Parsimony analysis of endemicity (PAE) revisited

Distribution patterns of the genus Pacifigorgia (Octocorallia: Gorgoniidae): track compatibility analysis and parsimony analysis of endemicity

Gorgonian octocorals (order Alcyonacea) are the most abundant components of shallow eastern Pacific marine communities (Breedy & Guzman, 2003a). They occur mainly in zones of strong current swell and breaking surf, attached to rocky bottoms, shells, and small rock fragments (Breedy & Guzman, 2002). Although abundant, the eastern Pacific octocoral fauna was considered poorly known by Bayer (1981...

Distribution patterns of Neotropical primates (Platyrrhini) based on Parsimony Analysis of Endemicity.

The Parsimony Analysis of Endemicity (PAE) is a method of historical biogeography that is used for detecting and connecting areas of endemism. Based on data on the distribution of Neotropical primates, we constructed matrices using quadrats, interfluvial regions and pre-determinated areas of endemism described for avians as Operative Geographic Units (OGUs). We codified the absence of a species...

New insights into the biogeography of southwestern Europe: spatial patterns from vascular plants using cluster analysis and parsimony

Methods Pattern analysis of a chorological dataset, consisting of the occurrences of 3041 vascular plant species in each of the 50 km 9 50 km UTM cells of a grid covering Iberia and the Balearic Islands, was based on cluster analysis (unweighted pair-group method using arithmetic averages; UPGMA) and parsimony analysis of endemicity (PAE). The Jaccard similarity index was used in the UPGMA, and...

Panbiogeographical analysis of Costa Rican freshwater fishes.

Track analysis and Parsimony analysis of endemicity (PAE) were performed to analyze the distribution pattern of Costa Rican freshwater fishes. A basic matrix (presence/absence) was prepared using the distribution of 77 freshwater fish. The data were analyzed with CLIQUE software in order to find generalized tracks (cliques). Data also were analyzed with the software NONA and Winclada version 1....
