Forest Dynamics of Riparian Corridors

美国中西部森林覆盖的河床很重要 这是该地区整个生态系统的组成部分。 他们很关键 水的流动和保留的决定因素，他们是强烈的 受人为变化的影响，如水坝和渠化。 它们也是影响植被物种变化的主要地点。 马兰森教授将研究幼苗建立和树木生长 在爱荷华州的两个筑坝和管理较少的河流，并确定 成苗与生长、淹水、土壤 水分和光照与物种扩散的关系。 现场数据将 可以用来建立一个数学模型， 不同类型河流廊道的建植和树木生长。 马兰森教授的研究将扩大我们对 造成短期和长期植被变化的过程 管理和未管理的河岸区。

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.
