En la descripción original de Helianthemum mathezii se considera esta especie como un terofito. Sin embargo, la observación minuciosa de su holotipo, así como de otros especímenes recientemente recolectados en la misma localidad del tipo, sugiere que no se trata de una planta anual. Concluimos que estas plantas pueden ser bien identificadas...

Anthropogenic habitat deterioration can promote changes in plant mating systems that subsequently may affect progeny performance, thereby conditioning plant recruitment for the next generation. However, very few studies yet tested mating system parameters other than outcrossing rates; and the direct effects of the genetic diversity of the...

Analysing pollen movement is a key to understanding the reproductive system of plant species and how it is influenced by the spatial distribution of potential mating partners in fragmented populations. Here we infer parameters related to levels of pollen movement and diversity of the effective pollen cloud for the wind-pollinated shrub Pistacia...

El lentisco (Pistacia lentiscus L., Anacardiaceae) es uno de los arbustos más abundantes y característicos de la cuenca Mediterránea. Sus frutos, tipo drupa, son el principal reclamo y fuente alimenticia de los frugívoros invernantes de esta región estableciendo una interacción muy importante planta-animal, pero el cambio del uso del suelo y la...

Molecular systematics requires the establishment of a robust phylogenetic framework including extensive geographical and taxonom-ic sampling. In this work, we proposed systematic changes in the genus Helianthemum based on phylogenetic trees obtained by both maximum likelihood and Bayesian analyses of GBS data. The implications of these...

The mechanisms underlying heterozygosity-fitness correlations (HFCs) are subject of intense debates, especially about how important population features such as size or degree of isolation influence HFCs. Here, we report variation in HFCs between Large and Small populations of a self-compatible shrub (Myrtus communis) occurring within an...

En este trabajo presentamos una hipótesis filogenética para el género Helianthemum en la Península Ibérica. Para ello hemos recolectado en el campo material de todos los taxones y analizado las secuencias del marcador nuclear ITS (internal transcribed spacer) completo (ITS1+5.8S+ITS2) tanto con métodos Bayesianos como de Máxima Verosimilitud....

El estudio de la epigenética, cambios químicos estables que no suponen cambios en la secuencia de nucleótidos, ha avanzado considerablemente en los últimos años. Estos cambios son modulables por el ambiente, y pueden ser heredados por las generaciones siguientes. Hay una creciente evidencia de que la variación hereditaria en los rasgos...

Spatial patterns of genetic variation provide information central to many ecological, evolutionary, and conservation questions. This spatial variability has traditionally been analyzed through summary statistics between pairs of populations, therefore missing the simultaneous influence of all populations. More recently, a network approach has...

The region around the Strait of Gibraltar is considered to be one of the most relevant 'hot spots' of biodiversity in the Mediterranean Basin due to its historical, biogeographical, and ecological features. Prominent among these is its role as a land bridge for the migration and differentiation of species during the Pleistocene, as a...

The biogeographic history and the degree of environmental niche conservatism provide essential clues to decipher the underlying macroevolutionary processes of species diversification and to understand contemporary patterns of biodiversity. The genus Helianthemum constitutes an excellent case study to investigate the impact of the geo-climatic...
