Meiobenthic assemblages in some intertidal areas around Qatar, Arabian gulf

Abstract

Sediment core samples were collected in 10 locations around intertidal areas of Qatar to acquire baseline information on meiobenthic density and composition. Temperature, salinity, and pH of interstitial waters were measured, in situ. Additional core samples were collected for nutrient and granulometry analysis. A total of 74 taxonomic groups belonging to 14 phyla were recorded. Total mean density was 120.89 ind/10cm2 , with a range 0.42 to 16.73 ind/10cm2 . High densities were recorded in Al Wakra 1 (rocky shore), Simaisma, Al Khor and Al Zubara. Furthermore, Al Zubara showed high species richness, expH’ and evenness index. High nematode/copepod ratios were recorded in Fuwairit and Al Wakra 2 (mangrove area). Meiofaunal densities and composition were associated with sediment characteristics and total organic matter availability in the area. Further investigations should be done on meiofaunal community of Qatar to determine the effect of seasons and other anthropogenic activities on the community
