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.

Nematode species were extracted from two species of bryophyte (Cephaloziella varians and Sanionia uncinata) in a vegetated gully on Rothera Point, Adelaide Island. Nematode species were extracted from 10 fixed plots: five control plots, and five warmed plots (covered with open top chambers for the duration of the experiment). Sampling occurred over eight days between 2007 and 2010. The total number of nematodes in each sample, along with the numbers of males, females and juveniles of each species, were recorded and expressed per gram dry weight of bryophyte colony. The numbers of gravid females of Plectus belgicae, along with the total number of eggs in gravid females, were also recorded at four of the samplings.
The datasets consist of three csv files containing: (i) the numbers of DNA reads of 415 operational taxonomic units of fungi in 64 plots of a soil warming experiment sampled in 2007, 2009, 2010, 2011 and 2012, (ii) the taxonomic placements of the fungi and (iii) the treatments applied to the plots. The research was funded by an Antarctic Funding Initiative grant from the UK Natural Environment Research Council (NE/D00893X/1), a NERC GW4+ Doctoral Training Partnership studentship (grant number NE/L002434/1), NERC core funding to the British Antarctic Survey Long Term Monitoring and Survey programme, and monies derived from the University in Svalbard Arctic Mycology course (for which reference numbers are not available).
