Introduction
My research interests are focused on evolutionary patterns and processes of vascular plants, both at the macro- and micro-evolutionary levels. I apply phylogenetic and phylogeographic methods, as well as evo-devo approaches and species distribution modelling. My specific research topics include: flower evolution and its relationship with insect pollinators; speciation and colonization in the Mediterranean and Macaronesian regions; and the effect of Quaternary climatic cycles on biodiversity.

Article
Traditional classification of speciation modes has focused on physical barriers to gene flow. Allopatric speciation with complete reproductive isolation is viewed as the most common mechanism of speciation. Parapatry and sympatry, by contrast, entail speciation in the face of ongoing gene flow, making them more difficult to detect. The genus Iberod...

Colonization is a central topic in ecology and one of the cornerstones of island biogeography. Although the evolutionary history of island species is widely studied, the quantification of colonization is particularly challenging because the same area may be colonized multiple times by the same species, whereas initially successful colonization even...

Oceanic archipelagos comprise multiple disparate environments over small geographic areas and are isolated from other biotas. These conditions have led to some of the most spectacular adaptive radiations, which have been key to our understanding of evolution, and offer a unique chance to characterise the genomic basis underlying rapid and pronounce...

Euphorbia canariensis is one of the most iconic species of the Canarian flora. It is one of the two cactus-like species of Euphorbia in the Canary Islands, but while the other species (E. handiensis) only occurs in the Jandía peninsula (south of Fuerteventura), E. canariensis is widely distributed in the archipelago. Although both species belong to...

Researchers in phylogenetic systematics typically choose a few individual representatives of every species for sequencing based on convenience (neighboring populations, herbarium specimens, samples provided by experts, garden plants). However, few studies are based on original material, type material or topotypic material (living specimens from the...
Article
Sedges (Cyperaceae) are commonly pollinated by wind, but some transitions from wind to insect pollination have been reported in tropical sedges. Despite being a temperate sedge, the pollination strategy of Rhynchospora alba may partly depend on insects, as suggested by its white-colored inflorescences. Here we quantify the contribution of insects t...
Article
The high diversification rates of plant lineages in the Mediterranean Basin hotspot have been linked to a complex interaction of climatic stressors, geographic isolation and soil type, but the question remains as to which of these factors has been the most significant environmental driver of recent speciation. Here, we draw on distributional data f...

Peripheral populations (i.e., those occurring on the edge of a species’ distribution range) can have different origins and genetic characteristics, and they may be critical for conservation of genetic diversity. We investigated European peripheral populations of Scrophularia arguta, a widespread, annual plant distributed from Arabia to Northwest Af...
Article
Drosophyllaceae is the only plant family endemic to the Mediterranean Floristic Region. It includes a single species, the carnivorous Drosophyllum lusitanicum, which is hypothesised to be a relict plant. Our aim here is to reconstruct the evolutionary history of Drosophyllum to evaluate whether the African-European disjunction across the Strait of...
Article
Poor morphological and molecular differentiation in recently diversified lineages is a widespread phenomenon in plants. Phylogenetic relationships within such species complexes are often difficult to resolve because of the low variability in traditional molecular loci. Furthermore, biological phenomena responsible for topological incongruence such...
Article
Geography and climate have been the main drivers of evolution in recent geological epochs. While new lineages of species have been formed in the last millions of years (speciation) and others have vanished as a result of historical climate changes (extinction), some ancient lineages appear to have persisted to the present day without net diversific...
Article
Accurate inference in phylogeography requires appropriate sampling strategies. Complex questions demand a large sample size at both the population and genetic levels to obtain precise reconstructions. This is the case of the phylogeographic history of Cistus monspeliensis, a plant that displays low plastid (cpDNA) diversity in the Mediterranean Bas...

- Traditional classification of speciation modes has focused on physical barriers to gene flow. While allopatry has been viewed as the most common mechanism of speciation, parapatry and sympatry, both entail speciation in the face of ongoing gene flow and thus both are far more difficult to detect and demonstrate. Iberodes (Boraginaceae, NW Europe)...

Floral nectar spurs are considered a key innovation promoting diversification in angiosperms. Spurs are tubular outgrowths of floral organs containing a nectar reward for pollinators. It is hypothesized that they mediate reproductive isolation by promoting pollinator specialization. Here we apply a multidisciplinary (phylogenetics, pollination ecol...
Article
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 vari...

Chromosome evolution has been demonstrated to have profound effects on diversification rates and speciation in angiosperms. While polyploidy has predated some major radiations in plants, it has also been related to decreased diversification rates. There has been comparatively little attention to the evolutionary role of gains and losses of single c...
