“…This assertion is based on fossil and palaeoclimatic evidence plus the current distribution of these species and their intolerance to low winter temperatures or the typical dry season of the Mediterranean region (van der Hammen et al. , 1971; Jermy, 1984; Costa Tenorio et al. , 1997; Barrón & Peyrot, 2006; Pulido et al.…”

“…The existence of refugia is thought to be crucial in explaining the presence of Tertiary relict species in Europe's southern peninsulas. This assertion is based on fossil and palaeoclimatic evidence plus the current distribution of these species and their intolerance to low winter temperatures or the typical dry season of the Mediterranean region (van der Hammen et al, 1971;Jermy, 1984;Costa Tenorio et al, 1997;Barró n & Peyrot, 2006;Pulido et al, 2008). However, such evidence does not unequivocally indicate that their current rarity and fragmented distribution are directly driven by the scarcity and scattered distribution of suitable refugia.…”

“…Historical climatic factors and the existence of enclaves that have served as refugia are basic to any understanding of the persistence of subtropical and warm‐temperate species in western Europe (Jermy, 1984; Costa Tenorio et al. , 1997; Svenning & Skov, 2007).…”

Aim To assess the importance of climate and human pressure as factors limiting the past, present and future distribution of Prunus lusitanica L. (the Portuguese laurel), a relict of Europe’s ancient subtropical laurel‐forest flora. Location The Iberian Peninsula. Methods A census was taken of the current populations of P. lusitanica in the Iberian Peninsula and the threats they face. The potential distribution of the species was modelled under current climatic conditions and under simulations of the climate for the Last Glacial Maximum (LGM), the mid‐Holocene and the year 2080. Results The present total population of 31,000 individuals is largely distributed as small, fragmented subpopulations, often threatened by agriculture or forestry. The species’ current range is much smaller than its potentially suitable range. During the LGM, P. lusitanica would have been constrained to a limited number of sites along the Atlantic coast. In the mid‐Holocene, its potential range was much wider than during the LGM and similar to that of the present day. Under the 2080 climate scenario its potential range is reduced by almost 40% compared to that of the present. This reduction includes the loss of territories currently home to three‐quarters of its Iberian population. Main conclusions Drastic climatic changes and the existence of refugia are usually invoked to explain the rarity and fragmented distribution – yet persistence – of a subtropical flora in southern Europe. The availability of climatically suitable habitats is, however, not necessarily the main factor limiting its distribution. Human impact would appear to have been – and continues to be – of fundamental importance in the current population sizes and potential range of P. lusitanica in the Iberian Peninsula.

“…These numbers reflect that most of the diversity of European Dryopteris is in the southern, Mediterranean region, and the number of species diminishes gradually from south to north. In-depth historical biogeographic studies of the entire European Dryopteris flora have not yet been undertaken, but Jermy (1984) postulated that of 16 species in the Mediterranean area, 12 evolved in Southern Europe or spread from West-Central Asia or Macaronesia. Kalliola (1937) concluded that D. fragrans had a much larger distribution in Kola and Finnish Lapland during the early postglacial period, when the climate was more continental than at present.…”

What We Do (and Don't) Know About Ferns: <I>Dryopteris</I> (Dryopteridaceae) as a Case Study

Abstract-Ferns are the second largest group of vascular land plants after the angiosperms, but remain chronically underrepresented in studies of plant phylogeny, biogeography, physiology, and genomics. The genus Dryopteris, the woodferns, is a large group with a worldwide distribution, and recent research has made it one of the better understood fern genera and a potential model for understanding many aspects of fern biology and evolution. Here we review historical and current understanding of the genus, and outline promising avenues of future research in ferns for which Dryopteris is an ideal study system, particularly for research on polyploid complexes, biogeographic distributions, and physiological ecology.
