“…The majority of these taxa occur either in coastal or lowland areas, where land-use change due to human activities has been intensifying during the past two decades ( (accessed on 3 September 2020)); [ 85 , 86 ]) leading to habitat loss and degradation, two major factors related to increased extinction rates [ 7 , 12 , 22 ], especially in the Mediterranean [ 85 ]. Currently, only one taxon ( Isoetes heldreichii ) is presumably extinct in Greece [ 87 ], while other taxa that were considered extinct, were recently rediscovered (e.g., [ 88 , 89 ]). The recorded extinction rate in Greece is thus lower than Italy [ 79 ], Spain [ 90 ], other areas with Mediterranean-type climate (e.g., [ 91 ]) or global estimates [ 7 , 9 , 22 ], and cannot be attributed to lower collection effort, since Greece has been extensively botanized during the past two centuries [ 92 ], with collection intensity intensifying the past decades, which resulted in the rediscovery of many presumably extinct taxa [ 92 ].…”

Human-induced biodiversity decline has been on the rise for the past 250 years, due to various causes. What is equally troubling, is that we are unaware which plants are threatened and where they occur. Thus, we are far from reaching Aichi Biodiversity Target 2, i.e., assessing the extinction risk of most species. To that end, based on an extensive occurrence dataset, we performed an extinction risk assessment according to the IUCN Criteria A and B for all the endemic plant taxa occurring in Greece, one of the most biodiverse countries in Europe, in a phylogenetically-informed framework and identified the areas needing conservation prioritization. Several of the Greek endemics are threatened with extinction and fourteen endemics need to be prioritized, as they are evolutionary distinct and globally endangered. Mt. Gramos is identified as the most important conservation hotspot in Greece. However, a significant portion of the identified conservation hotspots is not included in any designated Greek protected area, meaning that the Greek protected areas network might need to be at least partially redesigned. In the Anthropocene era, where climate and land-use change are projected to alter biodiversity patterns and may force many species to extinction, our assessment provides the baseline for future conservation research, ecosystem services maintenance, and might prove crucial for the timely, systematic and effective aversion of plant extinctions in Greece.

“…The apparent consensus as to the geranialean affiliations of this genus was questioned by Bortenschlager (1 967) who, based on studies of pollen morphology, suggested that Bierberstekzu should be recognized as a family near the Potentillae in Rosaceae. In addition to this, the presence of anacampylotropous ovules (Kamelina & Konnova, 1990), the lack of a persistent elongated central column in the ovary, a reduced tegmic seed coat (Boesewinkel, 1997), leaf morphology (Tutel, 1982), flavonoid patterns (Bate-Smith, 1973) and a basic chromosome number of x = 5 (Aryavand, 1975, Constantinidis, 1996 distinguishes Bzebersteiniu from all geranialean taxa.…”

Phylogenetic analysis of rbcL and atpB gene sequences from Biebersteinia Stephan (represented by B. orphanidis Boiss.) and from selected taxa of the rosids I and II clades does not support traditional grouping of this genus in Geraniaceae s. s. nor in Geraniales, but indicates strong support for a position nested within Sapindales (as recently delimitated). The rbcL and atpB phylogenies obtained were congruent but differently resolved and do not link Biebersteinia to any other clade within Sapindales. Biebersteinia is on a long branch on its own which, given the particular combination of apomorphic morphological characters, justifies familial status.

“…Due to the special climatical conditions of the dolines and sinkholes, they often serve as habitats of rare and valuable species (Budai 1913;Yannitsaros et al 1996;Tan et al 1997;Vojtkó 1997;Varga et al 2000;Bátori et al 2006;Virók & Farkas 2008), among which we can also find endemisms (Egli et al 1990;Egli 1991;Brullo & Giusso del Galdo 2001;Søndergaard & Egli 2006). In the case of climate changes, the dolines and sinkholes may serve as shelters and their vegetation is often more ancient than the neighbouring vegetation (Jakucs 1952).…”

This paper deals with the forest vegetation of the lower part of the dolines in Mecsek Mts. (South Hungary). In order to characterize this vegetation type, samples were compared to the 6 plant communities occurring in the neighbourhood of the dolines. Considering the vegetation texture and species composition, the vegetation of the dolines resembles mainly the extrazonal beechwoods (Helleboro odori-fagetum) and local ravine forests (Scutellario altissimae-Aceretum) that preserve several mountain, subatlantic relict species in this area. Our study revealed that the plant communities characteristic of the karst surface of Western Mecsek are arranged along a moisture and nutrient gradient. In this system, the habitat conditions of the dolines are similar to those of the beech forests and the local ravine forests, fresh and relatively rich in nutrients. In the karst, dominated by oak-hornbeam and beech forests, effects of the thermal inversion are the most spectacular where beech forests follow turkey oak-sessile oak forests and oak-hornbeam forests on the lower part of the doline slopes. The described vegetation type of these depressions is developed by edafic factors; its identification as a separate association is not supported by the analyses.
