Journal Article
Evans, O. J., Carter, L. J., Hutchinson, T., Don, A., Wright, R. M., Baktoft, H., Pauwels, I. S., & Bolland, J. D. (2024). Inter-annual variation in movements and passage of seaward migrating European eels at a shrouded Archimedean screw pumping station. Ecological engineering, 209, Article 107389. https://doi.org/10.1016/j.ecoleng.2024.107389

The construction of less damaging (here called fish-friendly) pumping stations has taken place in recent years, but it is unknown if they provide efficient and timely passage to migratory fish, such as European eel (Anguilla anguilla (L.)). The pump... Read More about Inter-annual variation in movements and passage of seaward migrating European eels at a shrouded Archimedean screw pumping station.

Ex situ experimentation to determine if introduced artificial habitat can provide alternative refuge to hazardous anthropogenic structures (2024)
Journal Article
Norman, J., Clark, D., Henshaw, A., Wright, R. M., Cattaneo, M. E. G. V., & Bolland, J. D. (2024). Ex situ experimentation to determine if introduced artificial habitat can provide alternative refuge to hazardous anthropogenic structures. Restoration Ecology, Article e14157. https://doi.org/10.1111/rec.14157

Highly degraded lowland river ecosystems are of global concern to restoration practitioners. Hazardous anthropogenic structures, such as those used for water level management (i.e. pumping stations), present a mortality risk to fish and associated ch...

Can't pass or won't pass: the importance of motivation when quantifying improved connectivity for riverine brown trout Salmo trutta (2023)
Journal Article
Dodd, J. R., Cowx, I. G., Joyce, D. A., & Bolland, J. D. (in press). Can't pass or won't pass: the importance of motivation when quantifying improved connectivity for riverine brown trout Salmo trutta. Journal of fish biology, https://doi.org/10.1111/jfb.15628

Reversing the negative impacts that anthropogenic habitat fragmentation has on animal movement is a key goal in the management of landscapes and conservation of species globally. Accurate assessment of measures to remediate habitat fragmentation, suc...

Impact of anthropogenic infrastructure on aquatic and avian predator–prey interactions in a modified lowland river (2023)
Journal Article
Norman, J., Reeds, J., Wright, R. M., & Bolland, J. D. (in press). Impact of anthropogenic infrastructure on aquatic and avian predator–prey interactions in a modified lowland river. Freshwater biology, https://doi.org/10.1111/fwb.14201

The relationship between aquatic and avian predators and prey is a fundamental process that influences the ecological dynamics of freshwater communities; a landscape of fear underpins spatial and temporal habitat use of prey, i.e., non-consumptive pr...

Dynamic competition and resource partitioning during the early life of two widespread, abundant and ecologically similar fishes (2020)
Journal Article
Nunn, A. D., Vickers, L., Mazik, K., Bolland, J., Peirson, G., Axford, S., Henshaw, A., & Cowx, I. G. (2020). Dynamic competition and resource partitioning during the early life of two widespread, abundant and ecologically similar fishes. Hydrobiologia, 847, 2211-2224. https://doi.org/10.1007/s10750-020-04247-5

Competition and resource partitioning can have profound implications for individuals, populations and communities, and thus food webs, ecosystems and the management of biota and environments. In many species, the impacts of competition and resource p...

Upstream passage of adult sea trout (Salmo trutta) at a low-head weir with an Archimedean screw hydropower turbine and co-located fish pass (2018)
Journal Article
Dodd, J. R., Bolland, J. D., Hateley, J., Cowx, I. G., Walton, S. E., Cattaneo, M. E. G. V., & Noble, R. A. A. (2018). Upstream passage of adult sea trout (Salmo trutta) at a low-head weir with an Archimedean screw hydropower turbine and co-located fish pass. Marine and Freshwater Research, 69(12), 1822-1833. https://doi.org/10.1071/MF18125

© 2018 CSIRO. The exploitation of riverine systems for renewable energy has resulted in large numbers of small-scale hydropower schemes on low-head weirs. Although considered a clean and 'green' energy source in terms of emissions, hydropower can aff...

Win, win, win: Low cost baffle fish pass provides improved passage efficiency, reduced passage time and broadened passage flows over a low-head weir (2018)
Journal Article
Dodd, J. R., Cowx, I. G., & Bolland, J. D. (2018). Win, win, win: Low cost baffle fish pass provides improved passage efficiency, reduced passage time and broadened passage flows over a low-head weir. Ecological engineering, 120(September 2018), 68-75. https://doi.org/10.1016/j.ecoleng.2018.05.028

The number of low-head barriers to fish migration far outweighs the number of large magnitude barriers and thus the cumulative negative impact on fish communities could also be far greater. Removal of man-made obstructions to fish migration is the mo...
