Ethologist
Ethology is the scientific study of animal behaviour, usually with a focus on behaviour under natural conditions, and viewing behaviour as an evolutionarily adaptive trait. Behaviourism as a term also describes the scientific and objective study of animal behaviour, usually referring to measured responses to stimuli or to trained behavioural responses in a laboratory context, without a particular emphasis on evolutionary adaptivity. Throughout history, different naturalists have studied aspects of animal behaviour. Ethology has its scientific roots in the work of Charles Darwin and of American and German ornithologists of the late 19th and early 20th century, including 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 Dutch biologist Nikolaas Tinbergen and Austrian biologists Konrad Lorenz and Karl von Frisch, the three recipients of the 1973 Nobel Prize in Phys ...

Neuroethology
Neuroethology is the evolutionary and comparative approach to the study of animal behavior and its underlying mechanistic control by the nervous system. It is an interdisciplinary science that combines both neuroscience (study of the nervous system) and ethology (study of animal behavior in natural conditions). A central theme of neuroethology, which differentiates it from other branches of neuroscience, is its focus on behaviors that have been favored by natural selection (e.g., finding mates, navigation, locomotion, and predator avoidance) rather than on behaviors that are specific to a particular disease state or laboratory experiment. Neuroethologists hope to uncover general principles of the nervous system from the study of animals with exaggerated or specialized behaviors. They endeavor to understand how the nervous system translates biologically relevant stimuli into natural behavior. For example, many bats are capable of echolocation which is used for prey capture and navi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Konrad Lorenz
Konrad Zacharias Lorenz (; 7 November 1903 – 27 February 1989) was an Austrian zoologist, 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 instinctive behavior in animals, especially in greylag geese and jackdaws. Working with geese, he investigated the principle of 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 met Tinbergen, and the two collaborated in developing ethology as a separate sub-discipline o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animal Communication
Animal communication is the transfer of information from one or a group of animals (sender or senders) to one or more other animals (receiver or receivers) that affects the current or future behavior of the receivers. Information may be sent intentionally, as in a courtship display, or unintentionally, as in the transfer of scent from predator to prey. Information may be transferred to an "audience" of several receivers. Animal communication is a rapidly growing area of study in disciplines including animal behavior, sociology, neurology and animal cognition. Many aspects of animal behavior, such as symbolic name use, emotional expression, learning and sexual behavior, are being understood in new ways. When the information from the sender changes the behavior of a receiver, the information is referred to as a "signal". Signalling theory predicts that for a signal to be maintained in the population, both the sender and receiver should usually receive some benefit from the interac ...

Karl Von Frisch
Karl Ritter von Frisch, (20 November 1886 – 12 June 1982) was a German-Austrian 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 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. Karl studied in Vienna under Hans Leo Przibram and in Munich under Richard von Hertwig, initially in the field o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animal Aggression
Aggression is overt or covert, often harmful, social interaction with the intention of inflicting damage or other harm upon another individual; although it can be channeled into creative and practical outlets for some. It may occur either reactively or without provocation. In humans, aggression can be caused by various triggers, from frustration due to blocked goals to feeling disrespected. Human aggression can be classified into direct and indirect aggression; whilst the former is characterized by physical or verbal behavior intended to cause harm to someone, the latter is characterized by behavior intended to harm the social relations of an individual or group. In definitions commonly used in the social sciences and behavioral sciences, aggression is an action or response by an individual that delivers something unpleasant to another person. Some definitions include that the individual must intend to harm another person. In an interdisciplinary perspective, aggression is rega ...

Oskar Heinroth
Oskar Heinroth (1 March 1871 – 31 May 1945) was a German biologist who was one of the first to apply the methods of comparative morphology to animal behavior, and was thus one of the founders of ethology. He worked, largely isolated from most other scientists of the period, at the Berlin Aquarium where he took care of fishes, reptiles and birds, especially waterfowl. Biography Heinroth was born in Mainz-Kastel. He studied medicine and graduated in 1895, but later studied zoology at Berlin while working at the Zoological Garden and at the Natural History Museum. He joined an expedition to the Bismarck Archipelago in 1900-1901 serving as a zoologist to Bruno Mencke, the South Seas expedition leader who was attacked and killed in an encounter with indigenous peoples while Heinroth himself escaped with a spear wound. In 1904 Heinroth became an assistant at the Berlin Zoological Garden. He began his studies of duck and goose behavior while working as a scientific assistant fr ...

Wallace Craig
Wallace Craig (1876–1954) was an American experimental psychologist and behavior scientist. He provided a conceptual framework for the study of behavior organization and is regarded as one of the founders of ethology. Craig experimentally studied the behavioral expression of emotion, the way innate and learned behavioral tendencies are integrated, and how vocal as well as social behaviors are organized. He encouraged a view of behavior as an integrated process with evolutionary, motivational, experiential, social and ecological degrees of freedom. This integrative perspective helped shape modern behavioral science. Early life and education Wallace Craig was born on July 20, 1876, in Toronto, Ontario, Canada, the son of Alexander Craig of Edinburgh, a Scottish immigrant to the United States, and Marion Brookes of London, an Englishwoman. He married Mima Davis Jenness of Sheffield on October 12, 1904. Craig graduated from Hyde Park High School, Chicago, Illinois, in 1895 and r ...

Nikolaas Tinbergen
Nikolaas "Niko" Tinbergen (; ; 15 April 1907 – 21 December 1988) was a Dutch biologist and ornithologist who shared the 1973 Nobel Prize in Physiology or Medicine with Karl von Frisch and Konrad Lorenz for their discoveries concerning the organization and elicitation of individual and social behavior patterns in animals. He is regarded as one of the founders of modern ethology, the study of animal behavior. In 1951, he published ''The Study of Instinct'', an influential book on animal behaviour. In the 1960s, he collaborated with filmmaker Hugh Falkus on a series of wildlife films, including ''The Riddle of the Rook'' (1972) and ''Signals for Survival'' (1969), which won the Italia prize in that year and the American blue ribbon in 1971. Education and early life Born in The Hague, Netherlands, he was one of five children of Dirk Cornelis Tinbergen and his wife Jeannette van Eek. His brother, Jan Tinbergen, won the first Bank of Sweden Prize in Economic Sciences in Memory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evolution
Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes, which are passed on from parent to offspring during reproduction. Variation tends to exist within any given population as a result of genetic mutation and recombination. Evolution occurs when evolutionary processes such as natural selection (including sexual selection) and genetic drift act on this variation, resulting in certain characteristics becoming more common or more rare within a population. The evolutionary pressures that determine whether a characteristic is common or rare within a population constantly change, resulting in a change in heritable characteristics arising over successive generations. It is this process of evolution that has given rise to biodiversity at every level of biological organisation, including the levels of species, individual organisms, and molecules. The theory of evolut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ἦθος
Ethos ( or ) is a Greek word meaning "character" that is used to describe the guiding beliefs or ideals that characterize a community, nation, or ideology; and the balance between caution, and passion. The Greeks also used this word to refer to the power of music to influence emotions, behaviors, and even morals. Early Greek stories of Orpheus exhibit this idea in a compelling way. The word's use in rhetoric is closely based on the Greek terminology used by Aristotle in his concept of the three artistic proofs or modes of persuasion. It gives credit to the speaker, or the speaker is taking credit. Etymology and origin ''Ethos'' (, ; ''plurals:'' ''ethe'', ; ''ethea'', ) is a Greek word originally meaning "accustomed place" (as in "the habitats of horses/", ''Iliad'' 6.511, 15.268), "custom, habit", equivalent to Latin ''mores''. ''Ethos'' forms the root of ''ethikos'' (), meaning "morality, showing moral character". As an adjective in the neuter plural form ''ta ethika.'' Cu ...

Greek Language
Greek ( el, label= Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy ( Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works ...
