Escovopsis
''Escovopsis'' is a genus of seven formally acknowledged parasitic microfungus species that rely on other fungi to be their hosts. This genus formally circumscribed with a single identified species in 1990; in 2013 three other species were added. In an early 2015 published study, scientists collected five species of ''Escovopsis'' from both genera of fungus-growing ants, ''Atta'' and ''Acromyrmex'', four of which came from ant colonies in Brazil and the fifth of which came from Trinidad. These ''Escovopsis'' species included '' E. moelleri'', '' E. microspora'', '' E. weberi'', '' E. lentecrescens'', and '' E. aspergilloides''. The research revealed another ''Escovopsis'' species ('' E. trichodermoides'') isolated and derived from the lower attine ant, ''Mycocepurus goeldii''. It was determined to be a species independent of the other five species because of its complex branch system and varying conidiophores, which lack typical swelling. A separate ...

Escovopsis Aspergilloides
''Escovopsis aspergilloides'' is a species of fungus that was rediscovered in 1995 by mycologists Keith A. Seifert, Robert A. Samson and Ignacio Chapela. Escovopsis aspergilloides co-exist in a symbiotic relationship with attini ants - fungus-growing ants. The highly evolved, ancient ant-fungus mutualism has become a model system in the study of symbiosis. In spite of this, the genus ''Escovopsis'' was not proposed until 1990 and the first two species were not formally described until the 1990s: ''E. weberi'' by Muchovej and Della Lucia in 1990 ''E. aspergilloides'' by Seifert, Samson and Chapela in 1995. Discovery ''E. aspergilloides'' was first discovered in 1893 by Alfred Moeller (Möller) in Blumenau on the island of Santa Catharina, Brazil - home of the German expatriate and naturalist, Fritz Müller - whose biography Moeller wrote. Alfred Moeller was undertaking a detailed study of local fungi for the Berlin Academy. His two-year field work in 1890 and 1891 resulted in his ...

Pseudonocardia
''Pseudonocardia'' is the type genus of the bacteria family Pseudonocardiaceae. Members of this genus have been found living mutualistically on the cuticle of the leafcutter ants because the bacteria has antibiotic properties that protect the fungus grown by the ants. When they are grooming, their legs are passed over their mouth gland (metapleural gland) that produces the antibiotic and then their legs touch the fungi while they are walking around. The ants have metapleural glands that produce the antimicrobial components to eliminate the ''Escovopsis'' fungi. The bacteria may also be found in crypts on the propleural plate. ''Pseudonocardia'' is found to have antibiotic properties provided to the leaf-cutter ant to inhibit the growth of ''Escovopsis'', which is a black yeast that parasitizes the leaf-cutter ant. ''Pseudonocardia'' can be found in both aquatic (including marine) and terrestrial ecosystems. ''Pseudonocardia'' belongs to the phylum ''Actinobacteria.'' Most ''Actinob ...

Acromyrmex
''Acromyrmex'' is a genus of New World ants of the subfamily Myrmicinae. This genus is found in South America and parts of Central America and the Caribbean Islands, and contains 33 known species. Commonly known as "leafcutter ants" they comprise one of the two genera of advanced attines within the tribe Attini, along with ''Atta''. Anatomy ''Acromyrmex'' species' hard outer covering, the exoskeleton or cuticle, functions as armour, protection against dangerous solar waves, an attachment base for internal muscles, and to prevent water loss. It is divided into three main parts; the head, thorax, and abdomen. A small segment between the thorax and abdomen, the petiole, is split into two nodes in ''Acromyrmex'' species. The antennae are the most important sense organs ''Acromyrmex'' species possess, and are jointed so the ant can extend them forward to investigate an object. It can retract them back over its head when in a dangerous situation, for example, a fight. ''Acromyrme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Costa Rica
The University of Costa Rica (Spanish: ''Universidad de Costa Rica,'' abbreviated UCR) is a public university in the Republic of Costa Rica, in Central America. Its main campus, Ciudad Universitaria Rodrigo Facio, is located in San Pedro Montes de Oca, in the province of San José. It is the oldest and largest institution of higher learning in Costa Rica, originally established as the ''Universidad de Santo Tomás'' in 1843. It is also the most important research university in the country and Central America and is counted among the most prestigious universities of Latin America. Approximately 45,000 students attend UCR throughout the year. History The first institution dedicated to higher education in Costa Rica was the ''University of Saint Thomas'' (''Universidad de Santo Tomás''), which was established in 1843. That institution maintained close ties with the Roman Catholic Church and was closed in 1888 by the progressive and anti-clerical government of President Ber ...

Fungi
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
