摘要采用营养物-浮游植物-浮游动物（NPZ）模型和鱼类生物能量学模型，模拟了太平洋青鱼（Clupea pallasii）体重-年龄对气候变化的响应。NPZ模型通过模拟浮游植物和浮游动物对氮和硅的吸收和循环动态，以及多个功能基团的光合作用和放牧相互作用，表征了低营养水平的日常动态。生物能量学模型模拟了太平洋鲱鱼10个年龄组的数量和平均体重。在NPZ模型中模拟的三个浮游动物群提供了用于确定鲱鱼生物能量学模型的消耗成分的猎物的估计。我们使用产卵-招募关系来估计每年新加入鲱鱼种群的1岁个体的数量。将耦合模型应用于温哥华岛西海岸沿岸上升流区。进行了模型模拟，以隔离每种…
Abstract We used a nutrient-phytoplankton-zooplankton (NPZ) model coupled to a fish bioenergetics model to simulate the weight-at-age responses of Pacific herring Clupea pallasii to climate regimes. The NPZ model represents the daily dynamics of the lower trophic levels by simulating the uptake and recycling dynamics of nitrogen and silicon and the photosynthesis and grazing interactions of multiple functional groups of phytoplankton and zooplankton. The bioenergetics model simulates the number and mean weight of Pacific herring for each of 10 age-classes. Three zooplankton groups simulated in the NPZ model provide estimates of the prey used to determine the consumption component of the herring bioenergetics model. We used a spawner-recruit relationship to estimate the number of new age-1 individuals joining the herring population every year. The coupled models were applied to the coastal upwelling area off the west coast of Vancouver Island. Model simulations were performed to isolate the effects of each...
