Data from: Genetic, morphological and acoustic evidence reveals lack of diversification in the colonization process in an island bird

Juan Carlos Illera, Ana M. Palmero, Paola Laiolo, Felipe Rodríguez, Ángel C. Moreno & Miguel Navascués
Songbirds with recently (i.e. early Holocene) founded populations are suitable models for studying incipient differentiation in oceanic islands. On such systems each colonization event represents a different evolutionary episode that can be studied by addressing sets of diverging phenotypic and genetic traits. We investigate the process of early differentiation in the spectacled warbler (Sylvia conspicillata) in 14 populations separated by sea barriers from three Atlantic archipelagos and from continental regions spanning from tropical to temperate...

Data from: Tropical rabbitfish and the deforestation of a warming temperate sea

Adriana Vergés, Fiona Tomas, Emma Cebrian, Enric Ballesteros, Zafer Kizilkaya, Panagiotis Dendrinos, Alexandros A. Karamanlidis, David Spiegel & Enric Sala
A striking example of climate-mediated range shifts in marine systems is the intrusion of tropical species into temperate areas worldwide, but we know very little about the ecological consequences of these range expansions. In the Mediterranean Sea, the range expansion of tropical rabbitfishes that first entered the basin via the Suez Canal provides a good example of how tropical herbivorous fish can impact the structure of rocky bottoms in temperate seas. Two species of rabbitfishes...

Data from: Marine communities on oil platforms in Gabon, West Africa: high biodiversity oases in a low biodiversity environment

Alan M. Friedlander, Enrique Ballesteros, John Michael Fay, Enric Sala & Michael Fay
The marine biodiversity of Gabon, West Africa has not been well studied and is largely unknown. Our examination of marine communities associated with oil platforms in Gabon is the first scientific investigation of these structures and highlights the unique ecosystems associated with them. A number of species previously unknown to Gabonese waters were recorded during our surveys on these platforms. Clear distinctions in benthic communities were observed between older, larger platforms in the north and...

Data from: Latitudinal environmental niches and riverine barriers shaped the phylogeography of the central Chilean endemic Dioscorea humilis (Dioscoreaceae)

Juan Viruel, Pilar Catalán & José Gabriel Segarra-Moragues
The effects of Pleistocene glaciations and geographical barriers on the phylogeographic patterns of lowland plant species in Mediterranean-climate areas of Central Chile are poorly understood. We used Dioscorea humilis (Dioscoreaceae), a dioecious geophyte extending 530 km from the Valparaíso to the Bío-Bío Regions, as a case study to disentangle the spatio-temporal evolution of populations in conjunction with latitudinal environmental changes since the Last Inter-Glacial (LIG) to the present. We used nuclear microsatellite loci, chloroplast (cpDNA)...

Data from: Local and regional founder effects in lake zooplankton persist after thousands of years despite high dispersal potential

Marc Ventura, Adam Petrusek, Alexandre Miró, Eva Hamrová, Danilo Buñay, Luc De Meester & Joachim Mergeay
We reconstructed the genetic structure of a planktonic crustacean Daphnia longispina living in high mountain lakes and ponds in the Pyrenees to investigate whether it was shaped by persistent founder effects originating shortly after the last glacial maximum or by ongoing dispersal and effective migration (gene flow). We found that the genetic structure can largely be explained by a single colonization event following gradual deglaciation of the Pyrenees c. 10-15 000 years ago. Nuclear genetic...

Data from: Bacteria and the evolution of honest signals. The case of ornamental throat feathers in spotless starlings

Magdalena Ruiz-Rodriguez, Gustavo Tomás, David Martín-Gálvez, Cristina Ruiz-Castellano & Juan Soler
1.Mechanisms guaranteeing reliability of messages are essential in understanding the underlying information and evolution of signals. Microorganisms may degrade signalling traits and therefore, influence the transmitted information and evolution of these characters. The role of microorganisms in animal signalling has, however, rarely been investigated. 2.Here, we explore a possible role for feather-degrading bacteria driving the design of ornamental throat feathers in male spotless starlings (Sturnus unicolor). We estimated length, bacterial load, degradation status, and susceptibility...

Data from: Mating portfolios: bet-hedging, sexual selection and female multiple mating

Francisco Garcia-Gonzalez, Jonathan P. Evans & Yukio Yasui
Polyandry (female multiple mating) has profound evolutionary and ecological implications. Despite considerable work devoted to understanding why females mate multiply, we currently lack convincing empirical evidence to explain the adaptive value of polyandry. Here, we provide a direct test of the controversial idea that bet-hedging functions as a risk-spreading strategy that yields multi-generational fitness benefits to polyandrous females. Unfortunately, testing this hypothesis is far from trivial, and the empirical comparison of the across-generations fitness payoffs...

Data from: Integration of conflict into integrative taxonomy: fitting hybridization in species delimitation of Mesocarabus (Coleoptera: Carabidae)

Carmelo Andújar, Paula Arribas, Carlos Ruiz, José Serrano & Jesús Gómez-Zurita
In species differentiation, characters do not usually diverge synchronously and there are also processes that effectively shuffle character states present in lineages descendant from a common ancestor. Species are thus expected to show some degree of incongruence among characters, and we argue that taxonomic delimitation actually benefits from integrative approaches and objective strategies dealing with character conflict. We illustrate the potential of exploiting conflict for species delimitation in a study-case of ground beetles of the...

Data from: Cuckoo hosts shift from accepting to rejecting parasitic eggs across their lifetime

Mercedes Molina-Morales, David Martín-Gálvez, Deborah A. Dawson, Terry A. Burke, Jesús Miguel Avilés & Juan Gabriel Martínez
One of the best known outcomes of coevolution between species is the rejection of mimetic parasite eggs by avian hosts, which has evolved to reduce costly cuckoo parasitism. How this behavioral adaptation varies along the life of individual hosts remains poorly understood. Here we identify for the first time, lifetime patterns of egg rejection in a parasitized long-lived bird, the magpie Pica pica and show that, during the years they were studied, some females accept,...

Data from: Signatures of volcanism and aridity in the evolution of an insular pine (Pinus canariensis Chr. Sm. Ex DC in Buch)

Unai López De Heredia, Rosana López, Carmen Collada, Brent C. Emerson & Luis Gil
Oceanic islands of volcanic origin provide useful templates for the study of evolution because they are subjected to recurrent perturbations that generate steep environmental gradients that may promote adaptation. Here we combine population genetic data from nuclear genes with the analysis of environmental variation and phenotypic data from common gardens to disentangle the confounding effects of demography and selection to identify the factors of importance for the evolution of the insular pine P. canariensis. Eight...

Data from: First insights into the transcriptome and development of new genomic tools of a widespread circum-Mediterranean tree species, Pinus halepensis Mill.

Sara Pinosio, Santiago C. González-Martínez, Francesca Bagnoli, Federica Cattonaro, Delphine Grivet, Fabio Marroni, Zaida Lorenzo, Juli G. Pausas, Miguel Verdú & Giovanni G. Vendramin
Pinus halepensis is a relevant conifer species for studying adaptive responses to drought and fire regimes in the Mediterranean region. Deciphering the molecular basis of Aleppo pine to the Mediterranean environment is therefore needed. In this study we performed Illumina next-generation sequencing of two phenotypically divergent Pinus halepensis accessions with the aims of i) characterizing the transcriptome through Illumina RNA-Seq of two accessions, phenotypically divergent for adaptive traits link to fire adaptation and drought, ii)...

Data from: Deciphering the adjustment between environment and life history in annuals: lessons from a geographically-explicit approach in Arabidopsis thaliana

Esperanza Manzano-Piedras, Arnald Marcer, Carlos Alonso-Blanco & F. Xavier Picó
The role that different life-history traits may have in the process of adaptation caused by divergent selection can be assessed by using extensive collections of geographically-explicit populations. This is because adaptive phenotypic variation shifts gradually across space as a result of the geographic patterns of variation in environmental selective pressures. Hence, large-scale experiments are needed to identify relevant adaptive life-history traits as well as their relationships with putative selective agents. We conducted a field experiment...

Data from: Medically important differences in snake venom composition are dictated by distinct postgenomic mechanisms

Nicholas R. Casewell, Simon C. Wagstaff, Wolfgang Wüster, Darren A. N. Cook, Fiona M. S. Bolton, Sarah I. King, Davinia Pla, Libia Sanz, Juan J. Calvete & Robert A. Harrison
Variation in venom composition is a ubiquitous phenomenon in snakes and occurs both interspecifically and intraspecifically. Venom variation can have severe outcomes for snakebite victims by rendering the specific antibodies found in antivenoms ineffective against heterologous toxins found in different venoms. The rapid evolutionary expansion of different toxin-encoding gene families in different snake lineages is widely perceived as the main cause of venom variation. However, this view is simplistic and disregards the understudied influence that...

Data from: Detecting slow introgression of invasive alleles in an extensively restocked game bird

Ines Sanchez-Donoso, Jisca Huisman, Jorge Echegaray, Manel Puigcerver, José Domingo Rodríguez-Teijeiro, Frank Hailer & Carles Vilà
Interbreeding of two species in the wild implies introgression of alleles from one species into the other only when admixed individuals survive and successfully backcross with the parental species. Consequently, estimating the proportion of first generation hybrids in a population may not inform about the evolutionary impact of hybridization. Samples obtained over a long time span may offer a more accurate view of the spreading of introgressed alleles in a species’ gene pool. Common quail...

Data from: Matrix composition and patch edges influence plant-herbivore interactions in marine landscapes

Jordi F. Pagès, Alessandro Gera, Javier Romero & Teresa Alcoverro
The functioning of ecosystems can be strongly driven by landscape attributes. Despite its importance, however, our understanding of how landscape influences ecosystem function derives mostly from species richness and abundance patterns, with few studies assessing how these relate to actual functional rates. We examined the influence of landscape attributes on the rates of herbivory in seagrass meadows, where herbivory has been identified as a key process structuring these relatively simple systems. The study was conducted...

Data from: Genetic component of flammability variation in a Mediterranean shrub

Bruno Moreira, Maria Clara Castellanos & Juli G. Pausas
Recurrent fires impose a strong selection pressure in many ecosystems worldwide. In such ecosystems, plant flammability is of paramount importance because it enhances population persistence, particularly in non-resprouting species. Indeed, there is evidence of phenotypic divergence of flammability under different fire regimes. Our general hypothesis is that flammability-enhancing traits are adaptive; here we test whether they have a genetic component. To test this hypothesis we used the post-fire obligate seeder Ulex parviflorus from sites historically...

Data from: Heritability of seed weight in Maritime pine, a relevant trait in the transmission of environmental maternal effects

Rafael Zas & Luis Sampedro
Quantitative seed provisioning is an important life-history trait with strong effects on offspring phenotype and fitness. As for any other trait, heritability estimates are vital for understanding its evolutionary dynamics. However, being a trait in between two generations, estimating additive genetic variation of seed provisioning requires complex quantitative genetic approaches for distinguishing between true genetic and environmental maternal effects. Here, using Maritime pine as a long-lived plant model, we quantified additive genetic variation of cone...

Data from: Cryptic habitats and cryptic diversity: unexpected patterns of connectivity and phylogeographic breaks in a Mediterranean endemic marine cave mysid

Pierre-Alexandre Rastorgueff, Pierre Chevaldonné, Defne Arslan, Caroline Verna & Christophe Lejeusne
The marine cave-dwelling mysid Hemimysis margalefi is distributed over the whole Mediterranean Sea which contrasts with the poor dispersal capabilities of this brooding species. In addition, underwater marine caves are a highly fragmented habitat which further promotes strong genetic structuring, therefore providing highly informative data on the levels of marine population connectivity across biogeographic regions. This study investigates how habitat and geography have shaped the connectivity network of this poor disperser over the entire Mediterranean...

Data from: Can facilitation influence the spatial genetics of the beneficiary plant population?

Maria Clara Castellanos, Santiago Donat-Caerols, Santiago C. González-Martínez & Miguel Verdú
Plant facilitation is a positive interaction where a nurse or nurse plant community alters the local conditions, improving the life-time fitness of other beneficiary plants. In stressful environments, a common consequence is the formation of discrete vegetation patches under nurse plants, surrounded by open space. The consequences of such spatial patterns have been studied mostly at the community level. At the population level, facilitation causes a distribution of beneficiary individuals that could have intra-specific genetic...

Data from: Host-parasite network structure is associated with community-level immunogenetic diversity

Shai Pilosof, Miguel A. Fortuna, Jean-François Cosson, Maxime Galan, Chaisiri Kittipong, Alexis Ribas, Eran Segal, Boris R. Krasnov, Serge Morand & Jordi Bascompte
Genes of the major histocompatibility complex (MHC) encode proteins that recognize foreign antigens and are thus crucial for immune response. In a population of a single host species, parasite-mediated selection drives MHC allelic diversity. However, in a community-wide context, species interactions may modulate selection regimes because the prevalence of a given parasite in a given host may depend on its prevalence in other hosts. By combining network analysis with immunogenetics, we show that host species...

Data from: Epigenetic variation predicts regional and local intraspecific functional diversity in a perennial herb

Mónica Medrano, Carlos M. Herrera & Pilar Bazaga
The ecological significance of epigenetic variation has been generally inferred from studies on model plants under artificial conditions, but the importance of epigenetic differences between individuals as a source of intraspecific diversity in natural plant populations remains essentially unknown. This paper investigates the relationship between epigenetic variation and functional plant diversity by conducting epigenetic (methylation-sensitive amplified fragment length polymorphisms, MSAP) and genetic (amplified fragment length polymorphisms, AFLP) marker-trait association analyses for 20 whole-plant, leaf and...

Data from: Population genetic structure of a sandstone specialist and a generalist heath species at two levels of sandstone patchiness across the Strait of Gibraltar

José-Gabriel Segarra-Moragues, Manuel Jesús Gil-López, Fernando Ojeda & José Gabriel Segarra-Moragues
Many habitat specialist species are originally composed of small, discontinuous populations because their habitats are naturally fragmented or patchy. They may have suffered the long-term effects of natural patchiness. Mediterranean heathlands, a representative habitat in the Strait of Gibraltar region, are associated with nutrient-poor, acidic sandstone soils. Sandstone soil patches in the African side of the Strait (Tangier) are, in general, smaller and more scattered than in the European side (Algeciras). In this study, we...

Data from: A phylogenetic perspective on species diversity, β-diversity, and biogeography for the microbial world

Albert Barberán & Emilio Casamayor
There is an increasing interest to combine phylogenetic data with distributional and ecological records to assess how natural communities arrange under an evolutionary perspective. In the microbial world there is also a need to go beyond the problematic species definition to deeply explore ecological patterns using genetic data. We explored links between evolution/phylogeny and community ecology using bacterial 16S rRNA gene information from a high altitude lakes district dataset to describe phylogenetic community composition, spatial...
