Evidence for Countergradient Growth Adaptation and Jordan's Rule in a Southern Hemisphere Fish, the Atherinopsid <i>Odontesthes regia</i>. [PDF]

open access: yesEcol Evol
We performed common garden experiments on offspring of the sea silverside Odontesthes regia to characterize thermal growth reaction norms of different populations along the Chilean coast. This showed that the species exhibits local adaptation in the form of countergradient growth adaptation because higher‐latitude southern populations grew faster at ...
