The function estimates mass (g) from length (m) for a variety of taxa.

mass_from_length(l, taxon)

## Arguments

l

numeric vector of length (m). Can be 1 or more values.
Snout-vent length is used for amphibians and reptiles, except turtles where length is carapace length.

taxon

character taxon of organism, current choices: "insect", "lizard", "salamander", "frog", "snake", "turtle".

## Value

numeric mass (g).

## Details

All models follow (m = a lb) with mass in grams and length in meters.
