European Spirlins: More species needed!

The only nameless "Spercheios Sperlin" in the Spercheios river (we will name it soon). This individual was captured near Lamia in the spring (note the "beak" mark on the upper body...maybe the drought?).

Athens, June 30, 2017

I am not for segregation, in the name of conservation. Splitting occurs when a previous species "splits" into others after further study. Based on the phylogenetic species concept (PSC), a species must be shown to be a single evolutionary lineage. PSC considers the species to be the smallest diagnosable population of individuals with both parental and descent, even if the divergence is relatively recent or limited to one or very few morphological or genetic traits. So in this type of concept, there are no more SUBTHEMES. Gone are the days of subspecies... And PSCs dominate zoology (except birds, not yet).

Therefore, chromosomal chemistry is primarily used to study variation, trace isolated populations, and describe distinct and discrete lineages. Molecular work also examines relatedness and presumed closeness of hereditary relationships. It's an interesting world. molecular methods now describe animals and plants; a new microscopic natural history.

In our latest publication, a large group of scientists studied the phylogenetic relationships and classification of Spirulina (also known as Schneiders or Rifeldaces) of the genus Alburnoides. (They look a lot like American Black's river fish).

Molecular analysis identified 17 Eurasian lineages, divided into two main groups: Ponto-Caspian and European . Lineage richness is closely linked to the existence of known glacial refugia and isolated long-term basins . We claim an "underestimation of the specific richness" of the genus Alburnoides. genetic analysis confirms the validity of 11 morphologically recognized species; Additionally, four phylogenetic lineages have been identified that require their description as separate species.

The nominal range of species of A. bipunctatus sensu stricto has been redefined. This means that there will be no more named species in Greece. The Southern Balkans are called the home of Alburnoid speciation. The river systems of Albania and the wider Ponto-Caspian Basin show the complexities between delineating certain species and understanding evolutionary processes; these areas require further study. A. ohridanus shows considerable divergence from the A. prespensis complex (the Aoos River fish is included in the "A. prespensis complex" but has not yet been formally described or named). It has been confirmed that the unnamed species from the Sperkios River is genetically far removed from all others.

Thessaly Sparrow – Related to the Strymonian Sparrow (soon to be validated as Alburnoides thessalicus ). (Photo with my Czech colleagues from the expedition). Note that dead groundfish have more intense pigmentation. (God, forgive me for all the pain I caused the fishes a long time ago, I only felt it for a moment).

Strymon sperlin, now officially Alburnoides stymonicus . (Photo taken in recent years from the Agitis tributary).

The mysterious "Prespa Sperlin Complex" on the still unnamed Aoos River. We recommend calling it Αlburnoides. cf prespensis pending new research. (Photo Aoos 2005 with friend Uwe Düssling).
