The datasets contain insect numbers, plant biomass, successful attacks of parasitoids, and behavioural response of parasitoids. The data have been sampled as part of the NERC project NE/N001672/1 "Effects of artificial light on multi-trophic population dynamics". The data are based on direct observations of insects and plants in field and laboratory experiments testing for the impact of different intensities of artificial light at night on an experimental insect food web with control (no light), and white LED light with 0.1,1,5,10,20,50,100 lux. Data collection was done in a field site, and controlled temperature room at Penryn Campus of University of Exeter, Penryn, UK. The field experiment was set up on 29th July 2016 and ran for nine weeks, while the additional experiments were conducted between summer 2016 and spring 2018.

Description of peatland sites included in the compilation of carbon accumulation rates, including resolution (high, low), interpolation (yes/no), contributor name, country, lon, lat, peatland type, dominant plant type, no. of dates used in the last millenium carbon accumulation rate calculation, and problems with the data. Peatland sites at northern hemisphere high and mid latitudes (260), tropical (30) and southern hemisphere high latitudes (7 sites).
This dataset comprises raw carbon, oxygen and hydrogen stable isotope data on water (precipitation and terrestrial) and plant cellulose from Empodisma-dominated peatlands throughout New Zealand. This data has been published in two open access papers: Amesbury, M. J., Charman, D. J., Newnham, R. M., Loader, N. J., Goodrich, J. P., Royles, J., Campbell, D. I., Roland, T. P. and Gallego-Sala, A. V. 2015. Carbon stable isotopes as a palaeoclimate proxy in vascular plant dominated peatlands. Geochimica et Cosmochimica Acta 164, 161-174. Amesbury, M. J., Charman, D. J., Newnham, R. M., Loader, N. J., Goodrich, J. P., Royles, J., Campbell, D. I., Keller, E. D., Baisden, W. T., Roland, T. P. and Gallego-Sala, A. V. 2015.

Benthic stable isotope (carbon and oxygen) data from IODP Site U1445. Generated by Yasmin Bokhari-Friberg, supervisied by Kate Littler and Pallavi Anand.
We report sedimentary coatings and fish teeth neodymium isotope values – tracers for water-mass mixing – from deep-water International Ocean Discovery Program (IODP) Site U1438 (4.7 km water depth) in the Philippine Sea, northwest Pacific Ocean. The time period encompasses the last 20 million years.
Non-contact Atomic Force Microscopy images (NC-AFM) of surface nanobubbles on the carbonate mineral dolomite. Since surface nanobubbles were first imaged in 2000, they have been of growing interest to research due to their long lived properties, with reported lifetimes as long as several hours. Images of nanobubbles were produced under water, collector and depressant conditions using the air water supersaturation method. These are the first images of surface nanobubbles on dolomite. Surface nanobubbles could play a part in the processing of dolomite via froth flotation. These images lay a foundation for future analysis of the effect of nanobubbles in flotation.
Zeta potential measurements of rare earth element enriched apatite from Jacupiranga, Brazil under water and collector conditions. Zeta potential measurements can be used to indicate the surface behaviour of a mineral under different reagent conditions. Mineral surface behaviour is important in processing and extracting minerals from their host ore, which can be energy intensive. Apatite is a phosphate mineral which can become enriched with rare earth elements. Rare earth elements are important in a wide range of products from iPhones to wind turbines.
This data was generated at the University of Kiel, Germany by Wolfgang Kuhnt, paid for by Dr Littler as part of her 2016 NERC Moratorium Award. The data comprises XRF-derived elemental abundances from two Holes (A and B) for International Ocean Discovery Program (IODP) Site U1448, spanning approximately the Pliocene period.
Non -contact atomic force microscopy (NC-AFM) images of surface nanobubbles on the fluorcarbonate mineral synchysite. Synchysite is a rare earth fluorcarbonate mineral which has previously been relatively unstudied. Since nanobubbles were first imaged in 2000, they have been thought to play a intigral role in mineral processing. Images of nanobubbles were produced under collector reagent conditions favourable to flotation. These are the first images of nanobubbles on the fluorcarbonate mineral synchysite. Nanobubbles at the surface of synchysite improve the understanding of both flotation and nanobubble formation.
This document is the drillers log of strata encountered during site investigation work. The log was made in the field during drilling at Prees, Shropshire on 8th to 10th January 2020. The log includes basic information on lithology and drilling equipment used and depths of the individual core runs.
