  1. Landscape Limnology Christopher Bednar Division of Natural Science and Mathematics Keystone College

  2. Introduction • Landscape limnologyis the spatially-explicit study of lakes, streams, and wetlands as they interact with freshwater, terrestrial, and human landscapes to determine the effects of pattern on ecosystem processes across temporal and spatial scales. (Sorannoet al. 2010) • Several Themes • Patch Characteristics • Connectivity and Directionality • Spatial Hierarchy

  3. Uses • Study aquatic ecosystems • Identify patch characteristics • Identify interactions with other systems • Identify its scale and hierarchal position • Models • Relationships between multiple systems Source: Soranno (2009)

  4. Implications • Concepts used for continued research • Environmental management • Urban development • Wildlife conservation • Wetland studies • Examples • TransCanada Keystone XL Pipeline • New Orleans urban development and Mississippi River • Colorado River draining
