Abstract Aim The aims of this study were to assess the distribution putative Mediterranean refugia plants, compare locations and those regional hotspots plant biodiversity, provide a critical analysis refugium paradigm. Furthermore, we consider how biogeographical genetic results can be combined guide global conservation strategies. Location region. Methods We started from detailed scientific literature (1993–2007) in order identify region, based on intra‐specific phylogeographical studies...
Microrefugia, defined as small areas maintaining populations of species outside their range margins during environmental extremes, are increasingly recognized for role in conserving the face climate change. Understanding microclimatic dynamics becomes crucial with global warming leading to severe temperature and precipitation changes. This study investigates phenomenon short-term climatic decoupling within microrefugia its implications plant persistence Mediterranean region southeastern...
In the context of global warming, a clear understanding microrefugia-microsites enabling survival species populations outside their main range limits-is crucial. Several studies have identified forcing factors that are thought to favor existence microrefugia. However, there is lack evidence conclude whether, and what extent, climate encountered within existing microrefugia differs from surrounding climate. To investigate this, we adopt "bottom-up" approach, linking marginal disconnected...
Abstract Aim Phylogeography of fruit trees is challenging due to recurrent exchanges between domesticated and wild populations. Here we tested the eastern refugium hypothesis (ERH) for carob tree, Ceratonia siliqua , which supports its natural domestication origins in Mediterranean a feral origin west. Location basin. Taxon L., Leguminosae . Methods A phylogenetic reconstruction based on two nuclear one plastid sequences was performed estimate divergence time tree sister species, oreothauma...
Background and aims – The thermophilous woodlands of the Mediterranean region constitute reservoirs genetic resources for several fruit trees. Among them, carob tree (Ceratonia siliqua) is a key component traditional agroecosystems but its ecology was never assessed at scale whole distribution area. Fortunately, phytosociological literature shelters invaluable issues in conservation, among them possibility to analyse plant biodiversity regional or continental scale. Here, we present results...
Intense research efforts over the last two decades have renewed our understanding of plant phylogeography and domestication in Mediterranean basin. Here we aim to investigate evolutionary history origin carob tree (Ceratonia siliqua), which has been cultivated for millennia food fodder. We used >1000 microsatellite genotypes delimit seven units (CEUs). investigated genome-wide diversity patterns CEUs with 3557 single nucleotide polymorphisms generated by restriction-site associated DNA...
La place de l’Homme dans l’environnement méditerranéen apparaît plus que jamais comme déterminante, puisque ses impacts et choix gestion déterminent le maintien la forte biodiversité du bassin méditerranéen. Constitué 10 hotspots régionaux une cinquantaine zones refuges, région méditerranéenne est fragilisée par rapidité l’ampleur des changements environnementaux en cours ou prévus à court terme. À échelle fine, hotspot régional Alpes maritimes, représente important centre d’endémisme l’arc...
Abstract The Maritime and Ligurian Alps represent a regional hotspot of plant biodiversity found in the Mediterranean. Historical factors, complex geomorphology habitat diversity may have played key roles to mould biogeographical singularity this area. This study represents first phylogeographic attempt better assess evolutionary history an endemic ( Gentiana ligustica ), which is throughout hotspot, across large altitudinal ecological gradient. Here, we examine how historical topographical...
Hakea sericea Schrad. & J.C.Wendl. (Proteaceae) is a shrub or small tree native to south-eastern Australia. The species has been introduced other countries; it naturalised and become invasive in France, New Zealand, Portugal, South Africa. During the review process of Pest Risk Analysis for European Mediterranean Plant Protection Organization (EPPO) on 2017, actual identity plant causing major negative biodiversity impact Portugal was questioned. Flowering material from additional...
Abstract The island of Corsica is a Mediterranean hotspot plant biodiversity characterized by high rate endemism, but also lack studies combining genetic diversity and conservation. In Corsica, the dioecious Corso‐Sardinian endemic Mercurialis corsica Cosson (Euphorbiaceae) occurs across wide ecological gradient, number populations have decreased considerably over last century. main aim this study was to examine patterns occurring in Corsican M. , depending on their location demographic...

Abstract Acis nicaeensis and A. fabrei are two endemic geophytes from the Maritime Alps Vaucluse (Nesque basin) respectively. The aims of this study to establish distinctive morphological characters between snowflakes, examine chorology demography populations, in addition with evaluation their ecological requirements. Among most discriminating characters, leaf width, stigma—anther separation, number internal tepal veins diameter epigynous disk useful. Thirty—six existing populations have...
