Special Issue Information

Dear Colleagues,

We are proud to celebrate the 15th anniversary of Diversity, originally published back in 2009. To mark this occasion, a Special Issue dedicated to the field of “Freshwater Biodiversity Hotspots in 2024” is in production.

In the ever-changing landscape of global biodiversity, freshwater ecosystems stand out as critical hotspots of species richness and ecological diversity. From the majestic rivers of the Amazon to the pristine lakes of the Arctic, freshwater habitats are under increasing pressure from human activities and environmental changes and it is vital, therefore, that these ecosystems and their biodiversity are preserved.

We invite researchers to contribute papers that investigate the mechanisms driving species and genetic diversity and distribution patterns in freshwater habitats, shedding light on the complex interplay between biotic and abiotic factors. Additionally, research that evaluates the impacts of anthropogenic disturbances on freshwater biodiversity and explores innovative approaches to the monitoring, conservation, and restoration of freshwater biodiversity are also welcome. Experts in the field are invited to submit high-quality papers to this Special Issue and the topics of interest may include, but are not limited to, the following:

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Fish geographical distribution has pivotal importance in management/conservation policies, especially for community interest species, requiring careful protection measures. However, distribution areas could be difficult to define if the taxonomy has only recently been resolved, and particular attention must be paid where co-generic species share their ranges. Our work reports new insights about the distribution of T. muticellus and T. souffia in Northeastern Italy, where their geographical ranges overlap, and these native species share a cross-border area. Fish samplings and meristic and genetical investigations were performed, and our results showed that T. muticellus seems to expand its range east due to human-induced translocations, while T. souffia occurs only in the cross-border hydrological networks between Italy and Slovenia. Telestes genetic characterization for the Tagliamento River Basin and Northeastern Italy lowland is reported, improving the genus distribution dataset in the Po Plain watershed, where T. muticellus is endemic. The main meristic feature to discriminate the species was the number of lateral line scales, explaining 44.5% of the dissimilarity among the analyzed populations. Findings about the distribution of the investigated populations highlight the critical need for targeted conservation strategies in biodiversity hotspots, where overlapping species distributions, such as T. muticellus and T. souffia, play a vital role in preserving regional biodiversity.

Hoefkenia hunsrueckensis, a New Genus and Species from Europe, and the Identity of Virescentia vogesiaca (F.W.Schultz ex Skuja) Necchi, D.C.Agostinho & M.L.Vis (Batrachospermales, Rhodophyta)

Freshwater red algae from Hunsrück-Hochwald National Park previously identified as Virescentia vogesiaca are described as Hoefkenia hunsrueckensis gen. et sp. nov. They cluster in the phylogenetic tree together with Kumanoa and form its sister clade. Virescentia is rendered monophyletic by exclusion of these samples. The taxonomic history of Virescentia vogesiaca is described. The species was named by Skuja referring to the description of Batrachospermum vagum var. flagelliforme Sirodot and the specimens all come from Western France and Spain. The name Batrachospermum vogesiacum was erroneously applied referring to a specimen from the North Vosges close to Germany collected and annotated by F.W. Schultz and representing the new Hoefkenia hunsrueckensis. However, this specimen was never cited in the protologue of Virescentia vogesiaca. We provide evidence that the real Virescentia vogesiaca is endemic to Western France and Spain, and that Hoefkenia hunsrueckensis is restricted to Eastern Belgium, Eastern France and SW Germany, differing in morphological and molecular characters.

Diamond and oil and gas production carries risks to the aquatic ecosystem. In Eastern Siberia, on the territory of the Central Yakut Plain, mining development of the Yakut diamond-bearing province and Tas-Yuryakh oil and gas condensate field has been underway for several decades. But the problem of studying negative consequences in the region is covered only from the point of view of the impact on terrestrial ecosystems. The purpose of this study was to assess the impact of diamond and oil and gas production on the aquatic ecosystems of the region using the bioindicative properties of diatoms. The work used previously widely tested methods of ecological mapping, JASP, and species–environments relationship analysis. The results of chemical analysis of water showed that in oil and gas production areas, there is no pollution with petroleum products, but the concentration of silicon and zinc is increased. The study identified key pollutants in the Central Yakut Plain and demonstrated the effectiveness of diatoms as bioindicators. Elevated chloride levels were found in diamond mining areas, and increased copper levels were noted in oil production regions. In the diatom flora of the region, 144 species were identified, of which 137 are indicator species. Natural and anthropogenic clusters of environmental factors are identified, characterized by a specific effect on the species composition and taxonomic structure of diatom communities. The results obtained are suitable for assessing the level of anthropogenic impact on aquatic communities of photosynthetic microorganisms in permafrost conditions. Full article
