Figure 2.
Species are identically ordered top to bottom and left to right according to the consensus partition as listed in Table 2. Hue indicates group identity; color saturation indicates the fraction of partitions in which species occupy the same group. Note that this image conveys information about group membership, not network connectivity.
Figure 3.
The network is shown organized and colored by group according to the consensus partition listed in Table 2, and arranged by trophic level from left (plants) to right (carnivores). Plants are identified by the first letter of identified habitat type, if available: (G)rassland, (W)oodland, (R)iparian, (K)opje, (S)hrubland, (T)hicket, and (D)isturbed. Plant groups are labeled by significantly overrepresented habitat types, and species assigned to the overrepresented type are labeled with black borders. An interactive version of this figure will be made available at http://edbaskerville.com/research/serengeti-food-web/.
Figure 4.
Network layout of aggregated groups.
Nodes in the network are aggregated and colored by group according to the consensus partition listed in Table 2, and arranged by trophic level from left (plants) to right (carnivores). Line thickness indicates the link density between groups. Node area increases with the number of species in a group.
