  • This dataset contains soil respiration data from the Climoor fieldsite in Clocaenog forest, north-east Wales. Measurements began in March 1999 at the field site, and were repeated in approximately bi-weekly intervals until June 2015 (although there are some larger gaps for technical or logistical reasons in this 14 year dataset). The data were collected using 3 different methods/machines over the years: static chambers, soil respiration chamber and Environmental Gas Monitor (EGM)-4 (from PP Systems), and soil respiration chamber and Automated Soil Gas Flux System Li8100 (from Licor Biosciences). The method used is detailed in the data and described further in the supporting documentation. Data was collected by CEH staff and PhD students trained in the use of the different methods / machines. Climoor is a climate change manipulation experiment that utilises automated roof technology to produce drought and warming experimental treatments that reflect climate change predictions for the next 20-30 years.

  • [THIS DATASET HAS BEEN WITHDRAWN]. This dataset contains soil respiration data from the Climoor fieldsite in Clocaenog forest, north-east Wales. Measurements began in March 1999 at the field site, and were repeated in approximately bi-weekly intervals until Oct 2013 (although there are some larger gaps for technical or logistical reasons in this 14 year dataset). The data were collected using 3 different methods/machines over the years: static chambers, soil respiration chamber and EGM-4 (from PP Systems), and soil respiration chamber and Li8100 (from Licor Biosciences). The method used is detailed in the data and described further in the supporting documentation.

  • This dataset includes key photosynthesis and respiration data collected from three common garden sites along an elevation/temperature gradient in the Colombian Andes. Raw A-Ci data, the Vcmax (carboxylation of RuBP by the enzyme Rubisco) and Jmax (the regeneration of RuBP by the electron transport chain) values estimated from this data, and Rdark (leaf dark respiration) values collected using spot measurements, are all available, along with variables such as leaf temperature (°C), relative humidity (%) and pressure values (kPa) returned by the LI-6800 portable photosynthesis system.

  • This dataset includes measurements of carbon-14 transfer from plants to soil within mesh cores. Measurements were taken in roots, shoots, soil and from respiration. Mesh cores were either static or rotated to provide plus and minus mycorrhizal mycelial systems. Carbon-14 was traced through cores as respiration using KOH (Potassium hydroxide) traps. The experiment was carried out at the University of Sheffield using soil from the NERC Soil Biodiversity site in Scotland. The work was part of the NERC Soil Biodiversity Thematic Programme, which was established in 1999 and was centred upon the intensive study of a large field experiment located at the Macaulay Land Use Research Institute (now the James Hutton Institute) farm at Sourhope in the Scottish Borders. During the experiment, the site was monitored to assess changes in above-ground biomass production (productivity), species composition and relative abundance (diversity).

  • This dataset contains greenhouse gas flux data and vegetation survey data from an experiment based at Parsonage Down, UK. The vegetation survey comprises total species percentage cover and species richness data from four 50 cm by 50 cm quadrats. The greenhouse gas flux data comprises net ecosystem carbon dioxide exchange, photosynthesis and respiration data measured with an Infra-red Gas Analyser (IRGA); methane, carbon dioxide and nitrous oxide data measured using gas chromatography; and nitrate and ammonium from soil samples extracted with potassium chloride. The experiment investigated the effect of different plant groups on soil carbon stores and nutrient cycling, by using a mixture of hand weeding and herbicide spot spraying to create different plant communities on the species rich grassland at Parsonage Down. The resulting carbon and nutrient cycling rates were compared to the characteristics of the plant groups. The experiment ran from 2013 to 2015 and this dataset contains data from 2014 only. This experiment was part of the Wessex BESS project, a six-year (2011-2017) project aimed at understanding how biodiversity underpins the ecosystem functions and services that landscapes provide.

  • The data include temperature and relative humidity (RH) values recorded every minute inside and outside whole-tree, passive heating, open top chambers. Respiration and photosynthesis rates were recorded (at incremental controlled leaf temperatures) on leaves on study individuals of Erythroxylum suberosum growing inside and outside the chambers. Temperature, RH, and solar irradiance were measured every fifteen minutes by local weather station are also included for the whole testing period, June to September 2020, in an area of typical Cerrado, Bacaba Park, Nova Xavantina, Brazil. The data were collected to enable development of methodology and testing of, a novel in situ passive heating method for evaluating whole-tree responses to daytime warming in remote environments using an open top chamber.

  • This dataset includes measurements of microbial community composition by phospholipid fatty acid (PLFA) analysis, soil respiration (Carbon dioxide (CO2)), soil physico-chemical properties and 13C enrichment in CO2 samples and microbial Phospholipid Fatty Acids (PLFAs). Data were produced for an investigation of the effects of carbon (C) substrate addition on soil carbon cycling processes in ten tropical soils from the Peruvian Andes. Soils were amended with 13C labelled substrates (xylose, glycine, vanillin and hemicellulose) and incubated under controlled conditions for seven days.
