Arum Cylindraceum
''Arum cylindraceum'' is a woodland plant species of the family Araceae. It is found in most of Europe except the UK, Russia, Ukraine, Belarus, the Baltic States and Scandinavia (although it is found in Denmark), and in Turkey. It is also missing in northwestern France and southern Italy. Description The plain green leaves of ''A. cylindraceum'' appear in early spring (late March–early May) followed by the flowers borne on a poker-shaped inflorescence called a spadix, which is partially enclosed in a grass-green spathe or leaf-like hood. The flowers are hidden from sight, clustered at the base of the spadix with a ring of female flowers at the bottom and a ring of male flowers above them. Above the male flowers is a ring of hairs forming an insect trap. Insects are attracted to the spadix by its faecal odour and a temperature warmer than the ambient temperature. The insects are trapped beneath the ring of hairs and are dusted with pollen by the male flowers before escaping and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gasp
Paralanguage, also known as vocalics, is a component of meta-communication that may modify meaning, give nuanced meaning, or convey emotion, by using suprasegmental techniques such as prosody, pitch, volume, intonation, etc. It is sometimes defined as relating to nonphonemic properties only. Paralanguage may be expressed consciously or unconsciously. The study of paralanguage is known as paralinguistics and was invented by George L. Trager in the 1950s, while he was working at the Foreign Service Institute of the U.S. Department of State. His colleagues at the time included Henry Lee Smith, Charles F. Hockett (working with him on using descriptive linguistics as a model for paralanguage), Edward T. Hall developing proxemics, and Ray Birdwhistell developing kinesics. Trager published his conclusions in 1958, 1960 and 1961. His work has served as a basis for all later research, especially those investigating the relationship between paralanguage and culture (since paralang ...

Arum
''Arum'' is a genus of plants in the Araceae family; they are native to Europe, northern Africa, and western and central Asia, with the highest species diversity in the Mediterranean region. Frequently called arum lilies, they are not closely related to the true lilies ''Lilium''. Plants in the closely related genus '' Zantedeschia'' are also called 'arum lilies'. They are rhizomatous, herbaceous perennial plants growing to 20–60 cm tall, with sagittate (arrowhead-shaped) leaves 10–55 cm long. The flowers are produced in a spadix, surrounded by a 10–40 cm long, distinctively coloured spathe, which may be white, yellow, brown, or purple. Some species are scented, others not. The fruit is a cluster of bright orange or red berries. All parts of the plants, including the berries, are poisonous as they contain needle-shaped crystals of calcium oxalate. In spite of this, the plant has a history of culinary use among Arab peasants in Palestine who leached t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neurotoxins
Neurotoxins are toxins that are destructive to nerve tissue (causing neurotoxicity). Neurotoxins are an extensive class of exogenous chemical neurological insultsSpencer 2000 that can adversely affect function in both developing and mature nervous tissue.Olney 2002 The term can also be used to classify endogenous compounds, which, when abnormally contacted, can prove neurologically toxic. Though neurotoxins are often neurologically destructive, their ability to specifically target neural components is important in the study of nervous systems. Common examples of neurotoxins include lead, ethanol (drinking alcohol), glutamate,Choi 1987 nitric oxide, botulinum toxin (e.g. Botox), tetanus toxin,Simpson 1986 and tetrodotoxin. Some substances such as nitric oxide and glutamate are in fact essential for proper function of the body and only exert neurotoxic effects at excessive concentrations. Neurotoxins inhibit neuron control over ion concentrations across the cell membrane, or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Toxins
A toxin is a naturally occurring poison produced by metabolic activities of living cells or organisms. They occur especially as proteins, often conjugated. The term was first used by organic chemist Ludwig Brieger (1849–1919), derived from '' toxic''. Toxins can be small molecules, peptides, or proteins that are capable of causing disease on contact with or absorption by body tissues interacting with biological macromolecules such as enzymes or cellular receptors. They vary greatly in their toxicity, ranging from usually minor (such as a bee sting) to potentially fatal even at extremely low doses (such as botulinum toxin). Terminology Toxins are often distinguished from other chemical agents strictly based on their biological origin. Less strict understandings embrace naturally occurring inorganic toxins, such as arsenic. Other understandings embrace synthetic analogs of naturally occurring organic poisons as toxins, and may or may not embrace naturally oc ...

Flora Of Turkey
The flora of Turkey consists of almost 10,000 species of plants, as well as a number of fungi and algae. Around 32% of Turkey's plants are found only in the country. One reason for the high proportion of endemics is that Anatolia is both mountainous and quite fragmented. The country is divided into three main floristic areas: the Mediterranean, Euro-Siberian, and Irano-Tranian area. The flora of the European part of Turkey is similar to that of adjoining Greece. The ecoregions here include Balkan mixed forests dominated by Oak, oaks, and Aegean and Western Turkey sclerophyllous and mixed forests where some of the main species are oaks, Arbutus unedo, strawberry tree, ''Arbutus andrachne, Greek strawberry tree'', Spartium junceum, Spanish broom and Laurus nobilis, laurel.

Flora Of Sweden
Located in the Scandinavian Peninsula, Sweden is a mountainous country dominated by lakes and forests. Its habitats include mountain heath, montane forests, tundra, taiga, beech forests, rivers, lakes, bogs, brackish and marine coastal ecosystems, and cultivated land.

Flora Of Cyprus
The wildlife of Cyprus includes its flora and fauna and their natural habitats. Cyprus has a rich flora and a diverse fauna albeit with relatively few mammals. Like most modern countries, the natural habitats in Cyprus have been steadily disappearing, currently retaining only 20% of its original habitat due to rapid urbanization, usage of forests for commercial purposes, tourism and various other reasons. One of the features of Cyprus' habitats is the wild and sharp differences in elevations and habitats on the island as well as climate, all of which supply a diverse habitat for an array of fauna and flora. Terra Cypria was established as a trust in 1992 to conserve the Cypriot environment and its biodiversity. Fauna Amphibians The fauna of Cyprus has four amphibians. Birds Cyprus also has over 380 species of bird due to being on migration routes between Africa, Europe and western Asia including Eleonora's falcon (''Falco eleonorae''), flamingo and the imperial eagle (''Aq ...

Flora Of Corsica
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) 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'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of 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 composition of a community) wa ...
