title: Time series of uranium transformations in aerobic soils following experimental addition of uranyl ion

description: The data comprise measurements of the 'soluble', 'chemically exchangeable' and 'isotopically exchangeable' U concentrations in a diverse set of soils following experimental addition of UO22+ and incubation in the laboratory under controlled temperature conditions for ca. 1.7 years.

The long term behaviour of U in aerobic soils was studied by conducting a laboratory-based experiment in which a set of twenty topsoils from central England with contrasting properties (e.g. pH, organic matter content, land use) were contaminated with a solution containing UO22+ in soluble form and incubated in the dark, in a moist but aerobic condition, at a temperature of 10 deg C for 619 days. The transformations of U in each soil microcosm were periodically monitored by means of soil extractions conducted on subsamples of incubated soils.

The resulting dataset enabled quantification of the kinetics of UO22+ transformations in aerobic soils and the relationships with soil properties and land uses (arable, grassland and moorland/woodland). The dataset will be useful in developing models of long-term U bioavailability in aerobic soils under temperate conditions. 
description: At each sampling time, a portion of ca. 4g soil from each microcosm was equilibrated with 0.01 M KNO3 to quantify the soluble U. The chemically exchangeable and isotopically exchangeable fractions of U were determined by equilibrating another portion of ca. 2g soil with 1 M Mg(NO3)2 containing a known amount of the isotopic tracers 233UO22+ and 236UO22+. Soil extracts were analysed using a Thermo Fisher Scientific iCAP-Q ICP-MS.

title: Nitrogen fixation and phosphatase activity of 97 nitrogen-fixing and non-fixing trees in Panama

description: This data includes information about nitrogen fixation, phosphatase activity, plant nitrogen and phosphorus demand and soil nitrogen and phosphorus availability of nitrogen-fixing and non-fixing trees from seven species grown in an experimental plantation at the Agua Salud Native Species Plantation, El Giral, Panama (9°12'50.15''N, 79°43'26''W). Data were collected by the Smithsonian Tropical Research Institute and Princeton University and were analysed by the University of Leeds.

This work was funded by the following organisations: Heising-Simons Foundation, Hoch Family, ForestGEO®, HSBC, Stanley Motta, Small World Institute Fund, Smithsonian Institution's Competitive Grants for Science, Smithsonian Institution's Grand Challenges, National Science Foundation (award reference: EAR-1360391), National University of Singapore, Smithsonian Tropical Research Institute, Yale-NUS college, Princeton University, Princeton Environmental Institute, Princeton Carbon Mitigation Initiative, University of Leeds and NERC (award reference: NE/M019497/1)
description: The dataset includes the original values for all variables except nitrogen fixation and phosphatase activity, which represent the mean across replicates within a tree (three replicates for fixation rate, five replicates for phosphatase activity). Data have not been transformed and no outliers were removed.

Nitrogen fixation was measured using three approaches: (1) To measure nodule biomass, six 5.5 cm diameter soil cores were taken from within two meters of the base of the tree and examined for root nodules in the lab. (2) To measure rates of fixation within the nodules of the majority of trees, nodules were excavated from fine roots at the base of each tree and acetylene reduction assay was conducted immediately. (3) To obtain the conversion of acetylene reduced to nitrogen fixed, nodules were excavated from fine roots at the base of a subset of trees and were incubated with labeled 15N and later analysed with isotope ratio mass spectrometry to determine the nitrogen fixed relative to non-enriched control nodules for each tree. Data were expressed as nodule biomass, nitrogen fixation rate converted to grams nitrogen fixed per area of rooting zone of the focal tree.

title: Coastal Biodiversity and Ecosystem Service Sustainability (CBESS) the erosion rate of sediment cores from salt marsh sites at Morecambe Bay and Essex

description: The dataset comprises the erosion rate (percent mass loss per hour) observed in sediment cores (16 centimetre (cm) diameter, 30cm height) subjected to flume tank flow for three 'waterfall' flows (Low, medium, high). Sampling was conducted at six salt marsh sites at four spatial scales: 1 m (the minimal sampling unit) nested within a hierarchy of increasing scales of 1-10 metre (m), 10-100 m and 100-1000 m. Three of the sites were in Morecambe Bay, North West England and three of the sites were in Essex, South East England. The Morecambe Bay samples were taken during the winter and summer of 2013. The Essex samples were taken during the winter, early spring and summer of 2013.

This data was collected as part of Coastal Biodiversity and Ecosystem Service Sustainability (CBESS): NE/J015644/1. The project was funded with support from the Biodiversity and Ecosystem Service Sustainability (BESS) programme. BESS is a six-year programme (2011-2017) funded by the UK Natural Environment Research Council (NERC) and the Biotechnology and Biological Sciences Research Council (BBSRC) as part of the UK's Living with Environmental Change (LWEC) programme. 
description: Sediment cores (16 centimetre (cm) diameter, 30 cm height) including above ground vegetation were collected in each 1 x 1 m quadrat. Each core was placed horizontally in the 'waterfall force' of the re-circulation flume for 1.5 hours (0.5 hour at low force, 0.5 hour at medium force, 0.5 at high force). Sediment erosion rate was calculated from the amount of mass lost over half an hour with measurements taken time = 0 minutes (mins), 5 mins, 10mins, 15mins and 30mins. Results were recorded onto field sheets. These data were transferred into an Excel file and calculations carried out. Results were exported as comma separated value files for ingestion into the EIDC.  The location of the sample sites was determined by randomly allocated quadrats. Each site consisted of a rectangular area of saltmarsh between 400 x 500 m to 1000 x 1000 m in size, dependent upon saltmarsh length (parallel to shore) and width (perpendicular to shore), including part of the low, mid and high marsh zones. Twenty-two 1 x 1 m quadrats were randomly allocated to each site rectangle using R (R Development Core Team, 2014) to specify four different spatial scales (A = 1 quadrat only, B = 3 quadrats at 1 m to 10 m apart, C = 6 quadrats at 10 m to 100 m apart, D = 12 quadrats at 100 m to 1000 m or site maximum).

title: Averaged WRF (Weather Research and Forecasting) data for the Rio Santa and Vilcanota regions, Peru, 1980-2018

description: Averaged outputs from the WRF (Weather Research and Forecasting) model for the Rio Santa and Vilcanota, Urubamba and Vilcabamba catchments in Peru. Averaging was applied over the entire model period from 1980 to 2018.

Data includes:
- Averaged precipitation and air temperature records and the related standard deviation at a 4km resolution (annually and for each season) for each catchment.
Monthly averaged and monthly totals of air temperature and precipitation (averaged over each catchment).
- WRF model input elevation for each catchment.
- WRF total precipitation and maximum/minimum air temperature at the location of five on-glacier weather stations (Artesonraju Glacier, Shallap Glacier, Cuchillacocha Glacier, Quisoquipina Glacier and Quelccaya Ice Cap) at a daily resolution from 1980 to 2018. 
description: The Weather Research and Forecasting (WRF) model version 3.8.1 was run from 1980 to 2018 over an outer domain with 12 km horizontal resolution covering Peru, and two inner domains with 4 km horizontal resolution covering the two study catchments (the Rio Santa and Vilcanota catchments). 
The precipitation and temperature data were bias-corrected against in-situ precipitation and air temperature observations in both regions. 
For the bias correction, the model precipitation output is first corrected for the number of wet days, then a constant multiplicative correction is applied to adjust the magnitude. Furthermore, the model minimum and maximum daily temperatures are corrected additively, with the correction amount constant across the domain for the maximum daily temperature, and variable with latitude, longitude and height for minimum daily temperature.

title: Individual effects of mechanical and chemical control treatment on Ligustrum lucidum and other exotic species invading subtropical forests, Horco Molle, Tucumán, Argentina, 2021-2023

description: The data resource consists of invasive tree species individual responses to mechanical-chemical/chemical treatments on plots established on invaded sub-tropical mountain secondary forests (Yungas). Those plots are in the Horco Molle experimental reserve and Parque Sierra de San Javier (Horco Molle), Tucumán, Argentina. The current database belongs to an experiment that we conducted to investigate management control of the invasion of non-native species Ligustrum and other exotic species to restore native tree diversity from June 2020 to November 2023. 

The work was carried out as part of NERC grant NE/S011641/1 Optimising the long-term management of invasive species affecting biodiversity and the rural economy using adaptive management.

description: The data looks at invasive tree species individual responses to mechanical-chemical/chemical treatments were part of a field experiment on the management of secondary forests affected by Ligustrum lucidum invasion. This was undertaken by establishing 6 permanent plots of 240 metres by 140 meters each (3.36 hectares, see included shapefile). Plots were established in pairs (3 pairs in total), where one element of the pair was assigned as the null scenario (no actions applied), and the other was the control (L. lucidum control and native tree planting). Before management actions, we conducted the census.

The data includes the responses of 1184 stems of invasive trees (mainly Ligustrum lucidum) located in 3 plots under management with arbitrary coordinates (x for the longest side and y for the shortest) to assess the location of each tree. For each tree stem with a perimeter at breast height (PBH) >15.7 cm, the tree was assigned a tagged ID and the species was recorded, the PBH measured and the presence of secondary stems. At a later stage, a treatment was assigned (mechanical-chemical or only chemical), taking into account PBH sizes and locations (to have similar quantities of treatment along individual sizes and locations). 

For the stems assigned to a “mechanical-chemical treatment", we cut the stem with a chainsaw and immediately applied the herbicide aminopyralid (1.5% water-dissolved solution). For the stems assigned to a “chemical treatment", we injected the same herbicide into the stem. Every month, we monitored the individual responses to treated stems (resprout, stress signs, death). 

After one year from the control, we applied a second treatment to the stems with mechanical-chemical treatment that had been resprouted. The stems with only chemical treatment had no effect, and the cost of application was high, so we did not apply a second treatment. The individual responses for all the mechanical- chemical-treated stems every two months for one year. 

Data were recorded onto field sheets, transferred into spreadsheets and exported as comma-separated value (CSV) files for deposit into the EIDC.

title: Hourly data from automatic water monitoring buoy from Blelham Tarn, 2016 to 2018 

description: This dataset consists of hourly lake temperature, air temperature, solar irradiance and wind speed data from an automatic water monitoring buoy on Blelham Tarn, a lake in the North West of England. The lake temperatures are measured at 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 and 12 m depth (see supporting documentation for more information). Measurements were taken every four minutes and calculated as hourly averages.  All data is given in GMT (Greenwich Mean Time). The data were collected by the UK Centre for Ecology & Hydrology.

This work was supported by the Natural Environment Research Council award number NE/R016429/1 as part of the UK-SCAPE programme delivering National Capability.
description: The instruments measure data every four minutes, the hourly averages provided in this dataset are calculated by an Oracle database. The average is calculated over the previous hour, e.g. the value for 2 p.m. is the average of the data between 1 and 2 p.m., excluding the data measured at 1 p.m., including the data measured at 2 p.m. 

Data has been checked visually and any obvious errors introduced by hardware malfunctioning have been removed. Any data gaps are due to buoy maintenance work or sensor / logger problems.

title: Cultural ecosystem services provided by cockles in Portugal, Spain, France, Ireland and the UK, 2018-2020

description: Data comprise scores (from 0 to 5) of examples of cultural ecosystem services provided by cockles from Portugal, Spain, France, Ireland and the UK. All data were collected using an a priori framework to classify evidenced examples of services during a face-to-face workshop held in Vigo in north-west Spain, 10th April 2018, with 28 participants from eleven organisations. The workshop was followed up over the following months by smaller country-specific meetings, mostly held by teleconference call or video call and by email. 

The data were collected as part of a research and industry collaboration, under the COCKLES project ‘Co-operation for restoring cockle shellfisheries and its ecosystem services in the Atlantic Area’, co-funded through the European Regional Development Fund (ERDF).


description: The data were collected through a face-to-face workshop, and a series of virtual meetings and follow-up activities with small in-country teams of experts and stakeholders.

title: Nitrous oxide and methane fluxes from different understory treatments in oil palm plantations in Riau, Indonesia 2018-2019

description: This dataset contains terrestrial fluxes of nitrous oxide (N2O), methane (CH4) and ecosystem respiration (carbon dioxide (CO2)) calculated from static chamber measurements in mature oil palm plantations on mineral soil, managed by Sinar Mas Agro Resources and Technology Research Institute (SMARTRI) and located on the Ujung Tanjung Estate in Riau, Sumatra, Indonesia.  Measurements were made monthly, from October 2018 until September 2019.

A total of 54 static chambers were installed across nine plots, representing three different understory vegetation treatments: normal complexity (an intermediate-level of understory spraying with herbicide); reduced complexity (spraying of all understory vegetation with herbicides); and enhanced complexity (no herbicide spraying and limited understory cutting). Six chambers were installed in each of the nine plots, resulting in 18 replicates of each treatment. In addition, soil moisture measurements were also taken around each chamber.

The dataset was associated with a foreign research permit, issued by Foreign Research Permit Division Ministry of Research and Technology/National Research and Innovation Agency, Indonesia. As the project spanned two years it was covered by two permits, RISTEK permit number: 323/SIP/FRP/E5/Dit.KI/X/2018 and RISTEK permit number: 8B/TKPIPA/E5/Dit.KI/VIII/2019.
description: The data were collected using the static chamber method. Gas samples were taken from chambers in the field via syringe and injected into vials for storage and later analysis. Samples were analysed on a gas chromatograph (GC) in the laboratory. Concentrations were calculated from GC peak areas, calibrated against standard gases of known concentration. Fluxes were calculated from the concentration change in each chamber by linear and non-linear regression, using the R package RCflux. Fluxes are expressed as micromoles of methane per square metre per second. Each flux has an associated 95 % confidence interval, based on the regression fit, which gives a guide to the reliability and uncertainty of each measurement.

This work is part of the Biodiversity and Ecosystem Function in Tropical Agriculture (BEFTA) programme, a collaborative research project established in 2012 as a collaboration of the University of Cambridge and Sinar Mas Agro Resources and Technology Research Institute (SMARTRI). This work was funded by the UK Natural Environment Research Council (grant NE/R005214/1).
