Description Usage Arguments Format Details Author(s) See Also

A spatially-explicit model of resilience in arid rangelands.

1	ca(l, livestock, parms = p)

`b`	environmental quality
`m`	intrinsic plant mortality, i.e. inverse of av. lifespan
`r`	max. regeneration rate of plants
`K`	carrying capacity of the landscape (i.e. global competition)
`f`	local facilitation
`c`	local competition
`L`	livestock density
`a`	attack rate of livestock
`h`	handling time of livestock
`q`	hill-exponent of livestock
`p`	associational resistance against livestock grazing
`v`	attractant-decoy effect of plants to livestock

An object of class ca_model of length 6.

An unpublished, generalized model of positive and negative local feedbacks in arid rangelands, including mechanisms such as local facilitation, competition, associational resistance and attractant-decoy.
