Prey Availability and Diet of Early Life Stages of Lake Whitefish (Coregonus clupeaformis) in the Fishing Islands of Lake Huron

Ecology of Freshwater Fish, Volume 34, Issue 3, July 2025.
ABSTRACT Declines in recruitment of lake whitefish (Coregonus clupeaformis) in the Laurentian Great Lakes have been attributed to a reduction in the amount of zooplankton prey available to young life stages, stemming from the ecosystem effects of invasive dreissenid mussels.

Two species of Alona (Cladocera, Chydoridae) new for Norway

Fauna Norvegica, 1987
The occurrence of two species of Alona, A. karelica Stenroos and A. weltneri Keilhack, new to Norway is noted and some environmental data provided. Some comments on the zoogeographical distribution of the Norwegian Cladocera are also given.

The cladoceran fauna of Nigeria : a checklist, review of literature and distribution [PDF]

, 1989
L'étude a porté sur 623 échantillons collectés entre 1971 et 1981 dans 145 stations en eau douce au Nigéria. On a dénombré 61 espèces et une sous-espèce pour 31 genres de Cladocères. Trente deux espèces sont nouvelles pour le Nigéria et 4 pour l'Afrique.

Weeding the Biodiversity Patch—A Mesocosm Study of Predation by Boeckella major (Copepoda: Calanoida) on Billabong Zooplankton

Freshwater Biology, Volume 70, Issue 7, July 2025.
ABSTRACT We carried out short‐term field experiments (duration 1–3 days) to study the impact of predation by natural densities of Boeckella major on zooplankton in Australian ephemeral billabongs (oxbow lakes). Predation reduced total zooplankton densities by 33.6%–91.9%.

Life history of Karualona muelleri (Richard, 1897) (Chydoridae, Aloninae)

Journal of Limnology, 2019
Many taxonomic issues still need to be solved for the family Chydoridae, but mainly in the subfamily Aloninae. The species Karualona muelleri is an example of a recent taxonomic redefinition, since it was decoupled from the genus Alona and translocated ...

Environmental Flows Rapidly Increase Zooplankton Abundance in a Regulated Lowland River

River Research and Applications, Volume 41, Issue 5, Page 1158-1168, June 2025.
ABSTRACT Zooplankton are important parts of the food web that support the survival of larval fish in floodplain rivers. Zooplankton abundance and community structure are sensitive to flow‐driven changes in the environment, which have been heavily impacted by river regulation with dams.

Occurrence of 'Antrobathynella stammeri' (Jakobi, 1954) (Crustacea: Syncarida: Bathynellidae) in the hyporheic zones of two English karst rivers [PDF]

, 2008
This paper reports the first records of Antrobathynella stammeri in the British Isles since 1985. Numerous individuals were observed in hyporheic water extracted from the River Skirfare (Yorkshire, UK), whilst, in an independent study, a single confirmed

Metabarcoding of freshwater invertebrates to detect the effects of a pesticide spill [PDF]

, 2017
Biomonitoring underpins the environmental assessment of freshwater ecosystems and guides management and conservation. Current methodology for surveys of (macro)invertebrates uses coarse taxonomic identification where species-level resolution is difficult

Estimating Rapid Diversity Changes During Acute Herbicide Contamination Using Environmental DNA

Environmental DNA, Volume 7, Issue 1, January–February 2025.
This study evaluates the use of environmental DNA metabarcoding to examine rapid changes in aquatic invertebrate communities following exposure to glyphosate‐based herbicide (GBH) in mesocosms under contrasted nutrient levels. We show a shift in community composition induced by GBH, and different impacts on zooplankton and insect family richness.
