fc

Calculates the functional complementarity for the rows of a web

Description

A community-level measure of ecological niche complementarity measured as the total branch length of a functional dendrogram based on qualitative differences in visitor assemblages between plants.

Usage

fc(web, dist="euclidean", method="average", weighted=TRUE)

Arguments

`web`	A bipartite interaction web, i.e.~a matrix with higher (cols) and lower (rows) trophic levels.
`dist`	A distance accepted by the function `dist`.
`method`	The linkage method to be used by `hclust`. Any option accepted by `hclust` is allowed; defaults to "average".
`weighted`	Option to analyse the web as binary or as weighted network. Default is weighted=TRUE, but analysis presented in Devoto et al. (2012) uses weighted=FALSE.

Details

fc measures community-level ecological niche complementarity as the total branch length of a functional dendrogram based on qualitative differences in visitor assemblages between plants. For details see Devoto et al. (2012).

Value

The value of fc, which is not standardised and lies anywhere between 0 and a large number.
