Conservation of fish communities: Extending the ‘research life cycle’ by achieving practical effects

Abstract

This article highlights the practical impact of our 2018 Aquatic Conservation: Marine and Freshwater Ecosystems publication, ‘Importance of peripheral basins: Implications for the conservation of fish assemblages’, which described fish communities in a Polish river. Data on the fish assemblages of the Dniester River (Black Sea basin) are scarce; however, evidence indicates that the assemblages have declined. In our 2018 study, we hypothesized that the peripheral basin (the small basin on the edge) of the larger Upper Dniester River basin (the Strwiąż River) could maintain good ecological status and contained unique fish assemblages. To examine the influence of historical factors and assess the role of peripheral basins on fish conservation, data from the Strwiąż basin were compared with the adjacent but unconnected Wiar basin (the Vistula basin; Baltic Sea basin). The Strwiąż River fish assemblages featured higher species richness and a greater number of native Ponto–Caspian species that function near the edge of their ranges. This article focuses on four impacts of the 2018 publication: increasing awareness by various groups and organizations of the unique character of the surveyed river basin; highlighting important issues in assessing the ecological status of European rivers; driving the red‐listing of species and the development of stream fish conservation strategies; and identifying possible future impacts. Our 2018 publication demonstrated the value of studying peripheral basins, which may affect conservation strategy development and encourage study of the importance of other peripheral basins and their role in aquatic resources conservation. Our article influenced the interpretation of fish‐based biotic indices and the conduct of monitoring work and its evaluation. It also strongly emphasized the native origin of the racer goby (Babka gymnotrachelus) in the Strwiąż River, which was important for subsequent works seeking to change the legal status of the species in Poland.

More exposure opportunities for promoting freshwater conservation

“…Moreover, active engagement in follow-up monitoring and assessment programmes (e.g. LIFE programmes and Red List assessments) with related authorities after publication can also help to ensure the implementation of recommendations from scientific studies (Abeli et al, 2020;Bylak & Kukuła, 2020). Given the multiple, potential drivers behind conservation efforts, future studies need to disentangle the effect of different factors on attention received by publications from society, as well as the influence of scientific publications on conservation practice (Table 2).…”

“…Populations at the periphery of a distribution constitute interesting case studies for conservation (e.g., Bylak and Kukuła 2018 , 2020 ). Compared to populations at the core of the distribution range, peripheral populations may be adapted to different selective pressures and, thus, hold important evolutionary potential in a rapidly changing environment (Channell and Lomolino 2000 ; Channell 2004 ).…”

“…Furthermore, the assessment methods based on fish population (Bylak and Kukuła, 2020) and vegetation population (Behn et al, 2018;Dybiec et al, 2020) were widely used to evaluate the health of BCEs. Although the methods could provide valuable information about the health status of BCEs, they may not capture the full complexity of ecotone dynamics and processes.…”
