Journal Article
Dodd, J. R., Noble, R. A., Nunn, A. D., Owen, H. M., Moccetti, P., Harvey, J. P., Wallace, L., Gillespie, B., Joyce, D. A., & Bolland, J. D. (online). Spatial ecology and population dynamics of brown trout Salmo trutta L. in reservoirs and headwater tributaries. Journal of fish biology, https://doi.org/10.1111/jfb.15814

This investigation compared the spatial ecology and population dynamics of brown trout Salmo trutta L. between reservoirs with (impact; Langsett Reservoir) and without (control; Grimwith Reservoir) barriers to fish movements into headwater tributarie...

Genetic consequences of improved river connectivity in brown trout (Salmo trutta L.) (2024)
Journal Article
Moccetti, P., Dodd, J. R., Joyce, D. A., Nunn, A. D., Gillespie, B., & Bolland, J. D. (2024). Genetic consequences of improved river connectivity in brown trout (Salmo trutta L.). Evolutionary Applications, 17(4), Article e13660. https://doi.org/10.1111/eva.13660

Fragmentation of watercourses poses a significant threat to biodiversity, particularly for migratory fish species. Mitigation measures such as fishways, have been increasingly implemented to restore river connectivity and support fish migration. The...

Tracking repeat spawning anadromous fish migrations over multiple years in a fragmented river suggests philopatry and sex-linked variation in space use (2024)
Journal Article
Davies, P., Britton, J. R., Andreou, D., Crundwell, C., Dodd, J. R., Lepais, O., Nunn, A. D., Sabatino, S., Velterop, R., & Bolland, J. D. (2024). Tracking repeat spawning anadromous fish migrations over multiple years in a fragmented river suggests philopatry and sex-linked variation in space use. Aquatic sciences, 86(2), https://doi.org/10.1007/s00027-024-01048-z

There is limited knowledge of how philopatry influences the spatial ecology of iteroparous anadromous species during their spawning migrations, but this knowledge is important in understanding population responses to interventions such as river recon...

Emigration of post-spawned twaite shad Alosa fallax, an anadromous and iteroparous fish, in a highly fragmented river (2024)
Journal Article
Yeldham, M. I., Britton, J. R., Crundwell, C., Davies, P., Dodd, J. R., Nunn, A. D., …Bolland, J. D. (2024). Emigration of post-spawned twaite shad Alosa fallax, an anadromous and iteroparous fish, in a highly fragmented river. Journal of fish biology, https://doi.org/10.1111/jfb.15713

Anthropogenic barriers are widely known to negatively impact the spawning migrations of anadromous fishes, by delaying or preventing passage upstream. Although the impacts of barriers on emigrating post-spawned adults are less well studied, they coul...

Factors influencing European river lamprey passage at a tidal river barrier (2024)
Journal Article
Lothian, A. J., Bolland, J. D., Albright, A. J., Jubb, W. M., Bubb, D. H., Noble, R. A., Nunn, A. D., Dodd, J. R., Tummers, J. S., & Lucas, M. C. (2024). Factors influencing European river lamprey passage at a tidal river barrier. Hydrobiologia, https://doi.org/10.1007/s10750-024-05633-z

Understanding and improving passage by diadromous species at tidal barriers is less well advanced than that for non-tidal anthropogenic river barriers. This study assessed factors affecting upstream passage of anadromous river lamprey (Lampetra fluvi... Read More about Factors influencing European river lamprey passage at a tidal river barrier.
