Katherine S. Ralls is an American zoologist and conservationist who is Senior Research Zoologist Emerita at the Smithsonian Conservation Biology Institute, National Zoological Park.[1] Ralls' research interests are in the behavioral ecology, genetics, and conservation of mammals, both terrestrial and marine. Since 1980, she has focused on conservation biology, especially the genetic problems of small captive and wild populations.
Two mammals that she has studied extensively are the sea otter and the San Joaquin kit fox.[2] Some of her research is on the genetic management of wild and captive animal populations.[3]
Ralls worked on the founding of the Society for Conservation Biology in the mid-1980s.[7] In 1986, she and research associate Jonathan Ballou, (now research scientist emeritus at the Smithsonian Conservation Biology Institute),[8] developed an international workshop on genetic management for zoo animals.[3] In 2017, Ralls, Ballou, and Richard Frankham published the first book on the genetic management of fragmented species populations, "Genetic Management of Fragmented Animal and Plant Populations."[9]
