Campanula Robinsiae
''Campanula robinsiae'' is a rare species of flowering plant in the bellflower family known by the common names Brooksville bellflower, Robins' bellflower, and Chinsegut bellflower. It is endemic to Florida, where it is known from four or five occurrences in Hernando and Hillsborough Counties.USFWSBrooksville Bellflower: Five-year Review.May 10, 2010. Its population has fluctuated throughout the years; at one point in the early 1980s it was feared extinct.Clear, MA rare flower makes botanists think again.''St. Petersburg Times'' September 24, 2007. Today there are two populations in Hernando County and probably three in Hillsborough River State Park. At the time the plant was listed as an endangered species of the United States in 1989, it was known from three small populations on wet prairies that were threatened by changes in the local hydrology and by pollution.USFWSEndangered status for four Florida plants.''Federal Register'' July 27, 1989.

Campanulaceae
The family Campanulaceae (also bellflower family), of the order Asterales, contains nearly 2400 species in 84 genera of herbaceous plants, shrubs, and rarely small trees, often with milky sap. Among them are several familiar garden plants belonging to the genera ''Campanula'' (bellflower), '' Lobelia'', and ''Platycodon'' (balloonflower). '' Campanula rapunculus'' (rampion or r. bellflower) and ''Codonopsis lanceolata'' are eaten as vegetables. '' Lobelia inflata'' (indian tobacco), '' L. siphilitica'' and '' L. tupa'' (devil's tobacco) and others have been used as medicinal plants. '' Campanula rapunculoides'' (creeping bellflower) may be a troublesome weed, particularly in gardens, while '' Legousia'' spp. may occur in arable fields. Most current classifications include the segregate family Lobeliaceae in Campanulaceae as subfamily Lobelioideae. A third subfamily, Cyphioideae, includes the genus '' Cyphia'', and sometimes also the genera '' Cyphocarpus'', '' Nemacladus'', '' ...

Grazing
In agriculture, grazing is a method of animal husbandry whereby domestic livestock are allowed outdoors to roam around and consume wild vegetations in order to convert the otherwise indigestible (by human gut) cellulose within grass and other forages into meat, milk, wool and other animal products, often on land unsuitable for arable farming. Farmers may employ many different strategies of grazing for optimum production: grazing may be continuous, seasonal, or rotational within a grazing period. Longer rotations are found in ley farming, alternating arable and fodder crops; in rest rotation, deferred rotation, and mob grazing, giving grasses a longer time to recover or leaving land fallow. Patch-burn sets up a rotation of fresh grass after burning with two years of rest. Conservation grazing proposes to use grazing animals to improve the biodiversity of a site, but studies show that the greatest benefit to biodiversity comes from removing grazing animals from the landscape. ...

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 neop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface Runoff
Surface runoff (also known as overland flow) is the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is saturated by water to its full capacity, and the rain arrives more quickly than the soil can absorb it. Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or man-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. Runoff that occurs on the ground surface before reaching a channel can be a nonpoint source of pollution, as it can carry man-made contaminants or natural forms of pollution (such as rotting leaves). Man-made contaminants in run ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drought
A drought is defined as drier than normal conditions.Douville, H., K. Raghavan, J. Renwick, R.P. Allan, P.A. Arias, M. Barlow, R. Cerezo-Mota, A. Cherchi, T.Y. Gan, J. Gergis, D. Jiang, A. Khan, W.

House
A house is a single-unit residential building. It may range in complexity from a rudimentary hut to a complex structure of wood, masonry, concrete or other material, outfitted with plumbing, electrical, and heating, ventilation, and air conditioning systems.Schoenauer, Norbert (2000). ''6,000 Years of Housing'' (rev. ed.) (New York: W.W. Norton & Company). Houses use a range of different roofing systems to keep precipitation such as rain from getting into the dwelling space. Houses may have doors or locks to secure the dwelling space and protect its inhabitants and contents from burglars or other trespassers. Most conventional modern houses in Western cultures will contain one or more bedrooms and bathrooms, a kitchen or cooking area, and a living room. A house may have a separate dining room, or the eating area may be integrated into another room. Some large houses in North America have a recreation room. In traditional agriculture-oriented societies, domestic animals such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered Species Act
The Endangered Species Act of 1973 (ESA or "The Act"; 16 U.S.C. § 1531 et seq.) is the primary law in the United States for protecting imperiled species. Designed to protect critically imperiled species from extinction as a "consequence of economic growth and development untempered by adequate concern and conservation", the ESA was signed into law by President Richard Nixon on December 28, 1973. The Supreme Court of the United States described it as "the most comprehensive legislation for the preservation of endangered species enacted by any nation"."Tennessee Valley Authority v. Hill" 437 U.S. 153 (1978) Retrieved 24 November 2015. The purposes of the ESA are two-fold: to prevent extinction and to recover species to the point where the law's protections are not needed. It therefor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hardwood Forest
Temperate broadleaf and mixed forest is a temperate climate terrestrial habitat type defined by the World Wide Fund for Nature, with broadleaf tree ecoregions, and with conifer and broadleaf tree mixed coniferous forest ecoregions. These forests are richest and most distinctive in central China and eastern North America, with some other globally distinctive ecoregions in the Caucasus, the Himalayas, Southern Europe, Australasia, Southwestern South America and the Russian Far East. Ecology The typical structure of these forests includes four layers. * The uppermost layer is the canopy composed of tall mature trees ranging from high. Below the canopy is the three-layered, shade-tolerant understory that is roughly shorter than the canopy. * The top layer of the understory is the sub-canopy composed of smaller mature trees, saplings, and suppressed juvenile canopy layer trees awaiting an opening in the canopy. * Below the sub-canopy is the shrub layer, composed of low gro ...

Seep (hydrology)
A seep or flush is a moist or wet place where water, usually groundwater, reaches the earth's surface from an underground aquifer. Description Seeps are usually not of sufficient volume to be flowing beyond their immediate above-ground location. They are part of the limnology-geomorphology system. Like a higher volume spring, the water is only from underground sources. Seeps mostly occur in lower elevation areas because water runs downhill, but can happen higher up if the groundwater present is abundant enough. Along with natural seeps, man made seeps can occur by digging anywhere where there is wet ground. This method can be useful for survival purposes and helps the local wildlife by adding another water source to the area. Seeps often form a puddle, and are important for small wildlife, bird, and butterfly habitat and moisture needs. When they support mud-puddling many butterfly (''Lepidoptera'') species can obtain nutrients such as salts and amino acids, including some types ...

Pond
A pond is an area filled with water, either natural or artificial, that is smaller than a lake. Defining them to be less than in area, less than deep, and with less than 30% emergent vegetation helps in distinguishing their ecology from that of lakes and wetlands.Clegg, J. (1986). Observer's Book of Pond Life. Frederick Warne, London Ponds can be created by a wide variety of natural processes (e.g. on floodplains as cutoff river channels, by glacial processes, by peatland formation, in coastal dune systems, by beavers), or they can simply be isolated depressions (such as a kettle hole, vernal pool, prairie pothole, or simply natural undulations in undrained land) filled by runoff, groundwater, or precipitation, or all three of these. They can be further divided into four zones: vegetation zone, open water, bottom mud and surface film. The size and depth of ponds often varies greatly with the time of year; many ponds are produced by spring flooding from rivers. Ponds may b ...

Paederia Foetida
''Paederia foetida'' is a species of plant, with common names that are variations of skunkvine, stinkvine, or Chinese fever vine. It is native to temperate, and tropical Asia; and has become naturalized in the Mascarenes, Melanesia, Polynesia, and the Hawaiian Islands, also found in North America by recent studies. ''Paederia foetida'' is known for the strong, sulphurous odour exuded when its leaves or stems are crushed or bruised. This is because the oil responsible for the smell, and found primarily within the leaves, contains sulphur compounds, including largely dimethyl disulphide. Distribution ''P. foetida'' is native to Bangladesh and southern Bhutan; Cambodia; Taiwan and China (in Hong Kong and Macau, and the provinces of Anhui, Fujian, Gansu, Guangdong, Guangxi, Hainan, Henan, Hubei, Hunan, Jiangsu, Jiangxi, Shaanxi, Shandong, Shanxi, Sichuan, Xizang, Yunnan, Zhejiang); India (in Andhra Pradesh, Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Od ...

Vandalism
Vandalism is the action involving deliberate destruction of or damage to public or private property. The term includes property damage, such as graffiti and defacement directed towards any property without permission of the owner. The term finds its roots in an Enlightenment view that the Germanic Vandals were a uniquely destructive people. Etymology The Vandals, an ancient Germanic people, are associated with senseless destruction as a result of their sack of Rome under King Genseric in 455. During the Enlightenment, Rome was idealized, while the Goths and Vandals were blamed for its destruction. The Vandals may not have been any more destructive than other invaders of ancient times, but they did inspire English poet John Dryden to write, ''Till Goths, and Vandals, a rude Northern race, Did all the matchless Monuments deface'' (1694). However, the Vandals did intentionally damage statues, which may be why their name is associated with the vandalism of art. The ter ...
