Electromyrmex Klebsi IGRBA010 Profile
''Electromyrmex'' is an extinct genus of ants in the formicid subfamily Dolichoderinae. The genus contains a single described species, ''Electromyrmex klebsi'' and is known from a group of Middle Eocene fossils which were found in Europe. History and classification ''Electromyrmex'' is known from several fossil specimens of adult workers. A worker was first discovered preserved as an inclusion in a transparent chunk of Baltic amber, and additional workers have been identified from Baltic amber found in Lithuania. Workers of an undescribed species labeled as "''Electromyrmex'' sp A" have been found in Bitterfeld amber. Baltic amber is approximately forty six million years old, having been deposited during Lutetian stage of the Middle Eocene. There is debate on what plant family the amber was produced by, with macrofossil and microfossil evidence suggesting a ''Pinus'' relative, while chemical and spectroscopic evidence suggests ''Agathis'' or ''Sciadopitys''.

William Morton Wheeler
William Morton Wheeler (March 19, 1865 – April 19, 1937) was an American entomologist, myrmecologist and professor at Harvard University. Biography Early life and education William Morton Wheeler was born on March 19, 1865, to parents Julius Morton Wheeler and Caroline Georgiana Wheeler ( Anderson) in Milwaukee, Wisconsin. At a young age, Wheeler had an interest in natural history, first being when he observed a moth ensnared in a spiders web; such observation interested Wheeler that he became importunate for more nature lore. Wheeler attended public school, but, due to "persistently bad behavior", he was transferred to a local German academy which was known for its extreme discipline. After he completed his courses in the German academy, he attended a German normal school. In both institutions, Wheeler was trained in a variety of subjects: he was given training in languages, philosophy and science. By this time, he could read fluently in French, German, Greek, Italian, Lati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tetraponera
''Tetraponera'' is a genus of ants in the subfamily Pseudomyrmecinae that are commonly known as slender ants and are characterized by their arboreal nature and slender bodies. The 96 described species of ''Tetraponera'' all of which live in hollow structures of plants and trees, such as thorns or branches; these hosts are known as myrmecophytes. ''Tetraponera'' species are closely related to the New World genus of ants '' Pseudomyrmex'', but differ in their relationships with host plants. Mutualisms and behaviour ''Tetraponera'' species are generally defined by the myrmecophytes they inhabit and the mutualistic relationship they share. These host plants always have hollow thorns or branches in which the ants can live and form a colony. Also, the myrmecophytes provide energy rich food sources such as extrafloral nectar and/or food bodies. All ''Tetraponera'' species have gut symbionts that allow them to digest amino acid-deficient food provided by their host plants; these gut ...

Pseudomyrma
''Pseudomyrmex'' is a genus of stinging, wasp-like ants in the subfamily Pseudomyrmecinae. They are large-eyed, slender ants, found mainly in tropical and subtropical regions of the New World. Distribution and habitat ''Pseudomyrmex'' is predominantly Neotropical in distribution, but a few species are known from the Nearctic region. Most species are generalist twig nesters, for instance, '' Pseudomyrmex pallidus'' may nest in the hollow stems of dead grasses, twigs of herbaceous plants, and in dead, woody twigs. However, the genus is best known for several species that are obligate mutualists with certain species of ''Acacia''. Other species have evolved obligate mutualism with other trees; for example '' Pseudomyrmex triplarinus'' is obligately dependent on any of a few trees in the genus ''Triplaris''.Larrea-Alcázar, D. M. and J. A. Simonetti. (2007)Why are there few seedlings beneath the myrmecophyte ''Triplaris americana''?. ''Acta Oecologica'' 32(1) 112–18. ...

Arboreal
Arboreal locomotion is the locomotion of animals in trees. In habitats in which trees are present, animals have evolved to move in them. Some animals may scale trees only occasionally (scansorial), but others are exclusively arboreal. The habitats pose numerous mechanical challenges to animals moving through them and lead to a variety of anatomical, behavioral and ecological consequences as well as variations throughout different species. Cartmill, M. (1985). "Climbing". pp. 73–88 ''In'': Hildebrand, Milton; Bramble, Dennis M.; Liem, Karel F.; Wake, David B. (editors) (1985). ''Functional Vertebrate Morphology''. Cambridge, Massachusetts: Belknap Press. 544 pp. . Furthermore, many of these same principles may be applied to climbing without trees, such as on rock piles or mountains. Some animals are exclusively arboreal in habitat, such as tree snails. Biomechanics Arboreal habitats pose numerous mechanical challenges to animals moving in them, which have been solved in ...

Incertae Sedis
or is a term used for a taxonomy (biology), taxonomic group where its broader relationships are unknown or undefined. Alternatively, such groups are frequently referred to as "enigmatic taxa". In the system of open nomenclature, uncertainty at specific taxonomic levels is indicated by (of uncertain family), (of uncertain suborder), (of uncertain order) and similar terms. Examples * The fossil plant ''Paradinandra, Paradinandra suecica'' could not be assigned to any family, but was placed ''incertae sedis'' within the order Ericales when described in 2001. * The fossil ''Gluteus minimus (fossil), Gluteus minimus'', described in 1975, could not be assigned to any known animal phylum. The genus is therefore ''incertae sedis'' within the kingdom Animalia. * While it was unclear to which order the New World vultures (family Cathartidae) should be assigned, they were placed in Aves ''incertae sedis''. It was later agreed to place them in a separate order, Cathartiformes. * Boc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Myrmicinae is a subfamily In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end botanical subfamily names with "-oideae", and zo ... 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.)

University Of Rennes 1
The University of Rennes 1 was a public university located in Rennes, France. It was founded in 1970, after splitting of the historic University of Rennes into two universities. On January 1, 2023, the University of Rennes 1 merged with five grandes écoles: EHESP, Ecole des Hautes Etudes en Santé Publique, École nationale supérieure de chimie de Rennes, ENS Rennes, INSA Rennes and Institut d'études politiques de Rennes, Sciences-Po Rennes to create the new University of Rennes. History Creation of the University of Brittany Asked by Francis II, Duke of Brittany, the Pope created the first university of Brittany in Nantes in 1460. It taught arts, medicine, law, and theology. In 1728, the mayor of Nantes, Gérard Mellier, asked that the university be moved to Rennes, which was more trade orientated already had the Parliament of Brittany. The law school was moved the Rennes in 1730. In 1793 the French Revolution closed all universities and it was not before 1806 that the Law s ...
