Sideroxylon Socorrense
''Sideroxylon socorrense'' is a plant species in the family Sapotaceae. It is endemic to Mexico, occurring only on Socorro in the Revillagigedo Islands. On its island home, this small tree grows in habitat that is at least seasonally humid. This restricts it mainly to a belt of woodland between 650 and 900 m above mean sea level, except on the northern side where wetter conditions predominate. It is classified as Vulnerable by the IUCN due to the adverse effects of introduced sheep grazing and the twice-yearly swarming of the locust ''Schistocerca piceifrons'', a non-native pest that has become established on Socorro more recently. The fruits of this plant are among the favorite foods of the nearly-extinct Socorro mockingbird (''Mimus graysoni'') and the Socorro dove (''Zenaida graysoni'') which presently only survives in captivity.BLI (2007b) Similar as in other ''Sideroxylon ''Sideroxylon'' is a genus of trees in the family Sapotaceae described as a genus by Linnaeus in ...

Plant
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ...

Sheep
Sheep or domestic sheep (''Ovis aries'') are domesticated, ruminant mammals typically kept as livestock. Although the term ''sheep'' can apply to other species in the genus ''Ovis'', in everyday usage it almost always refers to domesticated sheep. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female is referred to as a ''ewe'' (), an intact male as a ''ram'', occasionally a ''tup'', a castrated male as a ''wether'', and a young sheep as a ''lamb''. Sheep are most likely descended from the wild mouflon of Europe and Asia, with Iran being a geographic envelope of the domestication center. One of the earliest animals to be domesticated for agricultural purposes, sheep are raised for fleeces, meat (lamb, hogget or mutton) and milk. A sheep's wool is the most widely used animal fiber, and is usually harvested by shearing. In Commonw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trees Of Mexican Pacific Islands
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endemic Flora Of Mexico
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Condor (journal)
''Ornithological Applications'', formerly ''The Condor'' and ''The Condor: Ornithological Applications'', is a peer-reviewed quarterly scientific journal covering ornithology. It is an official journal of the American Ornithological Society. History The journal was first published in 1899 as the ''Bulletin of the Cooper Ornithological Club'' by a group of biologists in California. The journal's scope was regional, covering the western United States. In 1900, the name was changed to ''The Condor''. In 1947, the journal's subtitle was shortened to ''The Condor, Journal of the Cooper Ornithological Club''. Editors-in-Chief: 1899-1902: Chester Barlow; 1902-1905: Walter K.

Sideroxylon
''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, but also 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'', syn. ''Calvaria major'') of Mauritius was affected by the exti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Socorro Mockingbird
The Socorro mockingbird (''Mimus graysoni'') is an endangered mockingbird endemic to Socorro Island in Mexico's Revillagigedo Islands. The specific epithet commemorates the American ornithologist Andrew Jackson Grayson. ''Mimus graysoni'' shows its close relationship to the northern and tropical mockingbirds rather subtly. It is a much stouter bird, resembling some thrashers in habitus. It also has a distinct juvenile plumage, more rufous above and has a heavy pattern, especially below. This uncannily resembles, e.g., the gray thrasher (''Toxostoma cinereum'') from Baja California, but is apparently a case of convergent evolution. Systematics and taxonomy This is a rather distinct ''Mimus'' mockingbird and was for some time placed into a distinct genus, ''Mimodes''. This was revealed to be incorrect based on analysis of mtDNA NADH dehydrogenase subunit 2 sequences. Rather, the present species is closely related to the northern and tropical mockingbirds. Its distinctiveness ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pest (organism)
A pest is any animal or plant harmful to humans or human concerns. The term is particularly used for creatures that damage crops, livestock, and forestry or cause a nuisance to people, especially in their homes. Humans have modified the environment for their own purposes and are intolerant of other creatures occupying the same space when their activities impact adversely on human objectives. Thus, an elephant is unobjectionable in its natural habitat but a pest when it tramples crops. Some animals are disliked because they bite or sting; snake Snakes are elongated, Limbless vertebrate, limbless, carnivore, carnivorous reptiles of the suborder Serpentes . Like all other Squamata, squamates, snakes are ectothermic, amniote vertebrates covered in overlapping Scale (zoology), scales. Ma ...s, wasps, ants, bed bugs, fleas and ticks belong in this category. Others enter the home; these include houseflies, which land on and contaminate food, beetles, which tunnel into the woodwor ...

Schistocerca Piceifrons
''Schistocerca piceifrons'' is a large locust in the subfamily Cyrtacanthacridinae: Acrididae. There are two subspecies. ''S. p. piceifrons'' is sometimes called the Central American Locust and ''S. p. peruviana'' is sometimes known as the Peruvian Locust. Taxonomy and Distribution ''S. piceifrons'' is closely related to ''Schistocerca americana'', but exhibits a greater degree of phase polymorphism referred to in the technical literature as "density-dependent phenotypic plasticity. It is the swarming locust Locusts (derived from the Vulgar Latin ''locusta'', meaning grasshopper) are various species of short-horned grasshoppers in the family Acrididae that have a swarming phase.
