“…These processes are further enhanced by the lack of gene flow between populations (Segarra‐Moragues et al ., ) and, in some cases, vegetative reproduction (Amat et al ., ). Spatially separate populations display limited evidence for genetic divergence either because they function as a single metapopulation (Blanco‐Pastor et al ., ), or because their separation was relatively recent (Szövényi et al ., ), or because there has been recent admixture. The recent separation and/or the maintenance of gene flow between populations (Casazza et al ., ) may counteract incipient differentiation processes, thereby avoiding bottlenecks, genetic drift and loss of genetic diversity. A dramatic reduction in genetic diversity due to extinctions and bottlenecks (del Hoyo et al ., ; Šajna et al ., ), including founder effects as a result of recent colonization (López‐Pujol et al ., ), leads to a strong loss of genetic diversity and no clear genetic structure can be inferred.…”

Aim The evolutionary history of narrow endemic species has received little attention compared with that of more widely distributed species. Small effective population sizes and long-term isolation of many narrow endemic species make research on their genetic make-up important for their future conservation. In this study we investigated the genetic variation and historical distribution of an isolated plant, the monospecific genus Pseudomisopates, as an example of the phylogeographical history of narrow endemics.Location Central Range, Iberian Peninsula, Mediterranean Europe.Methods We used amplified fragment length polymorphisms (AFLPs), nuclear and plastid DNA sequences and species distribution modelling. Sequence data were analysed using statistical parsimony, molecular dating, and a coalescent-based Bayesian model of isolation with migration. Genetic diversity and differentiation analyses based on AFLP data were performed. We compared the detection of clones using AFLPs with the results of a previous study that used simple sequence repeats (SSRs).Results AFLP analysis revealed that SSRs underestimate clone number. The coalescent-based Bayesian model of isolation with migration suggested a late Pleistocene divergence between the populations of Pseudomisopates on two mountain massifs (Gredos and La Serrota), despite the presence of a large area suitable for population admixture. Moderate to high levels of genetic diversity and high effective population sizes were inferred.Main conclusions Our results imply that the levels of genetic diversity within narrow endemic species from Mediterranean mountains could primarily be driven by extrinsic historical factors, rather than by intrinsic species-specific factors depending on their own biological characteristics. Narrow endemics are widely believed to harbour low genetic diversity because of small effective population sizes. However, this study and others on narrow endemic angiosperms demonstrate that narrow endemism does not necessarily result in low genetic diversity.

“…The entire distribution area is included in the Natura 2000 network as a Site of Community Interest (ČUŠIN 2004). Molecular analyses showed that H. pastinacifolia is a Pleistocene survivor in situ and has widened its distribution little since the end of glaciation (ŠAJNA et al 2012). However, the species is not a habitat specialist and can be found growing in various habitats such as stony grasslands, rock crevices and screes.…”

“…Later research concerning H. pastinacifolia was mainly focused on syntaxonomy (MARTINČIČ 1958, MARTINČIČ 1961, POLDINI 1978, KALIGARIČ 1997, KALIGARIČ and POLDINI 1997, DAKSKOBLER 1998, DAKSKOBLER 2006. Recently, research into the species' ecology was undertaken (ŠAJNA et al 2009, ŠAJNA et al 2011, ŠAJNA et al 2012, as well as population genetics and phylogeny (ŠAJNA et al 2012). SUŠNIK (1964) did not perform anatomical studies on H. pastinacifolia, and accordingly we have endeavoured to complete the anatomical investigation with the use of contemporary techniques.…”

-We studied the anatomy of a rare narrow endemic species belonging to the Slovenian fl ora -Hladnikia pastinacifolia Rchb. Hladnikia is a monotypic genus with distinct taxonomic position within the Apiaceae family. The anatomical characteristics revealed by light and fl uorescence microscopy provided new insights regarding the pollen, leaf and root characteristics of H. pastinacifolia, improving the understanding of its biology and ecology. Pollination, drought tolerance, life cycle and unattractiveness to herbivores explain the species' persistence in time. Autofl uorescence localized bioactive substances within secretory ducts and oil ducts.

“…Hence, the reason for its limited range, restricted to an area of 6-7 km 2 , remains a puzzling question. Another stenoendemic, Hladnikia pastinacifolia (Apiaceae), a monotypic species with even narrower distribution area, restricted to a few localities of the Trnovski gozd plateau in north-western Dinaric Alps (MAYER 1960,^U[IN 2004, colonizes an even broader range of habitats -stony grasslands, rock crevices and screes ([AJNA et al 2012), reflecting an ability to adapt to a variety of both abiotic and biotic factors. Nevertheless, H. pastinacifolia, like Campanula tommasiniana, remains confined to an extremely narrow distribution area, despite the many available habitats in the vicinity, also without any reasonable explanation.…”

-Campanula tommasiniana is a typical chasmophyte occupying calcareous rock crevices and cracks along a wide range of ecological gradients, demonstrating a high degree of ecological plasticity and stress tolerance with regards to abiotic factors. Generally, three ecologically and floristically distinct groups of stands were recognized and typified according to a sigmatistic approach: (a) Seslerio juncifoliae-Campanuletum tommasinianae ass. nov., with stands occupying higher elevated sites fully exposed to sun and strong winds; (b) Seslerio autumnalis-Campanuletum tommasinianae ass. nov., representing stands predominantly developed within thermophytic beech stands, semi-to fully--shaded by the tree canopy; (c) Cystopteri fragilis-Campanuletum tommasinianae, sciophytic, stands adapted to moisture and cold with high frequency and coverage of bryophytes. Results of DCA analyses using a unimodal model suggest that Campanula tommasiniana is primarily a plant of open and exposed sites of higher elevation despite being most frequently found in rock crevices within thermophytic and altimontane beech forests.
