Experiments that are controlled and carried out in artificial situations may be argued to lack ecological validity, as behaviour in these situations may be affected by the fact that a participant knows that they are taking part in an experiment; a factor which does not affect field studies in real situations.
Different types of commercial enological tannins (mainly hydro-lyzable, condensed and blends of the two) could be recognized.

Experimental studies of neopolyploids provide critical insights into the relationship between polyploidy and adaptation. The approach is not perfect, however, and several caveats are acknowledged. First, polyploidy may originate in a genetic background that responded to genome duplication somewhat differently than current-day populations that.

With both laboratory and case studies there are strengths and weaknesses as with any other method. Laboratory experiments tend to lack ecological validity, this is because as the setting is artificial it makes it difficult to generalize any results to wider society because you can never guarantee that the results gained from the experiments will be the same for the population.
