Nylanderia Pygmaea
''Nylanderia pygmaea'' is an extinct species of formicid in the ant subfamily Formicinae known from fossils found in the Baltic region. History and classification When described ''N. pygmaea'' was known from twenty males and two queen fossils which were fossilized as inclusions in transparent chunks of Baltic amber almost all of which are now presumed lost. Additional individuals of all castes have since been found in Baltic, Bitterfeld, Rovno, and Scandinavian amber. Baltic amber is approximately forty six million years old, having been deposited during Lutetian stage of the Middle Eocene. There is debate on by what plant family the amber was produced, with macrofossil and microfossil evidence suggesting a ''Pinus'' relative, while chemical and spectroscopic evidence suggests ''Agathis'' or ''Sciadopitys''. The paleoenvironment of the Eocene Baltic forests where the ''P. eocenicum'' lived was that of humid temperate to subtropical islands. The forests were composed of most ...

Extinct
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ukraine
Ukraine ( uk, Україна, Ukraïna, ) is a country in Eastern Europe. It is the second-largest European country after Russia, which it borders to the east and northeast. Ukraine covers approximately . Prior to the ongoing Russian invasion, it was the eighth-most populous country in Europe, with a population of around 41 million people. It is also bordered by Belarus to the north; by Poland, Slovakia, and Hungary to the west; and by Romania and Moldova to the southwest; with a coastline along the Black Sea and the Sea of Azov to the south and southeast. Kyiv is the nation's capital and largest city. Ukraine's state language is Ukrainian; Russian is also widely spoken, especially in the east and south. During the Middle Ages, Ukraine was the site of early Slavic expansion and the area later became a key centre of East Slavic culture under the state of Kievan Rus', which emerged in the 9th century. The state eventually disintegrated into rival regional po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ponerinae
Ponerinae is a subfamily of ants in the Poneromorph subfamilies group, with about 1,600 species in 47 extant genera, including ''Dinoponera gigantea'' - one of the world's largest species of ant. Mated workers have replaced the queen as the functional egg-layers in several species of ponerine ants. In such queenless species, the reproductive status of workers can only be determined through ovarian dissections. Description and identification They are most easily identified from other subfamilies by possessing a single-node petiole with a constriction before the second gastral segment. They are rare examples of stinging ants. In addition to the sting, they can also be characterized by a single segmented petiole and the constriction of the first and second segment of the gaster. They can also be identified by the shape of their head. Female workers have twelve segmented antennae, whereas male workers have 13 segmented antennae. Behavior These ants typically nest in soil, for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nylanderia
''Nylanderia'' is a large genus of ants in the subfamily Formicinae. The genus has a nearly cosmopolitan distribution with species inhabiting a wide array of habitats in almost all geographic regions. ''Nylanderia'', currently containing over 110 species, is an ecologically important genus, with some species reported as being invasive. The ants are small to medium in size and range in color from pale yellow to black. Taxonomy The genus was first described as a subgenus of ''Prenolepis'' by Emery (1906), a status he revised a couple of years later when he placed it as subgenus of ''Paratrechina'' (Emery, 1925). Wheeler (1936) raised ''Nylanderia'' to genus, where it remained until Brown (1973) provisionally placed it as a junior synonym of ''Paratrechina'', a status which was later confirmed by Trager (1984). ''Nylanderia'' was finally revived from synonymy and restored at the rank of genus by LaPolla, Brady & Shattuck (2010). Until 2010, most ''Nylanderia'' species were placed ...

Carlo Emery
Carlo Emery (25 October 1848, Naples – 11 May 1925) was an Italian entomologist. He is remembered for Emery's rule, which states that insect social parasitism (biology), social parasites are often closely related to their hosts. Early in his career Carlo Emery pursued a course in general medicine, and in 1872 narrowed his interests to ophthalmology. In 1878 he was appointed Professor of Zoology at the University of Cagliari, remaining there for several years until 1881 when he took up an appointment at the University of Bologna as Professor of Zoology, remaining there for thirty-five years until his death. Emery specialised in Hymenoptera, but his early work was on Coleoptera. Prior to 1869, his earliest works were a textbook of general zoology and papers on fishes and molluscs. From 1869 to 1925 he devoted himself almost entirely to the study of ants. Emery published extensively between 1869 and 1926 describing 130 genera and 1057 species mainly in Philogène Auguste Gali ...

William Morton Wheeler
William Morton Wheeler (March 19, 1865 – April 19, 1937) was an American entomologist, myrmecologist and Harvard professor. 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 University School of Milwaukee, 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, ...

Paratethys Sea
The Paratethys sea, Paratethys ocean, Paratethys realm or just Paratethys was a large shallow inland sea that stretched from the region north of the Alps over Central Europe to the Aral Sea in Central Asia. Paratethys was peculiar due to its paleogeography: it consisted of a series of deep basins, formed during the Oxfordian stage of the Late Jurassic as an extension of the rift that formed the Central Atlantic Ocean. These basins were connected with each other and the global ocean by narrow and shallow seaways that often limited water exchange and caused widespread long-term anoxia. Paratethys was at times reconnected with the Tethys or its successors (the Mediterranean Sea or the Indian Ocean) during the Oligocene and the early and middle Miocene times, but at the onset of the late Miocene epoch, the tectonically trapped sea turned into a megalake from the eastern Alps to what is now Kazakhstan. From the Pliocene epoch onward (after 5 million years ago), Paratethys bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
