Francis Walker (entomologist)
Francis Walker (31 July 1809 – 5 October 1874) was an English entomologist. He was born in Southgate, London, on 31 July 1809 and died at Wanstead, England on 5 October 1874. He was one of the most prolific authors in entomology, and stirred controversy during his later life as his publications resulted in a huge number of junior synonyms. However, his assiduous work on the collections of the British Museum had great significance. Between June 1848 and late 1873 Walker was contracted by John Edward Gray Director of the Natural History Museum, London, British Museum to catalogue their insects (except Coleoptera) that is Orthoptera, Neuroptera, Hemiptera, Diptera, Lepidoptera and Hymenoptera. Walker largely accomplished this and (Edwards, 1870) wrote of the plan and by implication those who implemented it: It is to him [Gray] that the Public owe the admirable helps to the study of natural history which have been afforded by the series of inventories, guides, and nomenclatures, ...

Courtship Feeding
Formally, a nuptial gift is a material presentation to a recipient by a donor during or in relation to sexual intercourse that is not simply gametes in order to improve the reproductive fitness of the donor. Often, such a gift will improve the fitness of the recipient as well. This definition implies neutral gifts, costly gifts and beneficial gifts regarding the fitness of the recipient. Nuptial gifting is at the intersection of sexual selection, nutritional ecology, and life history theory, creating a link between the three. Edible and inedible nuptial gifts Many nuptial gifts are a source of nutrition for the recipient. In many species of animals, including birds, insects, and spiders, this takes the form of a food item that is transferred from a male to a female just prior to copulation. This is a behavior known as courtship feeding. Inedible tokens may include items such as a fragment of leaf or twig, a seed tuft, or a silk balloon. How gifts are received There are three ...

Fecundity
Fecundity is defined in two ways; in human demography, it is the potential for reproduction of a recorded population as opposed to a sole organism, while in population biology, it is considered similar to fertility, the capability to produce offspring, measured by the number of gametes (eggs), seed set, or asexual propagules. Human demography Human demography considers only human fecundity, at its culturally differing rates, while population biology studies all organisms. The term ''fecundity'' in population biology is often used to describe the rate of offspring production after one time step (often annual). In this sense, fecundity may include both birth rates and survival of young to that time step. While levels of fecundity vary geographically, it is generally a consistent feature of each culture. ''Fecundation'' is another term for fertilization. In obstetrics and gynecology, fecund-ability is the probability of being pregnant in a single menstrual cycle, and ...

Selection (biology)
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the Heredity, heritable traits characteristic of a population over generations. Charles Darwin popularised the term "natural selection", contrasting it with selective breeding, artificial selection, which is intentional, whereas natural selection is not. Genetic diversity, Variation of traits, both Genotype, genotypic and phenotypic, exists within all populations of organisms. However, some traits are more likely to facilitate survival and reproductive success. Thus, these traits are passed the next generation. These traits can also become more Allele frequency, common within a population if the environment that favours these traits remains fixed. If new traits become more favoured due to changes in a specific Ecological niche, niche, microevolution occurs. If new traits become more favoured due to changes in the ...

Annual Review Of Entomology
The ''Annual Review of Entomology'' is a peer-reviewed academic journal that publishes review articles about entomology, the study of insects. First published in 1956 from a collaboration between the Entomological Society of America and Annual Reviews (publisher), Annual Reviews, its longest-serving editors are Thomas E. Mittler (1967–1997) and May Berenbaum (1998–2018). ''Annual Review of Entomology'' is being published as open access, under the Subscribe to Open model. Also ''Journal Citation Reports'' gives the journal a 2023 impact factor of 15.0, ranking it first of 109 journals in the category "Entomology". History In 1953, a committee within the Entomological Society of America examined the volume of literature published each year in the field and recommended that a journal be established that published review articles. The Entomological Society approached the nonprofit publisher Annual Reviews (publisher), Annual Reviews, which also agreed that there was a need fo ...

Cornell University Press
The Cornell University Press is the university press of Cornell University, an Ivy League university in Ithaca, New York. It is currently housed in Sage House, the former residence of Henry William Sage. It was first established in 1869, making it the first university publishing enterprise in the United States, but was inactive from 1884 to 1930. The press was established in the College of the Mechanic Arts, as mechanical engineering was called in the 19th century, because engineers knew more about running steam-powered printing presses than literature professors. Since its inception, The press has offered work-study financial aid: students with previous training in the printing trades were paid for typesetting and running the presses that printed textbooks, pamphlets, a weekly student journal, and official university publications. Today, the press is one of the country's largest university presses. It produces approximately 150 nonfiction titles each year in various disci ...

Orthopterists' Society
The Orthopterists' Society (formerly the Pan American Acridological Society) is an international scientific organization devoted to facilitating communication and research among persons interested in Orthoptera and related organisms. (The Orthoptera include grasshoppers, locusts, crickets, katydids and other insects.) The Society currently has 330 members from 43 countries on six continents. The journal publishes papers on all aspects of the biology of these insects from ecology and taxonomy to physiology, endocrinology, cytogenetics, and control measures. The Society publishes the refereed biannual ''Journal of Orthoptera Research''. The Society was founded in 1976 by some 35 orthopterists who met at San Martín de los Andes, Argentina. Its Constitution and Bylaws were adopted in 1977, and it was accorded tax-exempt status by the United States government in 1978. The meetings held since San Martín have been at Bozeman (US), Maracay, (Venezuela), Saskatoon (Canada), Valsaín (Sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orthoptera Of North America
Orthoptera () is an order of insects that comprises the grasshoppers, locusts, and crickets, including closely related insects, such as the bush crickets or katydids and wētā. The order is subdivided into two suborders: Caelifera – grasshoppers, locusts, and close relatives; and Ensifera – crickets and close relatives. More than 20,000 species are distributed worldwide. The insects in the order have incomplete metamorphosis, and produce sound (known as a "stridulation") by rubbing their wings against each other or their legs, the wings or legs containing rows of corrugated bumps. The tympanum, or ear, is located in the front tibia in crickets, mole crickets, and bush crickets or katydids, and on the first abdominal segment in the grasshoppers and locusts. These organisms use vibrations to locate other individuals. Grasshoppers and other orthopterans are able to fold their wings (i.e. they are members of Neoptera). Etymology The name is derived from the Greek meaning " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insects Described In 1869
Insects (from Latin ') are Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (Insect morphology#Head, head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes, and a pair of antenna (biology), antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a insect brain, brain and a ventral nerve cord. Most insects reproduce Oviparous, by laying eggs. Insects Respiratory system of insects, breathe air through a system of Spiracle (arthropods), paired openings along their sides, connected to Trachea#Invertebrates, small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in ves ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
