Emerging fungal pathogens have substantial consequences for infected hosts, as revealed by the global decline of amphibian species from the chytrid fungus. According to the curse of the Pharaoh hypothesis, free-living infectious stages typical of fungal pathogens lengthen the timespan of transmission. Free-living infectious stages whose lifespan exceeds the infection time of their hosts are not constrained by virulence, enabling them to persist at high levels and continue transmitting to further sensitive hosts. Using the only Mesomycetozoea fungal species that can be cultured, Sphaerothecum destruens, we obtained tractable data on infectivity and pathogen life cycle for the first time. Here, based on the outcomes of a set of infectious trials and combined with an epidemiological model, we show a high level of dependence on direct transmission in crowded, confined environments and establish that incubation rate and length of infection dictate the epidemic dynamics of fungal disease. The spread of Mesomycetozoea in the wild raise ecological concerns for a range of susceptible species including birds, amphibians and mammals. Our results shed light on the risks associated with farming conditions and highlight the additional risk posed by invasive species that are highly abundant and can act as infectious reservoir hosts.

Contemporary perspectives on the ecological impacts of invasive freshwater fishes

John Robert Britton

Summary: Introductions of non-native freshwater fish are increasing globally, but only a small proportion result in invasions. These invasive populations can have ecological impacts through various processes, some of which are harmful enough to be considered contributors to ecosystem collapse.

Preventing and controlling nonnative species invasions to bend the curve of global freshwater biodiversity loss

J. Robert Britton, Abigail J. Lynch, Helge Bardal, Stephanie J. Bradbeer, Julie A. Coetzee, Neil E. Coughlan, Tatenda Dalu, Elena Tricarico, Belinda Gallardo, Mark Lintermans, Frances Lucy, Chunlong Liu, Julian D. Olden, Rajeev Raghavan, Eleri G. Pritchard

Summary: The Emergency Recovery Plan for freshwater biodiversity recognizes that addressing nonnative species is one of the key actions to prevent loss of freshwater biodiversity. The plan emphasizes the importance of preventing introductions of nonnative species, but also highlights the need for early detection and rapid reaction measures in case of introduction. Control and containment measures are recommended for invasive species, along with invasion risk assessment and species-specific eradication methods.

Behavioural thermoregulation in cold-water freshwater fish: Innate resilience to climate warming?

Fatima Amat-Trigo, Demetra Andreou, Phillipa K. Gillingham, J. Robert Britton

Summary: Behavioural thermoregulation allows freshwater fish to adapt to different temperature environments, especially in extreme thermal conditions. Fish of different species and spatial scales move in response to temperature changes, with age and migratory ability affecting their tolerance to temperature differences. Research has primarily focused on studying the behavior of cold-water salmonids during summer, leaving a need for further study on the thermoregulatory behaviors of other non-salmonid fishes in warming conditions.

Summary: Biological invasions are a significant component of global change, but they can also have negative impacts on native populations. Efficient management policies are needed to prevent the spread of invasive species in non-native areas while protecting native populations. Genetic variation analysis can help assess the genetic state, identify invasion pathways, determine management strategies, and identify populations requiring conservation measures.

Parasite infection but not chronic microplastic exposure reduces the feeding rate in a freshwater fish

Ben Parker, J. Robert Britton, Iain D. Green, Fatima Amat-Trigo, Demetra Andreou

Summary: Microplastics are an environmental contaminant that can negatively affect aquatic biota. This study investigated the interaction between microplastic exposure and parasite infection on the freshwater fish Squalius cephalus. Contrary to predictions, microplastic exposure did not affect parasite abundance, but parasite infection led to lower feeding rates. The results suggest that the effects of parasitism are stronger than microplastic exposure, and the impact of microplastics may be relatively minor compared to other stressors.

Seascape genomics reveals limited dispersal and suggests spatially varying selection among European populations of sea lamprey (Petromyzon marinus)

Miguel Baltazar-Soares, J. Robert Britton, Adrian Pinder, Andrew J. Harrison, Andrew D. Nunn, Bernardo R. Quintella, Catarina S. Mateus, Jonathan D. Bolland, Jamie R. Dodd, Pedro R. Almeida, Victoria Dominguez Almela, Demetra Andreou

Summary: This study provided the first genome-wide characterization of genetic diversity in the European range of sea lamprey. It revealed a single metapopulation that includes freshwater spawning sites within the North Eastern Atlantic and the North Sea, with some limitations to dispersal at northern latitudes. The study also found that oxygen concentration and river runoffs impose spatially varying selection pressures across their distribution range in the ocean.

Individual repeatability in the timing of river entry indicates the strong influence of photoperiod in the spawning migrations of iteroparous twaite shad Alosa fallax

Mark I. A. Yeldham, J. Robert Britton, Charles Crundwell, Peter Davies, Jamie R. Dodd, Andrew D. Nunn, Randolph Velterop, Jonathan D. Bolland

Summary: The timing of entry into freshwater by mature anadromous fishes is determined by migration cues, particularly photoperiod, and shows high individual repeatability. This study used passive acoustic telemetry to track 71 twaite shad returning to the River Severn's upper estuary over multiple spawning seasons, and found that the timing of river entry was consistent between years and strongly predicted by increasing day length. Water temperatures and flow rates, however, were weak predictors and highly variable between years. The results highlight the importance of understanding migration cues and their variability in assessing the migration phenology of anadromous species.

Freire, Casper Gundelund, Kieran Hyder, Ivan Jaric, Robert Lennox, Wolf-Christian Lewin, Abigail J. Lynch, Stephen R. Midway, Warren M. Potts, Karina L. Ryan, Christian Skov, Harry V. Strehlow, Sean R. Tracey, Jun-ichi Tsuboi, Paul A. Venturelli, Jessica L. Weir, Marc Simon Weltersbach, Steven J. Cooke

Summary: The global COVID-19 pandemic led to restrictions on people's movements in many jurisdictions, affecting recreational angling. After the restrictions were lifted, initial surveys suggested increased participation and altered angler demographics, but evidence remained limited. This study examines changes in angling interest, licence sales, and angling effort in different regions during the 'pre-pandemic,' 'acute pandemic,' and 'COVID-acclimated' periods. It suggests that efforts to retain younger anglers and provide more urban angling opportunities could increase overall participation levels and enhance resilience in recreational fisheries.

A review and meta-analysis of the environmental biology of bleak Alburnus alburnus in its native and introduced ranges, with reflections on its invasiveness

Dani Latorre, Guillem Maso, Carlos Cano-Barbacil, Jose M. Zamora-Marin, David Almeida, Lorenzo Vilizzi, J. Robert Britton, Alejandra Cruz, Carlos Fernandez-Delgado, Anni G. Gonzalez-Rojas, Rafael Miranda, Francesc Rubio-Gracia, Ali Serhan Tarkan, Mar Torralva, Anna Vila-Gispert, Gordon H. Copp, Filipe Ribeiro

Summary: The bleak Alburnus alburnus is a medium-sized leuciscid fish that is naturally distributed across central European and western Asian fresh waters. It has been widely introduced in Europe and northern Africa as a forage species for game fishes. In its native range, it feeds mainly on zooplankton, but non-native populations show high phenotypic plasticity in their biological attributes, adapting to local environmental conditions and invading different ecosystems. This plasticity, coupled with broad physiological tolerance, is likely to facilitate its adaptation and invasion of new habitats in the future.

Promoting the use of non-lethal sample collection for analysing the trophic relationships of inshore flatfish populations using stable isotope analysis

Irmak Kurtul, Ali Serhan Tarkan, J. Robert Britton

Summary: Non-lethal sampling methods can be used for trophic studies on inshore flatfish populations of high value. Fin tissue and epidermal mucus can serve as alternatives to muscle for stable isotope analysis. Differences in isotopic values can be predicted and converted using linear regression. These tissue alternatives allow for non-lethal sampling and analysis of flatfish populations.

Trophic relationships of translocated and indigenous chub Squalius cephalus populations with trophically analogous fishes

Bertram I. C. Warren, Adrian C. Pinder, Ben Parker, A. Serhan Tarkan, J. Robert Britton

Summary: This study assessed the trophic ecology of a translocated chub population using stable isotope metrics and compared it with native chub populations. The results suggest that the colonization of lowland rivers by translocated chub is facilitated by their isotopic relationships with other fishes similar to those observed in their native range.
