title: Eco-physiological responses in oak and hazel, Alice Holt Forest, Hampshire, UK, July 2023

description: This dataset contains information about photosynthesis and gas exchange from tree species in Alice Holt Forest, Hampshire, UK. Data were collected between 18th-20th July 2023, alongside other observations examining the forest canopy structure and photosynthesis. Leaves were sampled across one hazel tree within the understory, and two oak trees. Data from the oak trees were collected with height, using a 12 m tower (six 2 m platforms), with leaves sampled across three platforms. The photosynthesis parameters were collected using a Handy PEA+ continuous excitation chlorophyll fluorimeter and gas exchange data were collected using a LI-COR 6400.

This research was funded by UKRI NERC as part of the SPLICE project (NE/W006596/1).

description: Samples were taken from a tower set up within the forest, between two oak trees, with six platforms at two metre intervals. Each overhanging oak branch was split into leaf clusters, with leaves sampled. The hazel understory was also sampled in the same manner. All labelled leaves were not sampled as some were taken down by the wind between marking and data collection.

Photosynthetic parameters are collected directly from the Handy PEA+ continuous excitation chlorophyll fluorimeter with no processing applied.

Test measurements were taken with the LI-COR 6400 on the 18th, with data collected for leaves across two of the platforms on the 19th and 20th July 2023. Instrument files were copied into .csv files, which were then split per sample.

title: Structure and composition of woodlands across Mozambique

description: This dataset contains quantitative measurements of woodland structure and composition sampled in twenty-seven different villages across three Districts in Mozambique, Africa. Data were collected from 431 plots where tree stem structure and composition, litter and grass biomass, coarse woody debris, and canopy cover data were recorded. Woodlands within seven villages in Mabalane District, Gaza Province, ten villages in Marrupa District, Niassa Province, and ten villages in Gurue District Zambezia Province were sampled. Data were collected in Mabalane between May-Sep 2014, Marrupa between May-Aug 2015, and Gurue between Sep-Dec 2015. This dataset was collected as part of the Ecosystem Services for Poverty Alleviation (ESPA) funded ACES project , which aims to understand how changing land use impacts on ecosystem services and human wellbeing of the rural poor in Mozambique.
description: All data were quality assured by the lead author. When in the field, all teams were trained in data collection methods to ensure consistent robust measurements, and data were continually checked for errors as it was collected. All field teams had a translator to translate from the local language to Portuguese. All data were cleaned post digital entry by checking for extreme outliers in the dataset or unexpected values. Anomalous entries were corrected where possible, or were removed and treated as no record. All observations were recorded in Portuguese, and translated to English by the lead author. All of the data were collected electronically in the field for Marrupa and Gurue survey sites using tablets and ODK software. Wherever possible, pre-set answers or binary responses were used (e.g. has the plot been recently burned: true or false) to systematically record qualitative observations and avoid ambiguous results.

title: Feather isotope ratios and sexing of oystercatchers breeding in Iceland, 2013-2017

description: Dataset comprises  of the delta-13C and delta-15N stable isotopic information from feather samples (for 552 individuals) and the sex (assigned by DNA-analysis of blood samples for 321 individuals) of oystercatchers (Haematopus ostralegus) breeding in Iceland during the summers of 2013-2017. The Icelandic oystercatcher population contains individuals that stay in Iceland year-round and individuals that migrate to mainland Europe in the non-breeding season, and feather isotope ratios provide a means of distinguishing between these migratory behaviours (as confirmed by observations of marked individuals).

These data were collected by a collaborative team from the University of Iceland, University of East Anglia (UK) and the University of Aveiro (Portugal).
description: Feathers were washed in a 2:1 chloroform/methanol solution, left to dry overnight in a fume cupboard and cut into small fragments. Each sample was then weighed and loaded into a combustion Costech elemental analyser coupled to a Thermo Scientific Delta XP continuous flow isotopic ratio mass spectrometer and a Conflo III interface. DNA was extracted from blood samples using a standard ammonium acetate technique (dx.doi.org/10.17504/protocols.io.knycvfw) and diluted to a working concentration of 10–50 ng/μL, and used to assign sex following the methods set out in Fridolfsson & Ellegren (1999: DOI: 10.2307/3677252).

title: Early life asymmetries and the allocation of cooperative care in banded mongooses in Queen Elizabeth National Park, Uganda 2013-2016

description: This is a dataset of the effect of pre-natal provisioning (supply with extra food) on offspring weight and growth, contributions to offspring care, and offspring survival in banded mongooses on the Mweya Peninsula, Queen Elizabeth National Park, Uganda, collected between 2013 and 2016. Pre-natal condition of females was experimentally manipulated by provisioning half of pregnant females in each social group during the second half of pregnancy. The other half of pregnant females did not receive any extra provisioning and acted as matched controls. Through field observations we measured female weight change during pregnancy, weight change during the pup care period following birth (the escorting period), and female contributions to escorting. We also measured pup weight at birth, weight change during the escorting period, and pup survival. Data were collected to examine how extra resources are used by females to level up inequalities in pup weight via the allocation of cooperative care.
description: During manipulated breeding attempts, the pre-natal condition of females was experimentally increased by provisioning half of pregnant females in each social group with 50 g of egg per day for the second half of pregnancy; the other half of pregnant females were not provisioned and acted as matched controls. Across all groups, each manipulated breeding attempt was followed by an non-manipulated breeding attempt in which no females were provisioned. In total we manipulated 34 breeding attempts in 7 social groups, and collected data on 101 provisioned female pregnancies, and 97 non-provisioned female pregnancies. Manipulated breeding attempts produced 50 pups from provisioned females and 50 pups from non-provisioned females. We visited social groups every 1-3 days during pregnancy and after birth to record data on female weight and offspring weight. We performed focals of pups once they had emerged from the den to collect data on escorting (a form of cooperative pup care). During focals we recorded which pups were being escorted, and by which females, to calculate on the amount of escorting that females performed during the escorting period. We recorded similar data on male escorting to compare male and female behaviour. We also collected data on pup survival for the following year after birth.

title: Peatland distribution maps for lowland Peruvian Amazonia, 2022

description: Spatial datasets of predicted land cover, peatland extent, peat thickness and peatland carbon storage for the Lowland Peruvian Amazon. 
description: A total of 1,128 ground reference points of vegetation type, peat presence/absence and (where applicable) peat thickness from the lowland Peruvian Amazon (LPA) were used to train (50% of the data) and validate (the remaining 50% of the data) predictive models of land cover, peatland extent, peat thickness and (in conjunction with laboratory measurements on peat samples) peat carbon storage. Input data to the model included a stack of seven remote-sensing layers, including two Sentinel-2 indices, three ALOS PALSAR-2 bands, SRTM digital elevation data, and a previous land-cover map.

title: Physical and biogeochemical measurements of belowground biomass and carbon content from Scottish salt marshes, 2021

description: The dataset comprises of physical and biogeochemical measurements of belowground (root) biomass from across four Scottish saltmarshes. Sites were chosen to represent contrasting habitats types in Scotland, in particular sediment types, vegetation and sea level history. The data provide a quantitative measure of belowground (root) biomass, organic carbon content and belowground (root) carbon. Samples were collected using a wide gauge gouge corer. The samples were processed to determine belowground (root) biomass, the organic carbon was quantified through elemental analysis and these two data sets were combined to calculate the belowground (root) carbon content. The data were collected to help create a detailed picture of saltmarsh carbon storage in surficial soils across Scotland.

The work was carried out under the NERC programme - Carbon Storage in Intertidal Environment (C-SIDE), NERC grant reference NE/R010846/1
description: Soil cores were taken at each sampling location using a wide diameter gouge corer. The location of the sample was recorded using GPS. Prior to analysis the samples were stored at 4 degrees Celsius at the University of St Andrews. Belowground (root) biomass, organic carbon content and belowground (root) carbon data was produced using standard analytical procedures (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: Vegetation survey of Brachypodium pinnatum herbicide control trials at the Martin Down National Nature Reserve (2012-2015)

description: Vegetation data from botanical field survey of trials of selective herbicide impacts on tor-grass (Brachypodium pinnatum s.l.) control at Martin Down NNR, England.  The data relate to 50 cm × 50 cm quadrats placed in herbicide treated and control plots in a replicated experiment, including a baseline (pre-treatment) survey in 2012 and three surveys after repeat treatments in 2013, 2014 and 2015.  Data include percentage cover of plant species, bare ground and plant groups (total grasses, total forbs) as well as data on plant indictor status and Ellenberg N value. The data cover areas of both sparse B .pinnatum cover, with the goal of preventing B. pinnatum from increasing to dominance, and dense B .pinnatum cover, with the goal of reducing B. pinnatum cover to a level which allowed the reestablishment of other calcareous grassland species.  Data have been used to analyse herbicide impacts on the cover of target species B. pinnatum and non-target species groups (other grasses, forbs, positive indicators, negative indicators, arable indicators), as well as community level analyses (Ellenberg-N weighted cover, DCA). 
description: Trial plots were established at Martin Down (50.975 N, 1.937 W) in summer 2012 on calcareous grassland containing two levels of B. pinnatum cover - ‘dense’ and ‘sparse’. For each level, three experimental blocks were marked out, each consisting of seven plots (each plot =3 m wide x 10 m long).  Within each block, each plot was assigned a different herbicide or management application at random. 

Five selective (Propaquizafop, Tepraloxydim, Fluazifop-P-butyl, Cycloxydim, Propyzamide) and one broad-spectrum herbicide (glyphosate) were selected on the basis of their efficacy for controlling perennial grasses in agricultural and/or forestry applications.  All herbicides were applied evenly across the entire plot.The control experimental management in both sparse and dense areas was a single annual cut in late summer (July-August) with a mechanical mower which removed cut material. 

Vegetation monitoring took place in July-September of 2012 (before all herbicide applications to provide a baseline), 2013, 2014 and 2015.  Within each plot, vegetation surveys were conducted by placing five 50 cm × 50 cm quadrats at approximately 2 m intervals (i.e. vertices of a “W”-shaped transect through the plot).  Quadrats avoided the outermost 50 cm of each plot, where there was an increased potential for spray drift from neighbouring plots.  Within each quadrat, the percentage cover of B. pinnatum, all vascular plants and bare ground were recorded.  In the first, third and fourth quadrat, all plants were recorded to species level, whilst in the second and fifth quadrat percentage cover was recorded per group level only (grasses and forbs), as a result of limited time and funding for survey. For further details please see the supporting documentation.

title: Earthworm toxicity data for exposure to cerium oxide nanoparticles

description: This dataset was generated from a laboratory experiment investigating the toxicity of Cerium oxide nanoparticles and non-nanoparticles to the earthworm Eisenia fetida. The toxicity test procedure followed the OECD guideline 222 (earthworm reproduction test (Eisenia fetida/andrei)). Exposure concentrations for both nano and non-nano Cerium oxide particulate forms and the cerium salt materials were 41, 102, 256, 640, 1600, 4000, 10000 mg Ce per kg (Dry Weight soil). Each replicate container held 500 g soil with ten worms. There were three replicate containers per treatment concentration. All exposures were run concurrently and hence effect could be benchmarked against a universal control treatment for the experiment. This comprised of ten separate replicates of Lufa 2.2 soil without amendment of any form of Cerium.

title: Motion-activated camera trap images from the ECN Cairngorm long-term monitoring site, 2010-2022

description: Motion activated camera traps were installed in pine woodland and regenerating heathland from 2010 as part of UK Environmental Change Network long-term monitoring in the Allt a'Mharcaidh catchment, Cairngorms National Park, Scotland.  

The image catalogue contains 8050 wildlife images identified to species or group where possible.  This forms part of the accompanying dataset which includes information on over 66,000 classified images, recording the presence of blank (empty) images, wildlife, people, dogs and mountain bikes.  Furthermore it includes group identification where a series of images occur within five minutes of each other.

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: Data was collected and processed using a standardised methodology included as a supplementary file. 

Images were collated directly from cameras into yearly named folders by year.  Yearly collections were then processed through Microsoft’s object detection AI, MegaDetector (https://github.com/microsoft/CameraTraps/blob/main/megadetector.md), to streamline image content identification.  Data extraction then took place using content filters within 'Timelapse: An Image Analyser for Camera Traps' software (https://saul.cpsc.ucalgary.ca/timelapse) with output data exported as a .csv file.

Any errors with time and date extracted from image EXIF, were corrected manually during the final processing step.  The data was manually checked for errors but has not been through an exhaustive QC process which is recommended as good practice prior to use.

title: Wild rodent trapping, tracking and sampling for genetics and gut microbiome, Silwood Park, Berkshire, November 2014 to November 2015

description: This data set is a combination of trapping data, tracking data and data on the genetic relatedness and gut microbiome composition of wild rodents caught in 2.3 ha study site in Nash’s Copse, Silwood Park, from November 2014 to November 2015. As part of a longer-term capture-mark-recapture study, three species of rodents were trapped with Sherman live-traps fortnightly for 12 months: wood mouse (Apodemus sylvaticus), yellow-necked mouse (Apodemus flavicollis) and bank vole (Myodes glaerolus). Upon capture, they were measured, weighted, sexed, aged and a tissue sample and a faecal sample were collected from all mouse individuals for genetic and microbiome analyses. All rodents were released to their location of capture. First time each individual was captured, they were injected with a permanent subcutaneous identification  Radio-Frequency Identification(RFID)-tag (Passive Integrated Transponde-tag). The tagged rodents were subsequently tracked with a set of custom-made tracking devices (loggers). Loggers produced dense time-stamped occurrence data suitable for inferring spatio-temporal activity patterns of rodents, such as temporal niches, home ranges and social networks. Tissue samples were used to genotype the wood mouse population and bacterial DNA extracted from faecal samples were used to profile their gut microbiome composition.

This work was funded by a NERC independent Research Fellowship to Sarah Knowles (NE/L011867/1)
description: Wild rodents were trapped fortnightly, tagged and continuously monitored with tracking technology for one year.  This is a natural rodent population and no experimental manipulations were made. Upon capture, faecal samples were collected from the rodents and a piece of ear tissue was collected upon first capture of each individual. Tissue samples were stored in ethanol in -20 C and faecal samples were stored without buffer in -80 C for 3 years. In 2017 DNA was extracted from the faecal samples of wood mice and their gut microbiome was characterised from this by amplification and sequencing of the V3 region of bacterial 16S rRNA marker gene. In 2018 the wood mouse population was genotyped and their pedigree reconstructed from ear tissue samples using 11 microsatellite markers. Details of the data and the cleaning process can be found from the supporting documentation.

title: Policy interviews on trypanosomiasis in Zambia, 2013

description: This resource contains anonymised policy interviews on trypanosomiasis in Zambia from 2013 conducted by Catherine Grant (Institute of Development Studies) and Noreen Machila (University of Zambia, Department of Disease Control). These interviews explore the differing opinions of various stakeholders in relation to trypanosomiasis, a widespread and potentially fatal disease spread by tsetse flies which affects both humans and animals. It is an important time to examine this issue as human population growth and other factors have led to migration into new areas which are populated by tsetse flies and this may affect disease levels. This means that there is a greater risk to people and their livestock. Opinions on the best way to manage the disease are deeply divided (Source: Author Summary- Grant, C, Anderson, N and Machila, N [Accepted] Stakeholder narratives on trypanosomiasis, their effect on policy and the scope for One Health, Public Library of Science Neglected Tropical Diseases (PLOS NTD).

This was part of a wider research project, the Dynamic Drivers of Disease in Africa Consortium (DDDAC) and these interviews contributed to this consortium.
The research was funded by NERC project no NE/J001570/1 with support from the Ecosystem Services for Poverty Alleviation Programme (ESPA).
description: Stakeholders were selected to represent a broad range of perspectives. The choice of stakeholders was based on a literature review of trypanosomiasis policy and its history in Zambia alongside an internet search using key words. Stakeholders identified were then categorised under a number of headings. These people were contacted for face to face interviews, or if this was not possible they were interviewed over the phone. Verbal consent was obtained prior to commencing all interviews. The resulting transcripts entered into Microsoft Word and coded manually to enable us to analyse the data and pick out narratives within the content. The transcripts were stored at the Institute of Development Studies and the University of Zambia as Word documents. To meet the requirements of the Environmental Information Data Centre the Microsoft Word document was anonymised and converted into Rich Text Format (rtf).

title: Areas affected by landslides following Typhoon Mangkhut in Itogon, Philippines, September 2018

description: This dataset contains the areas affected by landslides triggered by Typhoon Mangkhut in the area of Itogon (Benguet, Philippines) between the 13th and 15th of September 2018. The polygons were mapped using very high-resolution satellite imagery from before and after the typhoon. The pre-typhoon images were captured on 18/02/2018 and the post-typhoon images were captured on 02/03/2019 using the World-View 2 satellite. Google Earth imagery was also used as a supplementary source. The study area covers 570 km2.
description: The polygons of the landslides were mapped by a member of team. The technique to map them was visual observation of evidences of change before and after the typhoon, that would correspond to the appearance of a landslide. The inventory was checked by a different person afterwards.
