<jats:p>The validity of four gudgeon species known for the ichthyofauna of North Macedonia has been a matter of different taxonomic disputes (except for <jats:italic>Gobio ohridanus</jats:italic> Karaman, 1924). Recently, a restoration of the species status was proposed for <jats:italic>Gobio balcanicus</jats:italic> Dimovski et Grupče, 1977 and <jats:italic>Romanogobio banarescui</jats:italic> (Dimovski et Grupče, 1974). So far, <jats:italic>Romanogobio stankoi</jats:italic> (Karaman, 1974), has not been a part of any recent investigation and it is still considered as a junior synonym of <jats:italic>Romanogobio elimeius</jats:italic> (Kattoulas, Stephanidis et Economidis, 1973) or <jats:italic>R. banarescui</jats:italic> due to the lack of distinctive morphological characters. The osteological characters in the structure of the vertebral column, have significance to the systematics of the gudgeons, especially in elevation of <jats:italic>Romanogobio</jats:italic> at the level of genus. To contribute to resolving the taxonomic status in these gudgeon species, the goal of this paper is to identify distinctive characters by presenting and analyzing the structure of their vertebral column. Samples were inspected from the fish collections in the Institute of Biology (<jats:italic>G. ohridanus</jats:italic>), the Institute of Animal Science (<jats:italic>G. balcanicus</jats:italic>), and the Macedonian Museum of Natural History (both <jats:italic>Romanogobio</jats:italic> species). Fish samples were X-rayed as well as cleared and double-stained. Obtained data on the number of vertebrae were presented through the vertebral formula following Naseka (1996). Multiple Correspondence Analysis (MCA) was used to check the interrelation between taxa and the number of vertebrae in all units of the vertebral column. <jats:italic>G. balcanicus</jats:italic> is distinguished from <jats:italic>G. ohridanus</jats:italic> mainly in the predorsal and preanal subregion (10 vs. 11 vertebrae and 1 vs. 0 vertebrae, respectively), while <jats:italic>R. stankoi</jats:italic> distinguishes from <jats:italic>R. banarescui</jats:italic> by the number of vertebrae in the preanal and postanal subregion (2 vs. 4 vertebrae and 19 vs. 17 vertebrae, respectively).

This study presents the findings from three seasonal field surveys conducted in the Lepenc River and its tributaries during 2023. The surveys were carried out on May, July, and October, focusing on six sampling sites: Prevallë, Lepenc (Kaçanik), Hani i Elezit, Jezerc, Gerlicë, and Nerodime (Kaçanik). Standardized electrofishing technique was applied, in accordance with the methods used by the European Union Water Framework Directive (EU WFD) monitoring protocols, which have been implemented in many Balkan regions. A total of 790 fish specimens were caught, identified, measured, and subsequently released back into their natural habitats. The species found during this investigation were: Salmo sp., Barbus balcanicus, Squalius varedaresnisi, Alburnoides thessalicus, Alburnus thessalicus, Gobio balcanicus, Phoxinus sp., and Oxynoemacheilus bureschi. The sampling site in Gerlicë consistently showed no presence of fish, likely due to pollution. The findings provide a comprehensive overview of fish community composition and their seasonal variations, highlighting the influence of physicochemical parameters on aquatic biodiversity. The results emphasize the urgent need for conservation measures to address habitat degradation and pollution, ensuring the preservation and restoration of biodiversity in the Lepenc River Basin.

Challenges to preserving native brown trout diversity in the Western Balkans

In the Western Balkans, fishery management and legislation do not recognize the high molecular diversity of native brown trout. For this reason, stocking of streams relies on brown trout of non-native origin. In recent years, there have been new findings about the life-history features, dispersal and molecular characterisation of nominal taxa of brown trout in the Western Balkans. This has prompted to a re-evaluation of their risk of invasiveness in the region. In this study, based on a screening of six non-native lineages of brown trout, four lineages were ranked as high risk and two as medium risk of invasiveness under current climate conditions, whereas one lineage was ranked as high risk and the other five as medium risk under predicted global warming scenarios. Variation in scores and risk outcomes were related to life-history traits differing among lineages, with most pronounced differences in dispersal mechanisms. The results of this study point to the need for improvement of relevant legislation in several sectors of fishery management. Management strategies should aim to mitigate the conflicts arising among stakeholders, which contribute to the deterioration of the native traits of brown trout stocks throughout the Western Balkans.

A global-scale screening of non-native aquatic organisms to identify potentially invasive species under current and future climate conditions

The threat posed by invasive non-native species worldwide requires a global approach to identify which introduced species are likely to pose an elevated risk of impact to native species and ecosystems. To inform policy, stakeholders and management decisions on global threats to aquatic ecosystems, 195 assessors representing 120 risk assessment areas across all six inhabited continents screened 819 non-native species from 15 groups of aquatic organisms (freshwater, brackish, marine plants and animals) using the Aquatic Species Invasiveness Screening Kit. This multi-lingual decision-support tool for the risk screening of aquatic organisms provides assessors with risk scores for a species under current and future climate change conditions that, following a statistically based calibration, permits the accurate classification of species into high-, medium- and low-risk categories under current and predicted climate conditions. The 1730 screenings undertaken encompassed wide geographical areas (regions, political entities, parts thereof, water bodies, river basins, lake drainage basins, and marine regions), which permitted thresholds to be identified for almost all aquatic organismal groups screened as well as for tropical, temperate and continental climate classes, and for tropical and temperate marine ecoregions. In total, 33 species were identified as posing a 'very high risk' of being or becoming invasive, and the scores of several of these species under current climate increased under future climate conditions, primarily due to their wide thermal tolerances. The risk thresholds determined for taxonomic groups and climate zones provide a basis against which area-specific or climate-based calibrated thresholds may be interpreted. In turn, the risk rankings help decision-makers identify which species require an immediate 'rapid' management action (e.g. eradication, control) to avoid or mitigate adverse impacts, which require a full risk assessment, and which are to be restricted or banned with regard to importation and/or sale as ornamental or aquarium/fishery enhancement.

Speaking their language – Development of a multilingual decision-support tool for communicating invasive species risks to decision makers and stakeholders

Environmental changes due to non-native species introductions and translocations are a global concern. Whilst understanding the causes of bioinvasions is important, there is need for decision-support tools that facilitate effective communication of the potential risks of invasive non-native species to stakeholders. Decision-support tools have been developed mostly in English language only, which increases linguistic uncertainty associated with risk assessments undertaken by assessors not of English mother tongue and who need to communicate outcomes to local stakeholders. To reduce language-based uncertainty, the 􏰢ecology-of-language’ paradigm was applied when developing the Aquatic Species Invasiveness Screening Kit 􏱜AS-ISK􏰛, a decision-support tool that offers 􏱘􏳏 languages in which to carry out screenings and communicate outcomes to stakeholders. Topics dis- cussed include uncertainty related to language-specific issues encountered during the AS-ISK translation and the potential benefits of a multilingual decision-support tool for reducing linguistic uncertainty and enhancing communication between scientists, environmental managers, and policy and decision makers.
