Max Beier
Max Beier (6 April 1903 in Spittal an der Drau – 4 July 1979 in Vienna) was an Austrian arachnologist and entomologist. He studied zoology at the University of Vienna, and obtained his doctorate there in 1927. He took up a post at the Natural History Museum in Vienna, in the same year, developing an expertise in pseudoscorpions. He was appointed Director of the zoological department of the Vienna Museum in 1962, and retired in 1968. A list of Beier's 398 scientific papers was published, with an obituary, in ''Annalen des Naturhistorischen Museums in Wien''. 252 were on pseudoscorpions. He described and named over 1200 pseudoscorpion species of which 1180 were still valid in 2007. He was editor of the ''Orthopterorum Catalogus'' and an updated edition of the volume on insects in the '. Awards Beier was awarded the Fabricius Medal in January 1967 of Deutsche Gesellschaft für Allgemeine und Angewandte Entomologie (German entomology society). In July 1968 he was granted an ...

Pseudoscorpion
Pseudoscorpions, also known as false scorpions or book scorpions, are small, scorpion-like arachnids belonging to the order Pseudoscorpiones, also known as Pseudoscorpionida or Chelonethida. Pseudoscorpions are generally beneficial to humans since they prey on clothes moth larvae, carpet beetle larvae, booklice, ants, mites, and small flies. They are tiny, and are rarely noticed due to their small size, despite being common in many environments. When people do see pseudoscorpions, especially indoors, they are often mistaken for ticks or small spiders. Pseudoscorpions often carry out phoresis, a form of commensalism in which one organism uses another for the purpose of transport. Characteristics Pseudoscorpions belong to the class Arachnida. They are small arachnids with a flat, pear-shaped body, and pincer-like pedipalps that resemble those of scorpions. They usually range from in length.Pennsylvania State University, DepartmentEntomological Notes: Pseudoscorpion Fact Sheet/r ...

Passa Quatro
Passa-Quatro is a municipality in the state of Minas Gerais in Brazil. The population is 16,393 (2020 est.) in an area of 277.22 km2. It is part of the microrregion of São Lourenço. Environment The city was declared a hydro-mineral spa in 1941 due to its various fountains of torio-radioactive waters, which are reputedly sought out for curing liver and kidney problems. The winter is dry and the summer mild with temperatures varying between 16 and 22 degrees Celsius. In winter they can drop to 0 degrees with strong frost. This rural area has views of four of the ten highest peaks in the country. Trout fishing is possible all year. A tourist train service (narrow gauge) was inaugurated in the beginning of 2004 between the cities of Passa Quatro and Manacá. The municipality contains the Passa Quatro National Forest, created in 1968. The forest is controlled by IBAMA and has native forest, exotic species, lakes, and the Iporã waterfall.

Animals Described In 1931
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinoderms an ...
