Modeling host-parasitoid interactions with correlated events Gómez-Corral, Antonio López-García, M. In this paper, we present a host-parasitoid model with correlated events. We apply a block-structured state-dependent (BSDE) approach that provides a methodological tool to model state-dependent Markovian transitions operating in the presence of phases. A particularly appealing feature of the resulting BSDE host-parasitoid model is that it allows us to deal with non-exponential distributional assumptions on a host birth, a parasitoid death, and parasitism, but keeping the dimensionality of the underlying block-structured Markov chain tractable. Numerical examples are presented to illustrate the effects of the correlation structure on the expected extinction times and the extinction probabilities. 2023-06-19T13:21:33Z 2023-06-19T13:21:33Z 2023-06-19T13:21:33Z 2013-04 journal article https://hdl.handle.net/20.500.14352/33290 0307-904X 10.1016/j.apm.2012.10.035 eng MTM-2011-23864 BES-2009-018747 restricted access Elsevier Science Inc
