Early experien.e can.prepare offsprin. to adapt their behaviors to the en.iron.en. they are likely to en.oun.er later in.life. In.several species of an.s, colon.es show on.ogen.c chan.es in.the brood-to-worker ratio that are kn.wn.to have an.impact on.worker morphology. However, little in.ormation.is available on.the in.luen.e of fluctuation. in.the early social con.ext on.the expression.of behavior in.adulthood. Usin. the an. Lasius n.ger, we tested whether the brood-to-worker ratio durin. larval stages in.luen.ed the level of behavioral variability at adult stages. We raised batches of 20 or 180 larvae in.the presen.e of 60 workers un.il adulthood. We then.quan.ified the activity level an. wall-followin. ten.en.y of callow workers on.10 successive trials to test the prediction.that larvae reared un.er a high brood-to-worker ratio should show greater behavioral variation.. We foun. that man.pulation.of the brood-to-worker ratio in.luen.ed the duration.of developmen. an. the size of in.ividuals at emergen.e. We detected n. in.luen.e of early social con.ext on.the level of between. or within.in.ividual variation.measured for in.ividual activity level or on.wall-followin. behavior. Our study suggests that behavioral traits may be more can.lized than.morphological traits.

We report progress towards a modern.scien.ific description.of thermodyn.mic properties of fluids followin. the discovery (in.2012) of a coexistin. critical den.ity hiatus an. a supercritical mesophase defin.d by percolation.tran.ition.. The state fun.tion. den.ity ρ(p,T), an. Gibbs en.rgy G(p,T), of fluids, e.g. CO2, H2O an. argon.exhibit a symmetry characterised by the rigidity, ω = (dp/dρ)T, between.gaseous an. liquid states alon. an. isotherm from critical (Tc) to Boyle (TB) temperatures, on.either side of the supercritical mesophase. Here, usin. experimen.al data for fluid argon. we in.estigate the low-den.ity cluster physics description.of an.ideal dilute gas that obeys Dalton.s partial pressure law. Cluster expan.ion. in.powers of den.ity relate to a supercritical liquid-phase rigidity symmetry (RS) lin. (ω = ρrs(T) = RT) to gas phase virial coefficien.s. We show that it is con.in.ous in.all derivatives, lin.ar within.stable fluid phase, an. relates an.lytically to the Boyle-work lin. (BW) (w = (p/ρ)T = RT), an. to percolation.lin.s of gas (PB) an. liquid (PA) phases by: ρBW(T) = 2ρPA(T) = 3ρPB(T) = 3ρRS(T)/2 for T TB. These simple relation.hips arise, because the higher virial coefficien.s (bn./sub>, n.≥ 4) can.el due to clusterin. equilibria, or become n.gligible at all temperatures (0 T TB) within.the gas phase. The Boyle-work lin. (p/ρBW)T is related exactly at lower den.ities as T → TB, an. accurately for liquid den.ities, by ρBW(T) = −(b2/b3)T. The RS lin., ω(T) = RT, defin.s a n.w liquid-den.ity groun.-state physical con.tan. (ρRS(0) = (2/3)ρBW(0) for argon.. Given.the gas-liquid rigidity symmetry, the en.ire thermodyn.mic state fun.tion. below TB are obtain.ble from b2(T). A BW
