Leaf Litter Sieve
A leaf litter sieve is a piece of equipment used by entomologists, in particular by coleopterists (beetle collectors) (Cooter 1991, page 7) as an aid to finding invertebrates in leaf litter. A typical leaf litter sieve consists of a gauze with holes of approximately 5 to 10 mm width. The entomologist places handfuls of leaf litter into the sieve, which is placed above a white sheet or tray. The sieve is shaken, and insects are separated from the leaf litter and fall out for inspection. Charles Valentine Riley Charles Valentine Riley (18 September 1843 – 14 September 1895) was a British-born American entomologist and artist. He was one of the first individuals to use biological pest control and authored over 2,400 publications. He convinced Congress ... details use of a simple sieve with a cloth bag.

Entomologist
Entomology () is the scientific study of insects, a branch of zoology. In the past the term "insect" was less specific, and historically the definition of entomology would also include the study of animals in other arthropod groups, such as arachnids, myriapods, and crustaceans. This wider meaning may still be encountered in informal use. Like several of the other fields that are categorized within zoology, entomology is a taxon-based category; any form of scientific study in which there is a focus on insect-related inquiries is, by definition, entomology. Entomology therefore overlaps with a cross-section of topics as diverse as molecular genetics, behavior, neuroscience, biomechanics, biochemistry, systematics, physiology, developmental biology, ecology, morphology, and paleontology. Over 1.3 million insect species have been described, more than two-thirds of all known species. Some insect species date back to around 400 million years ago. They have many kinds of intera ...

Coleopterist
Coleopterology (from Coleoptera and Greek , ''-logia'') is the scientific study of beetles, a branch of entomology. Practitioners are termed coleopterists and form groups of amateurs and professionals for business and pleasure. Among these is The Coleopterists Society, an international organization based in the United States. Journals Research in this field is often published in peer-reviewed journals specific to the field of coleopterology, though journals dealing with general entomology also publish many papers on various aspects of beetle biology. Some of the journals specific to beetle research are: * '' The Coleopterist'' (United Kingdom beetle fauna) * ''The Coleopterists Bulletin'' (published by The Coleopterists Society) * ''Elytron An elytron (; ; , ) is a modified, hardened forewing of beetles (Coleoptera), though a few of the true bugs (Hemiptera) such as the family Schizopteridae are extremely similar; in true bugs, the forewings are called hemelytra (sometim ...

Leaf Litter
Plant litter (also leaf litter, tree litter, soil litter, litterfall or duff) is dead plant material (such as leaves, bark, needles, twigs, and cladodes) that have fallen to the ground. This detritus or dead organic material and its constituent nutrients are added to the top layer of soil, commonly known as the litter layer or O horizon ("O" for "organic"). Litter is an important factor in ecosystem dynamics, as it is indicative of ecological productivity and may be useful in predicting regional nutrient cycling and soil fertility. Characteristics and variability Litterfall is characterized as fresh, undecomposed, and easily recognizable (by species and type) plant debris. This can be anything from leaves, cones, needles, twigs, bark, seeds/nuts, logs, or reproductive organs (e.g. the stamen of flowering plants). Items larger than 2 cm diameter are referred to as coarse litter, while anything smaller is referred to as fine litter or litter. The type of litterfall is ...

Gauze
Gauze is a thin, translucent fabric with a loose open weave. In technical terms "gauze" is a weave structure in which the weft yarns are arranged in pairs and are crossed before and after each warp yarn keeping the weft firmly in place. This weave structure is used to add stability to fabric, which is important when using fine yarns loosely spaced. However, this weave structure can be used with any weight of yarn, and can be seen in some rustic textiles made from coarse hand-spun plant fiber yarns. Gauze is widely used for medical dressings. Gauze can also be made of non-woven fabric. Etymology and history Gauze was traditionally woven in the Gaza region. The English word is said to derive from the place name for Gaza Webster's, 1913 ( ar, غزة ), a center of weaving in the region. Despite a prohibition on trade with non-Christians from religious authorities in medieval Europe, a fine type of silk known as ''gazzatum'' was imported from Gaza as early as the 13th cent ...

Charles Valentine Riley
Charles Valentine Riley (18 September 1843 – 14 September 1895) was a British-born American entomologist and artist. He was one of the first individuals to use biological pest control and authored over 2,400 publications. He convinced Congress to create the United States Entomological Commission and was among the founders of the American Association of Economic Entomologists. Early life The son of a Church of England minister, Charles Valentine Riley was born on 19 September 1843 in London's Chelsea district. When he was around eleven his parents, the Rev. Charles and Mary (née Valentine) Riley, chose to further his education in Europe. There he excelled at art and natural history attending private schools in Dieppe, France and later Bonn, Germany. After the death of his father he was brought home to Britain to enroll in a public school there. Sometime later his mother remarried which may have played a part in his decision, taken at the age of seventeen, to cross the Atlant ...

Tullgren Funnel
A Berlese funnel, also known as Tullgren funnel, Berlese trap, or Berlese-Tullgren funnel, is an apparatus used to extract living organisms, particularly arthropods, from samples of soil. The Tullgren funnel works by creating a desiccation gradient over the sample such that mobile organisms will move away from the dry environment and fall into a collecting vessel, where they perish and are preserved for examination. The illustration shows how it works: a funnel (E) contains the soil or litter (D), and a heat source (F) such as an electric lamp (G) heats the litter. Animals escaping from the desiccation of the litter descend through a filter (C) into a preservative liquid (A) in a receptacle (B). This illustration is merely a schematic, since usually the soil sample will not be crumbled and poured into the funnel (this would inevitably lead to a high amount of soil particles in the preservation fluid requiring laborious work to sort out the soil organisms). In fact, the soil sampl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Amateur Entomologists' Society
The Amateur Entomologists' Society (AES) is a UK organisation for people interested in insects. History Based in the UK, the Amateur Entomologists' Society was founded in 1935 as The Entomological Exchange and Correspondence Club, for the purpose of providing a forum through which amateur and young entomologists could exchange not only information, but also equipment and other such items. 1937 saw the name of the group changed to the Amateur Entomologists Society, which has remained unchanged since then. The journal of the AES first appeared as The Bulletin in 1939, and it was also during this year that the first non-periodical publication, a leaflet entitled "Coleoptera Collecting", was produced. The Society has advised on invertebrate conservation issues for over 40 years, and has been consulted over legislation such as the UK's Wildlife and Countryside Act 1981, and reviews of the Act. In 1989 the Bulletin became a bi-monthly journal instead of quarterly, and now has a co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
