Abstract (en):
The present study evaluates occupation of Caiman crocodilus fuscus (babilla) at artificial lagoons (jagüeyes)
constructed as a watering place for cattle. These water bodies are located on the coastal anthropic savannah
landscape matrix in the Colombian Caribbean, in the Sucre department, belonging to the tropical dry forest
with high environmental deterioration. Population of babillas in three jagüeyes without connection between
them, were analyzed through successives captures, both in dry and rainy seasons. The statistical results shown
significant differences (p<0,05) among the babilla population due to the lagoon dimensions. The occupation for gender and sexual maturity also shown significant differences (p<0,05), as well as the density along year seasons. The âjagüeyesâ are recognized as a refuge for this subspecies in the study area, and they can support moderate balance populations, becoming valuables conservation units for the region. It states that there is site fidelity, manifested mainly in females, and that this is related to the supply of habitat and reproductive factors.
Abstract (es):
Se evalúa la ocupación que hace Caiman crocodilus fuscus (babilla) de jagüeyes o lagos artificiales, construidos como abrevaderos de ganado vacuno, ubicados dentro de una matriz paisajística de sabana antrópica costera del Caribe colombiano. Esta se ubica en el departamento de Sucre, perteneciente al bosque seco tropical con alto deterioro ambiental. Se analizaron mediante capturas sucesivas, tanto en época de sequía como en época de lluvias, tres jagüeyes que no tenían conectividad entre ellos. Los resultados analizados estadísticamente muestran que existe diferencia significativa (p<0,05) en el tamaño de los jagüeyes, igualmente se tienen diferencias significativas (p<0,05) al analizar la ocupación por sexo y estado de madurez, así como la densidad por época del año. Se reconoce a los jagüeyes como refugio de esta subespecie para la zona de estudio, que pueden mantener moderadas poblaciones equilibradas, convirtiéndose en valiosas unidades de conservación para la región. Se establece que existe fidelidad de sitio, que se manifiesta principalmente en las hembras y que se le relaciona con
oferta de hábitat y con factores reproductivos.
