Impacts of late‐Holocene climate variability and watershed‐lake interactions on diatom communities in Lac Brûlé, Québec

open access: yesEcosphere, 2017
A high‐resolution diatom analysis of a varved sediment sequence from Lac Brûlé, southwestern Québec, was used to study temporal patterns of environmental change in the late Holocene. Key periods of interest in the record included the Medieval Warm Period

Varying degradation of subfossil Daphnia longispina during the past 250 years and the discovery of fossil helmet-type head shields: preliminary results

open access: yesAdvances in Oceanography and Limnology, 2016
Zooplankton are regarded as a good indicator of environmental change, but comprehensive monitoring programs including  zooplankton are uncommon and only rarely extend over longer periods of time.

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).

Desiccation to DNA: Bulk DNA Metabarcoding of Macroinvertebrate Egg Banks via Sugar‐Flotation Enhances Biodiversity Surveys of Dry Salt Lakes

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
Ephemeral salt lakes in arid Australia contain hidden macroinvertebrate biodiversity in sediment egg banks, but traditional artificial rehydration surveys may miss taxa with specific or poorly understood hatching requirements. This study found that sugar‐flotation followed by DNA metabarcoding greatly improved detection of resting‐stage taxa compared ...

Impact of water level fluctuation in the shaping of zooplankton assemblage in a shallow lake.

open access: yesCroatian Journal of Fisheries, 2018
Shallow lakes are strongly affected by global climate changes reflected in significant parameters of ecosystem deterioration, i.e. biodiversity decrease, and water turbidity.

New Records of Cladocera (Crustacea: Anomopoda) from Laguna Navío Quebrado, La Guajira Department, Colombia

open access: yesNauplius, 2014
Zooplankton plays key roles in structuring interactions in aquatic communities but often remain undescribed in many water systems. This paper reports seventeen species of the Cladocera (Crustacea: Branchiopoda) from Laguna de Navío Quebrado, all of them ...

Diversity of freshwater Cladoceran species (Crustacea: Branchiopoda) in South Korea

open access: yesJournal of Ecology and Environment, 2015
We investigated cladoceran fauna from 71 study areas in South Korea. Sixty-two taxa were found, of which there were 30 planktonic and 25 littoral-benthic cladoceran species. In the present study, taxa of cladocera were

Understanding Significance of Cladocera biodiversity potential of Upper Tisza region

open access: yes, 2021
Analysis of the cladocera diversity in oxbow lakes. Cladocera are known to be sensitive organism to slight environmental changes. Additionally, they occupy the middle of the trophic level structure hence they can be used to determine abundance or lack of
