Together, these results suggest that altitude may well be an important source of divergent selection within single rivers, and potentially acts on multiple independent loci.
Still, parallel altitudinal changes of AFLP band frequencies within multiple drainages indicate that altitude may well be an important source of divergent selection within rivers and suggest divergent adaptation in the face of gene flow.
Still, altitudinal divergence occurred and, at approximately 2% of the markers, parallel changes of the AFLP band frequencies with altitude were observed suggesting that altitude may well be an important source of divergent selection within rivers.
We believe that rather than being a source of confusion, these divergent findings present an intriguing avenue for future research.
Within both Globigerinoides ruber and Globigerinella siphonifera, subtle sub-types were found to display differing geographical distributions, implicating sea-surface productivity as a significant ecological source of divergent selection in closely related planktonic foraminiferal genetic types.
However, the source of divergent natural selection on stickleback body size could result from tradeoffs related to both feeding performance [41], [45] and parasite infection [14], [46].
This incongruity warrants additional research into the nature and source of divergent patient and provider perspectives on GWG counseling practices.
We conclude that routine genotyping data are useful for the detection of superinfection; however, extensive validation is required to exclude sample or sequence mix-up or contamination, which may be the most likely source of divergent virus sequences assigned to the samples of the same patient.
