do.competition: Implement seed competition
In akeyel/spatialdemography: A Spatially Explicit Metacommunity Model
Description
Idea is that seeds will compete for microsites. Currently three types of competition possible:
0 = no competition, 1 = within-species K (excess seeds die), 2 = deterministic
multi-species K (seeds are assigned to microsites proportional to the number of seeds
of each species), and 3 = stochastic multi-species K (seeds are assigned to microsites
via a lottery approach, where each seed has a chance to occupy a microsite.
NOTE: Seeds already in the seedbank occupy microsites, juveniles and adults do not.
WARNING: My implementation of this may be computationally intensive for large numbers of seeds!
Usage
1
2
do.competition(competitiontype, microsites.vec, nt1a.lst, spe, ISeedBank,
ISeedlings, p)
Arguments
competitiontype
The type of competition (see description)
microsites.vec
A vector giving the number of microsites in each cell.
nt1a.lst
A list giving the abundances of each of the four stages for each species
spe
The number of species in the regional species pool
ISeedBank
An index for which entries for each species in nt1a.lst correspond to stage 1 individuals.
ISeedlings
An index for which entries for each species in nt1a.lst correspond to stage 0 individuals.
p
Number of cells in the landscape
