The article discusses how adding dissipation to a nontwist map can create chaotic attractors that can suddenly expand, known as interior crises. Chaotic saddles, which are chaotic sets that don't attract, play a key role in this dynamic. The presence of two saddles can increase transient times, and crises can lead to intermittent behavior.
