Temnothorax Nylanderi
''Temnothorax nylanderi'' is a species of ant in the genus ''Temnothorax ''Temnothorax'' is a genus of ants in the subfamily Myrmicinae. It contains more than 380 species. Biology The workers of ''Temnothorax'' species are generally small. Colonies are typically monogynous, although facultative polygyny has been doc ...''. The species is found in western Europe. It was first described by Förster (1850) based on a male from Germany. Subspecies *''Temnothorax nylanderi nylanderonigriceps'' (Stitz, 1939) Ecology ''Temnothorax nylanderi'' lives in the litter, and nests can be found in small cavities in twigs and acorns for example. Nests usually contain less than 400 individuals, among them a single queen. Study shows that if these ants live socially isolated, their interaction with their colony members decreases and their stress response changes. Repartition ''Temnothorax nylanderi'' is widely distributed across Western Europe, and a parapatric species (''Temnothorax cras ...

Georg Forster
Johann George Adam Forster, also known as Georg Forster (, 27 November 1754 – 10 January 1794), was a German naturalist, ethnologist, travel writer, journalist and revolutionary. At an early age, he accompanied his father, Johann Reinhold Forster, on several scientific expeditions, including James Cook's second voyage to the Pacific. His report of that journey, ''A Voyage Round the World'', contributed significantly to the ethnology of the people of Polynesia and remains a respected work. As a result of the report, Forster, who was admitted to the Royal Society at the early age of twenty-two, came to be considered one of the founders of modern scientific travel literature. After returning to continental Europe, Forster turned toward academia. He taught natural history at the Collegium Carolinum in the Ottoneum, Kassel (1778–84), and later at the Academy of Vilna (Vilnius University) (1784–87). In 1788, he became head librarian at the University of Mainz. Most of his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temnothorax
''Temnothorax'' is a genus of ants in the subfamily Myrmicinae. It contains more than 380 species. Biology The workers of ''Temnothorax'' species are generally small. Colonies are typically monogynous, although facultative polygyny has been documented in several species. Colony populations are usually quite small, often with less than 100 workers. However, several studies have found colonies of some species to be widely dispersed with several to many satellite nests. Many species are arboreal, living within hollow stems, old beetle or termite galleries, or in galls. ''Temnothorax'' species appear to be trophic generalists, feeding on a wide variety of scavenged items, including the elaiosomes of seeds. None have been documented to be active or aggressive predators. Phylogenetics Recent molecular phylogenetic studies show that the genera ''Chalepoxenus'', ''Myrmoxenus'' and ''Protomognathus'' are nested within ''Temnothorax'', and that the latter is distinct from the more distant ...

Parapatric Speciation
In parapatric speciation, two subpopulations of a species evolve reproductive isolation from one another while continuing to exchange genes. This mode of speciation has three distinguishing characteristics: 1) mating occurs non-randomly, 2) gene flow occurs unequally, and 3) populations exist in either continuous or discontinuous geographic ranges. This distribution pattern may be the result of unequal dispersal, incomplete geographical barriers, or divergent expressions of behavior, among other things. Parapatric speciation predicts that hybrid zones will often exist at the junction between the two populations. In biogeography, the terms parapatric and parapatry are often used to describe the relationship between organisms whose ranges do not significantly overlap but are immediately adjacent to each other; they do not occur together except in a narrow contact zone. Parapatry is a geographical distribution opposed to sympatry (same area) and allopatry or peripatry (two simila ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anomotaenia Brevis
''Anomotaenia brevis'' is a tapeworm which has been found to be one of many parasite species able to manipulate their host's behavior. Host manipulation is commonly observed in parasites with complex life cycles reliant on multiple hosts for development. While the definitive host for ''A. brevis'' is the woodpecker, their intermediate host is the ''Temnothorax'' ''nylanderi'', a species of ant located in the oak forests of western Europe. The tapeworm alters the appearance and behavior of the ''T. nylanderi'' ant in order to ensure transmission to the woodpecker, where it can complete its life cycle. The tapeworm affects the behavior, life history, and morphology of the ''T. nylanderi'' ant, as well as indirectly affects its uninfected nest-mates. The ant larva is infected after feeding on bird faeces contaminated with ''A. brevis'' eggs. The tapeworm penetrates the ant's gut wall and develops into a cysticercoid within the haemocoel ...

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 an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hymenoptera Of Europe
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
