Cuban Parakeet
The Cuban parakeet (''Psittacara euops'') is a species of parrot in the family Psittacidae that is endemic to the island of Cuba. It was Local extinction, extirpated from the Isla de la Juventud south of Cuba soon after 1900. Its natural habitats are Cuban dry forests, dry forests, Cuban cactus scrub, dry savanna, and arable land. The species breeds seasonally, nesting from April to July. It nests in holes in trees or termite nests, particularly those created by the Cuban green woodpecker. Three to five eggs are incubated for around 22 days, and the nestling period is between 45 and 50 days. The species was once very common but is now much reduced due to habitat loss and trapping for the cagebird trade. As a consequence it is now listed as Vulnerable species, vulnerable by the IUCN.

Johann Georg Wagler
Johann Georg Wagler (28 March 1800 – 23 August 1832) was a German herpetologist and ornithologist. Wagler was assistant to Johann Baptist von Spix, and gave lectures in zoology at the Ludwig Maximilian University of Munich after it was moved to Munich. He worked on the extensive collections brought back from Brazil by Spix, and published partly together with him books on reptiles from Brazil. Wagler wrote ''Monographia Psittacorum'' (1832), which included the correct naming of the blue macaws. In 1832, Wagler died of an accidental self-inflicted gunshot wound while out collecting in München-Moosach. Life Johann Georg Wagler was a German naturalist and scientist in the 19th century, whose works primarily focused on herpetology and ornithology (Beolens, Watkins & Grayson, 2011). Johan Georg Wagler was born on the 28th of March 1800, in the city of Nuremberg, where the Chancellor of the City Court was Wagler's father (Wagler, 1884). After taking up gymnastics at Nuremberg, J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Termite
Termites are small insects that live in colonies and have distinct castes (eusocial) and feed on wood or other dead plant matter. Termites comprise the infraorder Isoptera, or alternatively the epifamily Termitoidae, within the order Blattodea (along with cockroaches). Termites were once classified in a separate order from cockroaches, but recent phylogenetic studies indicate that they evolved from cockroaches, as they are deeply nested within the group, and the sister group to wood eating cockroaches of the genus ''Cryptocercus''. Previous estimates suggested the divergence took place during the Jurassic or Triassic. More recent estimates suggest that they have an origin during the Late Jurassic, with the first fossil records in the Early Cretaceous. About 3,106 species are currently described, with a few hundred more left to be described. Although these insects are often called "white ants", they are not ants, and are not closely related to ants. Like ants and some bees a ...

Birds Described In 1832
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have 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 loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Birds Of Cuba
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psittacara
''Psittacara'' is a genus of parakeets in the tribe Arini. Species of the genus are found in Central and South America, the Caribbean and one species reaching the southern United States. Until 2013, all the species were placed in the genus ''Aratinga''. Many of the ''Psittacara'' species are kept in aviculture or as companion parrots, where they are commonly known as conures. Taxonomy The members of this genus were formerly placed in the genus ''Aratinga''. Molecular phylogenetic studies had found that ''Aratinga'' was non-monophyletic so in order to create monophylectic genera James Van Remsen Jr. and collaborators proposed in 2013 that ''Aratinga'' should be split and a group of species moved to the resurrected genus ''Psittacara''. The genus had been introduced in 1825 by the Irish zoologist Nicholas Aylward Vigors with the white-eyed parakeet as the type species. Species The genus contains 13 species including one which is now extinct: * Green parakeet (''Psittacara holoc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...

Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Cuban Green Woodpecker
The Cuban green woodpecker (''Xiphidiopicus percussus'') is a species of woodpecker in the family Picidae and tribe Melanerpini, known locally in Cuban Spanish as carpintero verde (literally "green woodpecker"). It is the only species within the genus ''Xiphidiopicus'' and is one of two woodpeckers endemic to Cuba. It is the most widespread and common woodpecker in Cuba, inhabiting primarily woodlands, as well as dry and wet forests, pine forests and mangroves. The population of the Cuban green woodpecker is stable and its status is listed as "Least Concern". Appearance A medium-sized and colorful bird, the Cuban green woodpecker is similar to a sapsucker in general shape and size. Featuring olive green overparts and yellow, streaked underparts, the Cuban green woodpecker usually appears crested, and features a bright red upper breast, as well as a black chin contrasting a white face and supercilium. In males, a red crown is present, while females possess black crowns with whit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arable Land
Arable land (from the la, arabilis, "able to be ploughed") is any land capable of being ploughed and used to grow crops.''Oxford English Dictionary'', "arable, ''adj''. and ''n.''" Oxford University Press (Oxford), 2013. Alternatively, for the purposes of agricultural statistics, the term often has a more precise definition: A more concise definition appearing in the Eurostat glossary similarly refers to actual rather than potential uses: "land worked (ploughed or tilled) regularly, generally under a system of crop rotation". In Britain, arable land has traditionally been contrasted with pasturable land such as heaths, which could be used for sheep-rearing but not as farmland. Arable land area According to the Food and Agriculture Organization of the United Nations, in 2013, the world's arable land amounted to 1.407 billion hectares, out of a total of 4.924 billion hectares of land used for agriculture.

Parrot
Parrots, also known as psittacines (), are birds of the roughly 398 species in 92 genera comprising the order Psittaciformes (), found mostly in tropical and subtropical regions. The order is subdivided into three superfamilies: the Psittacoidea ("true" parrots), the Cacatuoidea (cockatoos), and the Strigopoidea (New Zealand parrots). One-third of all parrot species are threatened by extinction, with higher aggregate extinction risk ( IUCN Red List Index) than any other comparable bird group. Parrots have a generally pantropical distribution with several species inhabiting temperate regions in the Southern Hemisphere, as well. The greatest diversity of parrots is in South America and Australasia. Characteristic features of parrots include a strong, curved bill, an upright stance, strong legs, and clawed zygodactyl feet. Many parrots are vividly coloured, and some are multi-coloured. Most parrots exhibit little or no sexual dimorphism in the visual spectrum. They form the most ...

Cuban Cactus Scrub
The Cuban cactus scrub is a xeric shrubland ecoregion that occupies on the leeward coast of Cuba. Most of it occurs in the southeastern part of the island in the provinces of Guantánamo and Santiago de Cuba. The ecoregion receives less than of rainfall annually. The principal soils are coastal rendzinas that were derived from coralline limestone. Cuban cactus scrub contains four vegetation zones: xerophytic coastal and subcoastal scrubland, coastal thorny semidesert, coastal sclerophyllous scrubland, and rocky coastal scrublands. Xerophytic coastal and subcoastal scrubland Vegetation in the xerophytic coastal and subcoastal scrublands reaches a height of and is dominated by palms and succulents, especially cacti. Common evergreen plants include (''Bourreria virgata''), ('' Capparis cynophallophora''), ('' Eugenia foetida''), ''Bursera glauca'', '' B. cubana'', '' Croton'' spp., ''Cordia'' spp., ''Calliandra colletioides'', ''Caesalpinia'' spp., ''Acacia'' spp., '' P ...
