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 ...

Temnothorax Rugatulus
''Temnothorax rugatulus'' is a species of ant in the genus ''Temnothorax''. It is found in North America. More specifically, it is found in the forests of the western United States."Colony size does not predict foraging distance in the ant Temnothorax rugatulus: a puzzle for standard scaling models." Insectes Sociaux 60.1 (2013): 93-96. Colonies are either monogynous (with single reproductive queen) or polygynous (multiple queens). Queens in monogynous colonies are generally larger (marcogynes), about twice the size of conspecific workers; polygynous colonies have smaller queens (microgynes), typically slightly smaller than the workers. T. ''rugatulus'' ants are a subdominant ant group."Extraordinary starvation resistance in ''Temnothorax rugatulus'' (Hymenoptera, Formicidae) colonies: Demography and adaptive behavior." Insectes Sociaux 52.3 (2005): 282-290 Behavior Quorum decision making Temnothorax ''rugatulus'' ants are highly skilled in different consensus methods to help th ...

Temnothorax Pilagens
''Temnothorax pilagens'' (from Latin: ''pilare'', "to pluck", "plunder", "pillage") is a small Nearctic species of slave-making ant in the subfamily Myrmicinae. It occurs in northeastern United States. It raids the acorn castles of other insects ('' Temnothorax longispinosus'' and '' Temnothorax ambiguous'') and captures them as slaves and has been nicknamed the pillage ant. Habitat and distribution The species is known from the north-eastern parts of the United States and possibly south-eastern Canada. They live in forests, woodlands and parks. Preferentially wooded sites with little understory, and a high density of suitable nest sites, such as acorns, hickory nuts and sticks. Occurrence is patchy and depends on high density of suitable host populations; so far only known from three sites in the northern US: Niquette Bay State Park (Vermont), E.N. Huyck Preserve ( Rensselaerville, New York) and Sleeping Bear Dunes National Lakeshore (Empire, Michigan). In all three populatio ...

Temnothorax Nylanderi

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 ...

Temnothorax Albipennis
''Temnothorax albipennis'', the rock ant is a species of small ant in the subfamily Myrmicinae. It occurs in Europe and builds simple nests in rock crevices. Description This species has the typical ant body pattern of head, mesosoma and metasoma, with the first two segments of the metasoma forming a distinct waist. It is light brown and has a few short pale coloured hairs. The antennae are elbowed and there are a pair of compound eyes and three ocelli. Biology 180px, left, View of head from above As with other ants, there is a single, relatively large queen that lays eggs in the nest and a large number of workers. These are all non-breeding females and leave the nest to forage and collect building materials for its construction and repair. ''T. albipennis'' builds simple nests in cracks in rocks, enclosed by walls built from tiny pebbles and grains of sand. In an experiment where two sizes of sand grain were offered to ants that were foraging for building materials, the ants ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temnothorax Unifasciatus
''Temnothorax unifasciatus'' is a species of ant in the subfamily Myrmicinae. Behavior ''Temnothorax unifasciatus'' exhibit the altruistic behavior of social withdrawal, or “altruistic self-removal” whilst on the brink of death. Dying ants will leave their nest hours or in some cases days before their death. The behavior is exhibited both in the presence of fungal infection as well as when experimentally exposed to 95% , causing the ants to die in the absence of an acting pathogen. This indicates that the ants are in fact behaving in an altruistic manner, rather than experiencing behavioral manipulation as a result of pathogen influence. The action is altruistic because it reduces the risk of infecting other ants in the colony. This in turn minimizes the risk of transferring the infection to kin and thus likely results in a higher inclusive fitness In evolutionary biology, inclusive fitness is one of two metrics of evolutionary success as defined by W. D. Hamilton in 1964 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
