newArrivals_t: Number of newly immigrating species
In thauffe/simGDM: simGDM

Description Usage Arguments Value Author(s) References

This function calculates the number of newly immigrating species (Equation 2 in Appendix 2 of Borregaard et al. 2016)

1 2	newArrivals_t(Imm, Ms, Iso_t, NewSpecies_t, Area_t = 1, Elevation_t = 1)

`Imm`	The probability of one species arriving from the mainland per time step
`Ms`	Species richness of the mainland source pool
`Iso_t`	A descriptor of island isolation in arbitrary units
`NewSpecies_t`	Probability that an immigrant species is not already on the island
`Area_t`	Island area at moment t, to simulate the target effect (not included in Borregaard 2016)
`Elevation_t`	Island elevation at moment t, to simulate the target effect (not included in Borregaard 2016)
