Variation in continuous reaction norms: quantifying directions of biological interest.

The American naturalist - 1 Aug 2005

Izem Rima, Kingsolver Joel G

Abstract excerpt

Thermal performance curves are an example of continuous reaction norm curves of common shape. Three modes of variation in these curves--vertical shift, horizontal shift, and generalist-specialist trade-offs--are of special interest to evolutionary biologists. Since two of these modes are nonlinear, traditional methods such as principal components analysis fail to decompose the variation into biological modes and...
