ABSTRACT

Translocation experiments showed that a woodcreeper bird species is able to move between isolated forest fragments, but this ability is limited by increasing interpatch distances. Larger distances (> 100 m) were overcome by using small stepping-stones (isolated trees), which enhance connectivity and are useful for the species conservation in fragmented landscapes.

RESUMO

Experimentos de translocação demonstraram que uma espécie de arapaçu é capaz de mover-se entre fragmentos florestais, mas essa habilidade é limitada por seu isolamento. Distâncias maiores que 100 m foram vencidas com o uso de árvores isoladas, as quais aumentam a conectividade e são úteis para a conservação dessa espécie em paisagens fragmentadas.
