Abstract (en):
The bullfrog is one of the most aggressive invasive species globally because of their wide dispersal ability, competence and their voracious eating habits. In Colombia, the species has been reported since the early 80's when entered the country as an economic alternative in the frog breeding and distribution has increased since then. This work has modeled potential distribution of the species in Colombia based upon the projection of the distribution in the native area in the northeastern United States. Likewise, the distribution was compared with the current potential future distribution of three global circulation models (CCCMA-CGCM31, CSIRO_MK30 and IPSL_CM4) and over two time horizons (2050 and 2080 yrs). It was determined that the Andes and the Caribbean Region in Colombia presents optimal areas for the establishment of the species present and the future. It is urgent to design and implement a management and control plan for Bullfrog populations in Colombia, to identify invaded areas and perform control of this species. This article provides some basis for the development of this plan in Colombia.
Abstract (es):
La rana toro es una de las especies invasoras más agresivas a nivel global debido a su amplia capacidad de dispersión, de competencia y por sus hábitos alimenticios voraces y plásticos. En Colombia la especie ha sido reportada desde la década de los 80's cuando fue introducida al paÃs como alternativa económica en la ranicultura y su distribución se ha incrementado desde ese entonces. En el presente trabajo se realizó un modelo de distribución potencial de la especie para Colombia basado en la proyección de la distribución actual en el área nativa, en el noreste de los Estados Unidos. Asà mismo se comparó la distribución potencial actual con la distribución
futura en tres modelos globales de circulación (CCCMA-CGCM31, CSIRO_MK30 y IPSL_CM4) y a lo largo de dos horizontes de tiempo (años 2050 y 2080). Se determinó que los Andes y la región Caribe en Colombia presentan áreas óptimas para el establecimiento de la especie en el presente y en el futuro. Es urgente realizar un plan de manejo y control de la rana toro en Colombia, identificar las áreas invadidas para controlar las poblaciones de esta especie y tomar medidas preventivas en áreas potenciales para la invasión.
