Data from: Inferring roles in defense from metabolic allocation of rice diterpenoids

Xuan Lu, Juan Zhang, Benjamin Brown, Riqing Li, Julio Rodríguez-Romero, Aileen Berasategui, Bo Liu, Meimei Xu, Dangping Luo, Zhiqiang Pan, Scott R. Baerson, Jonathan Gershenzon, Zhaohu Li, Ane Sesma, Bing Yang & Reuben J. Peters
Among their responses to microbial infection, plants deploy an arsenal of antibiotic natural products. While these historically have been identified on the basis of their antibiotic activity in vitro, this leaves open the question of their relevance to defense in planta. The vast majority of such natural products from the important crop plant rice (Oryza sativa) are diterpenoids whose biosynthesis proceeds via either ent- or syncopalyl diphosphate (CPP) intermediates, and which were isolated on the...

Data from: Ancient DNA reveals differences in behaviour and sociality between brown bears and extinct cave bears

Gloria Gonzalez-Fortes, Aurora Grandal-D'Anglade, Ben Kolbe, Daniel Fernandes, Ioana N. Meleg, Ana Garcia-Vazquez, Ana C. Pinto-Llona, Silviu Constantin, Trino J. De Torres, Jose E. Ortiz, Christine Frischauf, Gernot Rabeder, Michael Hofreiter, Axel Barlow & Gloria G. Fortes
Ancient DNA studies have revolutionized the study of extinct species and populations, providing insights on phylogeny, phylogeography, admixture and demographic history. However, inferences on behaviour and sociality have been far less frequent. Here, we investigate the complete mitochondrial genomes of extinct Late Pleistocene cave bears and middle Holocene brown bears that each inhabited multiple geographically proximate caves in northern Spain. In cave bears, we find that, although most caves were occupied simultaneously, each cave almost...

Linguistic laws in speech: the case of Catalan and Spanish

Ivan González Torre, Antoni Hernández-Fernández, Juan-María Garrido & Lucas Lacasa
In this work we explore in an oral corpus of Catalan and Spanish (Glissando Corpus) four classical linguistic laws (Zipf's law, Herdan's law, Brevity law, and Menzerath-Altmann's law) in oral communication, both in physical units and in symbolic units measured in speech transcriptions, and we also reviewed two more laws recently reformulated: lognormality law and size-rank law. Our results reinforce with empirical evidence in two more languages the 'physical hypothesis' according to which linguistic laws...

Plant community data for European ecoregions

Jose A. Capitan, Sara Cuenda, Alejandro Ordoñez & David Alonso
Patterns in macroecology are related to species occurrence across meaningful spatial and temporal scales. The dataset provided here reports species distribution data (presence-absence) for herbaceous plants across a number of European habitats (ecoregions). Species occurrence is accompanied by the corresponding plant's maximun stem height values. This dataset has been used to unveil patterns of herbaceous plant height clustering in mid-latitude European ecoregions. Presence-absence data for herbaceous plants were drawn from Atlas Florae Europaeae (Jalas &...

Data from: Mechanical and structural adaptations to migration in the flight feathers of a Palaearctic passerine

Iván De La Hera, Irene Hernández-Téllez, José Pérez-Rigueiro, Javier Pérez-Tris, Francisco Rojo & José Luis Tellería
Current avian migration patterns in temperate regions have been developed during the glacial retreat and subsequent colonization of the ice-free areas during the Holocene. This process resulted in a geographic gradient of greater seasonality as latitude increased that favoured migration-related morphological and physiological (co)adaptations. Most evidence of avian morphological adaptations to migration comes from the analysis of variation in the length and shape of the wings, but the existence of intra-feather structural adjustments has been...

Stormwater harvesting in ephemeral streams: how to effectively bypass clogging layers and thick vadose zones

Jose David Henao Casas , Fritz Kalwa , Marc Walther & Randolf Rausch
In drylands, stormwater is often collected in surface basins and subsequently stored in shallow aquifers via infiltration to cope with water scarcity. These groundwater recharge schemes are often accompanied by high evaporation rates and hygiene problems due to low infiltration rates, which are a consequence of clogging layers on the topsoil and the presence of a thick vadose zone. The present study aims to develop a conceptual solution to increase groundwater recharge rates in stormwater...

Pseudo-dynamic analysis of heart tube formation in the mouse reveals strong regional variability and early left-right asymmetry

Isaac Esteban
We provide the first and complete atlas for morphometric analysis and visualization of heart tube morphogenesis, reporting morphological variability and early emergence of left-right asymmetry patterns.

Building deformation caused by tunnelling: centrifuge modelling

Stefan Ritter, Giorgia Giardina, Andrea Franza & Matthew DeJong
This paper investigates the deformation of buildings due to tunnelling-induced soil displacements. Centrifuge model tests of 3D printed building models subject to a plane-strain tunnel excavation in dense, dry sand are discussed. The small-scale structures replicate important building characteristics including brittle material properties similar to masonry, a realistic building layout, façade openings, strip footings and a rough soil-structure interface. Digital images were captured during the experiments, enabling image-based measurements of the building response. Results demonstrate...

Data from: Massive sequencing of Ulmus minor's transcriptome provides new molecular tools for a genus under the constant threat of Dutch elm disease

Pedro Perdiguero, Martin Venturas, Maria Teresa Cervera, Luis Gil & Carmen Collada
Elms, especially Ulmus minor and Ulmus americana, are carrying out a hard battle against Dutch elm disease (DED). This vascular wilt disease, caused by Ophiostoma ulmi and O. novo-ulmi, appeared in the twentieth century and killed millions of elms across North America and Europe. Elm breeding and conservation programmes have identified a reduced number of DED tolerant genotypes. In this study, three U. minor genotypes with contrasted levels of tolerance to DED were exposed to...

Data from: Removing interactions, rather than species, casts doubt on the high robustness of pollination networks

Silvia Santamaría, Javier Galeano, Juan Manuel Pastor & Marcos Méndez
In the last 15 years, a complex networks perspective has been increasingly used in the robustness assessment of ecological systems. It is therefore crucial to assess the reliability of such tools. Based on the traditional simulation of node (species) removal, mutualistic pollination networks are considered to be relatively robust because of their 1) truncated power-law degree distribution, 2) redundancy in the number of pollinators per plant and 3) nested interaction pattern. However, species removal is...

Data from: Using genomic tools to maintain diversity and fitness in conservation programmes

Maria Angeles Rodriguez De Cara, Beatriz Villanueva, Miguel Angel Toro & Jesús Fernández
Conservation programmes aim at maximising the survival probability of populations, by minimising the loss of genetic diversity, which allows populations to adapt to changes, and controlling inbreeding increases. The best known strategy to achieve these goals is optimising the contributions of the parents, to minimise global coancestry in their offspring. Results on neutral scenarios showed that management based on molecular coancestry could maintain more diversity than management based on genealogical coancestry when a large number...

Data from: How to best threshold and validate stacked species assemblages? Community optimisation might hold the answer

Daniel Scherrer, Manuela D'Amen, Rui F. Fernandes, Rubén G. Mateo & Antoine Guisan
PLEASE NOTE, THESE DATA ARE ALSO REFERRED TO IN TWO OTHER PUBLICATIONS. PLEASE SEE DOI: 10.1111/ddi.12548 AND https://doi.org/10.1111/geb.12357 --- The popularity of species distribution models (SDMs) and the associated stacked species distribution models (S‐SDMs), as tools for community ecologists, largely increased in recent years. However, while some consensus was reached about the best methods to threshold and evaluate individual SDMs, little agreement exists on how to best assemble individual SDMs into communities, that is, how...

Data comprise greenhouse gas measurements, soil horizon depth, bulk density, loss on ignition, pH, soil phosphorus, carbon and nitrogen, plant species cover, air temperature, soil temperature, soil moisture and surface leaf moisture. Greenhouse gas measurements were taken in the field. Soil cores were collected, then processed and analysed in the laboratory. Plant species...

Data from: Microsites of seed arrival: spatio-temporal variations in complex seed-disperser networks

Ana I. García-Cervigón, Magdalena Zywiec, Miguel Delibes, Alberto Suárez-Esteban, Ramon Perea & Jose M. Fedriani
Microsites where seeds arrive during the dispersal process determine plant reproductive success, affecting the quality of dispersal. Despite their crucial role for plant recruitment, very few studies have addressed spatio-temporal variations in microsites of seed arrival in complex seed-disperser networks. Using an endozoochorous dispersal system, we characterized the microsites of seed arrival of eight fleshy-fruited plant species dispersed by five mammal species during two consecutive seasons across three sites in a Mediterranean environment (n =...

Data from: Spatial correlated games

Ramon Alonso-Sanz
The games are played in a two-dimensional lattice where the players interact with their neighbours. Four game-types are scrutinized by allowing the players to adopt the strategy of their best paid mate neighbour in iterated games. Particular attention is paid in the study to the effect of variable degree of correlation on Nash equilibrium strategy pairs.

Data from: Plant water potential improves prediction of empirical stomatal models

William R. L. Anderegg, Stephen Pacala, John S. Sperry, Brendan Choat, Daniel J. Chmura, Thomas Kolb, Frederick Meinzer, Pilar Pita, Víctor Resco De Dios & Brett T. Wolfe
Climate change is expected to lead to increases in drought frequency and severity, with deleterious effects on many ecosystems. Stomatal responses to changing environmental conditions form the backbone of all ecosystem models, but are based on empirical relationships and are not well-tested during drought conditions. Here, we use a dataset of 34 woody plant species spanning global forest biomes to examine the effect of leaf water potential on stomatal conductance and test the predictive accuracy...

Data from: Population clustering and clonal structure evidence the relict state of Ulmus minor Mill. in the Balearic Islands

Luis Gil, Pablo Fuentes-Utrilla, María Valbuena-Carabaña & Richard Ennos
Field elm (Ulmus minor) is a riparian tree that grows in rare, small populations scattered along temporary watercourses in the Balearic Islands, nowadays mostly covered with Mediterranean vegetation. Agriculture and farming on the fertile land along the periodically flooded plains have reduced the elm populations to sparse tree lines along the creek beds. The presence of field elm in this very anthropic landscape has led some authors to consider it as an introduced species in...

What feeds on Quercus ilex L.? A biogeographical approach to studying trophic interactions in a Mediterranean keystone species

Juan Antonio Hernández-Agüero, Ildefonso Ruiz-Tapiador & Luis Cayuela
Holm oak (Quercus ilex L.) is regarded as a keystone plant species. Although trophic interactions may affect the phytophagous species distribution and abundance, the number of arthropod species using holm oak as a food resource and their levels of host specificity is not yet known. Here we aim to quantify these species, their feeding strategies and conservation status, investigate the taxonomic relatedness in each trophic guild and assess their degree of host specificity with the...

Using retrospective life-tables to assess the effect of extreme climatic conditions on ungulate demography

Marta Peláez Beato, Alfonso San Miguel, Carlos Rodríguez-Vigal, Ángel Moreno-Gómez, Amanda García Del Rincón & Ramón Perea
In Mediterranean areas, severe drought events are expected to intensify in forthcoming years as a consequence of climate change. These events may increase physiological and reproductive stress of wild populations producing demographic changes and distribution shifts. We used retrospective life tables to understand demographic changes on a wild population after severe drought events. We studied the impact of two extreme events (2003 and 2005) on the population dynamics of our model species, the red deer...

Data from: Species divergence and maintenance of species cohesion of three closely related Primula species in the Qinghai-Tibet Plateau

Guangpeng Ren, Rubén G. Mateo, Antoine Guisan, Elena Conti & Nicolas Salamin
Aim: Understanding the relative roles of geography and ecology in driving speciation, population divergence and maintenance of species cohesion is of great interest to molecular ecology. Closely related species that are parapatrically distributed in mountainous areas provide an ideal model to evaluate these key issues, especially when genomic data are analyzed within a spatially and ecologically explicit context. Here we used three closely related species of Primula that occur in the Himalayas, the Hengduan Mountains...

Data from: Virulence evolution of a generalist plant virus in a heterogeneous host system

Mónica Betancourt, Fernando Escriu, Aurora Fraile & Fernando García-Arenal
Modelling virulence evolution of multihost parasites in heterogeneous host systems requires knowledge of the parasite biology over its various hosts. We modelled the evolution of virulence of a generalist plant virus, Cucumber mosaic virus (CMV) over two hosts, in which CMV genotypes differ for within-host multiplication and virulence. According to knowledge on CMV biology over different hosts, the model allows for inoculum flows between hosts and for host co-infection by competing virus genotypes, competition affecting...

Tree growth response to drought partially explains regional-scale growth and mortality patterns in Iberian forests

Antonio Gazol, J. Julio Camarero, Raúl Sánchez-Salguero, Miguel A. Zavala, Xavier Serra-Maluquer, Emilia Gutiérrez, Martín De Luis, Gabriel Sangüesa-Barreda, Klemen Novak, Vicente Rozas, Pedro A. Tíscar, Juan C. Linares, Edurne Martínez Del Castillo, Montse Ribas, Ignacio García-González, Fernando Silla, Álvaro Camison, Mar Génova, José M. Olano, Ana-Maria Hereş, Jorge Curiel Yuste, Luis A. Longares, Andrea Hevia, J. Diego Galván & Paloma Ruiz-Benito
To quantify responses to drought from different data sources we take advantage of an extensive network of cross-dated tree-ring data with increment cores from 16 tree species sampled across the Spanish Iberian Peninsula (hereafter abbreviated as RWI-net), and of the Spanish National Forest Inventory (hereafter abbreviated as NFI) sampling tree and plot level data each km in forested areas. We selected the five most severe droughts that have affected each selected RWI-net population in the...

Hydropeaking affects germination and establishment of riverbank vegetation

María D. Bejarano, Álvaro Sordo-Ward, Carlos Alonso, Roland Jansson & Christer Nilsson
Hydropeaking, defined as frequent and rapid variation in flow in regulated rivers with hydropower plants over a short period of time, usually sub-daily to weekly, alters hydraulic parameters such as water levels or flow velocity and exerts strong impacts on fluvial ecosystems. We evaluated the effects of hydropeaking on riverbank vegetation, specifically assessing the germination and establishment of seedlings and cuttings of plant species representing a variation in traits. We used seeds and seedlings and...
