WebFeb 1, 2011 · Unfortunately, some authors have equated the concept of nestedness with the matrix temperature index and pointed out that nestedness is a measure of order (i.e., the inverse of entropy). Actually, any non-random metacommunity pattern (see examples in Leibold and Mikkelson, 2002 , Hausdorf and Hennig, 2007 ) is a measure of order, but …
