jbi-14782	Soberón, Jorge; Cobos, Marlon E.; Nuñez-Penichet, Claudia	Visualizing species richness and site similarity from presence-absence matrices	2021	8	.pdf	application/pdf	5160	268	56	Considering how the ran- domization is done, before starting the process, we broke any potential geographic structure remaining in the PAM (where closer rows are also closer cells in the geography) by rearranging randomly the rows (which represent geographic cells) but maintaining the identity of these cells in the results. The two cases are: 1) a positive mini- mum covariance when comparing communities per site (grid cells in our case); and 2) the case with a negative minimum covariance.	cache/jbi-14782.pdf	txt/jbi-14782.txt
