This file explains contents of each dataset that accompany: Roskilly et al 2019 ms. Conflicting functional effects of xylem pit structure relate to the growth-longevity trade-off in a conifer species. Dataset: BAI_age_pub_data.csv Description: Growth rates by age data per year for each sampled tree. Cambial age = estimated cambial age of tree per year MB3P197,... = names of individual trees and basal area increment (cm2 per year) Datasets: MB3P076_pub_data.csv; MB3P078_pub_data.csv; MB3P085_pub_data.csv; MB3P088_pub_data.csv; MB3P093_pub_data.csv; MB3P097_pub_data.csv; MB3P107_pub_data.csv; MB3P114_pub_data.csv; MB3P197_pub_data.csv; MB3P318_pub_data.csv; MB3P319_pub_data.csv; MB3P322_pub_data.csv Description: Age, size, growth rates, pit and tracheid data for each tree at Mackay Bar site (12 total). Tree = individual tree name Age = age class of tree (>350 years = OLD, <150 years = YOUNG) Growth = growth class of tree (lifetime BAI >30 cm2 per year = FAST, <25 cm2 per year = SLOW) LT.BAI = average lifetime basal area increment (cm2 per year) DCH = trunk diameter at coring height (cm; back-calculated based on diameter measured in the field minus ring widths to year xylem sampled) Year = calendar year sampled Tracheid = individual tracheid number TD = diameter of individual tracheid (micrometers) Pit = individual pit number Dm = average diameter of individual pit membrane (micrometers) Dt = average diameter of torus (micrometers) Da = average diameter of pit aperture (micrometers) O = torus overlap, calculated as Dt-Da/Dm-Da Dataset: Site_tracheid_pub_data.csv Description: Tracheid and growth rate data for comparison across sites. Site = site from which tree was sampled (BR = Bullion Ridge, MB = Mackay Bar) Tree = individual tree name Cat = age-growth class of tree (YS = young slow, YF = young fast, OS = old slow) Growth = growth class of tree (average lifetime BAI >30 cm2 per year = Fast, <25 cm2 per year = Slow) LT.BAI = average lifetime basal area increment (cm2 per year) Year = calendar year sampled Tracheid = individual tracheid number Diameter = diameter of individual tracheid (micrometers) Dataset: Site_pit_pub_data.csv Description: Pit dimensions and growth rate data for comparison across sites. Site = site from which tree was sampled (BR = Bullion Ridge, MB = Mackay Bar) Tree = individual tree name Age = age class of tree (>350 years = Old, <150 years = Young) Growth = growth class of tree (average lifetime BAI >30 cm2 per year = Fast, <25 cm2 per year = Slow) Year = calendar year sampled LT.BAI = average lifetime basal area increment (cm2 per year) Pit = individual pit number Dm = average diameter of individual pit membrane (micrometers) Dt = average diameter of torus (micrometers) Da = average diameter of pit aperture (micrometers) O = torus overlap, calculated as Dt-Da/Dm-Da
