BIOL 2227 Chapter Notes - Chapter 11: Net Reproduction Rate, Exponential Growth, Metabolic Waste
Document Summary
Animals use different methods of dispersion to move around. Most invertebrates (insects and crustaceans have 2 stages of two different life stages. Since they are small moving from one place to another (dispersal) can be difficult and dangerous. 0 is the net reproductive rate (of females). It is the average number of offspring produced by an individual female over her lifetime. This combines the birth rate and density rate of individuals of a given age class. )/t (t is time positive (r) increasing pop) (while (r) is decreasing population. ) Birth rate- death rate (b-d) this is simplified version of equation. **on overage small organism have higher rates of per capita increase (r) and more variable population size than large organisms. The smaller the organism the more it reproduces. When there is abundant resources populations can grow at geometric or exponential rates.
