Combretum
''Combretum'', the bushwillows or combretums, make up the type genus of the family Combretaceae. The genus comprises about 272 species of trees and shrubs, most of which are native to tropical and southern Africa, about 5 to Madagascar, but there are others that are native to tropical Asia, New Guinea and the Bismarck Archipelago, Australia, and tropical America. Though somewhat reminiscent of willows (''Salix'') in their habitus, they are not particularly close relatives of these. Ecology Bushwillow trees often are important plants in their habitat. Savannahs in Africa, in particular those growing on granitic soils, are often dominated by ''Combretum'' and its close relative '' Terminalia''. For example, ''C. apiculatum'' is a notable tree in the Angolan mopane woodlands ecoregion in the Kunene River basin in southern Africa. Other species of this genus are a major component of Southwestern Amazonian moist forests. This genus contains several species that are pollinated ...

Combretaceae
The Combretaceae, often called the white mangrove family, are a family of flowering plants in the order Myrtales. The family includes about 530 species of trees, shrubs, and lianas in ca 10 genera. The family includes the leadwood tree, ''Combretum imberbe''. Three genera, '' Conocarpus'', '' Laguncularia'', and '' Lumnitzera'', grow in mangrove habitats (mangals). The Combretaceae are widespread in the subtropics and tropics. Some members of this family produce useful construction timber, such as idigbo from '' Terminalia ivorensis''. The commonly cultivated ''Quisqualis indica'' is now placed in the genus ''Combretum''. Many plants in the Quisqualis species contain the Non-proteinogenic amino acid excitotoxin Quisqualic acid, a potent AMPA agonist.Excitotoxic cell death and delayed rescue in human neurons derived from NT2 cells, M Munir, L Lu and P Mcgonigl, Journal of Neuroscience, Vol 15, 7847–7860 White mangroves The family name comes from the type genus ''Combretum''; it ...

Savannah
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. According to '' Britannica'', there exists four savanna forms; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in f ...

Alchornea
''Alchornea'' is a plant genus of the family (biology), family Euphorbiaceae first described as a genus in 1788. It is widespread in tropical and subtropical regions of Africa, South Asia, Australia, Latin America, and various oceanic islands. Molecular phylogenetic analyses suggest that ''Bocquillonia'' from New Caledonia is nested in ''Alchornea''.Wurdack, K. J., P. Hoffmann, and M. W. Chase (2005).

Southwestern Amazonian Moist Forests
The Southwest Amazon moist forests (NT0166) is an ecoregion located in the Upper Amazon basin. The forest is characterized by a relatively flat landscape with alluvial plains dissected by undulating hills or high terraces. The biota of the southwest Amazon moist forest is very rich because of these dramatic edaphic and topographical variations at both the local and regional levels. This ecoregion has the highest number of both mammals and birds recorded for the Amazonian biogeographic realm: 257 with 11 endemic species for mammals and 782 and 17 endemics for birds. The inaccessibility of this region, along with few roads, has kept most of the habitat intact. Also, there are a number of protected areas, which preserve this extremely biologically rich ecoregion. Location The southwest Amazon moist forest region covers an extensive area of the Upper Amazon Basin comprising four sub-basins: (1) both the Pastaza- Marañon and (2) Ucayali River sub-basins drain into the Upper A ...

Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammal
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla ( hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla (cetaceans and even-toed ungulates), and the Carnivora ( cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, toget ...

Pollinated
Pollination is the transfer of pollen from an anther of a plant to the stigma of a plant, later enabling fertilisation and the production of seeds, most often by an animal or by wind. Pollinating agents can be animals such as insects, birds, and bats; water; wind; and even plants themselves, when self-pollination occurs within a closed flower. Pollination often occurs within a species. When pollination occurs between species, it can produce hybrid offspring in nature and in plant breeding work. In angiosperms, after the pollen grain (gametophyte) has landed on the stigma, it germinates and develops a pollen tube which grows down the style until it reaches an ovary. Its two gametes travel down the tube to where the gametophyte(s) containing the female gametes are held within the carpel. After entering an ovum cell through the micropyle, one male nucleus fuses with the polar bodies to produce the endosperm tissues, while the other fuses with the ovule to produce the embryo. He ...

Kunene River
The Cunene (Portuguese spelling) or Kunene (common Namibian spelling) is a river in Southern Africa. It flows from the Angola highlands south to the border with Namibia. It then flows west along the border until it reaches the Atlantic Ocean. It is one of the few perennial rivers in the region. It is about long, with a drainage basin in area. Its mean annual discharge is 174 m3/s (6,145 cfs) at its mouth. The Epupa Falls lie on the river. Olushandja Dam dams a tributary of the river, the Etaka, and helps provide the Ruacana Power Station with water. Dam controversies The Namibian government proposed in the late 1990s to build the Epupa Dam, a controversial hydroelectric dam on the Cunene. In 2012 the Governments of Namibia and Angola announced plans to jointly build the Orokawe dam in the Baynes Mountains. According to the indigenous Himba who would have been most affected by the construction of the dam, the dam threatens the local ecosystem and therefore the economic ...

Angolan Mopane Woodlands
Angolan mopane woodlands are situated in southwestern Angola, extending into northern Namibia. This ecosystem surrounds Etosha Pan, which is considered a separate ecoregion. The mopane trees are the main type of vegetation. Location and description In Angola the region mostly comprises the southern Cunene Province and in Namibia in the regions of Omusati, Oshana and the eastern inland arm of Kunene and areas of Oshikoto surrounding the Etosha Pan. The ecoregion includes the Cunene River which divides the two countries, and is one of the main sources of water in this dry region. The landscape is mainly flat. The rainy season is late summer. The mopane woodlands are bounded on the west by the drier Namibian savanna woodlands. The Angolan miombo woodlands lie to the north, the Zambezian Baikiaea woodlands to the northeast, and the Kalahari Acacia-Baikiaea woodlands to the east. The drier Kalahari xeric savanna lies to the south.Burgess, Neil, Jennifer D'Amico Hales, Emma Under ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terminalia (plant)
''Terminalia'' is a genus of large trees of the flowering plant family Combretaceae, comprising nearly 300 species distributed in tropical regions of the world.
