Abstract

A cotton rat population near Lawrence, Kansas, experienced mortality and changes in density associated with severe weather during March and April 1983. Flooding and low temperatures produced visible evidence of mortality and energystressed animals. These direct observations of cotton rat mortality support the notion that cotton rats in Kansas are particularly susceptible to severe climatic conditions in spring when their energy reserves are minimal.
