title: Visible light images of a mature oak woodland canopy under Free-Air CO2 Enrichment at the BIFoR-FACE experimental site, Staffordshire, UK, 2021-2023

description: The dataset provides visible light images from a camera at the Birmingham Institute for Forest Research Free Air CO2 Enrichment (BIFoR-FACE) experimental site from July 2021 to September 2023. The data are visible light images, predominately of tree canopies (leaves, branches, stems). 

This site is a mature oak woodland, and the field of view of the camera includes one of the experimental CO2 enrichment plots, and numerous trees in the ambient un-enriched air. The trees included in the field of view are predominantly Quercus robur, with some individuals of Acer pseudoplatanus and Pinus sylvestris. 

Data were collected to complement additional data on canopy temperature at the same site but can also be used to look at vegetation phenology. 
description: Data were collected using a LabView program to control the camera. Data were initially stored on a local PC, and then transferred to a University of Plymouth network server. Data provided are the raw output from the camera.

title: Social perceptions on Pinus radiata invasion and the influence of fire occurrence in Central Chile, 2023-2024

description: This dataset was constructed to understand the perceptions of respondents about pine tree invasion in three communes in central-southern Chile: Santa Juana, Constitución and Tucapel. In addition, the factors that influence the perception of the species and the interest of each community to participate in community control strategies were identified. Face-to-face interviews were conducted in two communities affected by megafires (Santa Juana and Constitución) and one community not affected by such an event (Tucapel), in order to check if there are differences in the willingness of the respondents.

The variables evaluated include: 
  (a) demographic data; with information on location, gender, education, age, economic activities and sectors of the respondents; 
  (b) beliefs; whether they think that alien species damage the ecosystem; benefit people; and whether they think that the pine tree harms the traditions of the community; 
  (c) what uses they give to wild pine trees; as fuel, construction material, economic, recreational and cultural purposes; 
  (d) relationship between pine trees and forest fires; if they think that wild pine favours intense and frequent fires, if all vegetation has the same fire risk, and if they think that pine trees can grow back easily after fires, and 
  (e) responsibilities associated with management; if they have ever controlled wild pine in their sector, personal, community, business and government responsibilities associated with management, and how likely they are to participate in strategies to control wild pine. 

Data were collected between November 2023 and January 2024.
description: Face-to-face interviews were conducted, with 62 surveys collected in Santa Juana, 78 in Constitución, and 80 in Tucapel, making a total of 220 surveys. 

ArcGIS and Google Earth Pro were utilized to select populated rural sectors. The areas visited represent different rural areas of each commune where people over 18 were invited to participate in the survey. To prevent any bias, neutral language was used when approaching the species, and the survey instrument was approved by the ethics committee of the Universidad de Concepción (CEBB 1567-2023).

title: Bulk elemental and stable isotope composition of organic matter from terrestrial, intertidal, and marine environments, UK, 2016-2021

description: Bulk elemental (carbon and nitrogen) and stable isotope (delta 13C and delta 15N) data produced from 491 samples collected between 2016-2021 from terrestrial (soil, peat, living biomass, dead biomass), intertidal (saltmarsh vegetation, saltmarsh roots, seagrass biomass, mudflat, faecal matter) and marine (macroalgae, microalgae zooplankton, finfish aquaculture waste) environments across the UK. 

These samples alongside analytical standard derived from natural materials (lignin, humic acid, cellulose, glucose, protein) were analysed to determine their bulk elemental (organic carbon and nitrogen) and stable isotope (delta 13C org and delta 15N) composition. These values are envisioned to be used to constrain organic carbon sources (terrestrial vs marine) in the natural environment when used alongside isotope mixing models. 

The work was carried out under the NERC programme - Carbon Storage in Intertidal Environment (C-SIDE), NERC grant reference NE/R010846/1.
description: Samples were collected from coastal catchments around the United Kingdom, the material was described in the field using expert knowledge. The samples were stored at -20°C prior to analysis. The samples were oven dried at (40°C for 72 hours) prior to being milled to a fine powder. Bulk elemental (OC and N) and stable isotope (delta 13C org and delta 15N) composition was determined following the standard methodology detailed in the supporting documentation.  All laboratory equipment were calibrated in accordance with the laboratory practises at the University of St Andrews. Results were recorded on to lab sheets and transferred into an Excel file. Results were exported as comma separated value (.csv) files for ingestion into the EIDC.

title: Surface temperature, surface oxygen, water clarity, water chemistry and phytoplankton chlorophyll a data from Derwent Water, 1990 to 2013

description: This is a long-term monitoring dataset of surface temperature, surface oxygen, water clarity, water chemistry and phytoplankton chlorophyll a from fortnightly sampling by the Centre for Ecology & Hydrology (and previously the Institute of Freshwater Ecology) at Derwent Water in Cumbria, England. The data available to download comprise surface temperature (TEMP) in degree Celsius, surface oxygen saturation (OXYG) in % air-saturation, Secchi depth (SECC) in metres, alkalinity (ALKA) in µg per litre as CaCO3 and pH. Ammonium (NH4N), nitrate (NO3N), soluble reactive phosphate (PO4P), total phosphorus (TOTP), dissolved reactive silicon expressed as SiO2 (SIO2) and phytoplankton chlorophyll a (TOCA) are all given in µg per litre.  Measurements are made from a boat at a marked location (buoy) at the deepest part of the lake. When it was not possible to visit the buoy, samples were taken from the shore, thus water samples were not integrated on these occasions, marked as Flag 2. All data are from August 1990 until the end of 2013.

title: Organic carbon burial calculation using sediment trap and sediment core records from Rostherne Mere, Cheshire, UK (1360-2016)

description: This dataset includes sediment trap, sediment core and loss-on-ignition to total organic carbon measurements from a PhD research project at Rostherne Mere in Cheshire. These data were collected to show the relationship between the changing nutrient loads and subsequent organic carbon burial over the last 120 years. The sediment trap data cover the period from May 2010 to August 2016, while the sediment core was taken in September 2011 and has been 210Pb dated to circa 1360AD. All data is presented for date, loss-on-ignition (LOI) and calcium carbonate (CaCO3), with sediment trap data converted into net flux measurements and sediment core data calculated for net sedimentation rate following 210Pb dating. The conversion from LOI to total organic carbon was measured using mass spectrometry and applied to the trap and core data. The work was carried out as part of a Natural Environment Research Council (NERC) funded PhD [grant number NE/L002493/1], with part of the work also funded by the NERC small grant [grant number NE/H011978/1].
description: Sediment trapping using two sequencing traps at 10 m and 25 m water depth was carried out at Rostherne Mere from May 2010 to September 2016. The traps sequentially opened into 12 individual 250 ml HDPE bottles, each representing a two-week collection period (except in January and February longer collection periods of up to four weeks were used). The traps were reset every six months as dictated by the trapping interval used, with trap sediment kept cool, dark and sealed during transport to the laboratory where it was stored frozen prior to analysis. A 112cm long sediment core was collected at 26 m water depth in September 2011 using a Livingstone piston corer. The sealed core was transported vertically to the laboratory, and stored vertically in a dark cold room at 5°C, prior to extrusion at 1cm intervals for the upper 50cm of sediment, and then at 0.5cm intervals for the remainder of the core. Mass-spectrometry elemental analysis was conducted for 23 sediment samples from a combination of sediment core and sediment trap sources. A range of organic matter percentage (OM%) samples were selected to generate an estimated OM to total organic carbon (TOC) conversion, specifically for application to Rostherne Mere sediment samples. The data was collated to Excel spreadsheets held by the lead author at Loughborough University. For ingestion into the Environmental Information data was extracted from the Excel spreadsheets and converted into a comma separated file.

title: Survival and persistence of clinically relevant strains of toxigenic Vibrio cholerae on plastic and vegetation, under environmentally relevant conditions

description: This dataset contains information relating to the survival and persistence of clinically relevant strains of toxigenic Vibrio cholerae on plastic and vegetation, under environmentally relevant conditions. The data encompass bacterial strain identity, material type, timepoints (days), bacterial concentration (CFU/ml) and survival percentages. Data were sampled over a 28-day period using culture-based approaches; and the ability of isolates to cause disease following their recovery was determined through the use of a Galleria mellonella model. The ability of isolates to persist on materials, dissociate from materials into water bodies, and recolonise materials was also determined.

This work was supported by the UKRI Natural Environment Research Council (NERC) as part of the GCRF SPACES project [grant number NE/V005847/1] and the Plastic Vectors project, “Microbial hitch-hikers of marine plastics: the survival, persistence & ecology of microbial communities in the ‘Plastisphere’” [grant number NE/S005196/1].
description: Data were generated through laboratory experiments investigating the persistence, virulence, and survival of clinically relevant strains of toxigenic Vibrio cholerae. Bacteria were cultured on materials (Polyethylene [PE], polypropylene [PP] and banana leaf [BL]) and analysed for persistence over time (up to 28 days) and virulence using Galleria mellonella larvae. Materials (PE, PP and BL) were prepared and inoculated under controlled laboratory conditions. V. cholerae strains were inoculated onto materials in nutrient-rich and surface water environments. Sampling was taken at defined time points (7, 14, 21, 28 days). G. mellonella larvae were used to evaluate virulence, and survival was assessed over 72 h. The experiments utilised standard laboratory equipment such as 96-well plates and incubators. G. mellonella larvae were sourced from a local supplier and used within one week of delivery. Instrumentation used for bacterial enumeration, including the plate reader, was calibrated according to standard laboratory protocols. The data underwent rigorous quality control through replication (biological triplicates), statistical analysis (ANOVA), and controlled experimental conditions (e.g., temperature and material consistency). Statistical methods including ANOVA and Tukey’s post-hoc tests were applied to assess treatment effects and survival outcomes.

title: Simulated monthly biological indicators for England and Wales 1964-2012

description: Monthly time series of simulated de-trended/de-seasonalised biological indicators at 86 bio-monitoring sites in England and Wales based on the modelled response of these indicators to discharge (represented by a standardised streamflow index, SSI) at 76 paired gauging stations. The biological indicators include: 

(i) Average Score per Taxon (ASPT)
(ii) Lotic-invertebrate Index for Flow Evaluation (LIFE) calculated at family-level (LIFE Family)
(iii) LIFE calculated at species-level (LIFE Species). 

The simulation spans the period 1964-2012.
description: Biological indicator ASPT and LIFE (family and species levels) were obtained for 86 sites from the EA Freshwater and Marine Biological Surveys for Invertebrates England database (commonly known as 'BIOSYS'). Biological records for the UK typically exhibit an annual positive trend and seasonal offset (higher values in spring); bio-indicators were therefore de-trended and de-seasonalised by fitting linear regression models (season and year as predictors) then subtracting the fitted bio-indicator values from the raw indicator data. Monthly SSI series for period 1964-2012 for the 76 gauging stations paired to the 86 BIOSYS sites were derived using 6-month accumulation period and Tweedy distribution. Seven predictors were assembled: SSI on same monthly date as biological indicators, and six lagged SSI (6, 12, 18, 24, 30, and 36 months prior to date of biological indicators). For each bio-indicator, a model of the indicator's response to the SSI predictors was fitted using Multi-Level modelling and Multi-Model Inference. Models were then run with the whole SSI dataset to produce the final dataset of simulated de-trended/de-seasonalised ASPT, LIFE Family and LIFE Species series for period 1964-2012.

title: Carbon and nitrogen content of permafrost soils from the North West Territories and Yukon, Canada, 2019-2020

description: This dataset contains information on the carbon and nitrogen content of varying permafrost soil types and layers sampled from the North West Territories and Yukon, Canada in 2019 and 2020. Samples analysed include turbels, orthels and histels from drained lakes, non-lake (alluvial and till) and yedoma deposits including active layer and both organic and mineral permafrost (where appropriate). 
description: The soil samples were collected by digging soil pits, coring or horizontal drill holes into thaw slumps and recording the sampling location via GPS. Frozen soil samples were shipped to Exeter where they were defrosted, manually homogenised by mixing, subsampled and oven dried, then ground and weighed out for CN elemental analysis in June 2021. The elemental standard and check standard used was EDTA every ten samples.

title: Marsh Tit (Poecile palustris) territory surveys in English woods during 2002-2020

description: The dataset records the annual number of occupied Marsh Tit breeding territories in 74 individual woods and woodland patches in 14 English counties for variable periods between 2002 and 2020. Different woods were surveyed from between one spring period and for up to 17 annual springs. Territory counts were derived from a standard highly-repeatable survey methodology or from more intensive population studies that produced high quality results. Marsh Tits are a small (10 g) songbird that are specialists of mature deciduous and mixed woodlands and have undergone a substantial population decline in Britain over recent decades. Because of their large territories, Marsh Tits are difficult to monitor by passive surveys, and so these specific and more accurate methodologies were used. This data can be used to compare with other woods using the same or a comparable methodology, investigate population trends or population-habitat relationships, or to monitor population change in future repeat surveys of the same woods. The data is georeferenced and each of the 237 individual records provides the Great Britain Ordnance Survey (OSGB) National Grid x and y coordinates of the surveyed wood, and also the woodland area surveyed, name and location (county name) of the wood, year of survey, woodland type and survey method.
description: Surveys took place in early spring (February to April) just prior to nesting and represent the number of breeding territories in each wood. Woods were surveyed for between 1 and 17 consecutive years from 2002 to 2020. A playback survey method was the primary method used, see Broughton et al. (2018) for full details. Some woods were also surveyed with colour-ringing during detailed population projects, involving intensive marking and re-sighting/recapture, see Broughton et al. (2010) for this methodology.

Almost all surveys involved the entire woodland patch, but two large woods were only partially surveyed. These are indicated in the dataset. The territory counts for each wood are considered to be very reliable. The playback methodology was quality control tested (details in Broughton et al. 2018) and found to locate a mean 96% of birds present with a consistent estimate of territory numbers, although underestimates of approximately 10% may occur for larger woods (>70 ha).
