Pepeopae
Pēpēōpae is a bog on the island of Molokai in Hawaii. Description Pēpēōpae is located near the summit of Kamakou peak in eastern Molokai at an elevation of about at . Poorly draining acidic soil leaches of nutrients, rainfall that exceeds , cooler temperatures and high winds have resulted in a bog where the canopy has been reduced to plants that are only inches above the ground. Typical forest canopy trees such as ''ōhia lehua'' (''Metrosideros polymorpha'') and ''ōlapa'' (''Cheirodendron trigynum'') can be found as groundcover, crawling along the surface. Pēpēōpae bog is home to several endemic and endangered plant and animal species, including the Hawaii bog violet (''Viola maviensis''), ''alani'' (''Melicope'' spp.), sedges, ''lepelepe a moa'' (''Selaginella arbuscula''), among many others. Endemic ''Drosophila'' species, wingless flies, and damselflies can also be found in the bog. The bog is contained within The Nature Conservancy's Kamakou Preserve, and access ...

Molokai
Molokai , or Molokai (), is the fifth most populated of the eight major islands that make up the Hawaiian Islands, Hawaiian Islands archipelago in the middle of the Pacific Ocean. It is 38 by 10 miles (61 by 16 km) at its greatest length and width with a usable land area of , making it the fifth-largest in size of the main Hawaiian Islands and the List of islands of the United States by area, 27th largest island in the United States. It lies southeast of Oahu, Oahu across the wide Hawaiian islands channels, Kaʻiwi Channel and north of Lanai, Lānai, separated from it by the Hawaiian islands channels, Kalohi Channel. The island's agrarian economy has been driven primarily by cattle ranching, pineapple production, sugarcane production and small-scale farming. Tourism comprises a small fraction of the island's economy, and much of the infrastructure related to tourism was closed and barricaded in the early 2000s when the primary landowner, Molokai Ranch, ceased operations due ...

Selaginella
''Selaginella'' is the sole genus of vascular plants in the family Selaginellaceae, the spikemosses or lesser clubmosses. This family is distinguished from Lycopodiaceae (the clubmosses) by having scale-leaves bearing a ligule and by having spores of two types. They are sometimes included in an informal paraphyletic group called the "fern allies". '' S. moellendorffii'' is an important model organism. Its genome has been sequenced by the United States Department of Energy's Joint Genome Institute. The name ''Selaginella'' was erected by Palisot de Beauvois solely for the species ''Selaginella selaginoides'', which turns out (with the closely related ''Selaginella deflexa'') to be a clade that is sister to all other ''Selaginellas'', so any definitive subdivision of the species into separate genera leaves two taxa in ''Selaginella'', with the hundreds of other species in new or resurrected genera. ''Selaginella'' occurs mostly in the tropical regions of the world, with a hand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landforms Of Molokai
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are the fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protected Areas Of Molokai
Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage servin ...

Wetlands Of Hawaii
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils. The primary factor that distinguishes wetlands from terrestrial land forms or Body of water, water bodies is the characteristic vegetation of aquatic plants, adapted to the unique anoxic hydric soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods for assessing wetland functions, wetland ecological health, and general wetland condition have been developed for many regions of the world. These methods have contributed to wetland conservation partly by raising public awareness of the functions some wetlands provide. Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish or saltwater. The main wetland t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawaiian Language
Hawaiian (', ) is a Polynesian language of the Austronesian language family that takes its name from Hawaii, the largest island in the tropical North Pacific archipelago where it developed. Hawaiian, along with English, is an official language of the US state of Hawaii. King Kamehameha III established the first Hawaiian-language constitution in 1839 and 1840. For various reasons, including territorial legislation establishing English as the official language in schools, the number of native speakers of Hawaiian gradually decreased during the period from the 1830s to the 1950s. Hawaiian was essentially displaced by English on six of seven inhabited islands. In 2001, native speakers of Hawaiian amounted to less than 0.1% of the statewide population. Linguists were unsure if Hawaiian and other endangered languages would survive. Nevertheless, from around 1949 to the present day, there has been a gradual increase in attention to and promotion of the language. Public Hawaiian-langua ...

Boardwalk
A boardwalk (alternatively board walk, boarded path, or promenade) is an elevated footpath, walkway, or causeway built with wooden planks that enables pedestrians to cross wet, fragile, or marshy land. They are also in effect a low type of bridge. Such timber trackways have existed since at least Neolithic times. Some wooden boardwalks have had sections replaced by concrete and even "a type of recycled plastic that looks like wood." History An early example is the Sweet Track that Neolithic people built in the Somerset levels, England, around 6000 years ago. This track consisted mainly of planks of oak laid end-to-end, supported by crossed pegs of ash, oak, and lime, driven into the underlying peat. The Wittmoor bog trackway is the name given to each of two prehistoric plank roads, or boardwalks, trackway No. I being discovered in 1898 and trackway No. II in 1904 in the ''Wittmoor'' bog in northern Hamburg, Germany. The trackways date to the 4th and 7th century AD, both linked ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Damselfly
Damselflies are flying insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies, which constitute the other odonatan suborder, Anisoptera, but are smaller and have slimmer bodies. Most species fold the wings along the body when at rest, unlike dragonflies which hold the wings flat and away from the body. An ancient group, damselflies have existed since at least the Lower Permian, and are found on every continent except Antarctica. All damselflies are predatory insects; both nymphs and adults actively hunt and eat other insects. The nymphs are aquatic, with different species living in a variety of freshwater habitats including acidic bogs, ponds, lakes and rivers. The nymphs moult repeatedly, at the last moult climbing out of the water to undergo metamorphosis. The skin splits down the back, they emerge and inflate their wings and abdomen to gain their adult form. Their presence on a body of water indicates that it is relatively unpolluted, but the ...

Drosophila
''Drosophila'' () is a genus of flies, belonging to the family Drosophilidae, whose members are often called "small fruit flies" or (less frequently) pomace flies, vinegar flies, or wine flies, a reference to the characteristic of many species to linger around overripe or rotting fruit. They should not be confused with the Tephritidae, a related family, which are also called fruit flies (sometimes referred to as "true fruit flies"); tephritids feed primarily on unripe or ripe fruit, with many species being regarded as destructive agricultural pests, especially the Mediterranean fruit fly. One species of ''Drosophila'' in particular, ''D. melanogaster'', has been heavily used in research in genetics and is a common model organism in developmental biology. The terms "fruit fly" and "''Drosophila''" are often used synonymously with ''D. melanogaster'' in modern biological literature. The entire genus, however, contains more than 1,500 species and is very diverse in appearance, be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melicope
''Melicope'' is a genus of about 240 species of shrubs and trees in the family Rutaceae, occurring from the Hawaiian Islands across the Pacific Ocean to tropical Asia, Australia and New Zealand. Plants in the genus ''Melicope'' have simple or trifoliate leaves arranged in opposite pairs, flowers arranged in panicles, with four sepals, four petals and four or eight stamens and fruit composed of up to four follicles. Description Plants in the genus ''Melicope'' have simple or trifoliate leaves arranged in opposite pairs, or sometimes whorled. The flowers are arranged in panicles and are bisexual or sometimes with functionally male- or female-only flowers. The flowers have four sepals, four petals and four or eight stamens. There are four, sometimes five, carpels fused at the base with fused styles, the stigma similar to the tip of the style. The fruit is composed of up to four follicles fused at the base, each with one or two seeds. Taxonomy The genus ''Melicope'' was first ...
