title: Chemical contaminants and shell index values for gannet eggs

description: This dataset gives concentrations of chemical contaminants in the contents of eggs collected from colonies of the northern gannet, Morus bassanus, in the United Kingdom. The majority of eggs analysed are from colonies on Ailsa Craig (Firth of Clyde) and Bass Rock (Firth of Forth) and have been collected since 1971. The study examined 658 eggs collected between 1971 and 2009. Eggs analysed by the PBMS are collected by licensed collectors. Contaminants measured include organochlorine pesticides, total mercury, total PCBs and, for recent years, individual PCB congeners. The PBMS is a long-term, national monitoring scheme that quantifies the concentrations of contaminants in the livers and eggs of selected species of predatory and fish-eating birds in Britain. Levels of contaminants are monitored to determine variations between species and regions, changes over time and effects on individual birds and their populations. The Scheme is funded by CEH, Natural England, the Environment Agency (EA) and the Campaign for Responsible Rodenticide Use (CRRU).
description: Fresh eggs are collected by licenced egg collectors and are sent to the Predatory Bird Monitoring Scheme (PBMS) at CEH Lancaster. The contents of the eggs are sampled and are 1) sent for analysis by the CEH Analytical facility and 2) retained for archive purposes. The biometric data (whole egg weight, length and breadth, etc) are entered by technician onto a MSAccess form which uploads directly to an Oracle database (managed internally by Computer Support). Chemistry batch files containing concentrations of pesticides in tissues are loaded directly into an Oracle database.

title: Local population density of woodland birds from a manipulation experiment in Wytham Woods, Oxfordshire, UK 2021

description: This dataset contains information about local population densities of great tits, blue tits, marsh tits and nuthatches from a manipulation experiment. The time, location and bird species were recorded using a Passive Integrated Transponder (PIT) tag attached to each bird and the information recorded using a Radio Frequency Identification (RFID) antenna within the feeder. Population density was manipulated by programming automated feeders to only open for a specific set of individuals (creating low- and high-density treatments). Local population densities were recorded using automated bird feeders at six experimental and two control sites prior to and during the manipulation. The experiment took place in Wytham Woods, Oxfordshire, UK between January and March 2021, as part of a study on the effects of ecological factors on social structure and information transmission. The work was supported by the Natural Environment Research Council (Grant NE/S010335/1, The ecology of behavioural contagion in natural systems.)
description: Automated bird feeders were used to collect the described data. Each of the feeders had one access hole with a clear flap and an inbuilt Radio Frequency Identification (RFID) antenna within the perch. All birds equipped with a Passive Integrated Transponder (PIT) tag that landed on the perch got recorded, and the time and date of visits stored on a Secure Digital (SD) card. The flap can be programmed to open only for specified PIT tagged individuals. This allowed us to manipulate local densities by specifically restricting access to each feeder. Feeders were visited every two to three days, to refill food, check feeder performance and collect data. For the final dataset, erroneous recordings (e.g. entries with a wrong date or tag number) were removed. Data are provided as comma separated value files for deposit into the EIDC.

title: Reservoir inflows and release data, and optimised monthly rule curve ordinates (upper, lower and critical) for Pong and Bhakra reservoirs in Northern India

description: Data comprise reservoir inflows and release data (including spills), evaporation loss and optimised monthly rule curve ordinates (upper, lower and critical) for Pong and Bhakra reservoirs in Northern India. Also included in the rule curve data are associated reservoir rationing ratios that can be applied to  gross demand when rationing is also indicated. 

Data contain monthly Inflows, net-evaporation loss and release (all in million cubic metres, i.e. x 10^6 m^3) as simulated by WEAP for the Pong and Bhakra reservoir for the baseline (1989 - 2008); mid-century (2032-2050) and end-century (2082-2100) periods. The future inflows were based on forcing the WEAP model of the basin with climate projections of the GFDL-CM3 CMIP model

The data were collected by Heriot-Watt University under the Sustaining Himalayan Water Resources in a Changing Climate (SusHi-Wat) project funded by NERC.
description: ReservoirData.csv. Data contain monthly Inflows, net-evaporation loss and release (x 10^6 m^3) as simulated by WEAP for the Pong and Bhakra reservoir for the baseline (1989 - 2008); mid century (2032-2050) and end-century (2082-2100) periods. The future inflows were based on forcing the WEAP model of the basin with climate projections of the GFDL-CM3 CMIP model.
Units - million cubic metres, i.e. x 10^6 m^3
RuleCurve.csv. Data contain optimised rule curves ordinates or storage levels (x 10^6 m^3) for the Pong and Bhakra reservoirs:
1.	Smax (x 10^6m^3) Maximum storage level (= reservoir capacity)
2.	URC (x 10^6m^3) Upper Rule Curve (URC) target storage levels (January - December);
3.	CRC  (x 10^6m^3) Critical Rule Curve (CRC that triggers water rationing) storage levels (January - December).
4.	LRC (x 10^6m^3) Lower Rule Curve (LRC) target storage levels (January - December);

title: Taxonomy for macroinvertebrates in Welsh upland rivers (2012-2013)

description: These data are for macroinvertebrate taxonomy and abundance of Welsh upland rivers. The sampling sites were located in small and medium catchments across Wales. Sampling took place in either spring 2013 for sites in the Wye catchment or during 2012 for the other catchments. At each sampling point, 2-minute kick-samples were taken from river riffles to represent macroinvertebrate composition. Samples were preserved in industrial methylated spirit on site. Samples were then sorted and identified in the laboratory.

The main goal of this survey was to characterise a gradient of aquatic biodiversity associated with different environmental settings for example land-use intensify and recovery from acidification. 

Dr Isabelle Durance was the responsible of organising the surveys, Dr Hugh Feeley was in charge of collecting, processing and sorting the invertebrate samples. Kath Layer was commissioned by Cardiff University for the identification. The work was carried out under Diversity in Upland Rivers for Ecosystem Service Sustainability (DURESS) project (Grant reference NERC NE/J014818/1). DURESS was a project funded by the Natural Environment Research Council (NERC) Biodiversity and Ecosystem Service Sustainability (BESS) programme.
description: Invertebrates were collected by standardised kick sampling methods. Samples were preserved on-site by adding 100 per cent industrial methylated spirit (IMS) to the sample volume. In the laboratory, samples were hand sorted, preserved in 70 per cent IMS. Major groups were identified and counted to species or genus for most taxa or to family in cases where taxonomy was difficult or larvae were insufficiently well developed.

Results were entered into an Excel spreadsheet. Data was exported as a comma separated value file for ingestion into the Environmental Information Data Centre (EIDC)

title: Manual water table measurements from experimental microcatchments in peatlands at Stalybridge, Peak District, UK, 2019-2022

description: This dataset contains depth to water table measurements from ten experimental microcatchments (0.4-3.9 hectares) on Stalybridge Moor, an upland peatland in the Peak District, UK. The data extend from 2019 to 2022, covering a period before and after gully blocking took place in six microcatchments, with four microcatchment kept as a non-restored control. Monthly measurements from October-February, summer/autumn.
description: Depth to the water table from the peat surface was measured using a blow tube in PVC dipwells which were installed in the peat surface. The height of the dipwell protrusion from the peat surface is also measured and then subtracted from the recorded depth of the blow tube to get the depth of water table from the peat surface. Within each microcatchment, there were two dipwell clusters, one near the gully edge and one far from the gully edge. Each cluster contained five individual dipwells. Each cluster had a peat anchor installed, a metal rod inserted down to the mineral layer, to serve as a vertical datum to monitor potential changes in dipwell protrusion height (E.g. accidental or intentional human interference with installed equipment).

title: Tree and shrub vegetation surveys in Monks Wood National Nature Reserve, Cambridgeshire, England, 2005-2006

description: Vegetation surveys from 35 transects in 2005 and 34 transects in 2006, focusing on tree and shrub abundance and sizes, in Monks Wood National Nature Reserve (Cambridgeshire, England). The transects were located in occupied territories of Marsh Tits, and also unoccupied areas of the wood used as controls, in order to sample the birds' habitat. However, the surveys also provide representative and widespread sampling of the overall woodland. The surveys include all woody tree and shrub species, and also standing and fallen deadwood, in different size categories. Fieldwork was undertaken and supervised by the authors and funded by the Natural Environment Research Council's National Capability investment.
description: Data were collected in the field on recording sheets, entered into an Excel spreadsheet and checked for quality control. Data were exported as comma separated value (.csv) files and deposited with the EIDC.

title: Stable isotope and community abundance data from freshwater macroinvertebrates collected during a mesocosm-based drought experiment

description: The dataset contains stable isotope concentration (d13C and d15N) and community abundance data for a range of aquatic macroinvertebrate taxa measured during a mesocosm drought experiment. The aquatic macroinvertebrates were sampled from four mesocosm system blocks at the Llyn Brianne Experimental Observatory. There were three experimental treatments included within each block (100% [control], 50%, and 10% of the baseflow discharge). Samples were collected before the treatments, and after 30 days of exposure to the treatments. Taxa were identified down to family level for abundance measurements.

The work was supported by the Natural Environment Research Council (NE/X010597/1), as part of a study to understand ecosystem responses to environmental change through quantifying ecological interactions in freshwater systems.

description: The mesocosm experiment followed a Before-After Control-Impact (BACI) design (Stewart-Oaten & Bence, 2001), and included a 6-month colonisation period (January to July 2023). Discharge treatments were generated by adjusting intake valves on the individual mesocosms, measuring the depth of the water and using pre-existing stage-discharge curves to calculate reductions in flow. Hess samplers (165cm2, 500um mesh gauge) were used to collect macroinvertebrates at each sampling point.

Stable isotope data were generated at UK Centre for Ecology and Hydrology (UKCEH) and reformatted for archiving. Concentrations of d13C and d15N were measured using a Flash EA 1112 Series Elemental Analyzer connected via a Conflo III to a DeltaPlus XP IRMS (Thermo Finnigan, Bremen, Germany).

International reference materials USGS40 and USGS41a (both L-glutamic acid) were used as standards for d13C and d15N and duplicated with each batch of samples. Additionally, the USGS40 was used as a reference material for carbon and nitrogen concentrations.

title: Social data on human wildlife conflict in ten rural communities of Marrupa, Northern Mozambique

description: This dataset includes the transcript of discussion group activities on Human Wildlife conflict, conducted with ten rural communities in Marrupa District, Niassa (Northern Mozambique). It also comprises the results of semi-structured interviews conducted individually in three of the ten selected communities. The ten villages were selected from a forest cover gradient running from villages with a higher forest cover to those within degraded forest areas and consequently low cover. The villages had similar infrastructure, soils, rainfall, and vegetation types. The dataset contains information on the occurrence of conflict with both vertebrate and invertebrate wild species, mitigation strategies, conflict seasonality and trends, but also its impact on agricultural production and livestock rearing. The discussion groups were conducted with six to ten people and the presence of the leader of each village, between May and July 2015. Data were collected as part of a project funded under the Ecosystem Services for Poverty Alleviation (ESPA) programme.
description: Interviews were collected with trained personnel and data collected via individual ODK (Open Data Kit) files on electronic tablets. No amendments were made to the data after collection except for some responses which had text converted to numeric codes for analysis.

title: Model outputs for simulation of soil organic carbon changes on a Red Soil agricultural site in China using integrated Hydrus 1-D hydrology

description: Data comprise soil organic carbon (SOC) content from soil simulations in a small agricultural catchment (Sunjia) which is part of the Critical Zone Observatory (CZO) in southeast China (Jianxi province).

The simulations were performed using the ECOSSE model (a pool-based carbon and nitrogen turnover model) and soil and climate input data were provided by the research farm at the soil science department of the Chinese Academy of Sciences. Simulations were conducted in 2018.
description: The data was collected through model simulations. These were performed to understand the response of soil carbon models to the different methods of simulating hydrology dynamics in soil. The simulations use two different hydrological representations; one a simple piston flow and one the HYDRUS model. The simulations using the HYUDRS (1-D) model read in soil moisture values from files created from simulations of soil moisture using the HYDRUS model. 

Simulations were carried out by Dr Joseph Oyesiku-Blakemore in the Environmental modelling group at the University of Aberdeen. 
The work was part of the UK China Critical Zone Observatory project (the Red Soil project within this group of projects), funded by NERC and NSFC.

title: Blood characteristics of zebra finches following exposure to artificial light at night

description: This dataset contains measurements of four physiological parameters measured in blood samples collected from zebra finches held in indoor cages over a period of 4 months. We measured four parameters: glucose concentration, non-enzymatic anti-oxidant capacity, lipid peroxidation and relative telomere length. Zebra finches were held in groups separated into three different treatments: a control group where birds were held under natural light-dark cycles, a group where birds were exposed to dim artificial light at night during the entire night (FLAN) and a group where birds where partially exposed to artificial light at night, between dusk and midnight (PLAN). Samples were taken at the start, mid-term, and end of the experiment.
description: After collection, one drop of blood was used to measure glucose concentration via a glucose strip test. The remaining blood was kept on ice, immediately brought to a laboratory, where it was centrifuged to separate red blood cells and plasma. These were transferred into two separate tubes and stored at -80 until further analysis.
Plasma samples were used to analyse non-enzymatic anti-oxidant capacity using the Oxy-test and a lipid peroxidation marker, MDA, using mass spectrometry (LC-MS). The red blood cells were used to measure relative telomere length using a real-time RT-qPCR assay.

title: Hydraulic mobility of aquatic insect (Trichoptera) bioconstructions and incorporated sediments

description: Data comprise resistance of aquatic bioconstructions (Trichoptera cases), and the loose sediment they were built from, to hydraulic forces measured in a hydraulic flume.

S1_Velocimetry_data contains the output after post-processing the acoustic Doppler velocimetry data for each flow stage. This includes the mean and SD of velocity (m/s) for each direction (U – downstream, V – vertical and W- cross stream), the quality of the data recorded by the ADV (Signal to noise ratio and correlation) and calculated values of turbulent kinetic energy and bed shear stress. An explanation of each variable and units are included in the file.
S2_Case-grain-size-distribution_data contains the grain size distributions for each caddisfly case obtained by sieving the case sediment. Includes the mass of sediment in half phi size intervals from 0.063 mm to 8 mm diameter. An explanation of each variable and units are included in the file.

S3_Entrainment_data contains the percentage of sediment entrained during each flow stage (1-11). Percentage of sediment measured using photography of sediment remaining on the measurement platform. An explanation of each variable and units are included in the file.

S4_Case-and-entrainment-threshold_data contains the caddisfly case characteristics (mass and a,b&c axes), critical entrainment thresholds and general movement data for each case and loose sediment. An explanation of each variable and units are included in the file.
description: We undertook a hydraulic flume experiment to quantify the effect of caddisfly case construction on sediment transport in rivers. The cases of three species were considered; two that construct different styles of tubular case (Potamophylax latipennis and Sericostoma personatum) and one that builds a domed case (Agapetus fuscipes). We compare the bed shear stress required to transport (1) empty caddisfly cases and (2) individual sediment particles following disaggregation from the case. Cases and sediment were placed in the centre of the flume and hydraulic force increased through 11 flow stages. The amount of sediment eroded at each flow stage was measured using analysis of photographs taken at each stage. Flume experiments were conducted between 20th August and 20th September 2019 and caddisfly collected on 17th June and 18th August 2019.
