As Alexander Stephanides fished, the Spercius River was known to be important for biodiversity. Crossroads between the dry and biogeographically isolated western basins and the geographically rich northern (Macedonia-Thessaly ecoregion). Stephanides described a "subspecies" of spirulina from here and nearby (albernoides spp. were called thessalicus ). He did not see gender differences between the two river fish - the gender differences between them are very small (published in 1950...). What he didn't know then was that these same fish were very different... genetically.
Despite the very similar opinions, when compared to other European spirulina species, Spercheios spirlines are genetically different from other spirulina species. The genetic difference from other Spirulina species is 7.3 to 8.8% (based on cytochrome b nucleotide sequences). Visible difference.
In our recent study on biology , we described a species of Sperchios that is new to science: Alburnoides Economoui . We also describe the Macedonian-Thessalian species of freshwater spirline as Albernoides thessalicus (Stephanidis 1950), Thessaian spirline. Presumably this includes the Achyos/Vardar fish in Macedonia (so the Thessalian fish is not endemic to Greece). Morphologically, there are only very small differences and a lot of "overlapping of characters" (different shapes and forms of organs show variability). Spearlin Spearsius has a small, almost full keel, a slight kyphosis at the back of the head and many other subtle features - all of which require expert measurements to identify the species. Identification marks are clearly visible in adults but not in young fish.
Finally, our paper shows that more work is needed to finalize Greek fish names (the Epirus/Albanian spiral cases remain). We also show for the first time that the candidate species of Albernoides bipuntatus (European Spirulina) in the Danube does not occur in Greece.
Why did we call him A. Economui ?
We thought of different names. For example, in 480 BC. Leonidas, the famous Spartan who fought the Persians at the Sperius River. But soon Alcibiades N. Alcibiades n. One of the most important works that he and Roberta Barbieri (and others) did was the inventory of all water bodies in the Peloponnese and western Greece ( Economo et al. 1999). This is a wonderful unpublished report that provides fascinating information about the natural course of epidemics in Greece. Alex worked hard in the late 1990s (along with another intrepid researcher, Dr. Charalambous Dulas) on biodiversity conservation in the Spurious Basin. They made Sperchios famous for their rare fish, with a special focus on Greek pike (they actually made the first transfer to save a group of sprats, and it was a success). Alkis's research method is thorough, sustained and thorough investigation. During his marine career (in the late 1970s) he became interested in biosecurity; His work, especially in freshwater, has helped many of us in Greece focus on the importance of continuing our work. For me, Alkis played an important role in the implementation of the Water Framework Directive (WFD) for Greece, especially the scientific aspects of the 'terms of reference' (Economou 2003) which were mentioned in one of his speeches. For the past 15 years, Greece has led the research and development of important fish technologies on World Food Day (e.g. Economou et al., 2016). This includes at least 7 attempts to create a bioscoring index and a recently successful model-based index (Tachos et al. 2016; Zogaris et al. - forthcoming). Alex is very helpful and has worked with almost all etiologists in Greece, especially those who assessed the conservation status of Greek fishes and published our first river basin species lists (Economo et al., 2007) and detailed fish lists (Barbieri et al.) during the projects. Buy 2015) was the first director of the new Amalgam Institute during the recent crisis in Greece. He is the perfect leader.
