Aggregate monsters: ecologies challenging encounters by Matt Horrigan, https://analoggamestudies.org/2021/10/aggregate-monsters-ecologies-challenging-encounters/, has several threads. First, it claims without support that encounters are a very distinct and walled-off part of D&D play. The second thread is about how the game master can only run monsters fairly bereft of inner live and ecology due to limits of mental processing. The third thread discusses monsters that are collectives of smaller creatures. There is an attempt to tie these threads together so as to have implications in the current political climate of USA. The author leaves unstated which edition of D&D they discuss; it seems to be one where monsters one encounters are almost always a reason to fight, and where distracting oozes with food is unheard of.
