EvoLaps: a web interface to visualize continuous phylogeographic reconstructions


EvoLaps aims at visualizing spatio-temporal spread of epidemics, from phylogenetic trees associated with continuous localities (computed ancestral latitude/longitude pairs associated with computed ancestral sequences).

Changes of localities ('transitions'), in a "Top-Down" reading of the tree, are represented on a cartographic background using arcs between them. The bundle of arcs is a phylogeographic scenario. EvoLaps helps to analyze complex scenarios:

  • analysis of transitions with dynamic highlight and selection tools ;
  • synthetise a scenario with an iterative clustering process, from continuous localities to more or less large regions, keeping details of specific phases of it ;
  • corroborate third party variables by computation of ancestral character states from discrete variables and their superimposition on phylogeographic scenarios.
