RESUMENEl objetivo de esta investigación fue conocer aspectos poblacionales, biológicos y ecológicos de las tortugas carey (Eretmochelys imbricata) presentes en el Pacífico sur de Colombia (Departamento del Cauca), para esto se tomó información de morfometría, se revisó el estado de salud de los individuos y se tomaron muestras de sangre para valoración de química sanguínea. Durante siete meses de muestreo se capturaron 25 tortugas carey (16 individuos diferentes) en los arrecifes del Parque Nacional Natural Gorgona, con un porcentaje de recaptura del 46 %. Aunque no se notaron problemas evidentes de salud, la mayoría de animales presentaron gran parte del caparazón cubierto de algas filamentosas y algunos epibiontes sobre el plastrón y el caparazón. La Longitud Curva Caparazón (LCC) mostró una mayor proporción de individuos con tallas entre 37 y 45 cm de longitud (prom. 42,3 cm; min. 37,5 cm; max. 58 cm). Por medio de la prueba de Mann Whitney U, se comparó la LCC de los 16 individuos diferentes capturados en el PNN Gorgona, con 11 individuos capturados en la zona del litoral del Departamento del Cauca, encontrándose diferencias significativas entre estos dos grupos, donde los animales presentes en el PNN Gorgona fueron de mayor talla que los presentes en el continente (Z = -2,59; p = 0,007). Los valores de ácido úrico se encontraron por encima de los valores de referencia.Palabras clave: bioquímica sanguínea, longitud curvo caparazón, Parque Nacional Natural Gorgona. ABSTRACTThe objective of this research was to determine biological and ecological population characteristics of the hawksbill turtle (Eretmochelys imbricata) found in the southern Colombian Pacific department of Cauca. Morphometric measurements were recorded, the health status of individuals was reviewed, and blood samples were taken for a biochemistry assessment. During the seven months of the investigation, 25 hawksbill turtles were caught (16 different individuals) on the reefs of Gorgona Natural National Park. Forty-six percent of the total numbers of turtles assessed were recaptured during the study period. While no obvious health problems were noted, most animals possessed epibionts and filamentous algae covering the carapace, some parts of the limbs, as well as on their neck. Curved carapace length (CCL) showed the highest proportion of individuals were between 37 and 45 cm.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
