss the incidence of habitat perturbation in a localized stream segment on the presence of Astroblepus mariae.eng
dc.description.abstractLas especies del género Astroblepus habitan en la cordillera de los Andes en Suramérica. Desde tiempos remotos sus hábitats han sufrido transformaciones rápidas que han resultado en niveles inimaginables de degradación. Sin embargo, es escaso el conocimiento sobre las perturbaciones de hábitat y la desaparición simultánea de especiesendémicas del género Astroblepus . En general, los suelos de la cordillera de los Andes se caracterizan por su fertilidad, por lo que extensas regiones han sido transformadas para la agricultura y el pastoreo de ganado, procesos que requieren del uso de agua proveniente de arroyos y manantiales, lo cual conlleva cambios notables en la configuración natural de estos sistemas de agua, así como la desaparición de peces, zooplancton y flora acuática.A pesar de estas acciones antrópicas, algunas especies de Astroblepusparecen tener la capacidad de responderrápidamente a las transformaciones del hábitat y de sobrevivir en estas condiciones Se discute aquí la incidencia de la perturbación del hábitat en un tramo de arroyo con presencia de Astroblepus
