Data from: Phenology of farmland floral resources reveals seasonal gaps in nectar availability for bumblebees

Thomas P. Timberlake, Ian P. Vaughan & Jane Memmott
Floral resources are known to be important in regulating wild pollinator populations and are therefore an important component of agri‐environment and restoration schemes which aim to support pollinators and their associated services. However, the phenology of floral resources is often overlooked in these schemes – a factor which may be limiting their success. Our study characterises and quantifies the phenology of nectar resources at the whole‐farm scale on replicate farms in Southwestern UK throughout the...

Data from: Plant species roles in pollination networks: an experimental approach

Kate Pereira Maia, I.P. Vaughan & Jane Memmott
Pollination is an important ecosystem service threatened by current pollinator declines, making flower planting schemes an important strategy to recover pollination function. However, ecologists rarely test the attractiveness of chosen plants to pollinators in the field. Here, we experimentally test whether plant species roles in pollination networks can be used to identify species with the most potential to recover plant-pollinator communities. Using published pollination networks, we calculated each plant’s centrality and chose five central and...

Fractional frequency shift data for a additive manufactured cylindrical microwave resonant cavity between 6 - 450 K, for the assessment of thermal expansion coefficient

Richard Gumbleton, Jerome A Cuenca, Georgina M Klemencic, Nick Jones & Adrian Porch
The relatively poor microwave electrical conductivity of additive manufactured AlSi10Mg results in many applications relying on the use of post processing in the form of silver plating. For space & satellite application, extreme thermal cycling can cause expansion of the component and the silver plating at different rates. In addition to this, extreme thermal expansion of the component can lead to changes in operating frequency. Therefore, assessment of the thermal properties of AlSi10Mg is of...

An indicator-based problem reduction scheme for coupled reactive transport models - dataset

Brubeck L Freeman, Peter Cleall & Anthony D Jefferson
A significant number of transport models have been developed for the simulation of chemical transport in porous media. However, the computational cost can become prohibitively expensive when a problem comprises multiple chemical species; particularly if transport is considered within a significant domain over a long time period. This dataset contains the results produced by a numerical model employing a new indicator-based multi-order problem reduction scheme (PRS) that adresses this issue, as well as those of...

New insights for the valorisation of glycerol over MgO catalysts in the gas-phase - dataset

Louise R Smith, Paul J Smith, Karl S Mugford, John Mark Douthwaite, Nicholas F Dummer, David J Willock, Mark Howard, David W Knight, Stuart H Taylor & Graham J Hutchings
Glycerol, a waste product from bio-diesel production can be transformed over catalysts to methanol and other products without the need for gaseous hydrogen. Representative datasets compliment the published data contained in the table and figures. These include the chromatograms which show the components of the reaction mixture, thermal gravimetric analysis of used catalysts to show the release of carbon build up and X-ray diffraction patterns of the catalysts to show their structural identity. The chromatograms...

Privacy Risk Awareness when Sharing Location Information on Online Social Networks

Alia I Abdelmoty & Fatma S Al-Rayes
The result of a study involving 715 anonymous participants. The study is in the form of 10 scenarios in which participants were asked to say how likely they were to share their location. The study also involved the participants' responses to open-ended questions in which they were able to justify their sharing decisions and add additional information about their sharing habits.

Binding Modes of Carboxylic Acids on Cobalt Nanoparticles - dataset

Barbara Farkas, Umberto Terranova & Nora H De Leeuw
In order to study binding modes of carboxylic acid on cobalt nanoparticles, optimal system size has to be assesed through structural, energetical, and electronical properties. Density functional theory (DFT) theoretical simulation datasets are available in the .xlsx format (can be viewed either by MS Office or Libre Office) comprising 8 data sheets, with first 5 sheets corresponding to the structural properties of cobalt clusters of varying sizes (N=6, 13, 19, 30, 57, 76, 153, 323)...

Investigating the influence of reaction conditions and the properties of ceria for the valorisation of glycerol - dataset

Louise Smith, Paul J Smith, John M Douthwaite, Nicholas F Dummer, Graham J Hutchings, Stuart H Taylor, Mark Howard, David J Willock & David W Knight
The dataset contains representative gas chromatography, X-ray diffraction, thermal analysis, Raman spectroscopy and nitrogen adsorption isotherms. These illustrate the textural properties of the ceria under investigation and the influence of changing syntheis conditions on the formation of reaction products from glycerol. The conclusions in the paper describe the ceria surface area and defect sites as having little influence on the reaction outcomes.

Density functional theory calculations and classical molecular dynamics simulations to study the mobility of phenol in purely siliceous and acidic zeolite Beta. The data contains: the DFT-optimized coordinates of phenol in acidic zeolite Beta (text files) mean-square displacement averaged over 6 ns of MD simulations at the temperatures 393, 418 and 443 K (text files) diffusion coefficients of translation and rotation at the temperatures 393, 418 and 443 K, and the respective activation energies of...

Temperature Correction Using Degenerate Modes for Cylindrical Cavity Perturbation Measurements - dataset

Michael Barter, Samuel L Partridge, Daniel R Slocombe & Adrian Porch
A common method to correct for this is to use another resonant mode separate to the measurement mode which is not affected by the sample. Instead of using independent modes this paper describes a method to use split degenerate TMm10 modes. TMm10 consists of two modes with identical field patterns with a relative rotation between them and identical resonant frequencies. A strategically placed perturbation reduces the frequency of one of the TMm10 modes and affects...

Data from: Evidence to support common application switching behaviour on smartphones

Liam Turner, Roger Whitaker, Stuart Allen, David Linden, Kun Tu, Jian Li & Don Towsley
We find evidence to support common behaviour in smartphone usage based on analysis of application (app) switching. This is an overlooked aspect of smartphone usage that gives additional insight beyond screen time and the particular apps that are accessed. Using a dataset of usage behaviour from 53 participants over a 6-week period, we find strong similarity in the structure of networks built from app switching, despite diversity in the apps used, and the volume of...

Data from: Multiscale patterns of rarity in fungi, inferred from fruiting records

Alan C. Gange, Lewis P. Allen, Aline Nussbaumer, Edward G. Gange, Carrie Andrew, Simon Egli, Beatrice Senn-Irlet & Lynne Boddy
Aim: It is unknown whether fungi show similar trends to other organisms in their macroecological patterns of abundance and spatial distribution. Here, we investigated fungal abundance-occupancy relationships to determine whether fungi that are common at a local scale tend to be more widely distributed. Location: UK and Switzerland Time period: 1950 - 2014 Major taxa studied: Fungi Methods: We used a local dataset of fruiting records of 2,319 species in the UK, accumulated over 65...

The data described here are the ASCII files containing the Bader charges, magnetic moments, partial density of states, electronic conductivity at different temperatures, mean square displacement that...

Predicting hedgehog mortality risks on British roads using habitat suitability modelling

Patrick Wright, Frazer Coomber, Fiona Mathews, Sarah Perkins & Chloe Bellamy
Road vehicle collisions are likely to be an important contributory factor in the decline of the European hedgehog (Erinaceus europaeus) in Britain. Here, a collaborative roadkill dataset collected from multiple projects across Britain was used to assess when, where and why hedgehog roadkill are more likely to occur. Seasonal trends were assessed using a Generalized Additive Model (GAM). There were few casualties in winter — the hibernation season for hedgehogs — with a gradual increase...
