Sideroxylon Cochranei
''Sideroxylon'' is a genus of trees in the family Sapotaceae described as a genus by Linnaeus in 1753. They are collectively known as bully trees. The generic name is derived from the Greek words σιδηρος (''sideros''), meaning "iron", and ξύλον (''xylon''), meaning "wood." Distribution The genus is distributed mainly in North and South America as well as in Africa, Madagascar, southern Asia, and various oceanic islands. Some species, such as gum bully ('' S. lanuginosum''), '' S. tenax'', and buckthorn bully ('' S. lycioides''), are found in subtropical areas of North America. The only South African species, the white milkwood ('' S. inerme''), is associated with three historical sites, and these individuals were declared national monuments due to their unusual longevity. Ecology Several species have become rare due to logging and other forms of habitat destruction. The tambalacoque ('' S. grandiflorum'') of Mauritius was affected by the extinction of the birds which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sideroxylon Lanuginosum
''Sideroxylon lanuginosum'' is a shrub or small tree of the family Sapotaceae. It is native to the Sun Belt and Midwest of the United States as well as Northeastern Mexico.

Coextinction
Coextinction and cothreatened refer to the phenomenon of the loss or decline of a host species resulting in the loss or endangerment of another species that depends on it, potentially leading to cascading effects across trophic levels. The term was originated by the authors Stork and Lyal (1993) and was originally used to explain the extinction of parasitic insects following the loss of their specific hosts. The term is now used to describe the loss of any interacting species, including competition with their counterpart, and specialist herbivores with their food source. Coextinction is especially common when a keystone species goes extinct. Causes The most frequently cited example is that of the extinct passenger pigeon and its parasitic bird lice '' Columbicola extinctus'' and ''Campanulotes defectus''. Recently, ''C. extinctus'' was rediscovered on the band-tailed pigeon, and ''C. defectus'' was found to be a likely case of misidentification of the existing '' Campanulotes ...

Dodo
The dodo (''Raphus cucullatus'') is an extinction, extinct flightless bird that was endemism, endemic to the island of Mauritius, which is east of Madagascar in the Indian Ocean. The dodo's closest relative was the also-extinct and flightless Rodrigues solitaire. The two formed the taxonomic rank, subtribe Raphina, a clade of extinct flightless birds that are a part of the group that includes Columbidae, pigeons and doves (the family Columbidae). The closest extant taxon, living relative of the dodo is the Nicobar pigeon. A white dodo was once thought to have existed on the nearby island of Réunion, but it is now believed that this assumption was merely confusion based on the also-extinct Réunion ibis and paintings of white dodos. Subfossil remains show the dodo measured about in height and may have weighed in the wild. The dodo's appearance in life is evidenced only by drawings, paintings, and written accounts from the 17th century. Since these portraits vary considerabl ...

Bird
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinction
Extinction is the termination of an organism by the death of its Endling, last member. A taxon may become Functional extinction, functionally extinct before the death of its last member if it loses the capacity to Reproduction, reproduce and recover. As a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include Dinosaur, non-avian dinosaurs, Machairodontinae, saber-toothed cats, and mammoths. Through evolution, species arise through the process of specia ...

Mauritius
Mauritius, officially the Republic of Mauritius, is an island country in the Indian Ocean, about off the southeastern coast of East Africa, east of Madagascar. It includes the main island (also called Mauritius), as well as Rodrigues, Agaléga, and St. Brandon (Cargados Carajos shoals). The islands of Mauritius and Rodrigues, along with nearby Réunion (a French overseas department), are part of the Mascarene Islands. The main island of Mauritius, where the population is concentrated, hosts the capital and largest city, Port Louis. The country spans and has an exclusive economic zone covering approximately . The 1502 Portuguese Cantino planisphere has led some historians to speculate that Arab sailors were the first to discover the uninhabited island around 975, naming it ''Dina Arobi''. Called ''Ilha do Cirne'' or ''Ilha do Cerne'' on early Portuguese maps, the island was visited by Portuguese sailors in 1507. A Dutch fleet, under the command of Admiral Van War ...

Sideroxylon Grandiflorum
''Sideroxylon grandiflorum'', also known as the tambalacoque or dodo tree, is a long-lived species of tree in the sapote family Sapotaceae. It is endemic to Mauritius. Description The fruit of ''Sideroxylon grandiflorum'' is analogous to a peach. Each is termed a drupe because each has a hard endocarp, or pit, surrounding the seed. The plant itself superficially resembles the unrelated '' Plumeria'', but the dodo tree's flowers and fruit are cauliflorous. Ecology In 1973, it was argued that the species was becoming extinct. There were supposedly only 13 specimens left, all estimated to be about 300 years old; the true age could not be determined because tambalacoque has no growth rings. Stanley Temple hypothesized that the dodo, which became extinct in the 17th century, ate tambalacoque fruits, and that only after passing through the digestive tract of the dodo could the seeds germinate. Temple force-fed seventeen tambalacoque fruits to wild turkeys in 1977. Seven of the fru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Destruction
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduction of invasive species, ecosystem nutrient depletion, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as the ...
