These two types of research, that is, in the laboratory and in the field, are very different from each other for a number of reasons. For one, the study is conducted on a much larger scale when it is done in the field as compared to when it is confined in the lab.
Tools such as PCR (polymerase chain reaction) would be common between the two since there is no substitute for it.
