Downstream passage of silver European eel (Anguilla anguilla) at a pumping station with a gravity sluice (2020)
Journal Article
Baker, N. J., Wright, R. M., Cowx, I. G., Murphy, L. A., & Bolland, J. D. (2020). Downstream passage of silver European eel (Anguilla anguilla) at a pumping station with a gravity sluice. Ecological engineering, Article 106069. https://doi.org/10.1016/j.ecoleng.2020.106069

The European eel (Anguilla anguilla (L.)) is critically endangered after a multi-decadal decline. Anthropogenic disruption to downstream migration, including at water control structures such as pumping stations, is thought to be one of the contributi...

Evaluating the impact of hydropower on downstream migrating anguillid eels: Catchment-wide and fine-scale approaches to identify cost-effective solutions (2020)
Journal Article
Baker, N. J., Boubée, J., Lokman, P. M., & Bolland, J. D. (2020). Evaluating the impact of hydropower on downstream migrating anguillid eels: Catchment-wide and fine-scale approaches to identify cost-effective solutions. The Science of the total environment, 748, Article 141111. https://doi.org/10.1016/j.scitotenv.2020.141111

Hydropower is an increasingly popular source of renewable and ‘green’ (in terms of emissions) energy, but reduced longitudinal connectivity and diverting flow through turbines can have negative impacts on catadromous anguillid eel species that have d...

Novel insights into the marine phase and river fidelity of anadromous twaite shad Alosa fallax in the UK and Ireland (2020)
Journal Article
Davies, P., Britton, R. J., Nunn, A. D., Dodd, J. R., Crundwell, C., Velterop, R., Ó’Maoiléidigh, N., O’Neill, R., Sheehan, E., Stamp, T., & Bolland, J. (2020). Novel insights into the marine phase and river fidelity of anadromous twaite shad Alosa fallax in the UK and Ireland. Aquatic conservation : marine and freshwater ecosystems, 30(7), 1291-1298. https://doi.org/10.1002/aqc.3343

© 2020 The Authors. Most research on anadromous fishes has been invested in their freshwater life-phases, resulting in a relatively sparse understanding of their spatial ecology during marine life-phases. However, understanding the marine dispersal... Read More about Novel insights into the marine phase and river fidelity of anadromous twaite shad Alosa fallax in the UK and Ireland.

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...

Water Resources Research, 56(6), Article e2018WR024196. https://doi.org/10.1029/2018WR024196

Natural hydrological regimes encompass varying seasonal flow characteristics that provide fish with cues and opportunities for upstream spawning migrations, but these flows are often modified/absent in regulated rivers. Compensatory artificial flows... Read More about The Response of River-Resident Fish to Reservoir Freshet Releases of Varying Profiles Intended to Facilitate a Spawning Migration.
