“…We collated a 100-lake dataset of light, temperature, and Chl fluorescence profiles collected during the summer stratified period from the Global Lake Ecological Observatory Network (GLEON; Weathers et al 2013;Rose et al 2016) to assess the relative importance of variables associated with light availability vs. those associated with the depth and strength of thermal stratification to predict DCM depth and thickness. Additionally, we assessed how light-and stratification-associated variables scaled across broad gradients of lake morphometry and transparency.…”

The vertical distribution of chlorophyll in stratified lakes and reservoirs frequently exhibits a maximum peak deep in the water column, referred to as the deep chlorophyll maximum (DCM). DCMs are ecologically important hot spots of primary production and nutrient cycling, and their location can determine vertical habitat gradients for primary consumers. Consequently, the drivers of DCM structure regulate many characteristics of aquatic food webs and biogeochemistry. Previous studies have identified light and thermal stratification as important drivers of summer DCM depth, but their relative importance across a broad range of lakes is not well resolved. We analyzed profiles of chlorophyll fluorescence, temperature, and light during summer stratification from 100 lakes in the Global Lake Ecological Observatory Network (GLEON) and quantified two characteristics of DCM structure: depth and thickness. While DCMs do form in oligotrophic lakes, we found that they can also form in eutrophic to dystrophic lakes. Using a random forest algorithm, we assessed the relative importance of variables associated with light attenuation vs. thermal stratification for predicting DCM structure in lakes that spanned broad gradients of morphometry and transparency. Our analyses revealed that light attenuation was a more important predictor of DCM depth than thermal stratification and that DCMs deepen with increasing lake clarity. DCM thickness was best predicted by lake size with larger lakes having thicker DCMs. Additionally, our analysis demonstrates that the relative importance of light and thermal stratification on DCM structure is not uniform across a diversity of lake types.

“…The family Daphnidae, which was determined to contain the majority of the species among the recognised cladocerans, includes Ceriodaphnia cornuta and Diaphanasoma sarsi, Cladocera was the most prevalent zooplankton group in the study. According to [8,9], cladoceran not only serve as a vital food source for planktivorous fish and aquatic invertebrates, but they also graze on algae and other debris and can be involved in the recycling of nutrients in aquatic ecosystems.…”

“…The head is large, the carapace is oblong-oval in shape, the ventral parts form a narrow free flap with feathered margins, the antennae do not reach the posterior margin of the valves, the head is truncate anteriorly, and the frontal portion of the head contains numerous crystalline lenses [3,[11][12][13][14][15][16][17][18][19][20]. The claw has three basal spines, and the post abdomen is narrow and covered with fine setules [21][22][23][24][25][26].…”

Cladocerans are a ubiquitously prominent component of zooplankton and limnological systems. In aquatic ecosystems, cladocerans play a significant role in the food chain and secondary production. 620 species of cladocerans have been reported worldwide to far, making them a very old group with Palaeozoic origins. There are currently over 130 species known to exist in India, with Northeastern India having the greatest taxonomic status. A wide variety of small crustaceans known as Cladocera are found in a variety of aquatic settings, from shallow temporary ponds to deep lakes and wide rivers. Cladocerans are a vital source of food for crustaceans, tiny fish, and aquatic insects. Three treated sewage water fed ponds at CHRIST (Deemed to be University), Bengaluru, Karnataka's Main Campus (MCP: 12.555°N, 77.361° E), Bannerghatta Campus (BCP: 12.523°N, 77.354° E), and Kengeri Campus (KCP: 12.514° N, 77.261° E), have been undertaken to study the composition of and occurrence of Cladocera species. In the above study there were 3 species caldoceras observed from all the three study sites of treated sewage water.
