Bokak Atoll
Bokak Atoll ( Marshallese: or , ) or Taongi Atoll is an uninhabited coral atoll in the Ratak Chain of the Marshall Islands, in the North Pacific Ocean. Due to its relative isolation from the main islands in the group, Bokak's flora and fauna has been able to exist in a pristine condition. Geography It is located north of Majuro Atoll, the capital of the Marshall Islands, and northeast of Bikar Atoll, the closest atoll, making it the most northerly and most isolated atoll of the country. Wake Island is north-northwest. The land area is , and the lagoon measures . It consists of 36 islets. The total area is (including reef flat). Physical features The atoll is roughly crescent-shaped, measuring about by , and oriented in a north–south direction. The atoll reef is unbroken except for a wide channel in the west. Ten islets lie on the eastern and southeastern reef. The more important named islets, from north to south, are North Island, Kamwome, Bwdije, Sibylla, Bokak ...

Bunchgrass
Tussock grasses or bunch grasses are a group of grass species in the family Poaceae. They usually grow as singular plants in clumps, tufts, hummocks, or bunches, rather than forming a sod or lawn, in meadows, grasslands, and prairies. As perennial plants, most species live more than one season. Tussock grasses are often found as forage in pastures and ornamental grasses in gardens. Many species have long roots that may reach or more into the soil, which can aid slope stabilization, erosion control, and soil porosity for precipitation absorption. Also, their roots can reach moisture more deeply than other grasses and annual plants during seasonal or climatic droughts. The plants provide habitat and food for insects (including Lepidoptera), birds, small animals and larger herbivores, and support beneficial soil mycorrhiza. The leaves supply material, such as for basket weaving, for indigenous peoples and contemporary artists. Tussock and bunch grasses occur in almost any hab ...

Scaevola Taccada
''Scaevola taccada'', also known as beach cabbage, sea lettuce, or beach naupaka, is a flowering plant in the family Goodeniaceae found in coastal locations in the tropical areas of the Indo-Pacific. It is a common beach shrub throughout the Arabian Sea, the tropical Indian Ocean and the tropical islands of the Pacific Ocean. There has long been confusion over the correct scientific name for this species. It is also known by the synonym ''Scaevola sericea''. Description ''Scaevola taccada'' is a large bush reaching up to about 4 m in height typical of littoral zones where it grows very close to the sea exposed to the salt spray, usually on sandy or pebbly soils. Leaves are slightly succulent, about 20 cm long, closely alternate and crowded at the stem tips. They are glabrous with a fleshy-looking yellowish green color. The fruits and flowers are white. ''Scaevola taccada'' blooms the whole year round and the flowers have a fan-like shape which gives them the name fanf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Understory

English serves as the medium of inter-Commonwealth relations. Many ...), also known as underbrush or undergrowth, includes plant life growing beneath the forest canopy without penetrating it to any great extent, but above the forest floor. Only a small percentage of light penetrates the canopy so understory vegetation is generally shade-tolerant. The understory typically consists of trees stunted through lack of light, other small trees with low light requirements, saplings, shrubs, vines and undergrowth. Small trees such as holly and dogwood are understory specialists. In Temperate broadleaf and mixed forest, temperate deciduous forests, many understory plants start into growth earlier in the year ...

Heliotropium Foertherianum
''Heliotropium arboreum'' is a species of flowering plant in the borage family, Boraginaceae. It is native to tropical Asia including southern China, Madagascar, northern Australia, and most of the atolls and high islands of Micronesia and Polynesia. Common names include velvetleaf soldierbush, tree heliotrope, veloutier, and octopus bush. It is a shrub or small tree typical of littoral zones reaching a height of , with a spread of about . Taxonomy Originally published as ''Tournefortia argentea'', it was transferred to ''Argusia argentea'', and remained under that name until recently. It was subsequently restored to the genus '' Tournefortia'' before being transferred into the genus '' Heliotropium'' under a new name in 2003. Uses Historically in the Maldives the leaves were often used as famine food. Wood The wood of ''H. arboreum'' is commonly used to make handicrafts, tools, and, in Polynesia, frames for swim goggles. Due to its availability, ''H. arboreum'' is used as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coconut
The coconut tree (''Cocos nucifera'') is a member of the palm tree 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. The name comes from the old Portuguese word '' coco'', meaning "head" or "skull", after the three indentations on the coconut shell that resemble facial features. They are 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, form 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 clear liquid, called '' coconut water'' or ''coconut juice''. Mature, ripe co ...

Ghyben-Herzberg Lens
In hydrology, a lens, also called freshwater lens or Ghyben-Herzberg lens, is a convex-shaped layer of fresh groundwater that floats above the denser saltwater and is usually found on small coral or limestone islands and atolls. This aquifer of fresh water is recharged through precipitation that infiltrates the top layer of soil and percolates downward until it reaches the saturated zone. The recharge rate of the lens can be summarized by the following equation: R = p-ET Where R is the recharge rate in meters, p is precipitation (m), and ET is evapotranspiration (m) of water. With higher amounts of recharge, the hydraulic head is increased, and a thick freshwater lens is maintained through the dry season. Lower rates of precipitation or higher rates of interception and evapotranspiration will decrease the hydraulic head, resulting in a thin lens.Bailey, Ryan T., John W. Jenson, and Arne E. Olsen. ''An atoll freshwater lens algebraic model for groundwater management in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arid
A region is arid when it severely lacks available water, to the extent of hindering or preventing the growth and development of plant and animal life. Regions with arid climates tend to lack vegetation and are called xeric or desertic. Most arid climates straddle the Equator; these regions include parts of Africa, Asia, South America, North America, and Australia. Change over time The distribution of aridity at any time is largely the result of the general circulation of the atmosphere. The latter does change significantly over time through climate change. For example, temperature increase by 1.5–2.1 percent across the Nile Basin over the next 30–40 years could change the region from semi-arid to arid, significantly reducing the land usable for agriculture. In addition, changes in land use can increase demands on soil water and thereby increase aridity.

Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
