Abstract (en):
During the last 30 years published books and red lists have been used to draw attention about threatened species at the global, regional and national levels. From the 1980âs Colombia has elaborated books and red lists of species including two assessments for freshwater fish in 2002 and 2012. The first assessment proposed a series of conservation measurements to increase knowledge and to improve speciesâ conditions. Of the 45 species listed in 2002, 23 remain the same category of threat or evaluation, three species increase in the threat category and 19 species decrease their category. Here we analyze the impact and development of those proposals and the evolution of the conservation status of freshwater fish in Colombia. We evaluate the change of threatened species categories and calculate the Red List Index (RLI) for the group.
Abstract (es):
Las publicaciones de libros y listas rojas han sido utilizadas durante los últimos 30 años para llamar la atención sobre las especies que se encuentran amenazadas de extinción en el ámbito mundial, regional o nacional. Colombia ha elaborado listas y libros rojos desde la década de los 80 y el grupo de peces dulceacuícolas cuenta actualmente con dos evaluaciones (2002 y 2012). En la primera evaluación se propusieron una serie de medidas de conservación en pro de aumentar el conocimiento sobre las especies y en busca de mejorar sus condiciones. De las 45 especies listadas en el 2002, 23 mantienen la misma categoría de amenaza o evaluación, tres especies aumentan en su categoría de amenaza y 19 especies disminuyen su categoría. En este artículo se analiza el impacto y desarrollo de dichas propuestas, la evolución del estado de conservación de las especies de peces dulceacuícolas del país, el cambio en las categorías de amenaza y se calcula el índice de las listas rojas (RLI).
