Environmental biology notes Succession – gradual transition from one plant and fauna to another Biological Surplus Carrying Capacity Limiting Factors - Accident Weather, Disease, Hunger, Predators, Aged Age, Hunting. Turnover- When a new person replaces the old one. High Capacity - Unlimited population growth resulting in a maximum increase of for this population. Reproduction Ability to migrate (animals) or dispersal (seeds) Ability to enter new areas. Defense Mechanisms Ability to withstand adverse situations. Environmental Resistance - The sum of environmental factors that appear to be limits the ability of bacteria. No food or supplies No water No shelter Bad weather In the wild - survival of the fittest; gene pool under natural selection. Native gene pools subject to human influence. Wild species were once disturbed by humans, but now are subject to natural selection. Exponential Growth - growth at a constant rate. Natural Selection- Influenced by the natural environment, only brings auxiliary changes and adapts the organism to produce offspring that can survive better and protect the environment. Found in the crowd. The size of the core pool can be increased or decreased. It takes time to be special. Genetic Drift - the mechanism of evolution due to chance or chance. Adaptation is not occurring. Few people saw it. It can be useful or problematic. It cannot cause speciation. The size of the gene library can be reduced.

Demography - the study of statistics describing changes in human population patterns, such as births, deaths, incomes, or incidence of disease. Population growth reasons 1. Migration to new regions and climates. 2. Early and modern agriculture. 3.
