Aim  The Mediterranean region is a species‐rich area with a complex geographical history. Geographical barriers have been removed and restored due to sea level changes and local climatic change. Such barriers have been proposed as a plausible mechanism driving the high levels of speciation and endemism in the Mediterranean basin. This raises the fundamental question: is allopatric isolation the mechanism by which speciation occurs? This study explores the potential driving influence of palaeo… 

Biogeography of cyclamen: an application of phyloclimatic modelling

The biogeography of Cyclamen is investigated and the impact of palaeogeography and palaeoclimate change on the distribution of the genus is assessed, using techniques of phyloclimatic modelling and phylogenetic character optimisation to investigate the heritability of climatic preference.

Historical Isolation versus Recent Long-Distance Connections between Europe and Africa in Bifid Toadflaxes (Linaria sect. Versicolores)

Four events of post-Messinian colonization following long-distance dispersal from northern Africa to the Iberian Peninsula, Sicily and Greece are strongly inferred, providing new evidence for the biogeographic complexity of the Mediterranean region.

Insights into Neogene Mediterranean biogeography based on phylogenetic relationships of mountain and lowland lineages of Narcissus (Amaryllidaceae)

The phylogenetic relationships of daffodils (Narcissus), focusing on the lowland subgenus Hermione and the mountain section Apodanthi, are reconstructed and the microevolutionary differentiation of the wide‐ranging Narcissus tazetta group across the Mediterranean is examined.

Tracing the temporal and spatial origins of island endemics in the Mediterranean region: a case study from the citrus family (Ruta L., Rutaceae).

The analyses showed that Ruta invaded the region from the north well before the onset of the Mediterranean climate and diversified in situ as the climate became Mediterranean, and stressed the importance of temporary land connections and colonization opportunity in the biotic assembly of continental fragment and oceanic islands, respectively.

The historical biogeography of Scabiosa (Dipsacaceae): implications for Old World plant disjunctions

Members of Scabiosa appear to have capitalized on adaptations to montane and/or dry conditions in order to colonize similar habitats in different biogeographical regions.

Spatio‐temporal dynamism of hotspots enhances plant diversity

Dating molecular phylogenies indicate that much of the speciation in hotspots did not occur during the Pleistocene but instead occurred during the Tertiary, and a role for vicariance in the generation of diversity is emphasized.

The building of a biodiversity hotspot across a land-bridge in the Mediterranean

The significant turnover between landmasses suggests a common scenario of allopatric speciation that could have been facilitated by the intermittent joining of the two continents in this western Mediterranean biodiversity hotspot.

Dispersal vs. vicariance in the Mediterranean: historical biogeography of the Palearctic Pachydeminae (Coleoptera, Scarabaeoidea)

Although the basal diversification of Pachydeminae around the Mediterranean appears to be related to vicariance events linked to the geological formation of the Mediterranean Basin, dispersal has also played a very important role.

A phyloclimatic study of Cyclamen

Reconstruction of ancestral niches can provide testable hypothesis about the historical development of lineages and demonstrates that major lineages could survive climate change even if many species are lost.

Vicariance patterns in the Mediterranean Sea: east–west cleavage and low dispersal in the endemic seagrass Posidonia oceanica

This work investigated the biogeography and dispersal of P. oceanica at various spatial scales in order to assess the influence of different evolutionary factors shaping the distribution of genetic diversity in this species.

Ecological differentiation of Mediterranean endemic plants

This study illustrates how differentiation in geographically peripheral and ecologically marginal populations may contribute to the diversification of endemic species whose contemporary distributions are disjunct from con-generic species.

Dispersal-Vicariance Analysis: A New Approach to the Quantification of Historical Biogeography

This work presents a new biogeographic method, dispersal-vicariance analysis, which reconstructs the ancestral distributions in a given phylogeny without any prior assumptions about the form of area relationships, and describes the algorithms that find the optimal reconstruction.

RATES OF MOLECULAR EVOLUTION IN NUCLEAR GENES OF EAST MEDITERRANEAN SCORPIONS

Phylogenetic analysis using maximum likelihood revealed a phylogeny that is congruent with that expected based on biogeographic events and in which divergences at synonymous sites are proportional to the dates that the taxa are believed to have split.

REPLICATE PATTERNS OF SPECIES RICHNESS, HISTORICAL BIOGEOGRAPHY, AND PHYLOGENY IN HOLARCTIC TREEFROGS

The phylogenetic relationships among 58 hylid taxa are reconstructed using data from two mitochondrial genes (12S, ND1) and two nuclear genes (POMC, c-myc), and the replicate pattern in Holarctic hylids seems to reflect specialized tolerance for temperate climate regimes or possibly the effects of competition.

Phyloclimatic modeling: combining phylogenetics and bioclimatic modeling.

This is the first study to attempt bioclimatic projections on evolutionary time scales and demonstrates that Phyloclimatics modeling could be repeated for other plant groups and is fundamental to the understanding of evolutionary responses to climate change.

Phylogeny and quaternary history of the European montane/alpine endemic Soldanella (Primulaceae) based on ITS and AFLP variation.

Estimates of divergence times suggest a late Quaternary origin of the genus Soldanella, and it is hypothesized that the latter differentiated in allopatric regions of expansion during glacials, while the former experienced secondary contact at lower elevations in more southern refugia.
