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

Description

Calculates foraging distance from Greenleaf et al. (2007) using intertegular distance (ITD) values, van Nieuwstadt and Iraheta (1996) using head width (HW) values for Meliponini (stingless bees) and Guedot et al. (2009) using dry weight (mg) values for Osmia species.

Usage

foragedist(x, type = "GreenleafAll")

Arguments

x	A vector of either bee intertegular spans (IT) measurements in cm, head width values in mm or dry weight values (mg).
type	The type of foraging distance desired. Options are "GreenleafAll", GrMhd ("Maximum homing distance"), GrThd ("Typical homing distance"), GrMfd ("Maximum feeder training distance"), GrMcd("Maximum communication distance"),"Osmia", "MeliMR" , "MeliFT" or "MeliAll". See details in Greenleaf et al. (2007), Guedot et al. (2009) and van Nieuwstadt and Iraheta (1996).

Value

A dataframe with bee and foraging distance (Km) is returned for each bees species.
