Document Summary
Loss of predators will accelerate co2 accumulation: herbivores will be suppress- increase the amount of plants, plants where carbon is stored, if makes into deep ocean- will store- in deep water, 3 different environments- pond, stream, bromeliad. Compare shaded boxes with predators- non shaded without predators. When no predators- increase in co2 flux (change per unit time) Climate change 1: dramatic shifts in habitat predicted: plants move down because of glaciation, move up- when re glaciate, north and south temperature changing faster. Therefore, climate change affects temperate ecosystems more than tropics. Move south after glaciation: tropics- have consistent environment. Then organisms- have evolved in narrow environmental ranges. Then small change in environment can affect them more. Arguments= not an actual fact: climate change- change in temperature, precipitation, other environmental variables. Since other factors- not just temperature then not just moving north- can shift around east and west.
