Atoll Fruit Dove
The atoll fruit dove (''Ptilinopus coralensis'') is a species of bird in the family Columbidae. It is endemic to the Tuamotu archipelago in French Polynesia. Its natural habitats are subtropical or tropical moist lowland forests and plantations. It is threatened by habitat loss. Distribution and population The atoll fruit dove is widespread throughout the islands of the Tuamotu Archipelago, French Polynesia. In a 1999 survey it was found to be uncommon on five out of eight islands visited, but others have found it to be abundant on some atolls which have remained free from the ravages of introduced predators. Ecology The atoll fruit dove is the world's only dove in the tropical Pacific that has adapted exclusively to low coral atolls. It lives in forests and abandoned coconut plantations. It mainly feeds on insects and seeds, usually on the ground. This species also eats the leaves of the " tafano" or " kahaia" (''Guettarda speciosa'' ) trees with odorous flowers. Threats ...

Titian Peale
Titian Ramsay Peale (November 17, 1799 – March 13, 1885) was an American artist, naturalist, and explorer from Philadelphia, Pennsylvania. He was a scientific illustrator whose paintings and drawings of wildlife are known for their beauty and accuracy. Peale was a member of several high-profile scientific expeditions. In 1819–20, he and Thomas Say accompanied Stephen Harriman Long on an expedition to the Rocky Mountains. He was also a member of the United States Exploring Expedition (1838–1842). Starting around 1855, Peale became an enthusiastic amateur photographer. Many of his photographs featured buildings and landscapes in and around Washington D.C. He joined a local club with other amateur photographers and participated in field trips, photo exchanges and contests. By the end of the Civil War, his interest in photography waned and he only occasionally took pictures. Biography Family and early life Peale was born on November 17, 1799 in Philosophical Hall, P ...

Coconut
The coconut tree (''Cocos nucifera'') is a member of the palm tree family (biology), family (Arecaceae) and the only living species of the genus ''Cocos''. The term "coconut" (or the archaic "cocoanut") can refer to the whole coconut palm, the seed, or the fruit, which botanically is a drupe, not a Nut (fruit), nut. Originally native to Central Indo-Pacific, they are now ubiquitous in coastal tropical regions and are a cultural icon of the tropics. The coconut tree provides food, fuel, cosmetics, folk medicine and building materials, among many other uses. The inner flesh of the mature seed, as well as the coconut milk extracted from it, forms a regular part of the diets of many people in the tropics and subtropics. Coconuts are distinct from other fruits because their endosperm contains a large quantity of an almost clear liquid, called "coconut water" or "coconut juice". Mature, ripe coconuts can be used as edible seeds, or processed for Coconut oil, oil and Coconut milk, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1848
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 common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have 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 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 fur ...

Endemic Birds Of French Polynesia
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becoming ...

Ptilinopus
The fruit doves, also known as fruit pigeons, are a genus (''Ptilinopus'') of birds in the pigeon and dove family (Columbidae). These colourful, frugivorous doves are found in forests and woodlands in Southeast Asia and Oceania. It is a large genus with over 50 species, some threatened or already extinct. Taxonomy The genus ''Ptilinopus'' was introduced in 1825 by the English naturalist William Swainson with the rose-crowned fruit dove (''Ptilinopus regina'') as the type species. The genus name combines the Ancient Greek words meaning "down feather" with meaning "foot". The many species of this genus can be further grouped by geography and by certain shared characteristics. The fruit doves of the Sunda Islands and northern Australia, such as the pink-headed fruit dove and banded fruit dove, have comparatively longer tails than other species, and are notable for their solid colouration on the head, neck and breast, with a black band across the belly. Another grouping can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deforestation
Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, with half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute. Estimates vary widely as to the extent of deforestation in the tropics. In 2019, nearly a third of the overall tree cover loss, or 3.8 million hectares, occurred within humid tropical primary forests. These are areas of mature rainforest that are especially important for biodiversity and carbon storage. The direct cause of most deforestation is agriculture by far. More than ...

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 ...

Guettarda Speciosa
''Guettarda speciosa'', with common names sea randa, or zebra wood, is a species of shrub in the family Rubiaceae found in coastal habitats in tropical areas around the Pacific Ocean, including the coastline of central and northern Queensland and Northern Territory in Australia, and Pacific Islands, including Micronesia, French Polynesia and Fiji, Malaysia and Indonesia, Maldives and the east coast of Africa. It reaches 6 m in height, has fragrant white flowers, and large green prominently-veined leaves. It grows in sand above the high tide mark. Taxonomy and naming ''Guettarda speciosa'' was originally described by Carl Linnaeus in volume two of his ''Species Plantarum'' in 1753, citing Java as its origin. The genus was named in honour of the 18th century French naturalist Jean-Étienne Guettard, while the specific epithet is derived from the Latin ''speciosus'' 'showy'. It is the type species of the genus. Its closest relatives are all native to the neotropics, yet it has disp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coral Atoll
Corals are colonial marine invertebrates within the subphylum Anthozoa of the phylum Cnidaria. They typically form compact colonies of many identical individual polyps. Coral species include the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton. A coral "group" is a colony of very many genetically identical polyps. Each polyp is a sac-like animal typically only a few millimeters in diameter and a few centimeters in height. A set of tentacles surround a central mouth opening. Each polyp excretes an exoskeleton near the base. Over many generations, the colony thus creates a skeleton characteristic of the species which can measure up to several meters in size. Individual colonies grow by asexual reproduction of polyps. Corals also breed sexually by spawning: polyps of the same species release gametes simultaneously overnight, often around a full moon. Fertilized eggs form planulae, a mobile early form of the coral polyp whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
