| Abstract |
The spatial distribution of meiofauna and their relationship with environmental factors were investigated in four stations with different sediment types (coarse silt, fine, medium and coarse sand) in the southern Caspian Sea in November 2013. In total twenty nine species were identified and nematodes with fifteen species was the dominant group in term of density and species number. The maximum meiofauna densities were observed in fine and coarse sand stations while the minimum density was observed in coarse silt station. The highest species number and Shannon diversity were obtained in medium sand station while coarse silt station showed the lowest values. Results of Permanova analysis revealed two main different meiofauna communities in the sampling stations while the genus Daptonema was the most dominant meiofauna group in all stations. Total meiofauna density, species number, Shannon and evenness showed a significant relationship with sediment grain size and total organic matter content. |
