The Phenotron

Many of our experiments are conducted in the "semi-natural" environment we call "The Barn". Allowing mice to live in natural, competitive conditions should give us a more realistic estimate of the effects of our experimental parameters on fitness.

The barn contains six pens, each subdivided into "territories" with hardware cloth. Additional coils of hardware cloth add spatial complexity. Numerous food, water and nest sites are provided.
Daily observations are made in order to gain information about behavior. Individual mice are monitored by reading "earpunches" - small holes we punch in mouse ears that code for id numbers.
