Document Summary
In the fiels, global positioning systems (gps) permit ecologists to document precise locations and integrate them with other variables through gis. Importance of scale: scale: the spatial or temporal dimension of an object or process, characterized by grain and extent. These contemporaneous photographs illustrate a process that typically takes decades to complete a) an intact eucalyptus forest in western australia, b) areas within the forest have been. 6: roads; act as barriers to some wildlife, increase erosion, introduce invasive species and enable further human disturbance. Case study of habitat fragmentation: bighorn sheep in southern ca: fragmentation results in spatial isolation of population, making them vulnerable to the problems of small populations may go locally extinct within many of the fragments. 7: corridors did facilitate movement of butterflies, pollen and bird dispersed fruits, at the savannah river experiment, indigo bunting nest predation was higher in patches connected by corridors.
