Commensalism is a long-term biological interaction (symbiosis) in which members of one species gain benefits while those of the other species neither benefit nor are harmed. This is in contrast with mutualism, in which both organisms benefit from each other; amensalism, where one is harmed while the other is unaffected; parasitism, where one is harmed and the other benefits, and parasitoidism, which is similar to parasitism but the parasitoid has a free-living state and instead of just harming its host it eventually ends up killing it. The commensal may obtain nutrients, shelter, support, or locomotion from the host species, which is substantially unaffected. The commensal relation is often between a larger host and a smaller commensal; the host organism is unmodified, whereas the commensal species may show great structural adaptation consistent with its habits, as in the remoras that ride attached to sharks and other fishes. Remoras feed on their hosts' fecal matter, while pilot fish feed on the leftovers of their hosts' meals. Numerous birds perch on bodies of large mammal herbivores or feed on the insects turned up by grazing mammals.
Guibourtia is a flowering plant genus in the family Fabaceae, also known by the common names as Rhodesian teak, African rosewood, amazique, bubinga, kevazingo and ovangkol.
The subfamily Detarioideae is one of the subdivisions of the plant family Fabaceae (legumes). This subfamily includes many tropical trees, some of which are used for timber or have ecological importance. The subfamily consists of 84 genera, most of which are native to Africa and Asia. Pride of Burma and tamarind are two of the most notable species in Detarioideae. It has the following clade-based definition:
The most inclusive crown clade containing Goniorrhachis marginataTaub. and Aphanocalyx cynometroidesOliv., but not Cercis canadensisL., Duparquetia orchidaceaBaill., or Bobgunnia fistuloides(Harms) J. H. Kirkbr. & Wiersema.
Aechmea is a genus of flowering plants in the family Bromeliaceae. The name comes from the Greek aichme, meaning "spear". Aechmea comprises eight subgenera and around 250 species distributed from Mexico through South America and the Caribbean. Most of the species in this genus are epiphytes.
Anthonotha is a genus within the subfamily Detarioideae of the plant family Fabaceae.
Crudia is a genus of plants in the family Fabaceae.
Daniellia is a genus of plants in the family Fabaceae, named after William Freeman Daniell.
Didelotia idae is a species of plant in the family Fabaceae. It is found in Ivory Coast, Ghana, Liberia and Sierra Leone. It is threatened by habitat loss.
Didelotia unifoliolata is a species of plant in the family Fabaceae. It is found in Cameroon, Democratic Republic of the Congo, Gabon, Ghana, possibly Ivory Coast, possibly Liberia, and possibly Sierra Leone. It is threatened by habitat loss.
Englerodendron is a small genus of legumes that are native to tropical Africa.
Gilbertiodendron is a genus of legume in the family Fabaceae. It consists of about 25 species of tree native to tropical Africa. Members of this genus were formerly considered to be in the genus Macrolobium but that genus is now restricted to species growing in tropical America. It is closely related to Pellegriniodendron.
Gilletiodendron is a genus of plants in the family Fabaceae.
Julbernardia is a genus of plants in the family Fabaceae. There are eight species found in tropical Africa. They are medium-sized trees.
Loesenera is a genus of plants in the family Fabaceae.
Plagiosiphon is a genus of plants in the family Fabaceae.
Tessmannia is a genus of flowering plants in the family Fabaceae.
Tetraberlinia is a genus of plants in the family Fabaceae.
Zenkerella is a genus of plants in the family Fabaceae.
Aeschynomene is a genus of flowering plants in the family Fabaceae, and was recently assigned to the informal monophyletic Dalbergia clade of the Dalbergieae. They are known commonly as jointvetches. These legumes are most common in warm regions and many species are aquatic. The genus as currently circumscribed is paraphyletic and it has been suggested that the subgenus Ochopodium be elevated to a new genus within the Dalbergieae, though other changes will also be required to render the genus monophyletic.
Prioria is a genus of flowering plants in the family Fabaceae. Members of this genus are found in Central America, Africa, southern Asia, and Oceania.
