Secondary SuccessionCC BY-SA 3.0 Katelyn Murphy - Own work An example of Secondary Succession by stages: 1. A stable deciduous forest community 2. A disturbance, such as a wild fire, destroys the forest 3. The fire burns the forest to the ground 4. The fire leaves behind empty, but not destroyed, soil 5. Grasses and other herbaceous plants grow back first 6. Small bushes and trees begin to colonize the area 7. Fast growing evergreen trees develop to their fullest, while shade- tolerant trees develop in the understory 8. The short-lived and shade intolerant evergreen trees die as the larger deciduous trees overtop them. The ecosystem is now back to a similar state to where it began. 29.

(Ecosystem diversity) { (Predatoion), (Competition), (Symbiosis)} { (complexity), - (Carrying Capacity), } 31. Populations must not exceed the carrying capacity of their environments!!! If the carrying capacity of the environment is exceeded, organisms die and the environment may be permanently destroyed. 32.

The canyon depth here is approximately 600 meters, where the river has gradually cut a wide separation of the original continuous habitat of the Colorado Plateau. Temperate zone 37. Transition Zones (Ecotones) Transition Zone - Agricultural Area on Santa Cruz Island. Transition Zone on Floreana Island Transition Zone - disused agricultural area on Floreana Island An ecotone is a transition area between two biomes. 38.

Number of butterflies caught in a light trap at Rothamstead, England. The most abundant species (on the right of the diagram) are not illustrated. Total of 6814 individuals, 37 species only with a single specimen, 1799 specimens belonged to one very common species, 6 common species comprised 50% of the catch. Modified after 45. The percentage of wetlands supporting each species is represented by the size of the circle within each richness level (nested structure; observed matrix temperature = 20.47; average null model matrix temperature = 69.13; P|0.87|) on a single principal component (eigenvalue = 3.5, 89% of variation). Images were provided by G. Nafis (A. californiense) and D. Preston (all others). 46. (Spatial Parameter, Wilson, 1963) (Area effect) ; (Distance effect); 47. ; (Dispersal) 48. (Colonization) 49.

The greatest loss with the longest-lasting effects from the ongoing destruction of wilderness will be the mass extinction of species that provide Earth with biodiversity. Although great extinctions have occurred in the past, none has occurred as rapidly or has been so much the result of the actions of a single species. The extinction rate of today may be 1,000 to 10,000 times the biological normal, or background, extinction rate of 1-10 species extinctions per year. Rhett Butler | Last updated July 22, 2012 55.
