“…The last method, when applied to our data set would probably increase the proportion of endemic taxa in sub‐alpine and alpine zones as the total species pool of these belts is considerably lower than that in the montane belt (cf. Aeschimann et al ., ). Unfortunately, there are no available data on detailed altitudinal distribution of all native vascular plants in the Western Carpathians to confirm this assumption.…”

“…() applied a more detailed distribution survey across a finely defined altitudinal gradient, and Aeschimann et al . () expressed endemic richness as a proportion of endemics of total numbers of species for a given belt. The last method, when applied to our data set would probably increase the proportion of endemic taxa in sub‐alpine and alpine zones as the total species pool of these belts is considerably lower than that in the montane belt (cf.…”

“…Highly elevated OGUs thus show greater altitudinal variation suitable for a larger assembly of endemics with different altitudinal preferences than lower elevated OGUs. In the Alps the endemic richness pattern culminates at higher altitudes (Essl et al ., ; Aeschimann, Rasolofo & Theurillat, ); this is not the case for the Western Carpathians. This discrepancy might be due to the different approach applied for the calculation of endemic richness.…”

The Western Carpathians, as part of the Carpathian mountain range, are one of the most important centres of vascular plant endemism in Europe. We analysed the distribution patterns of 85 vascular plant taxa (excluding apomictic groups) that are endemic to this region (Western Carpathian endemics) or to the whole Carpathians (pan‐Carpathian endemics) across 125 operational geographic units (OGUs) delimited in the area, and assessed their niche and altitudinal breadths, habitat preferences, and life‐history traits. Spatial pattern of endemic richness was not random, but was geographically structured with the highest values recorded in the OGUs from the central part of the Western Carpathians. The pan‐Carpathian endemics had, on average, larger distributional ranges in the Western Carpathians than the Western Carpathian endemics and showed slightly different distribution patterns, probably affected by historical migrations from the Eastern and Southern Carpathians. A significantly higher proportion of endemics occurred in open non‐forest habitats (i.e. rocks/screes and grasslands, 74%) than in forests (18%). Almost 64% of endemic taxa occurred on calcareous bedrock, while only 12% and 21% were confined to siliceous or both types of bedrocks, respectively. We found a strong positive correlation between the distribution range of endemic taxa and altitudinal and niche breadths. There were no differences between diploids and polyploids in any of tested traits, niche and altitudinal breadths and range size. The best linear model explained almost 75% of endemic richness patterns, and included maximal altitude and its interactions with the proportion of calcareous areas and total area of OGUs as the best predictors. Our data suggest that both environmental conditions and historical migrations have shaped the current pattern of endemic richness in the Western Carpathians.

“…This pattern has already been demonstrated by several studies in the Alpine regions (e.g. RÜBEL, 1911;REISIGL & PITSCHMANN, 1958;GRABHERR & al., 1995;THEURILLAT & al., 2003;AESCHIMANN & al. 2011) and less often in Mediterranean regions (POLUNIN, 1980).…”

This article analyzes partial data published in the "Flora Corsica" in order to characterize the Corsican vascular flora. These analyses focus on different aspects of the flora such as species richness, taxonomic distribution, abundance and life-forms at different vegetation belts, habitats and substrates. The results are compared with other geographic regions, particularly from the European Mediterranean and adjacent areas. The decrease of species richness with an increase of altitude as well as the sharp decrease of Fabaceae has been confirmed. Regarding the biological spectrum, the decrease of the therophytes with an increase of altitude is obvious and compensated by the increase of the hemicryptophytes. On Corsica several peculiarities have been highlighted in the different ecological compartments: 1. the littoral and the cryo-oromediterranean belts appear to be very different from the others in many features; 2. the rocky habitats are shown to be especially important for the diversity of families such as Poaceae and Caryophyllaceae; 3. calcareous areas are shown to be extremely important for the alpha diversity as well as for the restricted range taxa. Finally, the specificity of the flora growing on the ultramafic outcrops is confirmed and emphazised.

“…A su vez, América, Oceanía y bastantes archipiélagos comenzaron a recibir también plantas del resto de continentes. Esta realidad fitogeográfica cultural ha dado pie en las últimas décadas a numerosos estudios especiales ecológicos y biogeográficos sobre plantas alóctonas (Lodge, 1993;Rosenzweig, 2001;Sanz et al, 2004;Pauchard y Shea, 2006;Chytrý et al, 2008;Alexander y Edwards, 2010, entre muchísimos otros) e, igualmente, están comenzando a ser discriminadas en las floras y analizados sus espectros (Pyšek et al, 2004;Acedo y Llamas, 2007;Campos y Herrera, 2009;Aeschimann et al, 2011).…”
