Ecosystems & Communities Succession �The sequential change that happens in an ecosystem over time after a disturbance �Primary Succession that begins in an area with NO remnants of an older community � Takes a lot of time (depends on location) Pioneer Species � The first species to colonize barren areas Ex. Lichens, grasses • Over time – these fix N 2, break down rock, add organic material to form soil.

Ecosystems & Communities Succession �Secondary Succession that occurs after a disturbance that does not completely destroy the ecosystem. � Occurs much faster than primary succession

Ecosystems & Communities Climax Communities �Do ecosystems return to “normal” following a disturbance? After Natural Disturbances � Secondary succession in healthy ecosystems often reproduce the original climax community Climax Community – the specific overriding flora & fauna in “adult” communities…usually call it a biome. After Human-Caused Disturbances � Ecosystems may or may not recover from extensive humancaused disturbances. � Can cause too large of changes in the microclimate & soil for nature to recover from

Biomes �Why does the character of biological communities vary from one place to another? �Why, for example, do temperate forests grown in the Pacific Northwest while areas to the east of the Cascades are much drier? �How do similar conditions shape ecosystems elsewhere?
