John Marshall Legler

from Wikipedia, the free encyclopedia

John Marshall Legler (born September 9, 1930 in Minneapolis , Minnesota , † March 28, 2014 in Salt Lake City , Utah ) was an American herpetologist . His research focus was the turtles .

Life

From 1952 to 1953 Legler was an assistant in human anatomy at Gustavus Adolphus College in St. Peter , Minnesota . In 1953 he obtained a Bachelor of Arts from Gustavus Adolphus College. From 1953 to 1957 he was an assistant in zoology at the University of Kansas . From 1955 to 1959 he was assistant curator in the herpetological department of the University of Kansas Natural History Museum. In 1959 he was an assistant professor of herpetology at the University of Kansas, where he received his Ph.D. received his doctorate. In 1969 he became professor of biology at the University of Utah, where he developed a study program in human anatomy. In 1997 he resigned as a professor emeritus in order to devote himself entirely to research.

Legler is best known for his turtle projects, including his Ph.D. -Study of the American box turtle ( Terrapene ornata ) in Kansas from 1959 and the study of land and freshwater turtles in Mexico and Central America , which resulted in the publication of his major works The life History of the Slider Turtle (1971) and The Turtles of Mexico (2013) culminated. The latter work was created in collaboration with Richard Carl Vogt .

Legler described some new turtle species and subspecies from North and Central America and Australia, including the yellow-tipped gopher tortoise ( Gopherus flavomarginatus ), the Alamos folding turtle ( Kinosternon alamosae ), the Costa Rican folding turtle ( Kinosternon angustipons ), the subspecies Trachemys scriptustipons taylori of the North American ring turtle , the subspecies Apalone spinifera atra of the thorn-edge softshell turtle , the Fitzroy turtle ( Rheodytes leukops ) and the Mary River turtle ( Elusor macrurus ). He also described the blind snake species Typhlops silus .

Legler's most important contributions to species protection were the techniques he developed that prevented the unnecessary slaughter of innumerable turtles in order to preserve stomach contents for nutritional studies and eggs for incubation studies. Together with his son Austin, he developed a technique in Australia to get at the stomach contents of turtles without causing life-threatening damage to the animals. John Legler and Michael A. Ewert published the technique of inducing oviposition in pregnant turtles by injecting oxytocin in 1978 in the journal Herpetologica .

Honors and Dedication Names

In 2010 the Chair of Human Anatomy at the University of Utah was named after John Legler. In 1958 Edward Harrison honored Taylor Legler in the type epithet of the frog species Ptychohyla legleri .
