Why Blackspotted Stickleback?

How Behaviors Evolve Comparing closely related species can give insights into how behavior evolves.

Well studied: Three-spined Stickleback (Gasterosteus aculeatus)

  • Model organism for natural variation in behavioral evolution 1.
  • Divergence in parental care in two ecotypes1,2.
  • White and common ecotypes recently diverged 2.

Lesser studied: Blackspotted Stickleback (Gasterosteus wheatlandi)

  • Three-spined’s closest living relative.
  • Possible behavioral intermediate of commons & whites.
  • Blackspotted egg dispersal is similar to white three-spined 3.
