store actual individual fecundity #8

Closed mdahirel closed 3 years ago

what it says in the title

right now the true fecundity F of each individual is drawn from a Poisson(\lambda) distribution where \lambda is density-dependent, but the F of each individual is not stored anywhere, juste generated and discarded.

But it'd be useful to store these F for individual from core/edge patches and neighbour patches to get the fitness advantage of dispersal strategies

So:

add an individual-level fecundity variable
add an intermediate step where the random-poisson draw for fecundity is stored, and then used to hatch offspring

*linked to #1 in that whether or not we store neighbouring patches in addition to "main" edge and core will depend on how we organise the life cycle around dispersal and reproduction
