Three-spined stickleback research has been central to the field of eco-evolutionary dynamics. [ 51 ] [ 52 ] 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.
Prevalence — the proportion of host population infected — in naturally infected populations of the first intermediate hosts is likely low. [5] Conversely, in populations where Schistocephalus solidus infects the second intermediate host (three-spined stickleback) it can reach high prevalence, up to 93% in both European and North American populations [6] [7]
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]
The Icelandic threespine stickleback (Gasterosteus islandicus) is a freshwater fish, and one of the few vertebrate species endemic to Iceland. In some literature it is considered as a subspecies of G. aculeatus, [2] though several authorities offer it full species status. [3] [4] It was first described by French biologist Henri Émile Sauvage ...
