Significant, positive associations between residuals and chemical constraints (Na, B, carbonates, pH) indicated lower limits greater than expected from texture, and less plant available water with increasing intensity of constraints.
The extent of rate differences suggests the intensity of selective constraints on these regions.
To assess the intensity of mutational constraints, we have considered all of the genes belonging to the core genome for all studied strains of Frankia, Mycobacterium and Streptomyces.
Hanson et al. (2003) analysed access constraints to scaling-up priority health interventions for the poor, whereby they used a five-level framework to capture the range and intensity of these constraints.
IC is based on a summation of the intensity of the selective constraints acting on each mutable component of the network.
This eventually led to differences in the intensity of the selective constraints acting upon the different H2A.Z forms in vertebrates.
These results suggest that the differences in the intensity of the selective constraints operating on H2A.Z-1 and H2A.Z-2 probarosearose during the differentiation of both variants from a common ancestor, represented here by H2A.Z-e from early chordates.
Consequently, the range and intensity of HRH-related constraints at five levels were considered: individual characteristics, the health service delivery level, the health sector level, training capacities and the sociopolitical and economic context of a country (Table 1).
The evolutionary process responsible for the differentiation between H2A.Z-1 and H2A.Z-2 has been described as a refined stepwise mutation change within the codons of the three differential residues (triresidue), leading to differences in the intensity of the selective constraints acting upon the two H2A.Z isoforms in vertebrates [ 24].
We further dissected the "total constraint intensity" of a gene into two components, the condition complexity, for which we refer to the number of environments (tissues) where the whole modules of the gene actively expressed, and the scale of the neighbor genes.
