“…Therefore, their current distributions are also much influenced by their introduction histories and basin boundaries. Nevertheless, SDMs constitute a valuable tool to identify those regions which are particularly vulnerable to the establishment of invasive alien species (Perrin et al, 2021). Although Darlington's classification has received some criticism (Rosen, 1974;Sparks & Smith, 2005), it is widely applied and well related to experimental seawater tolerance (see Appendix S1).…”

Aim: Unravelling the ecological and historical factors that underlie species distributions has challenged ecologists for a long time. Thus, our objective is to understand the role of environmental variables explaining the distribution of three major ecoevolutionary groups of inland fishes (Darlington's divisions: primary, i.e. strict freshwater; secondary, i.e. salt-tolerant; and peripheral, i.e. diadromous and marine origin), and how these variables are related to fish traits.Location: Iberian Peninsula.Taxon: 51 native and 17 alien inland fish species from the Iberian Peninsula. Methods:We modelled distributions of the most common inland fish species across the Iberian Peninsula to compare the importance of different predictors among the three Darlington's divisions and between native and alien species. To explore the importance of specific environmental variables in determining the distribution of different traits of inland fish, variable importances obtained from species distribution models were subjected to a redundancy analysis.Results: Darlington's divisions differ significantly in salinity tolerance, in distribution overlap, in the importance of distribution predictors and associated life-history traits. Topographic and climatic variables were generally more important than land use and anthropogenic factors in explaining fish distributions. We found significant differences in the importance of variables explaining the distribution of native vs. alien species and especially among Darlington's divisions. River basin was most important for primary native and many alien species. Increasing mean temperature and damming were positively associated with the presence of tolerant, large-bodied and warm-water alien species from more hydrologically stable habitats.Main conclusions: Despite marked differences in the distribution patterns of native and alien species, evolutionary and introduction histories as well as seawater tolerance are central factors explaining the current distribution of inland fishes. Darlington's divisions proved useful for addressing ecological and biogeographical questions at broader spatial scales.

“…The listing of roach as a species with potentially high ecological impact when translocated to new locations has seemingly not led to more studies. However, in 2021 a new study trying to forecast the distribution of roach was published (Perrin et al 2021). This study also discussed several other species that are considered as regionally invasive.…”

A paradoxical bias in knowledge about Norwegian freshwater fishes: research efforts during 1980-2020

Norwegian freshwater systems are in general species poor. That is particularly the case for the freshwater fishes. Only 32 species are considered native, whereas an additional 12 species are non-native. Some of the non-native species are also considered to be invasive and have negative ecosystem effects. Freshwater fishes are exposed to numerous stressors through their life cycle, many of which are of anthropogenic origin. In order to manage and conserve the diversity of fish there is a need for basic knowledge and understanding. Here I make an effort to review the published research on all Norwegian freshwater fish species during the 1980-2020 period, based on a standardized search on the Web of Science. Over 2000 relevant articles were retrieved and evaluated following the search. The research activity has been highly biased, with most research activity directed at a few species of high economic and societal value. Most work was directed at Atlantic salmon Salmo salar and brown trout S. trutta, and in general towards species within the salmonid family. Extremely little attention was directed at species such as the lampreys (four species) and sculpins (three species). Also, many species that has been listed on the Norwegian Red List during various time periods has not been given any particular attention. This lack of attention was also evident for most of the non-native species. The strong bias in research activity and lack of attention given to many species will clearly lead to difficulties in making appropriate management decisions. This is unfortunate, in particular in a time when climate change may lead to numerous ecosystem level changes.

“…Areas with strong topographical variation could provide dispersal barriers for novel species, and subsequently provide refugia for species likely to be outcompeted (Perrin et al, 2020). However such refugia are only likely to be tenable if human translocation is sufficiently regulated so as to prevent the introduction of novel species (Hesthagen & Sandlund, 2004;Perrin et al, 2021). As such, models like the one constructed here could enable researchers not only to identify environmental covariates which may drive changes in species associations and subsequently identify areas where native species are vulnerable to local extinctions, but also to identify areas where such species are likely to persist.…”

Due to global trends in species distribution range shifts and biodiversity loss, ecosystems worldwide are likely to undergo considerable changes in community composition (Jennings & Harris, 2017;Seebens et al., 2020). Along with the increased spread of nonnative species as a result of globalisation, increasing average temperatures due to climate change will enable new species to make their way into environments previously too cold for them to either
