EDGE EFFECT FROM CONTINUOUS FOREST AND FRAGMENT FOREST ON THE LARVAL PERFORMANCE OF AN AQUATIC ANURAN TADPOLE AND PREDATOR-PREY INTERACTION IN CENTRAL AMAZONIAN

Resumo


Efeito de borda de floresta contínua e fragmento de floresta sobre a performance larval de um girino anuro e interação predador-presa na Amazônia Central

 

Nós examinamos como a interação predador-presa de uma larva de anuro é influenciada pela proximidade da borda de floresta contínua e de fragmentos de floresta tropical primária de terra-firme. Os resultados mostraram que a proximidade da borda de floresta contínua e de fragmentos florestais não afetou a sobrevivência e o desenvolvimento de Osteocephalus taurinus com e sem predadores, indicando que nem as mudanças no hábitat nem os predadores causaram o padrão observado na performance larval. Em uma análise gráfica, ambos parâmetros apresentaram números suavemente mais altos em floresta contínua.

ABSTRACT

 

We examine how the predator-prey interaction of aquatic anuran larva is influenced by proximity of edge from continuous forest and fragments of primary tropical terra-firme forest. Results showed that the proximity of edge of these habitats did not affect survival and larval development of Osteocephalus taurinus with and without predators, indicating that neither the habitat changes nor the predators caused the observed pattern in larval fitness. In a graphic analysis both parameters showed lightly higher numbers in continuous forest.
