Oliver Payne Pearson
Oliver Payne Pearson (October 21, 1915, in
Philadelphia, Pennsylvania – March 4, 2003, in
Walnut Creek, California), or "Paynie" to many that knew him, was an American
zoologist and
ecologist. Over a very active 50-year career, he served as professor of zoology at
UC Berkeley and curator of mammals at the
Museum of Vertebrate Zoology. Pearson is best known for his work on the role of predation on
vole demography and population cycles, and for his piercing contributions to the biology of South American mammals, but his earlier studies on reproductive and physiological ecology are highly regarded as well.
