Responses of Zooplankton Community to Environmental Factors and Phytoplankton Biomass in Lake Nansihu, China

Wang Tian1, Huayong Zhang1,*, Jian Zhang2, Lei Zhao1, Mingsheng Miao3 and Hai Huang1

...">Seasonal variations of zooplankton community structure and their relationships with both environmental factors and phytoplankton biomass are investigated in Lake Nansihu. A total of 76 zooplankton species were identified in the lake, including 17 protozoa, 36 rotifera, 12 cladocera and 11 copepods species, respectively. Zooplankton species richness changed slightly in the four seasons bu...
Studies on Seasonal and Spatial Distribution of Zooplankton Communities and Their Diversity Indices at Chashma Lake, Pakistan
Huma Ayub1,Iftikhar Ahmad2, Syed Lal Shah3,*, Muhammad Zafarullah Bhatti4, Nuzhat Shafi5 and Mazhar Qayyum1
... spatial distribution of zooplankton species at Chashma Lake during June 2014 to May 2015. The samples were collected from three partially separated stations of the Chashma Lake on a monthly basis. A total 42 species of zooplankton were identified from the Chashma Lake belonging to three taxa viz.; copepoda, rotifera and cladocera. The diversity of the zooplankton species in the lak...
Environmental Determinants of Zooplankton Community in the Damietta Estuary of the Nile River, Egypt

...nting 39.4% of the total zooplankton abundance. Copepods and their larval stages contributed 36.2%. Rotifers ranked the third important group (12.6%). Protozoa contributed 10.6% of the total community. According to the Canonical Correspondence Analysis (CCA), the variations in the species data were significantly (P< 0.05) related to salinity, temperature, phosphate concentration and phytoplankton biomass. The main spatial gradients along the estuary were as...
Biodiversity and Abundance of Plankton Communities along the Coastal Waters of Gulf of Aqaba, Saudi Arabia
Mohsen M. El-Sherbiny1,2,*, Reny P. Devassy1, Erinn M. Muller3, Abdulmohsin A. Al-Sofyani1 and Ali M. Al-Aidaroos1
...ability of the major mesozooplankton taxon, Copepoda was studied with respect to the prevailing hydrographic conditions along the coastal waters of Gulf of Aqaba, Saudi Arabia during the summer period. Conspicuous stratification was evident in the water column while nutrient distribution highlighted the oligotrophic nature of the region. Nitrate showed a notable increase in the deeper layers of almost all the stations and towards the south. Chlorophyll a
Ecology and Diversity of Freshwater Zooplankton in Laghouat Province (Algeria) and their Relationship with Environmental Factors

...ribution and richness of zooplankton on the Wadi M’zi River from November 2018 to October 2019, samples were collected on a monthly basis from four stations. Thirty-three zooplankton species belonging to four taxa have been described from the Wadi M’zi River; Copepoda, Rotifera, Cladocera and Nematoda. The following diversity indexes were used to measure the diversity of zooplankton
A Preliminary Investigation of Phytoplankton and Zooplankton Diversity in Marine Water Ponds, Thatta, Sindh, Pakistan

Asma Fatima*, Ghulam Abbas and Shahnaz Rashid

...luding phytoplankton and zooplankton diversity of marine water ponds at Thatta district, Sindh, Pakistan. Water samples were collected monthly (Jan-Dec, 2019) from different sites of the ponds and studied the total abundance of plankton in each month. During the study, physicochemical parameters of the pond water like temperature, pH, dissolved oxygen, salinity, transparency, ammonia, phosphates, nitrates, potassium, calcium, total alkalinity and total hardnes...
Fish Diversity and Water Quality in Different Zones of Upper River Indus Basin, Pakistan

Zaidi Zona, Zulfiqar Ali*, Rida Ahmad and Irfan Zainab

...phytoplankton (n=31) and zooplankton (n=3) species in study area. In total, 37 fish species were found in the study area, with species richness rising from zone one (n =10) to zone five (n =33). Altogether, the fish diversity represents 25 genera and 13 families. To analyze the data, principal component analysis (PCA) was done by using XLSTAT and excel 2019 to study the factors affecting the water quality. The eigenvalues obtained after PCA from zone 1 to zone...
Seasonal Variation in Aquatic Biota in Relation to Physico-Chemical Parameters of Sonmiani, Balochistan, Pakistan

Nasratullah Baloch1*, Naeem Tariq Narejo2, Hamida Narejo3, Muhammad Farooq Hassan4, Muhammad Hanif Chandio5, Faheem Saddar6, Dharti Shahnawaz Thebo7, Ghulam Abbas8 and Shahnaz Rashid8

... variation in phyto- and zooplankton (aquatic biota) in relation to physico-chemical parameters from Sonmiani Bay, Balochistan, Pakistan was studied from January to December 2016. For month-wise analysis of zoo- and phytoplankton was performed by using net of 25 µm mesh size. For the qualitative and computable examination of planktons, the 50 liters of bay water was strained and residue fixed with 5% formalin in sampling bottles. The 99 genera of both th...

...including phytoplankton, zooplankton and bacteria, and perform a critical role in moving materials from upper levels to deep Ocean. Intriguingly, findings of AHL signaling molecules in marine snow aggregates and associated microbial cells have been attributed to play a crucial role in dissociation of these large carbon rich particles with a profound impact on marine food webs along with biogeochemical cycles in marine environment. This mini review highlights t...
