Data from: From nature to the labratory: the impact of founder effects in adaptation

Josiane Santos, Marta Pascual, Pedro Simões, Inês Fragata, Margarida Lima, Bárbara Kellen, Marta Santos, Ana Marques, Michael R. Rose & Margarida Matos
Most founding events entail a reduction of population size, which in turn leads to genetic drift effects that can deplete alleles. Besides reducing neutral genetic variability, founder effects can in principle shift additive genetic variance for phenotypes that underlie fitness. This could then lead to different rates of adaptation among populations that have undergone a population size bottleneck as well as an environmental change, even when these populations have a common evolutionary history. Thus theory...

Data from: Landscape genetics highlights the role of bank vole metapopulation dynamics in the epidemiology of Puumala hantavirus

Emmanuel Guivier, Maxime Galan, Yannick Chaval, Anne Xuéreb, Alexis Ribas Salvador, Marie-Lazzarine Poulle, Liina Voutilainen, Heikki Henttonen, Nathalie Charbonnel & Jean François Cosson
Rodent host dynamics and dispersal are thought to be critical for hantavirus epidemiology as they determine pathogen persistence and transmission within and between host populations. We used landscape genetics to investigate how the population dynamics of the bank vole Myodes glareolus, the host of Puumala hantavirus (PUUV), vary with forest fragmentation and influence PUUV epidemiology. We sampled vole populations within the Ardennes, a French PUUV endemic area. We inferred demographic features such as population size,...

Data from: A pragmatic approach to the analysis of diets of generalist predators: the use of next-generation sequencing with no blocking probes

Josep Piñol, Victoria San Andrés, Elizabeth L. Clare, Gisela Mir & William O. C. Symondson
Predicting whether a predator is capable of affecting the dynamics of a prey species in the field implies the analysis of the complete diet of the predator, not simply rates of predation on a target taxon. Here, we employed the Ion Torrent next-generation sequencing technology to investigate the diet of a generalist arthropod predator. A complete dietary analysis requires the use of general primers, but these will also amplify the predator unless suppressed using a...

Data from: Gut microbiota dynamics during dietary shift in Eastern African cichlid fishes

Laura Baldo, Joan Lluís Riera, Ave Tooming-Klunderud, M. Mar Albà & Walter Salzburger
The gut microbiota structure reflects both a host phylogenetic history and a signature of adaptation to the host ecological, mainly trophic niches. African cichlid fishes, with their array of closely related species that underwent a rapid dietary niche radiation, offer a particularly interesting system to explore the relative contribution of these two factors in nature. Here we surveyed the host intra- and interspecific natural variation of the gut microbiota of five cichlid species from the...

Data from: Upstream analyses create problems with DNA-based species delimitation

Melisa Olave, Eduard Solà & L. Lacey Knowles
Genetic-based delimitation of species typically involves a multistep process in which DNA data are analyzed with a series of different programs. Although the performance of the programs associated with each step has been evaluated separately, no analysis has considered how errors in the upstream assignment of individuals to putative species impacts the accuracy of species delimited in downstream analyses, such as those associated with the coalescent-based Bayesian program bpp. Here we show that because the...

Data from: An antibody screen of a Plasmodium vivax antigen library identifies novel merozoite proteins associated with clinical protection

Camila T. França, Jessica B. Hostetler, Sumana Sharma, Michael T. White, Enmoore Lin, Benson Kiniboro, Andreea Waltmann, Andrew W. Darcy, Connie S. Li Wai Suen, Peter Siba, Christopher L. King, Julian C. Rayner, Rick M. Fairhurst, Ivo Mueller & Connie S. N. Li Wai Suen
Background. Elimination of Plasmodium vivax malaria would be greatly facilitated by the development of an effective vaccine. A comprehensive and systematic characterization of antibodies to P. vivax antigens in exposed populations is useful in guiding rational vaccine design. Methodology/Principal Findings. In this study, we investigated antibodies to a large library of P. vivax entire ectodomain merozoite proteins in 2 Asia-Pacific populations, analysing the relationship of antibody levels with markers of current and cumulative malaria exposure,...

Data from: Laboratory selection quickly erases historical differentiation

Inês Fragata, Pedro Simões, Miguel Lopes-Cunha, Margarida Lima, Bárbara Kellen, Margarida Bárbaro, Josiane Santos, Michael R. Rose, Mauro Santos & Margarida Matos
The roles of history, chance and selection have long been debated in evolutionary biology. Though uniform selection is expected to lead to convergent evolution between populations, contrasting histories and chance events might prevent them from attaining the same adaptive state, rendering evolution somewhat unpredictable. The predictability of evolution has been supported by several studies documenting repeatable adaptive radiations and convergence in both nature and laboratory. However, other studies suggest divergence among populations adapting to the...

Data from: Persistent natural acidification drives major distribution shifts in marine benthic ecosystems

Cristina Linares, Montserrat Vidal, Miquel Canals, Diego Kersting, David Amblas, Eneko Aspillaga, Emma Cebrian, Antonio Delgado-Huertas, David Diaz, Joaquim Garrabou, Bernat Hereu, Laura Navarro, Nuria Teixido & Enric Ballesteros
Ocean acidification is one of the main stressors affecting marine ecosystems. Rare CO2 vents offer a unique opportunity to investigate the response of benthic ecosystems to acidification. However, the benthic habitats that have been investigated so far are mainly very shallow water (≤5 m depth) and, therefore, to habitats that are poorly representative of the broad range of habitats that occur on the continental shelf. Here, we show that a decrease from pH 8.1 to...

Data from: Local pain dynamics during constant exhaustive exercise

Agnė Slapšinskaitė, Selen Razon, Natàlia Balagué, Robert Hristovski, Gershon Tenenbaum & Natàlia Balagué Serre
The purpose of this study was to delineate the topological dynamics of pain and discomfort during constant exercise performed until volitional exhaustion. Eleven physical education students were tested while cycling and running at a “hard” intensity level (e.g., corresponding to Borg’s RPE (6–20) = 15). During the tests, participants reported their discomfort and pain on a body map every 15s. “Time on task” for each participant was divided into five equal non-overlapping temporal windows within...

Data from: Microelastic mapping of the rat dentate gyrus

Tomas Luque, Michael S. Kang, David V. Schaffer & Sanjay Kumar
The lineage commitment of many cultured stem cells, including adult neural stem cells (NSCs), is strongly sensitive to the stiffness of the underlying extracellular matrix. However, it remains unclear how well the stiffness ranges explored in culture align with the microscale stiffness values stem cells actually encounter within their endogenous tissue niches. To address this question in the context of hippocampal NSCs, we used atomic force microscopy to spatially map the microscale elastic modulus (E)...

Data from: A geographical distribution database of the genus Dysdera in the Canary Islands (Araneae, Dysderidae)

Nuria Macías-Hernández, Salvador De La Cruz López, Marcos Roca-Cusachs, Pedro Oromí & Miquel A. Arnedo
The ground-dweller spider genus Dysdera shows very high species richness on the oceanic archipelago of the Canary Islands, providing one of the most outstanding examples of island radiation among spiders, only paralleled by Tetragnatha spiders on the Hawaiian archipelago. A georeferenced database of the 48 Dysdera species occurring in the Canary Islands was assembled to facilitate ongoing and future research on this remarkable lineage. All species are endemic to the archipelago except for the cosmopolitan...

Data from: Spatio-temporal monitoring of deep-sea communities using metabarcoding of sediment DNA and RNA

Magdalena Guardiola, Owen S. Wangensteen, Pierre Taberlet, Eric Coissac, María Jesús Uriz & Xavier Turon
We assessed spatio-temporal patterns of diversity in deep-sea sediment communities using metabarcoding. We chose a recently developed eukaryotic marker based on the v7 region of the 18S rRNA gene. Our study was performed in a submarine canyon and its adjacent slope in the Northwestern Mediterranean Sea, sampled along a depth gradient at two different seasons. We found a total of 5,569 molecular operational taxonomic units (MOTUs), dominated by Metazoa, Alveolata and Rhizaria. Among metazoans, Nematoda,...

Data from: Differentially expressed mRNA targets of differentially expressed miRNAs predict changes in the TP53 axis and carcinogenesis related pathways in human keratinocytes chronically exposed to arsenic

Laila Al-Eryani, Sabine Waigel, Ashish Tyagi, Jana Peremarti, Samantha F. Jenkins, Chendil Damodaran & J. Christopher States
Background: Arsenic is a widely distributed toxic natural element. Chronic arsenic ingestion causes several cancers, especially skin cancer. Arsenic-induced cancer mechanisms are not well defined, but several studies indicate that mutation is not the driving force and that microRNA expression changes play a role. Chronic low arsenite exposure malignantly transforms immortalized human keratinocytes (HaCaT), serving as a model for arsenic-induced skin carcinogenesis. Hypothesis: Early changes in miRNA expression in HaCaT cells chronically exposed to arsenite...

Data from: Resolving recent plant radiations: power and robustness of genotyping-by-sequencing

Mario Fernández-Mazuecos, Greg Mellers, Beatriz Vigalondo, Llorenç Sáez, Pablo Vargas & Beverley J. Glover
Disentangling species boundaries and phylogenetic relationships within recent evolutionary radiations is a challenge due to the poor morphological differentiation and low genetic divergence between species, frequently accompanied by phenotypic convergence, inter-specific gene flow and incomplete lineage sorting. Here we employed a genotyping-by-sequencing (GBS) approach, in combination with morphometric analyses, to investigate a small western Mediterranean clade in the flowering plant genus Linaria that radiated in the Quaternary. After confirming the morphological and genetic distinctness of...

Data from: Biodiversity in perennial and intermittent rivers: a meta-analysis

Maria Soria, Catherine Leigh, Thibault Datry, Luis Mauricio Bini & Nuria Bonada
Comprehensive knowledge of the effects of disturbances on biodiversity is crucial for conservation and management, not least because ecosystems with low biodiversity may be the most vulnerable. In rivers, the role of disturbance in shaping aquatic biodiversity has mainly focused on floods. Perennial rivers (PRs) often flood, whereas intermittent rivers (IRs) flood, stop flowing and dry. Despite the recent and significant increase in research on IRs, controversy remains about whether they are more or less...

Data from: Intraspecific genetic structure, divergence and high rates of clonality in an amphi-Atlantic starfish

Alex Garcia-Cisneros, Crue Palacín, Carlos Renato R. Ventura, Barbara Feital, Paulo C. Paiva & Rocio Perez Portela
Intraspecific genetic diversity and divergence have a large influence on the adaption and evolutionary potential of species. The widely distributed starfish, Coscinasterias tenuispina, combines sexual reproduction with asexual reproduction via fission. Here we analyse the phylogeography of this starfish to reveal historical and contemporary processes driving its intraspecific genetic divergence. We further consider whether asexual reproduction is the most important method of propagation throughout the distribution range of this species. Our study included 326 individuals...

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: 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: The grass was greener: repeated evolution of specialized morphologies and habitat shifts in ghost spiders following grassland expansion in South America

Fadia Sara Ceccarelli, Nicolas Mongiardino Koch, Eduardo M. Soto, Mariana L. Barone, Miquel A. Arnedo & Martin J. Ramirez
While grasslands, one of Earth’s major biomes, are known for their close evolutionary ties with ungulate grazers, these habitats are also paramount to the origins and diversification of other animals. Within the primarily South American spider subfamily Amaurobioidinae (Anyphaenidae), several species are found living in the continent’s grasslands, with some displaying putative morphological adaptations to dwelling unnoticed in the grass blades. Here, a dated molecular phylogeny provides the backbone for analyses revealing the ecological and...

Data from: Response diversity in Mediterranean coralligenous assemblages facing climate change: Insights from a multispecific thermotolerance experiment

Daniel Gómez Gras, Cristina Linares, Sonia De Caralt, Emma Cebrian, Maša Frleta-Valić, Ignasi Montero-Serra, Marta Pagès-Escolà, Paula López-Sendino & Joaquim Garrabou
Climate change threatens coastal benthic communities on a global scale. However, the potential effects of ongoing warming on mesophotic temperate reefs at the community level remain poorly understood. Investigating how different members of these communities will respond to the future expected environmental conditions is, therefore, key to anticipating their future trajectories and developing specific management and conservation strategies. Here, we examined the responses of some of the main components of the highly diverse Mediterranean coralligenous...

Data from: Elevational and microclimatic drivers of thermal tolerance in Andean Pristimantis frogs

Pol Pintanel, Miguel Tejedo, Santiago R. Ron, Gustavo A. Llorente & Andrés Merino-Viteri
Aim: We analysed elevational and microclimatic drivers of thermal tolerance diversity in a tropical mountain frog clade to test three macrophysiological predictions: less spatial variation in upper than lower thermal limits (Bretts’ heat invariant hypothesis); narrower thermal tolerance ranges in habitats with less variation in temperature (Janzen´s climatic variability hypothesis); and higher level of heat impacts at lower altitudes. Location: Forest and open habitats through a 4230 m elevational gradient across the tropical Andes of...

Rethinking megafauna

Marcos Moleón, José Sánchez-Zapata, José Donázar, Eloy Revilla, Berta Martín-López, Cayetano Gutiérrez-Cánovas, Wayne Getz, Zebensui Morales-Reyes, Ahimsa Campos-Arceiz, Larry Crowder, Mauro Galetti, Manuela González-Suárez, Fengzhi He, Pedro Jordano, Rebecca Lewison, Robin Naidoo, Norman Owen-Smith, Nuria Selva, Jens-Christian Svenning, José Tella, Christiane Zarfl, Sonja Jähnig, Matt Hayward, Søren Faurby, Nuria García … & Klement Tochner
Concern for megafauna is increasing among scientists and non-scientists. Many studies have emphasized that megafauna play prominent ecological roles and provide important ecosystem services to humanity. But, what precisely are “megafauna”? Here we critically assess the concept of megafauna and propose a goal-oriented framework for megafaunal research. First, we review definitions of megafauna and analyze associated terminology in the scientific literature. Second, we conduct a survey among ecologists and paleontologists to assess the species traits...

A framework for mapping the distribution of seabirds by integrating tracking, demography and phenology

Ana P. B. Carneiro, Elizabeth J. Pearmain, Steffen Oppel, Thomas A. Clay, Richard A. Phillips, Anne-Sophie Bonnet-Lebrun, Ross M. Wanless, Edward Abraham, Yvan Richard, Joel Rice, Jonathan Handley, Tammy E. Davies, Ben J. Dilley, Peter G. Ryan, Cleo Small, Javier Arata, John P. Y. Arnould, Elizabeth Bell, Leandro Bugoni, Letizia Campioni, Paulo Catry, Jaimie Cleeland, Lorna Deppe, Graeme Elliott, Amanda Freeman … & Maria P. Dias
1. The identification of geographic areas where the densities of animals are highest across their annual cycles is a crucial step in conservation planning. In marine environments, however, it can be particularly difficult to map the distribution of species, and the methods used are usually biased towards adults, neglecting the distribution of other life-history stages even though they can represent a substantial proportion of the total population. 2. Here we develop a methodological framework for...

Data from: Oceanic thermal structure mediates dive sequences in a foraging seabird

Xavier Meyer, Andrew MacIntosh, André Chiaradia, Akiko Kato, Francisco Ramírez, Cedric Sueur & Yan Ropert-Coudert
1. Changes in marine ecosystems are easier to detect in upper-level predators, like seabirds, which integrate trophic interactions throughout the food web. 2. Here, we examined whether diving parameters and complexity in the temporal organisation of foraging sequences of little penguins (Eudyptula minor) are influenced by sea surface temperature (SST), water stratification and wind speed – three oceanographic features influencing prey abundance and distribution in the water column. 3. Using fractal time series analysis, we...
