Crotalaria Avonensis
''Crotalaria avonensis'' is a rare species of flowering plant in the legume family known by the common names Avon Park rattlebox, Avon Park harebells, and Avon Park rabbit-bells. It is endemic to Central Florida in the United States, where it is known from only three sites. Many individuals exist on land that is unprotected and they are threatened with destruction. The plant is a federally listed endangered species. This is a perennial herb with one to three hairy stems growing from a taproot. Most of the stem is located underground, with up to 10 centimeters growing above the surface. The stems are lined with fleshy oval leaves which are coated in white or yellowish hairs. The inflorescence is a raceme of yellow pealike flowers around a centimeter long. The fruit is an inflated legume pod in shades of dark red or brown which can be up to 2.5 centimeters in length and contains 18 seeds. After the plant flowers in spring it becomes dormant for the rest of the year. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Orange (fruit)
An orange is a fruit of various citrus species in the family Rutaceae (see list of plants known as orange); it primarily refers to ''Citrus'' × ''sinensis'', which is also called sweet orange, to distinguish it from the related ''Citrus × aurantium'', referred to as bitter orange. The sweet orange reproduces asexually (apomixis through nucellar embryony); varieties of sweet orange arise through mutations. The orange is a hybrid between pomelo (''Citrus maxima'') and mandarin (''Citrus reticulata''). The chloroplast genome, and therefore the maternal line, is that of pomelo. The sweet orange has had its full genome sequenced. The orange originated in a region encompassing Southern China, Northeast India, and Myanmar, and the earliest mention of the sweet orange was in Chinese literature in 314 BC. , orange trees were found to be the most cultivated fruit tree in the world. Orange trees are widely grown in tropical and subtropical climates for their sweet fruit. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fecundity
Fecundity is defined in two ways; in human demography, it is the potential for reproduction of a recorded population as opposed to a sole organism, while in population biology, it is considered similar to fertility, the natural capability to produce offspring, measured by the number of gametes (eggs), seed set, or asexual propagules. Superfecundity refers to an organism's ability to store another organism's sperm (after copulation) and fertilize its own eggs from that store after a period of time, essentially making it appear as though fertilization occurred without sperm (i.e. parthenogenesis). Human demography Human demography considers only human fecundity, at its culturally differing rates, while population biology studies all organisms. The term ''fecundity'' in population biology is often used to describe the rate of offspring production after one time step (often annual). In this sense, fecundity may include both birth rates and survival of young to that time step. W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological Life Cycle
In biology, a biological life cycle (or just life cycle or lifecycle when the biological context is clear) is a series of changes in form that an organism undergoes, returning to the starting state. "The concept is closely related to those of the life history, development and ontogeny, but differs from them in stressing renewal." Transitions of form may involve growth, asexual reproduction, or sexual reproduction. In some organisms, different "generations" of the species succeed each other during the life cycle. For plants and many algae, there are two multicellular stages, and the life cycle is referred to as alternation of generations. The term life history is often used, particularly for organisms such as the red algae which have three multicellular stages (or more), rather than two.Dixon, P.S. 1973. ''Biology of the Rhodophyta.'' Oliver & Boyd. Life cycles that include sexual reproduction involve alternating haploid (''n'') and diploid (2''n'') stages, i.e., a change of ...

Cladonia Perforata
''Cladonia perforata'' is a rare species of lichen known as Florida perforate cladonia and Florida perforate reindeer lichen. It is endemic to the state of Florida in the United States, where it is known from 16 populations in four widely separated areas of the state.USFWS''Cladonia perforata'' Five-year Review.2007. It is native to a very specific type of Florida scrub habitat which is increasingly rare and patchy due to habitat destruction, degradation, and fragmentation. In 1993 this was the first species of lichen to be federally listed as an endangered species of the United States.Teague, D. and D. RipleyA tale of two species.''Endangered Species Bulletin''.

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, defacement directed towards any property without permission of the owner. The term finds its roots in an Age of Enlightenment, 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 (455), sack of Rome under King Genseric in 455. During the Age of Enlightenment, 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 ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digitaria Eriantha
''Digitaria eriantha'', commonly known as digitgrass or Pangola-grass, is a grass grown in tropical and subtropical climates. It grows relatively well in various soils, but grows especially well in moist soils. It is tolerant to droughts, water lodging, suppresses weeds and grows relatively quickly after grazing. This grass demonstrates great potential for farmers in Africa in subtropical and tropical climates, mostly for livestock feed. Description ''Digitaria eriantha'' is a monocot and in the family of Poaceae. "It is perennial, sometimes stoloniferous or tufted". This grass grows a dense tussock with extended stolons, which are covered with hairs or without hairs. Each grass, erect or ascending, reaches between 35 and 180 cm tall. The lowest basal leaf sheaths are densely hairy, or very rarely smooth. The leaf blades are typically 5–60 cm long, 2–14 mm wide and may be either hairy or smooth. Each inflorescence typically has six or seven spicate branches, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imperata Cylindrica
''Imperata cylindrica'' (commonly known as cogongrass or kunai grass ) is a species of perennial rhizomatous grass native to tropical and subtropical Asia, Micronesia, Melanesia, Australia, Africa, and southern Europe. It has also been introduced to Latin America, the Caribbean, and the southeastern United States. It is a highly flammable pyrophyte, and can spread rapidly by colonizing disturbed areas and encouraging more frequent wildfires. Common names The species is most commonly known in English as "cogongrass", from Spanish ''cogón'', from the Tagalog and Visayan ''kugon''. Other common names in English include ''kunai grass'', ''blady grass'', ''satintail'', ''spear grass'', ''sword grass'', ''thatch grass'', ''alang-alang'', ''lalang grass'', ''cotton wool grass'', and ''kura-kura'' , among other names. Description It grows from 0.6 to 3 m (2 to 10 feet) tall. The leaves are about 2 cm wide near the base of the plant and narrow to a sharp point at th ...

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] |
Road
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheel ...
