"A Field Study of the Kansas Ant-Eating Frog, Gastrophryne olivacea" by Henry S. Fitch is a scientific publication written in the mid-20th century, specifically published in 1956. This comprehensive study focuses on the ecology, behavior, and life history of the Kansas ant-eating frog, a small and abundant amphibian species residing primarily in northeastern Kansas. It offers insights into the frog’s habitat preferences, breeding patterns, and adaptations while elaborating on the impact of environmental factors on its populations. The book details Fitch's extensive field research conducted over six years, from 1949 to 1954, examining various aspects of the ant-eating frog's life. It discusses the frog's secretive behavior, the significance of rainfall in initiating breeding activities, and its unique adaptations for survival in diverse habitats. The research reveals that heavy precipitation encourages mass migrations to breeding ponds, where males call and pair with females for spawning. The study also provides valuable findings on the frog's temperature tolerance, growth rates, and food habits, primarily comprising ants. Overall, this publication serves as a vital contribution to the understanding of amphibian ecology and the specific dynamics of the Kansas ant-eating frog.
