摘要：
In Iowa, the northern grasshopper mouse (Onychomys leucogaster) previously was known only from the northwestern part of the state. Herein, we report records of O. leucogaster front the 1970s and 1980s that extend its distribution into west-central and southwestern Iowa. These records may represent dispersal movements into these parts of Iowa by southward movements from populations in northwestern Iowa or they may represent eastward movements of individuals from Nebraska prior to channelization of the Missouri River.
