“…The marbled pattern colouration seems not to be correlated with haplotypes of S. marmoratus . The sister species representative of the ‘marble trout lineage’ in Croatia and Montenegro is Salmo dentex (Snoj et al, ; Pustovrh et al, ). The partial marble pigmentation observed in Croatia and Montenegro is possibly the result of convergence, as happened in several populations of Salmo trutta from Norway with typical marble pigmentations (Delling, ).…”

Summary An updated, corrected checklist of both native and established alien freshwater fish species in Italy is given based on molecular, morphological and biogeographical data. Some 12 native species, reported as conspecific with transalpine species in official Italian ichthylogical literature, are in fact endemics. Previous taxonomic confusion has resulted in the introduction of several alien species, either with official stockings or mixed in as impurities. Rehabilitated species include the cyprinids Scardinius hesperidicus, Scardinius scardafa and Telestes savigny from northern Italy, as well as Squalius ruffoi and the Telestes comes from southern Italy. Squalius albus is a junior synonym of S. squalus. The endemic gudgeon, previously assigned to the genus Romanogobio, is returned to the genus Gobio (G. benacensis). Phoxinus lumaireul is a junior synonym of P. phoxinus. Among the Salmonidae, Salmo cenerinus is a junior synonym of S. marmoratus, while Salmo farioides represents the trout species of the Adriatic lineage for which a neotype is designated. Thymallus aeliani represents the endemic lineage of grayling of the Adriatic populations. The esocid Esox cisalpinus is an endemic pike species and Esox flaviae is a junior synonym; the extensive exportation as well as the presence of this species throughout Europe is possibly due to humans. Among sculpins, Cottus scaturigo and C. ferrugineus are junior synonyms of C. gobio. The International Union for Conservation of Nature (IUCN) categories for native species of Italy are updated. At present, 52 native freshwater fish species are listed: 2 are extinct (Acipenser sturio and Huso huso), 12 are critically endangered, 7 endangered, 10 vulnerable, 3 near‐threatened, 15 low concern and 3 data‐deficient; 35 species are the result of human transfers. Among the 51 introduced species, 6 are recently established (Leuciscus leuciscus, Oreochromis niloticus, Poecilia reticulata, Xiphophorus helleri, Amatitlania nigrofasciatus, Hemichromis sp.), 37 are already established, 5 are probably established and 3 are non‐established Chinese carp, maintained in the wild by intensive stockings. The family most involved is the Cyprinidae, with 22 alien and 20 native species.

“…: Previšić et al , 2009; aquatic leaf beetle Macroplea mutica : Mende et al , 2010) and terrestrial animals (brown bear Ursus arctos : Taberlet & Bouvet, 1994) have reported heterogeneous population structure within the Adriatic basin, and confirmed the arrangement of populations into distinct Balkan clades. Specifically, both Snoj et al (2010) and Pustovrh et al (2011) have also demonstrated the distinction between various trout populations [ S. trutta , Salmo dentex (Heckel 1851) and Salmo marmoratus Cuvier 1829] of River Neretva from those draining into Lake Skadar, which is especially noteworthy given the small geographic scale ( c . 150 km).…”

Phylogeography of isolated freshwater three‐spined sticklebackGasterosteus aculeatuspopulations in the Adriatic Sea basin

Analyses of mitochondrial (mt) DNA and microsatellite variation were carried out to examine the relationships between 10 freshwater populations of three-spined sticklebacks Gasterosteus aculeatus along the eastern coast of the Adriatic Sea. Partial sequences of the mtDNA control region and cytochrome b gene, in addition to 15 microsatellite loci, were used to analyse populations from four isolated river catchments. Results uncovered an Adriatic lineage that was clearly divergent from the European lineage, and confirmed that the most divergent and ancient populations are located within the Adriatic lineage as compared with other European populations. Two northern Adriatic populations formed independent clades within the European mitochondrial lineage, suggesting different colonization histories of the different Adriatic populations. Nuclear marker analyses also indicated deep divergence between Adriatic and European populations, albeit with some discordance between the mtDNA phylogeny of the northern Adriatic populations, further highlighting the strong differentiation among the Adriatic populations. The southern populations within the Adriatic lineage were further organized into distinct clades corresponding to respective river catchments and sub-clades corresponding to river tributaries, reflecting a high degree of population structuring within a small geographic region, concurrent with suggestions of existence of several microrefugia within the Balkan Peninsula. The highly divergent clades and haplotypes unique to the southern Adriatic populations further suggest, in accordance with an earlier, more limited survey, that southern Adriatic populations represent an important reservoir for ancient genetic diversity of G. aculeatus.

“…Such taxonomic changes have recently been shown for several fishes in the Aoos basin; for example, Markova et al (2010) insist that the Aoos is in fact inhabited by Barbus prespensis which also means that B. rebeli should be excluded from the Greek freshwater fish list, since this taxon is now considered endemic to a few river drainages in central western Albania. Furthermore, in the previous Greek checklists, S. dentex is noted as possibly inhabiting the Aoos (Kotellat & Freyhof, 2007;Economou et al 2007), yet this fish has been shown not to be a valid species (Snoj et al, 2010). Other serious taxonomic issues include the tiny sand gobies of Western Greece.…”

Recent contributions to the distribution of the freshwater ichthyofauna in Greece

et al. 2012

In this paper we supplement Greece's recent annotated inventory of freshwater fishes per hydrographic basin with recent distributional data and taxa alteration information, based on field sampling and a literature review up to September 2011. We report on newly documented distributional records of 31 fish species plus one unidentified taxon, within 35 hydrographic river basin units in Greece. These new records include 14 native fish species, seven alien and 12 translocated. Translocated taxa are distinguished from aliens, in order to report species non-indigenous to a basin but native within the same ecoregion. Twelve hydrographic basin units are newly added to the roster of ichthyologically explored river basins following a previous basin-scale inventory method (the total is now 117). This review increases the number of Greece's freshwater fish taxa to 167, since four new species are added to the list (Carassius langsdorfii, Neogobius fluviatilis, Telestes alfiensis, Millerigobius macrocephalus) and two are deleted (Salmo dentex, Barbus rebeli) due to taxonomic changes. Taxonomic changes will probably continue to alter the national list since phylogenetic research is ongoing on several taxa in many parts of the country.
