Zooplankton Diversity and their Monthly Variation Reflecting Cultural Eutrophication of Chakki Talab, Bodhan, Telangana, India | Chapter 11 | Contemporary Research and Perspectives in Biological Science Vol. 3

 

The present work aimed to determine the monthly variations of zooplankton, the potent biological indicators to know the ecological status of Chakki Talab, Bodhan, India. Multiple studies have made a consistent and crucial realization that zooplankton taxa are rapid responders to many environmental stressors, such as hydrological changes, climate changes and anthropogenic activity-induced water pollution. Chakki Talab, located in Bodhan, Telangana, India, is one of the urban lakes in the country facing challenges from excessive nutrient input, which contributes to cultural eutrophication and subsequently degrades water quality. In freshwater bodies, zooplankton play an important role in maintaining the ecological balance and are used as potential bioindicators for assessing water quality, biological monitoring and changing trophic conditions. In the study conducted over a year, from October 2015 to September 2016, the zooplankton diversity of Chakki Talab was assessed on a monthly basis. The relative abundance of zooplankton was observed to be highest with Rotifera (31%), followed by Ostracoda (27%), Protozoa (21%), Copepoda (11%), Chironomidae (9%), and Cladocera (1%). The predominance of Rotifera, throughout the investigation indicates a significant influx of nutrients into Chakki Talab from nonpoint sources. To mitigate the impact of nutrient overloading and to preserve the ecological status of Chakki Talab, it is advisable to implement ongoing monitoring and management strategies. Continuous surveillance is crucial to track changes in water quality and to ensure the sustainability of this freshwater ecosystem.

Assessing the Composition of Particulate Organic Matter and Zooplankton Food Sources in Lake Superior and Across a Size-Gradient of Aquatic Systems | Chapter 1 | Contemporary Research and Perspectives in Biological Science Vol. 5

Food webs in aquatic systems can be supported both by carbon from recent local primary productivity and by carbon subsidies, such as material from terrestrial ecosystems or past in situ primary productivity. The importance of these subsidies to respiration and biomass production remains a topic of debate.  While some studies have reported that terrigenous organic carbon supports disproportionately high zooplankton production, others have suggested that phytoplankton preferentially supports zooplankton production in aquatic ecosystems. Quantification of zooplankton food sources using ambient stable carbon isotopic signatures is difficult because of the inherent difficulty in directly measuring the δ¹³C of phytoplankton, and the narrow and overlapping range of phytoplankton and terrigenous organic matter δ¹³C signatures, especially in freshwater systems. The objectives of this study were (1) to use isotopic composition to assess the food sources of mesozooplankton in Lake Superior, and (2) to investigate food sources of zooplankton in a suite of other aquatic systems.  Natural abundance radiocarbon (∆¹⁴C) and stable isotope (δ¹³C, δ¹⁵N) analyses were applied to show that zooplankton in Lake Superior selectively incorporate recently-fixed, locally-produced (autochthonous) organic carbon even though other carbon sources are readily available.  Estimates from Bayesian isotopic modeling based on ∆¹⁴C and δ¹³C values show that the average lakewide median contributions of recent in-lake primary production and terrestrial, sedimentary, and bacterial organic carbon to the bulk POM in Lake Superior were 58%, 5%, 33%, and 3%, respectively. However, isotopic modeling estimates also show that recent in situ production contributed a disproportionately large amount (median, 91%) of the carbon in mesozooplankton biomass in Lake Superior. Although terrigenous organic carbon and old organic carbon from resuspended sediments were significant portions (median, 38%) of the available basal food resources, these contributed only a small amount to mesozooplankton biomass (median, 3% from sedimentary organic carbon and 3% from terrigenous organic carbon). The isotopic investigation shows that intermediate trophic-level mesozooplankton in Lake Superior prefer to incorporate fresh autochthonous food, despite the availability of other organic carbon sources, and that upper trophic levels are likely not supported by terrestrial and/or resuspended-sediment OC subsidies to the carbon cycle.    Comparison of zooplankton food sources based on their radiocarbon composition showed that terrigenous organic carbon was relatively more important in rivers and small lakes, and the proportion of terrestrially-derived material used by zooplankton correlated with the hydrologic residence time and the ratio of basin area to water surface area.  Further research should focus on the catabolic metabolism of mesozooplankton and both anabolic and catabolic metabolism in the microbial loop to further our understanding of such subsidies in the carbon cycle and energy transfer.

Diversity and Distribution of Zooplankton in Pandu Lake, Telangana, India| Chapter 2 | Research Aspects in Biological Science Vol. 7

 To assess the trophic state of Pandu Lake in Bodhan, Telangana, India, and to gain new knowledge about its ecology, a study on the distribution and abundance of zooplankton was carried out between August 2002 and July 2004. In an aquatic ecosystem, zooplankton plays a vital role in the trophic structure and is primarily in charge of energy transfer. The order of zooplankton abundance in the Pandu Lake was Rotifera > Ostracoda > Copepoda > Diptera > Cladocera. Rotifers had the greatest diversity and population density of any zooplankton over the duration of the research. Results demonstrated Pandu Lake's eutrophic status. The planktons are useful indicators of the quality of the water in Pandu Lake, and their ecological relevance suggests that the nutrient load, a major contributor to the eutrophication process, should be controlled.

Determining the Diversity and Density of Zooplanktons of Kolar Reservoir in India | Chapter 7 | Research Aspects in Biological Science Vol. 3

The purpose of this research is to find out how diverse and dense the zooplankton is in the Kolar reservoir in Bhopal, Madhya Pradesh. The density of the planktons was determined using samples obtained from three different reservoir sampling points. In the reservoir during the research year of 2007-2008, there were three main kinds of zooplanktons. Their scientific names are Protozoa, Rotifera, and Crustacea. With 950org/l, Crustacea had the highest average density. The highest density was discovered in June, while the lowest density was discovered in November. Zooplanktons are significant bioindicators of water pollution, hence studying them is crucial for every water body.

Study on Zooplankton Diversity of Cauvery River in Erode District, Tamil Nadu | Chapter 14 | New Visions in Biological Science Vol. 1

 The Cauvery River is the source of water for several places in Tamilnadu. As a result of poor textile effluent control, the Erode District is extremely polluted. The goal of this study was to determine the Cauvery River's quality in Erode. Planktons are the principal food supply for aquatic ecosystems. Zooplankton diversity is one of the most important ecological factors for determining water quality. From July to November 2018, the goal of this study was to look at the diversity of Zooplankton in the Cauvery River in Erode, and the results were reported on a regular basis. Zooplankton diversity is a key indicator for the river ecology, and it is influenced by river water quality, according to the research. Rotifers are the most commonly observed and significant zooplankton species in the Cauvery River. Variations in biodiversity in a body of water can be linked to water quality. Zooplanktons are also good markers of biological water quality.

Marine Zooplankton from Bashayer Marine Terminal and Abo Hashish along the Sudanese Red Sea Coast | Chapter 1 | Recent Research Advances in Biology Vol. 2

 The maximum number of zooplankton groups reported from the Red Sea Coast of Sudan was 20 from the marine terminal of Bashayer. Farranula, Medusae and Sagitta were the first zooplankton groups reported in Bashayer in 2016. As they were reported in 2018, they managed to develop them. The small number of plankton groups in three randomly investigated oil tankers contained in ballast water 5, 10 and 15 Cell/L is possibly due to mechanical destruction and/or biological destructive factors during the voyage. Multiple tests of regression showed statistically significant differences in mean (p<0.05) In the Tires Plant and Sea Land areas, zooplankton count and negligible variations in fish (p>0.05)  Market, open sea, port entry and Marine Science and Fisheries Faculty areas. Station at Sea  Land showed statistically significant differences in salinity (p<0.05), while the majority of the stations showed statistically significant differences (p<0.05).  Salinity of 40' exhibited. Therefore, zooplankton populations will serve as bio-indicators of different human beings.  Input into the marine ecosystem and environmental inputs.
