Speciation in Daphnia [PDF]

open access: yesMolecular Ecology, 2020
AbstractThe microcrustaceanDaphniais arguably one of the most studied zooplankton species, having a well understood ecology, life history, and a relatively well studied evolutionary history. Despite this wealth of knowledge, species boundaries within closely related species in this genus often remain elusive and the major evolutionary forces driving ...

Defining Quality Criteria for Nanoplastic Hazard Evaluation: The Case of Polystyrene Nanoplastics and Aquatic Invertebrate Daphnia spp.

open access: yesNanomaterials, 2023
Polystyrene nanoparticles are the most investigated type of nanoplastics in environmental hazard studies. It remains unclear whether nanoplastic particles pose a hazard towards aquatic organisms.

Mycosporine-Like Amino Acids (MAAs) in Zooplankton

open access: yesMarine Drugs, 2020
Organisms have different adaptations to avoid damage from ultraviolet radiation and one such adaptation is the accumulation of mycosporine-like amino acids (MAAs).

Low-toxic herbicides Roundup and Atrazine disturb free radical processes in Daphnia in environmentally relevant concentrations

open access: yesEXCLI Journal : Experimental and Clinical Sciences, 2022
The use of glyphosate-based Roundup and triazine herbicide Atrazine has increased markedly in last decades. Thus, it is important to evaluate toxic effects of these herbicides to non-targeted organisms such as zooplankton to understand their safety ...

Trophic niche breadth of pond zooplankton species using stable isotope analysis and the relationship with the abiotic and biotic factors [PDF]

open access: yesRoyal Society Open Science, 2019
Zooplankton species have different feeding habits, but the diversity of their food resources and the factors governing them are still largely unknown.

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.

Responses of a bacterial pathogen to phosphorus limitation of its aquatic invertebrate host [PDF]

open access: yes, 2008
Host nutrition is thought to affect the establishment, persistence, and severity of pathogenic infections. Nutrient-deficient foods possibly benefit pathogens by constraining host immune function or benefit hosts by limiting parasite growth and ...

Prey body size mediates the predation risk associated with being "odd" [PDF]

open access: yes, 2014
Despite selection pressures on prey animals to maintain phenotypically homogeneous groups, variation in phenotype within animal groups is commonly observed.

Zooplankton as ecosystem indicators and their effects on eutrophication in Lake Arekit (Ethiopia) – implication for freshwater habitat management

open access: yesJournal of Freshwater Ecology, 2023
This paper examines the zooplankton abundance and composition along with various environmental factors in Lake Arekit – a shallow freshwater habitat in Ethiopia’s rift valley system. Zooplankton samples and specific environmental data were collected by a
