Medicago Lupulina
''Medicago lupulina'', commonly known as black medick, nonesuch, or hop clover, is a plant of dry grassland belonging to the legume or clover family. Plants of the genus ''Medicago'', or bur clovers, are closely related to the true clovers (''Trifolium'') and sweet clover (''Melilotus''). Like the true clovers, black medick has three leaflets and a small, yellow flower closely resembling those of lesser trefoil. Black medick belongs to the same genus as alfalfa. Names The generic name ''Medicago'' is derived, via Latin , from Ancient Greek () "Median", because alfalfa was believed to have been introduced from the region of Media (now in Iran) in antiquity. The specific name ''lupulina'' means "wolf-like", and refers to the hop, or willow-wolf. Its scientific name is a translation of the common name hop clover (or hop-clover), which is also used for several members of the genus ''Trifolium''. Also spelled "medic" or "meddick", the plant is known by a number of alternate names, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grassland
A grassland is an area where the vegetation is dominance (ecology), dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes such as clover, and other Herbaceous plant, herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on Earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area. Definitions Included among the variety of definitions for grasslands are: * "...any plant community, including harvested forages, in which grasses and/or legumes make up the dominant vegetation." * "...terrestrial ecosystems dominated by herbaceous and shrub vegetation, and maintained by fire, grazing, drought and/or freezing temperatures."

Flora Of Lebanon
The flora of Lebanon includes approximately 2,600 plant species. Situated on the eastern coast of the Mediterranean Basin, Lebanon is a reservoir of plant diversity and one of the world's biodiversity hotspots for conservation priorities. Endemic species constitute 12% of the Lebanese flora; 221 plant species are broad endemics and 90 are narrow endemics.. Important Plant Areas (IPAs) featuring the country exceptional botanical richness were defined in 2018. The natural vegetation of Lebanon has been threatened by overexploitation and fragmentation as a result of urban expansion, overgrazing, tourism and the impact of warfare. The cedar of Lebanon is the national symbol of the country; growing in the Lebanon Mountain range, these trees have been heavily harvested over the years for their valuable timber and few mature trees still remain. Nevertheless, Lebanon is more heavily wooded than most other countries in the region and pine, oak, fir, beech, cypress and juniper are to be fo ...

Correspondence Of Charles Darwin
The British naturalist Charles Darwin corresponded with his extended family and with an extraordinarily wide range of people from all over the world. The letters, over 15,000 in all, provide many insights on issues ranging from the origins of key scientific concepts, to religious and philosophical discussions which have continued to the present day. The letters also illuminate many aspects of Darwin and his biography: the development of his ideas; insights into character and health; and private opinions on controversial issues. His letters to the Harvard botanist Asa Gray, for example, show his opinions on slavery and the American Civil War. Darwin relied upon correspondence for much of his scientific work, and also used letters to marshal support for his ideas amongst friends and colleagues. The historian of science Janet Browne has argued that Darwin's ability to correspond daily played a crucial role in the development of his theory and his ability to garner support for it fr ...

Nitrogen
Nitrogen is a chemical element; it has Symbol (chemistry), symbol N and atomic number 7. Nitrogen is a Nonmetal (chemistry), nonmetal and the lightest member of pnictogen, group 15 of the periodic table, often called the Pnictogen, pnictogens. It is a common element in the universe, estimated at Abundance of the chemical elements, seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element chemical bond, bond to form N2, a colourless and odourless diatomic molecule, diatomic gas. N2 forms about 78% of Atmosphere of Earth, Earth's atmosphere, making it the most abundant chemical species in air. Because of the volatility of nitrogen compounds, nitrogen is relatively rare in the solid parts of the Earth. It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772 and independently by Carl Wilhelm Scheele and Henry Cavendish at about the same time. The name was suggested by French chemist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fodder
Fodder (), also called provender (), is any agriculture, agricultural foodstuff used specifically to feed domesticated livestock, such as cattle, domestic rabbit, rabbits, sheep, horses, chickens and pigs. "Fodder" refers particularly to food given to the animals (including plants cut and carried to them), rather than that which they forage for themselves (called forage). Fodder includes hay, straw, silage, compressed and Compound feed, pelleted feeds, oils and mixed rations, and sprouting, sprouted grains and legumes (such as bean sprouts, fresh malt, or brewing#Brewer's spent grain, spent malt). Most animal feed is from plants, but some manufacturers add ingredients to processed feeds that are of animal origin. The worldwide animal feed trade produced 1.245 billion tons of compound feed in 2022 according to an estimate by the International Feed Industry Federation, with an annual growth rate of about 2%. The use of agricultural land to grow feed rather than human food can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Honey
Honey is a sweet and viscous substance made by several species of bees, the best-known of which are honey bees. Honey is made and stored to nourish bee colonies. Bees produce honey by gathering and then refining the sugary secretions of plants (primarily floral nectar) or the secretions of other insects, like the honeydew of aphids. This refinement takes place both within individual bees, through regurgitation and enzymatic activity, and during storage in the hive, through water evaporation that concentrates the honey's sugars until it is thick and viscous. Honey bees stockpile honey in the hive. Within the hive is a structure made from wax called honeycomb. The honeycomb is made up of hundreds or thousands of hexagonal cells, into which the bees regurgitate honey for storage. Other honey-producing species of bee store the substance in different structures, such as the pots made of wax and resin used by the stingless bee. Honey for human consumption is collected ...
