Experimental analysis of polymorphic microsatellite loci in Cladocera: mixed breeding strategy and population dynamics [PDF]

open access: yesПисьма в Вавиловский журнал генетики и селекции
The aim of this work is to identify polymorphic loci in Daphnia genomes using genome sequence analysis and experimental analysis of real accessions of samples collected in nature. We use primers predicted by an algorithm for DNA amplification from Daph-

Environmental DNA tracks zooplankton population dynamics in experimental mesocosms

open access: yesEnvironmental DNA, 2023
Environmental DNA (eDNA) holds notable potential for biomonitoring and ecological research. However, its utility for quantifying temporal changes in abundance, biomass, and diversity remains contentious.

Apprendre à voir, apprendre à dire

open access: yesArts et Savoirs, 2017
The emergence of a microscopic science in the 18th century was marked by an attempt to standardize the methods of observation and also of description. How can these methods be shared?

Food quantity and quality shapes reproductive strategies of Daphnia

open access: yesEcology and Evolution, 2022
In freshwater environments, one of the challenges aquatic grazers face are periods of suboptimal food quantity and quality. In a life table experiment, the effects of food quantity (a gradient of algae concentration) and quality (a diet of cyanobacteria)

Evaluation of Possible Causes of Non-Predatory Mortality of Crustacean Zooplankton in a Small Siberian Reservoir [PDF]

open access: yesЖурнал Сибирского федерального университета: Серия Биология, 2008
Non-predatory specific mortality (NPSM) of dominant zooplankton species, Daphnia (longispina group) and Cyclops vicinus, was estimated during 1997-2000 sampling seasons on the basis of a new direct method: live/dead sorting and sediment trap measurements.

Clean-up of bodies of water contaminated by heavy metals using dead and live hyperaccumulators (flowering plants and algae)

open access: yesEQA
The pervasive issue of water contamination by heavy metals poses significant environmental and public health challenges, requiring innovative and effective remediation strategies. This study aims to compare the use of dead and live hyperaccumulators that

The Toxicity of Silver Nanoparticles (AgNPs) to Three Freshwater Invertebrates With Different Life Strategies: Hydra vulgaris, Daphnia carinata, and Paratya australiensis

open access: yesFrontiers in Environmental Science, 2018
The toxicity of manufactured nanoparticles varies greatly depending on the test species in consideration and estimates of toxicity may also be confounded by test media in which the organisms are cultured.

Evaluation of Abundance of Dead Crustacean Zooplankton in a Water Body Using Staining of the Samples by Aniline Blue Technique: Methodological Aspects [PDF]

open access: yesЖурнал Сибирского федерального университета: Серия Биология, 2008
Three long special experiments with killed by heating copepodites of Cyclops vicinus, Mesocyclops leuckarti (experiments 1 and 2), of Cyclops vicinus and Daphnia longispina group of different sizes and stages (experiment 3) were carried out to test an ...
