Quercus Ilex
''Quercus ilex'', the evergreen oak, holly oak or holm oak is a large evergreen oak native to the Mediterranean region. It is a member of the '' Ilex'' section of the genus, with acorns that mature in a single summer. Description An evergreen tree of large size, attaining in favourable places a height of , and developing in open situations a huge head of densely leafy branches as much across, the terminal portions of the branches usually pendulous in old trees. The trunk is sometimes over in girth. The young shoots are clothed with a close gray felt. The leaves are very variable in shape, most frequently narrowly oval or ovate-lanceolate, long, 1.2–2.5 cm wide, rounded or broadly tapered at the base, pointed, the margins sometimes entire, sometimes (especially on young trees) more or less remotely toothed. When quite young, both surfaces are clothed with whitish down, which soon falls away entirely from the upper surface leaving it a dark glossy green; on the l ...

Quercus Rotundifolia
''Quercus rotundifolia'', the holm oak or ballota oak, is an evergreen oak native to the western Mediterranean region, with the majority on the Iberian Peninsula and minor populations in Northwest Africa. The species was first described by Jean-Baptiste Lamarck in 1785. It is the typical species of the Iberian '' dehesa'' or ''montado'', where its sweet-astringent acorns are a source of food for livestock, particularly the Iberian pig. It has previously been described in the same species as ''Quercus ilex''. Its acorns have been used for human nourishment since the Neolithic era (7,000 BC). Description ''Quercus rotundifolia'' is a medium to large tree, usually in height, but can reach up to with a large, dense, rounded canopy. It has small, leathery, dark-green leaves with a glaucous, densely pubescent underside usually suborbicular to elliptical or lanceolate and are generally spiny to dentate on a younger tree. It has a semi-hemispheric cupule. It flowers from Febru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his Nobility#Ennoblement, ennoblement in 1761 as Carl von Linné#Blunt, Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In ...

Hedge (gardening)
A hedge or hedgerow is a line of closely spaced shrubs and sometimes trees, planted and trained to form a barrier or to mark the boundary of an area, such as between neighbouring properties. Hedges that are used to separate a road from adjoining fields or one field from another, and are of sufficient age to incorporate larger trees, are known as hedgerows. Often they serve as windbreaks to improve conditions for the adjacent crops, as in bocage country. When clipped and maintained, hedges are also a simple form of topiary. A hedge often operates as, and sometimes is called, a "live fence". This may either consist of individual fence posts connected with wire or other fencing material, or it may be in the form of densely planted hedges without interconnecting wire. This is common in tropical areas where low-income farmers can demarcate properties and reduce maintenance of fence posts that otherwise deteriorate rapidly. Many other benefits can be obtained depending on the spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ectomycorrhizal
An ectomycorrhiza (from Greek ἐκτός ', "outside", μύκης ', "fungus", and ῥίζα ', "root"; pl. ectomycorrhizas or ectomycorrhizae, abbreviated EcM) is a form of symbiotic relationship that occurs between a fungal symbiont, or mycobiont, and the roots of various plant species. The mycobiont is often from the phyla Basidiomycota and Ascomycota, and more rarely from the Zygomycota. Ectomycorrhizas form on the roots of around 2% of plant species, usually woody plants, including species from the birch, dipterocarp, myrtle, beech, willow, pine and rose families. Research on ectomycorrhizas is increasingly important in areas such as ecosystem management and restoration, forestry and agriculture. Unlike other mycorrhizal relationships, such as arbuscular mycorrhiza and ericoid mycorrhiza, ectomycorrhizal fungi do not penetrate their host's cell walls. Instead they form an entirely intercellular interface known as the Hartig net, consisting of highly branche ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Truffle
A truffle is the fruiting body of a subterranean ascomycete fungus, predominantly one of the many species of the genus ''Tuber''. In addition to ''Tuber'', many other genera of fungi are classified as truffles including '' Geopora'', '' Peziza'', '' Choiromyces'', '' Leucangium'', and over a hundred others. These genera belong to the class Pezizomycetes and the Pezizales order. Several truffle-like basidiomycetes are excluded from Pezizales, including ''Rhizopogon'' and ''Glomus''. Truffles are ectomycorrhizal fungi, so they are usually found in close association with tree roots. Spore dispersal is accomplished through fungivores, animals that eat fungi. These fungi have significant ecological roles in nutrient cycling and drought tolerance. Some truffle species are highly prized as food. French gastronome Jean Anthelme Brillat-Savarin called truffles "the diamond of the kitchen". Edible truffles are used in Italian, French and numerous other national . Truffles are ...

Charcoal
Charcoal is a lightweight black carbon residue produced by strongly heating wood (or other animal and plant materials) in minimal oxygen to remove all water and volatile constituents. In the traditional version of this pyrolysis process, called charcoal burning, often by forming a charcoal kiln, the heat is supplied by burning part of the starting material itself, with a limited supply of oxygen. The material can also be heated in a closed retort. Modern "charcoal" briquettes used for outdoor cooking may contain many other additives, e.g. coal. This process happens naturally when combustion is incomplete, and is sometimes used in radiocarbon dating. It also happens inadvertently while burning wood, as in a fireplace or wood stove. The visible flame in these is due to combustion of the volatile gases exuded as the wood turns into charcoal. The soot and smoke commonly given off by wood fires result from incomplete combustion of those volatiles. Charcoal burns at a highe ...

Works And Days
''Works and Days'' ( grc, Ἔργα καὶ Ἡμέραι, Érga kaì Hēmérai)The ''Works and Days'' is sometimes called by the Latin translation of the title, ''Opera et Dies''. Common abbreviations are ''WD'' and ''Op''. for ''Opera''. is a didactic poem written by the ancient Greek poet Hesiod around 700 BC. It is in dactylic hexameter and contains 828 lines. At its center, the ''Works and Days'' is a farmer's almanac in which Hesiod instructs his brother Perses in the agricultural arts. Scholars have seen this work against a background of agrarian crisis in mainland Greece, which inspired a wave of colonial expeditions in search of new land. In the poem, Hesiod also offers his brother extensive moralizing advice on how he should live his life. ''Works and Days'' is perhaps best known for its two mythological aetiologies for the toil and pain that define the human condition: the story of Prometheus and Pandora, and the so-called Myth of Five Ages.

Hesiod
Hesiod (; grc-gre, Ἡσίοδος ''Hēsíodos'') was an ancient Greek poet generally thought to have been active between 750 and 650 BC, around the same time as Homer. He is generally regarded by western authors as 'the first written poet in the Western tradition to regard himself as an individual persona with an active role to play in his subject.' Ancient authors credited Hesiod and Homer with establishing Greek religious customs. Modern scholars refer to him as a major source on Greek mythology, farming techniques, early economic thought, archaic Greek astronomy and ancient time-keeping. Life The dating of Hesiod's life is a contested issue in scholarly circles (''see § Dating below''). Epic narrative allowed poets like Homer no opportunity for personal revelations. However, Hesiod's extant work comprises several didactic poems in which he went out of his way to let his audience in on a few details of his life. There are three explicit references in '' Works and Da ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wood
Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or woodchips or fiber. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper. More recently it emerged as a feedstock for the ...

National Trust
The National Trust, formally the National Trust for Places of Historic Interest or Natural Beauty, is a charity and membership organisation for heritage conservation in England, Wales and Northern Ireland. In Scotland, there is a separate and independent National Trust for Scotland. The Trust was founded in 1895 by Octavia Hill, Sir Robert Hunter and Hardwicke Rawnsley to "promote the permanent preservation for the benefit of the Nation of lands and tenements (including buildings) of beauty or historic interest". It was given statutory powers, starting with the National Trust Act 1907. Historically, the Trust acquired land by gift and sometimes by public subscription and appeal, but after World War II the loss of country houses resulted in many such properties being acquired either by gift from the former owners or through the National Land Fund. Country houses and estates still make up a significant part of its holdings, but it is also known for its protection of wild la ...

Eurasian Jay
The Eurasian jay (''Garrulus glandarius'') is a species of passerine bird in the crow family Corvidae. It has pinkish brown plumage with a black stripe on each side of a whitish throat, a bright blue panel on the upper wing and a black tail. The Eurasian jay is a woodland bird that occurs over a vast region from western Europe and north-west Africa to the Indian subcontinent and further to the eastern seaboard of Asia and down into south-east Asia. Across this vast range, several distinct racial forms have evolved which look different from each other, especially when comparing forms at the extremes of its range. The bird is called jay, without any epithets, by English speakers in Great Britain and Ireland. Taxonomy and systematics The Eurasian jay was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Corvus glandarius''. Linnaeus specified the locality as "Europa" but this was restr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
