description |
The purpuse of this study was to investigated the influence of anthropogenic impacts on Podocnemis unifilis nesting on a stretch from Falsino river, with two forest reserves, and one urban area on the Araguari river, state of Amapá, eastern Amazon (Brazil). A total of 180 nests were found, being 89.4 % in the forest reserves and only 10.6 % in urban areas. On Falsino river, we observed a spawning pattern, because the number of nests was correlated to the length and width of the nesting locations. On Araguari river, the P. unifilis nests were generally found in areas with surrounding vegetation up to 5 meters in height, minimum distance of 120 meters from residences and immediately or after places of higher exploration of pebbles. Females from Falsino river had smaller eggs, but the neonates were bigger and with higher body condition index than the neonates from Araguari river. About 80 % of the nests were prey, mostly because of the large collection of eggs for feeding. Furthermore, it was found that adult turtle hunting has been intense. Although one of the areas is in forest reserves, the human impacts were similar to those caused in urban areas, indicating the need to implement protection programs for the conservation of P. unifilis. |

Un total de 180 nidos fueron localizados y 89,4 % estaban en las áreas de reservas forestales, pero sólo el 10,6 % en las zonas urbanas. En el río Falsino, hubo desove patrón, el número de nidos se correlacionó con la longitud y la anchura de los sitios de anidación. En Río Araguari, nidos de P. unifilis se encuentran generalmente en lugares con vegetación circundante de hasta 5 metros de altura, distancia mínima de 120 metros de residencial y de inmediato o después de los lugares de mayor explotación de los guijarros. En el río Falsino, aunque las hembras han demostrado huevos más pequeños, los recién nacidos fueron mayores y la puntuación cuerpo también es mayor que en los recién nacidos del río Araguari. En la región del Río Araguari, aproximadamente el 80 % de los nidos fueron depredados, debido a la gran colección de huevos para la alimentación. Se observó que la presión de caza en las tortugas adultas ha sido intensa. Aunque es una de las áreas a ser bosques protegidos, los impactos humanos fueron similares a los de las zonas urbanas, lo que indica la necesidad de implementar programas de protección para la conservación de P. unifilis.We investigated the influence of anthropogenic impacts on Podocnemis unifilis nesting on a stretch from Falsino river, with two forest reserves, and one urban area on the Araguari river, state of Amapá, eastern Amazon (Brazil).
