Premise of the study: Organisms usually show intercorrelations between all or some of their components leading to phenotypic integration, which may have deep consequences on the evolution of phenotypes. One of the main difficulties with phenotypic integration studies is how to correct the integration measures for size. This has been considered a ch...

Full-text available
The amount of evolutionary information in phylogeographic studies is usually limited due to the low divergence between closely related organisms. Consequently, obtaining the maximum evolutionary information contained in sequence alignments would be of great importance to infer phylogeographic relationships.SIDIER is a software package that allows i...

We have developed and optimized microsatellite loci from a genomic library of Erysimum mediohispanicum. Microsatellites were also tested for cross-amplification in 31 other Erysimum species. A total of 10 microsatellite loci were successfully amplified. They were polymorphic for 81 E. mediohispanicum individuals from two locations in Sierra Nevada...

Cryptic species are superficially morphologically indistinguishable and therefore erroneously classified under one single name. The identification and delimitation of these species is usually a difficult task. The main aim of this study is to provide an inclusive methodology that combines standard and new tools to allow accurate identification of c...

B chromosomes are dispensable chromosomes found in >2000 eukaryotic species, usually behaving as genomic parasites. Most B chromosomes seem to be made up of the same kind of DNA sequences present in the A chromosomes. This sequence similarity makes it difficult to obtain specific molecular probes that may permit B-presence diagnosis without cytogen...
Presentation
We approach the classification, by numerical methods, of semi-deciduous oak woodlands dominated by species of the Q.faginea and Q. canariensis taxonomic complexes in the West Mediterranean biogeographical Sub-Region. An initial typology is obtained from a subset of relevées by unsupervised classification (ISOPAM) and ordination constrained by both...
Article
The study of diamond frogs (genus Rhombophryne, endemic to Madagascar) has been historically hampered by the paucity of available specimens, because of their low detectability in the field. Over the last 10 years, 13 new taxa have been described, and 20 named species are currently recognized. Nevertheless, undescribed diversity within the genus is...
Article
Grapevine (Vitis vinifera L.) diversity richness results from a complex domestication history over multiple historical periods. Here, we used whole-genome resequencing to elucidate different aspects of its recent evolutionary history. Our results support a model in which a central domestication event in grapevine was followed by postdomestication h...
Article
Full-text available
Hybrid zones have the potential to shed light on evolutionary processes driving adaptation and speciation. Secondary contact hybrid zones are particularly powerful natural systems for studying the interaction between divergent genomes to understand the mode and rate at which reproductive isolation accumulates during speciation. We have studied a to...

Plant mating systems may reflect an adaptation to a habitat type, with self-pollination being potentially common in unstable and disturbed conditions. We investigated the reproductive ecology of an Alpine, narrow-range toadflax, Linaria tonzigii Lona (Plantaginaceae), occurring in steep and dynamic mountain screes. We explored self-compatibility an...
Preprint
Grapevine ( Vitis vinifera L.) is one of the most significant crops in the world. Today’s richness in grapevine diversity results from a complex domestication history over multiple historical periods. Here, we employed whole genome resequencing to elucidate different aspects of the recent evolutionary history of this crop. Our results support a mod...
Article
Full-text available
Migration is a process with important implications for the genetic structure of populations. However, there is an aspect of migration seldom investigated in plants: migration between temporally isolated groups of individuals within the same geographic population. The genetic implications of temporal migration can be particularly relevant for semelp...
Article
Full-text available
Polyploidization has played an important role in plant diversification, and variation in ploidy level may be found not only between species of the same genus, but also within a single species. Although establishing the adaptive significance of polyploidy to explain the geographic distribution of cytotypes is challenging, the occurrence of different...

Radioactivity released from disasters like Chernobyl and Fukushima is a global hazard and a threat to exposed biota. To minimize the deleterious effects of stressors organisms adopt various strategies. Plants, for example, may delay germination or stay dormant during stressful periods. However, an intense stress may halt germination or heavily affe...
Article
The isolation by distance model (IBD) predicts that genetic differentiation among populations increases with geographic distance. Yet, empirical studies show that a variety of ecological, topographic, and historical factors may override the effect of geographic distance on genetic variation. This may particularly apply to species with narrow but hi...
Data
Median-joining network of the DQA haplotypes of the European rabbits used in this study. Each circle corresponds to an assigned haplotype (H1-H28; see Fig. 1): in yellow are the haplotypes found in domestic breeds, in black the wild French, in blue the wild Spanish and in red the wild Portuguese rabbits populations. The inferred missing intermediat...

The nomenclature Orcu DQA*01 = Allele A, Orcu DQA*05 = Allele B/E, Orcu DQA*10 = Alle...

The European rabbit (Oryctolagus cuniculus) natural populations within the species native region, the Iberian Peninsula, are considered a reservoir of genetic diversity. Indeed, the Iberia was a Pleistocene refuge to the species and currently two subspecies are found in the peninsula (Oryctolagus cuniculus cuniculus and Oryctolagus cuniculus algiru...

The Baetic mountains, located in the southern Iberian Peninsula, is a major hotspot of biodiversity in the Mediterranean Basin, constituting one of the most important glacial refugia for vascular plants in Europe. Despite their relatively limited extension, the Baetic Mountains contain almost 50% of the total endemic Erysimum species in the Iberian...
Article
Individual variation in the magnitude of inbreeding depression (ID) in plants and its association with phenotypic traits may have important consequences for mating system evolution. This association has been investigated only scarcely, and always considering traits functionally related to autogamy. Here, we explore the association between individua...
Article
It is widely assumed that floral diversification occurs by adaptive shifts between pollination niches. In contrast to specialized flowers, identifying pollination niches of generalist flowers is a challenge. Consequently, how generalist pollination niches evolve is largely unknown.We apply tools from network theory and comparative methods to invest...

Background and AimsHow generalist plants diverge in response to pollinator selection without becoming specialized is still unknown. This study explores this question, focusing on the evolution of the pollination system in the pollination generalist Erysimum mediohispanicum (Brassicaceae).Methods Pollinator assemblages were surveyed from 2001 to 201...
Article
1. Pollen limitation may be a consequence of changes in pollinator abundance, diversity and identity. However, no empirical evidence exists concerning the consequences that the spatial variation in pollinator fauna has on pollen limitation intensity and plant reproduction. In this study, we test the effect that changes in flower-visitor abundance,...
