########################### TTS GAP DYNAMICS DATA ############################# # # This readme and the associated three data files were prepared by Michael K. # Fell in January 2018. # # Please contact me if you have any questions: michael.fell@nau.edu # # Note this text file should be displayed in a window at least 80 columns wide. # This having at least 80 columns is common in operating systems such as # Ubuntu and forks based on it. # ############################################################################### ##### FILE 1: tree_mort.csv ##### This file contains tree level mortality (mgp). This file can be used to calculate the mortality data in the other two files. gap.sim - The simulation number (1 to 62) index - An index matching rows in theta_final_with_mort.csv. Used for linking data between the two files. dead - 1 if the tree died and 0 if it survived. ##### FILE 2: stand_mort.csv ##### This file contains the simulation or stand level mortality. It also has the average light level for each of the 62 gap simulations in this study (PARavg). gap.sim - The simulation number (1 to 62) PARavg - Average light for each gap simulation (MJ m^-2, year^-1). stand.mort - Stand level mortality (simulation mortality, msg) 62 entries one for each gap dynamics simulation. ##### FILE 3: parameters_with_phenotype_mort.csv ##### This file combines trait data and phenotype level mortality. The vector of traits in columns 1 to 32 in each of the 33,000 rows can be thought of as a phenotype. The last two columns (PAR and m.thetap) represent the light level used when fitting the ACGCA model to FIA data in previous work and m.thetap is the phenotype level mortality (m theta p). hmax - Maximum tree height (m) phih - Slope at H versus r curve at r = 0 m (unitless) eta - Relative height at which trunk transitions from paraboloid to cone (unitless) swmax - Maximum sapwood width (m) lamdas - Proportionality between BT and BO for sapwood (unitless) lamdah - Proportionality between BT and BO for heartwood (unitless) rho - Wood density (g dw m^-3) f2 - Fine root area to leaf area ratio (unitless) f1 - Leaf area to xylem conducting area ratio (unitless) gammac - Maximum storage capacity of living sapwood cells (g gluc m^-3) gammax - Xylem conducting area to sapwood area ratio (unitless) cgl -Construction costs of producing leaves (g gluc g dw^-1) cgr - Construction costs of producing fine roots (g gluc g dw^-1) cgw - Construction costs of producing sapwood (g gluc g dw^-1) deltal - Labile carbon storage capacity of leaves (g gluc g dw^-1) deltar - Labile carbon storage capacity of fine roots (g gluc g dw^-1) sl - Senescence rate of leaves (year^-1) sla - Specific leaf area (m^2 g dw^-1) sr - Senescence rate of fine roots (year^-1) so - Senescence rate of coarse roots and branches (year^-1) rr - Average fine root radius (m) rhor - Tissue density of fine roots (g dw m^-3) rml - Maintenance respiration rate of leaves (g gluc g dw^-1 year^-1) rms - Maintenance respiration rate of sapwood (g gluc g dw^-1 year^-1) rmr - Maintenance respiration rate of fine roots (g gluc g dw^-1 year^-1) etaB - Relative height at which trunk transitions from neiloid to paraboloid (unitless) k - Crown light extinction coefficient (unitless) epsg - Radiation-use efficiency (g gluc MJ^-1) m - Maximum relative crown depth (unitless) alpha - Crown curvature parameter (unitless) R0 - Maximum potential crown radius of a tree with diameter at breast height of 0 m (i.e., for a tree that is exactly 1.37 m tall) (R0 is in m) R40 - Maximum potential crown radius of a tree with diameter at breast height of 0.4 m (40 cm) (R40 is in m). PAR - the light level used when fitting the ACGCA model to FIA data. Each parameter set represents a single MCMC output from a Bayesian model (MJ m^-2, year^-1) m.thetap - phenotype level mortality (m theta p) (unitless) ############################# ACKNOWLEDGEMENTS ################################ This work was partially supported by an NSF-Division of Biological Infrastructure grant to K.
