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...

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.

Extinction risks and threats facing the freshwater fishes of Britain (2023)
Journal Article
Nunn, A. D., Ainsworth, R. F., Walton, S., Bean, C. W., Hatton-Ellis, T. W., Brown, A., Evans, R., Atterborne, A., Ottewell, D., & Noble, R. A. (in press). Extinction risks and threats facing the freshwater fishes of Britain. Aquatic conservation : marine and freshwater ecosystems, https://doi.org/10.1002/aqc.4014

Extinctions occur naturally in all environments, but rates have accelerated rapidly during the Anthropocene, especially in fresh water. Despite supporting many fish species of conservation importance, there has never been a formal assessment of their...

Upstream spawning migration of river lamprey (Lampetra fluviatilis) in the River Yorkshire Ouse, 2018-2020 (2023)
Data
Bolland, J. D., Jubb, W. M., Noble, R. A. A., Nunn, A. D., Dodd, J. R., Lucas, M. C., Lothian, A. J., Bubb, D. H., & Albright, A. J. (2023). Upstream spawning migration of river lamprey (Lampetra fluviatilis) in the River Yorkshire Ouse, 2018-2020. [Data]. https://doi.org/10.14284/623

This study investigated the upstream spawning migration of anadromous river lamprey in the Yorkshire Ouse, a highly dendritic and heavily fragmented tributary of the Humber Estuary (home to one of the largest UK river lamprey populations). The main E... Read More about Upstream spawning migration of river lamprey (Lampetra fluviatilis) in the River Yorkshire Ouse, 2018-2020.

Catchment-wide interactive effects of anthropogenic structures and river levels on fish spawning migrations (2023)
Journal Article
Jubb, W. M., Noble, R. A., Dodd, J. R., Nunn, A. D., Schirrmacher, P., Lothian, A. J., Albright, A. J., Bubb, D. H., Lucas, M. C., & Bolland, J. D. (2023). Catchment-wide interactive effects of anthropogenic structures and river levels on fish spawning migrations. Anthropocene, 43, Article 100400. https://doi.org/10.1016/j.ancene.2023.100400

Worldwide, rivers are extensively fragmented by anthropogenic structures, reducing longitudinal connectivity, inhibiting migration and leading to severe declines in many fish populations, especially for diadromous species. However, few studies have d... Read More about Catchment-wide interactive effects of anthropogenic structures and river levels on fish spawning migrations.

Seascape genomics reveals limited dispersal and suggests spatially varying selection among European populations of sea lamprey (Petromyzon marinus) (2023)
Journal Article
Baltazar-Soares, M., Britton, J. R., Pinder, A., Harrison, A. J., Nunn, A. D., Quintella, B. R., Mateus, C. S., Bolland, J. D., Dodd, J. R., Almeida, P. R., Dominguez Almela, V., & Andreou, D. (2023). Seascape genomics reveals limited dispersal and suggests spatially varying selection among European populations of sea lamprey (Petromyzon marinus). Evolutionary Applications, 16(6), 1169-1183. https://doi.org/10.1111/eva.13561

Sea lamprey Petromyzon marinus is an anadromous and semelparous fish without homing behaviors. Despite being a freshwater, free-living organism for a large part of their life cycle, its adulthood is spent as a parasite of marine vertebrates. In their...
