Data from: Deconstructing heterostyly: the evolutionary role of incompatibility system, pollinators and floral architectureRocio Santos-Gally, Alejandro Gonzalez-Voyer & Juan Arroyo
Darwin’s early work on heterostyly and related style polymorphisms (the presence of two or three style morphs within a population) generated much interest to understand how precise interactions between ecological and genetic mechanisms influence the evolution of floral diversity. Here we tested three key hypotheses proposed to explain the evolution of heterostyly: i)the presence of self-incompatibility, ii) the role of pollinators in promoting dissasortative mating, and iii) floral architecture, which restricts pollinators’ movements and ensures...
Data from: Direct and indirect effects of global change on mycorrhizal associations of savanna plant communitiesIgnacio Manuel Pérez Ramos, Andrea Álvarez-Méndez, Katharina Wald, Luis Matías, María Dolores Hidalgo-Galvez & Carmen M. Navarro-Fernández
This data set contains a very detailed information on a field manipulative experiment of rainfall exclusion and increased temperature aimed to evaluate the impact of forecasted warming and drying on mycorrhizal associations of savanna plant communities subjected to different grazing history. Additionally, we compiled detailed information on the abiotic and biotic environment with the final aim of disentangling the direct and indirect effects of climate change on this widespread mycorrhizal symbiosis. Our results suggest that...

Dataset: Short Communication: A simple and accurate method of measuring the Zeta-Potential of microfluidic channelsRaul Fernandez-Mateo, Hywel Morgan, Victor Calero, Pablo Garcia-Sanchez & Antonio Ramos
This dataset supports the publication in Electrophoresis entitled 'Short Communication: A simple and accurate method of measuring the Zeta-Potential of microfluidic channels'. This is the original dataset used to create Figures 2B, 2C and Figure 3. It also contains the uncertainty estimations of the measured zeta potential displayed in Figure 3 computed from the original dataset for each of the conductivity solutions used in the work: 1.5 mS/m, 5.2 mS/m and 11.4 mS/m.
Polyploidy promotes divergent evolution across the leaf economics spectrum and plant edaphic niche in the Dianthus broteri complexJavier López-Jurado, Enrique Mateos-Naranjo & Francisco Balao
The evolution of the leaf economics spectrum (LES) is known to be constrained by genetic relatedness but also promoted at small geographic and phylogenetic scales. In those cases, we hypothesised that polyploidy would play a prominent role as an outstanding source of functional divergence and adaptive potential. We registered leaf-level nutrient, water and light economy related traits from the LES as well as edaphic properties in the four cytotypes of the autopolyploid Dianthus broteri complex...
Positive interactions between foundation species and their associated species are expected to be influenced by the degree of environmental stress as well as trait variations of the species involved. However, there is scarce empirical evidence regarding how these two factors interact and shape the intensity of facilitation. To test how facilitation varies with stress, a colonization experiment using artificial algal units that varied in a functional trait (morphological complexity) was conducted at different intertidal height...
Data from: Germination niche breadth of invasive Iris pseudacorus (L.) suggests continued recruitment from seeds with climate warmingBrenda J. Grewell, Morgane B. Gillard, Jesús M. Castillo, Mohsen B. Mesgaran & Caryn J. Futrell
Understanding recruitment processes of invasive species is central to conservation and management strategies. Iris pseudacorus,an emergent macrophyte, has established invasive populations across a broad global range where it reduces biodiversity in wetland ecosystems. Climate warming is altering cues that drive germination, yet studies on the invasion of wetland macrophytes often ignore germination ecology despite its importance to their establishment and spread. The dataset includes data generated from a series of experiments conducted to improve understanding...
1. Floral nectar harbours a diverse microbiome of yeasts and bacteria that depend predominantly on animal visitors for their dispersal. Since pollinators visit specific sets of flowers and carry their own unique microbiota, we hypothesize that plant species visited by the same set of pollinators may support non-random nectar microbial communities linked together by the type of pollinator. 2. Here we explore the importance of plant-pollinator interactions in the assembly of nectar microbiome and study...
Data from: High correlated paternity leads to negative effects on progeny performance in two mediterranean shrub speciesSofia Nora, Abelardo Aparicio & Rafael G. Albaladejo
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 pollen received by maternal plants (i.e. correlated paternity) has often been overlooked. In this study, we investigated the relation between correlated paternity and progeny performance in two common...
Epigenetic factors are increasingly being viewed as important mechanisms in organism performance. However, advances in plant epigenetics rely mostly on studies of short-lived model or cultivated species and there is a current gap in knowledge on wild plants, especially on woody plant species, that still needs to be addressed via empirical studies. Through a greenhouse experiment we compared the genetic (microsatellites) and epigenetic (methylation-sensitive amplified polymorphisms) variation in mother plants and their open-pollinated offspring of...
Data from: Long-tongued insects promote disassortative pollen transfer in style-dimorphic Narcissus papyraceus (Amaryllidaceae)Violeta I. Simón-Porcar, Rocío Santos-Gally & Juan Arroyo
1. In hermaphroditic flowers, reciprocal herkogamy e.g. heterostyly enhances pollen transfer between floral morphs (disassortative pollination) while avoiding self-interference between sexual organs. By contrast, disassortative pollination might be compromised in style-dimorphic flowers, which lack perfect reciprocity between the two floral morphs. This sub-optimal functioning has been considered to explain why stylar dimorphism is rare in nature. 2. Some style-polymorphic species receive a wide array of floral visitors, including long-tongued insects that feed on nectar and...
Data from: Genetic diversity of wild grapevine populations in Spain and their genetic relationships with cultivated grapevinesMaria T. De Andrés, Alejandro Benito, Gemma Pérez-Rivera, Rafael Ocete, María A. Lopez, Laura Gaforio, Gregorio Muñoz, Felix Cabello, José M. Martínez-Zapater & Rosa Arroyo-Garcia
The wild grapevine, Vitis vinifera L. ssp sylvestris (Gmelin) Hegi, considered as the ancestor of the cultivated grapevine, is native from Eurasia. In Spain natural populations of Vitis vinifera ssp sylvestris can still be found along river banks. In this work we have performed a wide search of wild grapevine populations in Spain and characterized the amount and distribution of their genetic diversity using 25 nuclear SSR loci. We have also analyzed the possible coexistence...
We studied the relationship between temperature and the coexistence of great tit Parus major and blue tit Cyanistes caeruleus, breeding in 75 study plots across Europe and North Africa. We expected an advance in laying date and a reduction in clutch size during warmer springs as a general response to climate warming and a delay in laying date and a reduction in clutch size during warmer winters due to density-dependent effects. As expected, as spring...
What drives diversification in a pantropical plant lineage with extraordinary capacity for long-distance dispersal and colonisation?Isabel Larridon, Javier Galán Díaz, Kenneth Bauters & Marcial Escudero
Aim: Colonisation of new areas may entail shifts in diversification rates linked to biogeographic movement (dispersification), which may involve niche evolution if species were not pre-adapted to the new environments. Scleria (Cyperaceae) includes c. 250 species and has a pantropical distribution suggesting an extraordinary capacity for long-distance dispersal and colonisation. We investigate patterns of diversification in Scleria, and whether they are coupled with colonisation events, climate niche shifts or both. Location: Tropics and subtropics. Taxon:...
Data from: Climate matching and anthropogenic factors contribute to the colonisation and extinction of local populations during avian invasionsLaura Cardador, José L Tella, Julie Louvrier, José D Anadón, Pedro Abellán & Martina Carrete
Concern about the impacts of biological invasions has generated a great deal of interest in understanding factors that determine invasion success. Most of our current knowledge comes from static approaches that use spatial patterns as a proxy of temporal processes. These approaches assume that species are present in areas where environmental conditions are the most favourable. However, this assumption is problematic when applied to dynamic processes such as species expansions when equilibrium has not been...

Data from: Disassortative mating prevails in style-dimorphic Narcissus papyraceus despite low reciprocity and compatibility of morphsVioleta Irene Simón-Porcar, Thomas R. Meagher & Juan Arroyo
Evolution to reduce inbreeding can favor disassortative (inter-morph) over assortative (intra-morph) mating in hermaphroditic sexually polymorphic plant species. Heterostyly enhances disassortative pollination through reciprocal placement of stigmas and anthers of morphs and appropriate pollinators. Stylar dimorphism in which there is not reciprocal anther placement may compromise disassortative mating, particularly when there is not intra-morph incompatibility. Variable rates of disassortative mating along with differential female fecundity or siring success among floral morphs could lead to variation...
Siempre que se aborda el problema de la enseñanza, su organización, sus resultados, su adecuación a las necesidades sociales, el currículum…, se termina fijando la mirada en una pieza clave: el profesorado. Y, sin duda, el profesorado es ese elemento clave del sistema, a través del cual pasa todo y sin el cual es impensable concebir el propio funcionamiento de la educación. Pero, más allá de las proclamaciones -o de las lamentaciones- en relación con...
Two new diploid species, Aira minoricensis and Aira hercynica are described and illustrated, along with chromosome counts, risk assessment, distribution and habitat, phenology, and comparisons with morphologically similar species. A comparative table and a key for the species of Aira for the Iberian Peninsula and the Balearic Islands are provided to assist in the identification of these overlooked species, and their relationships to other taxa are discussed.
Data from: Effects of interspecific coexistence on laying date and clutch size in two closely related species of hole‐nesting birdsAnders Pape Møller, Javier Balbontin, André A. Dhondt, Vladimir Remeš, Frank Adriaensen, Clotilde Biard, Jordi Camprodon, Mariusz Cichoń, Blandine Doligez, Anna Dubiec, Marcel Eens, Tapio Eeva, Anne E. Goodenough, Andrew G.

Nager, Jan-Åke Nilsson … & Ruedi G. Nager
Coexistence between great tits Parus major and blue tits Cyanistes caeruleus, but also other hole‐nesting taxa, constitutes a classic example of species co‐occurrence resulting in potential interference and exploitation competition for food and for breeding and roosting sites. However, the spatial and temporal variations in coexistence and its consequences for competition remain poorly understood. We used an extensive database on reproduction in nest boxes by great and blue tits based on 87 study plots across...
