Scale- and trait dependent responses of bird communties to lowland rainforest restoration and frugivore-bird-seed interaction networks in Sumatra, Indonesia

摘要: Recovery of tropical secondary forest will require human assistance. The first important part in restoration is understanding the existing biodiversity and ecosystem service within use this to decide appropriate treatment measure progress towards success. This knowledge still limited for many Southeast Asia. research aimed provide knowledge, specifically we looked at bird community structure, birds seed dispersal, densities Harapan Rainforest Concession, Jambi Province, Sumatra, Indonesia, between 2011-2012. Our results showed habitat-scale variables that correlate with different functional groups hence can be used identified assist have been found decline after logging. We provided density information 45% lowland specialist Sumatra (i.e. species occur below 200 meter altitude). baseline could assess restoration, particularly lower degraded (young forest) compared less (old forest). At network level, frugivore bird-seed interaction networks young old were relatively similar dominated by generalist birds. A change importance two types observed, i.e. one type was not another type, perhaps due differences higher most bird). In short, structure rainforest affected characteristics spatial scales, which influenced also dispersal thereby, their contribution regeneration. detailed on patterns as a basis improved management practices.
