Data from: Inferring the demographic history of Drosophila subobscura from nucleotide variation at regions not affected by chromosomal inversions

Roser Pratdesaba, Carmen Segarra & Montserrat Aguadé
Drosophila subobscura presents a rich and complex chromosomal inversion polymorphism. It can thus be considered a model system i) to study the mechanisms originating inversions and how inversions affect the levels and patterns of variation in the inverted regions, and ii) to study adaptation at both the single-gene and chromosomal inversion levels. It is therefore important to infer its demographic history since previous information indicated that its nucleotide variation is not at mutation-drift equilibrium. For...

Data from: Strategies for understanding and reducing the Plasmodium vivax and Plasmodium ovale hypnozoite reservoir in Papua New Guinean children: a randomised placebo-controlled trial and mathematical model

Background: The undetectable hypnozoite reservoir for relapsing Plasmodium vivax and P. ovale malarias presents a major challenge for malaria control and elimination in endemic countries. This study aims to directly determine the contribution of relapses to the burden of P. vivax and P. ovale infection, illness, and transmission in Papua New Guinean children. Methods and Findings: From 17 August 2009 to 20 May 2010, 524 children aged 5–10 y from East Sepik Province in Papua...

Data from: Strategies of zooplanktivory shape dynamics and diversity of littoral plankton communities: a mesocosm approach

Laura K. Helenius, Anna Aymà Padros, Elina Leskinen, Hannu Lehtonen & Leena Nurminen
Planktivorous fish can exert strong top-down control on zooplankton communities. By incorporating different feeding strategies, from selective particulate feeding to cruising filter feeding, fish species target distinct prey. In this study, we investigated the effects of two species with different feeding strategies, the three-spined stickleback (Gasterosteus aculeatus (L.)) and roach (Rutilus rutilus (L.)), on a low-diversity brackish water zooplankton community using a 16-day mesocosm experiment. The experiment was conducted on a small-bodied spring zooplankton community...

Data from: Deep-sea, deep-sequencing: metabarcoding extracellular DNA from sediments of marine canyons

Magdalena Guardiola, María Jesús Uriz, Pierre Taberlet, Eric Coissac, Owen Simon Wangensteen & Xavier Turon
Marine sediments are home to one of the richest species pools on Earth, but logistics and a dearth of taxonomic work-force hinders the knowledge of their biodiversity. We characterized α- and β-diversity of deep-sea assemblages from submarine canyons in the western Mediterranean using an environmental DNA metabarcoding. We used a new primer set targeting a short eukaryotic 18S sequence (ca. 110 bp). We applied a protocol designed to obtain extractions enriched in extracellular DNA from...

Data from: Of niche differentiation, dispersal ability and historical legacies: what drives woody community assembly in recent Mediterranean forests?

Corina Basnou, Paloma Vicente, Josep Maria Espelta & Joan Pino
Community assembly rules have been extensively studied, but its association with regional environmental variation and land use history remains largely unexplored. Land use history might be especially important in Mediterranean forests, considering their historical deforestation and recent afforestation. Using forest inventories and historical (1956) and recent (2000) land cover maps, we explored the following hypotheses: 1) woody species assembly is driven by environmental factors, but also by historical landscape attributes; 2) recent forests exhibit lower...

Data from: Effects of the selective stretch-activated channel blocker GsMtx4 on stretch-induced changes in refractoriness in isolated rat hearts and on ventricular premature beats and arrhythmias after coronary occlusion in swine

José A. Barrabés, Javier Inserte, Luis Agulló, Antonio Rodríguez-Sinovas, Juan J. Alburquerque-Béjar & David Garcia-Dorado
Mechanical factors may contribute to ischemic ventricular arrhythmias. GsMtx4 peptide, a selective stretch-activated channel blocker, inhibits stretch-induced atrial arrhythmias. We aimed to assess whether GsMtx4 protects against ventricular ectopy and arrhythmias following coronary occlusion in swine. First, the effects of 170-nM GsMtx4 on the changes in the effective refractory period (ERP) induced by left ventricular (LV) dilatation were assessed in 8 isolated rat hearts. Then, 44 anesthetized, open-chest pigs subjected to 50-min left anterior descending...

Data from: The interplay among acorn abundance and rodent behavior drives the spatial pattern of seedling recruitment in mature Mediterranean oak forests

Pau Sunyer, Ester Boixadera, Alberto Muñoz, Raúl Bonal & Josep Maria Espelta
The patterns of seedling recruitment in animal-dispersed plants result from the interactions among environmental and behavioral variables. However, we know little on the contribution and combined effect of both kinds of variables. We designed a field study to assess the interplay between environment (vegetation structure, seed abundance, rodent abundance) and behavior (seed dispersal and predation by rodents, and rooting by wild boars), and their contribution to the spatial patterns of seedling recruitment in a Mediterranean...

Data from: Individual inversions or their combinations: which is the main selective target in a natural population of Drosophila subobscura?

Goran Zivanovic, Concepció Arenas & Francesc Mestres
It is generally accepted that chromosomal inversions have been key elements in adaptation and speciation processes. In this context, D. subobscura has been, and still is, an excellent model species due to its rich chromosomal polymorphism. In this species, many analyses from natural populations have demonstrated the adaptive potential of individual inversions (and their overlapped combinations, the so called arrangements). However, little information is available on the evolutionary role of combinations generated by inversions located...

To evaluate progress on political biodiversity objectives, biodiversity monitoring provides information on whether intended results are being achieved. Despite scientific proof that monitoring and evaluation increase the (cost) efficiency of policy measures, cost estimates for monitoring schemes are seldom available, hampering their inclusion in policy programme budgets. Empirical data collected from 12 case studies across Europe were used in a power analysis to estimate the number of farms that would need to be sampled per...

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: 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: Serum-free and xenobiotic-free preservation of cultured human limbal epithelial cells

Oeygunn A. Utheim, Rakibul Islam, Torstein Lyberg, Borghild Roald, Jon Roger Eidet, Maria Fideliz De La Paz, Darlene A. Dartt, Sten Raeder, Tor Paaske Utheim & Oeygunn Utheim
Aim/Purpose of the Study: To develop a one-week storage method, without serum and xenobiotics, that would maintain cell viability, morphology, and phenotype of cultured human limbal epithelial sheets. Materials and Methods: Human limbal explants were cultured on intact human amniotic membranes for two weeks. The sheets were stored in a hermetically sealed container at 23°C in either a serum-free medium with selected animal serum-derived compounds (Quantum 286) or a xenobiotic-free medium (Minimal Essential Medium) for...

Data from: Long telomeres are associated with clonality in wild populations of the fissiparous starfish Coscinasterias tenuispina

Alex Garcia-Cisneros, Rocío Pérez-Portela, Bethanie C. Almroth, Sofie Degerman, Creu Palacín & Helen Nilsson Sköld
TelTelomeres usually shorten during an organism’s lifespan and have thus been used as an aging and health marker. When telomeres become sufficiently short, senescence is induced. The most common method of restoring telomere length is via telomerase reverse transcriptase activity, highly expressed during embryogenesis. However, although asexual reproduction from adult tissues has an important role in the life cycles of certain species, its effect on the aging and fitness of wild populations, as well as...

Data from: Characterization of the transcriptome and gene expression of four different tissues in the ecologically relevant sea urchin Arbacia lixula using RNA-seq

R. Perez-Portela, X. Turon & A. Riesgo
The sea urchin Arbacia lixula is a keystone species in Mediterranean ecosystems that drive landscape changes in littoral communities. However, genomic information available for the whole order Arbacioida is very limited. Using RNA-seq techniques, we have characterized the transcriptome of four different tissue types in A. lixula: the ‘somatic’ tissues (coelomocytes and digestive tissue) and the ‘reproductive’ tissues (ovary and testis), from two replicated cDNA libraries for each sample. Additionally, we performed a de novo...

Data from: Locomotor mode and the evolution of the hindlimb in Western Mediterranean Anurans

Urtzi Enriquez-Urzelai, Albert Montori, Gustavo A. Llorente & Antigoni Kaliontzopoulou
The evolutionary association between morphology, locomotor performance and habitat use is a central element of the ecomorphological paradigm, and it is known to underlie the evolution of phenotypic diversity in numerous animal taxa. In anuran amphibians the hindlimb acts as the propulsive agent, and as such, it is directly associated with jumping performance. In this study we combine individual- and species-level analyses to examine the effects of locomotor mode on body size and hindlimb morphology...

Data from: Extant primitively segmented spiders have recently diversified from an ancient lineage

Xin Xu, Fengxiang Liu, Ren-Chung Cheng, Jian Chen, Xiang Xu, Zhisheng Zhang, Hirotsugu Ono, Dinh Sac Pham, Y. Norma-Rashid, Miquel A. Arnedo, Matjaž Kuntner, Daiqin Li & R.-C. Cheng
Living fossils are lineages that have retained plesiomorphic traits through long time periods. It is expected that such lineages have both originated and diversified long ago. Such expectations have recently been challenged in some textbook examples of living fossils, notably in extant cycads and coelacanths. Using a phylogenetic approach, we tested the patterns of the origin and diversification of liphistiid spiders, a clade of spiders considered to be living fossils due to their retention of...
