Article
Plant species adapted to coastal systems are suffering severe declines. This is the case of the critically endangered Juniperus navicularis, which colonizes fossil dunes in the southwestern Iberian Peninsula and grows in the understory of pine plantations. This endemic juniper presents low reproduction rates and a decreasing number of populations h...

Calluna vulgaris (Ericaceae) is the most widespread and prevalent woody species of the European dry heathland, from the African side of the Strait of Gibraltar to northern Europe. However, previous biogeographic analyses of this species have ignored the western Mediterranean region, despite its preponderant role as a major glacial refugium for Euro...

The genus Baldellia Parl. (Alismataceae) in the Iberian Peninsula, Balearic Island and MoroccoPalabras clave. Baldellia repens, taxones infraespecíficos, W mediterráneo.Key words. Baldellia repens, infraespecific taxa, W mediterranean.
Article

The South African Cape fynbos heath Erica coccinea subsp. coccinea is polymorphic for post-fire regeneration mode (seeder/resprouter), flower colour (red/yellow), flowering time (summer-autumn/winter-spring), as well as anther size. These polymorphisms tend to occur between, rather than within, populations. Here, we aimed to understand flower colou...
Article
In the western Mediterranean, although considerable attention has focused on the role of the Strait of Gibraltar on diversification of biota, relatively few studies have looked at the biogeographical consequences of the large rivers as barriers to gene flow on North African and southern European taxa. To investigate the importance of river basins i...
Article
Full-text available
Reproductive biology of carnivorous plants has largely been studied on species that rely on insects as pollinators and prey, creating potential conflicts. Autogamous pollination, although present in some carnivorous species, has received less attention. In angiosperms, autogamous self-fertilization is expected to lead to a reduction in flower size,...

In phylogeography, DNA sequence and fingerprint data at the population level are used to infer evolutionary histories of species. Phylogeography above the species level is concerned with the genealogical aspects of divergent lineages. Here, we provide a phylogeographic study to examine the evolutionary history of a western Mediterranean composite,...
Article
Hybridization is known to have a creative role in plant evolution. However, it can also have negative effects on parental species. Onopordum is a large genus whose species frequently hybridize. In the Southwest Iberian Peninsula, the rare O. hinojense co-occurs with the widely distributed O. nervosum, and hybrids between these two taxa have been de...

Fifty nuclear microsatellite primers were initially developed using next-generation sequencing (454) data from a single individual of Tetraclinis articulata (Vahl) Mast. Eleven primers were finally applied in 30 individuals from 3 localities from Morocco, Algeria and Spain. The number of alleles per locus ranged from one to ten. The average observe...
Article
Andromonoecy (i.e. the occurrence on individual plants of hermaphroditic and male flowers) is a rare sexual system among the angiosperms, regarded by some authors as a transitional stage from hermaphroditism to monoecy. Having discovered the occurrence of andromonoecy in Erophaca baetica (a Mediterranean shrubby legume with two subspecies), a novel...
Article
Rumex bucephalophorus is a very polymorphic species that has been subjected to various taxonomic studies in which diverse infraspecific taxa have been recognised on the basis of diaspore traits. In this study we used molecular markers (ITS and AFLP) to explore this remarkable diversity, to test previous hypotheses of classification, and attempt to...
Article
The genus Erophaca comprises a single herbaceous perennial species with two subspecies distributed at opposite ends of the Mediterranean region. We used nrDNA ITS to investigate the phylogeny of the genus, and AFLP markers (9 primers, 20 populations) to establish the genetic relationship between subspecies, and among populations at each side of the...

Wild and domestic mammals were found to be the only effective dispersers of seeds, including those that currently do not share the same area of distribution. In contrast, birds rarely found the seeds appetizing and, additionally, destroyed them in their gizzard. Chamaerops humilis is one of the two native palms in Europe and the only one in wester...

Studying the spatial distribution of cytotypes and genome size in plants can provide valuable information about the evolution of polyploid complexes. Here, the spatial distribution of cytological races and the amount of DNA in Dianthus broteri, an Iberian carnation with several ploidy levels, is investigated. Sample chromosome counts and flow cytom...
Article
We used Amplified Fragment Length Polymorphism markers (AFLP) and breeding system studies to investigate the population structure and reproductive biology of Hypochaeris angustifolia (Asteraceae: Cichorieae). This species is endemic to altiplanos of the Atlas Mountains (Morocco) where it occurs in scattered populations, and it is the sister species...

We studied the relationships between self-incompatibility mechanisms and floral parameters in the genus Hypochaeris L. sect. Hypochaeris (consisting of H. glabra, H. radicata, H. arachnoidea, and H. salzmanniana). We assessed at intra- and interspecific levels (1) the self-incompatibility (SI) mechanism and its distribution among populations, (2) t...

The main aim of this proposal is to assess the plant biodiversity and ecological uniqueness of the Mediterranean heathland or herriza of the Strait of Gibraltar region, challenging the current view of considering it as the mere result of a contact of the Mediterranean garrigue with a 'remnant’ Atlantic heathland flora. Results will provide solid scientific ground for the conservation of this singular Mediterranean heathland-type vegetation
