Three-spined stickleback research has been central to the field of eco-evolutionary dynamics. [ 52 ] [ 53 ] Eco-evolutionary dynamics is an area of study investigating how ecological processes (e.g., population dynamics , community interactions , and nutrient cycling ) affect how populations evolve, and in turn, how these patterns of evolution ...
A three-spined stickleback like those used in Tinbergen's experiments. One example of fixed action patterns is the courtship and aggression behaviours of the male stickleback, particularly the three-spined stickleback, during mating season, described in a series of studies by Niko Tinbergen.

The maximum size of the best-known species, the three-spined stickleback (Gasterosteus aculeatus), is about 4 inches, but few of them are more than 3 inches long. They mature sexually at a length of about 2 inches. [11] Most other stickleback species are roughly similar in size or somewhat smaller.

The smallhead stickleback (Gasterosteus microcephalus), or resident threespined stickleback, is a fish species, which widespread in the basin of the Pacific Ocean: Japan, also Mexico. Freshwater demersal fish, up to 5.5 cm (2.2 in) length. Habits small streams, where feeds on aquatic insects and other invertebrates. [1]
Three-spined stickleback fish have been a frequently studied species in ecological speciation.. Ecological speciation is a form of speciation arising from reproductive isolation that occurs due to an ecological factor that reduces or eliminates gene flow between two populations of a species.
