About Us :
Message from the Director:
Our protocols for capture, care, and captive breeding of 13-lined ground squirrels (Spermophilus tridecemlineatus) were published in April 2006, click here for a pdf of the galley proof. The WiSys Technology Foundation, Inc. has filed a patent on our behalf. Any questions regarding licensing should be directed to Dr. Maliyakal John.
Our animals are reared in typical rodent caging at about 68°F in a photoperiod that matches ambient at our Northeastern Wisconsin location. Handled from birth, they are far calmer than wild-caught animals and may present fewer complications from stress. Date of birth, sex, parentage, and health history are all known. Approvals for transfer to other scientists are all in place from the USDA, State DNR, and IACUC.
NOTE for vision researchers: Jacobs & Neitz (Exp Brain Res, vol. 55, 1984) report that the visual system of a congener, Spermophilus beecheyi, is functionally mature at 80 days of age.
With limited resources in 2006, we produced 97 captive-bred offspring from 12 captive-bred breeding pairs and were sold out by August of that year.
We hope to double the number of breeding pairs for 2007. Our chief limitations to yearly production are the number of cages we own, plus the size of our hibernaculum for holding those cages. We are seeking extramural funds to remove these limitations.
If you might be interested in squirrels for 2007, do let us know (age, sex, number, hibernation status, time of year).
If you prefer wild-caught, unconditioned 13-liners, check out the TLS Research web site at http://mywebpages.comcast.net/seg50/tls.html
We also may be able to provide dissected tissues (frozen or fixed) from animals at different stages of hibernation. Where feasible, we will "stretch" animals to meet the needs of as many clients as possible. Contact me to discuss these special tissues.
