In pollimetry: Estimate Pollinator Body Size and Co-Varying Ecological Traits

Description

Calculates dry body weight (mg) using head width (mm) from Hodar (1997).

Usage

headwidthsize(HW, Eq = "H97DB")

Arguments

HW	A vector of head width measurements (mm).
Eq	a vector of predictive allometries for insect taxa from Hodar (1997). Options implemented are: H97DB (Brachycera), H97DN (Nematocera), H97HA (Hymenoptera), H97LH (Heterocera) and H97LR (Rhopalocera).

Value

A dataframe with pollinator body size as dry weight (mg) is returned for each specimen from selected equation.
