| description |
The objective of this study was to identify and describe the nesting habitat of Podocnemis sextuberculata at Erepecu Lake, Trombetas River Biological Reserve, (REBIO-Trombetas; Pará-Brazil). Initially, the main features of the beaches that potentially determine the habitat selection by cupiso for nesting were described. The nests observed on the beaches were recorded, marked and fenced as protection from natural predators. Information regarding date and location was analyzed through simple linear regression for each nest in order to determine relationships between beach features and number of nests. The results showed a positive co-relationship between number of nests and area. Nest site selection by P. sextuberculata in the beaches of the Erepecu Lake could depend on trade-off scenarios among natural threats and a suitable nesting habitat. We also suggest that, due to the high annual hydrologic oscillations, it is possible that the driving factor for habitat selection would be the risks that the females are exposed to while searching for a nesting site, rather than a particular habitat type. |

Inicialmente se describieron las principales características de las playas escogidas, los nidos encontrados fueron marcados y cercados para su protección contra la depredación natural. A través de regresiones lineales simples se determinó que el número de nidos por playa se correlacionó significativamente con el “área” de las playas. Los resultados muestran que la selección del lugar de nidificación en las playas del lago Erepecu por P. sextuberculata, podría depender en unos escenarios de compensación entre las amenazas naturales y un hábitat adecuado para anidar. Debido a la gran fluctuación hidrológica anual, es posible que el factor determinante para selección de las hembras sea el riesgo de exposición de las hembras durante la búsqueda de área de anidación, más que el tipo de hábitat en particular.application/pdfspaUniversidad Nacional de Colombia - Sede Bogotá - Faculdad de Ciencias - Departamento de Biologíahttps://revistas.unal.edu.co/index.php/actabiol/article/view/42757Universidad Nacional de Colombia Revistas electrónicas UN Acta Biológica ColombianaActa Biológica ColombianaBermúdez Romero, Ana Lucia and Castelblanco-Martínez, Nataly and Bernhard, Rafael and Duque, Santiago R. and Vogt, Richard (2015) Nesting habitat of the ‘cupiso’ podocnemis sextuberculata (Testudines: Podocnemididae) in erepecu lake (Pará-Brazil).
