Birth Name:	Olwen Anne Elisabeth Rasa
Birth Place:	Wales
Death Place:	South Africa
Occupation:	Ethologist
Known For:	Study of social behaviour of dwarf mongoose

Olwen Anne Elisabeth Rasa (1940 – 15 November 2020) was a British ethologist, known for her long-duration study of the social behaviour of the dwarf mongoose in Kenya.^[1] She had studied aggression among coral reef fish under the pioneering ethologist Konrad Lorenz. Her fieldwork in Kenya's Taru Desert led to a book, Mongoose Watch: A Family Observed, and to a popular German television series, Expedition ins Tierreich. She later studied social behaviour in the yellow mongoose and the sub-social tenebrionid beetle Parastizopus armaticeps.

Education

In 1961 Anne Rasa graduated with Bachelor of Science (with honors) from the Royal College of Science, Imperial College, London University. Subsequently, she received a NATO-scholarship to investigate the aggression of fish. In 1965 she graduated with a Master of Science from the University of Hawaiʻi. In 1970 Rasa received her Ph.D. from London University with a Max-Planck-Scholarship on coral reef fish aggression under Konrad Lorenz.^[1]

Scientific work

From 1970, she continued her work at the Max-Planck-Institut für Verhaltenspsychologie in Seewiesen under Konrad Lorenz. During this period she started her studies on mongoose dwarfs, concentrating on social structure, marking behavior and intra-group aggression.^[1]

From 1975, she worked as a scientific assistant at Marburg University, Germany. She focused on ontogeny of behaviour in the dwarf mongoose and was awarded the Habilitation qualification in 1981.^[1]

From 1981, her work at the University of Bayreuth was financed by a Heisenberg-Scholarship to study dwarf mongoose in the Taru Desert, Kenya. She published the results in Mongoose Watch: A Family Observed with a foreword by Konrad Lorenz. He compares the significance of her works with those of Jane Goodall and Dian Fossey.^[2] In 1984 the book with its results was presented by Bernhard Grzimek in the German TV-series Expedition ins Tierreich and was translated into several languages.^[3]

From 1986, Rasa was associate professor at Pretoria University, South Africa, teaching ethology and starting her studies on Yellow mongoose in the Kalahari Desert.^[1]

In 1991, she became associate professor at the University of Bonn, where she taught ethology and continuing her studies on Yellow mongoose and studies on the sub-social tenebrionid beetle Parastizopus armaticeps. Rasa retired from Bonn at the end of 2000.^[1]

Post retirement

Rasa owned the Nature Reserve Kalahari Trails at the southern end of the Kalahari Desert in South Africa, which she bought a few years prior to her retirement. She lived there since December 2000 and offered accommodation and guided walks to everyone interested in the flora and fauna of the Kalahari.

In 2007, OSHANA published the book KALAHARI – Magnificent Desert with pictures and text by Rasa.

In 2011/2012, Rasa worked as a scientific advisor on a film series called Kalahari Trails which was being shot in the Kalahari.

Personal life and death

Rasa had three children and four grandchildren. She died on 15 November 2020.^{[4] [5] [1]}
