Crustacean zooplankton dynamics in a natural riverine lake, Upper Mississippi River

Journal of Freshwater Ecology, 2017
Zooplankton communities in riverine systems are typically thought to be driven by abiotic forces. However, recent studies have shown that biological controls are capable of structuring these communities in large rivers and may become more influential as ...

Zooplankton Biomass in Ponds - Determination of Biovolume and Dry Weight

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2023
The aim of this study was to evaluate the possibility of using simple screening methods to determine zooplankton biomass in ponds. Among the applicable methods, we selected sedimentation determination of wet biomass and dry biomass determination.

Synergistic Impacts of Co‐Exposure to Microplastics and Vibrio harveyi on the Immune and Stress Responses of the Big‐Belly Seahorse Hippocampus abdominalis

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
Synergistic effects of microplastic and Vibrio harveyi co‐exposure on big‐belly seahorse (Hippocampus abdominalis). Seahorses were exposed to microplastics (50 beads/L of 0.2 μm SMP and 1.0 μm LMP) and injected with V. harveyi (1 × 103 CFU/mL).

Spatial and Seasonal Variations in the Stable Isotope Values and Trophic Positions of Dominant Zooplankton Groups in Jiaozhou Bay, China

Frontiers in Marine Science, 2022
The spatial and seasonal distributions of stable carbon and nitrogen isotopes (δ13C and δ15N) in dominant zooplankton groups were investigated in Jiaozhou Bay.

Differences in the trophic ecology of micronekton driven by diel vertical migration. [PDF]

, 2019
Many species of micronekton perform diel vertical migrations (DVMs), which ultimately contributes to carbon export to the deep sea. However, not all micronekton species perform DVM, and the nonmigrators, which are often understudied, have different ...

The nutritional status of zooplankton in a tropical reservoir: effects of food quality and community structure

Brazilian Journal of Biology
The temporal variability of energetic reserves of zooplankton in the eutrophic Pampulha reservoir was investigated during two successive annual cycles. The effects of dominance of large filter-feeding cladocerans (Daphnia) and the occurrence of massive ...

Invertebrate communities in northern Lake Victoria, with reference to their potential for fishery production [PDF]

, 1999
The zooplankton and macrobenthic communities of Lake Victoria were sampled by lift net and Ponar grab, respectively. The zooplankton comprised copepods and cladocerans, rotifers and aquatic insect larvae. Most taxa exhibited wide distribution in the lake,
