dinosaur social grouping revisited



As a postscript to a previous posting re: social
aggregation among dinosaurs (flocking/swarm
behaviour), a paper has reached me (available in pdf
form at her website):
Leah Edelstein-Keshet, 2001. Mathematical models of
swarming and social aggregation. Paper (7pp) presented
at the International Symposium on Nonlinear Theory &
Its Applications (NOLTA 2001), Miyagi, Japan, 28
October. 
Although insects and flying theropods have different
flight mechanisms, I have long thought that both
"swarm" or "flock". She has also published work which,
although not mentioned by Michael Crichton in his
bibliography, is germane to scholars who are working
with the subject:
Alex Mogilner & Leah Edelstein-Keshet, 1999. A
non-local model for a swarm. Jour. Mathematical
Biology 38(6):534-570
Leah Edelstein-Keshet, 1986. Mathematical theory for
plant-herbivore systems. Jour. Mathematical Biology
24(1):25-58
All of this is pertinent to speculations re: how, when
necessary, solitarious theropods will become
gregarious, hunting together (a pattern probably
common with Jurassic-Cretaceous theropods). Among
insects (primarily locusts), gregarious females will
have gregarious offspring, raising interesting
questions about vertebrate behavioural
ecomorphologies. An early paper by P.J. Conder (1949)
is worth perusing: Individual distance, Ibis
91:949-955.
Predator-prey dynamics are, hence, in need of further
modelling.
