渔山列岛夏季潮间带大型底栖生物群落结构研究
Study on the macrobenthic community structure in the intertidal zone of the Yushan Islands in summer
摘要
Abstract
Based on the samples of macrobenthos collected from four sections of the rocky intertidal zone of the Yushan Islands, the composition, distribution, diversity, and community structure of the species were studied in August 2014. A total of 98 species (70 macrozoobenthos and 28 macroalgae) were identified from the total sample size studied, of which the following 9 species were dominant: Echinolittorina radiata (Souleyet), Septifer virgatus (Wiegmann), Mytilus coruscus (Gould), Modiolus comptus (Sowerby), Lasaea nipponica (Keen), Tetraclita japon-ica (Pilsbry), Megagbalanus volcano (Pilsbry), Corallina officinalis (Linnaeus), and Gelidium divaricatum (Marteus). The average biomass and abundance in all the sections were found to be 8515.50 g·m?2 and 6841.63 ind·m?2, re-spectively. Other calculated parameters were as follows: Shannon-Wiener index (H′) = 1.89 ± 0.14, Margalef index (d) = 3.66 ± 0.52, and Pielou index (J ) = 0.38 ± 0.01. The Abundance Biomass Curve showed that the commu-nity structure of macrobenthos was evenly disturbed in the four sections. Compared with the findings of past studies, the number of species reduced significantly while the biomass and abundance increased, and dominant species were gradually succeeded by other small-size species such as T. japonica and S. virgatus. This investigation provides im-portant references for the management and sustainable use of intertidal biological resources in the Yushan Islands.关键词
