Nicrophorus Humator
''Nicrophorus humator'' is a burying beetle described by Gleditsch in 1767 (as ''Silpha humator''). It has a Palearctic distribution, including North Africa. A fossil dating to around 10,500 years ago was described in 1962 by Pearson Pearson may refer to: Organizations Education *Lester B.

Johann Gottlieb Gleditsch
Johann Gottlieb Gleditsch (5 February 1714, in Leipzig – 5 October 1786, in Berlin) was a German physician and botanist known for pioneer investigations of plant sexuality and reproduction. Biography He studied medicine and other subjects at the University of Leipzig (1728–35), where one of his instructors was the naturalist Johann Ernst Hebenstreit (1703–1757). From 1742 he gave lectures in physiology, botany and materia medica at the University of Frankfurt, afterwards relocating to Berlin as a professor of botany at the Collegium Medico-chirurgicum and director of the local botanical garden. Beginning in 1770, he gave lectures at the recently established institute of forestry, where he was instrumental in providing a scientific basis for the field of forestry. In his experiments involving plant movement, he demonstrated the influence that climatic factors had upon plant organs. Also, his view on the role that insects play in pollination of plants was considered t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burying Beetle
Burying beetles or sexton beetles, genus ''Nicrophorus'', are the best-known members of the family Silphidae (carrion beetles). Most of these beetles are black with red markings on the elytra (forewings). Burying beetles are true to their name—they bury the carcasses of small vertebrates such as birds and rodents as a food source for their larvae. They are unusual among insects in that both the male and female parents take care of the brood. They are carnivores. The genus name is sometimes spelled ''Necrophorus'' in older texts: this was an unjustified emendation by Carl Peter Thunberg (1789) of Fabricius's original name, and is not valid under the ICZN. The American burying beetle (''Nicrophorus americanus'') has been on the U.S. endangered species list since 1989. Reproduction Burying beetles have large club-like antennae equipped with chemoreceptors capable of detecting a dead animal from a long distance. After finding a carcass (most usually that of a small bird or a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palearctic
The Palearctic or Palaearctic is the largest of the eight biogeographic realms of the Earth. It stretches across all of Eurasia north of the foothills of the Himalayas, and North Africa. The realm consists of several bioregions: the Euro-Siberian region; the Mediterranean Basin; the Sahara and Arabian Deserts; and Western, Central and East Asia. The Palaearctic realm also has numerous rivers and lakes, forming several freshwater ecoregions. The term 'Palearctic' was first used in the 19th century, and is still in use as the basis for zoogeographic classification. History In an 1858 paper for the ''Proceedings of the Linnean Society'', British zoologist Philip Sclater first identified six terrestrial zoogeographic realms of the world: Palaearctic, Aethiopian/Afrotropic, Indian/Indomalayan, Australasian, Nearctic, and Neotropical. The six indicated general groupings of fauna, based on shared biogeography and large-scale geographic barriers to migration. Alfred Wallace a ...

Oliver Paynie Pearson
Oliver Payne Pearson (October 21, 1915 in Philadelphia, Pennsylvania – March 4, 2003 in Walnut Creek, California), or "Paynie" to many that knew him, was an American zoologist and ecologist. Over a very active 50-year career, he served as professor of zoology at UC Berkeley and curator of mammals at the Museum of Vertebrate Zoology. Pearson is best known for his work on the role of predation on vole demography and population cycles, and for his piercing contributions to the biology of South American mammals, but his earlier studies on reproductive and physiological ecology are highly regarded as well. Background Pearson graduated from Swarthmore College in 1937. He attended Harvard University for both his M.S. (1939) and Ph.D. (1947), and was then hired by UC Berkeley as an instructor in zoology (1947–48). He was an assistant professor of zoology (Department of Zoology) and assistant curator of mammals (Museum of Vertebrate Zoology, MVZ) from 1949 to 1955, gaining tenure ...

Silphidae
Silphidae is a family of beetles that are known commonly as large carrion beetles, carrion beetles or burying beetles. There are two subfamilies: Silphinae and Nicrophorinae. Nicrophorines are sometimes known as sexton beetles. The number of species is relatively small at around two hundred. They are more diverse in the temperate region although a few tropical endemics are known. Both subfamilies feed on decaying organic matter such as dead animals. The subfamilies differ in which uses parental care and which types of carcasses they prefer. Silphidae are considered to be of importance to forensic entomologists because when they are found on a decaying body they are used to help estimate a post-mortem interval. Taxonomy, evolution, and etymology The family Silphidae belongs to the order Coleoptera. They are commonly referred to as carrion beetles or burying beetles and are usually associated with carrion, fungi, and dung. In the past, members of the family Agyrtidae were include ...

Beetles Of Asia
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard exos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
