Allacma is a genus of arthropods belonging to the family Sminthuridae. [1]
The genus was first described by Börner in 1906. [1]
The species of this genus are found in Europe and Northern America. [1]
Selected species: [1]
Ticks are parasitic arachnids that are part of the mite superorder Parasitiformes. Adult ticks are approximately 3 to 5 mm in length depending on age, sex, species, and "fullness". Ticks are external parasites, living by feeding on the blood of mammals, birds, and sometimes reptiles and amphibians. The timing of the origin of ticks is uncertain, though the oldest known tick fossils are from the Cretaceous period, around 100 million years old. Ticks are widely distributed around the world, especially in warm, humid climates.
Tsuga is a genus of conifers in the subfamily Abietoideae of Pinaceae, the pine family. The common name hemlock is derived from a perceived similarity in the smell of its crushed foliage to that of the unrelated plant poison hemlock. Unlike the latter, Tsuga species are not poisonous.
Arbovirus is an informal name for any virus that is transmitted by arthropod vectors. The term arbovirus is a portmanteau word. Tibovirus is sometimes used to more specifically describe viruses transmitted by ticks, a superorder within the arthropods. Arboviruses can affect both animals and plants. In humans, symptoms of arbovirus infection generally occur 3–15 days after exposure to the virus and last three or four days. The most common clinical features of infection are fever, headache, and malaise, but encephalitis and viral hemorrhagic fever may also occur.
Hepatozoon is a genus of Apicomplexa alveolates which incorporates over 300 species obligate intraerythrocytic parasites. Species have been described from all groups of tetrapod vertebrates, as well as a wide range of haematophagous arthropods, which serve as both the vectors and definitive hosts of the parasite. By far the most biodiverse and prevalent of all haemogregarines, the genus is distinguished by its unique reciprocal trophic lifecycle which lacks the salivary transmission between hosts commonly associated with other apicomplexans. While particularly prevalent in amphibians and reptiles, the genus is more well known in veterinary circles for causing a tick-borne disease called hepatozoonosis in some mammals.
Cynopterus is a genus of megabats. The cynopterine section is represented by 11 genera, five of which occur in Malaysia, namely, Chironax, Balionycteris, Penthetor, Dyacopterus, and Cynopterus. About 30 names for Cynopterus species have been proposed, but only 16 are taxonomically valid forms.
Relapsing fever is a vector-borne disease caused by infection with certain bacteria in the genus Borrelia, which is transmitted through the bites of lice or soft-bodied ticks.
Ixodes ricinus, the castor bean tick, is a chiefly European species of hard-bodied tick. It may reach a length of 11 mm (0.43 in) when engorged with a blood meal, and can transmit both bacterial and viral pathogens such as the causative agents of Lyme disease and tick-borne encephalitis.
The family Neanuridae contains pudgy short-legged springtails of the order Poduromorpha. It was established by Carl Börner in 1901.
Sminthuridae is a family of springtails of the order Symphypleona. Sminthurids are commonly referred to as globular springtails.
Allacma fusca is a species of springtail. This species is endemic to western areas of Continental Europe and the British Isles, where it lives in the surface layers of the soil in moist habitats such as among leaf litter.
Rickettsia felis is a species of bacterium, the pathogen that causes cat-flea typhus in humans, also known as flea-borne spotted fever. Rickettsia felis also is regarded as the causative organism of many cases of illnesses generally classed as fevers of unknown origin in humans in Africa.
Nolina nelsonii, often misspelled Nolina nelsoni, is a flowering plant in the genus Nolina. The species was first described in 1906; in its genus, it is morphologically most similar to Nolina parryi. This extremely drought-tolerant plant is native to the deserts and montane regions in the State of Tamaulipas in northern/northeastern Mexico. It is known to be cold-hardy to at least −12 °C. It develops a trunk measuring from one to several meters high, making it an arborescent member of its genus. The bluish-green leaves, with finely toothed margins, are borne in dense rosettes, each with up to several hundred stiff linear (narrow) leaves up to 70 centimeters long. It is dioecious; upon reaching sexual maturity, its white-flowered inflorescence appears in Spring. The fruit capsules are around 80 mm in length, containing light-brown, spherical to oblong seeds 2–3 mm in diameter. After blooming, the plant's main trunk dies and multiple lateral trunks emerge to take its place.
Noeggerathia is an extinct genus of noeggerathialean plant that lived during the Late Carboniferous and Early Permian periods.
Gliocladium is an asexual fungal genus in the Hypocreaceae. Certain other species including Gliocladium virens were recently transferred to the genus Trichoderma and G. roseum became Clonostachys rosea f. rosea in the Bionectriaceae. Gliocladium is a mitosporic, filamentous fungus. Species of Gliocladium rarely produce a sexual state. Most pathogenic, disease-causing fungi in humans are mitosporic like Gliocladium. Gliocladium is filamentous; it grows tubular, elongated, and thread-like. It can be considered a contaminant.
Dicyrtomidae is a family of Collembola in the order Symphypleona, and it is the only family of the superfamily Dicyrtomoidea. It includes more than 200 species in eight genera.
Heteromurus is a genus of slender springtails in the family Entomobryidae. There are at least three described species in Heteromurus.
Cyphoderus is a genus of elongate-bodied springtails in the family Paronellidae. There are more than 20 described species in Cyphoderus.
Sabinaria magnifica is a species of palm tree and the only member of the genus Sabinaria. Native to the Darién Gap on the border between Colombia and Panama, it grows from 1 to 6 metres tall with large, deeply-divided leaf blades. It has been described as "striking", "spectacular" and "beautiful" by taxonomists.
Harzia is a genus of seed-borne fungus that occurs in the soil. It has been categorized in the Ceratostomataceae family. The genus Harzia originally contained three accepted species: Harzia acremonioides, Harzia verrucose, and Harzia velatea. Within the genus Harzia, Harzia acremonioides is one of the most common species that can be found in all climate regions around the world.
