“…Different species show various tolerances to increasing or decreasing temperature ranges, with particularly sensitive individuals being eliminated [9,10]. Low pH promotes a decreased zooplankton abundance, decreased biodiversity, and the extinction of some species, whereas alkaline conditions associated with high primary production promote zooplankton development and abundance [11][12][13][14][15]. The availability of light determines the producer's distribution, which indirectly impacts the diversity and distribution of animals.…”

As an intermediary connection between primary producers and higher trophic levels, zooplankton are an important component of the aquatic food chain, contributing significantly to aquatic biological productivity. This study describes the zooplankton diversity and community structure, as well as their relationships with ecological factors, in homestead ponds of a coastal district along the northern Bay of Bengal region. Significant differences (p < 0.05) were detected in the mean values of temperature, pH, DO, TDS, transparency, and phosphates from the ponds during December 2020, but no significant differences were found in the nitrate levels. However, no significant variances in the ecological parameters between months were found due to the study taking place in the same season. Sixteen zooplankton species, representing four groups, were found in the study area, with the highest mean abundance of 301.19 ± 40.55 ind./L recorded in February 2021 and the lowest of 293.02 ± 21.13 ind./L recorded in December 2020. The diversity (H’), evenness (e), richness (J), and dominance (D) ranged from 2.49 to 2.12, from 0.93 to 0.84, from 2.05 to 1.56, and from 0.13 to 0.09, respectively. Based on the SIMPER analysis, Diaptomus gracilis and Brachionus calyciflorus were found to be significant contributors (>10%) to the zooplankton community structure in different months. The ANOSIM results revealed that 10 species of zooplankton were significant contributors based on their average dissimilarity. The canonical correspondence analysis (CCA) identified that pH, transparency, nitrates, and phosphates have a significant impact on the abundance of zooplankton species in the homestead ponds in the study area.

“…pH, which is important for the life cycle of zooplankton, can affect zooplankton abundance; Alkaline conditions associated with high primary production favor zooplankton growth and abundance (Bednarz et al, 2002;Mustapha, 2009), while low pH results in reduced zooplankton abundance, biodiversity, and extinction of some species (Ivanova and Kazantseva, 2006). It is stated in The Ministry of Forestry and Water Affairs of the Republic of Turkey (OSIB, 2015) that the pH values of fresh water to be between 6.00 and 9.00 in the regulation of Quality Criteria for Turkish Surface Water Resources.…”

Water quality parameters were found to be within normal limits for most aquatic organisms. The annual average water temperature, dissolved oxygen, pH and conductivity were 17.64 ± 7.64 °C, 7.92±0.18, 9.26 ± 1.00 mgL-1, 368.52±24.69 µS cm-1 respectivelly. In the study, 66 rotifers (75.86%), 15 cladocerans (17.24%) and 6 copepod species (6.90%) were recorded in the reservoir. A total of 22 families from Rotifera, 5 families from Cladocera and 2 families from Copepoda were recorded. Brachionidae and Lecanidae from the Rotifera group containing the most species were the richest families with 10 species each. They were found to be the most abundant family with 8 species of Chydoridae from Cladocera and 5 species of Cyclopoidae from Copepodae. The most widely distributed rotifers found in all seasons during the study, Kellicottia longispina, Keratella cochlearis, Asplanchna priodonta, Testudinella emarginula, Ascomorpha ovalis, Gastropus stylifer, Filinia longiseta, Trichotria pocillum, Polyarthra dolichoptera, Polyarthra vulgaris, Synchaeta oblonga, Rotaria rotatoria. Ceriodaphnia pulchella, Bosmina longirostris, Chydorus sphaericus from Cladocera, and Cyclops vicinus, Macrocyclops albidus, Paracyclops fimbriatus and Nitokra hibernica from Copepoda had the widest range of distribution.
