主 题:Dam construction Extinction Habitat recovery Recolonisation Turnover
摘 要:Background:Habitat degradation is known to have a major impact on the composition of bird communities,yet how these communities recover following such disturbance is less *** study examined bird community changes from pre-logging to recovery over the course of habitat disturbance caused by the development of the Hulu Terengganu Hydroelectric Dam Project in Peninsular Malaysia,between 2007 and *** surveys were conducted using point count observations and mist netting in the dam area from the prelogging phase until the operation ***:It was observed that while bird species significantly declined after large-scale habitat clearance between the pre-logging and construction phases,they showed positive signs of recovery from the inundation to operation *** findings indicate that the bird community is still recovering,and the permanent loss of habitat required by most of the original species has not occurred,as evidenced by *** species composition differed across phases due to varying habitat *** turnover rate and immigration rate(recolonisation and newly recorded species)were higher between the construction and operation *** was also observed that insectivorous birds were more heavily affected than others by changes to the landscape,which highlights the versatility,survivability and tolerance of certain species to extreme disturbance and habitat ***:Although the operation phase showed an incremental change in bird species richness due to recolonisation and newly recorded species,this value remains far from that of the pre-logging *** predict that bird species recovery will continue to increase for some time before reaching a plateau among the newly created islands,reservoir and catchment area of the dam.
