fn.lambda: Calculate recruitment bias based on environmental filtering

In sokole/MCSim: Metacommunity simulations for ecologists

Calculate recruitment bias based on environmental filtering

Description

Used by fn.metaSIM. Uses niche breadth and an environmental gradient to determine how to bias species selection weights based on environmental filtering dynamics. See Gravel et al. 2006.

Usage

fn.lambda(trait.optimum, niche.breadth, Ef, Ef.specificity)

Arguments

trait.optimum	Optimum value for a given species along an environmental gradient. Gradients in fn.metaSIM are restricted to the range [0,1], so this value must be in the range [0,1].
niche.breadth	Niche breadth around a species' trait optimum. The value of sigma in Fig 1 in Gravel et al. (2006).
Ef	Value of the environmental filter at the site for which lambda is being calculated.
Ef.specificity	The selection specificity of the environmental filter.

Details

Used by fn.metaSIM.
