River connectivity restoration for upstream‐migrating European river lamprey: The efficacy of two horizontally‐mounted studded tile designs

open access: yesRiver Research and Applications, Volume 36, Issue 10, Page 2013-2023, December 2020., 2020
Abstract Many rivers are heavily fragmented, resulting from anthropogenic cross‐channel structures. Cost‐effective solutions are needed to restore habitat connectivity for migratory fishes, including those of conservation concern, such as the European river lamprey (Lampetra fluviatilis).

Infection of the Carpathian brook lamprey (Eudontomyzon danfordi Regan, 1911) with a dermocystid parasite in the Tisza River Basin, Hungary

open access: yesJournal of Fish Diseases, Volume 43, Issue 12, Page 1571-1577, December 2020., 2020
Abstract The Carpathian brook lamprey (Eudontomyzon danfordi Regan, 1911) is an endemic protected species of Cephalaspidomorphi in the Carpathian Basin. No parasites have become known from these jawless vertebrates to date. Here, the authors describe an infection from a single specimen manifesting in protuberant skin cysts 7–10 mm in diameter ...

Large‐scale molecular barcoding of prey DNA reveals predictors of intrapopulation feeding diversity in a marine predator

open access: yesEcology and Evolution, Volume 10, Issue 18, Page 9867-9885, September 2020., 2020
We estimated intrapopulation feeding diversity of harbor seals in the Salish Sea relative to sex, time, and location with a novel approach that combined molecular techniques, repeated cross‐sectional sampling of scat, and a specialization metric (within‐individual consistency in diet).

Conservation status of two endangered freshwater mussel species in Bavaria, Germany: Habitat quality, threats, and implications for conservation management

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 30, Issue 4, Page 647-661, April 2020., 2020
Abstract The freshwater pearl mussel (Margaritifera margaritifera) and the thick‐shelled river mussel (Unio crassus) are relatively widespread across Europe, but are strongly declining and are now protected by the European Habitats Directive. In the course of this study, 20 pearl mussel and 14 thick‐shelled river mussel streams in Bavaria, Germany ...

Rare Now and Rarer in the Future? Future Potential Distributions of the Endemic Lampetra zanandreai Showed Contractions in Its Suitable Areas

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT The Mediterranean basin is a hotspot of freshwater endemisms and restricted‐range species, which are among the most threatened worldwide. The Adriatic brook lamprey Lampetra zanandreai is a non‐parasitic, freshwater‐resident lamprey whose core distribution lies in the Po River basin (Northern Italy).

Hydropower Effluent as a Marine Pollutant; Impacts of River Regulation on Estuarine and Coastal Ecology

open access: yesRiver Research and Applications, Volume 41, Issue 9, Page 1789-1802, November 2025.
ABSTRACT The confluence of rivers with the ocean creates biological hotspots where temperature, salinity, and nutrients mix to provide excellent conditions for rearing, growth, and refuge to a multitude of organisms. Worldwide, estuaries are highly productive and biodiverse.
