“…The protocol aims to reconstruct the history of a geographic area through a sequence of vicariance events inferred from the allopatric distributions of sister taxa. This allows for reticulate and divergent patterns without assuming hierarchical relationship of areas, avoiding unrealistic assumptions prevalent in traditional cladistic biogeographical methods (56). The focus of the protocol is on detecting barriers that separate biotas, not on the relationship between predefined areas of endemism, and it is therefore suited for disentangling the origins of current distributional patterns of taxa (57) and the boundaries of our bioregions.…”

Understanding the spatial and temporal evolution of biota in the tropical Andes is a major challenge, given the region's topographic complexity and high beta diversity. We used a network approach to find biogeographic regions (bioregions) based on high-resolution species distribution models for 151 endemic bird taxa. Then, we used dated molecular phylogenies of 14 genera to reconstruct the area history through a sequence of allopatric speciation processes. We identified 15 biogeographical regions and found 26 events of isolation and diversification within their boundaries that are independently confirmed with disjunct distributions of sister taxa. Furthermore, these events are spatially congruent with six geographical barriers related to warm and/or dry river valleys, discontinuities in elevation, and high peaks separating fauna from different range slopes. The most important barrier is the Marañon River Valley, which limits the boundaries of four bioregions and is congruent with eight phylogenetic distribution breaks, separating the Central and Northern Andes, where the most bioregions are found. We also show that many bioregions have diffuse and overlapping structures, with contact and transition zones that challenge previous conceptions of biogeographical regions as spatially simple in structure. This study found evidence that the drivers of our identified bioregions were processes of Andean uplift and mountain dispersal facilitated by temperature oscillations of the Pleistocene. Therefore, Andean bioregions were not formed from one simple biogeographical event in a certain time frame, but from a combination of vicariance and dispersal events, which occurred in different time periods.

“…Areas of endemism are seen by many (Dos as the basic units in historical biogeography. Even if one agrees with recent viewpoints (Hovenkamp 1997(Hovenkamp , 2001Fattorini 2007) that vicariance analysis does not require prior recognition of areas of endemism, the notion of endemism is so pervasive in biology and biogeography that determining what these areas are and whether they exist at all is important in its own right.…”

“…a geological event or barrier which appeared and physically separated populations) is not necessarily implied by a disjunct distribution; a successful dispersal over a pre‐existing barrier resulting in speciation (as in the colonization of an oceanic island) will also produce a disjunct distribution. Therefore, focusing on disjunct distributions does not imply that vicariance is the only process allowed by the analysis (Fattorini, 2008); rather, it recognizes that a disjunct distribution implies the existence of an effective barrier to dispersal (Hovenkamp, 1997, 2001).…”

Based on HovenkampÕs ideas on historical biogeography, we present a method for analysis of taxon history, spatial analysis of vicariance, which uses observed distributions as data, thus requiring neither predefined areas nor assumptions of hierarchical relations between areas. The method is based on identifying sister nodes with disjunct (allopatric ⁄ vicariant) distributions. To do this across the tree, internal nodes are assigned distributions (as the sum of the distributions of the descendant nodes). When distributions are less than ideal, ignoring the distribution of the problematic node(s) when assigning a distribution to their ancestors may allow us to consider additional sister nodes (i.e. those resulting from splits basal to the problematic node) as having disjunct distributions. The optimality criterion seeks to find the best (possibly weighted) compromise between the maximum possible number of disjunct sister nodes and the minimum number of eliminated distributions. The method can also take overlap into account. The methodology presented is implemented in VIP, a computer program available at http://www.zmuc.dk/public/phylogeny/vip.
