Zebra Graphs

Science News has an article on how understanding the structure of dynamic interactions between social entities explains their behavior. The nodes are Zebras and the edges link Zebras that are near each other during some time. You study the structure of these time varying graphs to figure out
is there a change in the Zebras' interactions just before a bachelor overthrows a stallion in a coup? When Zebras flee a lion, how do they decide which Zebra will lead the stampede?..
The article is well written (Facebook hasn't yet opened up a site for zebras.), contains two useful references, and it showcases a genuine example of algorithmic thinking and problem-solving by Berger-Wolf that impacts Biology.
