报告摘要：Tick population dynamics has been an important and classical example of biological systems with physiologically structured individuals going through multiple development stages. Nonlinearity is often attributed to the density-dependent reproduction rate, but recent studies show a certain nonlinearity emerges from the dynamic interaction of tick attaching (to the host) and host grooming behaviors, both modulated by the feeding tick loads on the host. Some preliminary studies also show that this emerging nonlinearity also impacts on the multi-stability of tick population dynamics. This, in conjunction with the so-called diapause triggered by environmental conditions, has significant impact on the co-occurrence on hosts of multi-cohorts of ticks, and of the efficacy of tick-borne pathogen transmission through the so-called co-feeding transmission route. This talk presents some biological motivation as well as some preliminary mathematical analyses (including modeling frameworks). This is based on some joint work with Xue Zhang.
