I am responsible for maintaining a breeding colony of tiger salamanders which supplies all lab members with specimens for their varied research projects. I have been with the Collins lab for 24 years and built the colony from a handful of animals to its current size of several hundred animals with two breeding seasons, one in April and the other, offset six months from the natural season, in October. Each season produces as many as 6000 larvae, which can then be used for research at any stage of development. Genealogies are kept on all individuals in the colony. Two important benefits of the colony are that it eases demand on the wild populations and supplies animals year round. One specimen, fondly known as Big Bertha, has been with us since 1983.
