Desentrañando la historia y evolución en el principal «hotspot» de biodiversidad vegetal ibérica. Una aproximación multiescalar en el Parque Nacional de Sierra Nevada
(Organismo Autónomo Parques Nacionales (OAPN), 2017)
Dadas las amenazas actuales sobre la biodiversidad del planeta, es crítico desentrañar los mecanismos evolutivos responsables de la formación de los puntos calientes de biodiversidad («hotspots»). Sierra Nevada es un ...

Genetic diversity and differentiation in narrow versus widespread taxa of Helianthemum (Cistaceae) in a hotspot: The role of geographic range, habitat, and reproductive traits
(John Wiley & Sons Ltd, 2019)
Unraveling the relationships between ecological, functional traits and genetic diversity of narrow endemic plants provide opportunities for understanding how evolutionary processes operate over local spatial scales and ...

Disassortative mating prevails in style-dimorphic Narcissus papyraceus despite low reciprocity and compatibility of morphs
(Society for the Study of Evolution, 2015-09-01)
Evolution to reduce inbreeding can favor disassortative (intermorph) over assortative (intramorph) mating in hermaphroditic sexually polymorphic plant species. Heterostyly enhances disassortative pollination through ...

Plant diversity patterns across scales in a Mediterranean biodiversity hotspot the interface between ecology and history in the Baetic-Rifan range
(2014)
The evolutionary and ecological processes that shape species diversity shift as spatial and temporal scales change and diversity patterns in assemblages may thus reflect these shifts. In this PhD Thesis, I explore taxonomic, ...

Selection on tropane alkaloids in native and non‐native populations of Datura stramonium
(Wiley, 2019)
heories of plant invasion based on enemy release in a new range assume that selection exerted by specialist herbivores on defence traits should be reduced, absent, or even selected against in the new environment. Here, we ...

Contrasting heterozygosity-fitness correlations between populations of a self-compatible shrub in a fragmented landscape
(Springer Nature, 2012)
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 ...

El papel de los polinizadores en la evolución floral: una perspectiva mediterránea
(Asociacion Espanola de Ecologia Terrestre, 2018)
Los polinizadores son un determinante clave en la evolución floral a escala global. En el ámbito mediterráneo, son muchos los ejemplos de su papel en poblaciones de plantas de nuestra flora. A nivel macroevolutivo o de ...

Evolución y función de la heterostilia en el género Linum (Linaceae).
(2017-12-20)
El género Linum L., que comprende alrededor de 180 especies (The Plant List 2013, Version 1. http://www.theplantlist.org/ último acceso el 10 de Marzo de 2017) y con una distribución cosmopolita, ha sido históricamente ...

Morph ratio variation and sex organ reciprocity in style-dimorphic Narcissus assoanus
(University of Chicago, 2012-10)
The maintenance of floral polymorphisms depends on rates and efficiency of cross-pollination within and among mating types in relation to their relative frequency. Here, we examine whether stigma-anther reciprocity in ...
