Effects of dietary differentiation and geographic distance on genetic differentiation of Eastern European wolves.

<p>Marginal and conditional tests of individual variable sets as well as sequential tests of the forward selection procedure are reported (see Methods for the description of the tests). “Pseudo-F” indicates test statistics, <i>P</i> probability values and “%var” the percentage of the genetic variation explained by the particular variable. In the case of sequential tests, “%var” indicates the percentage of the genetic variation explained by a cumulative effect of variables. The top-down sequence of variables corresponds to the sequence that was indicated by the forward selection procedure. The variable set “coordinates” included latitude and longitude, and “stable isotope composition” included <i>δ</i>¹⁵N and <i>δ</i>¹³C values. Genetic distances were calculated based on the data on variability at 14 microsatellite loci obtained in an earlier study <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0039341#pone.0039341-Pilot1" target="_blank">[7]</a>.
