title: Sulphur and nitrogen atmospheric Concentration Based Estimated Deposition (CBED) data for the UK 2015-2017

description: These datasets provide Concentration Based Estimated Deposition (CBED) values of sulphur and nitrogen atmospheric deposition for 5x5 kilometre (km) grid squares of the UK averaged over the years 2015 to 2017.

The data consist of deposition values for sulphur, oxidised nitrogen and reduced nitrogen, and base cations. Total deposition is the sum of four components calculated separately: wet deposition, dry deposition of gases, dry deposition of particulate matter and cloud droplet deposition.

Habitat-specific data are provided for (i) moorland/short vegetation everywhere, and (ii) forest everywhere. Additionally, the grid square average over multiple land cover types (i.e. arable, grassland, forest, moorland, urban) is also calculated. The habitat-specific data are recommended for use with critical loads for the calculation of critical load exceedances. The work in generating and compiling the dataset has been funded by the UK Centre for Ecology & Hydrology (UKCEH) and various Department for Environment, Food & Rural Affairs (Defra) contracts. 
description: The Concentration Based Estimated Deposition (CBED) methodology generates 5x5 km resolution maps of wet and dry deposition of sulphur, oxidised and reduced nitrogen, and base cations from measured concentrations of gases and particulate matter in air and measured concentrations of ions in precipitation. These data are collected at sites in the UK Eutrophying and Acidifying Pollutants (UKEAP) network.  The site-based measurements are first interpolated to generate maps of concentrations for the UK.  The ion concentrations in precipitation are combined with an annual precipitation map from the UK Meteorological Office to generate values of wet deposition.  Gas and particulate matter concentration maps are combined with spatially distributed estimates of habitat-specific deposition velocities to generate dry deposition for 5 land cover categories: forest, moorland, grassland, arable and urban.  The deposition to the 5 land cover categories are combined, depending on the relative proportions of different land cover categories in the 5x5 km grid square, to generate values for grid square averaged deposition.  Dry deposition includes deposition of gases (Sulphur Dioxide (SO2), Nitric Acid (HNO3), Nitrogen Dioxide (NO2) and Ammonia (NH3) and particulate matter (sulphate, nitrate, ammonium, calcium and magnesium) to vegetation.  For critical load exceedance calculations, deposition values for moorland are applied to all non-woodland habitats, and deposition values for forest are applied to all woodland habitats.

Data processing was done using the GenStat programme and results output as text files. These were then exported as comma separated values for ingestion into the Environmental Information Data Centre.

title: Soil properties across primary forest, logged forest and oil palm plantation in Sabah, Malaysia

description: Data comprise soil properties and soil nutrients across unlogged and logged tropical forests in Sabah, Malaysia. Soil properties (ID, Site, Land_Use, Plot_Name, Subplot, Horizon, pH, Total_C, Total_N, Total_P, inorganic_P, C:N, Sand, Silt, Clay) measured in soil samples and soil nutrients (Identifier, Site, Land_Use, Plot_Name, Subplot, NO3_N, NH4_N, Total_N, Ca, Mg, K, P, Fe, Mn Cu, Zn, B, S, Pb, Al, Cd) extracted from buried ion exchange membranes sampled between March and April 2015 and measured at Forest Research Centre, Sabah, Malaysia. This data is  a contribution from the UK NERC-funded Biodiversity And Land-use Impacts on Tropical Ecosystem Function (BALI) consortium (http://bali.hmtf.info).
description: Eight 1-hectare plots were located across three sites representative of unlogged or logged tropical forest; Danum Valley Conservation Area (DVCA), Maliau Basin Conservation Area (MBCA) and SAFE project in Sabah, Malaysia (Riutta et al. 2018). A stratified sampling design was utilised. 1 Ha plots were first subdivided into twnety-five 20x20 m subplots with five of these randomly selected for sampling.

Soil nutrients data: at three locations within each subplot, four pairs of PRS™ ion exchange membranes (www.westernag.ca) (one pair = 1 cation & 1 anion) were buried vertically to approx 10cm depth. These were left in situ for two weeks, removed, washed with deionised water and shipped to the manufacturer (Western Ag, Canada) for analysis. The four probe pairs from each location were pooled prior to elution with 0.5M HCl for one hour. NO3- and NH4+ were measured colorimetrically using automated flow injection analysis (FIA). All other elements were analysed using inductively coupled plasma –optical emission spectroscopy (ICP-OES). Results are reported as supply rates over the burial period (µg/10cm2/14 days). 

Soil properties data: Five samples were collected from each subplot using a gouge augur. The organic layer depth was measured and then horizons (organic and mineral soil) were separated and sealed in Ziploc bags. The five samples from each subplot were pooled prior to analysis to yield 20 organic and 20 mineral soil samples per forest type (Unlogged and logged forest). pH was measured on fresh soils in a 2.5:1 water suspension (Landon, 1984). Total C and N was measured using an elementar vario max CN analyser. Total P was extracted using a sulphuric-nitric-perchloric acid digest (Allen, 1989) whilst inorganic P was extracted using a Bray No. 1 solution (Bray and Kurtz. 1945). Concentration was measured on a spectrophotometer at 880nm (Anderson & Ingram, 1993). Sand silt and clay were determined using the pipette method. References available from supporting documentation.

title: Home range size and habitat availability data for 39 individual European nightjars on the Humberhead Peatlands NNR from 2015-2018

description: This dataset contains home range size, habitat availability and selection ratio data, calculated from GPS data fixes collected from individual European nightjars, in four concurrent years (2015-2018). Home ranges are 95% areas of use, presented in hectares. Habitat availability data are presented as the percentage (%) of each habitat category (n = 6, pooled from 14 original habitat types) available to each individual within their 95% home range. Selection ratios are Manly Selection Ratios for 14 habitat types and express the extent to which each habitat type is used by each individual bird, compared to how much of it is available. Selection Ratios >1 express positive selection – i.e. used more than expected, given availability. Selection Ratios <1 express avoidance – i.e. used less than expected, given availability.
description: The metadata accompanying the data contains GPS data points (WGS84 format) from 39 European nightjars (Caprimulgus europaeus). The data contains additional information on identity of the bird, date and time of fix acquisition. These data were collected on the Humberhead peatlands NNR, South Yorkshire, from 2015 until 2018. Birds were caught in mist nets and tail-mounted miniaturised GPS tags (Pathtrack, Otley, UK; <3% bird bodyweight) were fitted by BTO-licensed researchers. 

Data were collected as part of a NERC ACCE-funded PhD.

title: Antibiotic resistant gene abundance in fresh cattle faeces from the North Wyke Farm Platform

description: The data consists of the abundance of antibiotic resistant genes (ARG) in fresh cattle faeces from faecal samples taken from a cohort of 30 cattle. The cattle were from the North Wyke Farm Platform, a UK national capability, located at Rothamsted Research, North Wyke in Devon. Faecal samples were collected in November 2016. The cohort of 30 cattle were selected from 90 animals, ten from each of the three farmlets. Samples were collected from cattle as they entered housing for the winter, i.e. at weaning.
description: Faecal samples were taken by members of staff from Rothamsted Research North Wyke. In the laboratory faecal samples were pooled, such that for each farmlet (10 cattle) there were 3 samples, (3, 3, 4 cattle). This resulted in 9 faecal samples from which DNA was extracted using a commercially available extraction kit (MO BIO PowerSoil® DNA Isolation kit (catalogue No. 12888-100). The following adaption to the Power Soil protocol; at sample preparation samples were heated to 65 °C for 10 minutes prior to vortex. DNA was sequenced by the sequencing unit at the University of Exeter. The resulting metagenomic data was analysed at the Environmental Biotechnology Laboratory at the University of Hong Kong.

The establishment licence under which the experiment was conducted was XA11784A2 and the project licence was P592D2677.

Data was collected for the NERC funded “Does the potential for AMR selection differ between common UK cattle grazing systems?” NE/N019792/1.

title: Photosynthesis of Trifolium repens versus Lolium perenne after ozone exposure in solardomes

description: The dataset consists of ACi (net CO2 assimilation rate, A, versus calculated substomatal CO2 concentration, Ci) curve data from an ozone experiment during which Trifolium repens and Lolium perenne were exposed as both monocultures and two-species mixtures to an episodic rural ozone regime in large, well-watered containers within solardomes for 12 weeks. Treatments were elevated ozone (AOT40 (Accumulated Ozone Threshold exposure of 40 parts per billion) of 12.86 ppm h) or control conditions (AOT40 of 0.02 ppm h). ACi curves were carried out mid-way and at the end of the exposure period using a Portable Photosynthesis System, CIRAS (PP-Systems) to calculate the photosynthetic parameters Jmax (maximum rate of photosynthetic electron transport) and Vcmax (maximum rate of Rubisco carboxylase activity). The observed decreases in photosynthetic efficiency and capacity in elevated ozone indicate that the ability of such ubiquitous vegetation to act as a sink for atmospheric carbon may be reduced in future climates. The experiment was carried out at the CEH Bangor Air Pollution Facility. This work was funded by the Centre for Ecology & Hydrology Integrating Fund Initiative.
description: Trifolium repens and Lolium perenne were exposed as both monocultures and two-species mixtures to an episodic rural ozone regime in large, well-watered containers within solardomes for 12 weeks. Treatments were elevated ozone (AOT40 of 12.86 ppm h) or control conditions (AOT40 of 0.02 ppm h). After 6 weeks there was decreased photosynthetic capacity for T. repens, however, by the end of the exposure there was also decreased photosynthetic capacity of L. perenne, a species previously considered insensitive to ozone. The observed decreases in photosynthetic efficiency and capacity in elevated ozone indicate that the ability of such ubiquitous vegetation to act as a sink for atmospheric carbon may be reduced in future climates. ACi curves were carried out mid-way and at the end of the exposure period using a Portable Photosynthesis System, CIRAS (PP-Systems).

title: Levels of the pheromone 7,11-heptacosadiene in the sibling species Drosophila simulans and Drosophila sechellia

description: This dataset provides measurements of the cuticular pheromone, 7,11-heptacosadiene of individual female vinegar flies. The purpose of the dataset is to compare the levels between two sibling species, Drosophila simulans and Drosophila sechellia. Single female virgins were isolated from males at eclosion, aged five days, and then washed in hexane to extract cuticular hydrocarbons. The extracts were analyzed by gas chromatography relative to an internal standard. 
description: Drosophila females that were five days old were anaesthetised on ice for ten minutes. Individual female flies were then transferred to 150uL pure HPLC grade hexane within a 200uL glass vial that was fitted with a glass insert. The vial with the fly inside was vortexed to extract the hydrocarbons. Afterwards the fly was removed, the hexane extract was dried down under a gentle flow of nitrogen, and the vial was shipped to Groningen for gas chromatograph analysis. The retention time in minutes of each peak relative to an internal standard (C26), was used to measure size and identify 7,11-heptacosadiene. The area underneath each peak, relative to the standard was used to measure the quantity of 7,11-heptacosadiene. ChemStation software (Agilent technologies) was used to estimate area under the peak.
