Ecological characteristics of macrobenthos found in the inter-tidal zone of Ningjin, Shandong
摘要
Abstract
The ecological characteristics and seasonal variation of the macrobenthic community in the intertidal zone of Ningjin Town, Shandong Peninsula were investigated on the basis of the samples collected from the surveys conducted in November 2009 and February, May, and August 2010 (representing autumn, winter, spring, and sum-mer, respectively). Intotal, 45 macrobenthic species were identified, of which, 20 were Crustaceans, 14 were Mol-luscs, 9 were Polychaetes, and the remaining 2 belonged toother benthic taxa. The dominant species varied during the four seasons, with the exceptionof Gammaridea, whichwas predominantall year round. The average biomass from the four surveys was 45.09 g/m2 with the highest biomass found during autumn and the lowest during spring. The spatial distribution of biomass demonstratedthe tendency as medium tidal zone > low tidal zone > high tidal zone except during spring. The average abundance was 182.67 ind/m2 with the highest abundance found during summer and the lowest during winter. The annual mean Shannon index (H′) of the macrobenthos community in the region studied was 1.09; its seasonal variation was winter > autumn > summer > spring, and the spatial variation was low tidal zone > medium tidal zone > high tidal zone. Compared with previous reports of the adjacent areas, all the biological parameters of macrobenthos from the intertidal zone of Ningjin were relatively low.关键词
