This reflects the wide-spread occurrence of relatively arid climates towards the equator, and relatively more mesic climates towards the poles.
On the other hand, the wide-spread occurrence of evolutionary convergence implies that similar phenotypes can be found again with relative ease.
Despite the detected increasingly wide-spread occurrence of glyphosate residues in food, animal feed, water [5], air [13], human blood and human milk [14] and human urine [15, 80], it is not within the mandate of this review to evaluate whether the relatively high acceptance levels (MRLs) for glyphosate residues in food and feed are scientifically justified, however relevant the question may seem.
Finally, organism diverse subfamilies of prokaryotes suggests wide spread occurrence of such Ser/Thr kinases.
Similar wide-spread occurrence was observed for toxin-antitoxin loci [23].
Despite its wide-spread occurrence in the human genome, no report is available on the Y-linked genes.
In addition to the observed sequence and modular diversity, their wide-spread occurrence also indicates that CBM33s may have a wide variety of functionalities.
Despite the wide spread occurrence of Tc1-like transposons in vertebrates, not a single active gene has been identified to date [ 14].
These results show that the mapping of these individual conserved splice sites to its ancestor protein can reveal the wide-spread occurrence of these sites in ancient proteins.
Sequence-based analyses have demonstrated that some domains have ancient origin with wide spread occurrence in all three kingdoms of life, i.e. archaea, bacteria and eukarya [ 2], implying their indispensable role in fundamental cellular processes.
In spite of the size of the Columbia River basin and the wide-spread occurrence of contemporary spring-run populations (well represented in the mid- and upper-Columbia and Snake), overall genetic differentiation within this lineage is relatively low (only slightly larger than for Puget Sound, in spite of occupying a much larger geographic area; Waples et al. 2004 and D. T., unpublished data).
