Biak–Numfoor Rain Forests
The Biak–Numfoor rain forests is a tropical moist forest ecoregion in Indonesia. The ecoregion covers the islands of Biak, Supiori, Numfoor, and several smaller islands, which lie in Cenderawasih Bay north of Yapen and New Guinea. Geography Biak and Supiori are the largest islands in the ecoregion. They lie very close together, separated by a narrow and shallow channel. Numfoor lies southwest of Supiori and Biak. The Padaido Islands are a group of small islands south and southeast of Biak. The surface geology of Biak and Supiori consists mainly of rugged coralline limestone, with outcrops of schist overlain by basaltic lavas and tuffs. The highest elevations in the ecoregion are on Supiori, where a ridge of mountains parallel to Supiori's southern coast reaches in elevation. The islands are oceanic, and not part of the New Guinea continental shelf. Their physical isolation from New Guinea meant that plants and animals had to cross the ocean to get to the islands, givi ...

Australasian Realm
The Australasian realm is one of eight biogeographic realms 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 Moluccas (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 ...

Species Composition
Relative species abundance is a component of biodiversity and is a measure of how common or rare a species is relative to other species in a defined location or community.Hubbell, S. P. 2001. ''The unified neutral theory of biodiversity and biogeography''. Princeton University Press, Princeton, N.J. Relative abundance is the percent composition of an organism of a particular kind relative to the total number of organisms in the area. Relative species abundance (ecology), abundances tend to conform to specific patterns that are among the best-known and most-studied patterns in macroecology. Different populations in a community exist in relative proportions; this idea is known as relative abundance. Introduction Relative species abundance Relative species abundance and species richness describe key elements of biodiversity. Relative species abundance refers to how common or rare a species is relative to other species in a given location or community.McGill, B. J., Etienne R. S., Gra ...

Manjekia Maturbongsii
''Manjekia'' is a monotypic genus of palm for a species of palm native to Biak island, Indonesia, off the northwest coast of New Guinea. The genus was proposed in 2014. Its sole species is ''Manjekia maturbongsii'', which was first described in 2012 as ''Adonidia maturbongsii''. The specific epithet honours Rudi Maturbongs for his contributions to the study of palms in Biak. In 2014, the original authors decided that it was sufficiently distinct to be transferred from '' Adonidia'' to its own genus, ''Manjekia''. The transfer has been accepted by sources such as Plants of the World Online Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew.

Calophyllum
''Calophyllum'' is a genus of tropical flowering plants in the family Calophyllaceae. They are mainly distributed in Asia, with some species in Africa, the Americas, Australasia, and the Pacific Islands. History Members of the genus ''Calophyllum'' native to Malaysia and Wallacea are of particular importance to traditional shipbuilding of the larger Austronesian outrigger ships and were carried with them in the Austronesian expansion as they migrated to Oceania and Madagascar. They were comparable in importance to how oaks were in European shipbuilding and timber industries. The most notable species is the mastwood (''Calophyllum inophyllum'') which grows readily in the sandy and rocky beaches of the island environments that the Austronesians colonized. Description ''Calophyllum'' are trees or shrubs. They produce a colorless, white, or yellow latex. The oppositely arranged leaves have leathery blades often borne on petioles. The leaves are distinctive, with narrow parallel v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maniltoa
''Cynometra'' (from Greek calque of ''puki anjing'', local Malay name for '' C. cauliflora'' according to Rumphius) is genus of tropical forest trees with a pantropical distribution. Species of ''Cynometra'' are particularly important as forest components in West Africa and the Neotropics. '' Cynometra alexandri'' (muhimbi) is a familiar timber tree of central and east Africa. The genus is a member of the subfamily Detarioideae. It has been suggested that ''Cynometra'' is polyphyletic and is in need of revision. In 2019, beside description of 4 new species (i.e. '' Cynometra cerebriformis'', '' C. dwyeri'', '' C. steyermarkii'' and '' C. tumbesiana''), suggested that the species formerly recognized as '' Maniltoa'' should be included in this genus and some of the mainland tropical African species (those with asterisk in the list below) excluded from this genus because of their jointed pedicels and dehiscent fruits (he has not yet published any new combination for them, though) ...

Myristica
''Myristica'' is a genus of trees in the family Myristicaceae. There are over 150 species, distributed in Asia and the western Pacific as far as Vanuatu. The type species of the genus, and the most economically important member, is ''Myristica fragrans'' (the nutmeg tree), from which mace is also derived. Etymology The name ' is from the Greek adjective , meaning ‘fragrant, for anointing’, referring to its early use. The adjective is from the noun μύρον ''myron'' (‘perfume, ointment, anointing oil’). Description All or nearly all species are dioecious. Knuth (1904) however cites a report of trees being male in their sex expression when young and female later. Perianth of one whorl of three largely united segments. Stamens two to thirty, partly or wholly united.

Diospyros
''Diospyros'' is a genus of over 700 species of deciduous and evergreen trees and shrubs. The majority are native to the tropics, with only a few species extending into temperate regions. Individual species valued for their hard, heavy, dark timber, are commonly known as ebony trees, while others are valued for their fruit and known as persimmon trees. Some are useful as ornamentals and many are of local ecological importance. Species of this genus are generally dioecious, with separate male and female plants. Taxonomy and etymology The generic name ''Diospyros'' comes from a Latin name for the Caucasian persimmon ('' D. lotus''), derived from the Greek διόσπυρος : dióspyros, from ''diós'' () and ''pyrós'' (). The Greek name literally means "Zeus's wheat" but more generally intends "divine food" or "divine fruit". The genus is a large one and the number of species has been estimated variously, depending on the date of the source. The Royal Botanic Gardens, Kew, lis ...

Garcinia
''Garcinia'' is a genus of flowering plants in the family (biology), family Clusiaceae native to the Sundaland bioregion of Asia, America, Australia, tropical and southern Africa, and Polynesia. The number of species is disputed; Plants of the World Online (POWO) recognise up to 400. Commonly, the plants in this genus are called saptrees, mangosteens (which may also refer specifically to ''Garcinia mangostana''), or garcinias, and is one of several plants known as by the name "monkey fruit". The genus is named after French botanist Laurent Garcin (1683–1751). Trees of many species from this genus tend to grow deep in forested areas where other plants grow nearby. They are threatened by habitat destruction, and at least one species, ''Garcinia cadelliana, G. cadelliana'', from South Andaman Island, is almost or even completely extinct already. Description ''Garcinia'' species are evergreen trees and shrubs, dioecious and in several cases apomictic. Among neotropical ''Garcini ...

Terminalia (plant)
''Terminalia'' is a genus of large trees of the flowering plant family Combretaceae, comprising nearly 300 species distributed in Tropics, tropical regions of the world. The genus name derives from the Latin word ''terminus'', referring to the fact that the leaves appear at the very tips of the shoots. Terminalia latifolia, Axlewood (''T. latifolia'') is used for its wood and tannins and as a fodder. Terminalia leiocarpa, African birch (''T. leiocarpa'') is used for its wood and to make yellow dye and medicinal compounds. A yellow dyestuff produced from the leaves of ''T. leiocarpa'' has traditionally been used in West Africa to dye leather. Selected species There are 278 accepted ''Terminalia'' species as of July 2024 according to Plants of the World Online. Selected species include: *''Terminalia acuminata'' (Fr. Allem.) Eichl. *''Terminalia albida'' Scott-Elliot *''Terminalia amazonia'' (J.F.Gmel.) Exell – white olive *''Terminalia anogeissiana'' – axlew ...

Alstonia
''Alstonia'' is a widespread genus of evergreen trees and shrubs, of the family Apocynaceae. It was named by Robert Brown in 1811, after Charles Alston (1685–1760), professor of botany at Edinburgh from 1716 to 1760. The type species ''Alstonia scholaris'' (L.) R.Br. was originally named ''Echites scholaris'' by Linnaeus in 1767. Description ''Alstonia'' consists of about 40–60 species (according to different authors) native to tropical and subtropical Africa, Central America, Southeast Asia, Polynesia and Australia, with most species in the Malesian region. These trees can grow very large, such as ''Alstonia pneumatophora'', recorded with a height of 60 m and a diameter of more than 2 m. ''Alstonia longifolia'' is the only species growing in Central America (mainly shrubs, but also trees 20 m high). The leathery, sessile, simple leaves are elliptical, ovate, linear or lanceolate and wedge-shaped at the base. The leaf blade is dorsiventral, medium-sized to large and disp ...
