Journal Article
Evans, O. J., Norman, J., Carter, L. J., Hutchinson, T., Don, A., Wright, R. M., Tuhtan, J. A., Toming, G., & Bolland, J. D. (2024). Rethinking fish-friendliness of pumps by shifting focus to both safe and timely fish passage for effective conservation. Scientific reports, 14(1), Article 17888. https://doi.org/10.1038/s41598-024-67870-5

Globally, catadromous freshwater eels of the genus Anguilla are of conservation concern, including critically endangered European eel (Anguilla anguilla). Pumping stations that move river water to a higher elevation severely impact eels during their...

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...

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...

The impact of extreme flood-relief pump operations on resident fish in an artificial drain and the potential for artificial habitat introduction (2023)
Journal Article
Norman, J., Reeds, J., Wright, R. M., & Bolland, J. D. (in press). The impact of extreme flood-relief pump operations on resident fish in an artificial drain and the potential for artificial habitat introduction. Fisheries Management and Ecology, https://doi.org/10.1111/fme.12636

Fish are ubiquitous in pumped artificial drains but channel maintenance exposes fish to high flows and predators, and fish communities may experience population-level threats if they are unable to access refuge during extreme flood-relief pump operat...

The influence of passive wedge-wire screen aperture and flow velocity on juvenile European eel exclusion, impingement and passage (2023)
Journal Article
Carter, L. J., Collier, S. J., Thomas, R. E., Norman, J., Wright, R. M., & Bolland, J. D. (2023). The influence of passive wedge-wire screen aperture and flow velocity on juvenile European eel exclusion, impingement and passage. Ecological engineering, 192, Article 106972. https://doi.org/10.1016/j.ecoleng.2023.106972

The European eel (Anguilla anguilla) is a critically endangered catadromous fish. The decline has partly been attributed to water management infrastructure that abstract water from rivers for potable and industrial water supply, irrigation, hydroelec...

Understanding the temporal dynamics of a lowland river fish community at a hazardous intake and floodgate to inform safe operation (2023)
Journal Article
Norman, J., Wright, R. M., Don, A., & Bolland, J. D. (2023). Understanding the temporal dynamics of a lowland river fish community at a hazardous intake and floodgate to inform safe operation. Journal of environmental management, 336, Article 117716. https://doi.org/10.1016/j.jenvman.2023.117716

Entrainment and mortality of freshwater fish at hazardous pumping station intakes used for Flood Risk Management (FRM) are of global concern. Although upstream and downstream passage of diadromous fish has received considerable attention, the ecologi...

Understanding behavioural ecology of river-resident fish in winter to improve protection at water pumping stations (2022)
Thesis
Norman, J. Understanding behavioural ecology of river-resident fish in winter to improve protection at water pumping stations. (Thesis). University of Hull. https://hull-repository.worktribe.com/output/4291429

Globally, there is a reliance on water pumping stations to manage river levels and prevent flooding in heavily-modified anthropogenic rivers. Pumping stations damage longitudinal and lateral river connectivity and their operation presents a major ris...

Understanding temporal variability in fish and eel movements to minimise the likelihood of entrainment at water pumping stations (2019)
Thesis
Norman, J. Understanding temporal variability in fish and eel movements to minimise the likelihood of entrainment at water pumping stations. (Thesis). University of Hull. https://hull-repository.worktribe.com/output/4222522

Rivers in the United Kingdom have been subject to extensive modification to meet societal demands for navigation, drinking water, industry, hydropower, drainage, and abstraction. This heavy pressure on river resources has resulted in many constrained...
