Ficus Burtt-davyi
''Ficus burtt-davyi'' is a fig species endemic to Southern Africa, belonging to the Mulberry family of Moraceae. It grows in coastal and inland forests up to 1500m, from the vicinity of Mossel Bay in the Southern Cape to southern Mozambique - the forms growing on coastal dunes in the northern part of its range are salt tolerant and form low thickets on the margins of woodland. In the southern and eastern Cape forests the species becomes a strangler or liane, while when found on rocky outcrops and cliffs it usually develops into a rock-splitter. In its epiphytic form this species starts its life in the forks of tree branches, where an accumulation of organic debris aids germination and initial development. It sends down long, thin roots to reach soil and water below. The roots thicken and grow in number with the passage of time, and can eventually enclose the supporting tree, strangling and killing it, leaving the fig to stand alone with no competition for resources.

Bonsai
Bonsai ( ja, 盆栽, , tray planting, ) is the Japanese art of growing and training miniature trees in pots, developed from the traditional Chinese art form of ''penjing''. Unlike ''penjing'', which utilizes traditional techniques to produce entirely natural scenery in small pots that mimic the grandiose shapes of real life scenery, the Japanese "bonsai" only attempts to produce small trees that mimic the shape of real life trees. Similar versions of the art exist in other cultures, including the miniature living landscapes of Vietnamese . It was during the Tang dynasty, when ''penjing'' was at its height, that the art was first introduced in Japan. The loanword "bonsai" (a Japanese pronunciation of the Chinese term ''penzai'') has become an Hyponymy and hypernymy, umbrella term in English, attached to many forms of diminutive potted plants, and also on occasion to other living and non-living things. According to Stephen Orr in ''The New York Times'', "the term should be rese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Burtt Davy
Joseph Burtt Davy (7 March 1870 Findern, Derbyshire – 20 August 1940 Birmingham) was a Quaker botanist and agrostologist. He was the first curator of the Forest Herbarium (FHO) at the Imperial Forestry Institute when it was founded in 1924 under the Directorship of Professor Robert Scott Troup. He attended school at Ilkley in West Yorkshire. In 1891, he joined Kew Gardens as a technical assistant, leaving shortly after for the United States where he enrolled in the botany department at the University of California. Here he studied agriculture from 1893–96 and took up the post of botanist at the Agricultural Experiment Station in California between 1896–1901, describing the Cyperaceae and Gramineae for ''A Flora of Western Middle California'' by Willis Linn Jepson. Here he also met his wife-to-be, Alice Bolton (1863–1953), a native Californian. Davy wrote the pioneering work that was published in 1903, "Stock Ranges of Northwestern California: Notes on the Grasses and Fo ...

Henry Georges Fourcade
Henry Georges Fourcade, also known as Henri Georges Fourcade and sometimes Georges Henri Fourcade, was a surveyor, forester, pioneer of photogrammetry and as botanist, a major early collector of the Southern Cape flora. Early life Henry Georges was born at 16, Rue de Treuils, Bordeaux, the son of Justin Jadé Fourcade and Marie Prat. He had one other sibling, his older sister Jeanne Marie. His father was a general storekeeper, who soon moved to Yokohama, Japan and became an importer of wines and liqueurs, where the family lived at No. 10 on the Bund or waterfront. When he was twelve, he returned to France to finish his secondary school education, obtaining a school-leaving certificate just after turning fourteen, winning the first prize in ethics, as well as a prize in physics and chemistry. The next year he attended technikon and obtained good results in English, French, German, arithmetic, chemistry and commerce. In late-1880, Mrs. Fourcade, for reasons unknown, set sail ...

Keystone Species
A keystone species is a species which has a disproportionately large effect on its natural environment relative to its abundance, a concept introduced in 1969 by the zoologist Robert T. Paine. Keystone species play a critical role in maintaining the structure of an ecological community, affecting many other organisms in an ecosystem and helping to determine the types and numbers of various other species in the community. Without keystone species, the ecosystem would be dramatically different or cease to exist altogether. Some keystone species, such as the wolf, are also apex predators. The role that a keystone species plays in its ecosystem is analogous to the role of a keystone in an arch. While the keystone is under the least pressure of any of the stones in an arch, the arch still collapses without it. Similarly, an ecosystem may experience a dramatic shift if a keystone species is removed, even though that species was a small part of the ecosystem by measures of biomass o ...

Ostiole
An ''ostiole'' is a small hole or opening through which algae or fungi release their mature spores. The word is a diminutive of "ostium", "opening". The term is also used in higher plants, for example to denote the opening of the involuted syconium (fig inflorescence) through which fig wasps enter to pollinate and breed. Sometimes a stoma In botany, a stoma (from Greek ''στόμα'', "mouth", plural "stomata"), also called a stomate (plural "stomates"), is a pore found in the epidermis of leaves, stems, and other organs, that controls the rate of gas exchange.

Volatile Organic Compounds
Volatile organic compounds (VOCs) are organic compounds that have a high vapour pressure at room temperature Colloquially, "room temperature" is a range of air temperatures that most people prefer for indoor settings. It feels comfortable to a person when they are wearing typical indoor clothing. Human comfort can extend beyond this range depending on .... High vapor pressure correlates with a low boiling point, which relates to the number of the sample's molecules in the surrounding air, a trait known as volatility (chemistry), volatility. VOCs are responsible for the odor of scents and perfumes as well as pollutants. VOCs play an important role in communication between animals and plants, e.g. attractants for pollinators, protection from predation, and even inter-plant interactions. Some VOCs are dangerous to human health or cause harm to the natural environment, environment. Human impact on the environment, Anthropogenic VOCs are regulated by law, especially indoors, where c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fig Wasp
Fig wasps are wasps of the superfamily Chalcidoidea which spend their larval stage inside figs. Most are pollinators but others simply feed off the plant. The non-pollinators belong to several groups within the superfamily Chalcidoidea, while the pollinators are in the family Agaonidae. While pollinating fig wasps are gall-makers, the remaining types either make their own galls or usurp the galls of other fig wasps; reports of their being parasitoids are considered dubious. History Aristotle recorded in his ''History of Animals'' that the fruits of the wild fig (the caprifig) contain ''psenes'' (fig wasps); these begin life as grubs (larvae), and the adult ''psen'' splits its "skin" (pupa) and flies out of the fig to find and enter a cultivated fig, saving it from dropping. He believed that the ''psen'' was generated spontaneously; he did not recognise that the fig was reproducing sexually and that the ''psen'' was assisting in that process. Taxonomy The fig wasps are a pol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agaonidae
The family Agaonidae is a group of pollinating and nonpollinating fig wasps. They spend their larval stage inside the fruits of figs. The pollinating wasps (Agaoninae, Kradibiinae, and Tetrapusiinae) are the mutualistic partners of the fig trees. The nonpollinating fig wasps are parasitic. Extinct forms from the Eocene and Miocene are nearly identical to modern forms, suggesting that the niche has been stable over geologic time. Taxonomy The family has changed several times since its taxonomic appearance after the work of Francis Walker in 1846 described from the wasp genus '' Agaon''. Previously the subfamilies Epichrysomallinae, Otitesellinae, Sycoecinae, Sycoryctinae, Sycophaginae, and Agaoninae were the subdivisions of the family. Recent works building strong molecular phylogenies with an extended sampling size have changed the composition of Agaonidae. First, the paraphyletic groups have been excluded (Epichrysomallinae, Otitesellinae, Sycoecinae, and Sycoryctinae) and ne ...

Mozambique
Mozambique (), officially the Republic of Mozambique ( pt, Moçambique or , ; ny, Mozambiki; sw, Msumbiji; ts, Muzambhiki), is a country located in southeastern Africa bordered by the Indian Ocean to the east, Tanzania to the north, Malawi and Zambia to the northwest, Zimbabwe to the west, and Eswatini and South Africa to the southwest. The sovereign state is separated from the Comoros, Mayotte and Madagascar by the Mozambique Channel to the east. The capital and largest city is Maputo. Notably Northern Mozambique lies within the monsoon trade winds of the Indian Ocean and is frequentely affected by disruptive weather. Between the 7th and 11th centuries, a series of Swahili port towns developed on that area, which contributed to the development of a distinct Swahili culture and language. In the late medieval period, these towns were frequented by traders from Somalia, Ethiopia, Egypt, Arabia, Persia, and India. The voyage of Vasco da Gama in 1498 marked the arrival of t ...
