Although this novel technique appears promising and would substantially reduce reporting times, the results need to be substantiated by further larger studies.
Health claims need to be substantiated scientifically.
The available limited prospective data in small samples need to be substantiated by a longitudinal approach in larger at-risk cohorts.
This shift in ruminal bacterial communities and higher CH4 emissions could imply increased ruminal digestion of feed, which needs to be substantiated in longer term studies.
Finally, the solution-focused approach needs to be substantiated in terms of solution scenarios pertinent to the problem of concern, i.e. emissions and risks of chemicals in surface waters.
Composition data and transport models need to be substantiated, etc.
We cannot conclude, on the basis of the above examples alone, that anti-semitism has increased in Turkey, a claim which needs to be substantiated by further research and cross-time comparisons.
To this extent reports of pathogenic bacteria (i.e., R. prowazekii) in unusual vectors need to be substantiated beyond simple detection in these foreign hosts, and caution should be taken when immediately assigning novel host associations.
This basic assumption needs to be substantiated, especially as it seems unlikely that no costs are associated with this trait cf. Roff [30] but see Cam et al. [55].
Even though this hypothesis needs to be substantiated by more observations from different canyon and channel systems, it corroborates the Dynamic Equilibrium Model and there are other indications for its validity.
