Simulating population recovery of an aquatic isopod: Effects of timing of stress and landscape structure.

摘要: In agroecosystems, organisms may regularly be exposed to anthropogenic stressors, e.g. pesticides. Species' sensitivity stress depends on toxicity, life-history, and landscape structure. We developed an individual-based model of isopod, Asellus aquaticus, explore how timing events affects population dynamics in a seasonal environment. Furthermore, we tested the relevance habitat connectivity spatial distribution for recovery local total population. The simulation results indicated that is mainly driven by reproductive periods. high led faster both populations. However, effects structure disappeared homogeneously stressed populations, where survivors increased rate. Finally, populations recovered faster, implying assessing field needs careful consideration scale sampling. emphasize need coherent definition more relevant ecosystem risk assessment management.
