Otto Koehler
Otto Koehler (20 December 1889 - 7 January 1974) was a German zoologist and pioneer ethologist. He was a founding editor, along with Konrad Lorenz of the ''Zeitschrift für Tierpsychologie'' (Journal of animal psychology) which was later renamed as ''Ethology''. He was among the earliest to explore the numerical abilities of animals, and to use tools like film to study animal behaviour. Otto was born in Insterburg, Prussia, the fifth and the only child to survive of Lutheran pastor Eduard Koehler and his second wife Karoline née Heinrici. His mother died after his birth and his father died four years later leaving him in the care of his uncle Paul Heinrici. He went to the Royal school at Pforta in 1902 and matriculated in 1907 to then study at the University of Freiburg. He studied mathematics and history and attended August Weismann's classes on zoology and evolution. In 1908 he moved to the University of Munich where he studied botany and listened to lectures in physics from Wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethology
Ethology is a branch of zoology that studies the behavior, behaviour of non-human animals. It has its scientific roots in the work of Charles Darwin and of American and German ornithology, ornithologists of the late 19th and early 20th century, including Charles Otis Whitman, Charles O. Whitman, Oskar Heinroth, and Wallace Craig. The modern discipline of ethology is generally considered to have begun during the 1930s with the work of the Dutch biologist Nikolaas Tinbergen and the Austrian biologists Konrad Lorenz and Karl von Frisch, the three winners of the 1973 Nobel Prize in Physiology or Medicine. Ethology combines laboratory and field science, with a strong relation to neuroanatomy, ecology, and evolutionary biology. Etymology The modern term ''ethology'' derives from the Greek language: wikt:ἦθος, ἦθος, ''ethos'' meaning "character" and , ''wikt:-logia, -logia'' meaning "the study of". The term was first popularized by the American entomologist William Mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Daphnia
''Daphnia'' is a genus of small planktonic crustaceans, in length. ''Daphnia'' are members of the Order (biology), order Anomopoda, and are one of the several small aquatic crustaceans commonly called water fleas because their Saltation (gait), saltatory swimming style resembles the movements of fleas. ''Daphnia'' spp. live in various aquatic environments ranging from acidic swamps to Fresh water, freshwater lakes and ponds. The two most commonly found species of ''Daphnia'' are ''Daphnia pulex, D. pulex'' (small and most common) and ''Daphnia magna, D. magna'' (large). They are often associated with a related genus in the order Cladocera: ''Moina'', which is in the Moinidae group instead of the Daphniidae, and is much smaller than ''D. pulex'' (roughly half the maximum length). Appearance and characteristics The body of a ''Daphnia'' species is usually long, and is divided into Segmentation (biology), segments, although this division is not visible. The hea ...

Paramecium
''Paramecium'' ( , , plural "paramecia" only when used as a Common name, vernacular name) is a genus of eukaryotic, unicellular ciliates, widespread in freshwater, brackish, and Ocean, marine environments. Paramecia are often abundant in stagnant basins and ponds. Because some species are readily cultivated and easily induced to sexual conjugation, conjugate and divide, they have been widely used in classrooms and laboratories to study biological processes. ''Paramecium'' species are commonly studied as model organisms of the ciliate group and have been characterized as the "laboratory rat, white rats" of the phylum Ciliophora. Historical background ''Paramecium'' were among the first ciliates to be observed by microscopy, microscopists, in the late 17th century. They were most likely known to the Dutch pioneer of protozoology, Antonie van Leeuwenhoek, and were clearly described by his contemporary Christiaan Huygens in a letter from 1678. The earliest known illustration of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Karl Von Frisch
Karl Ritter von Frisch, (20 November 1886 – 12 June 1982) was a German-Austrian ethology, ethologist who received the Nobel Prize in Physiology or Medicine in 1973, along with Nikolaas Tinbergen and Konrad Lorenz. His work centered on investigations of the sensory perceptions of the honey bee and he was one of the first to translate the meaning of the waggle dance. His theory, described in his 1927 book ''Aus dem Leben der Bienen'' (translated into English as ''The Dancing Bees''), was disputed by other scientists and greeted with skepticism at the time. Only much later was it shown to be an accurate theoretical analysis. Early life Karl Ritter von Frisch was the son of the surgeon and urologist Anton von Frisch (1849–1917), by his marriage to Marie Exner. Karl was the youngest of four sons, all of whom became university professors. Von Frisch was of partial Jewish heritage. His maternal grandmother was of Jewish origin. Karl studied at the University of Vienna under Hans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard Hertwig
Richard Wilhelm Karl Theodor Ritter von Hertwig (23 September 1850 in Friedberg, Hesse – 3 October 1937 in Schlederloh, Bavaria), also Richard Hertwig or Richard von Hertwig, was a German zoologist and professor of 50 years, notable as the first to describe zygote formation as the fusing of spermatozoa inside the membrane of an egg cell during fertilization. "Richard von Hertwig – Wikipedia" (German), German Wikipedia, 2006-10-29, de.wikipedia.org webpage: GermanWP-Richard_von_Hertwig. Richard Hertwig was the younger brother of Oscar Hertwig, who also analyzed zygote formation. The two Hertwig brothers worked together until 1883 (more at: Oscar Hertwig). The Hertwig brothers were the most eminent scholars of Ernst Haeckel (and Carl Gegenbaur), each brother becoming a long-term professor in Germany. They were independent of Haeckel's philosophical speculations but took his ideas in a positive way to widen their concepts in zoology. Initially, between 1 ...

Konrad Lorenz
Konrad Zacharias Lorenz (Austrian ; 7 November 1903 – 27 February 1989) was an Austrian zoology, zoologist, ethology, ethologist, and ornithologist. He shared the 1973 Nobel Prize in Physiology or Medicine with Nikolaas Tinbergen and Karl von Frisch. He is often regarded as one of the founders of modern ethology, the study of animal behavior. He developed an approach that began with an earlier generation, including his teacher Oskar Heinroth. Lorenz studied instinct, instinctive behavior in animals, especially in Greylag goose, greylag geese and Western jackdaw, jackdaws. Working with geese, he investigated the principle of imprinting (psychology), imprinting, the process by which some nidifugous birds (i.e. birds that leave their nest early) bond instinctively with the first moving object that they see within the first hours of hatching. Although Lorenz did not discover the topic, he became widely known for his descriptions of imprinting as an instinctive bond. In 1936, he m ...
