Data from: Repeated land mass reformation limits diversification in the widespread littoral zone mosquito Anopheles sundaicus sensu lato in the Indo-Oriental Region

Magdalena Zarowiecki, Yvonne-Marie Linton, Rory J. Post, Michael J. Bangs, Pe Than Htun, Thaung Hlaing, Chang Moh Seng, Visut Baimai, Trung Ho Ding, Tho Sochantha & Catherine Walton
Southeast Asia harbours abundant biodiversity, hypothesized to have been generated by Pliocene and Pleistocene climatic and environmental change. Vicariance between the island of Borneo, the remaining Indonesian archipelago and mainland Southeast Asia caused by elevated sea levels during interglacial periods has been proposed to lead to diversification in the littoral zone mosquito Anopheles (Cellia) sundaicus (Rodenwaldt) sensu lato. To test this biogeographical hypothesis, we inferred the population history and assessed gene flow of A. sundaicus...

Data from: Relationships between plant traits, soil properties and carbon fluxes differ between monocultures and mixed communities in temperate grassland

Jonathan R. De Long, Benjamin G. Jackson, Anna Wilkinson, William J. Pritchard, Simon Oakley, Kelly E. Mason, Jörg G. Stephan, Nicholas J. Ostle, David Johnson, Elizabeth M. Baggs & Richard D. Bardgett
1. The use of plant traits to predict ecosystem functions has been gaining growing attention. Aboveground plant traits, such as leaf nitrogen (N) content and specific leaf area (SLA), have been shown to strongly relate to ecosystem productivity, respiration, and nutrient cycling. Further, increasing plant functional trait diversity has been suggested as a possible mechanism to increase ecosystem carbon (C) storage. However, it is uncertain whether belowground plant traits can be predicted by aboveground traits,...

Data from: Finite element modelling vs. classic beam theory: comparing methods for stress estimation in a morphologically diverse sample of vertebrate long bones

Charlotte A. Brassey, Lee Margetts, Andrew C. Kitchener, Philip J. Withers, Phillip L. Manning & William I. Sellers
Classic beam theory is frequently employed in biomechanics to model the stress behaviour of vertebrate long bones, particularly when creating intraspecific scaling models. Although methodologically straightforward, classic beam theory requires complex irregular bones to be approximated as slender beams, and the errors associated with simplifying complex organic structures to such an extent are unknown. Alternative approaches, such as Finite Element Analysis (FEA), whilst much more time-consuming to perform, require no such assumptions. This paper compares...

Ecosystem function and vegetation data from a land use gradient on Salisbury Plain in June 2014

Data from: Soil biota and chemical interactions promote co-existence in co-evolved grassland communities

Marina Semchenko, Siim Nettan, Anette Sepp, Qiaoying Zhang, Maria Abakumova, John Davison, Rein Kalamees, Anu Lepik, Kersti Püssa, Sirgi Saar, Merilin Saarma, Marge Thetloff & Kristjan Zobel
1. Plant populations can exhibit local adaptation to their abiotic environment, such as climate and soil properties, as well as biotic components such as the chemical signatures of dominant plant species and mutualistic and pathogenic microbial populations. While patterns of local adaptation in individual species are widely recorded, the importance of microevolutionary processes for plant community assembly and function is poorly understood. 2. Here we examined how a history of long-term co-existence, and thus potential...

Data from: Dental data perform relatively poorly in reconstructing mammal phylogenies: morphological partitions evaluated with molecular benchmarks

Robert S. Sansom, Matthew Albion Wills & Tamara Williams
Phylogenetic trees underpin reconstructions of evolutionary history and tests of evolutionary hypotheses. They are inferred from both molecular and morphological data, yet the relative value of morphology has been questioned in this context due to perceived homoplasy, developmental linkage, and nonindependence of characters. Nevertheless, fossil data are limited to incomplete subsets of preserved morphology, and different regions are treated as equivalent. Through meta-analysis of 40 data sets, we show here that the dental and osteological...

Data from: Plant, soil and microbial controls on grassland diversity restoration: a long-term, multi-site mesocosm experiment

Ellen L. Fry, Emma S. Pilgrim, Jerry R.B. Tallowin, Roger S. Smith, Simon R. Mortimer, Deborah A. Beaumont, Janet Simkin, Stephanie J. Harris, Robert S. Shiel, Helen Quirk, Kate A. Harrison, Clare S. Lawson, Phil A. Hobbs & Richard D. Bardgett
The success of grassland biodiversity restoration schemes is determined by many factors; as such their outcomes can be unpredictable. There is a need for improved understanding of the relative importance of belowground factors to restoration success, such as contrasting soil type and management intensities, as well as plant community composition and order of assembly. We carried out an eight-year mesocosm experiment across three locations in the UK to explore the relative and interactive roles of...

Data from: Mechanisms and fitness effects of antibacterial defenses in a carrion beetle

Andres N. Arce, Paul R. Johnston, Per T. Smiseth & Daniel E. Rozen
Parents of many species care for their offspring by protecting them from a wide range of environmental hazards, including desiccation, food shortages, predators, competitors, and parasites and pathogens. Currently, little is known about the mechanisms and fitness consequences of parental defenses against bacterial pathogens and competitors. Here we combine approaches from microbiology and behavioural ecology to investigate the role and mechanistic basis of antibacterial secretions applied to carcasses by parents of the burying beetle Nicrophorus...

Data from: Competence increases survival during stress in Streptococcus pneumoniae.

Daniel J P Engelmoer & Daniel E Rozen
Horizontal gene transfer mediated by transformation is of central importance in bacterial evolution. However, numerous questions remain about the maintenance of processes that underlie transformation. Most hypotheses for the benefits of transformation focus on what bacteria might do with DNA, but ignore the important fact that transformation is subsumed within the broader process of competence. Accordingly, the apparent benefits of transformation might rely less on recombination than on other potential benefits associated with the broader...

Data from: Large brains and groups associated with high rates of agonism in primates

Veronica B. Cowl & Susanne Shultz
Animals living in social groups will almost inevitably experience competition for limited resources. One consequence of competition can be agonism, an activity that is not only costly to participate in at the individual level but potentially also at the group level due the detrimental effects that agonism can have on group stability and cohesion. Agonism rates across primate species have previously been associated with group size and terrestriality; therefore primates, particularly those in large groups,...

Data from: New species of Karydomys (Rodentia) from the Miocene of Chios Island (Greece) and phylogenetic relationships of this rare democricetodontine genus

Raquel López Antoñanzas, Pablo Peláez-Campomanes, Jêrome Prieto & Fabien Knoll
Karydomys is a rare and little diversified democricetodontine, of which only six species are currently recognized. This group of rodents is first recorded in the early Miocene (MN3) in China and spread quickly thereafter to Kazakhstan and Greece (MN4). Karydomys reached south‐western and central Europe by early middle Miocene times (MN5), from where it became extinct shortly thereafter (MN6). A new species of Karydomys is here described from the Miocene Keramia Formation of Chios Island...

Data from: Differences between hard and soft phylogenetic data

Robert S. Sansom & Matthew A. Wills
When building the tree of life, variability of phylogenetic signal is often accounted for by partitioning gene sequences and testing for differences. The same considerations however are rarely applied to morphological data, potentially undermining its use in evolutionary contexts. Here we apply partition heterogeneity tests to 59 animal datasets to demonstrate that significant differences exist between the phylogenetic signal conveyed by ‘hard’ and ‘soft’ characters (bones, teeth and shells versus myology, integument etc). Furthermore, the...

Data from: Phenotypic plasticity in response to environmental heterogeneity contributes to fluctuating asymmetry in plants: first empirical evidence

Branka Tucić, Sanja Budečević, Sanja Manitašević Jovanović, Ana Vuleta, Christian P. Klingenberg & Christian Peter Klingenberg
Fluctuating asymmetry (FA) is widely used to quantify developmental instability (DI) in ecological and evolutionary studies. It has long been recognized that FA may not exclusively originate from DI for sessile organisms such as plants, because phenotypic plasticity in response to heterogeneities in the environment might also produce FA. This study provides the first empirical evidence for this hypothesis. We reasoned that solar irradiation, which is greater on the southern side than on the northern...

Data from: A new family of Cambrian rhynchonelliformean brachiopods (Order Naukatida) with an aberrant coral-like morphology

Michael Streng, Aodhán D. Butler, John S. Peel, Russell J. Garwood & Jean-Bernard Caron
Tomteluva perturbata gen. et sp. nov. and Nasakia thulensis gen. et sp. nov., two new rhynchonelliformean brachiopod taxa, are described from carbonate beds from the lower middle Cambrian (Series 3, Stage 5) basinal Stephen Formation, Canada, and the upper lower Cambrian (Series 2, Stage 4) Henson Gletscher Formation, North Greenland, respectively. The two taxa are characterized by an unusual coral-like morphology typified by a high conical ventral valve with an anteriorly curved umbo and a...

Data from: Inter-specific gene flow dynamics during the Pleistocene-dated speciation of forest-dependent mosquitoes in Southeast Asia

Katy Morgan, Yvonne-Marie Linton, Pradya Somboon, Prasanta Saikia, Vas Dev, Duong Socheat & Catherine Walton
Tropical forests have undergone repeated fragmentation and expansion during Pleistocene glacial and interglacial periods, respectively. The effects of this repeated forest fragmentation in driving vicariance in tropical taxa have been well studied. However, relatively little is known about how often this process results in allopatric speciation, since it may be inhibited by recurrent gene flow during repeated secondary contact, or to what extent Pleistocene-dated speciation results from ecological specialisation in the face of gene flow....

Data from: REvoSim: organism-level simulation of macro and microevolution

Russell J. Garwood, Alan R. T. Spencer & Mark D. Sutton
Macroevolutionary processes dictate the generation and loss of biodiversity. Understanding them is a key challenge when interrogating the earth-life system in deep time. Model-based approaches can reveal important macroevolutionary patterns, and generate hypotheses on the underlying processes. Here we present and document a novel model called REvoSim (Rapid Evolutionary Simulator) coupled with a software implementation of this model. The latter is available here as both source code (C++/Qt, GNU General Public License), and as distributables...

Data from: A cross-lingual similarity measure for detecting biomedical term translations

Danushka Bollegala, Georgios Kontonatsios & Sophia Ananiadou
Bilingual dictionaries for technical terms such as biomedical terms are an important resource for machine translation systems as well as for humans who would like to understand a concept described in a foreign language. Often a biomedical term is first proposed in English and later it is manually translated to other languages. Despite the fact that there are large monolingual lexicons of biomedical terms, only a fraction of those term lexicons are translated to other...

Data from: The value of trophic interactions for ecosystem function: dung beetle communities influence seed burial and seedling recruitment in tropical forests

Hannah M. Griffiths, Richard D. Bardgett, Julio Louzada & Jos Barlow
Anthropogenic activities are causing species extinctions, raising concerns about the consequences of changing biological communities for ecosystem functioning. To address this, we investigated how dung beetle communities influence seed burial and seedling recruitment in the Brazilian Amazon. First, we conducted a burial and retrieval experiment using seed mimics. We found that dung beetle biomass had a stronger positive effect on the burial of large than small beads, suggesting that anthropogenic reductions in large-bodied beetles will...

B.B. Phillips, R.F. Shaw, M. Holland, E.L. Fry, R.D. Bardgett, J.M. Bullock & J.L. Osborne
The floral resources provided to pollinators by different sown plant experimental plant communities were assessed under ambient and experimental drought conditions. The dataset includes the abundance and diversity of floral resources in all plant communities and more detailed information on the nectar quality and quantity provided by three focal plant species. Pollinator visit surveys were carried out on selected plots. These data can be linked to the related 'Ecosystem functions and vegetation data for Winklebury...

Metaschoepite dissolution in sediment column systems – groundwater/soil geochemistry and uranium X-ray spectroscopy data

W. Bower, K. Morris, F.R. Livens, J.F.W. Mosselmans, C.M. Fallon, A.J. Fuller, L.S. Natrajan, C. Boothman, J.R. Lloyd, S. Utsunomia, D. Grolimund, D. Ferreira Sanchez, T. Jilbert, J.E. Parker, T. Neill & G. Law
This dataset contains the results of a laboratory study investigating the dissolution of UO3•nH2O particles in dynamic sediment/groundwater column systems, representative of the shallow subsurface at the Sellafield Ltd. site, UK. Measurements were carried out to determine the extent of uranic particle dissolution and the speciation of dissolved uranium within the columns under contrasting biogeochemical conditions (oxic and electron-donor amended). Columns effluents were analysed periodically for key biogeochemical indicators (nitrate, sulfate) and trace metals (iron,...

Closure investigation on cloud condensation nuclei ability of processed anthropogenic aerosols

Dawei Hu
Whether the cloud condensation nuclei (CCN) ability of aerosol could be predicted by compositions has been long debated. Measurements of sub-micron aerosol compositions and size-resolved CCN activation fraction were conducted at a mountain site (1344 m) near Beijing region during wintertime. The site was influenced in the noon-afternoon by ground anthropogenic sources through convective mixing (CM) and for certain period received aged pollutants by regional advection (RA). By comparing the measured CCN-derived hygroscopicity parameter (κCCNc)...
