Fine‐Scale Ecological Biomonitoring in a Large, Complex Agriculturally Impacted Watershed via eDNA Metabarcoding

open access: yesMolecular Ecology, Volume 35, Issue 10, May 2026.
ABSTRACT DNA‐based approaches utilizing high‐throughput sequencing (HTS) (e.g., DNA metabarcoding) have revolutionized ecological biomonitoring by providing higher sample throughput, greater reproducibility, and better cost‐benefits compared to traditional morphology‐based bioassessment studies.

Disentangling population strategies of two cladocerans adapted to different ultraviolet regimes

open access: yesEcology and Evolution, 2018
Zooplankton have evolved several mechanisms to deal with environmental threats, such as ultraviolet radiation (UVR), and in order to identify strategies inherent to organisms exposed to different UVR environments, we here examine life‐history traits of ...

Eltérő hasznosítású vizes élőhelyek Cladocera közösségek vizsgálata [PDF]

open access: yes, 2023
Globálisan elmondható, hogy a klíma változik, ami a hazai vizeinket is érinti, ennek hatására a vizeink vízszintje jelentősen ingadozik. A vizeink kellő intenzitású védelmének érdekében fontos a rendszeres monitorozás, hogy megértsük a rövid- és ...

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
