Kasakela
The Kasekela chimpanzee community (formerly spelled Kasakela) is a habituated community of wild eastern chimpanzees that lives in Gombe National Park near Lake Tanganyika in Tanzania. The community was the subject of Jane Goodall's pioneering study that began in 1960, and studies have continued ever since, becoming the longest continuous study of any animals in their natural habitat. As a result, the community has been instrumental in the study of chimpanzees and has been popularized in several books and documentaries. The community's popularity was enhanced by Goodall's practice of giving names to the chimpanzees she was observing, in contrast to the typical scientific practice of identifying the subjects by number. Goodall generally used a naming convention in which infants were given names starting with the same letter as their mother, allowing the recognition of matrilineal lines. One of the most important discoveries that was learned by observing the Kasekela chimpanzee comm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gombe Chimpanzee War
The Gombe Chimpanzee War, also known as the Four-Year War, was a violent conflict between two communities of chimpanzees in Gombe Stream National Park in the Kigoma region of Tanzania between 1974 and 1978. The two groups were once unified in the Kasakela community. By 1974, researcher Jane Goodall noticed the community splintering. Over a span of eight months, a large party of chimpanzees separated themselves into the southern area of Kasakela and were renamed the Kahama community. The separatists consisted of six adult males, three adult females and their young. The Kasakela was left with eight adult males, twelve adult females and their young. During the four-year conflict, all males of the Kahama community were killed, effectively disbanding the community. The victorious Kasakela then expanded into further territory but were later repelled by another community of chimpanzees. Background Prior to the four-year war, before it became a national park, Gombe Stream National Par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jane Goodall
Dame Jane Morris Goodall (; born Valerie Jane Morris-Goodall on 3 April 1934), formerly Baroness Jane van Lawick-Goodall, is an English primatologist and anthropologist. Seen as the world's foremost expert on chimpanzees, Goodall is best known for her 60-year study of social and family interactions of wild chimpanzees since she first went to Gombe Stream National Park in Tanzania in 1960, where she witnessed human-like behaviours amongst chimpanzees, including armed conflict. She is the founder of the Jane Goodall Institute and the Roots & Shoots programme, and she has worked extensively on conservation and animal welfare issues. As of 2022, she is on the board of the Nonhuman Rights Project. In April 2002, she was named a UN Messenger of Peace. Goodall is an honorary member of the World Future Council. Early years Valerie Jane Morris-Goodall was born in 1934 in Hampstead, London, to businessman Mortimer Herbert Morris-Goodall (1907–2001) and Margaret Myfanwe Joseph (1906â ...

Habituation
Habituation is a form of non-associative learning in which an innate (non-reinforced) response to a stimulus decreases after repeated or prolonged presentations of that stimulus. Responses that habituate include those that involve the intact organism (e.g., full-body startle response) or those that involve only components of the organism (e.g., habituation of neurotransmitter release from ''in vitro'' Aplysia sensory neurons). The broad ubiquity of habituation across all biologic phyla has resulted in it being called "the simplest, most universal form of learning...as fundamental a characteristic of life as DNA." Functionally-speaking, by diminishing the response to an inconsequential stimulus, habituation is thought to free-up cognitive resources to other stimuli that are associated with biologically important events (i.e., punishment/reward). For example, organisms may habituate to repeated sudden loud noises when they learn these have no consequences. A progressive decline of a ...

Hugo Van Lawick
Hugo Arndt Rodolf, Baron van Lawick (10 April 1937 – 2 June 2002) was a Dutch wildlife filmmaker and photographer. Through his still photographs and films, Van Lawick helped popularize the study of chimpanzees during his wife Jane Goodall's studies at Gombe Stream National Park during the 1960s and 1970s. His films drew the attention of the viewing public to the dramatic life cycles of several wild animals of the Serengeti, such as wild dogs, elephants, and lions. Early life He was born in Surabaya, Dutch East Indies (now Indonesia) as the son of Baron Hugo Anne Victor Raoul van Lawick (11 August 1909 – 17 June 1941) and the former Isabella Sophia van Ittersum (11 February 1913 – 30 December 1977). His father was a pilot with the Dutch fleet, and upon his death while in service the Baroness moved Hugo and his brother first to Australia, then to England, where they lived successively, in London, Hull, and Devon. In the latter, Hugo was enrolled in boarding school, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wean
Weaning is the process of gradually introducing an infant human or another mammal to what will be its adult diet while withdrawing the supply of its mother's milk. The process takes place only in mammals, as only mammals produce milk. The infant is considered to be fully weaned once it is no longer fed by any breast milk (or bottled substitute). Humans In some cultures, weaning progresses with the introduction of feeding the child food that has been prechewed by the parent along with continued breastfeeding, a practice known as premastication. The practice was important throughout human history in that it naturally gave a child a greatly improved protein source in addition to preventing iron deficiency. However, premasticated food from caregivers of lower socioeconomic status in areas of endemic diseases can result in the passing of the disease to the child. How and when to wean a human infant is controversial. The American Academy of Pediatrics recommends feeding a baby onl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Beta (biology)
In biology, a dominance hierarchy (formerly and colloquially called a pecking order) is a type of social hierarchy that arises when members of animal social groups interact, creating a ranking system. A dominant higher-ranking individual is sometimes called an alpha, and the submissive lower-ranking individual a beta. Different types of interactions can result in dominance depending on the species, including ritualized displays of aggression or direct physical violence. In social living groups, members are likely to compete for access to limited resources and mating opportunities. Rather than fighting each time they meet, relative rank is established between individuals of the same sex, with higher-ranking individuals often gaining more access to resources and mates. Based on repetitive interactions, a social order is created that is subject to change each time a dominant animal is challenged by a subordinate one. Definitions Dominance is an individual's preferential acces ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sarcoptic Mange
Mange is a type of skin disease caused by parasitic mites. Because various species of mites also infect plants, birds and reptiles, the term "mange", or colloquially "the mange", suggesting poor condition of the skin and fur due to the infection, is sometimes reserved for pathological mite-infestation of nonhuman mammals. Thus, mange includes mite-associated skin disease in domestic mammals (cats and dogs), in livestock (such as sheep scab), and in wild mammals (for example, foxes, coyotes, cougars, and bears). Since mites belong to the arachnid subclass Acari (also called Acarina), another term for mite infestation is acariasis. Parasitic mites that cause mange in mammals embed themselves in either skin or hair follicles in the animal, depending upon their genus. ''Sarcoptes'' spp. burrow into skin, while ''Demodex'' spp. live in follicles. In humans, these two types of mite infections, which would be known as "mange" in furry mammals, are instead known respectively as scabies ...

Molecular Ecology
Molecular ecology is a field of evolutionary biology that is concerned with applying molecular population genetics, molecular phylogenetics, and more recently genomics to traditional ecological questions (e.g., species diagnosis, conservation and assessment of biodiversity, species-area relationships, and many questions in behavioral ecology). It is virtually synonymous with the field of "Ecological Genetics" as pioneered by Theodosius Dobzhansky, E. B. Ford, Godfrey M. Hewitt, and others. These fields are united in their attempt to study genetic-based questions "out in the field" as opposed to the laboratory. Molecular ecology is related to the field of conservation genetics. Methods frequently include using microsatellites to determine gene flow and hybridization between populations. The development of molecular ecology is also closely related to the use of DNA microarrays, which allows for the simultaneous analysis of the expression of thousands of different genes. Quanti ...

Bipedal
Bipedalism is a form of terrestrial locomotion where an organism moves by means of its two rear limbs or legs. An animal or machine that usually moves in a bipedal manner is known as a biped , meaning 'two feet' (from Latin ''bis'' 'double' and ''pes'' 'foot'). Types of bipedal movement include walking, running, and hopping. Several groups of modern species are habitual bipeds whose normal method of locomotion is two-legged. In the Triassic period some groups of archosaurs (a group that includes crocodiles and dinosaurs) developed bipedalism; among the dinosaurs, all the early forms and many later groups were habitual or exclusive bipeds; the birds are members of a clade of exclusively bipedal dinosaurs, the theropods. Within mammals, habitual bipedalism has evolved multiple times, with the macropods, kangaroo rats and mice, springhare, hopping mice, pangolins and hominin apes ( australopithecines, including humans) as well as various other extinct groups evolving the ...
