Entomologischer Verein Krefeld
The Entomologischer Verein Krefeld (EVK) is an entomological society based in Krefeld, North Rhine-Westphalia, Germany. Founded in 1905, it keeps meticulous records and specimens of the area's insects, a collection curated since 1987 by entomologist Martin Sorg. The EVK is known in particular for a study it conducted, published in '' PLOS One'' in 2017, that demonstrated a 75 percent decline in flying insect biomass in 63 nature reserves in Germany between 1989 and 2016. The paper became the "third most frequently cited scientific study" of 2017 in the media, according to ''The Economist''. Membership Based in a former school in Krefeld's Marktstraße, the EVK has around 50 members, many of them hobbyists, who, according to Gretchen Vogel in ''Science'', "have become world experts on their favorite insects". One member, Siegfried Cymorek, who did not graduate from high school, was awarded an honorary doctorate in 1979 by the Swiss Federal Institute of Technology in Zurich for his ...

Krefeld
Krefeld ( , ; li, Krieëvel ), also spelled Crefeld until 1925 (though the spelling was still being used in British papers throughout the Second World War), is a city in North Rhine-Westphalia, Germany. It is located northwest of Düsseldorf, its center lying just a few kilometers to the west of the river Rhine; the borough of Uerdingen is situated directly on the Rhine. Because of its economic past, Krefeld is often referred to as the "Velvet and Silk City". It is accessed by the autobahns A57 (Cologne– Nijmegen) and A44 (Aachen–Düsseldorf– Dortmund–Kassel). Krefeld's residents now speak ', or standard German, but the native dialect is a Low Franconian variety, sometimes locally called ', ', ', or sometimes simply '. The Uerdingen line isogloss, separating general dialectical areas in Germany and neighboring Germanic-speaking countries, runs through and is named after Krefeld's Uerdingen district, originally an independent municipality.

Woodboring Beetle
The term woodboring beetle encompasses many species and families of beetles whose larval or adult forms eat and destroy wood (i.e., are xylophagous). In the woodworking industry, larval stages of some are sometimes referred to as woodworms. The three most species-rich families of woodboring beetles are longhorn beetles, bark beetles and weevils, and metallic flat-headed borers. Woodboring is thought to be the ancestral ecology of beetles, and bores made by beetles in fossil wood extend back to the earliest fossil record of beetles in the Early Permian (Asselian), around 295-300 million years ago. Ecology Woodboring beetles most often attack dying or dead trees. In forest settings, they are important in the turnover of trees by culling weak trees, thus allowing new growth to occur. They are also important as primary decomposers of trees within forest systems, allowing for the recycling of nutrients locked away in the relatively decay-resilient woody material of trees. To develop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Annals Of Applied Biology
The Association of Applied Biologists (AAB) is a United Kingdom biological science learned society. From its foundation in 1904 until 1934, the institution was the Association of Economic Biologists. It publishes research and holds conferences in different specialisms of applied biology. History The AAB was founded in 1904 as the ''Association of Economic Biologists'' for workers in applied biology "to discuss new discoveries, to exchange experiences and carefully consider the best methods of work" and "promote and advance the science of Economic Biology in its agricultural, horticultural, medical and commercial aspects."''Association of Applied Biologists 1904–2004: A Celebration of Achievement''. Wellesbourne:Association of Applied Biologists, 2004 "Within 10 years of its foundation, the association became the recognised society for all British workers interested in applied biology. Since then, the association has steadily expanded its knowledge." In 1934, the current title ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Economist
''The Economist'' is a British weekly newspaper printed in demitab format and published digitally. It focuses on current affairs, international business, politics, technology, and culture.

Over time, the newspaper's coverage expanded further into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Decline In Insect Populations
An increasing number of scientific studies are reporting substantial declines in insect populations worldwide. Most commonly, the declines involve reductions in abundance, though in some cases entire species are going extinct. The declines are far from uniform. In some localities, there have been reports of increases in overall insect population, and some types of insects appear to be increasing in abundance across the world. Some of the insects most affected include bees, butterflies, moths, beetles, dragonflies and damselflies. Anecdotal evidence has been offered of much greater apparent abundance of insects in the 20th century; recollections of the windscreen phenomenon are an example. Possible causes are similar to other biodiversity loss, with studies identifying: habitat destruction, including intensive agriculture; the use of pesticides (particularly insecticides); urbanization, and industrialization; introduced species; and climate change. Not all insect orders ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Entomological
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 interacti ...

List Of Nature Parks In Germany
Nature parks in Germany (german: Naturparks) have been established under section 22, paragraph 4 of that country's Federal Nature Conservation Act (BNatSchG). there were 103 nature parks, comprising about 27 percent of the total land area of Germany and are brought together under the Association of German Nature Parks. In total there are 23,159 Protected Areas in Germany. Parks that overlap into neighbouring countries are led by Europarc. The oldest nature park is Lüneburg Heath Nature Park, whose core area was established in 1921 as a nature reserve; by 2007, it had expanded to more than four times its original area. the largest nature reserve in Germany, with , is the Southern Black Forest Nature Park. The surface area of nature parks in Germany increased by 42% between 1998 and the end of 2019 (this corresponds to around 3.0 million hectares).
