Assessing the origin of trait variation during evolutionary history is
an important first step in understanding evolutionary diversification.
Here, we tested the influence of shared ancestry and climate, and the
interplay of both, on the variation of ten life history traits in
Triturus newts. We showed that (1) climate alone has driven the
evolution of variation in live life history traits, (2) phylogenetic
signal partly explains the variation in two traits (vitellus diameter
and snout-vent length of larvae at metamorphosis), and (3) the interplay
of shared ancestry and climate explains the variation in one trait
(snout-vent length of larvae at metamorphosis). This study highlights
the coarse-grained influence of shared ancestry and climate on the
structure of phenotypic trait variation in Triturus and provides a
handle for more detailed, fine grained studies on the evolution of
phenotypic trait variation.
