Urochloa Mosambicensis
''Urochloa trichopus'', bushveld signal grass is a species of grass that is native to tropical and southern parts of Africa, Arabian Peninsula and western Madagascar. Description It is clump-forming grass that can grow up to meters tall, with alternate spaced leaves. The leaf sheath is glabrous (hairless) to slightly pubescent (having small hairs). The leaf blade is linear, acuminate (tapering to a long point) and long and wide. The flower consists of 3–20 racemes carried on a central axis long. They are solitary, ovate shaped spikelets on a narrowly winged rachis (shaft). They are 2-flowered with lower floret male and upper Monoecy, bisexual. They have 3 stamens. The ovary has 2 plumose (having feathers or featherlike growths) Stigma (botany), stigmas. The seed capsule is a strongly flattened caryopsis (grain). It flowers and fruits between June and August. Distribution It is native to the African countries of Angola, Botswana, Burkina, Cameroon, Chad, Congo, Eritrea, Et ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panicle
In botany, a panicle is a much-branched inflorescence. (softcover ). Some authors distinguish it from a compound spike inflorescence, by requiring that the flowers (and fruit) be pedicellate (having a single stem per flower). The branches of a panicle are often racemes. A panicle may have determinate or indeterminate growth. This type of inflorescence is largely characteristic of grasses, such as oat and crabgrass, as well as other plants such as pistachio and mamoncillo. Botanists use the term paniculate in two ways: "having a true panicle inflorescence" as well as "having an inflorescence with the form but not necessarily the structure of a panicle". Corymb A corymb may have a paniculate branching structure, with the lower flowers having longer pedicels than the upper, thus giving a flattish top superficially resembling an umbel. Many species in the subfamily Amygdaloideae, such as hawthorns and rowans, produce their flowers in corymbs. up'' Sorbus glabrescens'' co ...

Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Livestock
Livestock are the Domestication, domesticated animals that are raised in an Agriculture, agricultural setting to provide labour and produce diversified products for consumption such as meat, Egg as food, eggs, milk, fur, leather, and wool. The term is sometimes used to refer solely to animals which are raised for consumption, and sometimes used to refer solely to farmed ruminants, such as cattle, sheep, and goats. The breeding, maintenance, slaughter and general subjugation of livestock called ''animal husbandry'', is a part of modern agriculture and has been practiced in many cultures since humanity's transition to farming from hunter-gatherer lifestyles. Animal husbandry practices have varied widely across cultures and periods. It continues to play a major economic and cultural role in numerous communities. Livestock farming practices have largely shifted to intensive animal farming. Intensive animal farming increases the yield of the various commercial outputs, but also nega ...

Neotropical Realm
The Neotropical realm is one of the eight biogeographic realms constituting Earth's land surface. Physically, it includes the tropics, tropical Ecoregion#Terrestrial, terrestrial ecoregions of the Americas and the entire South American temperate climate, temperate zone. Definition In biogeography, the Neotropic or Neotropical realm is one of the eight terrestrial realms. This realm includes South America, Central America, the Caribbean Islands, and southern North America. In Mexico, the Yucatán Peninsula and southern lowlands, and most of the east and west coastlines, including the southern tip of the Baja California Peninsula are Neotropical. In the United States southern Florida and coastal Central Florida are considered Neotropical. The realm also includes temperate southern South America. In contrast, the Neotropical Phytochorion, Floristic Kingdom excludes southernmost South America, which instead is placed in the Antarctic Floristic Kingdom, Antarctic kingdom. The Neo ...

Weed
A weed is a plant considered undesirable in a particular situation, growing where it conflicts with human preferences, needs, or goals.Harlan, J. R., & deWet, J. M. (1965). Some thoughts about weeds. ''Economic botany'', ''19''(1), 16-24. Plants with characteristics that make them hazardous, aesthetically unappealing, difficult to control in managed environments, or otherwise unwanted in agriculture, farm land, Orchard, orchards, gardens, lawns, Park, parks, recreational spaces, residential and industrial areas, may all be considered weeds.Holzner, W., & Numata, M. (Eds.). (2013). ''Biology and ecology of weeds'' (Vol. 2). Springer Science & Business Media. The concept of weeds is particularly significant in agriculture, where the presence of weeds in fields used to grow crops may cause major losses in yields. Invasive species, plants introduced to an environment where their presence negatively impacts the overall functioning and biodiversity of the ecosystem, may also sometime ...

Eurasian Collared Dove
The Eurasian collared dove (''Streptopelia decaocto''), often simply just collared dove, is a dove species native to Europe, Asia, and northern Africa. It has also been introduced to Japan, North and Central America, and the islands in the Caribbean. Taxonomy The Hungarian naturalist Imre Frivaldszky first described the Eurasian collared dove with the scientific name ''Columba risoria'' varietas ''C. decaocto'' in 1838, considering it a wild variety of the domesticated barbary dove. The type locality is Plovdiv in Bulgaria. It is now placed in genus ''Streptopelia'' that was described in 1855 by the French ornithologist Charles Lucien Bonaparte. The Burmese collared dove (''S. xanthocycla'') was formerly considered a subspecies of the Eurasian collared dove, but was split as a distinct species by the IOC in 2021. Two other subspecies were formerly sometimes accepted, ''S. d. stoliczkae'' from Turkestan in central Asia and ''S. d. intercedens'' from southern India and Sri L ...

Aristida
''Aristida'' is a very nearly Cosmopolitan distribution, cosmopolitan genus of plants in the Poaceae, grass family. ''Aristida'' is distinguished by having three Awn (Botany), awns (bristles) on each lemma (botany), lemma of each floret. The genus includes about 300 species found worldwide, often in arid warm regions. This genus is among those colloquially called three-awns wiregrass (other), wiregrasses, speargrass (other), speargrasses and needlegrass (other), needlegrasses. The name ''Aristida'' is derived from the Latin "wikt:arista#Latin, arista", meaning "awn". They are characteristic of semiarid grassland. The Wiregrass Region of North America is named for ''Aristida stricta, A. stricta''. Other locales where this genus is an important component of the ecosystem include the Carolina Bays, the sandhills (Carolina), sandhills of the Carolinas, and sandhill, elsewhere, Acacia aneura, Mulga scrub in Australia, and the xeric grasslands around Lake Tur ...

Ecotone
An ecotone is a transitional area between two plant communities, where these meet and integrate. Examples include areas between grassland and forest, estuaries and lagoon, freshwater and sea water etc. An ecotone may be narrow or wide, and it may be local (the zone between a field and forest) or regional (the transition between forest and grassland ecosystems). An ecotone may appear on the ground as a gradual blending of the two communities across a broad area, or it may manifest itself as a sharp boundary line. Etymology The word ''ecotone'' was coined (and its etymology given) in 1904 in "The Development and Structure of Vegetation" (Lincoln, Nebraska: Botanical Seminar) by Frederic E. Clements. It is formed as a combination of ''ecology'' plus ''-tone'', from the Greek ''tonos'' or tension – in other words, a place where ecologies are in tension. Features There are several distinguishing features of an ecotone. First, an ecotone can have a sharp vegetation transition, wi ...

Termite
Termites are a group of detritivore, detritophagous Eusociality, eusocial cockroaches which consume a variety of Detritus, decaying plant material, generally in the form of wood, Plant litter, leaf litter, and Humus, soil humus. They are distinguished by their moniliform antennae and the soft-bodied, unpigmented worker caste for which they have been commonly termed "white ants"; however, they are not ants but highly Apomorphy and synapomorphy, derived cockroaches. About 2,997 extant species are currently described, 2,125 of which are members of the family Termitidae. Termites comprise the infraorder Isoptera, or alternatively the Taxonomic rank#All ranks, epifamily Termitoidae, within the order Blattodea (the cockroaches). Termites were once classified in a separate Order (biology), order from cockroaches, but recent phylogenetic studies indicate that they evolved from cockroaches, as they are deeply nested within the group, and the sister group to wood-eating cockroaches of t ...

Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) biome and 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. Four savanna forms exist; ''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 forests.Manoel Cláudio da ...
