Document Summary
Ecosystem ecology: study of interactions among organisms and their physical environment as an integrated system. A way of looking at organisms and their interactions with the environment as an integrated system. Focuses and functions, processes, fluexes and biogeochemical cycles. Inputs, outputs, feedback loops, resistance and resilience and emergent properties. Boundary between biotic and abiotic components is often blurred. -> provides a mechanistic basis for understanding earth"s systems. Ecosystems are nested and hierarchical thus we can study them on a number of different spatial and temporal scales. Spatial boundaries: indistinct, organisms can move between aquativ and terrestrial environment, trees drop leaves into pond. Temporal scale: instantaneous, seasonal, successional, evolutrionary history and geologic history.
