The acclimation response ratio (ARR) calculated as an index to assess the magnitude of thermal acclimation of organisms.
where CT[m.sup.2]-CT[m.sub.1] represents the difference between values of critical temperatures (max or min) within the whole acclimation temperature range examined (A[T.sub.2]-A[T.sub.1]).
Nine specimens were selected from each acclimation temperature (n = 45).
For each acclimation temperature, ten individuals used to calculate TIMRMax and ten for TIMRMin according to the novel methodology proposed.
C[T.sub.min] median values were 10.5, 12.6, 13.3, 14.0 and 14.9[degrees]C (at respective acclimation temperature of 20, 23, 26, 29 and 32[degrees]C).
Although levels of Hsp70 in the Sunset Bay (SB) population did significantly increase as incubation temperature increased, those levels were not affected by acclimation temperature alone (Fig.
Levels of Hsp90 did not vary significantly as a function of acclimation or incubation temperature in the CH population; no recognizable patterns were observed (Fig.
4 and 6) indicated that Hsp70 is induced in Balanus glandula at 23 [degrees]C, regardless of acclimatization or acclimation, indicating that heat-shock proteins are upregulated in this species on a regular basis.
Increases in acclimation or acclimatization temperature are typically associated with upward shifts in the induction temperature of heat-shock proteins (Dietz and Somero, 1992; Tomanek and Somero, 1999; Buckley et al., 2001; Buckley and Hofmann, 2002).

Increase in cell size underlies neuron-specific temperature acclimation
Our results, however, only partially supported our hypotheses in that we did observe respiratory acclimation, and this acclimation did result from a decrease in EO with increasing growth temperature, as expected.
It is important that more studies be conducted with more drastic nitrogen limitations imposed to tease out the mechanistic underpinnings of nutrient limitations on thermal acclimation of leaf dark respiration.
