摘要采用个体模型比较了深水库和浅水库中不同水位波动幅度和周期条件下小口黑鲈和白色刺蛾的繁殖成功率。该模型模拟巢址选择，蛋沉积，以及随后的发展和生存的年轻人从鸡蛋通过分散在一个二维空间网格的栖息地细胞代表水库底部。所有模拟均针对5月至9月，使用每日时间步长。巢址（细胞）的选择是根据基质，坡度，深度和结构的物种特定的栖息地适宜性指数。幼鱼的发育取决于温度。死亡率通过损耗、遗弃和全巢灾难发生。模型确证进行了观察嵌套白色蟹和smallmouth低音布朗利水库，莎士比亚俄勒冈州。预测的卵到扩散存活率随时间的延长而下降。
Abstract An individual-based model of nesting smallmouth bass Micropterus dolomieu and white crappie Pomoxis annularis is used to compare reproductive success in a deep reservoir and a shallow reservoir under different amplitudes and periods of water-level fluctuations. The model simulates nest site selection, egg deposition, and the subsequent development and survival of young from eggs through dispersal in a two-dimensional spatial grid of habitat cells representing the reservoir bottom. All simulations are for May through September using a daily time step. Nest site (cell) selection is determined from species-specific habitat suitability indices based on substrate, slope, depth, and structure. The development of the young is temperature dependent. Mortality occurs via attrition, abandonment, and whole-nest catastrophe. Model corroboration was performed with observations of nesting white crappies and smallmouth bass in Brownlee Reservoir, Idaho–Oregon. The predicted egg-to-dispersal survival declined wi...
