Abstract
In animals, genome size is correlated with many traits that also vary with latitude, such as body size and developmental rate. Crustaceans have highly variable genome sizes?ranging nearly 650-fold?and some polar crustaceans have exceptionally large genomes. Here we investigate whether genome size is positively correlated with latitude across 275 species of decapods, amphipods, and copepods. We also test whether this relationship is independent of other factors that covary with genome size and latitude?body size, habitat, and larval development?using phylogenetic generalized least squares methods and model selection using Akaike?s Information Criterion. In amphipods, all well-supported models explaining genome size included latitude, whereas in copepods supported models included body size, but not latitude. In decapods, there was a significant correlation between genome size and number of larval stages; however, model testing indicated that no single factor was most well-supported in explaining genome size correlations. While genome size generally increases with latitude across crustaceans, it is clearly a complex trait that differs among taxonomic groups.
