Siegfried Jost Casper
Siegfried Jost Casper (12 January 1929 – 13 June 2021) was a German biologist whose primary research was in limnology and the plant genus ''Pinguicula'' (the butterworts). Together with Heinz-Dieter Krausch he published a basic reference work on the freshwater flora of central Europe. For many years he studied the East German lake Stechlinsee as well as the river Saale. In 1966 he published a monograph of the genus ''Pinguicula'', a work that is still in use today. He described at least 14 new species, most recently '' Pinguicula lippoldii'' and ''Pinguicula toldensis'' in 2007.Casper, S.J. 2007.

He served as head of the Botanical Garden of the Friedrich Schiller University of Jena and from 1990 until his death was a member of the "Akademie Gemeinnütziger Wissenschaften" in Erfurt Erfur ...

Biologist
A biologist is a scientist who conducts research in biology. Biologists are interested in studying life on Earth, whether it is an individual cell, a multicellular organism, or a community of interacting populations. They usually specialize in a particular branch (e.g., molecular biology, zoology, and evolutionary biology) of biology and have a specific research focus (e.g., studying malaria or cancer). Biologists who are involved in basic research have the aim of advancing knowledge about the natural world. They conduct their research using the scientific method, which is an empirical method for testing hypotheses. Their discoveries may have applications for some specific purpose such as in biotechnology, which has the goal of developing medically useful products for humans. In modern times, most biologists have one or more academic degrees such as a bachelor's degree plus an advanced degree like a master's degree or a doctorate. Like other scientists, biologists can be fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limnology
Limnology ( ; from Greek λίμνη, ''limne'', "lake" and λόγος, ''logos'', "knowledge") is the study of inland aquatic ecosystems. The study of limnology includes aspects of the biological, chemical, physical, and geological characteristics of fresh and saline, natural and man-made bodies of water. This includes the study of lakes, reservoirs, ponds, rivers, springs, streams, wetlands, and groundwater.Wetzel, R.G. 2001. Limnology: Lake and River Ecosystems, 3rd ed. Academic Press () Water systems are often categorized as either running (lotic) or standing (lentic). Limnology includes the study of the drainage basin, movement of water through the basin and biogeochemical changes that occur en route. A more recent sub-discipline of limnology, termed landscape limnology, studies, manages, and seeks to conserve these ecosystems using a landscape perspective, by explicitly examining connections between an aquatic ecosystem and its drainage basin. Recently, the need to underst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pinguicula
''Pinguicula'', commonly known as the butterworts, is a genus of carnivorous flowering plants in the family Lentibulariaceae. They use sticky, glandular leaves to lure, trap, and digest insects in order to supplement the poor mineral nutrition they obtain from the environment. Of the roughly 80 currently known species, 13 are native to Europe, 9 to North America, and some to northern Asia. The largest number of species is in South and Central America. Etymology The name ''Pinguicula'' is derived from a term coined by Conrad Gesner, who in his 1561 work entitled ''Horti Germaniae'' commented on the glistening leaves: ''"propter pinguia et tenera folia…"'' (Latin ''pinguis'', "fat"). The common name "butterwort" reflects this characteristic. Characteristics The majority of ''Pinguicula'' are perennial plants. The only known annuals are ''P. sharpii'', ''P. takakii'', ''P. crenatiloba'', and ''P. pumila''. All species form stemless rosettes. Habitat Butterworts can be ...

Flora
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

Stechlinsee
Lake Stechlin or Großer Stechlinsee is a lake in Landkreis Oberhavel, Brandenburg, Germany. At an elevation of 60 m, its surface area is 4.52 km². The Stechlin cisco, a dwarfed fish, is found only in this lake. Theodor Fontane's last novel, '' Der Stechlin'', was set in its vicinity.
