Florent Prévost
Florent Prévost (1794 – 1 February 1870) was a French naturalist and illustrator. Prévost was assistant naturalist at the Muséum National d'Histoire Naturelle. He was the author of various zoological works, including ''Les Pigeons par Madame Knip'' (1843) and, with C. L. Lemaire, ''Histoire Naturelle des Oiseaux d'Europe'' (1845). He did illustrative work in books by Coenraad Jacob Temminck (1778–1858), Charles Lucien Bonaparte (1803–1857) and Georges-Louis Leclerc de Buffon (1707–1788). He worked on the birds from the voyage of ''La Venus'' with Marc Athanese Parfait Oeillet Des Murs, and on the birds and mammals brought back from the French expedition to Abyssinia between 1839 and 1843. Prevost's ground sparrow (''Melozone biarcuatum''), Prevost's squirrel (''Callosciurus prevostii''), and Gerard's water snake (''Gerarda prevostiana'') are named after him. Associated writings *''Voyage autour du monde sur la frégate la Vénus pendant les années 1836-1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buru
Buru (formerly spelled Boeroe, Boro, or Bouru) is the third largest island within the Maluku Islands of Indonesia. It lies between the Banda Sea to the south and Seram Sea to the north, west of Ambon and Seram islands. The island belongs to Maluku province and includes the Buru and South Buru regencies. Their administrative centers, Namlea and Namrole, respectively, have ports and are the largest towns of the island, served by Namlea Airport and Namrole Airport. About a third of the population is indigenous, mostly Buru, but also Lisela, Ambelau and Kayeli people. The rest of population are immigrants from Java and nearby Maluku Islands. Religious affiliation is evenly split between Christianity and Sunni Islam, with some remnants of traditional beliefs. While local languages and dialects are spoken within individual communities, the national Indonesian language is used among the communities and by the administration. Most of the island is covered with forests rich in tropic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1843
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. Birds ...

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 John Swainson with the rose-crowned fruit dove (''Ptilinopus regina'') as the type species. The genus name combines the Ancient Greek meaning "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 made of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
African Collared Dove
The African collared dove (''Streptopelia roseogrisea'') is a small dove found in the Sahel, northern parts of the Horn of Africa and southwestern Arabia. Although it lives in arid lands, it is found around water sources. This bird is typically around in length. Its upper body, from shoulders to tail, is a pale grayish brown, though the wing edge has a bluish tinge. Flight feathers are darker, and nearly black. Head, neck and breast are pinkish shading to white on the chin and belly. There is little sexual dimorphism. The African collared dove is the species thought to be the wild ancestor of the domestic Barbary dove, though some suggest the Eurasian collared dove (''Streptopelia decaocto'') may also have been involved. The African collared dove is able to hybridise with the Barbary dove, and it is thought that the increase in the range of colours of Barbary doves available that occurred in the later 20th century was the result of the importation of African collared doves ...

Montane Forest
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subtropical Or Tropical Moist Lowland Forest
Tropical and subtropical moist broadleaf forests (TSMF), also known as tropical moist forest, is a subtropical and tropical forest habitat type defined by the World Wide Fund for Nature. Description TSMF is generally found in large, discontinuous patches centered on the equatorial belt and between the Tropic of Cancer and Tropic of Capricorn, TSMF are characterized by low variability in annual temperature and high levels of rainfall of more than annually. Forest composition is dominated by evergreen and semi-deciduous tree species. These trees number in the thousands and contribute to the highest levels of species diversity in any terrestrial major habitat type. In general, biodiversity is highest in the forest canopy. The canopy can be divided into five layers: overstory canopy with emergent crowns, a medium layer of canopy, lower canopy, shrub level, and finally understory. These forests are home to more species than any other terrestrial ecosystem: Half of the world's sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
