Mictocaris
''Mictocaris halope'' is the only species of cave crustacean in the monotypic genus ''Mictocaris''. It is placed in its own family, Mictocarididae, and is sometimes considered the only member of the order Mictacea. ''Mictocaris'' is endemic to anchialine caves in Bermuda, and grows up to long. Its biology is poorly known. Taxonomy ''Mictocaris halope'' is the only species in the genus ''Mictocaris'', and in the family Mictocarididae. When the family Hirsutiidae is treated as the separate order Bochusacea, ''Mictocaris halope'' is the only species that remains in the order Mictacea. Description ''Mictocaris'' is long and is reflective. It is native to four anchialine limestone caves in Bermuda: it was first discovered by divers in Crystal Cave, and then further populations were found in Green Bay Cave (South Harrington Sound Passage and North Shore Passage), Roadside Cave and Tucker's Town Cave. Ecology ''Mictocaris'' is rarely encountered because it lives only in deep wate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mictacea
Mictacea is a monotypic order of crustaceans. It was originally erected for three species of small shrimp-like animals of the deep sea and anchialine caves. They were placed in two families, the Mictocarididae and Hirsutiidae, but Hirsutiidae is now placed in order Bochusacea, leaving Mictacea with a single species, ''Mictocaris halope''. Description Mictaceans have a brood pouch (marsupium) and biramous thoracic limbs, but lack a carapace. They have eyestalks but "no functioning visual elements". History The existence of animals resembling the Mictacea had been predicted by Frederick Schram in the early 1980s. Two groups of scientists independently discovered the animals in 1985, and, once they learnt of each other's work, agreed to work together on the paper describing the new order. Species A single species is recognised: ; Mictocarididae Bowman & Iliffe, 1985 *''Mictocaris halope ''Mictocaris halope'' is the only species of cave crustacean in the monotypic genus ...

Thomas Elliot Bowman III
Thomas Elliot Bowman III (October 21, 1918 – August 10, 1995) was an American carcinologist best known for his studies of isopods and copepods. Bowman was born and grew up in Brooklyn, New York (state), New York. He graduated from Kent School in Kent, Connecticut in 1937 and Harvard College in 1941. During the World War II, Second World War, he spent four years in the United States Army, U.S. Army, gaining a degree in veterinary medicine from the University of Pennsylvania. Afterwards, he went to the University of California, Berkeley, where he gained a master's degree, and then worked at the Scripps Institution of Oceanography, where he gained a Doctor of Philosophy, Ph.D. (awarded by the University of California, Los Angeles). During his career, Bowman wrote 163 papers, using a style which has been likened to that of Ernest Hemingway and Albert Camus. As well as describing 116 new species (including 55 isopods, 28 copepods, one suctorian and one Chaetognatha, chaetognath), 16 ge ...

Freshwater Crustaceans Of North America
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh wa ...

Malacostraca Genera
Malacostraca (from New Latin; ) is the largest of the six classes of crustaceans, containing about 40,000 living species, divided among 16 orders. Its members, the malacostracans, display a great diversity of body forms and include crabs, lobsters, crayfish, shrimp, krill, prawns, woodlice, amphipods, mantis shrimp, tongue-eating lice and many other less familiar animals. They are abundant in all marine environments and have colonised freshwater and terrestrial habitats. They are segmented animals, united by a common body plan comprising 20 body segments (rarely 21), and divided into a head, thorax, and abdomen. Etymology The name Malacostraca was coined by a French zoologist Pierre André Latreille in 1802. He was curator of the arthropod collection at the National Museum of Natural History in Paris. The name comes from the Greek roots (', meaning "soft") and (', meaning "shell"). The name is misleading, since the shell is soft only immediately after moulting, and is usuall ...

Population Fragmentation
Population fragmentation is a form of population segregation. It is often caused by habitat fragmentation. Causes of Fragmentation Fragmentation can be the cause of natural forces or human actions, although in modern times, human activity is the most common cause. Some general causes of fragmentation are: * the development of land around a protected area, even through the addition of a single road lane or fence line, * the captivity, capture or killing of species in an area that links populations, * the movement of a population away from other individuals of that species, such as the natural introduction of wolves and moose on Isle Royale, * geologic processes, such as landslides or volcanoes, dividing a habitat * rising sea levels separating islands from what was once a common landmass, * global warming, especially when coupled with mountains, reducing movement from one habitat to another. Genetic effects Population fragmentation causes inbreeding depression, which leads to a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zootaxa
''Zootaxa'' is a peer-reviewed scientific mega journal for animal taxonomists. It is published by Magnolia Press (Auckland, New Zealand). The journal was established by Zhi-Qiang Zhang in 2001 and new issues are published multiple times a week. From 2001 to 2020, more than 60,000 new species have been described in the journal accounting for around 25% of all new taxa indexed in The Zoological Record in the last few years. Print and online versions are available. Temporary suspension from JCR The journal exhibited high levels of self-citation and its journal impact factor of 2019 was suspended from ''Journal Citation Reports'' in 2020, a sanction which hit 34 journals in total. Biologist Ross Mounce noted that high levels of self-citation may be inevitable for a journal which publishes a large share of new species classification. Later that year this decision was reversed and it was admitted that levels of self-citation are appropriate considering the large proportion of papers f ...
