This file was prepared by Darren E. Irwin on March 3, 2012, and contains data from the following paper: Irwin, Darren E. 2012. Local adaptation along smooth ecological gradients causes phylogeographic breaks and phenotypic clustering. The American Naturalist, in press. | The format of the data is as follows: | For each set of simulations (i.e., run under the same parameter values), I first provide values for the following parameters: | set_name (an arbitrary 1- or 2-letter code to identify that set) | N (initial total population size across entire range) | sigma_disp (the width of the dispersal curve) | sigma_w (the width of the selection curve at each geographic location; the smaller this is, the stronger the selection) | mu (the mutation rate, per individual per generation) | sigma_mut (the width of the mutation size curve) | The parameters for the set are then followed by the genealogies and trait values for a series of independent simulations, as follows: | I provide the name of the genealogy (the set_name plus an integer indicating the particular simulation), followed by a long string containing the genealogy of 60 individuals from the population, in typical Newick or Nexus format (here, they are the same); this genealogy string can be copied and pasted into a program such as TreeView or some other tree-drawing program. | Individuals in the genealogy are identified by an integer as follows: | Individuals 1-10: Closest to location x=0.0 | Individuals 11-20: Closest to location x=0.2 | Individuals 21-30: Closest to location x=0.4 | Individuals 31-40: Closest to location x=0.6 | Individuals 41-50: Closest to location x=0.8 | Individuals 51-60: Closest to location x=1.0 | Branch lengths in the genealogy represent the number of generations. | Following the genealogy, I provide a table showing the trait value (y) of each individual, using the same integer identifiers of individuals as in the genealogy. | Data from different sets of simulations are separated by: -------------------- | Data from different simulations within a set are separated by: --
