Abstract
The importance of genetic and environmental variation in condition in
shaping evolutionary trade-offs have recently been subject to much theoretical
discussion, but is very difficult to investigate empirically in most field-based
systems. We present the results from mechanistic experimental manipulations
of reproductive investment and condition in two female colour morphs
(`orange' and `yellow') of side-blotched lizards (Uta stansburiana). We
