Dataset Description

Data are from a long-term fire manipulation experiment in the Missouri Ozarks, USA. Data include the raw, annual ring-width increment (rwl), basal area increment (BAI), population-level annual growth resistance (Drs) and resilience (Drl) to drought, intrinsic water use efficiency values (WUEi) and oxygen isotopic composition of individual radial growth rings (δ18O) from southern red oak (Quercus falcata) and post oak (Q. stellata) trees.

TITLE:
Data for "Sixty-five years of fire manipulation reveals climate and fire interact to determine growth rates of Quercus spp."

----------------------
FILE OVERVIEW:
This dataset contains four (4) CSV files as described below:
Refsland_et_al_ECS20-0465_BAI.csv: annual basal area increment between 1948-2015 for trees across the fire manipulation experiment
Refsland_et_al_ECS20-0465_DroughtIndices.csv: population-level drought resistance and resilience of trees during each target drought period
Refsland_et_al_ECS20-0465_WUEi.csv: carbon isotope indicators of drought stress for trees across the fire manipulation experiment
Refsland_et_al_ECS20-0465_d18Or.csv: oxygen isotope indicators of drought stress for trees across the fire manipulation experiment

----------------------
VARIABLE EXPLANATION:
All the variables in those four files are explained as below:

treeID: unique character string that identifies subject tree
block: integer (1, 2) that identifies the study block
plot: integer (1-12) that identifies the plot nested within each study block
trt: character string (Annual, Control, Periodic) that identifies the fire treatment of a given plot
species: character string (Quercus falcata, Quercus stellata) that identifies species of subject tree
year: integer (1948-2015) that identifies the dated year of each tree ring
rwl_mm: numerical value representing the annual tree ring-width, in mm
bai_cm2: numerical value representing the annual basal area increment, in cm2

timeperiod: integer value (1953, 1964, 2007, 2012) representing the periods encompassing target dry and wet years
Drs_2yr: numerical value representing the drought resistance, defined as the population-level annual growth of trees during drought years relative to pre-drought years for a given time period
Drl_2yr: numerical value representing the drought resilience, defined as the population-level annual growth of trees following drought years relative to pre-drought years for a given time period
stand_ba_m2ha: numerical value representing the total basal area of a given plot, in m2 per ha
stand_density_stems_ha: numerical value representing the total stem density of a given plot, in stems per ha

pool: numerical value (1-40) identifying the set of tree ring samples pooled for analysis. Samples were pooled by block, plot, year and species
period: integer value (1953, 1964, 1980, 2007, 2012) representing the periods encompassing target dry and wet years
type: character string (Dry, Wet) indicating the water availability of a given year
d13C: numerical value representing the carbon isotopic composition of radial growth rings within a given sample pool, in per mil
WUEi: numerical value representing the annual intrinsic water use efficiency of radial growth rings within a given sample pool
d18O: numerical value representing the oxygen isotopic composition of radial growth rings within a given sample pool, in per mil
