Abstract

Seasonal changes of proportional distribution, bioticindices, abundance, and frequency of benthic macroinver-tebrate communities in Menderes Creek were investigatedat 5 stations between November 2005 and July 2006. Thefauna included a total of 87 taxa belonging principally toInsecta (52 taxa, especially Chironomidae), Oligochaeta(12 taxa), Mollusca (11 taxa), Hirudinae (7 taxa), and Ma-lacostraca (5 taxa). Mean density was estimated to be 778individuals m–2 for the 87 taxa. Mollusca (38.5%) and In-secta (39.9%) are the dominant groups among the macroin-vertebrate assemblages. Average Shannon-Wiener diversityindex was calculated as 1.41, average Margalef's richnessindex was 1.27, and average Pielou index was 0.61. Theresults of one-way analysis of similarity (ANOSIM) in-dicated that macroinvertebrate compositions were signifi-cantly different between sampling sites (p< 0.05). ANOSIMand similarity percentage analysis (SIMPER) revealed sig-nificant differences and a high degree of community dis-similarity within and between the sampling stations.
