Modelling the effects of extreme events on the dynamics of the amphipod Corophium orientale

摘要: The brackish water amphipod Corophium orientale is the dominant macroinvertebrate species in upper Mira estuary, a small mesotidal system located southwest coast of Portugal. As climate changes will increase frequency and intensity extreme events such as floods droughts, these have negative effect on benthic estuarine invertebrates, namely C. orientale. In order to understand effects orientale, dynamic model, based published information calibrated with field data, was developed different scenarios were tested. For model construction, annual development three cohorts their growth rates, establishment timing each cohort rise extinction are introduced. This structure can be repeated indefinitely, for years, few parameters required. simulations highlight need refuge areas that enable fast recovery population after an event recolozination affected areas.
