Slaty-backed Jungle Flycatcher
The slaty-backed jungle flycatcher (''Vauriella goodfellowi''), also known as the Goodfellow's jungle flycatcher or the Mindanao jungle flycatcher is a species of bird in the Old World flycatcher family Muscicapidae. It is endemic to the Philippines found only on the island of Mindanao. The specific epithet honours the British zoological collector Walter Goodfellow. Its natural habitat is tropical moist montane forests. It is threatened by habitat loss Description and taxonomy EBird describes the bird as "A medium-sized bird of mossy montane forest understory on Mindanao. Large for a flycatcher. Dark brown above, with pale gray-brown chest and sides and a white throat and belly. Note the white spectacles and forehead with a thin black eye-ring and black line connecting the eye and bill. Somewhat similar to Chestnut-tailed Flycatcher, but found at higher elevations and has obvious black-and-white lines in front of the eye. Voice includes high-pitched metallic whistles and a sha ...

Eyebrowed Jungle Flycatcher
The eyebrowed jungle flycatcher (''Vauriella gularis'') is a species of bird in the Old World flycatcher family Muscicapidae. It is endemic to the island of Borneo (elevated areas, including the Meratus Mountains). The natural habitat of the eyebrowed jungle flycatcher is subtropical or tropical moist montane forests. It builds an open, mossy cup nest, generally in epiphytes or spiny palms. This species was previously placed in the genus ''Rhinomyias'' but was moved to ''Vauriella'' when a molecular phylogenetic study published in 2010 found that ''Rhinomyias'' was polyphyletic A polyphyletic group is an assemblage that includes organisms with mixed evolutionary origin but does not include their most recent common ancestor. The term is often applied to groups that share similar features known as Homoplasy, homoplasies ....

Birds Described In 1905
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 furth ...

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups w ...

Kitanglad Mountain Range
The Kitanglad Mountain Range dominates the northern central portion of the province of Bukidnon, Philippines. It occupies portions of eight of the municipalities and cities in the province such as Talakag, Baungon, Libona, Manolo Fortich, Impasugong, Lantapan and Malaybalay. The range is one of the few remaining rainforests in the Philippines, hosting one of the most important diverse species of rare and endemic wildlife such as the Philippine eagle. Five of its peaks have very high elevations: Mount Dulang-dulang, the highest at ; Mount Kitanglad at 2,899 meters; Mount Maagnaw at 2,742 meters; Mount Lumuluyaw at 2,612 meters; and Mount Tuminungan at 2,400 meters. The name ''"kitanglad"'' was derived from a legend that there was once a great flood that submerged the native lands of Bukidnon and only the tip of the mountain, the size of a ''"tanglad"'' (lemon grass), remained visible (''"kita"'' in Cebuano).

Mount Apo
Mount Apo is the highest mountain peak in the Philippines, with an elevation of above sea level. A large solfataric, dormant stratovolcano, it is part of the Apo-Talomo Mountain Range of Mindanao island. Apo is situated on the tripartite border of Davao City, Davao del Sur, and Cotabato; its peak is visible from Davao City to the northeast, Digos to the southeast, and Bansalan to the west. Apo is a protected area and is the centerpiece of Mount Apo Natural Park. Geology Mount Apo is a flat-topped, (above sea level) high stratovolcano with three peaks. It is the highest peak of the Philippines. The southwest peak has the highest elevation and is topped by a wide crater that contains a small lake. The volcanic history of Mount Apo is poorly known but eruptions have produced andesitic-to- dacitic lava. A line of solfataras extend from the southeast flank at an elevation of to the summit. Mount Apo is not known to have had historical eruptions, and was incorrectly attr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slash-and-burn
Slash-and-burn agriculture is a form of shifting cultivation that involves the cutting and burning of plants in a forest or woodland to create a Field (agriculture), field called a swidden. The method begins by cutting down the trees and woody plants in an area. The downed vegetation, or "slash", is then left to dry, usually right before the rainiest part of the year. Then, the Biomass (ecology), biomass is burned, resulting in a nutrient-rich layer of ash which makes the Soil fertility, soil fertile, as well as temporarily eliminating weed and pest species. After about three to five years, the plot's productivity decreases due to depletion of nutrients along with weed and pest invasion, causing the farmers to abandon the field and move to a new area. The time it takes for a swidden to recover depends on the location and can be as little as five years to more than twenty years, after which the plot can be slashed and burned again, repeating the cycle. In Bangladesh and India, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Land Conversion
Land development is the alteration of landscape in any number of ways, such as: * Changing landforms from a natural or semi-natural state for a purpose such as agriculture or housing * Subdividing real estate into lots, typically for the purpose of building homes * Real estate development or changing its purpose, for example by converting an unused factory complex into a condominium History Land development has a history dating to Neolithic times around 8,000 BC. From the dawn of civilization, the process of land development has elaborated the progress of improvements on a piece of land based on codes and regulations, particularly housing complexes. Economic aspects In an economic context, land development is also sometimes advertised as land improvement or land amelioration. It refers to investment making land more usable by humans. For accounting purposes, it refers to any variety of projects that increase the value of the process. Most are depreciable, but some land improv ...

Near Threatened
A near-threatened species is a species which has been Conservation status, categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature (IUCN) as that may be vulnerable to Endangered species, endangerment in the near future, but it does not currently qualify for the threatened status. The IUCN notes the importance of reevaluating near-threatened taxon, taxa at appropriate intervals. The rationale used for near-threatened taxa usually includes the criteria of Vulnerable species, vulnerable which are plausible or nearly met, such as reduction in numbers or range. Those designated since 2001 that depend on conservation efforts to not become threatened are no longer separately considered conservation-dependent species. IUCN Categories and Criteria version 2.3 Before 2001, the IUCN used the version 2.3 Categories and Criteria to assign conservation status, which included a separate category for conservation-dependent species ("Conservation Dependen ...

Rhinomyias Goodfellowi Goodchild (cropped)
''Cyornis'' is a genus of birds in the Old World flycatcher family Muscicapidae most of which are native to Southeast Asia. Taxonomy The genus ''Cyornis'' was introduced by the English zoologist Edward Blyth in 1843. He listed three species in the genus but did not specify which he considered to be the type species. The type was subsequently designated by George Robert Gray, George Gray in 1855 as ''Phoenicura rubeculoides'' Nicholas Aylward Vigors, Vigors, 1831, the blue-throated blue flycatcher. The genus name combines the Ancient Greek ''kuanos'' meaning "dark-blue" with ''ornis'' meaning "bird". Species The genus contains the following 32 species: Seven of the above species, all with "jungle flycatcher" in their English names, were previously placed in the genus ''Rhinomyias'' but were moved to ''Cyornis'' based on the results of a 2010 molecular phylogenetic study. There are also "jungle flycatchers" in the genus ''Vauriella''. References Further reading * Del Hoy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyphyletic
A polyphyletic group is an assemblage that includes organisms with mixed evolutionary origin but does not include their most recent common ancestor. The term is often applied to groups that share similar features known as Homoplasy, homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. [Source for pronunciation.] It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthesis, C4 photosynthetic plants, and Xenarthra#Evolutionary relationships, edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major re ...
