What is Environmentally induced variation in size, energy reserves and hydration of hatchling Painted Turtles, Chrysemys picta about?
## Summary The contents of newly constructed nests of Painted Turtles, __Chrysemys picta__ (Schneider 1783), were manipulated by reciprocal transplant so that each of several nests received a complement of eggs from each of several females. The eggs were recovered from nests after 8 weeks and allowed to complete their incubation under standard conditions in the laboratory. The design of the experiment enabled us to distinguish between environmental and maternal effects on attributes of hatchlings. Several measures of body size and energy reserve varied among turtles hatching from eggs that incubated in different nests, and certain of these measures varied also among turtles hatching from eggs that incubated in different layers within nests. The effects of nest and layer were substantial. For example, fat‐free carcasses of hatchlings from one nest weighed 17% more than those of neonates from a second nest, but fat‐free yolks from the former weighed only 53% as much as yolks from the latter. Stepwise linear regression indicated that the size of hatchlings and the hydration and fat content of their carcasses were positively correlated with the net change in mass of eggs (which is an i
