metadata.value: Sexual dimorphism (SD) in the threespine stickleback Gasterosteus aculeatus reflects
  the different roles of the sexes in reproduction and their adaptations to
  different ecological niches. We quantified SD in one population of marine stickleback
  from the White Sea, collected during the spawning period from three
  spawning grounds, each at a distance of 5 km or less from the others. We used
  a landmark-based approach to quantify variation in 44 morphometric linear
  traits. In total, 749 females and 693 males were analyzed. In males, anterior
  body parts are larger — the base of the caudal fin and armor structures such
  as the first and second dorsal spines and the pelvic spine. Females have larger
  posterior bodies — the abdomen, pelvic girdle and the third dorsal spine. The
  SD of caudal body parts exhibits complex patterns. In White Sea threespine
  stickleback, SD patterns are generally similar to other populations of the species,
  but more often show male-biased patterns. Female-biased size SD may be
  associated with the female biased sex ratio of White Sea stickleback.
