title: Shifts in wood anatomical traits after a major hurricane

description: Trait variation across individuals and species influences the resistance
 and resilience of ecosystems to disturbance, and the ability of
 individuals to capitalize on post-disturbance conditions. In trees, the
 anatomical structure of the xylem directly affects plant function and,
 consequently, it is a valuable lens through which to understand resistance
 and resilience to disturbance. To determine how hurricanes affect the wood
 anatomy of tropical trees, we characterized a set of anatomical traits in
 wood produced before and after a major hurricane for 65 individuals of ten
 Puerto Rican tree species. We quantified variation at different scales and
 determined trait shifts between the pre- and post-hurricane periods. We
 also assessed correlations between traits and growth rates. While the
 majority of anatomical trait variation occurred among species, we also
 observed substantial variation within species and individuals. Within
 individuals, we found significant shifts for some traits that generally
 reflected increased hydraulic conductivity in the post-hurricane period.
 We found weak evidence for an association between individual xylem
 anatomical traits and diameter growth rates. Ultimately, within-individual
 variation of xylem anatomical traits observed in our study could be
 related to post-hurricane recovery and overall growth (e.g., canopy
 filling). Other factors, however, likely decouple a relationship between
 xylem anatomy and diameter growth. While adjustments of wood anatomy may
 enable individual trees to capitalize on favorable post-disturbance
 conditions, these may also influence their future responses or
 vulnerability to subsequent disturbances.

 [https://doi.org/10.5061/dryad.31zcrjdsf](https://doi.org/10.5061/dryad.31zcrjdsf) ## Description of the data and file structure This dataset is the summary data used in the main analysis of the paper: Zieminska *et al.* (2023) Shifts in wood anatomical traits after a major hurricane. *Functional Ecology*. Any cells with "NA" values indicate that we were unable to compute a given variable for a given individual (e.g., if there was insufficient wood produced during one of the periods to measure anatomical traits). **Table 1.** Each row contains the following information for each individual tree sampled. Refer to the main article for detailed information on how the samples were collected and processed, as well as more information on the specific anatomical traits measured. | Variable | Details | | -------- | ------- | | Species | Species 6-letter code (first 3 letters of genus + first 3 letters of species; see Table 2 of the main manuscript) | | Tag | Tree tag from the Lquillo Forest Dynamics Plot | | DBH | Diameter of the tree at 1.3 m during sampling (July 2020) | | Damage | Hurricane damage category assigned during sampling (July 2020) (1=low, 2=medium, 3=high) | | abs\_post\_growth\_mm | Absolute diameter growth (mm) in the post-hurricane period | | sample\_area\_mm2\_pre | Sample area for the pre-hurricane section | | sample\_area\_mm2\_post | Sample area for the post-hurricane section | | area\_50q\_um\_pre | Median vessel area (A50) in the pre-hurricane portion of the sample | | area\_50q\_um\_post | Median vessel area (A50) in the post-hurricane portion of the sample | | area\_95q\_um\_pre | Area of the 95th percentile of vessels (A95) in the pre-hurricane portion of the sample | | area\_95q\_um\_post | Area of the 95th percentile of vessels (A95) in the post-hurricane portion of the sample | | area\_skew\_pre | Skew of vessel area (Vskew) in the pre-hurricane portion of the sample | | area\_skew\_post | Skew of vessel area (Vskew) in the post-hurricane portion of the sample | | Kh\_Dcircle\_tot\_mm2\_pre | Area-based theoretical hydraulic conductivity in the pre-hurricane portion of the sample | | Kh\_Dcircle\_tot\_mm2\_post | Area-based theoretical hydraulic conductivity in the post-hurricane portion of the sample | | pre\_frac\_npts | Number of sample points used to estimate the post-hurricane tissue fractions | | post\_frac\_npts | Number of sample points used to estimate the pre-hurricane tissue fractions | | frac\_vessel\_pre | Vessel fraction (Fves) for the pre-hurricane section | | frac\_vessel\_post | Vessel fraction (Fves) for the post-hurricane section | | frac\_fiber\_pre | Fiber fraction (Ffib) for the pre-hurricane section | | frac\_fiber\_post | Fiber fraction (Ffib) for the post-hurricane section | | frac\_parenchyma\_total\_pre | Total parenchyma fraction (Fpar(total)) for the pre-hurricane section | | frac\_parenchyma\_total\_post | Total parenchyma fraction (Fpar(total)) for the post-hurricane section | | frac\_axial\_pre | Axial parenchyma fraction (Fpar(axial)) for the pre-hurricane section | | frac\_axial\_post | Axial parenchyma fraction (Fpar(axial)) for the post-hurricane section | | frac\_ray\_pre | Ray parenchyma fraction (Fpar(ray)) for the pre-hurricane section | | frac\_ray\_post | Ray parenchyma fraction (Fpar(ray)) for the post-hurricane section | | ves\_density\_mm2\_pre | Vessel density in the pre-hurricane portion of the sample | | ves\_density\_mm2\_post | Vessel density in the post-hurricane portion of the sample | | ves\_grp\_index\_pre | Vessel grouping index (Vgrp) in the pre-hurricane sample | | ves\_grp\_index\_post | Vessel grouping index (Vgrp) in the post-hurricane sample | | pre\_growthrate\_mmyr | Estimated post-hurricane stem diameter growth rate (mm/year) | | pre\_BAgrowthrate\_m2yr | Estimated post-hurricane stem basal area growth rate (m2/year) | | post\_growthrate\_mmyr | Estimated pre-hurricane stem diameter growth rate (mm/year) | | post\_BAgrowthrate\_m2yr | Estimated pre-hurricane stem basal area growth rate (m2/year) | **Table 2.** List of species included in the study. | **Family** | **Species** | **Authority** | **N** | **Species code** | | ------ | ------- | --------- | --- | ------------ | | Salicaceae | *Casearia arborea* | (Rich.)
