“…Purification and visualisation of PCR products were done as described in Rebernig et al (2010). Analysis of electropherograms and scoring of the AFLP fragments were performed as described in Caković et al (2017), with the exception that the minimum intensity used in RawGeno was set to 75 relative (Nei and Li 1979) was constructed and bootstrapped (2000 pseudo-replicates) using TREECON v.1.3b (van de Peer and Wachter 1997). Cerastium subtriflorum and C. sylvaticum formed a monophyletic clade (bootstrap support, BS, 100%) with unresolved relationships to other taxa; therefore, the data set including only these two species was further analysed, i.e.…”

The south-eastern Alps and the southerly adjacent areas are considered an important refugium for plant species during the Pleistocene glaciations; consequently, they harbour many endemic taxa. One of them is Cerastium subtriflorum, which in this area occurs sympatrically with morphologically similar, but more widespread C. sylvaticum. Here, we used amplified fragment length polymorphisms as well as ITS and plastid DNA sequences to explore phylogenetic relationships between the two species as well as their relationships to other Cerastium taxa previously deemed closely related. Our data show that both species are genetically well-differentiated sister taxa, but their relationship to other taxa remains unclear; both species rather form an independent evolutionary lineage within European Cerastium. Cerastium sylvaticum exhibits low genetic differentiation among populations in the investigated area, suggesting a single Pleistocene refugium in that part of Europe. The much more pronounced genetic differentiation within C. subtriflorum is likely a result of multiple Pleistocene refugia or more recent vicariance among the three disjunct partial distribution areas. Phylogenetic sequence data suggest hybridisation between the two taxa, resulting in a discordant phylogenetic position between ITS and plastid trees of one population of C. subtriflorum. Flow cytometric and multivariate morphometric analyses show that C. subtriflorum and C. sylvaticum differ in their genome size as well as in multiple morphological traits. We provide a taxonomic treatment for both species including an identification key and species descriptions.

The Balkan Peninsula is renowned as a refugium of forest species, which were more widespread in the Tertiary. We here investigated three species from one of the largest genera of flowering plants, Euphorbia, which survived the Pleistocene glaciations in the Balkan Peninsula, but responded differently to Holocene warming. Using ITS sequences, multivariate morphometrics and relative genome size (RGS) measurements, we explored relationships among E. amygdaloides, E. heldreichii and E. orjeni, for which different taxonomic treatments have been proposed. The ITS-inferred phylogenies indicate that all three species form independent evolutionary lineages, which have similar RGS, but differ morphologically, and should thus be treated as independent species. The most enigmatic of them, E. orjeni, was found for the first time after 100 years at its type locality in Montenegro, and, based on herbarium revision, was discovered also in the surroundings of Belgrade. Euphorbia heldreichii is more widespread, distributed in the southern Balkan Peninsula, whereas E. amygdaloides occurs in forests throughout Europe, North Africa and Western Asia. Our study emphasises the importance of further botanical exploration of the Balkan Peninsula, a hotspot of European biotic diversity.

“…Albania is located in the western part of the Balkan Peninsula and is one of the most important Mediterranean biodiversity hotspots ( Caković et al 2018 , Szabolcs et al 2017 ), but is still considered to be the last “terra incognita” for European biodiversity. A series of recent studies, which focused on different groups of plants and animals, brings major contributions to the diversity and distribution of a number of organisms from Albania ( Barina et al 2013 , Graf et al 2018 , Kaltsas et al 2008 , Stevanović et al 2007 ).…”

A new species of the TipulasubgenusMediotipula is described from the south-eastern part of Albania, south-eastern Europe. Morphologically, the new species is most similar to T. (M.) stigmatella Schummel, 1833, but differs mainly with respect to males, having a distinctly shaped posterior margin of tergite 9–10, a widened outer gonostylus and a series of details of the inner gonostylus (anterior end of the anterior arm, shape of the posterior arm), as well as having more bulbous and rounded hypogynal valves in the females. Further morphological differences of the male terminalia between allopatric populations of T. (M.) stigmatella in the Carpathians and Balkans, south-eastern Europe, are discussed.
