First Time

Present study was performed for taxonomic identification, assemblage, richness, spatial distribution and abundance analysis of chironomid larvae in the benthic and lentic shoreline habitat of Rajsamand Lake, India. Chironomids play an important role in shallow water aquatic ecosystems, so this study will give an idea about ecology of this area. Topographical and environmental factors are strongly correlated with the composition of chironomid communities. No information is available regarding these organisms in this defined area, so this study would provide data for comparison with chironomid community present in nearby and other ar ea, where study on chironomids is already done or will be done. This study on chironomids was conducted for the first time in Rajsamand Lake, India. Specimens were collected at seven sampling sites along shoreline of the Lake. A total of four genera (viz. Chironomus, Cryptochironomus, Einfeldia and Polypedilum) were reported. Polypedilum was the most dominant genus reported followed by Chironomus, Einfeldia and Cryptochironomus. Genus Cryptochironomus was reported for the first time in Rajasthan.

Interpretation of wireline logging data supported to recover the sedimentary environment of block 102 of Song Hong basin. It inchided in determination of the spatial distribution of source, reservoir and cap rocks and an indispensable part in oil exploration of this area. Resulted wireline logging data showed some sedimentary environment units as the following The late Oligocene was delta environment. It was identified as forming delta plain, swamp to lacustrine. The middle Miocene had changed to shallow water marine environment, which formed the shoreface, tidal flat, lagoon and channel. The lower Miocene was aluvial environment that changed into fluvial and coastal plain.

The Relationship

The abundance, biomass, and composition of the dominant phytoplankton species in the shallow-water high-trophic lake Nero in June and August 2017 were analyzed. The analysis of its spatial distribution over the water area of the lake, comparison of the data obtained with the results of the previous study period up to 2012–2013, and a statistical analysis of the relationship between phytoplankton abundance and biomass and hydrophysical and some hydrochemical parameters were carried out. The multifactorial limitation of phytoplankton development in summer was established.

Species Composition And Structure

The deepwater mud-bottom community identified previously as one of three benthic infauna communities off the coast of Washington was found at mean depths of 154.5 m in sediments with a mean mud percentage of 50.09%. The most abundant species were the polychaetes Prionospio malmgreni, Sternaspis fossor, and Ninoë gemmea, the lamellibranchs Axinopsida serricata, Adontorhina cyclia, and Macoma carlottensis, and the amphipod Heterophoxus oculatus. The mean standing crop (ash-free dry weight) was 3.058 g/m2, with the echinoderms Brisaster latifrons, Ophiura lütkeni, and Amphioplus sp. and the polychaete Sternaspis fossor as the major contributors to the standing crop.The intermediate depth sand-bottom community was found at stations with a mean depth of 95.8 m in sediments with a mean sand percentage of 67.81%. The most abundant species were the polychaetes Magelona sp., Sternaspis fossor, Nephthys sp., and Haploscoloplos elongatus, the lamellibranchs Yoldia ensifera and Axinopsida serricata, and the amphipod Paraphoxus variatus. The mean standing crop was 2.533 g/m2, with the species listed above and the lamellibranch Macoma elimata as the major contributors to the standing crop.The shallow water sand-bottom community was found at stations with a mean depth of 36.0 m in sediments with a mean sand percentage of 96.33%. The most abundant species were the cumacean Diastylopsis dawsoni, the amphipods Ampelisca macrocephala and Paraphoxus obtusidens, the lamellibranchs Tellina salmonea and Macoma expansa, and the polychaete Owenia fusiformis. The mean standing crop was 1.398 g/m2, with the species listed above and the polychaetes Nephthys sp. and Chaetozone setosa and the lamellibranch Siliqua patula as the major contributors to the standing crop.There was a distinctly lower species diversity in the shallow water sand-bottom community than in the two communities in deeper waters.
