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 pla ...

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be separated from Asia by the watershed of the Ural Mountains, the Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Blac ...

Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present.

Flora
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring (indigenous (ecology), indigenous) native plant, native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora (mythology), Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic compos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juncus Subnodulosus
''Juncus subnodulosus'', the blunt-flowered rush, is a species of rush. It natively occurs from the Mediterranean region across temperate Europe, but it does not range far into Scandinavia. Introduced populations exist in New Zealand and North America. This species is an important associate within the anthropogenic Anthropogenic ("human" + "generating") is an adjective that may refer to: * Anthropogeny, the study of the origins of humanity Counterintuitively, anthropogenic may also refer to things that have been generated by humans, as follows: * Human im ...

Cirsium Palustre
''Cirsium palustre'', the marsh thistle or European swamp thistle, is a herbaceous biennial (or often perennial) flowering plant in the family Asteraceae. ''Cirsium palustre'' is a tall thistle which reaches up to in height. The strong stems have few branches and are covered in small spines. In its first year the plant grows as a dense rosette, at first with narrow, entire leaves with spiny, dark purple edges; later, larger leaves are lobed. In the subsequent years the plant grows a tall, straight stem, the tip of which branches repeatedly, bearing a candelabra of dark purple flowers, with purple-tipped bracts. In the northern hemisphere these are produced from June to September. The flowers are occasionally white, in which case the purple edges to the leaves are absent. The plant provides a great deal of nectar for pollinators. It was rated first out of the top 10 for most nectar production (nectar per unit cover per year) in a UK plants survey conducted by the AgriLand ...

Filipendula Ulmaria
''Filipendula ulmaria'', commonly known as meadowsweet or mead wort, is a perennial herbaceous plant in the family Rosaceae that grows in damp meadows. It is native throughout most of Europe and Western Asia (Near east and Middle east). It has been introduced and naturalised in North America. Meadowsweet has also been referred to as queen of the meadow, pride of the meadow, meadow-wort, meadow queen, lady of the meadow, dollof, meadsweet, and bridewort. Description The stems, growing up to 120 cm, are tall, erect and furrowed, reddish to sometimes purple. The leaves are dark-green on the upper side and whitish and downy underneath, much divided, interruptedly pinnate, having a few large serrate leaflets and small intermediate ones. Terminal leaflets are large, 4–8 cm long, and three- to five-lobed. Meadowsweet has delicate, graceful, creamy-white flowers clustered close together in irregularly-branched cymes, having a very strong, sweet smell redolent of antisep ...

Equisetum Palustre
''Equisetum palustre'', the marsh horsetail, is a plant species belonging to the division of horsetails (Equisetopsida). It is widespread in cooler regions of North America and Eurasia. Description ''Equisetum palustre'' is a perennial cryptophyte, growing between 10 and 50 centimeters (4" to 20"), in rare cases up to one meter (3'). Its fertile shoots, which carry ears, are evergreen and shaped like the sterile shoots. The rough, furrowed stem is one to three mm in diameter with usually eight to ten ribs, in rare cases, four to 12. It contains whorled branches. The tight-fitting sheaths end in four to 12 teeth. The lower sheaths are dark brown and much shorter than the sheaths of the main shoot. The central and vallecular canals are about the same size, but the carinal channels are much smaller. The central channels measure about one sixth of the diameter of the stem. The spores are spread by the wind (anemochory) and have four long ribbon-like structures attached to them. ...

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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
