Margalef's richness index: (S-1)/ln(n), where S is the number of taxa, and n is the number of individuals.
Hi all, this may seem pretty simple to you all, but I admit that when it comes to numbers I struggle.
Please correct me where I (may) be getting this wrong:
[(S-1)/ln] x n = answer
My struggling point is, what is 'ln' I can't seem to find this anywhere (is it simply 1-n?).
Thanks for your help!
