Moina is a genus of crustaceans within the family Moinidae. [3] [4] The genus was first described by W. Baird in 1850. They are referred to as water fleas, but are related to the much larger Daphnia magna and the larger Daphnia pulex . [5] This genus demonstrates the ability to survive in waters containing low oxygen levels, high salinity, and other impurities, including salt pans, and commonly eutrophication. [6] An example of such an extreme habitat is the highly saline Makgadikgadi Pans of Botswana, which supports prolific numbers of Moina belli . [7]
The Moina are known to be found in various types of bodies of water in Eurasia where new found research indicates that there is an increased presence of biodiversity in regions of Northern Eurasia, Japan and China. [8] According to genetic data, whole the genus Moina is divided into two big faunistic groups: European-Western Siberian and Eastern Siberian-Far Eastern, with a transitional zone at the Yenisey River basin (Eastern Siberia). [9] There is an increase of new phylogroups found in Northern Eurasia, an increase of 4 new Moina species in Japan and an increase of five new lineages in China. [9] [10] In the water bodies of the world, at least 4 species of Moina are non-native species. [11]
Moina contains these species: [3] [1]
Branchiopoda is a class of crustaceans. It comprises fairy shrimp, clam shrimp, Diplostraca, Notostraca and the Devonian Lepidocaris. They are mostly small, freshwater animals that feed on plankton and detritus.
Daphnia is a genus of small planktonic crustaceans, 0.2–6.0 mm (0.01–0.24 in) in length. Daphnia are members of the order Anomopoda, and are one of the several small aquatic crustaceans commonly called water fleas because their saltatory swimming style resembles the movements of fleas. Daphnia spp. live in various aquatic environments ranging from acidic swamps to freshwater lakes and ponds.
Clam shrimp are a group of bivalved branchiopod crustaceans that resemble the unrelated bivalved molluscs. They are extant and also known from the fossil record, from at least the Devonian period and perhaps before. They were originally classified in the former order Conchostraca, which later proved to be paraphyletic, due to the fact that water fleas are nested within clam shrimps. Clam shrimp are now divided into three orders, Cyclestherida, Laevicaudata, and Spinicaudata, in addition to the fossil family Leaiidae.
Hydrobiology is the science of life and life processes in water. Much of modern hydrobiology can be viewed as a sub-discipline of ecology but the sphere of hydrobiology includes taxonomy, economic and industrial biology, morphology, and physiology. The one distinguishing aspect is that all fields relate to aquatic organisms. Most work is related to limnology and can be divided into lotic system ecology and lentic system ecology.
Daphnia occidentalis is a species of crustacean in the family Daphniidae. It is endemic to Australia, and is the only species in the subgenus Australodaphnia.
Streptocephalus is a genus of fairy shrimp found in temporary waters in Africa, Australia, Eurasia, and Central and North America, following its ancient origin in Gondwana. It contains the following species:
Bosmina is a genus in the order Cladocera, the water fleas. Its members can be distinguished from those of Bosminopsis by the separation of the antennae; in Bosminopsis, the antennae are fused at their bases.
The Diplostraca or Cladocera, commonly known as water fleas, is a superorder of small, mostly freshwater crustaceans, most of which feed on microscopic chunks of organic matter, though some forms are predatory.
Daphniidae is a family of water fleas in the order Anomopoda.
Ephippia are winter or dry-season eggs of the various species of small crustacean in the order Cladocera ; they are provided with an extra shell layer, which preserves and protects the resting stages inside from harsh environmental conditions until the more favorable times, such as spring, when the reproductive cycle is able to take place once again. Ephippia are part of the back of a mother carrying them until they are fully developed. After molting, the ephippium stays in the water, or in the soil of dried puddles, small ponds, and vernal pools. The resting stages are often called eggs, but are in fact embryos with arrested development. Ephippia can rest for many years before the embryo resumes development upon an appropriate hatching stimulus.
Daphnia commutata is a species of water flea.
Daphnia is one of the three subgenera of the genus Daphnia, the others being Australodaphnia and Ctenodaphnia.
The wildlife of Korea belongs to the Palearctic realm. Native or endemic species of the Korean Peninsula include Korean hare, Korean water deer, Korean field mouse, Korean brown frog, Korean pine and Korean spruce. The Korean Demilitarized Zone (DMZ) with its forest and natural wetlands is a unique biodiversity spot, which harbours 82 endangered species such as the red-crowned crane, Amur leopard and the Siberian tiger. Overall, DMZ is home to about 70 mammalian species, more than 300 birds and about 3,000 plants.
Daphnia longispina is a planktonic crustacean of the family Daphniidae, a cladoceran freshwater water flea. It is native to Eurasia. D. longispina is similar in size and sometimes confused with the often sympatric D. pulex, but much smaller than D. magna. D. longispina is found in a wide range of standing freshwater bodies from small, ephemeral rock-pools to large lakes.
Sididae is a family of ctenopods in the order Diplostraca. There are about 6 genera and at least 20 described species in Sididae. Some Sididae are non-native species.
Podonidae is a family of onychopods in the order Diplostraca. There are about 8 genera and at least 20 described species in Podonidae. A lot of them are non-native species, many of which pose a great threat to aquatic ecosystems.
Chydoridae is a family of water fleas in the order Anomopoda. There are more than 50 genera and 520 described species in Chydoridae. A lot of Chydoridae species are non-native species, many of which pose a great threat to aquatic ecosystems.
Diaphanosoma is a genus of Sididae.
Cercopagididae is a family of crustaceans belonging to the order Diplostraca. A lot of Cercopagididae species are non-native species, many of which pose a great threat to aquatic ecosystems.
