Carnivorous plants exploit animals as a nutritional source and have inspired long-standing questions about the origin and evolution of carnivory-related traits. To investigate the molecular bases of carnivory, we sequenced the genome of the heterophyllous pitcher plant Cephalotus follicularis, in which we succeeded in regulating the developmental switch between carnivorous and non-carnivorous leaves. Transcriptome comparison of the two leaf types and gene repertoire analysis identified genetic changes associated with prey attraction, capture, digestion and nutrient...
Data from: Towards a common methodology for developing logistic tree mortality models based on ring-width dataMaxime Cailleret, Christof Bigler, Harald Bugmann, J. Julio Camarero, Katarina Cufar, Hendrik Davi, Ilona Mészáros, Francesco Minunno, Mikko Peltoniemi, Elisabeth Robert, María-Laura Suarez, Roberto Tognetti & Jordi Martinez-Vilalta
Tree mortality is a key process shaping forest dynamics. Thus, there is a growing need for indicators of the likelihood of tree death. During the last decades, an increasing number of tree-ring based studies have aimed to derive growth–mortality functions, mostly using logistic models. The results of these studies, however, are difficult to compare and synthesize due to the diversity of approaches used for the sampling strategy (number and characteristics of alive and death observations),...
Data from: Relationships among taxonomic, functional, and phylogenetic ant diversity across the biogeographic regions of EuropeXavier Arnan, Xim Cerdá & Javier Retana
Understanding how different biodiversity components are related across different environmental conditions is a major goal in macroecology and conservation biogeography. We investigated correlations among alpha and beta taxonomic (TD), phylogenetic (PD), and functional diversity (FD) in ant communities in the five biogeographic regions most representative of western Europe; we also examined the degree of niche conservatism. We combined data from 349 ant communities composed of 154 total species, which were characterized by 10 functional traits...
Data from: Introduced Drosophila subobscura populations perform better than native populations during an oviposition choice task due to increased fecundity but similar learning abilityJulien Foucaud, Céline Moreno, Marta Pascual, Enrico L. Rezende, Luis E. Castañeda, Patricia Gibert & Frederic Mery
The success of invasive species is tightly linked to their fitness in a putatively novel environment. While quantitative components of fitness have been studied extensively in the context of invasive species, fewer studies have looked at qualitative components of fitness, such as behavioral plasticity, and their interaction with quantitative components, despite intuitive benefits over the course of an invasion. In particular, learning is a form of behavioral plasticity that makes it possible to finely tune...
Data from: Imprints of multiple glacial refugia in the Pyrenees revealed by phylogeography and palaeodistribution modelling of an endemic spiderLeticia Bidegaray-Batista, Alejandro Sánchez-Garcia, Giulia Santulli, Luigi Maiorano, Antoine Guisan, Alfried Vogler & Miquel Arnedo
Mediterranean mountain ranges harbour highly endemic biota in islandlike habitats. Their topographic diversity offered the opportunity for mountain species to persist in refugial areas during episodes of major climatic change. We investigate the role of Quaternary climatic oscillations in shaping the demographic history and distribution ranges in the spider Harpactocrates ravastellus, endemic to the Pyrenees. Gene trees and multispecies coalescent analyses on mitochondrial and nuclear DNA sequences unveiled two distinct lineages with a hybrid zone...
Data from: Morphometric variation of extant platyrrhine molars: taxonomic implications for fossil platyrrhinesMónica Nova Delgado, Jordi Galbany & Alejandro Pérez-Pérez
The phylogenetic position of many fossil platyrrhines with respect to extant ones is not yet clear. Two main hypotheses have been proposed: the layered or successive radiations hypothesis suggests that Patagonian fossils are Middle Miocene stem platyrrhines lacking modern descendants, whereas the long lineage hypothesis argues for an evolutionary continuity of all fossil platyrrhines with the extant ones. Our geometric morphometric analysis of a 15 landmark-based configuration of platyrrhines’ first and second lower molars suggest...
Data from: Active and reactive behaviour in human mobility: the influence of attraction points on pedestriansMario Gutiérrez-Roig, Oleguer Sagarra, Aitana Oltra, John R. B. Palmer, Frederic Bartumeus, Albert Diaz-Guilera & Josep Perelló
Human mobility is becoming an accessible field of study thanks to the progress and availability of tracking technologies as a common feature of smart phones. We describe an example of a scalable experiment exploiting these circumstances at a public, outdoor fair in Barcelona (Spain). Participants were tracked while wandering through an open space with activity stands attracting their attention. We develop a general modeling framework based on Langevin Dynamics, which allows us to test the...
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...
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: Spatio-temporal monitoring of deep-sea communities using metabarcoding of sediment DNA and RNAMagdalena 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,...

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: The role of morbidly obesity in the promotion of metabolic disruptions and non-alcoholic steatohepatitis by Helicobacter PyloriAlbert Lecube, Silvia Valladares, Carolina Lopez-Cano, Liliana Gutiérrez, Andreea Ciudin, José Manuel Fort, Josep Maria Reñé, Xavier Matias-Guiu, Ines De Torres, Marta Bueno, Judit Pallarés & Juan Antonio Baena
Helicobacter pylori (HP) infection has been associated to an increased rate of type 2 diabetes (T2D) and liver disease through its effect on insulin resistance and systemic inflammation. However, results are inconstant and no studies exist in morbidly obese patients, in which both insulin resistance and inflammation coexist. Material and Methods: Cross-sectional study to evaluate the relationship between HP infection and alterations in carbohydrate metabolism, lipid profile, inflammation markers, and liver disease in patients awaiting...
Data from: Global assessment of the impact of type 2 diabetes on sleep through specific questionnaires. A case-control studyAlbert 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,...

Upwelling regions are highly productive habitats targeted by wide-ranging marine predators and industrial fisheries. In this study, we track the migratory movements of eight seabird species from across the Atlantic; quantify overlap with the Canary Current Large Marine Ecosystem (CCLME) and determine the habitat characteristics that drive this association. Our results indicate the CCLME is a biodiversity hotspot for migratory seabirds; all tracked species and more than 70% of individuals used this upwelling region. Relative...
