U.S.-Japan Cooperative Research: From Discrete to ContinuousModels for Ecological Interaction in Space and Time

该奖项将支持一个为期两年的美日合作科学研究项目，该项目由伍兹霍尔海洋研究所生物系的哈尔·卡斯韦尔博士和京都大学生物物理系的重赛纳子博士共同开展。研究人员将合作开发数学人口模型。这些模型旨在通过纳入当地人口空间结构的影响，比现有模型更真实地模拟人口过程。Caswell博士擅长于离散模型，而Shigesada博士则擅长于连续模型。研究的目的是探讨不同类型的时空模型之间的关系，特别是对离散和连续方法进行对比和比较。通过澄清不同类型的模型适用的条件，这项工作将广泛适用于对种群建模感兴趣的生态学家。

This award will support a two-year U.S.-Japan cooperative science research project between Dr. Hal Caswell, Biology Department, Woods Hole Oceanographic Institution, and Dr. Nanako Shigesada, Department of Biophysics, Kyoto University. The investigators will collaborate on the development of mathematical population models. The models are intended to simulate population processes more realistically than current models through the incorporation of the effects of spatial structuring in local populations. Dr. Caswell specializes in discrete models, while Dr. Shigesada specializes in continuous models. The objective of the research is to investigate the relationships among different classes of spatio-temporal models, particularly contrasting and comparing discrete and continuous approaches. By clarifying the conditions under which different kinds of models are appropriate, the work will be of widespread applicability to ecologists interested in population modelling.
