Forest structure of artificial islands in the Tucuruí dam reservoir in northern Brazil: a test core-area model Acta Amazonica
Ferreira,Leandro V.; Neckel-Oliveira,Selvino; Galatti,Ulisses; Fáveri,Sarita B.; Parolin,Pia.
Construction of hydroelectric dams in tropical regions has been contributing significantly to forest fragmentation. Alterations at edges of forest fragments impact plant communities that suffer increases in tree damage and dead, and decreases in seedling recruitment. This study aimed to test the core-area model in a fragmented landscape caused by construction of a hydroelectric power plant in the Brazilian Amazon. We studied variations in forest structure between the margin and interiors of 17 islands of 8-100 hectares in the Tucuruí dam reservoir, in two plots (30 and >100m from the margin) per island. Mean tree density, basal area, seedling density and forest cover did not significantly differ between marginal and interior island plots. Also, no...
