Montrichardia
''Montrichardia'' is a genus of flowering plants in the family Araceae. It contains two species, '' Montrichardia arborescens'' and '' Montrichardia linifera'', and one extinct species '' Montrichardia aquatica''. The genus is helophytic and distributed in tropical America (West Indies, Belize, Brazil, Colombia, Costa Rica, French Guiana, Guatemala, Guyana, Honduras, Nicaragua, Panama, Peru, Puerto Rico, Suriname, Trinidad, Tobago, and Venezuela). The extinct species ''M. aquatica'' is known from fossils found in a Neotropical rainforest environment preserved in the Paleocene Cerrejón Formation of Colombia. Living ''Montrichardia'' species have a diploid chromosome number of 2n=48. Species *†'' Montrichardia aquatica'' Herrera - Colombia in Paleocene *'' Montrichardia arborescens'' (L.)

Taylor & Francis
Taylor & Francis Group is an international company originating in England that publishes books and academic journals. Its parts include Taylor & Francis, Routledge, F1000 Research or Dovepress. It is a division of Informa plc, a United Kingdom–based publisher and conference company. Overview The company was founded in 1852 when William Francis joined Richard Taylor in his publishing business. Taylor had founded his company in 1798. Their subjects covered agriculture, chemistry, education, engineering, geography, law, mathematics, medicine, and social sciences. Francis's son, Richard Taunton Francis (1883–1930), was sole partner in the firm from 1917 to 1930. In 1965, Taylor & Francis launched Wykeham Publications and began book publishing. T&F acquired Hemisphere Publishing in 1988, and the company was renamed Taylor & Francis Group to reflect the growing number of imprints. Taylor & Francis left the printing business in 1990, to concentrate on publishing. In 1998 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electropodagrion
''Electropodagrion'' is an extinct species of damselfly in the family Megapodagrionidae known from a fossil found in Europe. The genus contains a single described species, ''Electropodagrion szwedoi''. History and classification ''Electropodagrion'' is known from a solitary fossil, which is an inclusion in a transparent chunk of Baltic amber. The amber was recovered from fossil bearing rocks in the Baltic Sea region of Europe. Estimates of the age date between 37 million years old, for the youngest sediments and 48 million years old. This age range straddles the middle Eocene, ranging from near the beginning of the Lutetian to the beginning of the Pribonian. At the time of study, the holotype was part of the paleoentomology collections housed by the Museum of Amber Inclusions, University of Gdańsk, in Gdańsk, Poland. It was first studied by paleoentomologists Dany Azar of the Lebanese University and André Nel of the Muséum National d’Histoire Naturelle. Their 2008 ty ...

Dolichoderus Punctatus BMNHP-II1101 Profile
''Dolichoderus'' is a genus of ants found worldwide. Taxonomy The ants of the Neotropical genus ''Monacis'' were revised in 1959 by Kempf. However, Brown in 1973 and G. C. Wheeler and J. Wheeler in 1973 and 1976 considered both ''Monacis'' and ''Hypoclinea'' to be junior synonyms of ''Dolichoderus''. Description The type species is ''Dolichoderus attelaboides''. Worker ants in this genus have a body length that is typically about four millimetres and can be recognised by their thick, inflexible and strongly sculptured integument. There is a flange on the underside of the head near the base of the mandibles which is saw-like in some species. The longitudinal suture in the central plate of the metathorax is deeply impressed. The propodeum or first abdominal segment has the posterior face distinctly concave when viewed from the side. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dolichoderinae
Dolichoderinae is a subfamily of ants, which includes species such as the Argentine ant (''Linepithema humile''), the erratic ant, the odorous house ant, and the cone ant. The subfamily presents a great diversity of species throughout the world, distributed in different biogeographic realms, from the Palearctic, Nearctic, Afrotropical region and Malaysia, to the Middle East, Australian, and Neotropical regions. This subfamily is distinguished by having a single petiole (no post-petiole) and a slit-like orifice, from which chemical compounds are released. Dolichoderine ants do not possess a sting, unlike ants in some other subfamilies, such as Ponerinae and Myrmicinae, instead relying on the chemical defensive compounds produced from the anal gland. Of the compounds produced by dolichoderine ants, several terpenoids were identified including the previously unknown iridomyrmecin, isoiridomyrmecin, and iridodial. Such compounds are responsible for the smell given off by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Formicinae
The Formicinae are a subfamily within the Formicidae containing ants of moderate evolutionary development. Formicines retain some primitive features, such as the presence of cocoons around pupae, the presence of ocelli in workers, and little tendency toward reduction of palp or antennal segmentation in most species, except subterranean groups. Extreme modification of mandibles is rare, except in the genera '' Myrmoteras'' and '' Polyergus''. However, some members show considerable evolutionary advancement in behaviors such as slave-making and symbiosis with root-feeding hemipterans. Finally, all formicines have very reduced stings and enlarged venom reservoirs, with the venom gland, specialized (uniquely among ants) for the production of formic acid. All members of the Formicinae "have a one-segmented petiole in the form of a vertical scale". Identification Formicine ants have a single node-like or scale-like petiole (postpetiole entirely lacking) and the apex of ...

Stylocellidae
The Stylocellidae are a family of harvestmen with about 30 described species, all of which occur from India to New Guinea. Members of this family are from one to seven millimeters long. While ''Stylocellus'' species have eyes, these are absent in the other two genera. (2007): Stylocellidae. Hansen & Sørensen, 1904. In: Pinto-da-Rocha ''et al.'' 2007: 104ff Name The name of the type genus is combined from Ancient Greek ''stylos'' "pillar" and Latin ''ocellus'' "eye", referring to the elongated shape of the animal, compared to Sironidae, and the presence of eyes.

Burmese Amber
Burmese amber, also known as Burmite or Kachin amber, is amber from the Hukawng Valley in northern Myanmar. The amber is dated to around 100 million years ago, during the latest Albian to earliest Cenomanian ages of the mid-Cretaceous period. The amber is of significant palaeontological interest due to the diversity of flora and fauna contained as inclusions, particularly arthropods including insects and arachnids but also birds, lizards, snakes, frogs and fragmentary dinosaur remains. The amber has been known and commercially exploited since the first century AD, and has been known to science since the mid-nineteenth century. Research on the deposit has attracted controversy due to its alleged role in funding internal conflict in Myanmar and hazardous working conditions in the mines where it is collected. Geological context, depositional environment and age The amber is found within the Hukawng Basin, a large Cretaceous-Cenozoic sedimentary basin within northern Myanmar. The s ...
