Over 200,000 kilometers of free-flowing river habitat in Europe is altered due to impoundments (2023)
Journal Article
Parasiewicz, P., Belka, K., Łapińska, M., Ławniczak, K., Prus, P., Adamczyk, M., …Wiśniewolski, W. (2023). Over 200,000 kilometers of free-flowing river habitat in Europe is altered due to impoundments. Nature Communications, 14(1), Article 6289. https://doi.org/10.1038/s41467-023-40922-6

European rivers are disconnected by more than one million man-made barriers that physically limit aquatic species migration and contribute to modification of freshwater habitats. Here, a Conceptual Habitat Alteration Model for Ponding is developed to... Read More about Over 200,000 kilometers of free-flowing river habitat in Europe is altered due to impoundments.

A comprehensive assessment of stream fragmentation in Great Britain (2019)
Journal Article
Jones, J., Börger, L., Tummers, J., Jones, P., Lucas, M., Kerr, J., Kemp, P., Bizzi, S., Consuegra, S., Marcello, L., Vowles, A., Belletti, B., Verspoor, E., Van de Bund, W., Gough, P., & de Leaniz, C. G. (2019). A comprehensive assessment of stream fragmentation in Great Britain. Science of the Total Environment, 673, 756-762. https://doi.org/10.1016/j.scitotenv.2019.04.125

Artificial barriers are one of the main threats to river ecosystems, resulting in habitat fragmentation and loss of connectivity. Yet, the abundance and distribution of most artificial barriers, excluding high-head dams, is poorly documented. We prov...

Enhancing the upstream passage of river lamprey at a microhydropower installation using horizontally-mounted studded tiles (2018)
Journal Article
Tummers, J. S., Kerr, J. R., O'Brien, P., Kemp, P., & Lucas, M. C. (2018). Enhancing the upstream passage of river lamprey at a microhydropower installation using horizontally-mounted studded tiles. Ecological Engineering, 125, 87-97. https://doi.org/10.1016/j.ecoleng.2018.10.015

Passage performance of upstream-migrating lamprey (Lampetra fluviatilis) was compared between sections of a Crump flow-gauging weir with and without studded tiles, and at a bottom-baffle fishway, on the River Derwent, England. The effects of microhyd... Read More about Enhancing the upstream passage of river lamprey at a microhydropower installation using horizontally-mounted studded tiles.

Adaptive management in the context of barriers in European freshwater ecosystems (2017)
Journal Article
Birnie-Gauvin, K., Tummers, J., Lucas, M., & Aarestrup, K. (2017). Adaptive management in the context of barriers in European freshwater ecosystems. Journal of Environmental Management, 204(Part 1), 436-441. https://doi.org/10.1016/j.jenvman.2017.09.023

Many natural habitats have been modified to accommodate for the presence of humans and their needs. Infrastructures – such as hydroelectric dams, weirs, culverts and bridges – are now a common occurrence in streams and rivers across the world. As a r...

Evaluating the effectiveness of restoring longitudinal connectivity for stream fish communities: towards a more holistic approach (2016)
Journal Article
Tummers, J., Hudson, S., & Lucas, M. (2016). Evaluating the effectiveness of restoring longitudinal connectivity for stream fish communities: towards a more holistic approach. Science of the Total Environment, 569-570, 850-860. https://doi.org/10.1016/j.scitotenv.2016.06.207

A more holistic approach towards testing longitudinal connectivity restoration is needed in order to establish that intended ecological functions of such restoration are achieved. We illustrate the use of a multi-method scheme to evaluate the effecti...

Investigating the phenology of seaward migration of juvenile brown trout (Salmo trutta) in two European populations (2016)
Journal Article
Winter, E., Tummers, J., Aarestrup, K., Baktoft, H., & Lucas, M. (2016). Investigating the phenology of seaward migration of juvenile brown trout (Salmo trutta) in two European populations. Hydrobiologia, 775(1), 139-151. https://doi.org/10.1007/s10750-016-2720-z

Recent evidence supports the existence of a downstream autumn-migratory phenotype in juvenile anadromous brown trout (Salmo trutta), however the precise timing, extent and ecological significance of such behaviour remains ambiguous. We investigated t... Read More about Investigating the phenology of seaward migration of juvenile brown trout (Salmo trutta) in two European populations.

Evaluating the effectiveness of a Larinier super active baffle fish pass for European river lamprey Lampetra fluviatilis before and after modification with wall-mounted studded tiles (2016)
Journal Article
Tummers, J., Winter, E., Silva, S., O'Brien, P., Jang, M., & Lucas, M. (2016). Evaluating the effectiveness of a Larinier super active baffle fish pass for European river lamprey Lampetra fluviatilis before and after modification with wall-mounted studded tiles. Ecological Engineering, 91, 183-194. https://doi.org/10.1016/j.ecoleng.2016.02.046

To help achieve effective longitudinal river connectivity, evaluation of the efficacy of fishway use by upstream-migrating fishes is needed. Larinier super active baffle (SAB) fishways are relatively cheap retrofit fish passes, suitable for low-head...
