effectOnConsumer: Per capita effect on consumer population.

In dswdejonge/fwstability: Infer Food-Web Stability

Per capita effect on consumer population.

Description

This function finds the per capita effect of a resource on the growth of the consumer population. It uses functions from de Ruiter et al. (1995) and Neutel et al. (2002). The flow from resource to consumer is adjusted for conversion efficiency and divided by the biomass of the resource.

Usage

effectOnConsumer(FM, BM, AE, GE)

Arguments

FM	(required) A square flowmatrix, source compartments as rows, sink compartments as columns.
BM	(required) Numeric vector with biomasses of all compartments, must be in the same order as the flow matrix FM.
AE	(required) Numeric vector with assimilation efficiencies of all compartments, must be in the same order as the flow matrix FM.
GE	(required) Numeric vector with growth efficiencies of all compartments, must be in the same order as the flow matrix FM.

Value

This function returns a matrix containing the effects of resources (rows) on consumers (columns).
