Iranian Biology Society Journal of Animal Research (Iranian Journal of Biology) 2383-2614 29 1 2016 05 21 Study of biodiversity and identification of foraminifera communities In the eastern Qeshm island Study of biodiversity and identification of foraminifera communities In the eastern Qeshm island 1 17 723 FA Journal Article 2015 03 18 This investigation carried out to study of foraminifers’ communities in the eastern part of Qeshm Island during the hot and the cold seasons. Samples were collected with 3.3 cm diameter corer from the first 5 cm surface of sediments in 9 stations with 3 replicates. In the study 44 specimens were identified specifically, and 31 specimens were typificated at genera; they included 25 families. Organisms were rillustrated using Scaning electron microscop photography. Maximum abundance of live individuals was related to Ammonia beccarii (22.7 ind/10cm2) and Protoelphidium sp. (13.9 ind/10cm2) in winter 2014. In the summer 20143 Triloculina oblonga (147.9 ind/10cm2) and Protoelphidium sp. (81.19 ind/10cm2) were observed at higher abundance. The Shannon –weaner index from minimum 0.3 in winter to maximum 4.4 in summer was ranged. Significant correlation between some environmental factors and foraminifer abundances was found (P<0.05) using spearman correlation test. A correlation was found between total abundance of foraminifers and silt - clay portions of sediments, salinity and pH in summer never in winter. The abundance of Protoelphidium sp. and Elphidium vitreum showed correlation with the dissolved oxygen and the silt-clay portion.
