Albert Lecube, Enric Sánchez, Fernando Gómez-Peralta, Cristina Abreu, Joan Valls, Olga Mestre, Odile Romero, María Dolores Martínez, Gabriel Sampol, Andreea Ciudin, Cristina Hernández & Rafael Simó
Type 2 diabetes (T2D) is an independent risk factor for sleep breathing disorders. However, it is unknown whether T2D affects daily somnolence and quality of sleep independently of the impairment of polysomnographic parameters. Material and Methods: A case-control study including 413 patients with T2D and 413 non-diabetic subjects, matched by age, gender, BMI, and waist and neck circumferences. A polysomnography was performed and daytime sleepiness was evaluated using the Epworth Sleepiness Scale (ESS). In addition,...

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: Phenotypic biomarkers of climatic impacts on declining insect populations: a key role for decadal drought, thermal buffering and amplification effects and host plant dynamics

Jofre Carnicer, Constantí Stefanescu, Maria Vives-Ingla, Carlos López, Sofia Cortizas, Christopher Wheat, Roger Vila, Joan Llusià & Josep Penuelas
1. Widespread population declines have been reported for diverse Mediterranean butterflies over the last three decades, and have been significantly associated to increased global change impacts. The specific landscape and climatic drivers of these declines remain uncertain for most declining species. 2. Here we analyse whether plastic phenotypic traits of a model butterfly species (Pieris napi) perform as reliable biomarkers of vulnerability to extreme temperature impacts in natural populations, showing contrasting trends in thermally exposed...

Data from: Reproductive strategies and isolation-by-demography in a marine clonal plant along an eutrophication gradient

Silvia Oliva, Javier Romero, Marta Pérez, Pablo Manent, Oriol Mascaró, Ester A. Serrão, Nelson Coelho & Filipe Alberto
Genetic diversity in clonal organisms includes two distinct components, 1) the diversity of genotypes or clones (i.e., genotypic richness) in a population, and 2) that of the alleles (i.e., allelic and gene diversity within populations, and differentiation between populations). We investigated how population differentiation and genotypic components are associated across a gradient of eutrophication in a clonal marine plant. To that end we combined direct measurements of sexual allocation (i.e., flower and seed counts) and...

Data from: Dancing together and separate again: gymnosperms exhibit frequent changes of fundamental 5S and 35S rRNA genes (rDNA) organisation

Ales Kovařík & Sonia Garcia
In higher eukaryotes, the 5S rRNA genes occur in tandem units and are arranged either separately (S-type arrangement) or linked to other repeated genes, in most cases to rDNA locus encoding 18S–5.8S–26S genes (L-type arrangement). Here we used Southern blot hybridisation, PCR and sequencing approaches to analyse genomic organisation of rRNA genes in all large gymnosperm groups, including Coniferales, Ginkgoales, Gnetales and Cycadales. The data are provided for 27 species (21 genera). The 5S units...

Data from: The complex relationship of exposure to new Plasmodium infections and incidence of clinical malaria in Papua New Guinea

Natalie E. Hofmann, Stephan Karl, Rahel Wampfler, Benson Kiniboro, Albina Teliki, Jonah Iga, Andreea Waltmann, Inoni Betuela, Ingrid Felger, Leanne J. Robinson & Ivo Mueller
The molecular force of blood-stage infection (molFOB) is a quantitative surrogate metric for malaria transmission at population level and for exposure at individual level. Relationships between molFOB, parasite prevalence and clinical incidence were assessed in a treatment-to-reinfection cohort, where P.vivax (Pv) hypnozoites were eliminated in half the children by primaquine (PQ). Discounting relapses, children acquired equal numbers of new P. falciparum (Pf) and Pv blood-stage infections/year (Pf-molFOB=0-18, Pv-molFOB=0-23) resulting in comparable spatial and temporal patterns...

Data from: Molecular phylogeny of unikonts: new insights into the position of apusomonads and ancyromonads and the internal relationships of Opisthokontsí

Jordi Paps, Luis A. Medina-Chacón, Wyth Marshall, Hiroshi Suga & Iñaki Ruiz-Trillo
The eukaryotic supergroup known as the Opisthokonta includes animals (Metazoa), fungi, choanoflagellates, as well as some poorly-studied unicellular eukaryotes, such as the Nucleariidea, Fonticula alba, the Ichthyosporea, the Filasterea and Corallochytrium limacisporum. Whereas the evolutionary positions of the well-known opisthokont lineages are mostly resolved, the specific phylogenetic relationships among those neglected opisthokont lineages is unsettled. Moreover, it remains unclear whether Amoebozoa or Apusozoa are the sister group to opisthokonts. Aiming at elucidating the evolutionary tree...

Data from: Molecular phylogenetics of Gobioidei and phylogenetic placement of European gobies

Ainhoa Agorreta, Diego San Mauro, Ulrich Schliewen, James L. Van Tassell, Marcelo Kovačić, Rafael Zardoya & Lukas Rüber
Gobioidei is one of the largest suborders of teleost fishes, with nearly 2000 extant species currently recognized. They have a worldwide distribution and show a spectacular variety in morphology, ecology, and behavior. Despite their importance, phylogenetic relationships among many groups of gobioids (including some of the major lineages) still remain poorly understood. In this study, we analyze sequence data of five molecular markers (two mitochondrial and three nuclear) averaging 6000 bp for 222 species of...

Data from: Abrupt changes in the composition and function of fungal communities along an environmental gradient in the High Arctic

Grau Oriol, Jozsef Geml, Aaron Pérez-Haase, Josep M. Ninot, Tatiana A. Semenova-Nelsen, Josep Peñuelas & Oriol Grau
Fungi play a key role in soil-plant interactions, nutrient cycling, and carbon flow and are essential for the functioning of arctic terrestrial ecosystems. Some studies have shown that the composition of fungal communities is highly sensitive to variations in environmental conditions, but little is known about how the conditions control the role of fungal communities (i.e. their ecosystem function). We used DNA metabarcoding to compare taxonomic and functional composition of fungal communities along a gradient...

Data from: Estimation of inhalation flow profile using audio-based methods to assess inhaler medication adherence

Terence E. Taylor, Helena Lacalle Muls, Richard W. Costello & Richard B. Reilly
Asthma and chronic obstructive pulmonary disease (COPD) patients are required to inhale forcefully and deeply to receive medication when using a dry powder inhaler (DPI). There is a clinical need to objectively monitor the inhalation flow profile of DPIs in order to remotely monitor patient inhalation technique. Audio-based methods have been previously employed to accurately estimate flow parameters such as the peak inspiratory flow rate of inhalations, however, these methods required multiple calibration inhalation audio...

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: Generation and maintenance of predation hotspots of a functionally important herbivore in a patchy habitat mosaic

Simone Farina, Aitana Oltra, Jordi Boada, Frederic Bartumeus, Javier Romero & Teresa Alcoverro
1. By modifying how critical ecosystem functions are distributed across the landscape, the spatial configuration and characteristics of patches can play a strong role in structuring communities. In strongly predator-controlled ecosystems, this patchy distribution of function can have complex downstream consequences, subjecting some areas to disproportionately high rates of predation, leaving other areas susceptible to herbivore outbreaks. 2. In this study we assess how spatial attributes at patch and landscape scales potentially influence the spatial...

Data from: Strong linkages between depth, longevity and demographic stability across marine sessile species

Ignasi Montero-Serra, Cristina Linares, Daniel F. Doak, Jean-Baptiste Ledoux & Joaquim Garrabou
Understanding the role of the environment in shaping the evolution of life histories remains a major challenge in ecology and evolution. We synthesize longevity patterns of marine sessile species and find strong positive relationships between depth and maximum lifespan across multiple sessile marine taxa, including corals, bivalves, sponges and macroalgae. Using long-term demographic data on marine sessile and terrestrial plant species, we show that extreme longevity leads to strongly dampened population dynamics. We also used...

Data from: From global to local genetic structuring in the red gorgonian Paramuricea clavata: the interplay between oceanographic conditions and limited larval dispersal

Kenza Mokhtar-Jamaï, Marta Pascual, Jean-Baptiste Ledoux, Rafel Coma, Jean-Pierre Féral, Joaquim Garrabou & Didier Aurelle
Defining the scale of connectivity among marine populations and identifying the barriers to gene flow are tasks of fundamental importance for understanding the genetic structure of populations and for the design of marine reserves. Here we investigated the population genetic structure at three spatial scales of the red gorgonian Paramuricea clavata (Cnidaria, Octocorallia) a key species dwelling in the coralligenous assemblages of the Mediterranean Sea. Colonies of P. clavata were collected from 39 locations across...

Data from: Breaking out of the comfort zone: El Niño-Southern Oscillation as a driver of trophic flows in a benthic consumer of the Humboldt Current ecosystem

José M. Riascos, Marco A. Solís, Aldo S. Pacheco & Manuel Ballesteros
The trophic flow of a species is considered a characteristic trait reflecting its trophic position and function in the ecosystem and its interaction with the environment. However, climate patterns are changing and we ignore how patterns of trophic flow are being affected. In the Humboldt Current ecosystem, arguably one of the most productive marine systems, El Niño-Southern Oscillation is the main source of interannual and longer-term variability. To assess the effect of this variability on...

Data from: Interpreting ELISA analyses from wild animal samples: some recurrent issues and solutions

Romain Garnier, Raül Ramos, Ana Sanz-Aguilar, Maud Poisbleau, Henri Weimerskirch, Sarah Burthe, Jeremy Tornos & Thierry Boulinier
1. Many studies in disease and immunological ecology rely on the use of assays that quantify the amount of specific antibodies (immunoglobulin) in samples. Enzyme-Linked Immuno Sorbent Assays (ELISAs) are increasingly used in ecology due to their availability for a broad array of antigens and the limited amount of sampling material they require. Two recurrent methodological issues are nevertheless faced by researchers: (i) the limited availability of immunological assays and reagents developed for non-model species,...

Data from: Tracking changes in chromosomal arrangements and their genetic content during adaptation

Josiane Santos, Marta Pascual, Inês Fragata, Pedro Simões, Marta A. Santos, Margarida Lima, Ana Marques, Miguel Lopes-Cunha, Bárbara Kellen, Joan Balanyà, Michael R. Rose & Margarida Matos
There is considerable evidence for an adaptive role of inversions, but how their genetic content evolves and affects the subsequent evolution of chromosomal polymorphism remains controversial. Here, we track how life-history traits, chromosomal arrangements and 22 microsatellites, within and outside inversions, change in three replicated populations of Drosophila subobscura for 30 generations of laboratory evolution since founding from the wild. The dynamics of fitness-related traits indicated adaptation to the new environment concomitant with directional evolution...

Data from: Effect of oceanographic barriers and overfishing on the population genetic structure of the European spiny lobster (Palinurus elephas)

Ferran Palero, Pere Abelló, Enrique Macpherson, Mark Beaumont & Marta Pascual
Defining population structure and genetic diversity levels is of the utmost importance for developing efficient conservation strategies. Overfishing has caused mean annual catches of the European spiny lobster (Palinurus elephas) to decrease alarmingly along its distribution area. In this context, there is a need for comprehensive studies to evaluate the genetic health of the exploited populations. The present work is based on a set of 10 nuclear markers amplified in 331 individuals from 10 different...

Data from: QuantiFERON®-TB Gold In-Tube for contact screening in BCG-vaccinated adults: a longitudinal cohort study

Laura Muñoz, Lucía Gonzalez, Laura Soldevila, Jordi Dorca, Fernando Alcaide & Miguel Santin
Objective. To assess the utility of QuantiFERON®-TB Gold In-tube (QFT-GIT) for targeting preventive therapy in BCG-vaccinated contacts of tuberculosis (TB), based on its high specificity and negative predictive value for development of TB. Methods. We compared two screening strategies for TB contact tracing in two consecutive periods: the tuberculin skin test (TST) period, when all contacts were screened with the TST alone; and the QFT-GIT period, when BCG-vaccinated contacts underwent TST and QFT-GIT. Diagnosis of...

Data from: The leaf economic and plant size spectra of European forest understory vegetation

Josep Padullés Cubino, Idoia Biurrun, Gianmaria Bonari, Tatiana Braslavskaya, Xavier Font, Ute Jandt, Florian Jansen, Valerijus Rašomavičius, Wolfgang Willner & Milan Chytrý
Forest understories play a vital role in ecosystem functioning and the provision of ecosystem services. However, the extent to which environmental conditions drive dominant ecological strategies in forest understories at the continental scale remains understudied. Here, we used ~29,500 forest vegetation plots sampled across Europe and classified into 25 forest types to explore the relative role of macroclimate, soil pH, and tree canopy cover in driving abundance-weighted patterns in the leaf economic spectrum (LES) and...

Data from: Drought legacies are short, prevail in dry conifer forests and depend on growth variability.

Antonio Gazol, J. Julio Camarero, Raúl Sánchez-Salguero, Sergio Vicente-Serrano, Xavier Serra-Maluquer, Emilia Gutiérrez, Martín De Luis, Gabriel Sangüesa-Barreda, Klemen Novak, Vicente Rozas, Pedro A. Tiscar, Juan C. Linares, Edurne Martínez Del Castillo, Montse Ribas, Ignacio García-González, Fernando Silla, Álvaro Camisón, Mar Genova, Jose Miguel Olano, Ana-Maria Hereș, Jorge Curiel-Yuste, Luis A. Longares, Andrea Hevia, Miquel Tomas-Burguera & Juan Galván
The negative impacts of drought on forest growth and productivity last for several years generating legacies, although the factors that determine why such legacies vary across sites and tree species remain unclear. We used an extensive network of tree-ring width (RWI, ring-width index) records of 16 tree species from 567 forests, and high-resolution climate and NDVI datasets across Spain during the common period 1982‒2008 to test the hypothesis that climate conditions and growth features modulate...

Data from: Testing macroecological abundance patterns: the relationship between local abundance and range size, range position and climatic suitability among European vascular plants

Maria Sporbert, Petr Keil, Gunnar Seidler, Helge Bruelheide, Ute Jandt, Svetlana Aćić, Idoia Biurrun, Juan Antonio Campos, Andraž Čarni, Milan Chytrý, Renata Custerevska, Jürgen Dengler, Valentin Golub, Florian Jansen, Anna Kuzemko, Jonathan Lenoir, Corrado Marcenò, Jesper Erenskjold Moeslund, Aaron Pérez-Haase, Solvita Rūsiņa, Urban Šilc, Ioannis Tsiripidis, Vigdis Vandvik, Kiril Vassilev, Risto Virtanen … & Erik Welk
Aim: A fundamental question in macroecology centres around understanding the relationship between species’ local abundance and their distribution in geographic and climatic space (i.e. the multi-dimensional climatic space or climatic niche). Here, we tested three macroecological hypotheses that link local abundance to the following range properties: (1) the abundance-range size relationship, (2) the abundance-range centre relationship, and (3) the abundance-suitability relationship. Location: Europe Taxon: Vascular plants Methods: Distribution range maps were extracted from the Chorological...

Epiphytic diatom community structure and richness is determined by macroalgal host and location in the South Shetland Islands (Antarctica)

Andrea Burfeid-Castellanos, Rafael P. Martín-Martín, Michael Kloster, Carlos Angulo-Preckler, Conxita Avila & Bánk Beszteri
The marine waters around the South Shetland Islands are paramount in the primary production of this Antarctic ecosystem. With the increasing effects of climate change and the annual retreat of the ice shelf, the importance of macroalgae and their diatom epiphytes in primary production also increases. The relationships and interactions between these organisms have scarcely been studied in Antarctica, and even less in the volcanic ecosystem of Deception Island, which can be seen as a...

A high-quality genome assembly and annotation of the gray mangrove, Avicennia marina

Guillermo Friis, Joel Vizueta, David R. Nelson, Basel Khraiwesh, Enas Qudeimat, Kourosh Salehi-Ashtiani, Alejandra Ortega, Alyssa Marshell, Carlos M. Duarte & Edward Smith
The gray mangrove [Avicennia marina (Forsk.) Vierh.] is the most widely distributed mangrove species, ranging throughout the Indo-West Pacific. It presents remarkable levels of geographic variation both in phenotypic traits and habitat, often occupying extreme environments at the edges of its distribution. However, subspecific evolutionary relationships and adaptive mechanisms remain understudied, especially across populations of the West Indian Ocean. High-quality genomic resources accounting for such variability are also sparse. Here we report the first chromosome-level...

Correlates of substitution rate variation in a robust Procellariiform seabird phylogeny

Andrea Estandia, Terry Chesser, Helen James, Max Levy, Joan Ferrer-Obiol, Vincent Bretagnolle, Jacob González-Solís & Andreanna Welch
Molecular substitution rates vary among branches and can lead to inaccurate reconstructions of evolutionary relationships and obscure the true phylogeny of affected clades. Body mass is often assumed to have a major influence on substitution rate, though other factors such as population size, life history traits, and flight demands are also thought to have an influence. Birds of the order Procellariiformes—which encompasses petrels, storm-petrels and albatrosses—show a striking 900-fold difference in body mass between the...
