Figure 2. Network visualisation for Xenopus overland movement literature.

A network visualisation of literature mentioning overland movement in Xenopus using Gephi. Literature is sorted into that with data (left): anecdotal (squares), distributional (triangles), and mark-recapture (stars); literature reviews (middle: hexagons); and literature which does not have original data on overland movement in Xenopus (circles: right). Different species of Xenopus are denoted by different colours, and indigenous X. laevis (blue filled symbol) are differentiated from invasive populations (red filled blue symbol). Other species are coded as other colours: X. muelleri (green), X. borealis (pink), X. gilli (yellow), X. fraseri (grey), X. clivii (purple) and X. tropicalis (cyan). Curves connecting nodes denote the direction of the citation: above the line (right to left) or below the line (left to right). Nodes which are not connected represent literature which does not cite and has not been cited in relation to Xenopus movement overland.
