Data from: New and Old World phylogeography of pumpkinseed (Lepomis gibbosus): the North American origin of introduced populations in Europe

Stan Yavno, Jenilee Gobin, Chris C Wilson, Anna Vila-Gispert, Gordon H Copp & Michael Fox
To determine the origin of introduced European populations of pumpkinseed (Lepomis gibbosus) – a freshwater sunfish, native to eastern North America that has spread across western and central Europe – we investigated the phylogeography of the species by sequencing the mitochondrial NADH subunit 1 gene. A total of 543 pumpkinseed were sampled from 32 sites across the native range of the species, and from 19 sites covering much of its introduced European range. The presence...

Environmental characteristics of the Mediterranean islands and the lizard assemblages

Daniel Escoriza
Aim: To identify and evaluate the environmental properties of the Mediterranean islands that make them a suitable habitat for their endemic lizards. This would represent an important improvement in our knowledge and would assist the conservation of these lizards, which are threatened by both the expansion of mainland species and the increasing intensity of human disturbance on these islands. Location: Mediterranean Basin. Methods: I assessed the environmental associations of 50 species of lizard (19 endemic)...

Data from: Identification and validation of single nucleotide polymorphisms as tools to detect hybridization and population structure in freshwater stingrays

Vanessa Paes Cruz, Manuel Vera, Belén Gomes Pardo, John Taggart, Paulino Martinez, Claudio Oliveira & Fausto Foresti
Single nucleotide polymorphism (SNP) markers were identified and validated for two stingrays species, Potamotrygon motoro and Potamotrygon falkneri, using double digest restriction-site associated DNA (ddRAD) reads using 454-Roche technology. A total of 226 774 reads (65.5 Mb) were obtained (mean read length 289 ± 183 bp) detecting a total of 5399 contigs (mean contig length: 396 ± 91 bp). Mining this data set, a panel of 143 in silico SNPs was selected. Eighty-two of these...

Heloise Gibb, Nathan J. Sanders, Robert R. Dunn, Simon Watson, Manoli Photakis, Silvia Abril, Alan N. Andersen, Elena Angulo, Inge Armbrecht, Xavier Arnan, Fabricio B. Baccaro, Tom R. Bishop, Raphael Boulay, Cristina Castracani, Israel Del Toro, Thibaut Delsinne, Mireia Diaz, David A. Donoso, Martha L. Enríquez, Tom M. Fayle, Donald H. Feener, Matthew C. Fitzpatrick, Crisanto Gómez, Donato A. Grasso, Sarah Groc … & C. Gomez
Many studies have focused on the impacts of climate change on biological assemblages, yet little is known about how climate interacts with other major anthropogenic influences on biodiversity, such as habitat disturbance. Using a unique global database of 1128 local ant assemblages, we examined whether climate mediates the effects of habitat disturbance on assemblage structure at a global scale. Species richness and evenness were associated positively with temperature, and negatively with disturbance. However, the interaction...

Marine biomonitoring with eDNA: can metabarcoding of water samples cut it as a tool for surveying benthic communities?

Adrià Antich, Cruz Palacín, Emma Cebrian, Owen Wangensteen, Raul Golo & Xavier Turon
In the marine realm, biomonitoring using eDNA of benthic communities requires destructive direct sampling or the setting-up of settlement structures. Comparatively much less effort is required to sample the water column, which can be accessed remotely. In this study we assess the feasibility of obtaining information from the eukaryotic benthic communities by sampling the adjacent water layer. We studied two different rocky-substrate benthic communities with a technique based on quadrat sampling. We also took replicate...

RNA-sequencing of endometrial explants

Sandra Recuero, José María Sánchez, Sandra Bagés-Arnal, Michael McDonald, Susanta K. Behura, Thomas E. Spencer, Marc Yeste, Pat Lonergan & Beatriz Fernandez-Fuertes
Seminal plasma (SP) has been shown to modulate the female reproductive environment in mammalian species in which the ejaculate comes into direct contact with the endometrium, such as mice, pigs and horses. In contrast, cattle ejaculate in the vagina, and it is questionable whether the fluid portion reaches the uterus. A recent study from our group reported that mating to intact, but not vasectomised, bulls modifies the endometrium transcriptome. However, it is not clear whether...

Energy limitation or sensitive predators? Trophic and non-trophic impacts of wastewater pollution on stream food webs

Jordi-René Mor, Isabel Muñoz, Sergi Sabater, Lluís Zamora & Albert Ruhi
Impacts of environmental stressors on food webs are often difficult to predict because trophic levels can respond in divergent ways, and biotic interactions may dampen or amplify responses. Here we studied food-web level impacts of urban wastewater pollution, a widespread source of degradation that can alter stream food webs via top-down and bottom-up processes. We selected ten pairs of sampling locations (i.e., twenty sites total) in ten small-to-medium tributaries of the Ebro River (NE Iberian...

Data from: Community-level flammability declines over 25 years of plant invasion in grasslands

Josep Padullés Cubino, Hannah L. Buckley, Nicola J. Day, Robin Pieper & Timothy J. Curran
1. Exotic plant invasions can alter fire regimes in plant communities. Invaders often possess traits that differ from native plants in the community, resulting in increases or declines in community-level flammability, changing fire regimes, and potentially causing long-term modifications to plant community composition. Although considering traits of multiple invaders and native species together is useful to better understand how invasions change community-level flammability, few studies have done this. 2 Measured morphological and flammability traits of...

Data from: Body reserves mediate trade-offs between life history traits: new insights from small pelagic fish reproduction

Pablo Brosset, Josep Lloret, Marta Muñoz, Christian Fauvel, Elisabeth Van Beveren, Virginie Marques, Jean-Marc Fromentin, Frédéric Ménard & Claire Saraux
Limited resources in the environment prevent individuals from simultaneously maximizing all life-history traits, resulting in trade-offs. In particular, the cost of reproduction is well known to negatively affect energy investment in growth and maintenance. Here, we investigated these trade-offs during contrasting periods of high versus low fish size and body condition (before/after 2008) in the Gulf of Lions. Female reproductive allocation and performance in anchovy (Engraulis encrasicolus) and sardine (Sardina pilchardus) were examined based on...

Data from: The peril of proportions: robust niche indices for categorical data

Michele E. R. Pierotti, Josep A. Martín-Fernández & Carles Barceló-Vidal
Indices of niche breadth and niche overlap for categorical data are typically expressed in terms of proportions of resources use. These are unit-sum constrained data; hence, direct application of standard general linear modelling methods to such indices can lead to spurious correlations and misleading inference. To overcome these limitations, we introduce a compositional data analysis (CoDA) approach and derive compositional expressions of niche breadth, niche overlap and specialization. Compositional data analysis is specifically devoted to...

Data from: Native drivers of fish life history traits are lost during the invasion process

Rodolphe Gozlan, Eva Zahorskae, Emira CHERIF, Takashi Asaeda, Robert Britton, Cha-Ho Chang, To Hong, Rafael Miranda, Jiri Musil, Meta Povz, Serhan Tarkan, Elena Tricarico, Tricia Trichkova, Hugo Verreycken, Andrej Weiperth, Andrej Witkowski, Lluis Zamora, Irene Zweimuller, Ya-Hui Zhao, Hamid Esmaeili & Marine Combe
Rapid adaptation to global change can counter vulnerability of species to population declines and extinction. Theoretically, under such circumstances both genetic variation and phenotypic plasticity can maintain population fitness, but empirical support for this is currently limited. Here, we aim to characterise the role of environmental and genetic diversity, and their prior evolutionary history (via haplogroup profiles) in shaping patterns of life history traits during biological invasion. Data were derived from both genetic and life...

RNA-sequencing endometrium intact, vasectomized, and control heifers

Sandra Recuero, José María Sánchez, Yentel Mateo-Otero, Sandra Bagés-Arnal, Michael McDonald, Susanta K Behura, Thomas E Spencer, David A Kenny, Marc Yeste, Pat Lonergan & Beatriz Fernandez-Fuertes
An appropriate female reproductive environment is essential for pregnancy success. In several species, including mice, pigs and horses, seminal plasma (SP) components have been shown to modulate this environment, leading to increased embryo viability and implantation. Due to the characteristics of mating in the aforementioned species, SP comes into direct contact with the uterus. However, it is questionable whether any SP reaches the uterus in species that ejaculate inside the vagina, such as humans and...

Natural selection favours drought escape and an acquisitive resource-use strategy in semiarid Mediterranean shrubs

Mario Blanco-Sánchez, Marina Ramos-Muñoz, Beatriz Pías, Jose Alberto Ramirez-Valiente, Laura Díaz-Guerra, Adrián Escudero & Silvia Matesanz
1. Natural selection is the major force driving adaptive evolution in natural populations, varying in strength, direction, and form through space and time, especially in highly variable environments such as Mediterranean ecosystems. Although a conservative resource-use strategy has been hypothesized to be adaptive in Mediterranean taxa, patterns of selection at the intraspecific level, i.e., the suite of traits determining individual fitness, are largely unknown. 2. Using a phenotypic selection experiment in natural semiarid conditions, we...

Organization of Squamata (Reptilia) assemblages in Mediterranean archipelagos

Daniel Escoriza
Mediterranean islands have complex reptile assemblages, but little is known about the factors that determine their organisation. In this study, the structure of assemblages of Squamata was evaluated based on their species richness and two measures of phylogenetic diversity (variability and clustering). I evaluated the composition of the assemblages comparing distinct biogeographic sub-regions within the Mediterranean: Adriatic, Aegean, Balearic, Corsica–Sardinia, Crete, Gulf of Gabés, Ionian Sea, Ligurian Sea, Malta, Sicily, and Tyrrhenian Sea. The effect...

Local-scale climatic refugia offer sanctuary for a habitat-forming species during a marine heatwave

Jana Verdura, Jorge Santamaría, Enric Ballesteros, Dan Smale, Maria Elena Cefalì, Raül Golo, Sònia De Caralt, Alba Vergés & Emma Cebrian
1. Gradual climate change and discrete extreme climatic events have driven shifts in the structure of populations and the distribution of species in many marine ecosystems. The most profound impacts of recent warming trends have been generally observed at species’ warm edges and on large conspicuous species. However, given that different species and populations exhibit different responses to warming, and that responses are highly variable at regional scales, there is a need to broaden the...

Modeled trajectories of the Mediterranean squamates

Daniel Escoriza
Mediterranean islands have a high diversity of squamates, although they are unevenly distributed. This variability in the composition of the reptile assemblages across islands may have been influenced by differences in the colonization abilities of these species. To evaluate the dispersal capacities of squamate species, we modeled their sea routes using cost surface models. We estimated the effects of some life-history traits and the phylogenetic signal in the characteristics of the modeled dispersal paths. We...

Data from: Warming impacts on early life stages increase the vulnerability and delay the population recovery of a long-lived habitat-forming macroalga

Pol Capdevila, Bernat Hereu, Roberto Salguero-Gómez, Graciel·La Rovira, Alba Medrano, Emma Cebrian, Joaquim Garrabou, Diego K. Kersting & Cristina Linares
1. Understanding the combined effects of global and local stressors is crucial for conservation and management, yet challenging due to the different scales at which these stressors operate. Here we examine the effects of one of the most pervasive threats to marine biodiversity, ocean warming, on the early life stages of the habitat-forming macroalga Cystoseira zosteroides, its long-term consequences for population resilience and its combined effect with physical stressors. 2. First, we performed a controlled...

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: Postglacial range expansion shaped the spatial genetic structure in a marine habitat-forming species: implications for conservation plans in the Eastern Adriatic Sea

Jean-Baptiste Ledoux, Maša Frleta-Valić, Silvija Kipson, Agostinho Antunes, Emma Cebrian, Cristina Linares, Pablo Sánchez, Raphael Leblois & Joaquim Garrabou
Aim: Understanding how historical and contemporary processes shaped and maintain spatial patterns of genetic diversity is a major goal for conservation biologists. Here, we characterized the pattern of neutral genetic diversity and we inferred underlying processes in the habitat-forming octocoral Paramuricea clavata in the Adriatic Sea, a peculiar phylogeographic region of the Mediterranean Sea. Location: Eastern coast of the Adriatic Sea. Methods: We genotyped seven microsatellites in 454 individuals of P. clavata from 13 populations...

Data from: Using text-mined trait data to test for cooperate-and-radiate co-evolution between ants and plants

Katrina M. Kaur, Pierre-Jean G. Male, Erik Spence, Crisanto Gomez & Megan E. Frederickson
Mutualisms may be “key innovations” that spur lineage diversification by augmenting niche breadth, geographic range, or population size, thereby increasing speciation rates or decreasing extinction rates. Whether mutualism accelerates diversification in both interacting lineages is an open question. Research suggests that plants that attract ant mutualists have higher diversification rates than non-ant associated lineages. We ask whether the reciprocal is true: does the interaction between ants and plants also accelerate diversification in ants, i.e. do...

Data from: Extending full protection inside existing marine protected areas or reducing fishing effort outside can reconcile conservation and fisheries goals

1. Most fish stocks worldwide are fished at maximum sustainable yield (MSY) or overfished, as many fisheries management strategies have failed to achieve sustainable fishing. Identifying effective fisheries management strategies has now become urgent. 2. Here, we developed a spatially-explicit metapopulation model accounting for population connectivity in the north-western Mediterranean Sea, and parameterized it for three ecologically and economically important coastal fish species: the white seabream Diplodus sargus, the two-banded seabream Diplodus vulgaris and the...

Data from: Genomic survey provides insights on the evolutionary changes during invasive European expansion of the mosquitofish (Gambusia holbrooki)

Manuel Vera, David Diez-Del-Molino & Jose Luis Garcia-Marin
Biological invasions rank among the main global threats for biodiversity. The Eastern mosquitofish (Gambusia holbrooki) is considered one of the 100 world worst invasive species due to its high adaptation capability to new environments. Using the restriction-site-associated DNA tags (RADtags), introduced European locations were compared against native US mosquitofish populations to analyse genomic changes that occurred during invasive process of European locations. After filtering, 7724 RADtags containing only one SNP were retained for population studies....

Data from: Habitat disturbance selects against both small and large species across varying climates

Heloise Gibb, Nathan J. Sanders, Robert R. Dunn, Xavier Arnan, Heraldo L. Vasconcellos, David A. Donoso, Alan N. Andersen, Rogerio R. Silva, Tom R. Bishop, Crisanto Gomez, Blair F. Grossman, Kalsum M. Yusah, Sarah H. Luke, Renata Pacheco, Jessica Pearce-Duvet, Javier Retana, Melanie Tista, Catherine L. Parr & H. L. Vasconcelos
Global extinction drivers, including habitat disturbance and climate change, are thought to affect larger species more than smaller species. However, it is unclear if such drivers interact to affect assemblage body size distributions. We asked how these two key global change drivers differentially affect the interspecific size distributions of ants, one of the most abundant and ubiquitous animal groups on earth. We also asked whether there is evidence of synergistic interactions and whether effects are...
