Protea Wentzeliana
''Protea wentzeliana'', also known as Wentzel's sugarbush, is a shrub belonging to the genus ''Protea''. The plant is found in the Chimanimani Mountains between Zimbabwe and Mozambique, as well as Malawi, southern Tanzania and central Angola. The shrub grows up to 1.6 m. It blooms mainly from May to December. The trunk is thin with few branches. The plant re-sprouts after a wildfire from an underground rootstock. The seeds are stored in a cap and released after they are ripe. The seeds are dispersed by means of the wind. The plant is monoecious with both sexes in each flower. Beetles are probably the creatures responsible for pollinating the flowers. The plant grows on poorly drained and wet soil in dongas and ditches in miombo The Miombo woodland is a tropical and subtropical grasslands, savannas, and shrublands biome (in the World Wide Fund for Nature scheme) located primarily in Central Africa. It includes four woodland savanna ecoregions (listed below) characterized .. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adolf Engler
Heinrich Gustav Adolf Engler (25 March 1844 – 10 October 1930) was a German botanist. He is notable for his work on plant taxonomy and phytogeography, such as ''Die natürlichen Pflanzenfamilien'' (''The Natural Plant Families''), edited with Karl A. E. von Prantl. Even now, his system of plant classification, the Engler system, is still used by many herbaria and is followed by writers of many manuals and floras. It is still the only system that treats all 'plants' (in the wider sense, algae to flowering plants) in such depth. Engler published a prodigious number of taxonomic works. He used various artists to illustrate his books, notably Joseph Pohl (1864–1939), an illustrator who had served an apprenticeship as a wood-engraver. Pohl's skill drew Engler's attention, starting a collaboration of some 40 years. Pohl produced more than 33 000 drawings in 6 000 plates for ''Die naturlichen Pflanzenfamilien''. He also illustrated ''Das Pflanzenreich'' (1900–1953), ''Die Pfl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monoecious
Monoecy (; adj. monoecious ) is a sexual system in seed plants where separate male and female cones or flowers are present on the same plant. It is a monomorphic sexual system alongside gynomonoecy, andromonoecy and trimonoecy. Monoecy is connected to anemophily. It can prevent self-pollination in an individual flower but cannot prevent self-pollination between male and female flowers on the same plant. Monoecy in angiosperms has been of interest for evolutionary biologists since Charles Darwin. Terminology Monoecious comes from the Greek words for one house. History The term monoecy was first introduced in 1735 by Carl Linnaeus. Darwin noted that the flowers of monoecious species sometimes showed traces of the opposite sex function. Monoecious hemp was first reported in 1929. Occurrence Monoecy is most common in temperate climates and is often associated with inefficient pollinators or wind-pollinated plants. It may be beneficial to reducing pollen-stigma i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Tanzania
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurm ...

Flora Of Mozambique
The wildlife of Mozambique consists of the flora and fauna of this country in southeastern Africa. Mozambique has a range of different habitat types and an ecologically rich and diverse wildlife. This includes 236 species of mammal, 740 species of bird and 5,692 species of vascular plant. The Maputaland-Pondoland-Albany hotspot, with significantly high levels of biodiversity, stretches from the southern tip of Mozambique into northeastern South Africa. Geography Mozambique is located on the southeast coast of Africa. It is bounded by Eswatini to the south, South Africa to the south and southwest, Zimbabwe to the west, Zambia and Malawi to the northwest, Tanzania to the north and the Indian Ocean to the east. Mozambique lies between latitudes 10° and 27°S, and longitudes 30° and 41°E. The country is divided into two topographical regions by the Zambezi River. To the north of the Zambezi, the narrow coastal strip gives way to inland hills and low plateaus. Rugged highla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Malawi
The wildlife of Malawi is composed of the flora and fauna of the country. Malawi is a landlocked country in southeastern Africa, with Lake Malawi taking up about a third of the country's area. It has around 187 species of mammal, some 648 species of birds have been recorded in the country and around 500 species of fish, many of them endemic, are found in its lakes and rivers. About 20% of the country has been set aside as national parks and game and forest reserves. Geography The flora and fauna are much influenced by the geography of the region. Malawi is a land-locked country, dominated by the Great Rift Valley which has a north – south orientation, and is long and between wide. The main feature is Lake Malawi which forms much of the eastern boundary of the country. The lake is drained by the Shire River which flows southwards to join the lower Zambezi in neighbouring Mozambique. Lake Malawi is above sea level but is deep in places. It is bordered on the west by a narrow p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Angola
The wildlife of Angola is composed of its flora and fauna. An atlas of the amphibians and reptiles of Angola was published in 2018, and reported 117 species of amphibians and 278 of reptiles. A major book on the biodiversity of Angola was published in 2019, and reported more than 2,000 species of organisms (plants, invertebrates and vertebrate animals), and 1,313 fossil species. Fauna Mammals Birds The avifauna of Angola includes a total of 983 species, of which 14 are endemic, 1 has been introduced by humans, and 4 are rare or accidental. 20 species are globally threatened. The western Angola Endemic Bird Area has 14 range-restricted species. Little is known about the conservation status of the region's birds due to the civil war that has raged in Angola for the last 27 years. The greatest diversity of restricted-range species is found in Cuanza Sul province, and given the uncertainty about their current status, many of these species are listed as Threatened. Gabela B ...

Miombo
The Miombo woodland is a tropical and subtropical grasslands, savannas, and shrublands biome (in the World Wide Fund for Nature scheme) located primarily in Central Africa. It includes four woodland savanna ecoregions (listed below) characterized by the dominant presence of ''Brachystegia'' and '' Julbernardia'' species of trees, and has a range of climates ranging from humid to semi-arid, and tropical to subtropical or even temperate. The trees characteristically shed their leaves for a short period in the dry season to reduce water loss and produce a flush of new leaves just before the onset of the wet season with rich gold and red colours masking the underlying chlorophyll, reminiscent of autumn colours in the temperate zone. The woodland gets its name from ''miombo'' (plural, singular ''muombo''), the Bemba word for ''Brachystegia'' species. Other Bantu languages of the region, such as Swahili and Shona, have related if not identical words, such as Swahili ''miyombo'' (singula ...

Dongas
The Dongas Tribe was a collection of Road protest in the United Kingdom, road protesters and travellers in England, noted for their occupation of Twyford Down outside Winchester, England, Winchester, Hampshire. The name ''Dongas'' comes from the Northern Ndebele language, Matabele word for "gully", given by Winchester locals to the deep drovers' tracks on Twyford Down. John Vidal, writing in ''The Guardian'' in 2012, said of The Dongas that "the 15-20 urban youths who camped out to try to defend Twyford Down in 1992 are recognised to have fired up British environmental protest and kickstarted a major shift in green attitudes in both government and the public." History The Twyford Down protest was a protest against the M3 motorway (Great Britain), M3 motorway extension which destroyed some rich ecological sites, one of the very few habitats of the Chalkhill Blue, Chalkhill Blue butterfly and six species of rare orchid, and ancient monuments there (Site of Special Scientific Intere ...

Pollination
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 ...

Beetle
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly har ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wildfire
A wildfire, forest fire, bushfire, wildland fire or rural fire is an unplanned, uncontrolled and unpredictable fire in an area of combustible vegetation. Depending on the type of vegetation present, a wildfire may be more specifically identified as a bushfire( in Australia), desert fire, grass fire, hill fire, peat fire, prairie fire, vegetation fire, or veld fire. Some natural forest ecosystems depend on wildfire. Wildfires are distinct from beneficial human usage of wildland fire, called controlled burning, although controlled burns can turn into wildfires. Fossil charcoal indicates that wildfires began soon after the appearance of terrestrial plants approximately 419 million years ago during the Silurian period. Earth's carbon-rich vegetation, seasonally dry climates, atmospheric oxygen, and widespread lightning and volcanic ignitions create favorable conditions for fires. The occurrence of wildfires throughout the history of terrestrial life invites conjecture tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shrub
A shrub (often also called a bush) is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some definitions state that a shrub is less than and a tree is over 6 m. Others use as the cut-off point for classification. Many species of tree may not reach this mature height because of hostile less than ideal growing conditions, and resemble a shrub-sized plant. However, such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in a class between perennials and trees; some may only last about fiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
