RAPELD - A measurement and analysis of scholarly literature.

Figure 1. International links of the RAPELD system based on a scientometric study of >100 publications. The thickness of lines is proportional to the number of joint authors. There are links to many parts of the World, but the majority of connections are to a limited number of countries, a situation that should change as RAPELD is adopted in more regions. 

Figure 2. Interactions among species groups and some non-biological environmental characteristics that have been studied in RAPELD plots. The graph is based on a scientometric study of >100 recent publications and line thickness is proportional to the number of studies that investigated the relationship between the linked variables. This illustrates that RAPELD methodology is useful for integrated research and also indicates the relationships that are in need of more intensive research.
