The Macaronesian laurel forests (MLF) are dominated by trees with a laurophyll habit comparable to evergreen humid which were scattered across Europe and the Mediterranean in Paleogene Neogene. Therefore, MLF traditionally regarded as an old, 'Tertiary relict' vegetation type. Here we address question if key taxa of relictual. We evaluated relict hypothesis consulting fossil data analyses based on molecular phylogenies 18 representative species. For dating used program BEAST, for ancestral...
Ecological and evolutionary studies largely assume that island populations display low levels of neutral genetic variation. However, this notion has only been formally tested in a few cases involving plant taxa, the confounding effect selection on diversity (GD) estimates based putatively markers typically overlooked. Here, we generated nuclear microsatellite plastid DNA sequence data Periploca laevigata, taxon with an island-mainland distribution area, to (i) investigate whether affects GD...
Islands provide unique opportunities to integrated research approaches study evolution and conservation because boundaries are circumscribed, geological ages often precise, many taxa greatly imperilled. We combined morphological hybridization studies with high-throughput genotyping platforms streamline relationships phylogenies in the endangered monophyletic highly diverse lineage of Solanum Canarian archipelago. Inter-taxa hybridizations were performed, expression was assessed a...
Seed dormancy varies within species in response to climate, both the long term (through ecotypes or clines) and short influence of seed maturation environment). Disentangling processes is crucial understand plant adaptation environmental changes. In this study, local patterns were investigated a narrow endemic species, Centaurium somedanum, order determine environment, population genetic composition climate. Laboratory germination experiments performed measure (1) seeds collected from...
Abstract Molecular dating offers a tool for inferring the time of divergence between two lineages. In this study, we discuss how dated molecular reconstructions are informative different, albeit often intermingled, estimates with regard to fundamental process in island biogeography: colonization (TIC). We illustrate stem age provide information on extant lineage and their closest relatives (i.e. onset differentiation). Such estimates, however, typically poor TIC predictors, as they strongly...
Abstract Insular woodiness (IW), referring to the evolutionary transition from herbaceousness toward on islands, has arisen more than 30 times Canary Islands (Atlantic Ocean). One of IW hypotheses suggests that drought been a major driver wood formation, but we do not know in which palaeoclimatic conditions insular woody lineages originated. Therefore, provided an updated review presence Canaries, reviewed palaeoclimate, and estimated timing origin 24 represent large majority species...
Abstract Aim We explore the idea that most pre‐glacial non‐endemic Canarian flora became endemic to archipelago by extinction of its mainland populations during late Pleistocene glaciations, implying extant is mostly post‐glacial: ‘late endemicity increase hypothesis’. Taxon The native archipelago. Methods statistically compare distributions 2087 and plants across islands. also carry out connectivity analyses using their dispersal paths, obtained connecting all islands occurrence for each...

Many plant species combine sexual and clonal reproduction. Clonal propagation has ecological costs mainly related to inbreeding depression pollen discounting; at the same time, able reproduce clonally have evolutionary advantages being persist when conditions are not favorable for The presence of clonality profound consequences on genetic structure populations, especially it represents predominant reproductive strategy in a population. Theoretical studies suggest that high rate should...
We review the conservation status and threats to endemic vascular flora of Cape Verde islands, mostly based on past two decades collecting, literature herbarium specimens. The application IUCN Red List criteria categories using RAMAS software reveals that 78% plants are threatened (29.3% Critically Endangered, 41.3% 7.6% Vulnerable). Most these endemics have a limited geographical range, half them Areas Occupancy Extents Occurrence < 20 200 km2, respectively. Our data show that, over last...
Abstract Aim The loss of dispersal on islands hypothesis ( LDIH ) posits that wind‐dispersed plants should exhibit reduced potential, particularly if island populations are old. In this study, we tested using a detailed phylogeographical framework across different geographical scales. Location Mainland and areas the Atlantic Mediterranean regions, including Macaronesia (Canary Islands Cape Verde) in strait Sicily. Methods Forty‐five Periploca laevigata , shrub, were sampled. Plastid nuclear...
Abstract Plumbaginaceae is characterized by a history of multiple taxonomic rearrangements and lacks broad molecular phylogenetic framework. Limonium the most species‐rich genus family with ca . 600 species cosmopolitan distribution. Its center diversity Mediterranean region, where 70% all are endemic. In this study, we sample 201 covering described infrageneric entities spanning its wide geographic range, along 64 other genera, representing 23 out 29 genera family. Additionally, 20 sister...
Using a series of standardized sampling plots within forest ecosystems in remote oceanic islands, we reveal fundamental differences between the structuring aboveground and belowground arthropod biodiversity that are likely due to large-scale species introductions by humans. Species beetle spider were sampled almost exclusively from single while soil-dwelling Collembola exhibited more than tenfold higher sharing among islands.

Ecological conditions, such as high habitat diversity and the absence of competitors, have been proposed key determinants patterns speciation observed in oceanic island floras. However, relationship between plant traits lineage diversification has received less attention. Here, we review 120 published phylogenetic population genetic studies three well-studied archipelagos (Canary Islands, Galápagos Hawai'i) to investigate potential associations life history characters (growth form fruit...
Archipelagos provide a valuable framework for investigating phenotypic evolution under different levels of geographical isolation. Here, we analysed two co-distributed, widespread plant lineages to examine if incipient island differentiation follows parallel patterns variation in traits related dispersal and colonization. Twenty-one populations anemochorous Canarian endemics, Kleinia neriifolia Periploca laevigata, were sampled represent mainland congeners contrasting exposures across all...
• Premise of the study: Endemic plants on oceanic islands have long served as model systems for studying patterns and processes evolution. However, phylogenetic studies island frequently illustrate a decoupling molecular divergence ecological/morphological diversity, resulting in phylogenies lacking resolution required to interpret evolution context. The current study uses primarily Macaronesian flowering plant genus Tolpis utility multiplexed shotgun genotyping (MSG) resolving relationships...
ABSTRACT Aim Species–area relationships ( SAR s) on oceanic archipelagos are shaped at least as much by speciation immigration–extinction dynamics. We examine three well‐studied Atlantic to quantify the relative contributions of colonization and diversification individual whole‐archipelago floras. Location Three Macaronesian archipelagos: Azores, Madeira Canary Islands. Methods assessed floras all in order compare s numbers endemic species with respect physical characteristics each...
Understanding patterns of community structure and the causes for their variation can be furthered by comparative biogeographic analyses island biotas. We used woody plant data at local scale to investigate variations in species rarity, alpha, beta, gamma diversity within between three islands from oceanic archipelagoes Azores, Canaries Mascarene. standardized protocols sample ten 50 m × forest plots each with contrasting climate regional pools: Terceira (Azores), Tenerife (Canaries), Reunion...
