Assessment of RNA extraction protocols from cladocerans [PDF]

open access: yesPLOS ONE, 2022
The usage of cladocerans as non-model organisms in ecotoxicological and risk assessment studies has intensified in recent years due to their ecological importance in aquatic ecosystems. The molecular assessment such as gene expression analysis has been introduced in ecotoxicological and risk assessment to link the expression of specific genes to a ...

Zooplankton Community Stability and Environmental Filtering in a Shallow Eutrophic Lake. [PDF]

open access: yesEcol Evol
Anthropogenic pressures led to zooplankton shift to small‐bodied dominance, not structural reorganization. Integrated management is crucial for long‐term resilience. ABSTRACT Zooplankton are key regulators of trophic interactions and nutrient cycling in shallow eutrophic lakes and are sensitive indicators of ecological responses to anthropogenic ...

Effects of predation by Hydra (Cnidaria) on cladocerans (Crustacea: Cladocera)

open access: yesJournal of Limnology, 2016
Planktonic cladocerans have evolved different strategies to avoid predation from vertebrates; these include changes in morphology, behavior, physiology, and/or life-history traits.

An overview of the contribution of studies with cladocerans to environmental stress research

open access: yesActa Limnologica Brasiliensia, 2015
Cladocerans are microcrustaceans component of the zooplankton in a wide array of aquatic ecosystems. These organisms, in particular the genus Daphnia, have been widely used model organisms in studies ranging from biomedical sciences to ecology.

Seasonal changes in the distribution and abundance of marine cladocerans of the Northwest Alboran Sea (Western Mediterranean), Spain [PDF]

open access: yesBrazilian Archives of Biology and Technology, 2011
The annual cycle of marine cladocerans was studied over six years from 1994 to 1999 within the frame of the monitoring Project ECOMALAGA at a nine stations in the NW of the Alboran Sea, with the aim of assessing seasonal patterns and interannual trends ...

DNA Metabarcoding Reveals Unexpected Predator-Prey-Microbial Dynamics in the Southern Right Whale (Eubalaena australis). [PDF]

open access: yesMol Ecol
ABSTRACT Southern right whale (Eubalaena australis; SRW) populations are recovering from the impacts of commercial whaling, however, recovery has been spatially variable, with strong associations between reproduction and prey availability. The diet of SRWs has not been widely examined, and with SRW foraging shifting away from high‐latitude foraging ...

Crustacean Zooplankton Ingestion of Potentially Toxic Microcystis: In Situ Estimation Using mcyE Gene Gut Content Detection in a Large Temperate Eutrophic Lake [PDF]

open access: yesToxins
Grazing by zooplankton can regulate bloom-forming cyanobacteria but can also transfer toxin-producing cells, as well as toxic metabolites, to the food web.

Grazing Responses of Distinct-Sized Tropical Cladocerans to Different Filamentous Sizes of the Cyanobacterium Dolichospermum planctonicum [PDF]

open access: yesMicroorganisms
Cyanobacterial blooms directly influence the structure and function of zooplankton communities; however, the trophic interactions between small tropical cladocerans and the cyanobacterium Dolichospermum are still poorly understood.

The planktonic food web in the Gulf of Naples based on the analysis of carbon and nitrogen stable isotope ratios

open access: yesMarine Ecology, EarlyView., 2023
Abstract Plankton play a key role in marine food webs by producing and transferring organic matter and energy to higher trophic levels. To define the trophic structure and interactions within the planktonic communities in the Gulf of Naples, we determined carbon and nitrogen stable isotope ratios in particulate organic matter (POM, <20 μm ...
