Document Summary
Landscape ecology: landscape structure heterogeneity in the landscape, landscape processes, fragmentation and edge effects. Landscape ecology (fig 21. 14: abiotic patterns and processes, biotic processes and patterns (communities, ecosystems and populations, landscape structure intersects biotic and abiotic processes. Describing landscapes: vary significantly; alberta is a diverse province in terms of landscape heterogeneity (rocky mountains in the western side, boreal forest etc. , large scale geological processes (sedimentation) affect landscape structure. Landscape structure (fig 21. 10, 21. 11, 21. 12: patches in the matrix (area between the patch), size (matters in terms of the type of species, which can persist in that environment. In boston, there are fewer but larger patches, the proportion of forests is large: shape (determines how much edge there is, different distribution of species, depending of mobility of organisms and environmental factors, composition, number, position. Animals in fragmented landscape (smaller patches) will have to travel longer distances.
