Review both articles looking for how terms were used and especially looking for

Review both articles looking for how terms were used and especially looking for how they developed/described their study design including such key issues as the sampling frame (was it defined?) and target population. Also look at their sample sizes and how they were divided (as appropriate for the study) by space and time (e.g. by vegetation categories by sex or age). Write up your findings but spend few words describing the study and methods and most of your words on a critique of the study design (i.e. do not review their methods and results).
Take note: DO NOT REVIEW METHODS and RESULTS in the TWO ARTICLES
