Monodominant
Monodominance is an ecological condition in which more than 60% of the tree canopy comprises a single species of tree.Peh, Kelvin S.-H.; Lewis, Simon L.; Lloyd, Jon (July 2011). "Mechanisms of monodominance in diverse tropical tree-dominated systems". Journal of Ecology (British Ecological Society) 99 (4): 891–898.doi:10.1111/j.1365-2745.2011.01827.x.-Prebble, Matthew; Kennedy, Jean; Southern, Wendy (2010). "Holocene lowland vegetation change and human ecology in Manus Province, Papua New Guinea". In Haberle, S.; Stevenson, J.; Prebble, M. Altered Ecologies: Fire, Climate and Human Influence on Terrestrial Landscapes. Terra Australis Series 32. ANU E Press. . Monodominant forests are quite common under conditions of extra-tropical climate types. Although monodominance is studied across different regions, most research focuses on the many prominent species in tropical forests.

Ecology
Ecology () is the study of the relationships between living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. Ecology is a branch of biology, and it is not synonymous with environmentalism. Among other things, ecology is the study of: * The abundance, biomass, and distribution of organisms in the context of the environment * Life processes, antifragility, interactions, and adaptations * The movement of materials and energy through living communities * The successional development of ecosystems * Cooperation, competition, and predation within and between species * Patterns of biodiversity and its effect on ecosystem processes Ecology has practical applications in conservation biology, wetland management, natural resource managemen ...

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

Tropics
The tropics are the regions of Earth surrounding the Equator. They are defined in latitude by the Tropic of Cancer in the Northern Hemisphere at N and the Tropic of Capricorn in the Southern Hemisphere at S. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). In terms of climate, the tropics receive sunlight that is more direct than the rest of Earth and are generally hotter and wetter as they aren't affected as much by the solar seasons. The word "tropical" sometimes refers to this sort of climate in the zone rather than to the geographical zone itself. The tropical zone includes deserts and snow-capped mountains, which are not tropical in the climatic sense. The tropics are distinguished from the other climatic and biomatic regions of Earth, which are the middle latitudes and the polar regions on either side of the equatorial zone. The tropics constitute 40% of Earth's surface area and contain 36% of Earth's landmass. , the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cynometra Alexandri
''Cynometra alexandri'', the Uganda ironwood or muhimbi, is a species of legume that occurs in tropical lowland forests of central and east Africa. They grow gregariously in drier forest types and as a constituent of swamp forests. They reach some to in height, and larger trees often develop hollow boles and buttress roots. Taxonomy According to (2019), ''Cynometra alexandri'' along with other mainland tropical African (but not all) species of the genus ''Cynometra'' should be excluded from the genus and will be transferred to a new as yet un-named genus in the future. Distribution and habitat In Uganda it is widespread in the lowland forests (below 2,000 metres a.s.l) in the Western Rift Escarpment, where it shows a tendency toward monospecific dominance. After initial colonising, a mixed forest would contain Uganda ironwood, '' Alstonia congensis'', '' Trichilia prieuriana'', ''Khaya anthotheca'' and ''Celtis mildbraedii''. When climax forest develops at altitudes between ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gilbertiodendron Dewevrei
''Gilbertiodendron dewevrei'' is a species of tree in the family Fabaceae, native to tropical rain forests in Central Africa. It is often the dominant tree species of the Guineo-Congolian rainforest. The timber is traded as ''limbali'', and is used for construction, flooring and railway sleepers. It is also used for making boats, furniture, tool handles and joinery and for making charcoal. Description ''Gilbertiodendron dewevrei'' is a large evergreen tree, reaching a height of up to . The crown is dense and allows little light through. The unbuttressed trunk is cylindrical, with a diameter of up to or more, the lower half usually being devoid of branches.

Canopy (biology)
In biology, the canopy is the aboveground portion of a plant cropping or crop, formed by the collection of individual plant crowns. In forest ecology, canopy also refers to the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms ( epiphytes, lianas, arboreal animals, etc.). The communities that inhabit the canopy layer are thought to be involved in maintaining forest diversity, resilience, and functioning. Sometimes the term canopy is used to refer to the extent of the outer layer of leaves of an individual tree or group of trees. Shade trees normally have a dense canopy that blocks light from lower growing plants. Observation Early observations of canopies were made from the ground using binoculars or by examining fallen material. Researchers would sometimes erroneously rely on extrapolation by using more reachable samples taken from the understory. In some cases, they would use unconventional methods such as chairs susp ...

Ectomycorrhiza
An ectomycorrhiza (from Greek ἐκτός ', "outside", μύκης ', "fungus", and ῥίζα ', "root"; pl. ectomycorrhizas or ectomycorrhizae, abbreviated EcM) is a form of symbiotic relationship that occurs between a fungal symbiont, or mycobiont, and the roots of various plant species. The mycobiont is often from the phyla Basidiomycota and Ascomycota, and more rarely from the Zygomycota. Ectomycorrhizas form on the roots of around 2% of plant species, usually woody plants, including species from the birch, dipterocarp, myrtle, beech, willow, pine and rose families. Research on ectomycorrhizas is increasingly important in areas such as ecosystem management and restoration, forestry and agriculture. Unlike other mycorrhizal relationships, such as arbuscular mycorrhiza and ericoid mycorrhiza, ectomycorrhizal fungi do not penetrate their host's cell walls. Instead they form an entirely intercellular interface known as the Hartig net, consisting of highly branched hyphae form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asia
Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area of , about 30% of Earth's total land area and 8.7% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, ...
