Article
Background and aims: The transition from outcrossing to selfing is a repeated pattern in angiosperm diversification and according to general theory this transition should occur quickly and mixed reproductive systems should be infrequent. However, a large proportion of flowering plants have mixed reproductive systems, even showing inbreeding depres...
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...

Hypochaeris leontodontoides is a rupicolous species endemic to the Atlas Mountains (Morocco), where it occurs in scattered populations. This study aims to understand the biogeographic structure of a high mountain species in a rather small area of NW Africa. We used Amplified Fragment Length Polymorphism (AFLP) to investigate the population structur...
Article
The increase in gene diversity from high to low latitudes is a widely recognized biogeographical pattern, often shaped by differential effects of Late Quaternary climatic changes. Here, we evaluate the effects of Pleistocene climatic changes from northern Europe to North Africa and their implications on the population differentiation of the widespr...
Article
Aims Habitat fragmentation impacts the spatial extent and isolation of local populations and communities. Although the biological consequences of these impacts have been well studied at the site level, effects directly related to changes in the spatial configuration of populations in the landscape remain less clear. The objective of this study is t...
Article
Fruit set is highly relevant to a plant's reproductive success. Fruit set can vary due to predation on flowers, pollinator services and/or resource availability. Reproductive success, measured as the fruit set of the invasive Lantana camara and the endemic Lantana peduncularis in the cool–dry season and the warm–wet season of the Galapagos Islands,...

Analyzing the pattern and causes of phenotypic and genetic variation within and among populations might help to understand life history variability in plants, and to predict their responses to changing environmental conditions. Here we compare phenotypic variation and genetic diversity of the widespread herb Plantago coronopus across Europe, and ev...
Article
In androdioecious metapopulations, where males co-occur with hermaphrodites, the absence of males from certain populations or regions may be explained by locally high selfing rates, high hermaphrodite outcross siring success (e.g. due to high pollen production by hermaphrodites), or to stochastic processes (e.g. the failure of males to invade popul...

1. Flower colour polymorphism is traditionally attributed to pollinator selection although other factors, such as indirect selection on correlated traits, can play an important role. 2. Lysimachia arvensis is a widespread annual species with two colour morphs differing in anthocyanin composition. We explored the hypothesis that colour polymorphism...
Article
In self-incompatible clonal plants, the spread of individual plants can exacerbate mate limitation to the point that it becomes a serious constraint on long-term population persistence, especially in small, isolated populations. In such species, it may be necessary to introduce new genetic material from other populations to restore seed production,...

Observations on birds feeding on fruits of the invasive shrub Lontana cámara (Supirrosa) were conducted on Santa Cruz Island, Galapagos (Ecuador) in the Dry Zone during the 2009 dry season. The endemic ground finches Geospiza magnirostris (Large Ground Finch) and G fortis (Medium Ground Finch) were recorded eating Lantana seeds with G. fortis the m...
Article
Low fruit set is common in many plant species and may be caused by a variety of factors, such as predation, resource limitation or deficient pollination, or it may be an evolutionary strategy. In this paper, we investigate factors that affect fruit set in Aristolochia baetica (Aristolochiaceae), a Mediterranean pipevine found in southwest Spain. Fr...
Article
Maternal effects are one of the most important influences on the offspring phenotype and their adaptive significance has been increasingly recognized. In this study we document the role of two sources of maternal effects, position and heterocarpy, on juvenile and adult traits of Rumex bucephalophorus, an annual plant that occurs in heterogeneous an...

Determining the sources of floral variation is crucial to the understanding of floral evolution. Architectural effects and phenotypic plasticity in development can play an important role in intraplant floral variation, giving rise to gender dimorphism or sexual specialization. Amphicarpic plants have another source of floral variation that could al...
Article
Aristolochia is the largest genus of the family Aristolochiaceae and the only one with large chromosome number variation. A combination of fluorochrome banding and in situ hybridization of 5S and 45S rDNA probes was used to evaluate the structural karyotype variability of representatives of two subgenera: Siphisia, which seems to have a single chro...
Article
The pollination of Aristolochia involves the temporary confinement of visitors inside the flower. A literature review has shown that some species are visited by one or a few dipteran families, while others are visited by a wider variety of dipterans, but only some of these are effective pollinators. We observed flowering phenology and temporal patt...

Project
In the 80´s Flora iberica Project started, under the coordination of Real Jardín Botánico de Madrid, and already are published 19 of the 21 planned volumes. Our group had collaborated steadily from 1985, and we participated in the edition of volumes IV in 1993, VII(I) in 1999, VII(II) in 2000, XVII in 2010 and XI in 2012, as well as the writing of numerous chapters in these and other volumes. The new phase X(2) is complementary to the Flora iberica X project (FLIB X), under coordination of Dr. Carlos Aedo (Jardín Botánico de Madrid), approved for the 2015-2017 period. The objectives of both projects are complemented with two principal tasks: 1) complete the elaboration, edition and publication of Compositae family (vol. XVI), planified in three parts, with the first one already published, and 2) complete the taxonomic study and the elaboration of manuscripts of the Gramineae genera assigned to the University of Seville (vol. XIX), which publication will be the final objective of the last phase of the project. The objectives of this project are coordinated with the three subprojects of FLIB X: Madrid (IP Dr. Carlos Aedo), Salamanca (IP Dr. Enrique Rico) y Córdoba (IP Dr. Juan Antonio Devesa), to assure designation of every task and avoid duplicity. Drafts of some chapters (in Spanish) are available in the website of "Gramina Iberica": https://sites.google.com/site/graminaiberica/
