Gasterosteus
''Gasterosteus'' is a genus of ray-finned fishes belonging to the Family (biology), family Gasterosteidae, the sticklebacks. These fishes are found in freshwater, brackish water and marine habitats in the Holarctic realm, Holarctic region.

Gasterosteus Aculeatus
The three-spined stickleback (''Gasterosteus aculeatus'') is a fish native to most inland and coastal waters north of 30°N. It has long been a subject of scientific study for many reasons. It shows great morphological variation throughout its range, ideal for questions about evolution and population genetics. Many populations are anadromous (they live in seawater but breed in fresh or brackish water) and very tolerant of changes in salinity, a subject of interest to physiologists. It displays elaborate breeding behavior (defending a territory, building a nest, taking care of the eggs and fry) and it can be social (living in shoals outside the breeding season) making it a popular subject of inquiry in fish ethology and behavioral ecology. Its antipredator adaptations, host-parasite interactions, sensory physiology, reproductive physiology, and endocrinology have also been much studied. Facilitating these studies is the fact that the three-spined stickleback is easy to find in natur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gasterosteus Islandicus
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'', though several authorities offer it full species status. It was first described by French biologist Henri Émile Sauvage in 1874. Distribution The Icelandic threespine stickleback is known from at least four different lakes in Iceland, including Þingvallavatn, Hreðavatn, Frostastaðavatn, and Mývatn Mývatn () is a shallow lake situated in an area of active volcanism in the north of Iceland, near Krafla volcano. It has a high amount of biological activity. The lake and the surrounding wetlands provides a habitat for a number of waterbirds, .... Description The species is differentiated from other sticklebacks by having a deep notch on the anterior margin of the pelvic girdle. As opposed to other members of the genus, the Icelandic threespine stickleb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gasterosteus Nipponicus
''Gasterosteus nipponicus'' is a species of ray-finned fish belonging to the Family (biology), family Gasterosteidae, the sticklebacks. This species is found in the northwestern Pacific Ocean. Taxonomy ''Gasterosteus nipponicus'' first formally Species description, described in 2014 by Masahito Higuchi, Harumi Sakai and Akira Goto with the Type locality (biology), type locality given Usujiri, Minamikayabe, Hokkaido in Japan. Higachi and Goto had previously identified a lineage of three-spined sticklebacks (''G. aculateus'') from Japan which had substantial differences from the other lineages, both morphological and genetic, and which genetic studies showed rarely hybridised with sympatric populations of threes-spined sticklebacks. Description ''Gasterosteus nipponicus'' differs from the three-spined stickleback in that the lateral plates are complete and that they suddenly reduce in size over the anus, the depth of lateral plate over the anus less than 60% of the depth of the de ...

Gasterosteus Doryssus
''Gasterosteus doryssus'' is an extinct species of freshwater stickleback fish that inhabited inland freshwater habitats of the North American Great Basin during the Miocene. It is known from thousands of articulated fossil skeletons, comprising various age classes and two different ecomorphs, discovered in diatomite deposits of the Truckee Formation near Hazen, Nevada. ''G. doryssus'' inhabited Lake Truckee, a predecessor to Lake Lahontan. Lake Truckee was subject to seasonal diatom blooms that would settle to the lake bottom to form diatomite, fossilizing any other animals that died during the season. This seasonal diatomite deposition provides an exquisite record of the annual dynamics of this ecosystem over several millennia, including a time series of the evolution of ''G. doryssus'' over 100,000 years and the eco-evolutionary dynamics that drove it. The time series of ''G. doryssus'' fossils has been used to provide evidence for and against specific evolutionary models, ...

Gasterosteus Crenobiontus
The Techirghiol stickleback (''Gasterosteus crenobiontus'') was an endemic fish species, found in the streams inflowing to the coastal hypersaline Lake Techirghiol in southern Romania. It was a freshwater benthopelagic fish, up to SL in length. It is considered extinct due to hybridization with the three-spined stickleback The three-spined stickleback (''Gasterosteus aculeatus'') is a fish native to most inland and coastal waters north of 30°N. It has long been a subject of scientific study for many reasons.

Gasterosteus Wheatlandi
The blackspotted stickleback (''Gasterosteus wheatlandi'') is species of ray-finned fish belonging to the family Gasterosteidae, the sticklebacks. This fish is found in the western Atlantic from the coasts of Newfoundland (Canada) to Massachusetts (United States). This is a benthopelagic species of marine and brackish waters, rarely entering freshwater, which remains near the shore. It is frequently associated with floating vegetation. The male builds a nest, in which the females deposit eggs and the male guards and aerates them. It is a small fish which reaches a maximum published total length of , although is more typical. The specific name honors Richard H. Wheatland who was the Cabinet Keeper (and collector of fishes and reptiles), for the Essex County Natural History Society of Salem, Massachusetts and who collected type Type may refer to: Science and technology Computing * Typing, producing text via a keyboard, typewriter, etc. * Data type, collection of values used fo ...

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called '' lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they dominate the subphylum Vertebrata, and constitute nearly 99% of the over 30,000 extant ...

10th Edition Of Systema Naturae
The 10th edition of ''Systema Naturae'' (Latin; the English title is ''A General System of Nature'') is a book written by Swedish naturalist Carl Linnaeus and published in two volumes in 1758 and 1759, which marks the starting point of zoological nomenclature. In it, Linnaeus introduced binomial nomenclature for animals, something he had already done for plants in his 1753 publication of ''Species Plantarum''. Starting point Before 1758, most biological catalogues had used polynomial names for the taxa included, including earlier editions of ''Systema Naturae''. The first work to consistently apply binomial nomenclature across the animal kingdom was the 10th edition of ''Systema Naturae''. The International Commission on Zoological Nomenclature therefore chose 1 January 1758 as the "starting point" for zoological nomenclature and asserted that the 10th edition of ''Systema Naturae'' was to be treated as if published on that date. Names published before that date are unavailable, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
