Guest Lecs: Ranjeet John & Nan Lu Class web: http://research.eeescience.utoledo.edu/lees/teaching/eees4760_09/ Overview: from theory to applications
Landscape ecology has been featured with patch-corridor-matrix dogma -- a landscape is composed of multiple ecosystems. It is theorized that new structural and functional features would emerge when >2 ecosystems are placed together Chen & Saunders 2006

Landscape (Ecosystems) Or (Ecosystems) Landscape Why?
Understanding a landscape Are we satisfied with this product?
Understanding a landscape Is this structure of the landscape interesting and how was it created?
Understanding a landscape Is this structure of the landscape interesting and how was it created?
Can we create a similar landscape structure? What impacts can this structure have? Understanding a landscape Chen & Saunders 2006
Landscape Structure: patch-corridor-edge-matrix framework (FRAGSTATS, Fractals, Wavelet, Semivariance/Kriging, etc.) • Patch Patterns • Edges and AEI • Roads and Streams • Fragmentations • Landscape Process: movements of materials, energy and species across landscape • Landscape Dynamics: change over time • Landscape Models: HARVEST, Neutral Model, Moose, Tree2.0, LANDIS, etc. • Landscape Management: mimicking natural processes and arrange land mosaics in time and space
Landscape Analysis: • FRAGSTAT • Remote Sensing • Pattern-Process Relationships: • Fire and land mosaics • Species and structure (e.g., invasions) • Water and carbon • Gene flow and structure (not covered) • Landscape production
Landscapeis an area that is spatially heterogeneous in at least one factor of interest. Landscape Ecologyemphasizes the interaction between spatial pattern and ecological processes — that is, the causes and consequences of spatial heterogeneity across a range of scales (Turner et al. 2000) . • Not a science • Broader scales (mostly spatial) • Multiple ecosystems, their spatial arrangement and interactions • Applied scientific discipline • Multidisciplinary
Circle of Knowledge Creation The process of generating new knowledge comes full circle only when scientific understanding has been integrated into management and lessons from application are transferred back to validate or inform research studies. It is through this complete process that theories emerge. Tress et al. (2005)
