Abstract

Sagartaal is located in Budaun with geographical coordinates 28.0512°N and 79.1305°E in Nawada region, Uttar Pradesh, Uttar Pradesh, India. Understanding the composition, diversity, and abundance of the zooplankton is vital for better utilization of such waterbodies. The present study was carried out from October 2022 to September 2023. A total of 24 species belonging to 16 species of Rotifera, 4 species of Cladocera, 2 species of Copepoda, and 2 species of Ostracoda were recorded. The prominent species were Brachionus forficula, B. calyciflourus, Keratella cochlearis, Simocephalus sp., Cyclops sp., and Mesocyclops sp. Zooplankton showed seasonal variations in their species composition, abundance, and diversity concerning water temperature, pH, total alkalinity, dissolved oxygen, and hardness. The zooplankton density was recorded as maximum in winter and minimum in monsoon. Statistically, zooplankton shows significant correlations as Rotifera with EC, BOD (r =− 0.50; − 0.58, respectively); while with total hardness (r = 0.75); Cladocera with DO (r = 0.53), alkalinity (r = 0.57), nitrate (r = 0.56), and phosphate (r = − 0.49). The highest Shannon index (2.83) was obtained for summer, due to the lowest value of the dominance index (0.07) for this season. More studies are warranted on Monitoring such ecosystems as Sagartaal to understand the effects of anthropogenic pressure on zooplankton's community structure, can help in identifying the indicator species to formulate effective conservation planning.

印度北方邦布达恩县 Sagartaal 的浮游动物组成、丰度和多样性

萨加尔塔尔位于印度北方邦纳瓦达地区的布达恩，地理坐标为 28.0512°N，79.1305°E。了解浮游动物的组成、多样性和丰度对于更好地利用此类水体至关重要。本研究于 2022 年 10 月至 2023 年 9 月进行。共记录到 24 种浮游动物，包括 16 种轮虫、4 种栉孔虫、2 种桡足类和 2 种尾足类。浮游动物的种类组成、丰度和多样性随水温、pH 值、总碱度、溶解氧和硬度而呈现季节性变化。浮游动物密度在冬季最高，在季风季节最低。据统计，浮游动物与 EC、BOD（r =- 0.50；- 0.58）、总硬度（r = 0.75）、Cladocera 与溶解氧（r = 0.53）、碱度（r = 0.57）、硝酸盐（r = 0.56）和磷酸盐（r = - 0.49）有明显的相关性。夏季的香农指数（2.83）最高，因为该季节的优势指数（0.07）最低。有必要对 Sagartaal 等生态系统进行更多的监测研究，以了解人为压力对浮游动物群落结构的影响，这有助于确定指标物种，从而制定有效的保护规划。

期刊介绍： Aquatic Ecology publishes timely, peer-reviewed original papers relating to the ecology of fresh, brackish, estuarine and marine environments. Papers on fundamental and applied novel research in both the field and the laboratory, including descriptive or experimental studies, will be included in the journal. Preference will be given to studies that address timely and current topics and are integrative and critical in approach. We discourage papers that describe presence and abundance of aquatic biota in local habitats as well as papers that are pure systematic. The journal provides a forum for the aquatic ecologist - limnologist and oceanologist alike- to discuss ecological issues related to processes and structures at different integration levels from individuals to populations, to communities and entire ecosystems.
