We found a strong positive relationship between the LT50 and both maximum habitat temperatures and the breadth of temperatures experience across the species' ranges.
In general, the increases in tan δ peak temperature, tan δ peak breadth, and room temperature modulus with increasing TEOS content are similar to those observed with POSS and VSQ.
Because of the characteristic evolution of integral breadth with temperature as depicted in Figure 3 the changes observed were interpreted in terms of varying disorder in the crystallites of Mo(O,N 3.
Of course physiology plays an important role in the distribution of taxa across geochemical and temperature gradients, so habitat breadth and physiology are not necessarily independent.
In particular, it was shown that the breadth of the temperature span of the crystalline nematic transition correlated inversely with the draw down ratio.
DMA reveals that PTMO-based PHUs have broad interphases with a range of local compositions and glass transition temperatures (Tgs), with tan δ ≥ 0.3 over temperature ranges exceeding 70 °C in breadth.
In general, it is observed that network compositions with larger amounts of short, stiff 4,4'-methylenebis cyclohexylamine) (MCA) cross-linkers lead to an increase in the mechanical glass transition temperature as well as the breadth of the glass transition compared to longer, more flexible poly(oxypropylene) diamine (POP) cross-linkers.
Because correlative evidence suggests that invasiveness is related to the width of a species' latitudinal range, it has been assumed – but largely untested – that range width predicts breadth of habitat temperatures and physiological thermotolerances.
However, neither the fragility (Tg-normalized temperature dependence of τα) nor the breadth of the relaxation dispersion were affected by the geometric confinement.
A systematic decrease in the breadth of the service temperature window and mechanical properties of the polyureas were observed in the presence of LiCl, due to the disruption of the long range connectivity between the hard segments.
