Trinervitermes
''Trinervitermes'' is a termite genus belonging to family Termitidae. Members are native to the Old World. They inhabit grasslands and store grass in their nests or mounds, just below the ground surface. Their grass-collecting activities are mainly nocturnal. The soldier caste has atrophied mandibles and a fontanelle squirt gun on the frons. Diterpenes and monoterpenes are released to deter ants and smaller predators, but these are not effective against larger mammalian predators. Due to the snout A snout is the protruding portion of an animal's face, consisting of its nose, mouth, and jaw. In many animals, the structure is called a muzzle, Rostrum (anatomy), rostrum, beak or proboscis.

Trinervitermes Trinervoides
''Trinervitermes trinervoides'' is a species of termite belonging to family Termitidae. It is native to and widespread in southern Africa where it inhabits mesic to semi-arid grasslands. Due to the snout on the head of soldiers, and their grass collecting habits, they are known as snouted harvester termites. Range and habitat It is found in South Africa, Namibia, Zimbabwe and Mozambique, and is widely distributed and common south of the Limpopo River. The species lives in savannah or grassland areas, and avoids barren land. Related species are found in the east of the subcontinent. Biology The snouted harvester termite is a mostly nocturnal species. The species stores grass within its mounds, just beneath the surface. Evidence shows that the species is probably not polycalic and thus each mound will house only a single colony. Since the soldier termites of this species can shoot aversive chemical compounds through their fontanelle squirt gun located on their heads, African insec ...

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 ...

Nils Holmgren
Nils Frithiof Holmgren (September 28, 1877 – September 7, 1954) was a Swedish zoologist and comparative anatomist. He was professor of zoology at Stockholm University from 1921 to 1944. He took a special interest in the taxonomy of termites. Holmgren went to the Stockholm University College and in 1906 he defended his doctoral dissertation at the newly created Stockholm University. In 1912 he became a teacher at the zoological institute, and in 1919 assistant professor of zoology (replacing Wilhelm Leche), and in 1921 full professor. His early work focussed on the biology, systematics and anatomy of insects, especially termites, as in (1906) and (1909–1912). In later work he focused on the structure of the brain in worms, arthropods and vertebrates, publishing (1916) (Comparative anatomy of the brain), (1919), (1920), ''Points of view concerning forebrain morphology in lower vertebrates'' (1922), (with C. J. van der Horst) ''Contribution to the morphology of the brain' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Termitidae
Termitidae is the largest family of termites consisting of 2,125 described species of which are commonly known as the higher termites. They are evolutionarily the most specialised termite group, with their highly compartmentalized hindgut lacking the flagellated protozoans common to "lower termites", which are instead replaced by bacteria and archaea. Whereas lower termites are restricted mostly to woody tissue, higher termites have diverse diets consisting of wood, grass, leaf litter, fungi, lichen, faeces, humus and soil. Around 60% of species rely on soil-feeding alone. Systematics The family contains the following subfamilies: : Family Termitidae Latreille, 1802 :: subfamily Sphaerotermitinae Engel & Krishna, 2004 :: subfamily Macrotermitinae Kemner, 1934, nomen protectum CZN 2003/small> (synonyms: Acanthotermitinae Sjöstedt, 1926, nomen rejiciendum CZN 2003 Odontotermitini Weidner, 1956) :: subfamily Foraminitermitinae Holmgren, 1912 (synonym: Pseudomicrotermiti ...

Old World
The "Old World" () is a term for Afro-Eurasia coined by Europeans after 1493, when they became aware of the existence of the Americas. It is used to contrast the continents of Africa, Europe, and Asia in the Eastern Hemisphere, previously thought of by the Europeans as comprising the entire world, with the "New World", a term for the newly encountered lands of the Western Hemisphere, particularly the Americas. Etymology In the context of archaeology and world history, the term "Old World" includes those parts of the world which were in (indirect) cultural contact from the Bronze Age onwards, resulting in the parallel development of the early civilizations, mostly in the temperate zone between roughly the 45th and 25th parallels north, in the area of the Mediterranean, including North Africa. It also included Mesopotamia, the Persian plateau, the Indian subcontinent, China, and parts of Sub-Saharan Africa. These regions were connected via the Silk Road trade route, and ...

Diterpene
Diterpenes are a class of terpenes composed of four isoprene units, often with the molecular formula C20H32. They are biosynthesized by plants, animals and fungi via the HMG-CoA reductase pathway, with geranylgeranyl pyrophosphate being a primary intermediate. Diterpenes form the basis for biologically important Chemical compound, compounds such as retinol, retinal, and phytol. Some diterpenes are known to be antimicrobial and anti-inflammatory. Structures As with most terpenes a huge number of potential structures exists, which may be broadly divided according to the number of rings present. Biosynthesis Diterpenes are derived from the addition of one Isopentenyl pyrophosphate, IPP unit to Farnesyl pyrophosphate, FPP to form geranylgeranyl pyrophosphate (GGPP). From GGPP, structural diversity is achieved mainly by two classes of enzymes; the diterpene synthases and Cytochrome P450, cytochromes P450. Several diterpenes are produced by plants and cyanobacteria. GGPP is also t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
