Table 3 Results from stepwise logistic regressions relating the presence and absence of each marker to the two first axes of the principal component analysis (PCA)1, the host-plant (HP), and the three interactions2.

From: Genome scan to assess the respective role of host-plant and environmental constraints on the adaptation of a widespread insect

  1. 1 Axis 1 and axis 2 are the two first PCA components (representing respectively 76 and 20% of total inertia) of the projection of altitude and nine climatic variables calculated from the latitude/longitude as yearly mean of monthly values for the period 1961 to 2001 (see Methods for more details).
  2. 2Statistically significant logistic regression coefficients are indicated in bold (p-values for each coefficient are given in parenthesis). NS: the correlation was not significant.
