主 题：vertical distribution biodiversity taxonomic diversity index trophic structure
摘 要：We investigated the diversity and structure of free-living marine nematode communities at three sandy beaches representing typical intertidal environments of a temperate zone in Qingdao,Shandong Province,*** nematode abundance ranged from 1006 to 2170 ind.10 cm-2,and a total of 34 nematode genera were recorded,of which only 8 were common in all the studied *** s evenness and Shannon-Wiener diversity index were the lowest at the second beach where nematode abundance was the *** highest species diversity index coincided with the lowest nematode abundance at Shilaoren *** median grain size,sorting coefficient,and chlorophyll-a content were essential for differentiation in nematode abundance and species diversity,whereas taxonomic diversity of nematode was homogeneous across the three *** 0–20 cm sediment profile,nematode abundance declined abruptly with depth,whereas nematode diversity changed gently with obvious difference in 16–20 cm *** granulometry and chlorophyll-a content were the two foremost factors which influenced the vertical distribution pattern of nematode generic ***-selective deposit feeders constituted the most dominant trophic group,followed by epistratum ***(family:Tripyloididae) dominated at the second and Yangkou beach,while Theristus(family:Xyalidae) prevailed at Shilaoren *** and predators became important at Shilaoren beach because of the high proportion of *** though,nematode community of the studied beaches did not differ significantly from each other.
