Summary of contributions

The work was envisioned by DG. RT and DG jointly led the research. RT, CHF and DA developed the thermal tolerance protocols with inputs from HGK. RT trained the teams led by WJAC and SMR in thermal tolerance measurements; BSM and BHM oversaw the field campaign. IAS collected additional data from Cerradão forest, Nova Xavantina. DMS sampled trees with support from CHLO, EQM and WJAC. MS, KW and HGK provided data for Panama. Remaining team members assisted with thermal tolerance measurements. RT wrote the manuscript with primary support from DG and additional support from EG, CHF and SF. All co-authors commented on the manuscript.
