Even in well-replicated studies with high numbers of control sites, separating the effects of spatial seascape variation from those of protection can be difficult given that a procedural framework is lacking for selecting appropriate control sites within a heterogeneous seascape [10].
These administration techniques usually produce considerable variation in the individual antibody immune responses of vaccinated birds, indicating potential variation in the levels of protection after vaccination (Senne et al., 2004).
These costs may provide a means of maintaining the genetic variation in protection against competing fungi that is required for the evolution of adaptation to fungal competitors.
Use of a 'regional value' on synthetic logging coupes showed a wide variation in the level of protection given in such areas.
We ask too whether the variation in the level of protection across the PAs within a national network is correlated with these indicators of low threat.
However, it was noted that there was considerable variation in the levels of protection achieved with this approach.
While traditional synthetic methods accomplish the synthesis of hexoses using variations of iterative protection-deprotection strategies, requiring 8 14 steps, organocatalysis can access many of the same substrates using an efficient two-step protocol involving the proline-catalyzed dimerization of alpha-oxyaldehydes followed by tandem Mukaiyama aldol cyclization.
If this finding is confirmed, then the effect of latitude would be consistent with the variation in protection by BCG against pulmonary disease.
17 Similarly, the small number of studies limited the power to explore whether the variation in protection by BCG against tuberculosis is mostly through variation in protection against infection.
Also, our study showed a high degree of individual variation in exposure protection.
However, there is also great variation among individual ecoregions attaining 38% of protection whereas others have none.
