Measurement and classification differences in the calculation of the FRR further constrain comparison of these four studies.
Contrasts in the types and distribution of trophic resources between terrestrial and marine environments and fundamental differences in the physical properties of water and air constrain foraging modes among marine tetrapods [ 6].
This large variation undoubtedly reflects major differences in the visual ecology of different squid species, and speaks against the conclusion of Schmitz et al. [ 1] that eye size is developmentally constrained in squid.
Therefore, the large differences in the values of enthalpy and entropy for Cp149red and Cp149ox must be related, at least in part, to the conformational changes in the free dimer constrained by the C61 C61 disulfide.
In addition, there are likely to be differences in the risk of sperm loss or dilution, so that any trade-off between sperm size and number might also vary between these taxa and differentially constrain the evolution of sperm morphology.
The difference between both analysis may reflect differences in selective constrains through the action of purifying selection being higher in the upstream part of the pathway rather than differences in the selective pressures by means of positive selection.
There were no gross differences in the numbers or frequencies of donor cells in PBS-treated hosts, indicating that PD-1 expression does not constrain the accumulation of donor cells in the absence of PIT.
Although the lower layer gradient is rather poorly constrained, the significant difference in the values of (V_{p}^{prime }) anomalies relative to PREM between the two layers is robust; the anomaly of (V_{p}^{prime }) with respect to PREM ((dV_{p}^{prime })= d V p/d r profile - d V p/d r PREM ) is much larger in the shallower part of the depth range considered than below it (Fig. 8).
The significance of the difference in the sum of the site-wise log likelihoods of the two trees (unconstrained versus constrained) was then assessed using the SH test.
In Figure S2, we show the coefficient differences between the constrained and unconstrained solutions to degree 900, normalized by GRGM900C.
