The Colombian slider turtle (Trachemys callirostris callirostris) is a subspecies under a high level of exploitation in Colombia, of which nothing is known about its reproduction in highly disturbed areas with low hunting pressure. We studied some reproductive traits in three different aquatic environments created by coal mining in the Cerrejon mine, La Guajira department, during part of the reproductive season in 2011 (between March and June). We recorded hatching success (56.9 %) only in the stabilization ponds. In the mining reservoir, the 100% predation rate was the factor limiting hatching success. The recommended option there is protect the nests from the main predator (Procyon cancrivorus) and the relocation of some of them for ex-situ incubation. The low level of nesting recorded in the rehabilitated area may have been the result of extraction of adult females, but also could be due to habitat limiting factors influencing the growth of individuals, or by demographic factors. Size variables measured for clutches, eggs, and hatchlings at the three study sites, showed the possibility that nesting females are larger than those of other populations subjected to hunting in Colombia. However, to determine the extent of geographic variation when compared to other populations it will be necessary to examine temporal variation in reproductive traits of the Cerrejon population. REPRODUCCION DE Trachemys callirostris callirostris (EMYDIDAE) EN AMBIENTES GENERADOS POR LA MINERIA EN LA GUAJIRA, COLOMBIA La tortuga hicotea (Trachemys callirostris callirostris) es una subespecie sometida a una alta extraccion en Colombia, de la cual no se conoce nada sobre su reproduccion en zonas altamente alteradas con bajo impacto por la caceria. Para ello, en tres ambientes acuaticos generados por la mineria de carbon en la mina del Cerrejon, departamento de La Guajira, estudiamos algunas caracteristicas reproductivas de la hicotea durante el periodo reproductivo de 2011 (marzo a junio). Solamente en las lagunas de estabilizacion registramos un exito de eclosion positivo (56,9 %). En el embalse de mineria, la tasa de depredacion de 100 % fue el factor limitante del exito de eclosion, por lo que recomendamos el aislamiento de los nidos del principal depredador (zorro paton: Procyon cancrivorus) y el traslado de nidadas para su incubacion ex-situ. La baja anidacion registrada en la zona rehabilitada pudo haberse debido a una extraccion de hembras adultas, a factores limitantes del habitat que influyen en el crecimiento de los individuos, o por factores de tipo demografico. Las diferentes variables estudiadas a nivel de los huevos y los neonatos en los tres sectores, evidencian la posibilidad de que las hembras anidantes posean tamanos mayores que las de otras poblaciones de Colombia sometidas a la caceria. Sin embargo, para establecer el grado de variacion geografica, es necesario determinar la variacion temporal de las caracteristicas reproductivas en la poblacion del Cerrejon.
