title: Eddy covariance measurements of carbon dioxide, energy and water fluxes at a winter wheat field, Lincolnshire, UK, 2012

description: This dataset contains time series observations of surface-atmosphere exchanges of net ecosystem carbon dioxide exchange (NEE), sensible heat (H) and latent heat (LE), and momentum (τ) measured at a field of winter wheat in Lincolnshire, UK during the 2012 growing season. 

Turbulent flux densities were monitored using the micrometeorological eddy covariance (EC) technique between 5th April 2012 and 8th August 2012. The dataset includes ancillary weather and soil physics observations, as well as variables describing atmospheric turbulence and the quality of the turbulent flux observations.
description: Turbulent flux densities were calculated from the raw EC data using the EddyPRO® Flux Calculation Software Version 6.1.

Quality Control of EC data involved removal of statistical outliers and tests that theoretical requirements for the successful application of the EC technique were not violated significantly. 

Data gaps in EC data (NEE, LE, H) and the partitioning of NEE into gross ecosystem production and total ecosystem production were performed using the REddyProc Package for R (Reichstein et al., 2019).

Further details are available in the supporting documentation.

title: Soil moisture, temperature and bulk density and earthworm abundance and biomass along transects from hedges into arable fields, pasture fields, ley strips established in arable fields and arable strips established in pasture fields at a farm in West Yorkshire, England (2015-2017)

description: Data are presented on earthworm abundance with distance from hedgerows was recorded for arable fields and pasture leys at Spens farm, the University of Leeds experiment farms, Yorkshire. Sampling was carried out annual from April 2015 to April 2017 with additional sampling in December 2015, and July and October 2016. Pits were excavated and soil hand sorted for earthworms. Mustard solution was then poured into the pit and any emerging earthworms collected. All earthworms were preserved in ethanol for identification using the Sims and Gerard Field studies key. At each pit the following measurements were also taken: soil moisture, soil temperature, soil bulk density. The samples were taken to determine the influence of leys on soil quality by Miranda Prendergast-Miller and colleagues as part of the SoilBioHedge project (Grant Reference NE/M017095/1) funded by the NERC Soil Security Programme. (Grant Reference NE/M017044/1).
description: Soil pits (18 x 18 x 15 cm) were excavated along transects and the soil hand sorted for earthworms. Mustard solution was then poured into the pit and any emerging earthworms collected.  All earthworms were preserved in ethanol for identification using the Sims and Gerard Field studies key. At each pit the following measurements were also taken: three soil moisture readings in millivolts (mV) were taken at both 5 and 10 cm depth using a ML3 ThetaProbe Soil Moisture Sensor, (Delta-T Devices); single soil temperature measurements at 5 and 10 cm depth using a Checktemp®1 probe (Hanna Instruments); soil bulk density samples were taken at 5 and 15 cm soil depth using steel bulk density rings (118 cm3), soil density was calculated on an oven dry basis. The data were entered into Excel spreadsheets and exported as comma separated value files (csv) for ingestion into the Environmental Information Data Centre.

title: Assortative mating in Drosophila simulans and Drosophilia sechellia females

description: The dataset presents data on female mate choice totals for different species pair combinations. Data are presented for wild types and inbred lines of  Drosophila simulans and Drosophilia sechellia females. Most of the data was generated in a laboratory at Stony Brook University, with some at Oxford University. Each test was conducted in 28.5 x 95mm plastic vials.

Data was collected at different points between 2014 and 2021 by the lead data author.

The work was conducted on mate choice preferences to determine how preferences vary between strains, species and among hybrids.

Work was funded under NERC grant NERC NE/S010351/1. Investigating the dual role of mate choice genes in behavioural isolation and hybridization.

description: Three tester female were given the choice between D.  sechellia  and D. simulans males. Courting flies were watched for four hours. Once the first pair mated, the vial was moved to -20C until the copulating pair was frozen. The male species was determined by examining the male genitalia, which is distinct for  D.  sechellia  and D. simulans males.

title: Mark-recapture data of individual birds from ringing records, Glasgow, UK, 2014-2022

description: This dataset contains information on individual birds caught at nestboxes or via mistnetting at 20 sites along a 35 km urban gradient in Glasgow, Scotland, 2014-2022. For each capture, we recorded the ring number of the individual, morphological parameters, whether samples were obtained and the sample number (blood, feather, faeces). The morphological measurements obtained were: Wing length (total length of the stretched wing, as per BTO guidelines), Weight (to the nearest 0.01 g), Tarsus length (using a caliper with 0.1 cm precision).

Data were collected to investigate the effects of urbanisation on daily activity patterns, reproductive traits and population dynamics of passerine birds.
description: We monitored an approximately 35 kilometre urban-non-urban gradient, with the extremes of the gradient being Glasgow city centre and Loch Lomond National Park, Scotland. This gradient has been monitored annually between 2014 and 2022 and has consisted of between five and twenty sites, depending on the year. 

Blue and great tit nestbox populations were monitored annually from 1st April until 20th June between 2014 and 2022. Productivity was monitored through recording breeding attempts in nestboxes. 

From the 1st April, nestboxes were monitored weekly until incubation commenced. The date the first egg was laid and clutch size were recorded. Once incubation was observed to have begun, nestboxes were not checked again until fourteen days after incubation commenced to minimise disturbance. After this point, nestboxes were checked every other day until chicks were observed. Once chicks were observed, between two days and ten days after hatching, an attempt was made to catch the breeding adults on the nest. The adult birds were marked with a unique metal ring, or their ring number noted if they had been ringed in a previous year. Thirteen days after hatching, nests were visited again to individually mark each of the nestlings within the broods using a unique metal ring. 
Opportunistic mist netting was also undertaken outside of the breeding season at both study sites. This supplements the mark-recapture data from catching adults and ringing nestlings at the nestboxes, and also contain data on other passerine species bycatch. The morphological measurements obtained were: Wing length (total length of the stretched wing, as per BTO guidelines), Weight (to the nearest 0.01 g), Tarsus length (using a caliper with 0.1 cm precision).

At the end of every year data collected during that year is checked and uploaded on a central long-term Access database that enables linking between reproductive attempts and individual bird information (mark-recapture data), both of which are deposited with the EIDC.

title: Triazine, organophosphate and pyrethroid (TOP) pesticide data from rivers [LOIS]

description: Triazine, organophosphate and pyrethroid (TOP) pesticide data from river water collected at various sites within the Humber catchment area as part of the Land Ocean Interaction Study project (LOIS).. Water samples were collected weekly and during storm periods between 1994 and 1996. The unfiltered samples were extracted on the day of collection using solid-phase-extraction (SPE), the SPE cartridges stored overnight at 4 degreesC and then transported to the Institute of Freshwater Ecology (IFE), Wareham for elution, drying and Gas Chromatography (GC) analysis. Pesticides measured were Atrazine, Cyanazin, Desmetryn, Fenitrothion, HCH gamma, Malathion, Parathion, Permethrin, Prometryn, Simazine, Terbutryn. The sampling and extraction of the pesticides was carried out by the LOIS team at York University and the elution and sample preparation for GC analysis was done at IFE.
description: Samples were collected in presolvent washed 1 litre borosilicate bottles from the midpoint in the channel by immersion. The samples were returned to the LOIS York Laboratory for separation by passage through frits (Isolute 120-1008F) and spe columns (1 g C18, Isolute 221-0100-C) according to SOP 17/14.11.93 (IFE, Wareham). The samples were stored overnight at 5 C and transported to IFE, Wareham for elution using ethylacetate (EtAc) with the eluate from the filtered solids and water combined following SOP 24/20.4.94 (IFE, Wareham). Extracts were dried and concentrated using nitrogen. Triazines and Organophosphorus pesticides were analysed using nitrogen-phosphate bead detector (Perkin Elmer) and the Pyrethroids by GC/MS in single ion mode (Hewlett-Packard). Blank water samples (ultrapure water) were taken into the field during sample collection and opened and closed on site and then analysed in the same way as the other samples. Spiked water samples containing all the pecticides were included in each batch to enable checks on the pesticide recoveries. Internal standards were included in the GC analysis: ametryn for GC/NPD and Decachlorbiphenol for GC/MS. Triazines and organochlorine compounds were identified by their relative retention time (RRT) with respect to ametryn (+/- 0.002 RRT) and on some samples these were verified by concentration of the samples and GC/MS. Their RRT and coincidence of the base ion and one other ion fragment identified the pyrethroids. A zip file of box-and-whisker plots for each determinand is available, showing the range of values (median, inter-quartile range, 1.5 * inter-quartile range, outliers) recorded at each site to enable prospective users to understand data quality.

title: Vascular plant and bryophyte survey from a 33-year chronosequence on bare chalk, Dorset, 2019-2020

description: Vascular plant and bryophyte survey data from a 33-year chronosequence on bare chalk, used to investigate primary succession. The bare chalk plots were created from archaeological excavations on Down Farm, north Dorset, between the years 1986 and 2018, resulting in 13 different plots. The vascular plant survey was carried out in July 2019 using 50 cm x 50 cm quadrats. Quadrats were recorded every 1 m along a 16 m transect in each of the 13 plots. The bryophyte survey was carried out in February 2020 using 20 cm x 20 cm quadrats, along the same transects for 11 of the 13 plots. 
description: A total of 13 transects (16 m in length) were set up in July 2019, with one in each of the excavated blocks dated 1986, 2004–2008, and 2013–2018 (2 blocks were excavated in 2016). The percentage cover of vascular plant species were recorded in 50 cm x 50 cm quadrats every 1 m along each of the 13 transects, giving a total of 208 quadrats. Vascular plants were identified to species level, with the exception of Taraxacum microspecies. The percentage cover of bryophytes were recorded in February 2020 using the same methodology, but with a 20 cm x 20 cm quadrat. Two plots were not recorded for bryophytes, the first of which (excavated in 2006) was due to rubble left on the plot, which would have influenced the colonisation of bryophytes and the second plot (excavated in 2016) was excluded due to time constraints, as there was already another plot recorded of this age. Bryophytes were identified to species level, with the exception of a few small and/or infertile individuals, where it was only possible to classify specimens to a group level (affecting some Didymodon and Bryum species).
Data were collected by experienced field ecologists. Paper data sheets were digitised into Excel and were checked for any anomalies.

title: CO2 efflux and hydraulic data for two Scottish and four Amazonian streams 2011-13

description: The dataset contains CO2 efflux, hydraulic and water chemistry data from six field sites which vary in location, size and catchment characteristics. Measurements were made at: 
i) two sites in the UK - the River Kelvin (335 km2, semi-urban catchment) and Drumtee water (9.6 km2, peat dominated catchment);
ii) four sites in the Peruvian Amazon - Main Trail (5 km2, seasonally active stream in a rainforest catchment), New Colpita stream (7 km2, perennial stream in a rainforest catchment), La Torre river (2000 km2, rainforest catchment) and Tambopata river (14 000 km2, rainforest catchment with some small scale agriculture and gold mining). 

CO2 efflux was measured at all sites on each sampling occasion alongside a range of other parameters to enable investigation into the controls on CO2 efflux. Parameters measured include flow velocity and water depth (from which other hydraulic parameters can be calculated), DIC concentration and pH (from which pCO2 can be calculated) and water temperature. Sampling was carried out over several years, thus capturing a range of seasons and flow conditions, and at all sites, measurement locations were chosen to ensure that a range of flow intensities were included.
description: The Amazon data was collected as part of NERC funded research (NE/F005482/1). The UK data was first collected as pilot research to test the influence of velocity on efflux and then as part of a NERC-funded PhD (NE/K501098/1). The UK rivers were sampled regularly (once to three times a week) between June 2012 and December 2013. Main Trail, New Colpita, La Torre and Tambopata were sampled between February 2011 and May 2012 during three field campaigns (February to April 2011, September to December 2011 and March to May 2012).

title: Abundance of airborne pollen for nine grass species, measured by qPCR, UK, 2016-2017

description: The dataset contains abundance data of airborne pollen (including Anthoxanthum odoratum (sweet vernal-grass), Arrhenatherum elatius (false oat-grass), Cynosurus cristatus (crested dog's-tail), Dactylis glomerata (cock's-foot), Lolium perenne (perennial ryegrass), Phleum pratense (Timothy), Poa pratensis (smooth meadow-grass), grass species within the genera Alopecurus/Agrostis, and one probe that was found to be degenerate and unable to discriminate grass species. Here we used qPCR to track the seasonal progression of airborne grass pollen, in time and space. To do this we collected aerial samples from thirteen sites across the UK during the pollen seasons (May to September) of 2016 and 2017.
description: The qPCR data was collected using a QuantStudio 6 Flex Real-Time qPCR machine (ThermoFisher Scientific). Species-specific primers were designed to target the ITS2 region of abundant grass species in the UK including Anthoxanthum odoratum (sweet vernal-grass), Arrhenatherum elatius (false oat-grass), Cynosurus cristatus (crested dog's-tail), Dactylis glomerata (cock's-foot), Lolium perenne (perennial ryegrass), Phleum pratense (Timothy), Poa pratensis (smooth meadow-grass), grass species within the genera Alopecurus/Agrostis, and one probe that was found to be degenerate and unable to discriminate grass species.

Of 1,400 daily aerial samples, 1,210 were selected for downstream molecular analysis. Samples were excluded if pollen could not be reliably extracted due to large volumes of rainwater in collection tubes.

Quantitative PCR runs with PCR efficiencies less than 85% and greater than 115% were not used for further analysis (efficiency of qPCR data used in downstream analysis ranged between 88.5% and 106%). Data points with a large standard deviation between three technical replicates (>6.95, based on the upper quartile range of the data) were removed. In addition, samples which amplified before 10 cycles and after 38 cycles were removed to reduce the chance of detecting false positive or false negative amplification respectively. The reliability of the data was evaluated based on the positive and negative controls.
