In semi-natural grasslands, the accumulation of dead plant material over the course of natural succession on nutrient-poor mineral substrates can lead to 'dramatic changes' in the soil (Berendse, 1998, p. 85).
These types of cloning have the potential to have a greater effect than changing the lives of pet owners or the livestock industry; it could change the course of natural history on our planet.
For another, he espouses a form of the mechanical philosophy, albeit one that departs from orthodoxy (as pronounced by Gassendi) in that God plays a significant and sustained role in determining the course of natural phenomena.
This methodology will produce misleading predictions and evidence judgments about the course of natural selection, however, if groups (in some contexts) or genes (in other contexts) are also evolutionary individuals, as many have argued.
The specific management conditions that may influence the course of natural infections and consequently determine treatment schemes are mentioned and suggestions for best practice in sampling and evaluation of data prior to conducting of efficacy studies are given.
However, isolation of protective neutralizing antibodies has been challenging for some viruses, notably those with high antigenic diversity or those that do not elicit a bNAb response in the course of natural infection.
During the course of natural HIV-1 infection, nAbs are generated that may delay disease progression (reviewed in [4]).
Thus, conserved regions of the HIV-1 proteome included in the HIVCONSV immunogen served as a source of T cell epitopes immunogenic during the course of natural HIV-1 infection.
While the evolution of cooperation and altruism are often seen as paradoxical events in the course of natural selection, endosymbiosis has been recognized as a driver of evolutionary change.
There is clear evidence that HIV-1 variant strains that escape CTL surveillance (due to impaired MHC binding, TCR recognition or proteasomal processing) evolve during the course of natural infection [4] [8].
The 2F5 mAb, like all other HIV-1 bnAbs, is not normally made during the course of natural HIV-1 infection, nor can it be elicited in any species immunized by current HIV-1 immunogens.
