Feeding in predator naïve crayfish is influenced by cues from a fish predator

Scientific Reports, 2023
In this study, we experimentally evaluated how the feeding behaviour of marbled crayfish Procambarus virginalis is influenced by cues from conspecifics and the round goby Neogobius melanostomus, a fish predator, in tanks that permitted chemical ...

Drivers of the range expansion of the European catfish (Silurus glanis) within its native distribution

Journal of Fish Biology, Volume 107, Issue 3, Page 1030-1044, September 2025.
Abstract The European catfish Silurus glanis L. continues to spread as an invasive species in Europe. Meanwhile, increasing abundance and range expansions are also suspected within its native distribution. The objective of this study was to characterize the feeding, growth and abundance of S.

The effect of glyphosate-based herbicide on aquatic organisms – a case study

Limnological Review, 2013
The non-selective, post-emergence herbicides based on glyphosate [N-(phosphonomethyl) glycine] are one of the most widely used pesticides in agriculture, urban areas and forestry.

Submersed Aquatic Vegetation Enhances Density and Diversity of Epifaunal Invertebrates Compared to Filamentous Mats in the Central Baltic Sea

Ecology and Evolution, Volume 15, Issue 6, June 2025.
This study evaluates the relative importance of Submersed Aquatic Vegetation (SAV) and filamentous mats in shaping epifaunal invertebrate communities in the central Baltic Sea. Our results showed that diversity, vertical structure, and biomass of SAV were all positively associated with higher total epifaunal abundance and greater abundance of ...

Multi‐Decadal Trends in Northern Lakes Show Contrasting Responses of Phytoplankton and Benthic Macroinvertebrates to Climate Change

Global Change Biology, Volume 31, Issue 6, June 2025.
Northern lakes are changing due to climate warming and landscape alterations. Three decades of time‐series data for 110 Swedish lakes showed that phytoplankton and bottom‐dwelling littoral and profundal faunal assemblages are responding to these environmental changes. Yet, the responses differed among the three organism groups.

Calibrating Predicted Mixture Toxic Pressure to Observed Biodiversity Loss in Aquatic Ecosystems

Global Change Biology, Volume 31, Issue 6, June 2025.
This study bridges the gap between lab‐based chemical toxicity estimates and real‐world biodiversity loss in freshwater ecosystems. Findings show that rising toxic pressure from chemical mixtures is closely linked to declining species diversity, even at levels considered safe.

Animal standardisation for mixed species ecotoxicological studies: Establishing a laboratory breeding programme for Gammarus pulex and Asellus aquaticus Estandarización animal para estudios ecotoxicológicos mixtos: establecimiento de un programa de reprod [PDF]

, 2020
This paper outlines how to establish a standardised laboratory breeding programme for Gammarus pulex and Asellus aquaticus. Wild Gammarus pulex and Asellus aquaticus specimens were captured from an unpolluted river source and used as founder populations ...

Estimating intraspecific genetic diversity from community DNA metabarcoding data [PDF]

PeerJ, 2018
Background DNA metabarcoding is used to generate species composition data for entire communities. However, sequencing errors in high-throughput sequencing instruments are fairly common, usually requiring reads to be clustered into operational taxonomic ...

Capture—Incubate—Release: An Animal‐Friendly Approach to Assess Local Aquatic Macroinvertebrate Species Diversity Through Environmental DNA Metabarcoding

Environmental DNA, Volume 7, Issue 3, May–June 2025.
We assessed whether we can combine the advantages of both bulk and eDNA metabarcoding, that is, obtaining a local signal and being minimally invasive, to improve local invertebrate detections in streams using water samples. We quantified eDNA release over time after a short incubation in water for single species using qPCR and for bulk samples using ...
