Succession - Predictable sequence in species replacement in time (not random) Climax vegetation (end of the line) will stay the same unless the environment changes Example: Climax in North Carolina is Old Hickory in the forest. If you go to Northern Indiana it has a biome of deciduous forest. Would Northern Indiana have Hickories as its climax vegetation? No because the environment is different; the biome is different. Environment changes = species changes Need a source of seeds or animals if succession were to precede—source of immigrants, dispersal migration Diversity increases for all groups as succession proceeds because the environment grows more complex. Primary secession —there was no previously existing vegetation. You can find this in sand dunes because there is nothing growing on those dunes initially. Over time plants invade these dunes; succession proceeds. In order to see the pattern of change in time is that dune formation is progressive: younger, older, and older dunes. You can see progression as you move forward: Beach grass, then cottonwood trees, aspen trees, then pine forest much later, then oak forest, then oak hickory, then beach maple at the end of
