Mictocaris Halope
''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 w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Australian Museum
The Australian Museum is a heritage-listed museum at 1 William Street, Sydney central business district, New South Wales, Australia. It is the oldest museum in Australia,Design 5, 2016, p.1 and the fifth oldest natural history museum in the world, with an international reputation in the fields of natural history and anthropology. It was first conceived and developed along the contemporary European model of an encyclopedic warehouse of cultural and natural history and features collections of vertebrate and invertebrate zoology, as well as mineralogy, palaeontology and anthropology. Apart from exhibitions, the museum is also involved in Indigenous studies research and community programs. In the museum's early years, collecting was its main priority, and specimens were commonly traded with British and other European institutions. The scientific stature of the museum was established under the curatorship of Gerard Krefft, himself a published scientist. The museum is located at ...

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 ...
