In ectotherms, lower temperatures in high-latitude environments would theoretically reduce
the annual growth rates of individuals. If slower growth and resultant smaller body size
reduce fitness, individuals in higher latitudes may evolve compensatory responses. Two
alternative models of such latitudinal compensation are possible: Model I: thermal reaction
norms for growth rates of high-latitude individuals may be horizontally shifted to a lower
range of temperatures, or Model II: reaction norms may be vertically shifted so that high …
