Dissolved rhenium and other dissolved ions in Alpine catchments of the Erlenbach and Vogelbach (Switzerland) and the East River (Colorado, USA)

Robert G Hilton & Mathieu Dellinger
The measurements and data contained here were obtained to study the chemical weathering of sedimentary rocks, and more specifically the oxidation of rock organic carbon and the associated release of CO2. The primary aim was to better understand the production and mobility of the trace element rhenium during weathering, because this element has been proposed as a proxy for rock organic carbon oxidation. The study focused on three Alpine catchments that drain sedimentary rocks, which...

Data from: Rapid and dynamic alternative splicing impacts the Arabidopsis cold response transcriptome

Cristiane P. G. Calixto, Wenbin Guo, Allan B. James, Nikoleta A. Tzioutziou, Juan C. Entizne, Paige E. Panter, Heather Knight, Hugh Nimmo, Runxuan Zhang & John W. S. Brown
Plants have adapted to tolerate and survive constantly changing environmental conditions by re-programming gene expression. The dynamics of the contribution of alternative splicing (AS) to stress responses are unknown. RNA-sequencing of a time-series of Arabidopsis thaliana plants exposed to cold determines the timing of significant AS changes. This shows a massive and rapid AS response with coincident waves of transcriptional and AS activity occurring in the first few hours of temperature reduction, and further AS...

Data from: Non-linear effects of phylogenetic distance on early-stage establishment of experimentally introduced plants in grassland communities

Eva Maria Malecore, Wayne Dawson, Anne Kempel, Gregor Müller & Mark Van Kleunen
1. The phylogenetic distance of an introduced plant species to a resident native community may play a role in determining its establishment success. While Darwin’s naturalization hypothesis predicts a positive relationship, the preadaptation hypothesis predicts a negative relationship. Rigorous tests of this now so-called Darwin’s naturalization conundrum require not only information on establishment successes but also of failures, which is frequently not available. Such essential information, however, can be provided by experimental introductions. 2. Here,...

Data from: Visual and non-visual navigation in blind patients with a retinal prosthesis

Sara Garcia, Karin Petrini, Gary S. Rubin, Lyndon Da Cruz & Marko Nardini
Human adults with normal vision can combine visual landmark and non-visual self-motion cues to improve their navigational precision. Here we asked whether blind individuals treated with a retinal prosthesis could also benefit from using the resultant new visual signal together with non-visual information when navigating. Four patients (blind for 15-52 years) implanted with the Argus II retinal prosthesis (Second Sight Medical Products Inc. Sylmar, CA), and five age-matched and six younger controls, participated. Participants completed...

Data from: The contemporary distribution of Trypanosoma cruzi infection in humans, alternative hosts and vectors

Annie J. Browne, Carlos A. Guerra, Renato Vieira Alves, Veruska Maia Da Costa, Anne L. Wilson, David M. Pigott, Simon I. Hay, Steve W. Lindsay, Nick Golding & Catherine L. Moyes
Chagas is a potentially fatal chronic disease affecting large numbers of people across the Americas and exported throughout the world through human population movement. It is caused by the Trypanosoma cruzi parasite, which is transmitted by triatomine vectors to humans and a wide range of alternative host species. The database described here was compiled to allow the risk of vectorial transmission to humans to be mapped using geospatial models. The database collates all available records,...

Data from: Alien and native plant establishment in grassland communities is more strongly affected by disturbance than above- and below-ground enemies

Gregor Müller, Lena Horstmeyer, Tilman Rönneburg, Mark Van Kleunen & Wayne Dawson
Understanding the factors that drive commonness and rarity of plant species and whether these factors differ for alien and native species are key questions in ecology. If a species is to become common in a community, incoming propagules must first be able to establish. The latter could be determined by competition with resident plants, the impacts of herbivores and soil biota, or a combination of these factors. We aimed to tease apart the roles that...

Data from: Freezer on, lights off! Environmental effects on activity rhythms of fish in the Arctic

Kate L. Hawley, Carolyn M. Rosten, Thrond O. Haugen, Guttorm Christensen & Martyn C. Lucas
Polar regions are characterized by acute seasonal changes in the environment, with organisms inhabiting these regions lacking diel photoperiodic information for parts of the year. We present, to our knowledge, the first high-resolution analysis of diel and seasonal activity of free-living fishes in polar waters (74°N), subject to extreme variation in photoperiod, temperature and food availability. Using biotelemetry, we tracked two sympatric ecomorphs of lake-dwelling Arctic charr (Salvelinus alpinus n = 23) over an annual...

Data from: Flexibility, variability and constraint in energy management strategies across vertebrate taxa revealed by long-term heart rate measurements

Lewis G. Halsey, Jonathan A. Green, Sean D. Twiss, Walter Arnold, Sarah J. Burthe, Patrick J. Butler, Steve J. Cooke, David Gremillet, Thomas Ruf, Olivia Hicks, Katarzyna J. Minta, Tanya S. Prystay, Claudia A.F. Wascher, Vincent Careau, Steven J Cooke, Tania S Prystay & Claudia AF Wascher
1) Animals are expected to be judicious in the use of the energy they gain due to the costs and limits associated with its intake. The management of energy expenditure (EE) exhibited by animals has previously been considered in terms of three patterns: the constrained, independent and performance patterns of energy management. These patterns can be interpreted by regressing daily EE against maintenance EE measured over extended periods. From the multiple studies on this topic,...

Data from: Geographical variation in species' population responses to changes in temperature and precipitation

James W. Pearce-Higgins, Nancy Ockendon, David J. Baker, Jamie Carr, Elizabeth C. White, Rosamunde E. A. Almond, Tatsuya Amano, Esther Bertram, Richard B. Bradbury, Cassie Bradley, Stuart H. M. Butchart, Nathalie Doswald, Wendy Foden, David J. C. Gill, Rhys E. Green, William J. Sutherland & Edmund V. J. Tanner
Despite increasing concerns about the vulnerability of species’ populations to climate change, there has been little overall synthesis of how individual population responses to variation in climate differ between taxa, with trophic level or geographically. To address this, we extracted data from 132 long-term (≥20 years) studies of population responses to temperature and precipitation covering 236 animal and plant species across terrestrial and freshwater habitats. Temperature tended to have a greater overall impact on populations...

Data from: Phenotypic and genetic divergence among harbour porpoise populations associated with habitat regions in the North Sea and adjacent seas.

Carlos De Luna Lopez, Simon J. Goodman, Oliver Thatcher, Paul D. Jepson, Liselotte Andersen, Krystal Tolley & Alan R. Hoelzel
Determining the mechanisms that generate population structure is essential to the understanding of speciation and the evolution of biodiversity. Here, we investigate a geographic range that transects two habitat gradients, the North Sea to North Atlantic transition, and the temperate to sub-polar regions. We studied the harbour porpoise (Phocoena phocoena), a small odontocete inhabiting both sub-polar and temperate waters. To assess differentiation among putative populations we measured morphological variation at cranial traits (N=462 individuals) and...

Data from: Continent‐scale phenotype mapping using citizen scientists’ photographs

Jonathan P. Drury, Morgan Barnes, Ann E. Finneran, Maddie Harris & Gregory F. Grether
Field investigations of phenotypic variation in free‐living organisms are often limited in scope owing to time and funding constraints. By collaborating with online communities of amateur naturalists, investigators can greatly increase the amount and diversity of phenotypic data in their analyses while simultaneously engaging with a public audience. Here, we present a method for quantifying phenotypes of individual organisms in citizen scientists’ photographs. We then show that our protocol for measuring wing phenotypes from photographs...

Permian–Triassic phylogenetic and morphologic evolution of rhynchonellide brachiopods

Zhen Guo, Zhong-Qiang Chen, A. T. Harper David & Yuangeng Huang
The Rhynchonellida is a major group of brachiopods that survived the “big five” mass extinctions and flourished after the Permian-Triassic (P-Tr) crisis. However, phylogenetic and character evolution in the Rhynchonellida across the P-Tr transition is poorly understood. In view of the widespread homoplasy across this order, we employ a tip-dated Bayesian analysis to reconstruct phylogenetic relationships for Late Permian–Triassic rhynchonellides. The same data were also analyzed using three other methods: undated Bayesian, equal-weighting, and implied-weighting...

Global maps of current (1979-2013) and future (2061-2080) habitat suitability probability for 1,485 European endemic plant species

Robin Pouteau, Idoia Biurrun, Caroline Brunel, Milan Chytrý, Wayne Dawson, Franz Essl, Trevor Fristoe, Rense Haveman, Carsten Hobohm, Florian Jansen, Holger Kreft, Jonathan Lenoir, Bernd Lenzner, Carsten Meyer, Jesper Erenskjold Moeslund, Jan Pergl, Petr Pyšek, Jens-Christian Svenning, Wilfried Thuiller, Patrick Weigelt, Thomas Wohlgemuth, Qiang Yang & Mark Van Kleunen
Aims: The rapid increase in the number of species that have naturalized beyond their native range is among the most apparent features of the Anthropocene. How alien species will respond to other processes of future global changes is an emerging concern and remains largely misunderstood. We therefore ask whether naturalized species will respond to climate and land-use change differently than those species not yet naturalized anywhere in the world. Location: Global Methods: We investigated future...

Energetic limits: Defining the bounds and trade-offs of successful energy management in a capital breeder

Courtney Shuert, Lewis Halsey, Patrick Pomeroy & Sean Twiss
1. Judicious management of energy can be invaluable for animal survival and reproductive success. Capital breeding mammals typically transfer energy to their young at extremely high rates while undergoing prolonged fasting, making lactation a tremendously energy demanding period. Effective management of the competing demands of the mother’s energy needs and those of her offspring is presumably fundamental to maximising lifetime reproductive success. 2. How does the mother maximise her chances of successfully rearing her pup,...

Data from: Global vegetation patterns of the past 140,000 years

Judy Allen, Matthew Forrest, Thomas Hickler, Joy Singarayer, Paul Valdes & Brian Huntley
Aim Insight into global biome responses to climatic and other environmental changes is essential to address key questions about past and future impacts of such changes. By simulating global biome patterns 140 ka to present we aimed to address important questions about biome changes during this interval. Location Global. Taxon Plantae. Methods Using the LPJ-GUESS dynamic global vegetation model, we made 89 simulations driven using ice-core atmospheric CO2 concentrations, Earth’s obliquity, and outputs from a...

RNA-seq of Arabidopsis root growth responses to mechanical impedance

Keith Lindsey, Amy Jacobsen, Jian Xu, Jennifer Topping & George Jervis
1. The growth and development of root systems, essential for plant performance, is influenced by mechanical properties of the substrate in which the plants grow. Mechanical impedance, such as by compacted soil, can reduce root elongation and limit crop productivity. 2. To understand better the mechanisms involved in plant root responses to mechanical impedance stress, we investigated changes in the root transcriptome and hormone signalling responses of Arabidopsis to artificial root barrier systems in vitro....

Data from: Chimpanzee communities differ in their inter- and intrasexual social relationships

Bruce Rawlings, Edwin J. C. Van Leeuwen & Marina Davila-Ross
Male and female human social bonding strategies are both culturally and genetically shaped. Chimpanzees, our phylogenetically joint closest living relatives, exhibit complex social structures and show impressive cultural diversity. Whether chimpanzee male and female bonding patterns are culturally shaped remains unclear. Studies of wild chimpanzees bonding across sex show that in some communities males show strong bonds with other males, whereas in others females form particularly strong intra-sex bonds. This suggests that there may be...

How 2 and 4 year old children coordinate joint actions with peers

Federico Rossano, Jack Terwilliger, Adrian Bangerter, Emilie Genty, Raphaela Heesen & Klaus Zuberbühler
The interaction engine hypothesis postulates a uniquely human ability and motivation for social interaction. A crucial juncture in the ontogeny of the interaction engine could be around 2-4 years of age, but observational studies of children in natural contexts are lacking. Moreover, data on the ontogenetic development of joint action coordination can provide critical human data for comparative research investigating the phylogenetic roots of the interaction engine. In this study we report on focal observations...

Data from: Genomic diversity and differentiation of a managed island wild boar population

Laura Iacolina, Massimo Scandura, Daniel J. Goedbloed, Panoraia Alexandri, Richard P. M. A. Crooijmans, Greger Larson, Alan Archibald, Marco Apollonio, Lawrence B. Schook, Martien A. Groenen & Hendrik-Jan Megens
The evolution of island populations in natural systems is driven by local adaptation and genetic drift. However, evolutionary pathways may be altered by humans in several ways. The wild boar (WB) (Sus scrofa) is an iconic game species occurring in several islands, where it has been strongly managed since prehistoric times. We examined genomic diversity at 49 803 single-nucleotide polymorphisms in 99 Sardinian WBs and compared them with 196 wild specimens from mainland Europe and...

Data from: The changing environment of conservation conflict: geese and farming in Scotland

Tom H. E. Mason, Aidan Keane, Stephen M. Redpath & Nils Bunnefeld
1.Conflict between conservation objectives and human livelihoods is ubiquitous and can be highly damaging, but the processes generating it are poorly understood. Ecological elements are central to conservation conflict, and changes in their dynamics – for instance due to anthropogenic environmental change – are likely to influence the emergence of serious human-wildlife impacts and, consequently, social conflict. 2.We used mixed-effects models to examine the drivers of historic spatio-temporal dynamics in numbers of Greenland barnacle geese...

Data from: Spatio-temporal variation in fitness responses to contrasting environments in Arabidopsis thaliana

Moises Exposito-Alonso, Adrian C. Brennan, Carlos Alonso-Blanco & F. Xavier Pico
The evolutionary response of organisms to global climate change is expected to be strongly conditioned by pre-existing standing genetic variation. In addition, natural selection imposed by global climate change on fitness-related traits can be heterogeneous over time. We estimated selection of life-history traits of an entire genetic lineage of the plant A. thaliana occurring in north-western Iberian Peninsula that were transplanted over multiple years into two environmentally contrasting field sites in southern Spain, as southern...

Data from: Population differentiation in the context of Holocene climate change for a migratory marine species, the southern elephant seal

Laura J. Corrigan, Anna Fabiani, Lucas F. Chauke, Clive R. McMahon, Mark De Bruyn, Marthan N. Bester, Amanda Bastos, Claudio Campagna, Monica M.C. Muelbert & A. Rus Hoelzel
Understanding observed patterns of connectivity requires an understanding of the evolutionary processes that determine genetic structure among populations, with the most common models being associated with isolation by distance, allopatry or vicariance. Pinnipeds are annual breeders with the capacity for extensive range overlap during seasonal migrations, establishing the potential for the evolution of isolation by distance. Here we assess the pattern of differentiation among six breeding colonies of the southern elephant seal, Mirounga leonina, based...
