Frisch JD, Geluso K, and Springer JT. (2015) Distributional expansion of the Hispid Cotton Rat (Sigmodon hispidus) into Dawson County, Nebraska. Transactions of the Nebraska Academy of Sciences. Volume 35, 12–14.
In the last century, the Hispid Cotton Rat (Sigmodon hispidus) has moved northward in central parts of the United States, reaching Nebraska in the late 1950s. Recent surveys demonstrate Hispid Cotton Rats inhabit counties across southern parts of Nebraska south of the Platte River. Herein, we report on captures of S. hispidus from a new county (Dawson County), its seasonal occurrence at our study site, and the first known record of the Hispid Cotton Rat north of channels of the Platte River. Our captures represent one of the northern-most records in Nebraska.
