Ptychochromis Insolitus
''Ptychochromis insolitus'', also known as the Mangarahara cichlid or joba mena, is a species of cichlid endemic to certain river systems in northern Madagascar.Stiassny, M., and Sparks, J. S. (2006). ''Phylogeny and Taxonomic Revision of the Endemic Malagasy Genus Ptychochromis (Teleostei: Cichlidae), with the Description of Five New Species and a Diagnosis for Katria, New Genus.'' American Museum Novitates 3535. This critically endangered fish is threatened by habitat loss and competition from introduced species; after the last-known female was killed during a breeding attempt, its conservation received significant international attention as London Zoo launched a media campaign to identify any remaining individuals. A remnant population was discovered by aquaculture entrepreneur Guy Tam Hyock in 2013, and breeding programs in Madagascar and at Toronto Zoo have resulted in thousands of successful hatchlings.

The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide sc ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Tilapia
Tilapia ( ) is the common name for nearly a hundred species of cichlid fish from the coelotilapine, coptodonine, heterotilapine, oreochromine, pelmatolapiine, and tilapiine tribes (formerly all were "Tilapiini"), with the economically most important species placed in the Coptodonini and Oreochromini. Tilapia are mainly freshwater fish inhabiting shallow streams, ponds, rivers, and lakes, and less commonly found living in brackish water. Historically, they have been of major importance in artisanal fishing in Africa, and they are of increasing importance in aquaculture and aquaponics. Tilapia can become a problematic invasive species in new warm-water habitats such as Australia, whether deliberately or accidentally introduced, but generally not in temperate climates due to their inability to survive in cold water. Tilapia has been the fourth-most consumed fish in the United States since 2002. The popularity of tilapia came about due to its low price, easy preparation, and ...

Hotelier
A hotel manager, hotelier, or lodging manager is a person who manages the operation of a hotel, motel, resort, or other lodging-related establishment. Management of a hotel operation includes, but is not limited to management of hotel staff, business management, upkeep and sanitary standards of hotel facilities, guest satisfaction and customer service, marketing management, sales management, revenue management, financial accounting, purchasing, and other functions. The title "hotel manager" or "hotelier" often refers to the hotel's General Manager who serves as a hotel's head executive, though their duties and responsibilities vary depending on the hotel's size, purpose, and expectations from ownership. The hotel's General Manager is often supported by subordinate department managers that are responsible for individual departments and key functions of the hotel operation. Hotel management structure The size and complexity of a hotel management organizational structure varies si ...

Life Expectancy
Life expectancy is a statistical measure of the average time an organism is expected to live, based on the year of its birth, current age, and other demographic factors like sex. The most commonly used measure is life expectancy at birth (LEB), which can be defined in two ways. ''Cohort'' LEB is the mean length of life of a birth cohort (all individuals born in a given year) and can be computed only for cohorts born so long ago that all their members have died. ''Period'' LEB is the mean length of life of a hypothetical cohort assumed to be exposed, from birth through death, to the mortality rates observed at a given year. National LEB figures reported by national agencies and international organizations for human populations are estimates of ''period'' LEB. In the Bronze Age and the Iron Age, human LEB was 26 years; in 2010, world LEB was 67.2 years. In recent years, LEB in Eswatini (formerly Swaziland) is 49, while LEB in Japan is 83.

Extinct In The Wild
A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as known only by living members kept in captivity or as a naturalized population outside its historic range due to massive habitat loss. Examples Examples of species and subspecies that are extinct in the wild include: *Alagoas curassow (last unconfirmed sighting reported in the late 1980s, listed extinct in the wild since 1994) *Beloribitsa * Cachorrito de charco palmal (last seen in 1994, listed extinct in the wild since 1996) * Christmas Island blue-tailed skink (listed extinct in the wild since 2014) *Dabry's sturgeon (listed extinct in the wild since 2022) * Escarpment cycad (listed extinct in the wild since 2006) *Franklinia (last seen in 1803, listed extinct in the wild since 1998) *Golden skiffia (listed extinct in the wild since 1996) *Guam kingfisher (listed extinct in the wild since 1986) *Hawaiian crow or ʻalalā (last seen in 2002, li ...

Territory (animal)
In ethology, territory is the sociographical area that an animal consistently defends against conspecific competition (or, occasionally, against animals of other species) using agonistic behaviors or (less commonly) real physical aggression. Animals that actively defend territories in this way are referred to as being territorial or displaying territorialism. Territoriality is only shown by a minority of species. More commonly, an individual or a group of animals occupies an area that it habitually uses but does not necessarily defend; this is called its home range. The home ranges of different groups of animals often overlap, and in these overlap areas the groups tend to avoid each other rather than seeking to confront and expel each other. Within the home range there may be a ''core area'' that no other individual group uses, but, again, this is as a result of avoidance. Function The ultimate function of animals inhabiting and defending a territory is to increase the indi ...

Zoological Society Of London
The Zoological Society of London (ZSL) is a charity devoted to the worldwide conservation of animals and their habitats. It was founded in 1826. Since 1828, it has maintained the London Zoo, and since 1931 Whipsnade Park. History On 29 November 1822, the birthday of John Ray, "the father of modern zoology", a meeting held in the Linnean Society in Soho Square led by Rev. William Kirby, resolved to form a "Zoological Club of the Linnean Society of London". Between 1816 and 1826, discussions between Stamford Raffles, Humphry Davy, Joseph Banks and others led to the idea that London should have an establishment similar to the Jardin des Plantes in Paris. It would house a zoological collection "which should interest and amuse the public." The society was founded in April 1826 by Sir Stamford Raffles, the Marquess of Lansdowne, Lord Auckland, Sir Humphry Davy, Robert Peel, Joseph Sabine, Nicholas Aylward Vigors along with various other nobility, clergy, and naturalists. ...

Species Reintroduction
Species reintroduction is the deliberate release of a species into the wild, from captivity or other areas where the organism is capable of survival. The goal of species reintroduction is to establish a healthy, genetically diverse, self-sustaining population to an area where it has been extirpated, or to augment an existing population. Species that may be eligible for reintroduction are typically threatened or endangered in the wild. However, reintroduction of a species can also be for pest control; for example, wolves being reintroduced to a wild area to curb an overpopulation of deer. Because reintroduction may involve returning native species to localities where they had been extirpated, some prefer the term "reestablishment". Humans have been reintroducing species for food and pest control for thousands of years. However, the practice of reintroducing for conservation is much younger, starting in the 20th century. Methods for sourcing individuals There are a variety of appro ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Sauvagella Robusta
''Sauvagella robusta'' is a small species of fish in the family Clupeidae. It is endemic to the Amboaboa and Mangarahara River Basins in northern Madagascar.Stiassny, M.L.J. (2002). ''Revision of Sauvagella Bertin (Clupeidae: Pellonulinae: Ehiravini) with a description of a new species from the freshwaters of Madagascar and diagnosis of Ehiravini.'' Copeia 2002(1): 67-76. This relatively slender fish reaches a length of , and is overall pale yellowish with silvery on the lower parts. Its current conservation status is unclear, but the cichlid ''Ptychochromis insolitus'', which is highly threatened from habitat loss, is native to the same region. ''Sauvagella robusta'' is known to survive at least in Lake Tseny A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much large ....IUCN, Freshwater Fis ...

Paretroplus Gymnopreopercularis
''Paretroplus gymnopreopercularis'' is a species of cichlid from the vicinity of the confluence of the Amboaboa and Mangarahara Rivers near Mandritsara in northern Madagascar.Sparks, J. S. (2008). ''Phylogeny of the Cichlid Subfamily Etroplinae and Taxonomic Revision of the Malagasy Cichlid Genus Paretroplus (Teleostei: Cichlidae).'' Bulletin of the American Museum of Natural History Number 314 :1–151 Until its official scientific description in 2008, it was temporarily known as the ''Paretroplus'' nov. sp. "sofia". It is endangered because of habitat degradation, overfishing and invasive species. Following the construction of a dam on the Mangarahara River, surveys have failed to relocate ''P. gymnopreopercularis'' in this river. This relatively elongate ''Paretroplus'' reaches about in length and is closely related to '' P. kieneri'', which it resembles. '' P. nourissati'' is found in the same region as ''P. gymnopreopercularis'', but the latter appears to be restricted to ...
