Crematogaster Carinata
''Crematogaster carinata'' is a species of ant in the tribe Crematogastrini. It was first described by Gustav Mayr in 1862. It is native to Central and South America, where it is a common species, forming large colonies in the canopy of the forest. Description Workers of ''C. carinata'' are small, and there is only one class. The head, thorax and abdomen are reddish brown, while the mandibles, the tips of the antennae and the tarsi are yellowish. Distribution and habitat ''Crematogaster carinata'' is native to the Neotropics, its range extending from Costa Rica southward to Bolivia and southern Brazil. It is a widespread species and is found in humid rainforest, and other types of wet lowland forest, at altitudes of up to . In a survey of ants in a of lowland primary rainforest in Ecuador, 489 species of ant were found. ''C. carinata'' were the most common species found in the canopy, the electric ant (''Wasmannia auropunctata'') was the most abundant on the ground whil ...

Scale Insect
Scale insects are small insects of the order Hemiptera, suborder Sternorrhyncha. Of dramatically variable appearance and extreme sexual dimorphism, they comprise the infraorder Coccomorpha which is considered a more convenient grouping than the superfamily Coccoidea due to taxonomic uncertainties. Adult females typically have soft bodies and no limbs, and are concealed underneath domed scales, extruding quantities of wax for protection. Some species are hermaphroditic, with a combined ovotestis instead of separate ovaries and testes. Males, in the species where they occur, have legs and sometimes wings, and resemble small flies. Scale insects are herbivores, piercing plant tissues with their mouthparts and remaining in one place, feeding on sap. The excess fluid they imbibe is secreted as honeydew on which sooty mold tends to grow. The insects often have a mutualistic relationship with ants, which feed on the honeydew and protect them from predators. There are about 8,000 descr ...

Hymenoptera Of South America
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they mature. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek πτερόν (''pteron'') for wing. The Ancient Greek ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings. However, a key characteristic of this order is that the hindwings are co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crematogaster
''Crematogaster'' is an ecologically diverse genus of ants found worldwide, which are characterised by a distinctive heart-shaped gaster (abdomen), which gives them one of their common names, the Saint Valentine ant. Members of this genus are also known as cocktail ants because of their habit of raising their abdomens when alarmed. Most species are arboreal (tree-dwelling). These ants are sometimes known as acrobat ants. Acrobat ants acquire food largely through predation on other insects, such as wasps.Schatz, Bertrand, and Martine Hossaert-Mckey. "Interactions of the Ant Crematogaster Scutellaris with the Fig/fig Wasp Mutualism." Ecological Entomology 28.3 (2003): 359-68. Print. They use venom to stun their prey and a complex trail-laying process to lead comrades to food sources. Like most ants, ''Crematogaster'' species reproduce by partaking in nuptial flights, where the queen acquires the sperm used to fertilize every egg throughout her life.

Parabiosis
Parabiosis, meaning "living beside", is a laboratory technique to study physiology. It combines two living organisms which are joined surgically to develop a single, shared physiological system. Parabiosis is used in the study of areas such as obesity, biological aging, stem cell research, tissue regeneration, diabetes, organ transplantation, tumor biology, and endocrinology. It can also describe a communal ecology of separate species of ants in colonies. Physiology Parabiotic experiments Parabiosis combines two living organisms which are joined surgically and develop single, shared physiological systems. Researchers can prove that the feedback system in one animal is circulated and affects the second animal via blood and plasma exchange. Parabiotic experiments were pioneered by Paul Bert in the mid-1800s. He postulated that surgically connected animals could share a circulatory system. Bert was awarded the Prize of Experimental Physiology of the French Academy of Science in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polygyny
Polygyny (; from Neoclassical Greek πολυγυνία (); ) is the most common and accepted form of polygamy around the world, entailing the marriage of a man with several women. Incidence Polygyny is more widespread in Africa than in any other continent. Some scholars see the slave trade's impact on the male-to-female sex ratio as a key factor in the emergence and fortification of polygynous practices in regions of Africa. Polygyny is most common in a region known as the "polygamy belt" in West Africa and Central Africa, with the countries estimated to have the highest polygamy prevalence in the world being Burkina Faso, Mali, Gambia, Niger and Nigeria. In the region of sub-Saharan Africa, polygyny is common and deeply rooted in the culture, with 11% of the population of sub-Saharan Africa living in such marriages (25% of the Muslim population and 3% of the Christian population, as of 2019). Polygyny is especially widespread in West Africa, with the countries estimated to h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ant Garden
An ant garden is a mutualistic interaction between certain species of arboreal ants and various epiphytic plants. It is a structure made in the tree canopy by the ants that is filled with debris and other organic matter in which epiphytes grow. The ants benefit from this arrangement by having a stable framework on which to build their nest while the plants benefit by obtaining nutrients from the soil and from the moisture retained there. Description Epiphytes are common in tropical rain forest and in cloud forest. An epiphyte normally derives its moisture and nutrients from the air, rain, mist and dew. Nitrogenous matter is in short supply and the epiphytes benefit significantly from the nutrients in the ant garden. The ant garden is made from "carton", a mixture of vegetable fibres, leaf debris, refuse, glandular secretions and ant faeces. The ants use this material to build their nests among the branches of the trees, to shelter the hemipteran insects that they tend in order to ...
