  1. Each entry in the table is listed as values calculated for inversions / molecular data. The number of nodes (# of nodes), the umber of negative nodes (negative nodes) and the # number of zero nodes (zero nodes) are given in the first three columns. The percent of zero or negative nodes refers to nodes that have either zero or negative Bremer support values. Total BS is the Bremer support summed over all nodes in the cladogram. This value has been corrected by either dividing by the number of parsimony informative characters or the minimum steps in each partition (see text).
