Document Summary
Heterogeneous landscapes landscape ecology- sub-disciple of ecology that emphasizes the causes and consequences of spatial variation across a range of scales landscape elements: Abiotic: topography: rise and fall of landscape (eg. mountains, lowlands) Depends a lot on soils (ie. weathered, old, new) landscape: Heterogenous: displays a varied composition or mixture of elements; man differences in spatial and/or temporal scales (i. e season) Homogenous: consists of elements which are similar or identical; few or no differences across space/ time ie. field of corn. Mosaic: composite of heterogeneous elements (eg. google map) Moist calcerous soils correlates with upland evergreen forest landscape ecology depends a lot on knowing topography and soil composition. Geographic information system (gis): used in landscape planning, for conservation and urban development. Global position systems (gps): allows ecologists to document precise locations and integrate them with other variables through gis. Can come with different layers (different sets of data that is combined with gis data) of information.
