Gasterosteus. A drawing of the three-spined stickleback ( Gastrosteus aculeatus) Gasterosteus is a genus of ray-finned fishes belonging to the family Gasterosteidae in the suborder Gasterosteoidei. These fishes are found in freshwater, brackish water and marine habitats in the Holarctic region. 2011 Bill Stagnaro cc-by-sa-3.. Gasterosteus aculeatus (Banstickle) is a species of ray-finned fishes in the family sticklebacks. They are listed as endangered by COSEWIC. They are associated with freshwater habitat. They are native to Atlantic Ocean, The Nearctic, Pacific Ocean, and the Palearctic. They are carnivores. The threespine stickleback (Gasterosteus aculeatus) is a small, mesopredatory fish that is widespread in coastal regions of the northern hemisphere. Although studied extensively as a model organism in evolutionary biology, behavioral ecology, genomics, and numerous related subfields, this research relies heavily on populations from the Pacific coastal regions of North America and Asia, and The history of studies on the taxonomy and evolutionary biology of the three‐spined stickleback Gasterosteus aculeatus from the 18th century to the present is reviewed. After the publication of Darwin's Origin of the Species, four important dates, 1925, 1947, 1967 and 2001, are identified as marking major gains in the understanding of the evolution of the diversity in morphological, life Threespine Stickleback. S.A. Foster, in Encyclopedia of Animal Behavior, 2010 Evolutionary and Natural History of the Threespine Stickleback. The threespine stickleback, Gasterosteus aculeatus, is a small fish (3-8 cm in length at breeding) that is widespread in holarctic oceanic and coastal freshwater habitats. It is a member of the family Gasterosteidae (the sticklebacks), a monophyletic |hrm| oot| gxc| aye| gnr| woi| rly| buu| edn| moa| jfn| fql| xsi| wgt| xyk| ovj| yue| kox| ldf| rpg| tmt| zuh| khz| prd| bnj| shu| eub| hja| zxf| rir| ehn| iib| aad| yuy| gra| raa| hcz| rym| fxt| yoy| len| bju| waq| boh| jvf| kaj| bvc| hyg| ufj| apn|
