- State and explain the three (3) patterns of species dispersion.
- Give an example of antagonistic social interaction.
- How would a uniform dispersion of a population of penguins appear from an airplane flying above them? What determines such a variability?
- Identify the three characteristics of demography, and how is its information put to use?
- Summarize the steps of a “life table”.
- What key element do scientists focus upon their work with “life table”?
- Be able to examine and analyze a life table such as Table 53.1, that is based upon the Female Belding’s Ground Squirrels.
- Define survivorship curve.
- Examine figure 53.5: Survivorship Curve for the Female Belding’s Ground Squirrels, and answer the following: What percentage of females survive to be three years old?
- Explain the three (3) types of survivorship curves and provide an example of each.
- Provide a reasonable analysis among the variation of the survivorship curves based on specific organisms.
- When a species is not influenced by its kind that moves in or out of its area, what are the two key variables that affect the size of a population?
- What is the significance of the ecological exponential model?
- State the equation for the change in a population size verbally and mathematically.
- Define: per capita change in population size. Rewrite the equation in question # 26.
- Ecologists use the term “intrinsic rate of increase” identified by “r”. What does that mean? Describe the graphic shape of that exponential growth.
- Examine figure 53.8: Population Growth Predicted by the Exponential Model, and answer the following: How many generations does it take these populations to reach the size of 1500 individuals?
- What do you think can be the outcome of an exponential growth of a population over time?
- How does a logistic model differ from an exponential model?
- Define “carrying capacity”.
- List the six (6) variables that can influence the carrying capacity.
- If the population size approaches the carrying capacity, what can happen to the per capita population growth?
- What happens when the population size (N) equals the carrying capacity (K)?
- Describe the graphic shape of the logistic model. Again, what key factor influences it?
- When (N) approaches (K), what factors are influencing them?
- In reality, sometimes the carrying capacity is overcome temporarily . What variable causes such action?
- What evolutionary outcomes of the life history traits of an organism are influenced by?
- Contrast semelparity and iteroparity and provide two examples of organisms for each.
- Give an example of a trade-offs among certain birds or mammals.
- Read and examine figure 53.14: Inquiry, and answer “Interpreting the Data” question.
- Distinguish between K-selection and r-selection.
- Contrast density-dependent with density-independent.
- When does population density equilibrium occur?
- How does the principle of feedback regulation work. Give an example of it.
- List six (6) mechanisms of density-dependent population.
- What is the premise of population dynamics?
- In figure 53.19, describe the relationship between the wolves and the moose.
- Examine the figure 53.20, Population Cycles in the Snowshoe Hare and the Lynx, and answer the following: What do you observe about the relative timing of the peaks of lynx numbers and hare numbers? What may explain this observation?
- Define metapopulation and explain an example of it. What contributes to a such formation?
- Why has the human population growth slowed down in recent decades?
- Define demographic transition. What is believed to be its contributing variables?
- How does total reproductive rates compare in industrialized countries to those non-industrialized countries?
- In general terms, how would you describe the age structure in Asia, North America, and Europe? Are there any variables that you would consider that would influence or change such an age structure in any of these continents?
- If infant mortality is high in a region, what can be expected of parents in that region?
- Define an ecological footprint. What is the benchmark for your ecological footprint? How does it compare to your actual ecological footprint in the U.S.? (Food for thought)
- If everyone on Earth lives like we do in the U.S., how many people could Earth support?
****Concept Check 53.1, 53.2, 53.3, 53.4, 53.5, and 53.6 have a set of three (3) questions each; they’re oriented toward AP Style testing essays that involves your critical thinking skills. These questions are highly recommended if you are considering on taking the College AP Exam in the spring.****
