Description

The raw species and environmental data were generated by the program SimSSD4 using the following line of parameters:

1 100 100 2 5 0.5 0 15 15 0 15 15 1 2 100 5 5

The answers to the questions of the program were the following:

Transformation of species data: 3 for presence-absence, 1 for abundance data

Standard deviation of the random normal species multipliers: 1.5

Type a small positive integer to offset the random number generator for generation of data: 1
