Cryptocarya Densiflora
''Cryptocarya'' is a genus of evergreen trees belonging to the laurel family, Lauraceae. The genus includes more than 350 species, distributed through the Neotropical, Afrotropical, Indomalayan, and Australasian realms. Overview The genus includes species of evergreen trees, distributed mostly in tropical and subtropical regions of South America, India, China, Java, New Guinea, Africa, Madagascar, and Mauritius, with seven species in Southern Africa. Common in the canopy, they grow up to 60 m, or as subcanopy trees in the succession climax species in tropical, lower temperate, or subtropical broadleaved forests. They are found in low-elevation evergreen forests and littoral rainforests, on all type of soils. The seeds are readily dispersed by fruit-eating birds, and seedlings and saplings have been recorded from other habitats where they are unlikely to develop to maturity. The genus name ''Cryptocarya'' is from a Greek word ''krypto'' meaning to hide, ''karya'' meaning a wal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Brown (Scottish Botanist From Montrose)
Robert Brown (21 December 1773 – 10 June 1858) was a Scottish botanist and paleobotanist who made important contributions to botany largely through his pioneering use of the microscope. His contributions include one of the earliest detailed descriptions of the cell nucleus and cytoplasmic streaming; the observation of Brownian motion; early work on plant pollination and fertilisation, including being the first to recognise the fundamental difference between gymnosperms and angiosperms; and some of the earliest studies in palynology. He also made numerous contributions to plant taxonomy, notably erecting a number of plant families that are still accepted today; and numerous Australian plant genera and species, the fruit of his exploration of that continent with Matthew Flinders. Early life Robert Brown was born in Montrose, Angus, Montrose on 21 December 1773, in a house that existed on the site where Montrose Library currently stands. He was the son of James Brown (Scottis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australasian Realm
The Australasian realm is a biogeographic realm that is coincident with, but not (by some definitions) the same as, the geographical region of Australasia. The realm includes Australia, the island of New Guinea (comprising Papua New Guinea and the Indonesian province of Papua), and the eastern part of the Indonesian archipelago, including the island of Sulawesi, the Moluccan islands (the Indonesian provinces of Maluku and North Maluku), and the islands of Lombok, Sumbawa, Sumba, Flores, and Timor, often known as the Lesser Sundas. The Australasian realm also includes several Pacific island groups, including the Bismarck Archipelago, Vanuatu, the Solomon Islands, and New Caledonia. New Zealand and its surrounding islands are a distinctive sub-region of the Australasian realm. The rest of Indonesia is part of the Indomalayan realm. In the classification scheme developed by Miklos Udvardy, New Guinea, New Caledonia, Solomon Islands and New Zealand are placed in the Oceania ...

Biological Dispersal
Biological dispersal refers to both the movement of individuals (animals, plants, fungi, bacteria, etc.) from their birth site to their breeding site ('natal dispersal'), as well as the movement from one breeding site to another ('breeding dispersal'). Dispersal is also used to describe the movement of propagules such as seeds and spores. Technically, dispersal is defined as any movement that has the potential to lead to gene flow. The act of dispersal involves three phases: departure, transfer, settlement and there are different fitness costs and benefits associated with each of these phases. Through simply moving from one habitat patch to another, the dispersal of an individual has consequences not only for individual fitness, but also for population dynamics, population genetics, and species distribution. Understanding dispersal and the consequences both for evolutionary strategies at a species level, and for processes at an ecosystem level, requires understanding on th ...

Tropical Climate
Tropical climate is the first of the five major climate groups in the Köppen climate classification identified with the letter A. Tropical climates are defined by a monthly average temperature of 18 °C (64.4 °F) or higher in the coolest month, and feature hot temperatures all year-round. Annual precipitation is often abundant in tropical climates, and shows a seasonal rhythm but may have seasonal dryness to varying degrees. There are normally only two seasons in tropical climates, a wet (rainy / monsoon) season and a dry season. The annual temperature range in tropical climates is normally very small. Sunlight is intense in these climates. There are three basic types of tropical climates within the tropical climate group: tropical rainforest climate (Af), tropical monsoon climate (Am) and tropical wet and dry climate or tropical savannah (Aw for dry winters, and As for dry summers), which are classified and distinguished by the precipitation and the precipitation lev ...

Cryptocarya Erythroxylon
''Cryptocarya erythroxylon'' is a medium to large rainforest tree, that grows from the Barrington Tops in New South Wales to the Gladstone area in Queensland. The common name is the pigeonberry ash, rose maple, or rose walnut. This is one of the largest laurels in Australia. Mature specimens usually reach around 35 metres tall, though there is a 57 metre tall tree at Murray Scrub near Kyogle close to the NSW–Queensland border. It grows between 500 and 1050 m altitude. Trees of the genus ''Cryptocarya'' are mostly from the tropics or warmer temperate areas. This tree is unusual as it grows in cooler regions, subject to frost and rare snowfall. It is also an unusually tall member of the genus. The trunk is often buttressed, and the grey or white cylindrical trunk is a conspicuous feature in the rainforest. Leaves are 6 to 13 centimetres long, white and veiny underneath. The small cream flowers form in early summer, the fruit is a black drupe maturing in the cooler months. Ger ...

Cryptocarya Alba
''Cryptocarya alba'', the peumo or Chilean acorn, is an evergreen tree that grows in Chile and Argentina from 33 to 40° southern latitude. It can live both in wet and as in dry conditions. Its distribution can reach up to 1500 meters (5000 ft) above sea level. It measures up to 20 meters (65 ft) height and one meter diameter, with cracked gray bark. An associate tree is the endangered Chilean Wine Palm, ''Jubaea chilensis'',C. Michael Hogan, 2008 which species prehistorically had a much wider range. Description Leaves are perennial, aromatic, simple, alternate and opposite, 2.5 to 8.5 cm long and one to four cm wide; aovate and entire lobe, a little undulate. The trunk is straight and hardly twisted; brown-grayish cork cambium, relatively smooth, with few cracks and detachable scales when old. Central branches thick and ascending; terminal twigs thin and hanging. The flowers are in dense bunches, greenish yellow and three to four mm long; hermaphrodite, they have ...

Deforestation
Deforestation or forest clearance is the removal of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. The most concentrated deforestation occurs in tropical rainforests. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, a half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute. The Food and Agriculture Organization of the United Nations defines deforestation as the conversion of forest to other land uses (regardless of whether it is human-induced). "Deforestation" and "forest area net change" are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a gi ...

Laurel Forest
Laurel forest, also called laurisilva or laurissilva, is a type of subtropical forest found in areas with high humidity and relatively stable, mild temperatures. The forest is characterized by broadleaf tree species with evergreen, glossy and elongated leaves, known as "laurophyll" or "lauroid". Plants from the laurel family (Lauraceae) may or may not be present, depending on the location. Ecology Laurel and laurophyll forests have a patchy distribution in warm temperate regions, often occupying topographic refugia where the moisture from the ocean condenses so that it falls as rain or fog and soils have high moisture levels.Abstract at NASA – MODIS: Izquierdo, T; de las Heras, P; Marquez, A (2011).

Aspidostemon
''Aspidostemon'' is a genus of flowering plants belonging to the family Lauraceae. It occurs in Madagascar. Taxonomy The genus was described by Jens Gunter Rohwer & Hans Georg Richter in ''Jahrbuch für Botanische Systematik, Pflanzengeschichte und Pflanzengeographie'' 109 (1): 74 in 1987. The type species is '' Aspidostemon perrieri'' ( Danguy) Rohwer. The number of collections available is not large. The identification was done at the Missouri Botanical Garden. Description They are shrubs or trees up to 25 m high, hermaphrodites. The leaves are entire, elliptical or narrowly elliptical. The fruit is a berry-like drupe dispersed mostly by birds. ''Aspidostemon'' species are no exception among the Lauraceae; they are trees with small flowers, hard to detect and collect and often overlooked or ignored when plants easier to collect or with showier flowers are at hand. ''Aspidostemon'' is characterized by its opposite leaves, flowers with three or six stamens (compared to 9 in '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endiandra
''Endiandra'' is a genus of about 126 species of plants, mainly trees, in the laurel family Lauraceae. They are commonly called "walnut" despite not being related to the Northern Hemisphere walnuts (''Juglans'' spp.) which are in the family Juglandaceae. Ecology Shrubs and trees with lauroid leaves mostly, with bisexual flowers, usually with a large edible berry ovoid or globose, and seated directly on the pedicel. The seeds are dispersed by animals and birds. They have a broad distribution across South East Asia, Australia and into the western Pacific Ocean. Endiandra is a genus of evergreen trees belonging to the Laurel family, Lauraceae. Fossils show that before glaciations, when the climate was more humid and mild, species were distributed more widely. They are distributed in Asia, from India to Indochina, China, Malaysia, Australia, and Pacific islands, with 38 species endemic to Australia. In Australia, they are often used as screen trees due to the thick foliage of a nu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
