Canebrake
A canebrake or canebreak is a thicket of any of a variety of ''Arundinaria'' grasses: '' A. gigantea'', '' A. tecta'' and '' A. appalachiana''. As a bamboo, these giant grasses grow in thickets up to 24 ft tall. ''A. gigantea'' is generally found in stream valleys and ravines throughout the southeastern United States. ''A. tecta'' is a smaller stature species found on the Atlantic and Gulf Coastal Plains. Finally, ''A. appalachiana'' is found in more upland areas at the southern end of the Appalachian mountains. Cane does not do well on sites that meet wetland classification; instead canebrakes are characteristic of moist lowland, floodplain areas that are not as saturated as true wetlands. Canebrakes were formerly widespread in the Southern United States, potentially covering 10 million acres, but have been widely replaced by agriculture. This destruction has impacted a number of species. The survival of the Florida panther (''Puma concolor'' subsp. ''coryi'') has been chal ...

Arundinaria Gigantea
''Arundinaria gigantea'' is a species of bamboo known as giant cane (not to be confused with ''Arundo donax''), river cane, and giant river cane. It is endemic to the south-central and southeastern United States as far west as Oklahoma and Texas and as far north as New York. Giant river cane was economically and culturally important to indigenous people, with uses including as a vegetable and materials for construction and craft production. Arundinaria gigantea and other species of ''Arundinaria'' once grew in large colonies called canebrakes covering thousands of acres in the southeastern United States, but today these canebrakes are considered endangered ecosystems. Description This bamboo, which is a species of cane, is a perennial grass with a rounded, hollow stem which can exceed in diameter and grow to a height of . It grows from a large network of thick rhizomes. The lance-shaped leaves are up to long and wide. The inflorescence is a raceme or panicle of spikelets measur ...

Dionaea Muscipula
The Venus flytrap (''Dionaea muscipula'') is a carnivorous plant native to subtropical wetlands on the East Coast of the United States in North Carolina and South Carolina. It catches its prey—chiefly insects and arachnids—with a trapping structure formed by the terminal portion of each of the plant's leaves, which is triggered by tiny hairs (called "trigger hairs" or "sensitive hairs") on their inner surfaces. When an insect or spider crawling along the leaves contacts a hair, the trap prepares to close, snapping shut only if another contact occurs within approximately twenty seconds of the first strike. Triggers may occur with a tenth of a second of contact. The requirement of redundant triggering in this mechanism serves as a safeguard against wasting energy by trapping objects with no nutritional value, and the plant will only begin digestion after five more stimuli to ensure it has caught a live bug worthy of consumption. ''Dionaea'' is a monotypic genus closely relat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Riparian Zone
A riparian zone or riparian area is the interface between land and a river or stream. Riparian is also the proper nomenclature for one of the terrestrial biomes of the Earth. Plant habitats and communities along the river margins and banks are called riparian vegetation, characterized by hydrophilic plants. Riparian zones are important in ecology, environmental resource management, and civil engineering because of their role in soil conservation, their habitat biodiversity, and the influence they have on fauna and aquatic ecosystems, including grasslands, woodlands, wetlands, or even non-vegetative areas. In some regions, the terms riparian woodland, riparian forest, riparian buffer zone, riparian corridor, and riparian strip are used to characterize a riparian zone. The word ''riparian'' is derived from Latin '' ripa'', meaning " river bank". Characteristics Riparian zones may be natural or engineered for soil stabilization or restoration. These zones are important na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arundinaria
''Arundinaria'' is a genus of bamboo in the grass family the members of which are referred to generally as cane. ''Arundinaria'' is the only bamboo native to south and southeastern North America, with a native range from Maryland south to Florida and west to the southern Ohio Valley and Texas. Within this region they are found from the Coastal Plain to medium elevations in the Appalachian Mountains. Arundinaria species have running rhizomes and have slender, woody culms that reach heights from . ''Arundinaria'' produce seeds only rarely and usually reproduce vegetatively, forming large clonal genets. When seed production does occur, the colony usually dies afterwards, possibly because the dense thickets of a mature canebrake would otherwise prevent seedling establishment. Only two flowering events are known for A. appalachiana. Among the distinctive features of the canes is a fan-like cluster of leaves at the top of new stems called a topknot, so-called because of its resembla ...

Arundinaria Appalachiana
''Arundinaria appalachiana'', commonly known as hill cane, is a woody bamboo native to the Appalachian Mountains in the southeastern United States. The plant was elevated to the species level in 2006 based on new morphological and genetic information and was previously treated as a variety of ''Arundinaria tecta''. As a relatively small member of its genus, it usually only attains heights of 0.5 to 1.0 metre with an either dense or diffuse habit. It is one of only three temperate species of bamboo native to North America. Hill cane is common on dry to mesic sites on upland slopes, bluffs and ridges in oak-hickory forests, which distinguishes it from other species in the genus: ''Arundinaria gigantea'' typically appears along perennial streams, while ''Arundinaria tecta'' is found in swamps and other very wet areas. Taxonomy There has long been question to the taxonomic status of the eastern North American bamboos. Two species were originally described by Thomas Walter in 1788, n ...

Bamboo
Bamboos are a diverse group of evergreen perennial flowering plants making up the subfamily Bambusoideae of the grass family Poaceae. Giant bamboos are the largest members of the grass family. The origin of the word "bamboo" is uncertain, but it probably comes from the Dutch or Portuguese language, which originally borrowed it from Malay or Kannada. In bamboo, as in other grasses, the internodal regions of the stem are usually hollow and the vascular bundles in the cross-section are scattered throughout the stem instead of in a cylindrical arrangement. The dicotyledonous woody xylem is also absent. The absence of secondary growth wood causes the stems of monocots, including the palms and large bamboos, to be columnar rather than tapering. Bamboos include some of the fastest-growing plants in the world, due to a unique rhizome-dependent system. Certain species of bamboo can grow within a 24-hour period, at a rate of almost an hour (equivalent to 1 mm every 90 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bachman's Warbler
Bachman's warbler (''Vermivora bachmanii'') is a likely extinct passerine migratory bird. This warbler was a migrant, breeding in swampy blackberry and cane thickets of the Southeastern and Midwestern United States and wintering in Cuba. There are some reports of the bird from the twenty-first century, but none are widely accepted. Some authorities accept a sighting in Louisiana, in August 1988 as confirmed, but the last uncontroversial sightings date to the 1960s. Taxonomy This bird was first recorded in 1832 by the Reverend John Bachman, who found the species near Charleston, South Carolina, and presented study skins and descriptions to his friend and collaborator, John James Audubon. Audubon never saw the bird alive but named it in honor of Bachman in 1833. The blue-winged and rapidly declining golden-winged warblers, also members of the genus '' Vermivora'', are thought to be this warbler's closest relatives. There are no known subspecies.

Sarracenia Alabamensis
''Sarracenia alabamensis'', also known as the cane-brake pitcher plant, is a carnivorous plant in the genus ''Sarracenia''. Like all the ''Sarracenia'', it is native to the New World. ''S. alabamensis'' subsp. ''alabamensis'' is found only in central Alabama, while subsp. ''wherryi'' is found in southwestern Alabama, eastern Mississippi and Florida. It is sometimes treated as two subspecies of '' S. rubra''.Rice, B.A. (2006)The Carnivorous Plant FAQ: ''Sarracenia alabamensis'' Accessed 6 May 2009. Morphology and carnivory Like other members of the genus ''Sarracenia'', ''S. alabamensis'' traps insects using a rolled leaf, which in this species is finely pubescent and between 20 cm and 65 cm tall. It also forms large clumps within a few years. The uppermost part of the leaf is flared into a lid (the operculum), which prevents excess rain from entering the pitcher and diluting the digestive secretions within. The upper regions of the pitcher are covered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eupatorium Resinosum
''Eupatorium resinosum'', the pine barren thoroughwort, is a rare North American plant species in the family Asteraceae. ''Eupatorium resinosum'' is native to the eastern coastal states of the United States, though with a discontinuous distribution. Some populations grow in the Carolinas, others in New Jersey. It formerly grew in New York and Delaware, but is now apparently extirpated there. There are no reports of the species in Maryland or Virginia in between. ''Eupatorium resinosum'' has stems up to 100 cm (40 inches) tall and produce short rhizomes. The inflorescences are composed of a large number of tiny white flower heads with 7-11 disc florets but no ray florets. This species typically grows in moist areas, areas with acidic soils, and pine barrens. It is pollinated by insects and is self-incompatible. It is rare, with only dozens of populations known, and has been extirpated from several states due to habitat destruction Habitat destruction (also termed hab ...

Colony (biology)
In biology, a colony is composed of two or more conspecific individuals living in close association with, or connected to, one another. This association is usually for mutual benefit such as stronger defense or the ability to attack bigger prey. Colonies can form in various shapes and ways depending on the organism involved. For instance, the bacterial colony is a cluster of identical cells (clones). These colonies often form and grow on the surface of (or within) a solid medium, usually derived from a single parent cell. Colonies, in the context of development, may be composed of two or more unitary (or solitary) organisms or be modular organisms. Unitary organisms have determinate development (set life stages) from zygote to adult form and individuals or groups of individuals (colonies) are visually distinct. Modular organisms have indeterminate growth forms (life stages not set) through repeated iteration of genetically identical modules (or individuals), and it can be diffi ...
