Coadaptive Dynamics of Cannibalism and Ovulation Synchrony: a Discrete-Time Mathematical Model

Carlton Cross

Dr. Shandelle Henson

Cannibalism and ovulation synchrony are common across many taxa. We consider discrete-time models to show that (1) cannibalism of juveniles by adults can be adaptive by redirecting reproductive effort from times of low resource to times of high resource, and (2) the immediate negative effects of cannibalism can be ameliorated through the synchronization of individuals' ovulation cycles within a dense population.

Shandelle Henson is professor and chair of mathematics and STEM division chair at Andrews University. As a dynamicist, she studies how things change over time. She notes, however, that in this system some things haven't changed over time, namely the friendship and mentorship that Ken and Tom have given consistently since she was a young mathematician first out of graduate school, and the respect and warm regards she has for them. As an "honorary" student of Ken and Tom, she is excited and honored to participate in this conference.
