Forested stream beds in the American Midwest are important components of the overall ecosystem of the region. They are critical determinants of water flow and retention, and they are strongly affected by human-induced changes such as dams and channelization. They are also major sites that affect vegetation species changes. Professor Malanson will examine seedling establishment and tree growth in both dammed and less managed rivers in Iowa and determine the relationships among seedling establishment and growth, flooding, soil moisture, and light, in relation to species dispersal. Field data will be used to develop a mathematical model that simulates seedling establishment and tree growth in different kinds of river corridors. Professor Malanson's research will enlarge our understanding of processes producing short- and long-term vegetational change in both managed and unmanaged riparian areas.

美国中西部的森林河床是该地区整个生态系统的重要组成部分。它们是水流和蓄水的关键决定因素，并受到人为变化（如水坝和渠化）的强烈影响。它们也是影响植被物种变化的主要场所。Malanson教授将在爱荷华州的水坝和管理较少的河流中检查幼苗的建立和树木的生长，并确定幼苗的建立和生长、洪水、土壤湿度和光照之间的关系，以及与物种扩散的关系。野外数据将用于建立一个数学模型，模拟不同类型河流廊道的幼苗建立和树木生长。Malanson教授的研究将扩大我们对在管理和未管理的河岸地区产生短期和长期植被变化的过程的理解。
