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

open access: yesEnvironmental 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 ...

Population Genomics Reveals Small‐Scale Metapopulation Structure of Two Strictly Aquatic Keystone Species in a Recently Restored Urban River System (Emscher, Germany)

open access: yesEcology and Evolution, Volume 15, Issue 4, April 2025.
The study used high‐resolution genetic markers to analyze the metapopulation structure of two aquatic amphipod species, Gammarus pulex and Gammarus fossarum, in an urban river catchment (Emscher, Germany). Strong metapopulation structure was identified, primarily influenced by catchment affiliation, wastewater, in‐stream barriers, and recolonization ...

Linking behavioural variance to environmental heterogeneity: Variance decomposition in surface versus cave isopod populations

open access: yesFunctional Ecology, Volume 39, Issue 3, Page 737-755, March 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract A longstanding question in evolutionary biology is how within‐population phenotypic variation is maintained under natural selection. The fluctuating selection hypothesis suggests that genetic and phenotypic variation scales with fluctuations in selection over space and ...

Experience in controlling Asellus aquaticus in water distribution systems

open access: yes, 2001
Asellus aquaticus is one of the nuisance organisms found in water distribution systems. Case studies of operations aimed at control of this crustacean and its disinfestation, carried out in two water distribution networks: in Pevensey Bay (Eastbourne, UK)

TELOMERIC SEQUENCES OF ASELLUS-AQUATICUS (CRUST ISOP)

open access: yes, 1994
The repeated sequence TTAGGG is present at all tested vertebrate telomeres including those of humans and at the telomeres of evolutionarily very distant organisms such as trypanosomes and slime moulds. We tested for the presence of this sequence in the

Seasonal diet pattern of non-native tubenose goby (Proterorhinus semilunaris) in a lowland reservoir (Mušov, Czech Republic)

open access: yesKnowledge and Management of Aquatic Ecosystems, 2010
The tubenose goby (Proterorhinus semilunaris) is a gobiid species currently extending its area of distribution in Central Europe. The objective of the study was to evaluate the annual pattern of its feeding habits in the newly colonised habitats of the ...

Contrasting sensitivities to toxicants of the freshwater amphipods Gammarus pulex and G. fossarum [PDF]

open access: yes, 2010
Amphipods are an important component of freshwater ecosystems. They are very often used in ecotoxicology, particularly the freshwater amphipod Gammarus pulex.

Bioaccumulation of palladium, platinum and rhodium from urban particulates and sediments by the freshwater isopod Asellus aquaticus

open access: yes, 2001
The three-way catalytic converters introduced to oxidize and reduce gaseous automobile emissions represent a source of platinum group elements (PGEs), in particular platinum, palladium and rhodium, to the urban environment.

Fish and macrozoobenthos in the Vlára stream drainage area (Bílé Karpaty Mountains)

open access: yesCzech Journal of Animal Science, 2007
Fish fauna and macrozoobenthos were surveyed at 51 and 32 sampling sites, respectively, in mountain and submountain streams of the Vlara stream drainage area in the Bílé Karpaty Mountains. The aim of the study was to bring wide knowledge of their aquatic

Species-genetic diversity correlation in a metacommunity of urban pond invertebrates

open access: yesBasic and Applied Ecology
Understanding patterns of species-genetic diversity correlations (SGDC) is important for conservation purposes because it allows us to infer whether conservation of species diversity (SD) influences conservation of genetic diversity (GD) and the other ...
