Corridors and reservoirs: An analysis of inter-Andean historical biogeography

The Andes are a global biodiversity hotspot, and the formation of this mountain range has been linked to the rapid diversification of numerous lineages across the Tree of Life. In addition to generating high species richness, the Andes may have functioned as a reservoir from which lineages dispersed across South America. Recent syntheses of Andean geological history, together with the growing number of phylogenetic studies across diverse Andean clades, provide an opportunity to integrate current knowledge of the historical biogeography of the Andean biota. Here, we present a meta-analysis of phylogenetic studies in which we scored disjunction events within and out of the Andes based on published biogeographic reconstructions. Across clades and through time, dispersal events within the Andes were approximately as frequent as those out of the Andes. The highest number of extra-Andean disjunctions originated in the northern Andes, despite this region being the most recently uplifted.

## Description of the data and file structure

Using a Python script, we performed three rounds of web scraping of Google Scholar search results for the keyword “Andes.” Each web scraping round targeted publications that cite a specific major historical biogeographic reconstruction methodology. The first round scraped all the publications from 2014 to 2024 that cited the R package BioGeoBEARS (Matzke 2014) and returned 304 results. The second round scraped all publications from 2016 to 2024 that cited RevBayes (Höhna et al. 2016), returning 62 results. The last round scraped all publications from 2013 to 2024 that cited LagRange (Matzke 2013), returning 178 results. Among the scrape results, we excluded publications that did not perform ancestral reconstructions on a time-calibrated phylogeny, lacked at least one dispersal either ou...,
