lma: Generate a suite of leaf mass per area results

In dilp: Reconstruct Paleoclimate and Paleoecology with Leaf Physiognomy

Generate a suite of leaf mass per area results

Description

lma() takes either raw or processed leaf physiognomic data and returns leaf mass per area (LMA) reconstructions of species-mean, site-mean, and site- variance.

lma() calls calc_lma() multiple times with different sets of parameters. See calc_lma() for more control over LMA reconstructions.

Usage

lma(specimen_data)

Arguments

specimen_data

A table that must include "Site", "Morphotype", and either "Petiole Metric", or "Blade Area", "Petiole Area", and "Petiole Width".

Value

A list of tables containing leaf mass per area reconstructions.

• species_mean_lma contains the average LMA for each morphospecies-site pair. Values calculated using the regression from Royer et al. (2007).

• royer_site_mean_lma contains the average LMA for each site. Values calculated using the regression from Royer et al. (2007)

• lowe_site_lma contains the average LMA for each site. Values calculated using the regression from Lowe et al. (2024)

• lowe_variance contains the variance in LMA for each site. Values calculated using the regression from Lowe et al. (2024)
