Document Summary
Geographic information systems (gis) used for landscape planning, for conservation and urban development. Conditions and vegetation preferred by lark buntings mapped to predict distribution. Locations of conservation lands mapped on another showed that only a small portion of bird"s range is in protected areas. Global positioning systems (gps) allow ecologists to document precise locations of species and other variables. Radiotelemetry allows tracking of animal movements and migration patterns. Landscape ecology: emphasizes the cause and consequences of spatial variation across a range of scales. Look at spatial arrangement of landscape elements - ex. forest patches, soil types, etc These patterns influence what species live in an area and the dynamics of ecological processes. Landscape: area in which at least 1 element is spatially heterogeneous, often includes multiple ecosystems. Landscape composition kinds of elements or patches and how much of each kind is present.
