Sanguisorba Minor
''Sanguisorba minor'', the salad burnet, garden burnet, small burnet, burnet (also used for ''Sanguisorba'' generally), pimpernelle, Toper's plant, and burnet-bloodwort, is an edible perennial herbaceous plant in the family Rosaceae. It has ferny, toothed-leaf foliage; the unusual crimson, spherical flower clusters rise well above the leaves on thin stems. It generally grows to 25–55 cm tall (moisture-dependent; as short as 2 cm in dry areas). The large, long (sometimes 1m/3-foot), taproots store water, making it drought-tolerant. It is evergreen to semi-evergreen; in warmer climates grows all year around, and in cold climates it stays green until heavy snow cover occurs. Plants may live over 20 years, though 7-12 is more usual; it lives longer if sometimes permitted to set seed. Burnet flowers in early summer. Subspecies include ''muricata'', ''minor'', and ''mongolii'' (the last from the Mediterranean). Occurrence Salad burnet is native to western, central and ...

Giovanni Antonio Scopoli
Giovanni Antonio Scopoli (sometimes Latinisation of names, Latinized as Johannes Antonius Scopolius) (3 June 1723 – 8 May 1788) was an Italian physician and natural history, naturalist. His biographer Otto Guglia named him the "first anational European" and the "Carl Linnaeus, Linnaeus of the Austrian Empire". Biography Scopoli was born at Cavalese in the Val di Fiemme, belonging to the Prince-Bishopric of Trent, Bishopric of Trent (today's Trentino), son of Francesco Antonio, military commissioner, and Claudia Caterina Gramola (1699-1791), painter from a patrician family from Trentino. He obtained a degree in medicine at University of Innsbruck, and practiced as a doctor in Cavalese and Venice.Newton, Alfred 1881. ''Scopoli's ornithological papers.''

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monoecious
Monoecy (; adj. monoecious ) is a sexual system in seed plants where separate male and female cones or flowers are present on the same plant. It is a monomorphic sexual system alongside gynomonoecy, andromonoecy and trimonoecy. Monoecy is connected to anemophily. It can prevent self-pollination in an individual flower but cannot prevent self-pollination between male and female flowers on the same plant. Monoecy in angiosperms has been of interest for evolutionary biologists since Charles Darwin. Terminology Monoecious comes from the Greek words for one house. History The term monoecy was first introduced in 1735 by Carl Linnaeus. Darwin noted that the flowers of monoecious species sometimes showed traces of the opposite sex function. Monoecious hemp was first reported in 1929. Occurrence Monoecy is most common in temperate climates and is often associated with inefficient pollinators or wind-pollinated plants. It may be beneficial to reducing pollen-stigma interferenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Firebreak
A firebreak or double track (also called a fire line, fuel break, fireroad and firetrail in Australia) is a gap in vegetation or other combustible material that acts as a barrier to slow or stop the progress of a bushfire or wildfire. A firebreak may occur naturally where there is a lack of vegetation or "fuel", such as a river, lake or canyon. Firebreaks may also be man-made, and many of these also serve as roads, such as a logging road, four-wheel drive trail, secondary road, or a highway. Overview In the construction of a firebreak, the primary goal is to remove deadwood and undergrowth down to mineral soil. Various methods may be used to accomplish this initially and to maintain this condition. Ideally, the firebreak will be constructed and maintained according to the established practices of sustainable forestry and fire protection engineering, also known as best management practices (BMP). The general goals are to maximize the effectiveness of the firebreak at slowing th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rangeland
Rangelands are grasslands, shrublands, woodlands, wetlands, and deserts that are grazed by domestic livestock or wild animals. Types of rangelands include tallgrass and shortgrass prairies, desert grasslands and shrublands, woodlands, savannas, chaparrals, steppes, and tundras. Rangelands do not include forests lacking grazable understory vegetation, barren desert, farmland, or land covered by solid rock, concrete and/or glaciers. Rangelands are distinguished from pasture lands because they grow primarily native vegetation, rather than plants established by humans. Rangelands are also managed principally with practices such as managed livestock grazing and prescribed fire rather than more intensive agricultural practices of seeding, irrigation, and the use of fertilizers. Grazing is an important use of rangelands but the term ''rangeland'' is not synonymous with ''grazingland''. Livestock grazing can be used to manage rangelands by harvesting forage to produce livestock, cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kitchen Garden
The traditional kitchen garden, vegetable garden, also known as a potager (from the French ) or in Scotland a kailyaird, is a space separate from the rest of the residential garden – the ornamental plants and lawn areas. It is used for growing edible plants and often some medicinal plants, especially historically. The plants are grown for domestic use; though some seasonal surpluses are given away or sold, a commercial operation growing a variety of vegetables is more commonly termed a market garden (or a farm). The kitchen garden is different not only in its history, but also its functional design. It differs from an allotment in that a kitchen garden is on private land attached or very close to the dwelling. It is regarded as essential that the kitchen garden could be quickly accessed by the cook. Historically, most small country gardens were probably mainly or entirely used as kitchen gardens, but in large country houses the kitchen garden was a segregated area, nor ...

Wildflower Meadow
A wildflower (or wild flower) is a flower that grows in the wild, meaning it was not intentionally seeded or planted. The term implies that the plant probably is neither a hybrid nor a selected cultivar that is in any way different from the way it appears in the wild as a native plant, even if it is growing where it would not naturally. The term can refer to the flowering plant as a whole, even when not in bloom, and not just the flower. "Wildflower" is not an exact term. More precise terms include ''native species'' (naturally occurring in the area, see flora), ''exotic'' or, better, ''introduced species'' (not naturally occurring in the area), of which some are labelled ''invasive species'' (that out-compete other plants – whether native or not), ''imported'' (introduced to an area whether deliberately or accidentally) and ''naturalized'' (introduced to an area, but now considered by the public as native). In the United Kingdom, the organization Plantlife International in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hardiness Zone
A hardiness zone is a geographic area defined as having a certain average annual minimum temperature, a factor relevant to the survival of many plants. In some systems other statistics are included in the calculations. The original and most widely used system, developed by the United States Department of Agriculture (USDA) as a rough guide for landscaping and gardening, defines 13 zones by long-term average annual extreme minimum temperatures. It has been adapted by and to other countries (such as Canada) in various forms. Unless otherwise specified, in American contexts "hardiness zone" or simply "zone" usually refers to the USDA scale. For example, a plant may be described as "hardy to zone 10": this means that the plant can withstand a minimum temperature of 30 °F (−1.1 °C) to 40 °F (4.4 °C). Other hardiness rating schemes have been developed as well, such as the UK Royal Horticultural Society and US Sunset Western Garden Book systems. A heat zone (s ...

Founder Effect
In population genetics, the founder effect is the loss of genetic variation that occurs when a new population is established by a very small number of individuals from a larger population. It was first fully outlined by Ernst Mayr in 1942, using existing theoretical work by those such as Sewall Wright. As a result of the loss of genetic variation, the new population may be distinctively different, both genotypically and phenotypically, from the parent population from which it is derived. In extreme cases, the founder effect is thought to lead to the speciation and subsequent evolution of new species. In the figure shown, the original population has nearly equal numbers of blue and red individuals. The three smaller founder populations show that one or the other color may predominate (founder effect), due to random sampling of the original population. A population bottleneck may also cause a founder effect, though it is not strictly a new population. The founder effect occurs wh ...

Garrigue
Garrigue or garigue ( ), also known as phrygana ( el, φρύγανα , n. pl.), is a type of low scrubland ecoregion and plant community in the Mediterranean forests, woodlands, and scrub biome. It is found on limestone soils in southern France and around the Mediterranean Basin, generally near the seacoast where the moderated Mediterranean climate provides annual summer drought. It is an anthropogenic degradation and succession form of former evergreen oak forests that existed until 4500 years BC. The term has also found its way into haute cuisine, suggestive of the resinous flavours of a garrigue shrubland. Habitat and vegetation UNEP World Conservation Monitoring Centre described garrigue as "discontinuous bushy associations of the Mediterranean calcareous plateaus, which have relatively alkaline soils. It is often composed of kermes oak, lavender, thyme, and white cistus. There may be a few isolated trees." Garrigue is discontinuous with widely spaced bush associati ...
