Search Terms Scoping

An initial list of search terms (Table 1) was compiled using keywords from relevant articles and was tested against existing lists of articles derived from the libraries of colleagues and independent literature reviews for the Congo and Zambezi rivers. We found that relevant articles were returned from searches using a reduced version of only location and subject information terms. The final presented strategy reflects the revised set of terms.
