Brief History of the Breeding Program:
Beginning in 2002, I began experimenting with simple ways to breed 13-lined ground squirrels (Spermophilus tridecemlineatus) in captivity, to provide a reliable supply of specimens for my own vision research program. We began with wild animals caught in Winnebago County, Wisconsin, which we over-wintered in captivity and bred the following spring. Over 3 years, we worked out the bugs to achieve reliable reproduction in captivity. With the 2006 breeding season, we marked our 2nd consecutive generation of captive-bred animals (captive-bred babies from parents who themselves were conceived and born in captivity). We use the Han Rotation to minimize homozygosity.
