Data from: From parasitism to mutualism: unexpected interactions between a cuckoo and its host

Daniela Canestrari, Diana Bolopo, Ted C. J. Turlings, Gregory Röder, José M. Marcos & Vittorio Baglione
Avian brood parasites lay eggs in the nests of other birds, which raise the unrelated chicks and typically suffer partial or complete loss of their own brood. However, carrion crows Corvus corone corone can benefit from parasitism by the great spotted cuckoo Clamator glandarius. Parasitized nests have lower rates of predation-induced failure due to production of a repellent secretion by cuckoo chicks, but among nests that are successful, those with cuckoo chicks fledge fewer crows....

Data from: Health impact assessment of air pollution in Valladolid, Spain

Mario Cárdaba Arranz, María Fe Muñoz Moreno, Alicia Armentia Medina, Margarita Alonso Capitán, Fernando Carreras Vaquer & Ana Almaraz Gómez
Objective: to estimate the attributable and targeted avoidable deaths of outdoor air pollution by ambient PM10, PM2.5 and O3 according to specific WHO methodology. Design: health impact assessment. Setting:City of Valladolid, Spain (around 300.000 residents). Data sources: demographics; mortality; pollutant concentrations collected 1999-2008. Main outcome measures: attributable fractions (AFs); attributable and targeted avoidable deaths (ADs; TADs) per year for 1999 – 2008. Results: Higher TADs estimates (shown here) were obtained when assuming as “target” concentrations...

Data from: Contrasting species decline but high sensitivity to increasing water stress on a mixed pine-oak ecotone

Guillermo Gea-Izquierdo, Ismael Aranda, Isabel Cañellas, Isabel Dorado-Liñán, Jose Miguel Olano & Dario Martin-Benito
1. Forest decline under environmental stress is expressed by regeneration failure and accelerated mortality in all ontogenic stages at the population level. Characterizing functional traits and mechanisms that best capture species decline and mortality is essential to assess forest dynamics. 2. We analyzed sensitivity to increasing water stress in two species with different water-use strategies on a mixed Quercus pyrenaica - Pinus sylvestris forest where adult pines express vulnerability to climate change but oaks do...

Data for: Growing faster, longer or both? Modelling plastic response of Juniperus communis growth phenology to climate change

Jan Tumajer, Allan Buras, Jesús Julio Camarero, Marco Carrer, Rohan Shetti, Martin Wilmking, Jan Altman, Gabriel Sangüesa-Barreda & Jiří Lehejček
Aim: Plant growth and phenology plastically respond to changing climatic conditions both in space and time. Species-specific levels of growth plasticity determine biogeographical patterns and the adaptive capacity of species to climate change. However, a direct assessment of spatial and temporal variability in radial-growth dynamics is complicated, as long records of cambial phenology do not exist. Location: 16 sites across European distribution margins of Juniperus communis L. (the Mediterranean, the Arctic, the Alps and the...

Data from: Inferring selection in instances of long‐range colonization: the Aleppo pine (Pinus halepensis) in the Mediterranean Basin

Rose Ruiz Daniels, Richard S. Taylor, María Jesús Serra-Varela, Giovanni G. Vendramin, Santiago C. González-Martínez & Delphine Grivet
Teasing apart the effects of natural selection and demography on current allele frequencies is challenging, due to both processes leaving a similar molecular footprint. In particular, when attempting to identify selection in species that have undergone a recent range expansion, the increase of genetic drift at the edges of range expansions (“allele surfing”) can be a confounded factor. To address this potential issue, we first assess the long-range colonisation history of the Aleppo pine across...

Data from: Hypoglycemia Following intravenous insulin plus glucose for hyperkalemia in patients with impaired renal function

Armando Coca, Ana Lucia Valencia, Jesus Bustamante, Alicia Mendiluce & Jürgen Floege
Background: Hypoglycemia is a serious complication following the administration of insulin for hyperkalemia. We determined the incidence of hypoglycemia and severe hypoglycemia (blood glucose <70 or ≤40 mg/dl, respectively) in a cohort of AKI and non-dialysis dependent CKD patients who received an intravenous infusion of insulin plus glucose to treat hyperkalemia. Methods: We retrospectively reviewed charts of all AKI and non-dialysis dependent CKD patients who received 10 U of insulin plus 50 g glucose to...

Data from: Spatial genetic structure in continuous and fragmented populations of Pinus pinaster Aiton

Ana De-Lucas, Santiago González-Martínez, Giovanni G Vendramin, Elena Hidalgo & Myriam Heuertz
Habitat fragmentation, i.e., the reduction of populations into small isolated remnants, is expected to increase spatial genetic structure (SGS) in plant populations through non-random mating, lower population densities and potential aggregation of reproductive individuals. We investigated the effects of population size reduction and genetic isolation on SGS in maritime pine (Pinus pinaster Aiton) using a combined experimental and simulation approach. Maritime pine is a wind-pollinated conifer which has a scattered distribution in the Iberian Peninsula...

Data from: A three-dimensional computer simulation of feeding behaviour in red and giant pandas relates skull biomechanics with dietary niche partitioning

Borja Figueirido, Zhijie Jack Tseng, Francisco J. Serrano-Alarcón, Alberto Martín-Serra & Juan F. Pastor
The red (Ailurus fulgens) and giant (Ailuropoda melanoleuca) pandas are mammalian carnivores convergently adapted to a bamboo feeding diet. However, whereas Ailurus forage almost entirely on younger leaves, fruits and tender trunks, Ailuropoda rely more on trunks and stems. Such a difference in foraging mode is considered as strategy for resource partitioning where they are sympatric. Here we use FEA to test for mechanical differences and similarities in skull performance between Ailurus and Ailuropoda related...

Data from: Assessing vulnerability of functional diversity to species loss: a case study in Mediterranean agricultural systems

Carlos P. Carmona, Irene Guerrero, Manuel B. Morales, Juan J. Oñate & Begoña Peco
Increasing land-use intensification is leading to biodiversity losses world-wide, which can reduce the functioning of ecosystems. However, it is increasingly clear that not all species are equally important for ecosystem processes: whereas the loss of a functionally unique species may reduce the capacity of the community to perform some functions, losing a functionally redundant species should have a much smaller impact. Assessing the vulnerability of functional diversity (FD) to species extinctions can help to predict...

Data from: Capturing neutral and adaptive genetic diversity for conservation in a highly structured tree species

Isabel Rodríguez-Quilón, Luis Santos-Del-Blanco, María Jesús Serra-Varela, Jarkko Koskela, Santiago César González-Martínez & Ricardo Alía
Preserving intraspecific genetic diversity is essential for long-term forest sustainability in a climate change scenario. Despite that, genetic information is largely neglected in conservation planning, and how conservation units should be defined is still heatedly debated. Here, we use maritime pine (Pinus pinaster Ait.), an outcrossing long lived tree with a highly fragmented distribution in the Mediterranean biodiversity hotspot, to prove the importance of accounting for genetic variation - at both neutral molecular markers and...

Data from: Species interactions increase the temporal stability of community productivity in Pinus sylvestris-Fagus sylvatica mixtures across Europe

Miren Del Río, Hans Pretzsch, Ricardo Ruiz-Peinado, Evy Ampoorter, Peter Annighöfer, Ignacio Barbeito, Kamil Bielak, Gediminas Brazaitis, Lluis Coll, Lars össler, Marek Fabrika, David I. Forrester, Michael Heym, Václav Hurt, Viktor Kurylyak, Magnus Löf, Fabio Lombardi, Ekaterina Makrickiene, Bratislav Matovic, Frits Mohren, Renzo Motta, Jan Den Ouden, Maciej Pach, Quentin Ponette, Gerhard Schütze … & Lars Drössler
1.There is increasing evidence that species diversity enhances the temporal stability of community productivity in different ecosystems, although its effect at population and tree levels seems to be negative or neutral. Asynchrony in species responses to environmental conditions was found to be one of the main drivers of this stabilizing process. However, the effect of species mixing on the stability of productivity, and the relative importance of the associated mechanisms, remain poorly understood in forest...

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: Fine-scale spatial associations between functional traits and tree growth

Alex Fajardo & Eduardo Velázquez
This data set relates to a 40x60 m2 stem-mapped plot that was established in a temperate rainforest of southern Chile. It contains data for each individual stem located within the plot. Each individual is characterized by a species code, diameter at breast height (dbh, 1.35 m), diameter at coring height (dch, ca. 30 cm), x and y coordinates, basal area index of the last 10 years (bai, cm2), and growth efficiency (ge, cm2/cm2).

Data from: Environmental conditions and vascular cambium regulate carbon allocation to xylem growth in deciduous oaks

Gonzalo Pérez-De-Lis, José Miguel Olano, Vicente Rozas, Sergio Rossi, Rosa Ana Vázquez-Ruiz & Ignacio García-González
Environmental conditions and the structure of the dormant cambium are assumed to affect seasonal patterns of cambial activity, hence controlling allocation of non-structural carbohydrates (NSC) to growth. However, seasonal dynamics of xylogenesis, and their connections with NSC content and dormant cambium size, have been rarely assessed along an environmental gradient. We monitored xylogenesis and leaf phenology during 2012 and 2013, and NSC in 2012, for the drought-sensitive Quercus robur and the drought-tolerant Quercus pyrenaica along...

Data from: The Atlantic-Mediterranean watershed, river basins and glacial history shape the genetic structure of Iberian poplars

David Macaya-Sanz, Myriam Heuertz, Nuria Alba, Unai López De Heredia, Ana De-Lucas, Elena Hidalgo, Carmen Maestro, Arantxa Prada, Ricardo Alía & Santiago C. González-Martínez
Recent phylogeographic studies in several organisms have elucidated the varied effects of Pleistocene glaciations and of Pre-Pleistocene events on populations from glacial refuge areas. This study investigates those effects in riparian trees (Populus spp.), whose particular features may convey enhanced resistance to climate fluctuations. We analysed the phylogeographic structure of white, black and grey poplars (44, 13 and two populations, respectively) in the Iberian Peninsula using plasmid DNA microsatellites and sequences, we assessed fine-scale spatial...

Data from: Spatiotemporal variation of host use in a brood parasite: the role of the environment

Vittorio Baglione, Diana Bolopo, Daniela Canestrari, Juan Gabriel Martínez, María Roldán, Marta Vila & Manuel Soler
Avian brood parasites should target the most profitable host species, but current conditions might locally influence their choice, producing geographic mosaics of coevolution. Throughout Europe, the magpie Pica pica has been invariably reported as the primary host of the great spotted cuckoo Clamator glandarius, whereas the carrion crow Corvus corone is the secondary one. However, we found that this pattern reversed in northern Spain, where up to 70% of carrion crow nests were parasitized versus...
