Quercus Ithaburensis
''Quercus ithaburensis'', the Mount Tabor oak, is a tree in the beech family. It is found in Southeastern Europe, from southeastern Italy, southern Albania and Greece, and in southwestern Asia from Turkey south through Lebanon, Israel, Syria, and neighboring Jordan, whose national tree it is. Together with Quercus macrolepsis and Quercus brantii, it forms a clade of distinct, closely related species within the oak section ''Cerris''. ''Quercus ithaburensis'' is a small to medium-sized semi-evergreen to tardily deciduous tree growing to a maximum height of around with a rounded crown and often with a gnarled trunk and branches. The leaves are long and 2–5 cm wide, oval in shape, with 7 to 10 pairs of either teeth (most common) or shallow lobes (rare) along a revolute margin. They are dark glossy green above and gray tomentose below. The male flowers are light green 5-cm long catkins while the wind-pollinated female flowers are small, up to , produced in threes on shor ...

Joseph Decaisne
Joseph Decaisne (7 March 1807 – 8 January 1882) was a French botanist and agronomist. He became an ''aide-naturaliste'' to Adrien-Henri de Jussieu (1797-1853), who served as the chair of rural botany. It was during this time that he began to study plants brought back by various travelers like those of Victor Jacquemont (1801-1832) from Asia. Decaisne used applied research, most notably on the agronomy of the Rubia tinctorum, madder, the Yam (vegetable), yam and the ramie. He was also interested in algae. Biography Although born in Brussels, Belgium, he exercised his activity exclusively in Paris. He entered in 1824 as a gardener at the ''Muséum national d'histoire naturelle'' (French museum of natural history) and became, in 1832, head of the ''carré des semis'' section. He also worked at the ''Jardin des Plantes'' and collaborated with Asa Gray. In 1847 he chaired Statistical Agriculture department in the College de France. In 1850, Decaisne followed Charles-François Brisse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semi-evergreen
Semi-deciduous or semi-evergreen is a botanical term which refers to plants that lose their foliage for a very short period, when old leaves fall off and new foliage growth is starting. This phenomenon occurs in tropical and sub-tropical woody species, for example in Dipteryx odorata. Semi-deciduous or semi-evergreen may also describe some trees, bushes or plants that normally only lose part of their foliage in autumn/winter or during the dry season, but might lose all their leaves in a manner similar to deciduous trees in an especially cold autumn/winter or severe dry season (drought). See also * Brevideciduous * Evergreen * Marcescence * Hedera ''Hedera'', commonly called ivy (plural ivies), is a genus of 12–15 species of evergreen climbing or ground-creeping woody plants in the family Araliaceae, native to western, central and southern Europe, Macaronesia, northwestern Africa an ...

Pasture
Pasture (from the Latin ''pastus'', past participle of ''pascere'', "to feed") is land used for grazing. Pasture lands in the narrow sense are enclosed tracts of farmland, grazed by domesticated livestock, such as horses, cattle, sheep, or swine. The vegetation of tended pasture, forage, consists mainly of grasses, with an interspersion of legumes and other forbs (non-grass herbaceous plants). Pasture is typically grazed throughout the summer, in contrast to meadow which is ungrazed or used for grazing only after being mown to make hay for animal fodder. Pasture in a wider sense additionally includes rangelands, other unenclosed pastoral systems, and land types used by wild animals for grazing or browsing. Pasture lands in the narrow sense are distinguished from rangelands by being managed through more intensive agricultural practices of seeding, irrigation, and the use of fertilizers, while rangelands grow primarily native vegetation, managed with extensive practices like co ...

Ra'anana
Ra'anana ( he, רַעֲנָנָּה, lit. "Fresh") is a city in the southern Sharon Plain of the Central District of Israel. It was founded in 1922 as an American-Jewish settlement, 1 km south of the village of Tabsur, where an important World War I battle had taken place four years previously. Bordered by Kfar Saba and Hod HaSharon on the east and Herzliya on the southwest, it had a population of in . While the majority of its residents are native-born Israeli Jews, a large part of the population consists of Jewish immigrants from the Americas and Europe. Ra'anana's industrial park, built over the depopulated village of Tabsur, is home to global and local start-up companies. It was designated a "Green City" by the World Health Organization in 2005. History In 1912, the Company for Jewish Settlement in Israel formed the "Ahuza A – New York" group to purchase land in Palestine for agricultural settlement. World War I delayed their plans, but in 1921, it was decid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Woodland
A woodland () is, in the broad sense, land covered with trees, or in a narrow sense, synonymous with wood (or in the U.S., the ''plurale tantum'' woods), a low-density forest forming open habitats with plenty of sunlight and limited shade (see differences between British, American, and Australian English explained below). Woodlands may support an understory of shrubs and herbaceous plants including grasses. Woodland may form a transition to shrubland under drier conditions or during early stages of primary or secondary succession. Higher-density areas of trees with a largely closed canopy that provides extensive and nearly continuous shade are often referred to as forests. Extensive efforts by conservationist groups have been made to preserve woodlands from urbanization and agriculture. For example, the woodlands of Northwest Indiana have been preserved as part of the Indiana Dunes. Definitions United Kingdom ''Woodland'' is used in British woodland management to mean tre ...

Sharon Plain
The Sharon plain ( ''HaSharon Arabic: سهل شارون Sahel Sharon'') is the central section of the Israeli coastal plain. The plain lies between the Mediterranean Sea to the west and the Samarian Hills, to the east. It stretches from Nahal Taninim, a stream marking the southern end of Mount Carmel in the north, to the Yarkon River in the south, at the northern limit of Tel Aviv, over a total of about . The level of the Sharon plain is connected to the level of the Mediterranean Sea by the Sharon Escarpment. Parts of the Plain are included in the Central, Haifa and Tel Aviv Districts of Israel. History Early The Sharon valley is mentioned in an ancient Egyptian stele of Amenhotep II, and as the Sharon field containing both Jaffa and Dor on the Eshmunazar II sarcophagus. The Plain of Sharon is mentioned in the Bible ( 1 Chronicles 5:16, 27:29; Book of Isaiah 33:9, 35:2, 65:10), including the famous reference to the enigmatic "Rose of Sharon" ( Song of Songs 2:1). ...

20th Century
The 20th (twentieth) century began on January 1, 1901 ( MCMI), and ended on December 31, 2000 ( MM). The 20th century was dominated by significant events that defined the modern era: Spanish flu pandemic, World War I and World War II, nuclear weapons, nuclear power and space exploration, nationalism and decolonization, technological advances, and the Cold War and post-Cold War conflicts. These reshaped the political and social structure of the globe. The 20th century saw a massive transformation of humanity's relationship with the natural world. Global population, sea level rise, and ecological collapses increased while competition for land and dwindling resources accelerated deforestation, water depletion, and the mass extinction of many of the world's species and decline in the population of others. Global heating increased the risk of extreme weather conditions. Additional themes include intergovernmental organizations and cultural homogenization through developments in em ...

Acorn
The acorn, or oaknut, is the nut of the oaks and their close relatives (genera ''Quercus'' and '' Lithocarpus'', in the family Fagaceae). It usually contains one seed (occasionally two seeds), enclosed in a tough, leathery shell, and borne in a cup-shaped cupule. Acorns are long and on the fat side. Acorns take between 5 and 24 months (depending on the species) to mature; see the list of ''Quercus'' species for details of oak classification, in which acorn morphology and phenology are important factors. Etymology The word ''acorn'' (earlier ''akerne'', and ''acharn'') is related to the Gothic name ''akran'', which had the sense of "fruit of the unenclosed land". The word was applied to the most important forest produce, that of the oak. Chaucer spoke of "achornes of okes" in the 14th century. By degrees, popular etymology connected the word both with "corn" and "oak-horn", and the spelling changed accordingly. The current spelling (emerged 15c.-16c.), derives from asso ...

Peduncle (botany)
In botany, a peduncle is a stalk supporting an inflorescence or a solitary flower, or, after fecundation, an infructescence or a solitary fruit. The peduncle sometimes has bracts (a type of cataphylls) at nodes. The main axis of an inflorescence above the peduncle is the rachis. There are no flowers on the peduncle but there are flowers on the rachis. When a peduncle arises from the ground level, either from a compressed aerial stem or from a subterranean stem (rhizome, tuber, bulb, corm), with few or no bracts except the part near the rachis or receptacle, it is referred to as a scape. The acorns of the pedunculate oak are borne on a long peduncle, hence the name of the tree. See also *Pedicel (botany) *Scape (botany) In botany, a scape is a peduncle arising from a subterranean or very compressed stem, with the lower internodes very long and hence few or no bracts except the part near the rachis or receptacle. Typically it takes the form of a long, leafles ... Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catkins
A catkin or ament is a slim, cylindrical flower cluster (a spike), with inconspicuous or no petals, usually wind-pollinated (anemophilous) but sometimes insect-pollinated (as in ''Salix''). They contain many, usually unisexual flowers, arranged closely along a central stem that is often drooping. They are found in many plant families, including Betulaceae, Fagaceae, Moraceae, and Salicaceae. Occurrence Catkin-bearing plants include many trees or shrubs such as birch, willow, aspen, hickory, sweet chestnut, and sweetfern (''Comptonia''). In many of these plants, only the male flowers form catkins, and the female flowers are single (hazel, oak), a cone (alder), or other types (mulberry). In other plants (such as poplar), both male and female flowers are borne in catkins. In Britain, they can be seen in January or February, when many trees are bare for winter. They can even occur in December. Evolution For some time, catkins were believed to be a key synapomorphy among the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tomentose
Trichomes (); ) are fine outgrowths or appendages on plants, algae, lichens, and certain protists. They are of diverse structure and function. Examples are hairs, glandular hairs, scales, and papillae. A covering of any kind of hair on a plant is an indumentum, and the surface bearing them is said to be pubescent. Algal trichomes Certain, usually filamentous, algae have the terminal cell produced into an elongate hair-like structure called a trichome. The same term is applied to such structures in some cyanobacteria, such as '' Spirulina'' and ''Oscillatoria''. The trichomes of cyanobacteria may be unsheathed, as in ''Oscillatoria'', or sheathed, as in ''Calothrix''. These structures play an important role in preventing soil erosion, particularly in cold desert climates. The filamentous sheaths form a persistent sticky network that helps maintain soil structure. Plant trichomes Plant trichomes have many different features that vary between both species of plants and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
