length_to_mass: Converts length measures to body mass for bees and Carabids

In ibartomeus/fundiv: tools to calculate several functional trait diversity indexes

Description

For Bees, the conversion is done as per Cane et al. 1987 (Estimation of bee size using intertegular span (Apoidea). Journal of the Kansas Entomological Society 60:145–147). The correlation between IT and body mass is 0.96. For Carabids the conversion is done from Jelaska et al. 2011 (Carabid beetle diversity and mean individual biomass in beech forests of various ages. ZooKeys 100:393-405) which in turn is based on Szyszko J (1983) book.

Usage

length_to_mass(x, taxa = c("Bees", "Carabids"))

Cane(x)

Jelaska(x)

Arguments

x	A vector of bee intertegular spans (IT) measurments in cm or carabid beetles body length (mm)
taxa	string character indicating if length measure is from "Bees" or "Carabids"

Value

A vector of bee body masses is returned in (gr) for bees and for Carabids.

Examples

length_to_mass(c(1.2, 2.3, 0.6), "Bees")
Jelaska(c(1.2, 2.3, 0.6))
