Microbial Niche Measurements
Measures niche breadth and overlap of microbial taxa from large matrices.
Niche breadth measurements include Levins' niche breadth (Bn) index, Hurlbert's Bn
and Feinsinger's proportional similarity (PS) index. (Feinsinger, P., Spears, E.E.,
Poole, R.W. (1981) <10.2307>). Niche overlap measurements include
Levin's Overlap (Ludwig, J.A. and Reynolds, J.F. (1988, ISBN:0471832359)) and a Jaccard
similarity index of Feinsinger's PS values between taxa pairs, as Proportional Overlap.10.2307>
