Species Last Updated on 2014-09-15 11:53:19 A species is a group of organisms capable of interbreeding and producing fertile offspring of both genders, and separated from other such groups with which interbreeding does not characteristically occur: however, for asexual organisms, a distinct species may be considered a collection of organisms which have very similar DNA or physical characteristics. Certain species are further subdivided into subspecies. The early Greeks and Romans had a well established set of taxonomic names for species of animals and plants, based upon the macroscopically observable characteristics of organisms, with Aristotle being the chief architect of this codification; even earlier, the Egyptians and Cretans developed basic symbols and names for species important in farming and culture. It was not until the year 1686 when English naturalist John Ray introduced the concept that species were... More »
Amphibian Last Updated on 2014-09-09 10:57:59 The term amphibian comes from the Greek amphibios meaning "both lives". This is an apt description because most adult amphibians are better adapted to life on land than in water, while their larval phases are entirely aquatic. For much of their lives, which may last a couple of months or several years depending on the species, larval amphibians bear little resemblance to their adult forms. Then something miraculous happens. In a matter of weeks or even days, the once fish-like larvae metamorphose into terrestrial, air-breathing quadrupeds! There are three extant orders in the Class Amphibia: Anura (frogs and toads), Caudata (salamanders), and Apoda (caecilians). The order Anura has the most extant species, with 4000 members worldwide. Of Caudata, 390 salamander species exist worldwide. The third amphibian group, the caecilians, is smaller still with a total of only 162... More »
Angiosperm Last Updated on 2014-09-09 10:39:17 The Angiosperms, or flowering plants, described taxonomically as the division Magnoliophyta, are the largest grouping within the plant kingdom (Kingdom ''Plantae'' or "Viridiplantae") in terms of the numbers of described species.  Approximately 260,000 species of flowering plant have been named so far -- constituting nearly 90% of all known species of plants. Even so, taxonomists describe many new species annually, and estimates of total angiosperm diversity reach as high as 400,000 species.  There are about 450 families of flowering plants, and they display extremely diverse life-histories and ecological adaptations.  In addition to dominating plant biodiversity, angiosperms are the dominant photosynthesis/photosynthetic organisms (primary producers) in most terrestrial ecosystems (an important exception to this rule are the boreal forests,...

Plant Last Updated on 2014-09-08 22:26:25 A plant is any one of the vast number of organisms within the biological kingdom Plantae; in general, these species are considered of limited motility and generally manufacture their own food. They include a host of familiar organisms including trees, forbs, shrubs, grasses, vines, ferns, and mosses. Conventionally the term plant implies a taxon with characteristics of multicellularity, cell structure with walls containing cellulose, and organisms capable of photosynthesis. Modern classification schemes are driven by somewhat rigid categorizations inherent in DNA and common ancestry.[1] Throughout most of the history of science from Aristotle to Linnaeus and into the 20th century, species were divided into two kingdoms: animals and plants. Driven by DNA characterizations and other modern analysis, fungi and bacteria have now been removed to separate kingdoms; in particular,... More »
Horticulture Last Updated on 2014-09-08 22:22:03   Horticulture [L. hortus: garden +cult(us): till] is the cultivation of flowers, fruit, vegetables, or ornamental plants; the science and art of cultivating such plants. In addition to plant cultivation, other elements of horticulture include floral arranging, landscape design, and landscape installation, as well as landscape architecture, landscape management, interiorscaping, golf course management and urban forestry. Botanical gardens and arboreta provide public access to display gardens, and often support research programs as well. Horticultural therapy is the use of horticulture in therapeutical situations, such as in assisted living centers or for disadvantaged children' s programs. Greenhouse usage ranks high among plant production systems in terms of technological usage. A large majority of greenhouse crops are grown in containers using modified... More »
