Data supporting manuscript: Influence of vapour pressure deficit and CO₂ on the thermal sensitivity of stomatal function in tropical trees

Data set and R code supporting the New Phytologist manuscript \"Influence of vapour pressure deficit and CO2 on the thermal sensitivity of stomatal coupling in tropical trees\" Data set consists of biomass, leaf-level functional traits, and leaf-level gas exchange data from saplings of three species of tropical tree grown under controlled conditions and either ambient (420ppm) or elevated (820ppm) [CO2]. R Code attached includes that used to analyze data in the manuscript and to explore the potential temperature sensitivity of the modelling term g1 in the Medlyn et al (2011) stomatal conductance model. , Study species and experimental material We examined the behaviour of leaf-level gas exchange at elevated temperatures in three broadly distributed tropical tree species found within the Australian Wet Tropics: Mallotus philippensis (Lam.) Mull.Arg. (Euphorbiaceae), Ficus congesta Roxb. var. congesta (Moraceae) and Elaeocarpus grandis F.Muell. (Elaeocarpaceae). All plant material was obtained from a local nursery, and for each species originated from a single seed source in the lowlands. All three species show a broad geographical distribution and are typically found within the Australian Wet Tropics between sea level and 1100m. Seedlings were potted into 145mm square pots (4L) containing a high organic matter potting mix with ¼ (by volume) of a local volcanic stone, Quincan (Northside Raw Materials &amp; Timber Supplies, Cairns, Australia), to improve drainage. Before treatments, seedlings were established in a shade house (75% solar transmission) for 1 month. At the start of the experi..., # Data supporting manuscript: Influence of vapour pressure deficit and CO~2~ on the thermal sensitivity of stomatal function in tropical trees Dataset DOI: [10.5061/dryad.tdz08kqc9](https://doi.org/10.5061/dryad.tdz08kqc9) ## Description of the data and file structure Data represents information collected on saplings of three tropical tree species grown under a controlled environment conditions in Tropical North Queensland. Data incudes basic biomass, its allocation and leaf level functional traits such as leaf mass per unit area, as well as detailed leaf-level gas exchange data under varying CO~2~ and across a range in temperatures. ### Files and variables <br /> #### File: Dryad_repo_biomass.csv **Description:** Final biomass its allocation and leaf-level functional traits of six individuals of three species grown under controlled conditions and either ambient or elevated CO~2~ ##### Variables * Code: Unique experimental plant code * Group: Plant type (Eudicot) * species: On..., ,
