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.

Parental effects have been shown to buffer the negative effects of within-generation exposure to ocean acidification (OA) conditions on the offspring of shallow water marine organisms. However, it remains unknown if parental effects will be impacted by the presence of diel CO 2 cycles that are prevalent in many shallow water marine habitats. Here, we examined the effects that parental exposure to stable elevated (1000 µatm) and diel-cycling elevated (1000 ± 300 µatm) CO 2 had on the survival and growth of juvenile coral reef anemonefish, Amphiprion melanopus . Juvenile survival was unaffected by within-generation exposure to either elevated CO 2 treatment but was significantly increased (8%) by parental exposure to diel-cycling elevated CO 2 . Within-generation exposure to stable elevated CO 2 caused a significant reduction in juvenile growth (10.7–18.5%); however, there was no effect of elevated CO 2 on growth when diel CO 2 cycles were present. Parental exposure to stable elevated CO 2 also ameliorated the negative effects of elevated CO 2 on juvenile growth, and parental exposure to diel CO 2 cycles did not alter the effects of diel CO 2 cycles on juveniles. Our results demonstrate that within-generation exposure to diel-cycling elevated CO 2 and parental exposure to stable elevated CO 2 had similar outcomes on juvenile condition. This study illustrates the importance of considering natural CO 2 cycles when predicting the long-term impacts of OA on marine ecosystems.
