Banana
A banana is an elongated, edible fruit – botanically a berry – produced by several kinds of large herbaceous flowering plants in the genus ''Musa''. In some countries, bananas used for cooking may be called "plantains", distinguishing them from dessert bananas. The fruit is variable in size, color, and firmness, but is usually elongated and curved, with soft flesh rich in starch covered with a rind, which may be green, yellow, red, purple, or brown when ripe. The fruits grow upward in clusters near the top of the plant. Almost all modern edible seedless ( parthenocarp) bananas come from two wild species – ''Musa acuminata'' and ''Musa balbisiana''. The scientific names of most cultivated bananas are ''Musa acuminata'', ''Musa balbisiana'', and ''Musa'' × ''paradisiaca'' for the hybrid ''Musa acuminata'' × ''M. balbisiana'', depending on their genomic constitution. The old scientific name for this hybrid, ''Musa sapientum'', is no longer used. ''Musa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1941
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 ...

Aethopyga
''Aethopyga'' is a genus of birds in the sunbird family Nectariniidae. Species in this genus are found in South Asia, Southeast Asia and parts of China. Many species such as the grey-hooded sunbird, Apo sunbird, Apo sunbird, Tboli sunbird, metallic-winged sunbird, handsome sunbird and Lina's sunbird are endemic to the Philippines. Taxonomy The genus ''Aethopyga'' was introduced in 1851 by the German ornithologist Jean Cabanis. The name combines the Ancient Greek ''aithos '' meaning "fire" or "burning heat" with ''pugē'' meaning "rump". The type species was designated as the crimson sunbird by George Robert Gray George Robert Gray FRS (8 July 1808 – 6 May 1872) was an English zoologist and author, and head of the ornithological section of the British Museum, now the Natural History Museum, in London for forty-one years.

Mount Hamiguitan
Mount Hamiguitan is a mountain located in the province of Davao Oriental, Philippines. It has a height of . The mountain and its vicinity has one of the most diverse wildlife populations in the country. Among the wildlife found in the area are Philippine eagles and several species of '' Nepenthes''. Some of the latter, such as the ''Nepenthes peltata'' and ''Nepenthes micramphora'', are endemic to the area. The mountain has a protected forest area of approximately 2,000 hectares. This woodland is noted for its unique pygmy forest of century-old trees in ultramafic soil, with many endangered, endemic and rare species of flora and fauna. The Mount Hamiguitan range, with an area of , was declared a national park and a wildlife sanctuary in 2003. In 2014, the park was inscribed as a UNESCO World Heritage Site, becoming the first in Mindanao and the sixth in the Philippines. Mount Hamiguitan is part of the Eastern Mindanao Biodiversity Corridor. Conservation of the mountain range is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slash-and-burn
Slash-and-burn agriculture is a farming method that involves the cutting and burning of plants in a forest or woodland to create a 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 is burned, resulting in a nutrient-rich layer of ash which makes the 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 practice is known as jhum or jhoom. Slash-and-burn is a type of shif ... [...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. 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 improvements are not able to be depreciated because a useful life cannot be determined. Home building and containment are two of the most common and the oldest types of development. In an urban context, land development furthermore includes: * Road construction ** Access ro ...

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 ...

Near Threatened
A near-threatened species is a species which has been categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature as that may be vulnerable to endangerment in the near future, but it does not currently qualify for the threatened status. The IUCN notes the importance of re-evaluating near-threatened taxon at appropriate intervals. The rationale used for near-threatened taxa usually includes the criteria of vulnerable which are plausible or nearly met, such as reduction in numbers or range. Near-threatened species evaluated from 2001 onwards may also be ones which are dependent on conservation efforts to prevent their becoming threatened, whereas before this conservation-dependent species were given a separate category ("Conservation Dependent"). Additionally, the 402 conservation-dependent taxa may also be considered near-threatened.

Least-concern Species
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...
