Multituberculata is an extinct taxon of rodent-like allotherian mammals that existed for approximately 166 million years, the longest fossil history of any mammal lineage. They eventually declined from the late Paleocene onwards, disappearing from the known fossil record in the late Eocene, though gondwanatheres lived into the Miocene, and may have been multituberculates. More than 200 species are known, ranging from mouse-sized to beaver-sized. These species occupied a diversity of ecological niches, ranging from burrow-dwelling to squirrel-like arborealism to jerboa-like hoppers. Multituberculates are usually placed as crown mammals outside either of the two main groups of living mammals—Theria, including placentals and marsupials, and Monotremata—but closer to Theria than to monotremes. Nonetheless, at least one study found a potential status as sister taxa to monotremes/Australosphenida.
Cambarus is a large and diverse genus of crayfish from the United States and Canada. The adults range in size from about 5 centimeters (2 in) up to approximately 15 centimeters (6 in).
As with other flowering plants, the taxonomy of Banksia has traditionally been based on anatomical and morphological properties of the Banksia flower, fruiting structure and seed, along with secondary characteristics such as leaf structure and growth habit. Increasingly, molecular evidence from DNA is providing important new insights into relationships within the genus and between this and other genera in the Proteaceae.
Banksia ser. Dryandroideae is a taxonomic series in the plant genus Banksia. First published by Carl Meissner in 1856, the name has had two circumscriptions. As presently circumscribed it is monotypic, containing only B. dryandroides.
Banksia sect. Banksia is one of four sections of Banksia subgenus Banksia. It contains those species of subgenus Banksia with straight or sometimes curved but not hooked styles. These species all have cylindrical inflorescences and usually exhibit a bottom-up sequence of flower anthesis. It is a widely distributed section, with taxa occurring in both the south west and east coastal distributions of the genus.
The Dryomyzidae are a small family of flies ranging from 4–18 mm long, with prominent bristles, and yellow to brown or rust-yellow coloring. The wings are very large. The subcosta is complete and well separated from vein 1. Larvae feed on decaying organic matter - carrion, dung, and fungi. The prelambrum protrudes from the oral cavity. Vibrissae are absent and the postvertical bristles are divergent.
Banksia ser. Crocinae is a taxonomic series in the genus Banksia. The series was first published by Alex George in 1981, but discarded by Kevin Thiele and Pauline Ladiges in 1996, and finally reinstated by George in 1999. Recent cladistic analyses suggest that it is monophyletic or nearly so.
George Bentham's taxonomic arrangement of Banksia was published in 1870, in Volume 5 of Bentham's Flora Australiensis. A substantial improvement on the previous arrangement, it would stand for over a century. It was eventually replaced by Alex George's 1981 arrangement, published in his classic monograph The genus Banksia L.f. (Proteaceae).
Eustigmatophytes are a small group of eukaryotic algae that includes marine, freshwater and soil-living species.
Banksia subser. Banksia is a valid botanic name for a subseries of Banksia. It was first used by Kevin Thiele in 1996, although as an autonym it is not considered to have been published per se. It was discarded by Alex George in 1999.
The Petralona cave also Cave of the Red Stones, a karst formation, is located at 300 m (984 ft) above sea-level on the western foot of Mount Katsika, about 1 km (0.62 mi) east of the village of Petralona, about 35 km (22 mi) south-east of Thessaloniki city on the Chalkidiki peninsula, Greece. The site came to public attention when in 1960 a fossilized archaic human skull was found. The cave had been discovered accidentally only a year earlier (1959) after erosion had left clefts in the rock. "Bejeweled" with impressive stalactite and stalagmite formations and holding an abundance of fossils, the cave soon attracted geologists and paleontologists. After decades of excavations the cave is open to the public and scientific work is documented and presented in an adjacent archaeological museum.
At certain periods the Soviet state had to deal with large numbers of orphans in the Soviet Union - due to a number of turmoils in the history of the country from its very beginnings. Major contributors to the population of orphans and otherwise homeless children included World War I (1914-1918), the October Revolution of November 1917 followed by the Russian Civil War (1917-1922), famines of 1921–1922 and of 1932–1933, political repression, forced migrations, and the Soviet-German War theatre (1941-1945) of World War II.
