Mycocepurus
''Mycocepurus'' is a Neotropical genus of fungus-growing ants (tribe Attini) in the subfamily Myrmicinae. The genus is known from Mexico, south to Brazil and Argentina. Like other attines, they primarily grow fungi of the tribe Leucocoprini (family Agaricaceae). They use many different substrates for growing their fungi, from dry leaves and caterpillar dung to fruit matter. One of its species, ''Mycocepurus smithii'', which lives in South America, reproduces by cloning – all ants in a colony are clones of the queen. ''M. castrator'' is a parasite of ''M. goeldii''.

Mycocepurus Smithii
''Mycocepurus smithii'' is a species of fungus-growing ant from Latin America. This species is widely distributed geographically and can be found from Mexico in the north to Argentina in the south, as well as on some Caribbean Islands. It lives in a variety of forested habitats and associated open areas. Two studies published in 2009 demonstrated that some populations of the species consist exclusively of females which reproduce via thelytokous parthenogenesis. * A detailed study found evidence of sexual reproduction in some populations in the Brazilian Amazon. Accordingly, ''M. smithii'' consists of a mosaic of sexually and asexually reproducing populations. In asexual populations all ants in a single colony are female clones of the queen. Inside the colony, the ants cultivate a garden of fungus grown with pieces of dead vegetable matter, dead insects, and insect droppings.

Mycocepurus Goeldii
''Mycocepurus goeldii'' is a species of ant in the genus ''Mycocepurus''. The species is parasitised by a closely related species, ''Mycocepurus castrator''. The two diverged recently, around 37,000 years ago, and evolved in the same geographic region, making the parasite–host pair an example of sympatric speciation. ''M. castrator'' is directly descended from ''M. goeldii'', its host. Such relationships are not uncommon among social parasites, as recognized by Emery's rule. Less common are cases like ''M. castrators, where two species diverge without the benefit of geographic isolation, known as sympatric speciation. Rabeling ''et al.'' (2014) analyzed divergence of mitochondrial versus nuclear DNA, finding that the nuclear alleles bore more similarities than the mitochondrial alleles. This led them to rule out the possibility of recent interbreeding, and conclude that sympatric speciation had occurred. The two species are believed to have diverged around 37,000 years ag ...

Mycocepurus Castrator
''Mycocepurus castrator'' is a species of parasitic ant, in the genus ''Mycocepurus'', native to Brazil. Described in 2010, the species is a workerless and obligate parasite of the related ant ''Mycocepurus goeldii''. It is known only from Rio Claro, Brazil, and has only been found in nests of ''M. goeldii''. ''M. castrator'' and its host are closely related and diverged recently, around 37,000 years ago. They evolved in the same geographic region, making the parasite–host pair an example of sympatric speciation. The species is the first inquiline known among the lower attines. Etymology Because ''M. goeldii'' nests that host ''M. castrator'' appear to only produce sterile workers, the species has been named " castrator" in reference to that. Description ''M. castrator'' is a relatively minuscule species, with the average wing length being about 1.07–1.23 millimeters. The head is rectangular in shape, measuring about 0.6 millimeters across the face. The antennae consist o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungus-growing Ants
Fungus-growing ants (tribe Attini) comprise all the known fungus-growing ant species participating in ant–fungus mutualism. They are known for cutting grasses and leaves, carrying them to their colonies' nests, and using them to grow fungus on which they later feed. Their farming habits typically have large effects on their surrounding ecosystem. Many species farm large areas surrounding their colonies and leave walking trails that compress the soil, which can no longer grow plants. Attine colonies commonly have millions of individuals, though some species only house a few hundred. They are the sister group to the subtribe Dacetina. Leafcutter ants, including ''Atta'' and '' Acromyrmex'', make up two of the genera. Their cultivars mostly come from the fungal tribe Leucocoprineae of family Agaricaceae. Attine gut microbiota is often not diverse due to their primarily monotonous diets, leaving them at a higher risk than other beings for certain illnesses. They are especially ...

Myrmicinae
Myrmicinae is a subfamily of ants, with about 140 extant genera; their distribution is cosmopolitan. The pupae lack cocoons. Some species retain a functional sting. The petioles of Myrmicinae consist of two nodes. The nests are permanent and in soil, rotting wood, under stones, or in trees.Goulet, H & Huber, JT (eds.) (1993) Hymenoptera of the world: an identification guide to families. Agriculture Canada. p. 224 Identification Myrmicine worker ants have a distinct postpetiole, i.e., abdominal segment III is notably smaller than segment IV and set off from it by a well-developed constriction; the pronotum is inflexibly fused to the rest of the mesosoma, such that the promesonotal suture is weakly impressed or absent, and a functional sting is usually present. The clypeus is well-developed; as a result, the antennal sockets are well separated from the anterior margin of the head. Most myrmicine genera possess well-developed eyes and frontal lobes that partly conceal the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auguste Forel
Auguste-Henri Forel (1 September 1848 – 27 July 1931) was a Swiss myrmecologist, neuroanatomist, psychiatrist and eugenicist, notable for his investigations into the structure of the human brain and that of ants. For example, he is considered a co-founder of the neuron theory. Forel is also known for his early contributions to sexology and psychology. From 1978 until 2000 Forel's image appeared on the 1000 Swiss franc banknote. Biography Born in villa ''La Gracieuse'', Morges, Switzerland, to Victor Forel a pious Swiss Calvinist and Pauline Morin, a French Huguenot he was brought up under a protective household. At the age of seven he began to take an interest in insects. He went to school at Morges and Lausanne before joining the medical school at Zurich. Forel had a diverse and mixed career as a thinker on many subjects. At Zurich he was inspired by the work of Bernhard von Gudden (1824-1886). In 1871 he went to Vienna and studied under Theodor Meynert (1833-1892) but w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Daily Telegraph
''The Daily Telegraph'', known online and elsewhere as ''The Telegraph'', is a national British daily broadsheet newspaper published in London by Telegraph Media Group and distributed across the United Kingdom and internationally. It was founded by Arthur B. Sleigh in 1855 as ''The Daily Telegraph & Courier''. Considered a newspaper of record over ''The Times'' in the UK in the years up to 1997, ''The Telegraph'' generally has a reputation for high-quality journalism, and has been described as being "one of the world's great titles".

Ant Genera
Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from vespoid wasp ancestors in the Cretaceous period. More than 13,800 of an estimated total of 22,000 species have been classified. They are easily identified by their geniculate (elbowed) antennae and the distinctive node-like structure that forms their slender waists. Ants form colonies that range in size from a few dozen predatory individuals living in small natural cavities to highly organised colonies that may occupy large territories and consist of millions of individuals. Larger colonies consist of various castes of sterile, wingless females, most of which are workers (ergates), as well as soldiers (dinergates) and other specialised groups. Nearly all ant colonies also have some fertile males called "drones" and one or more fertile females called " queens" ( gynes). The colonies are described as superorganisms because the ...
