Rickia Wasmannii
''Rickia wasmannii'' is a species of the widely distributed entomoparasitic order of fungi Laboulbeniales. It is an obligatory ectoparasite of ants of the genus Myrmica. The thalli penetrate outer layer of the cuticle, and appear on the host body surface. Little is known about its effect on the host ant, but it is usually regarded as a rather neutral symbiont. Contrarily, however, a recent study has documented an increased need of drinking water and a shortened life-span of infected ants. The known host species of ''Rickia wasmannii'' are various ''Myrmica'' species, the most frequent being ''Myrmica scabrinodis''. The fungus was reported from many European countries such as Austria, Bulgaria, the Czech Republic, France, Germany, Hungary, Italy, Luxembourg, Slovakia, Slovenia, Spain, Switzerland, and the United Kingdom. In 2016, Pfiegler et al. showed that inquiline mites can become infected by ''R. wasmannii'', which was thought to be restricted to the genus ''Myrmica'' (Hymen ...

Acaridae
The Acaridae are a family of mites in order Sarcoptiformes. Distribution There are several acarid genera with cosmopolitan distributions, such as ''Acarus'''', Sancassania'' and ''Tyrophagus''. There are even ''Tyrophagus'' found in Antarctica and (spacecraft in) low Earth orbit. Ecology Acaridae live in various habitats and have various diets. Many are generalists that live in natural (e.g. soil, litter, animal nests, decomposing plant material) and artificial (e.g. human dwellings, granaries, greenhouses, plant nurseries) environments. They feed on decomposing organic material, fungi and nematodes. There are also more specialised acarids. Some ''Acarus'' inhabit nests of warm-blooded animals, mostly rodents and birds. Within ''Sancassania,'' there are species associated with certain bees, associated with scarabaeid beetles (riding phoretically on live beetles and feeding on dead beetles) or feeding on mushrooms. A lineage of ''Tyrophagus'', comprising ''T. formicetorum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myrmica Scabrinodis
''Myrmica scabrinodis'' is a Euro-Siberian species of ant. It lives in moderately humid habitats, tolerates soil moisture but also needs direct sunshine. It often inhabits peat bogs. It builds nests in the ground, in grass or moss tussocks, even under stones or in rotten wood. Its colonies are monogynous or have only a few queens and may contain about 2500 workers. This ant species is the main host of the entomopathogenic fungus '' Rickia wasmannii''. ''Phengaris'' caterpillars are primary threats of ''M. scabrinodis'' with specific species such as ''Phengaris arion The large blue (''Phengaris arion'') is a species of butterfly in the family Lycaenidae.

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] |
Ascomycota
Ascomycota is a phylum of the kingdom Fungi that, together with the Basidiomycota, forms the subkingdom Dikarya. Its members are commonly known as the sac fungi or ascomycetes. It is the largest phylum of Fungi, with over 64,000 species. The defining feature of this fungal group is the " ascus" (), a microscopic sexual structure in which nonmotile spores, called ascospores, are formed. However, some species of the Ascomycota are asexual, meaning that they do not have a sexual cycle and thus do not form asci or ascospores. Familiar examples of sac fungi include morels, truffles, brewers' and bakers' yeast, dead man's fingers, and cup fungi. The fungal symbionts in the majority of lichens (loosely termed "ascolichens") such as ''Cladonia'' belong to the Ascomycota. Ascomycota is a monophyletic group (it contains all descendants of one common ancestor). Previously placed in the Deuteromycota along with asexual species from other fungal taxa, asexual (or anamorphic) ascomyce ...

Laboulbeniomycetes
The Laboulbeniomycetes are a unique group of fungi that are obligatorily associated with arthropods, either as external parasites ( Herpomycetales and Laboulbeniales) or for dispersal ( Pyxidiophorales). Herpomycetales and Laboulbeniales fungi are minute; their fruiting bodies, referred to as ''thalli'', commonly measure less than one millimeter. They live on the antennae, the mouthparts or other body regions of their arthropod hosts. Although several species of Laboulbeniomycetes have more or less extensive, root-like hyphal systems (haustoria In botany and mycology, a haustorium (plural haustoria) is a rootlike structure that grows into or around another structure to absorb water or nutrients. For example, in mistletoe or members of the broomrape family, the structure penetrates th ...) inside their hosts, as a group these fungi are relatively harmless to their hosts.

Laboulbeniales
The Laboulbeniales is an order of Fungi within the class Laboulbeniomycetes. They are also known by the colloquial name beetle hangers or labouls. The order includes around 2,325 species of obligate insect ectoparasites that produce cellular thalli from two-celled ascospores. Of the described Laboulbeniales, Weir and Hammond 1997 find 80% to be from Coleoptera and the next largest group to be the 10% from Diptera. Recently, the genus '' Herpomyces'', traditionally considered a basal member of Laboulbeniales, was transferred to the order Herpomycetales based on molecular phylogenetic data. Laboulbeniales typically do not kill their hosts, although they may impair host fitness if the parasite density is high. Laboulbeniales form individual thalli, and lack vegetative hyphae. A thallus is attached to its host by a simple dark-colored foot cell, or a rhizoidal haustorium through which the fungus penetrates the exoskeleton of its host to draw nutrients from the hemolymph.

Rickia
''Rickia'' is a genus of fungi in the family Laboulbeniaceae. The genus contain 132 species. The genus name of ''Rickia'' is in honour of Johann Rick (known in Portuguese as João Evangelista Rick) (1869–1946), who was an Austrian-Brazilian teacher, clergyman and Botanist (Mycology). He taught Mathematics and Natural history between 1903-1915 at the Jesuit School in São Leopoldo, in Rio Grande do Sul in Brazil. The genus was circumscribed In geometry, the circumscribed circle or circumcircle of a polygon is a circle that passes through all the vertices of the polygon.

Myrmica
''Myrmica'' is a genus of ants within the subfamily Myrmicinae. It is widespread throughout the temperate regions of the Holarctic and high mountains in Southeast Asia. The genus consists of around 200 known species and additional subspecies, although this figure is likely to rise as soon as the Chinese and Nearctic fauna lists are revised. Inquilines The genus contains a number of inquiline species (commensal symbionts), other ''Myrmica'' species that manage to invade the nest of their host. Subsequently, they use hormones to manipulate the host colony in such a way that eggs of the host queen develop into workers, and parasite brood into sexuals. Hence, the parasite is not able to sustain a colony of its own, but uses host resources instead. Similarly, larvae of the butterfly genus '' Maculinea'' (a junior synonym of ''Phengaris'', family Lycaenidae) and of the southern armyworm, live inside ''Myrmica'' nests where they are either directly fed by ants or prey upon ant broo ...

Thalli
Thallus (plural: thalli), from Latinized Greek (), meaning "a green shoot" or "twig", is the vegetative tissue of some organisms in diverse groups such as algae, fungi, some liverworts, lichens, and the Myxogastria. Many of these organisms were previously known as the thallophytes, a polyphyletic group of distantly related organisms. An organism or structure resembling a thallus is called thalloid, thallodal, thalliform, thalline, or thallose. A thallus usually names the entire body of a multicellular non-moving organism in which there is no organization of the tissues into organs. Even though thalli do not have organized and distinct parts (leaves, roots, and stems) as do the vascular plants, they may have analogous structures that resemble their vascular "equivalents". The analogous structures have similar function or macroscopic structure, but different microscopic structure; for example, no thallus has vascular tissue. In exceptional cases such as the Lemnoideae, where t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chelicerata
The subphylum Chelicerata (from New Latin, , ) constitutes one of the major subdivisions of the phylum Arthropoda. It contains the sea spiders, horseshoe crabs, and arachnids (including Opiliones, harvestmen, scorpions, spiders, Solifugae, solifuges, Parasitiformes, ticks, and Acariformes, mites, among many others), as well as a number of extinct lineages, such as the eurypterids (sea scorpions) and chasmataspidids. The Chelicerata originated as marine animals in the Middle Cambrian period; the first confirmed chelicerate fossils, belonging to ''Sanctacaris'', date from Burgess Shale, 508 million years ago. The surviving marine species include the four species of xiphosurans (horseshoe crabs), and possibly the 1,300 species of Pycnogonida, pycnogonids (sea spiders), if the latter are indeed chelicerates. On the other hand, there are over 77,000 well-identified species of air-breathing chelicerates, and there may be about 500,000 unidentified species. Like all arth ...
