Lotus Pedunculatus
''Lotus pedunculatus'' (formerly ''Lotus uliginosus''), the big trefoil, greater bird's-foot-trefoil or marsh bird's-foot trefoil, is a member of the pea family (Fabaceae). It is a herbaceous perennial growing throughout Europe in damp, open locations. As one common name suggests, it is a larger plant than related '' Lotus'' species, growing tall, with leaflets long and broad. Five to twelve golden-yellow flowers long are borne in an umbel at the tip of the upright stem. Unlike related species, the stem is always hollow, and the sepals turn back at their tips – these sepal tips form a characteristic "green star" at the end of the flower bud. The peak flowering period in the United Kingdom is June and July. ''Lotus pedunculatus'' occurs in a wide range of neutral, damp, open habitats, including certain fen-meadow plant associations such as ''Juncus subnodulosus''-''Cirsium palustre'' fen-meadow habitat. ''Lotus pedunculatus'' is also a host plant for ovipositioning of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antonio José Cavanilles
Antonio José Cavanilles (16 January 1745 – 5 May 1804) was a leading Spanish taxonomic botanist of the 18th century. He named many plants, particularly from Oceania. He named at least 100 genera, about 54 of which were still used in 2004, including ''Dahlia'', '' Calycera'', ''Cobaea'', '' Galphimia'', and ''Oleandra''. Biography Cavanilles was born in Valencia. He lived in Paris from 1777 to 1781, where he followed careers as a clergyman and a botanist, thanks to André Thouin and Antoine Laurent de Jussieu. He was one of the first Spanish scientists to use the classification method invented by Carl Linnaeus. From Paris he moved to Madrid, where he was director of the Royal Botanical Garden and Professor of botany from 1801 to 1804. In 1804, Cavanilles was elected a member of the American Philosophical Society in Philadelphia. He died in Madrid in 1804.

Soil Acidity
Soil pH is a measure of the acidity or basicity (alkalinity) of a soil. Soil pH is a key characteristic that can be used to make informative analysis both qualitative and quantitatively regarding soil characteristics. pH is defined as the negative logarithm (base 10) of the activity of hydronium ions ( or, more precisely, ) in a solution. In soils, it is measured in a slurry of soil mixed with water (or a salt solution, such as ), and normally falls between 3 and 10, with 7 being neutral. Acid soils have a pH below 7 and alkaline soils have a pH above 7. Ultra-acidic soils (pH 9) are rare. Soil pH is considered a master variable in soils as it affects many chemical processes. It specifically affects plant nutrient availability by controlling the chemical forms of the different nutrients and influencing the chemical reactions they undergo. The optimum pH range for most plants is between 5.5 and 7.5; however, many plants have adapted to thrive at pH values out ...

International Standard Serial Number
An International Standard Serial Number (ISSN) is an eight-digit serial number used to uniquely identify a serial publication, such as a magazine. The ISSN is especially helpful in distinguishing between serials with the same title. ISSNs are used in ordering, cataloging, interlibrary loans, and other practices in connection with serial literature. The ISSN system was first drafted as an International Organization for Standardization (ISO) international standard in 1971 and published as ISO 3297 in 1975. ISO subcommittee TC 46/SC 9 is responsible for maintaining the standard. When a serial with the same content is published in more than one media type, a different ISSN is assigned to each media type. For example, many serials are published both in print and electronic media. The ISSN system refers to these types as print ISSN (p-ISSN) and electronic ISSN (e-ISSN). Consequently, as defined in ISO 3297:2007, every serial in the ISSN system is also assigned a linking ISSN ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Object Identifier
A digital object identifier (DOI) is a persistent identifier or handle used to uniquely identify various objects, standardized by the International Organization for Standardization (ISO). DOIs are an implementation of the Handle System; they also fit within the URI system ( Uniform Resource Identifier). They are widely used to identify academic, professional, and government information, such as journal articles, research reports, data sets, and official publications. DOIs have also been used to identify other types of information resources, such as commercial videos. A DOI aims to resolve to its target, the information object to which the DOI refers. This is achieved by binding the DOI to metadata about the object, such as a URL where the object is located. Thus, by being actionable and interoperable, a DOI differs from ISBNs or ISRCs which are identifiers only. The DOI system uses the indecs Content Model for representing metadata. The DOI for a document remains fixed over t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leptidea Sinapis
''Leptidea sinapis,'' or the wood white butterfly of the family Pieridae, is a small white butterfly that is mainly found in England, Ireland, and Northern Europe. The butterfly has white wings with grey or yellow markings near the center or tip of the wing. It flies slowly and low over its shrubbery habitat. Males initiate courtship with females and can mate multiply, while females tend to only mate once in their lifetime. The wood white was added to the UK BAP Priority Species list in 2005 due to a substantial decline in the population, especially in England. This decline has been attributed to changes in woodland regions, including increased shade due to tree planting, and the failure to maintain woodland rides in a satisfactory way for wood whites to oviposit. Conservation efforts are currently striving to understand how to best maintain woodland regions and are examining the effect of climate change (particularly during the winter months) on egg survival.

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juncus Subnodulosus-Cirsium Palustre Fen-meadow
''Juncus'' is a genus of monocotyledonous flowering plants, commonly known as rushes. It is the largest genus in the family Juncaceae, containing around 300 species. Description Rushes of the genus ''Juncus'' are herbaceous plant, herbaceous plants that superficially resemble Poaceae, grasses or sedges. They have historically received little attention from botanists; in his 1819 monograph, James Ebenezer Bicheno described the genus as "obscure and uninviting". The form of the flower differentiates rushes from grasses or sedges. The flowers of ''Juncus'' comprise five whorl (botany), whorls of floral parts: three sepals, three petals (or, taken together, six tepals), two to six stamens (in two whorls) and a stigma (botany), stigma with three lobes. The stems are round in cross-section, unlike those of sedges, which are typically somewhat triangular in cross-section. In ''Juncus'' section ''Juncotypus'' (formerly called ''Juncus'' subg. ''Genuini''), which contains some of the mos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Association
A plant community is a collection or association of plant species within a designated geographical unit, which forms a relatively uniform patch, distinguishable from neighboring patches of different vegetation types. The components of each plant community are influenced by soil type, topography, climate and human disturbance. In many cases there are several soil types present within a given plant community. This is because the soil type within an area is influenced by two factors, the rate at which water infiltrates or exits (via evapotranspiration) the soil, as well as the rate at which organic matter (any carbon-based compound within the environment, such as decaying plant matter) enters or decays from the soil. Plant communities are studied substantially by ecologists, due to providing information on the effects of dispersal, tolerance to environmental conditions, and response to disturbance of a variety of plant species, information valuable to the comprehension of various plant ...

Fen-meadow
A fen-meadow is a type of peatland, common in North America and Europe, that receives water from precipitation and groundwater. Habitat The continuous flow of mineral-rich and nutrient-poor acidic groundwater through fen-meadow topsoil fosters endemic plant species, including plant associations such as '' Juncus subnodulosus-Cirsium palustre'', and protects them from floods, droughts, and nutrient pollution. Degradation by human activity Fen meadows have been severely impacted by farming, resulting in hydrological changes, acidification, and nutrient pollution, leaving few preserved into the 21st century. Compositional transformations and increased groundwater flow have the greatest effect this habitat and can degrade peat. Keeping water tables at appropriate levels allows fen meadows to regulate themselves. Restoration efforts are difficult and no deteriorated fens have been fully restored. Therefore, preservation efforts focus on maintaining fen meadows with slight to no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United Kingdom
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Europe, off the north-western coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, and many smaller islands within the British Isles.
