Test of Host-Parasite Coevolution

Pierre Legendre

 This program tests the hypothesis of coevolution between a clade of hosts and a clade of parasites. The null hypothesis of the global test is that the evolution of the two groups, as revealed by the two phylogenetic trees and the set of host-parasite association links, has been independent. The method, which is described in detail in Legendre et al. (2002), requires some estimates of the phylogenetic trees or phylogenetic distances, and also a description of the host-parasite associations (H-P links) observed in nature. Two types of test are produced by the program: a global test of coevolution and a test on each H-P link.

    • Sample files: Hafner’s gopher-lice data, and a one host-one parasite example
  • 32-bit DOS version (The executable file is a Win32 "console" executable, not a DOS executable. Therefore it cannot run under plain DOS, nor in a DOS window under Windows 3.x, only in Windows 95/98 or Windows NT consoles)
    • GNU Fortran source code for Mac OS X, Unix/Linux, or Windows (file PARAFIT.FOR), which can be compiled using a GNU FORTRAN77 compiler.
    • Compiled version of the program for Win32 compatible computers
    • Program documentation, in Acrobat format
