tonguelength {pollimetry}

Converts ITD (cm) to tongue length for bees.

Description

Calculates tongue length (mm) from Cariveau et al. (2015) using intertegular distance (ITD) values (cm)..

Usage

tonguelength(x, mouthpart = "all")

Arguments

x

A dataframe with the following two columns: bee intertegular distance (IT) measurments in mm and Family, a vector of bee families. Only implemented 5 out of the extant 7 families: "Andrenidae", "Apidae", "Colletidae", "Halictidae", "Megachilidae".

mouthpart

The mouth part you are interested in. Options are "all", glossa", "prementum" and "tongue" (i.e. gloss + prementum)

Value

A dataframe with bee tongue length (mm) and 95
