Abstract Background The Symptom Checklist (SCL) developed by the Health Behaviour in School-aged Children (HBSC) study is a non-clinical measure of psychosomatic complaints (e.g., headache and feeling low) that has been used in numerous studies. Several studies have investigated the psychometric characteristics of this scale; however, some psychometric properties remain unclear, among them especially a) dimensionality, b) adequacy of the Graded Response Model (GRM), and c) measurement invariance across countries. Methods Data from 229,906 adolescents...

La construcción de la profesionalidad docente, una tarea permanente

Francisco Pérez García
Siempre que se aborda el problema de la enseñanza, su organización, sus resultados, su adecuación a las necesidades sociales, el currículum…, se termina fijando la mirada en una pieza clave: el profesorado. Y, sin duda, el profesorado es ese elemento clave del sistema, a través del cual pasa todo y sin el cual es impensable concebir el propio funcionamiento de la educación. Pero, más allá de las proclamaciones -o de las lamentaciones- en relación con...

Nager, Jan-Åke Nilsson … & Ruedi G. Nager
Coexistence between great tits Parus major and blue tits Cyanistes caeruleus, but also other hole‐nesting taxa, constitutes a classic example of species co‐occurrence resulting in potential interference and exploitation competition for food and for breeding and roosting sites. However, the spatial and temporal variations in coexistence and its consequences for competition remain poorly understood. We used an extensive database on reproduction in nest boxes by great and blue tits based on 87 study plots across...

Data supporting: Drivers of individual-based, antagonistic interaction networks during plant range expansion

Jorge Isla, Miguel Jácome-Flores, Pareja Daniel & Jordano Pedro
1. Range expansion in plant populations, especially at the colonization front, can be either limited by disproportionately large effects of antagonistic interactions or facilitated by their release. How the strength of antagonistic interactions changes along successional gradients during range expansion is still poorly documented, especially when diverse assemblages of plant antagonists (rodents, invertebrates, and birds) combine within interaction networks. 2. We study the changes in individual-based, predispersal seed-pulp predator networks along a colonization gradient in...

Data from: Two New Species of Aira (Poaceae) from the Iberian Peninsula and the Balearic Islands

Maria Angeles Ortiz Herrera, Llorenç Sáez, Javier López-Alvarado, Pere Fraga, Regina Berjano & Carlos Romero-Zarco
Two new diploid species, Aira minoricensis and Aira hercynica are described and illustrated, along with chromosome counts, risk assessment, distribution and habitat, phenology, and comparisons with morphologically similar species. A comparative table and a key for the species of Aira for the Iberian Peninsula and the Balearic Islands are provided to assist in the identification of these overlooked species, and their relationships to other taxa are discussed.

Redox controls RecA protein activity via reversible oxidation of its methionine residues

Benjamin Ezraty, Camille Henry, Frederic Barras, Laurent Loiseau, Alexandra Vergnes, Didier Vertommen, Angela Mérida-Floriano, Sindhu Chitteni-Pattu, Elizabeth Anne Wood, Josep Casadesús & Michael M. Cox
Reactive oxygen species (ROS) cause damage to DNA and proteins. The RecA protein plays a central role in the bacterial response to DNA damage. Here we report that RecA itself is also targeted by ROS. In vivo consequences of RecA oxidation include defects in SOS induction, DNA repair efficiency, and P1 transduction. In vitro, oxidized RecA fails to display ATPase activity, DNA strand exchange capacity and formation of nucleofilaments. Consistently, mass spectrometry analysis of oxidized...

Cold winters have morph-specific effects on natal dispersal distance in a wild raptor

Arianna Passarotto, Arianna Passarotto, Chiara Morosinotto, Jon Brommer, Esa Aaltonen, Kari Ahola, Teuvo Karstinen & Patrik Karell
Dispersal is a key process with crucial implications in spatial distribution, density and genetic structure of species’ populations. Dispersal strategies can vary according to both individual and environmental features, but putative phenotype-by-environment interactions have rarely been accounted for. Melanin-based color polymorphism is a phenotypic trait associated with specific behavioral and physiological profiles and is therefore a good candidate trait to study dispersal tactics in different environments. Here, using a 40 years dataset of a population...

Data from: Contrasting plant water-use responses to groundwater depth in coastal dune ecosystems

Cristina Antunes, Mari Cruz Díaz Barradas, María Zunzunegui, Simone Vieira, Ângela Pereira, Andreia Anjos, Otília Correia, Maria João Pereira & Cristina Máguas
1.Groundwater lowering can produce dramatic changes in the physiological performance and survival of plant species. The impact of decreasing water availability due to climate change and anthropogenic groundwater extraction on coastal dune ecosystems has become of increasing concern, with uncertainties about how vegetation will respond in both the short and long terms. 2.We aimed to evaluate the water‐use responses of different plant functional types to increasing groundwater table depth and how this would affect their...

Data from: The building of a biodiversity hotspot across a land-bridge in the Mediterranean

Rafael Molina-Venegas, Abelardo Aparicio, Sébastien Lavergne & Juan Arroyo
Many of the macroevolutionary processes that have shaped present-day phylogenetic patterns were caused by geological events such as plate tectonics and temporary land-bridges. The study of spatial patterns of phylogenetic diversity can provide insights into these past events. Here we focus on a western Mediterranean biodiversity hotspot located in the southern Iberian Peninsula and northwest Africa, two regions that are separated by the Strait of Gibraltar. We explore the spatial structure of the phylogenetic relationships...

Data from: The spatial structure of phylogenetic and functional diversity in the United States and Canada: an example using the sedge family (Cyperaceae)

Daniel Spalink, Jocelyn Pender, Marcial Escudero, Andrew L. Hipp, Eric H. Roalson, Julian R. Starr, Marcia J. Waterway, Lynn Bohs & Kenneth J. Sytsma
Systematically quantifying diversity across landscapes is necessary to understand how clade history and ecological heterogeneity contribute to the origin, distribution, and maintenance of biodiversity. Here, we chart the spatial structure of diversity among all species in the sedge family (Cyperaceae) throughout the USA and Canada. We first identify areas of remarkable species richness, phylogenetic diversity, and functional trait diversity, and highlight regions of conservation priority. We then test predictions about the spatial structure of this...

Data from: Pliocene-Pleistocene ecological niche evolution shapes the phylogeography of a Mediterranean plant group

Carmen Benítez Benítez, Marcial Escudero, Francisco Rodriguez-Sanchez, Santiago Martín-Bravo & Pedro Jiménez Mejías
Estimating species ability to adapt to environmental changes is crucial to understand their past and future response to climate change. The Mediterranean basin has experienced remarkable climatic changes since the Miocene, which have greatly influenced the evolution of the Mediterranean flora. Here we examine the evolutionary history and biogeographic patterns of two sedge sister species (Carex, Cyperaceae) restricted to the western Mediterranean basin, but with Pliocene fossil record in central Europe. In particular, we estimated...

Data from: Range-wide population genetics and variation in morph ratio in style-dimorphic Narcissus papyraceus (Amaryllidaceae)

Violeta I. Simón-Porcar, F. Xavier Picó & Juan Arroyo
Premise of the study: Theoretical models state that natural selection and mating patterns account for floral morph ratio in style- polymorphic plants. However, the demographic history of populations can also influence variation in morph ratios. If so, we hypothesize an association between the morph ratios and the genetic structure across populations. Methods: We used nuclear microsatellites to assess genetic variation and structure in populations of Narcissus papyraceus, a style-dimorphic plant whose floral morph ratios (L-morph...

Data from: Effects of habitat fragmentation on parental correlations in the seed rain of a bird-dispersed species

Clara Parejo-Farnés, Juan José Robledo-Arnuncio, Rafael G. Albaladejo, Encarnación Rubio-Pérez & Abelardo Aparicio
Seed dispersal plays a crucial role in natural forest regeneration. Changes in the seed rain due to anthropogenic habitat alteration can influence seedling recruitment patterns and affect the evolutionary dynamics of populations. Using a combined endocarp-embryo microsatellite assay of naturally dispersed seeds, we concomitantly quantify the contribution of contemporary pollen and seed dispersal to the genetic structure of the seed rain of the shrub species Pistacia lentiscus L. The study was conducted in two consecutive...

Turgor loss point predicts survival responses to experimental and natural drought in tropical tree seedlings

Leonor Álvarez-Cansino, Liza S. Comita, F. Andrew Jones, Eric Manzané-Pinzón, Luke Browne & Bettina M.J. Engelbrecht
Identifying key traits that can serve as proxies for species drought resistance is crucial for predicting and mitigating effects of climate change in diverse plant communities. Turgor loss point (πtlp) is a recently emerged trait that has been linked to species distributions across gradients of water availability. However, a direct relationship between πtlp and species ability to survive drought has yet to be established for woody species. Using a manipulative field experiment to quantify species...

Phylogenomic resolution of sea spider diversification through integration of multiple data classes

Jesus Ballesteros, Emily Setton, Carlos Santibáñez-López, Claudia Arango, Georg Brenneis, Saskia Brix, Kevin Corbett, Esperanza Cano-Sánchez, Merai Dandouch, Geoffrey Dilly, Marc Eleaume, Guilherme Gainett, Cyril Gallut, Sean McAtee, Lauren McIntyre, Randy Moran, Pablo López-González, Gerhard Scholtz, Clay Williamson, Arthur Woods, Jakob Zehms, Ward Wheeler & Prashant Sharma
Despite significant advances in invertebrate phylogenomics over the past decade, the higher-level phylogeny of Pycnogonida (sea spiders) remains elusive. Due to the inaccessibility of some small-bodied lineages, few phylogenetic studies have sampled all sea spider families. Previous efforts based on a handful of genes have yielded unstable tree topologies. Here, we inferred the relationships of 89 sea spider species using targeted capture of the mitochondrial genome, 56 conserved exons, 101 ultraconserved elements, and three nuclear...

Warm range margin of boreal bryophytes and lichens not directly limited by temperatures

Caroline Greiser, Johan Ehrlén, Miska Luoto, Eric Meineri, Sonia Merinero, Benny Willman & Kristoffer Hylander
1. Species at their warm range margin are potentially threatened by higher temperatures, but may persist in microrefugia. Whether such microsites occur due to more suitable microclimate or due to lower biotic pressure from e.g. competitive species, is still not fully resolved. 2. We examined whether boreal bryophytes and lichens show signs of direct climate limitation, i.e. whether they perform better in cold and/or humid microclimates at their warm range margin. We transplanted a moss,...

The evolutionary history of sedges (Cyperaceae) in Madagascar

Isabel Larridon, Daniel Spalink, Pedro Jiménez-Mejías, José Ignacio Márquez-Corro, Santiago Martín-Bravo & Marcial Escudero
Aim: Madagascar is renowned for its unparalleled biodiversity and endemism. With many ecosystems under threat, research is urgently needed on its unique plant diversity. This applies both to Madagascar’s forests and treeless vegetation types. Sedges (Cyperaceae) are among the top ten species-richest angiosperm families in Madagascar (310 native species, 38% endemic), of which two thirds occur in open habitats. We aimed to infer the evolutionary history of sedges in Madagascar, by estimating the number, age...

Data from: Effects of tree architecture on pollen dispersal and mating patterns in Abies pinsapo Boiss. (Pinaceae)

Jose M. Sánchez-Robles, Juan L. García Castaño, Francisco Balao, Anass Terrab, Laura Navarro Sampedro, Karin Tremetsberger & Salvador Talavera
Plant architecture is crucial to pollination and mating in wind pollinated species. We investigate the effect of crown architecture on pollen dispersal, mating system and offspring quality, combining phenotypic and genotypic analyses in a low-density population of the endangered species Abies pinsapo. A total of 598 embryos from three relative crown height levels (bottom, middle, top) in five mother plants were genotyped using eleven nuclear microsatellite markers (nSSRs). Paternity analysis and mating system models were...
