Jacques Daget

from Wikipedia, the free encyclopedia

Jacques Marie Albert Daget (born June 30, 1919 in Vineuil , Loir-et-Cher department , † June 29, 2009 ) was a French ichthyologist .

Life

Daget was the son of Charles Daget and Élisabeth Blanvillain. His father was a landlord. From 1929 to 1935 he completed his secondary studies at the Lycée privé Notre-Dame-des-Aydes in Blois and after preparation at the College Stanislas in Paris, he enrolled in 1938 in the École polytechnique one, but had at the outbreak of World War II his studies interrupt. From 1939 to 1940 he graduated from the École de l'air as a lieutenant . In 1941 he obtained an engineering degree from the École polytechnique and between 1941 and 1943 various certificates and scientific degrees. From then on, Daget devoted himself to biological research and came on a scholarship to the zoological laboratory for reptiles and fish in the Muséum national d'histoire naturelle , which was headed by Léon Benin . From 1946 to 1947 he received a scholarship from the École française d'Afrique in Sudan, where he received a diploma in comparative anatomy . In 1948, as a research intern at the Center national de la recherche scientifique , Daget carried out a paleontological expedition in Greenland . In 1949 he acquired a Sudanese language diploma from the École des langues orientales and was awarded a doctorate in natural sciences . In 1949 he became head of the hydrobiology laboratory at the French Institute for Black Africa in Diafarabé . In 1959 he became research director and in 1967 general inspector at ORSTOM (today Institut de recherche pour le développement , IRD).

In 1965 Daget returned to France, where he became professor in the laboratory for aquatic population dynamics at the Muséum national d'histoire naturelle in 1975 . In 1976 the name of the laboratory was changed to General and Applied Ichthyology and in 1985 Daget took early retirement.

Daget had two main areas of research, ichthyology and the application of mathematics to biology . The study of the fish from Niger or West Africa , which he considered from a systematic, anatomical and biogeographical point of view, led to his interest in the pike fish (Polypteridae), of which he described many new species. In the second phase of his career, Daget developed digital taxonomy, population dynamics and mathematical ecology. He was the first to apply numerical taxonomy to ichthyology and use multidimensional analytical methods to solve aquatic or terrestrial ecological problems. He also carried out various studies on African freshwater mussels , in particular on the Mutelidae family , and dealt with ethnographic aspects such as fishing in the central Niger Delta .

Daget's writings include Révision des affinités phylogénétiques des Polyptéridés (1950), L'Empire peul du Macina (1818–1853) (3rd edition, 1962, in collaboration with Amadou Ampate Bâ), Les Poissons du Niger supérieur (2nd edition, 1968), Les Modèles mathématiques en écologie (2nd edition, 1976), Histoires naturelles franco-portugaises du XIXème siècle (1989, in collaboration with Luis Saldauha) and Catalog raisonné des Mollusques bivalves d'eau douce africains (1998).

In 1971 Daget married Yvonne Kerguenne. This marriage remained childless.
