Topic: Climate Effects on Species Distribution (Chapter 45):
Question:
What abiotic factors impact global patterns of animal distribution?
What is a biome? And what are they characterized by in both aquatic (water) and terrestrial (land) areas? What are the different biomes?
Understand the three-cell model and how to predict the latitude biome position.
What % of earth does freshwater cover?
Be able to explain how and why a mountain can show several major biomes from the bottom to the top of the mountain.
Population Growth and Species Interaction (Chapter 43):
What is the definition of a population and how are populations studied?
Explain the different ways that ecologists measure populations for specific organisms. Define population density.
Understand the variables that go into a life table and how to interpret those variables in a life table.
Be able to identify the 3 different survivorship curves. Also, explain and give an example of an organism that exhibits each type of curve.
Be able to distinguish between exponential and logistic growth models. Understand the mathematical model for each and what the terms mean.
What is meant by carrying capacity? What is it that causes a population to have a carrying capacity?
Interactions between species can be defined by the effect on the populations concerned. Be able to name and identify the + or - interactions between species.
Know the difference between intraspecific and interspecific competition.
Be able to explain the competitive exclusion principle & how resource partitioning affects this principle.
Understand the different adaptations that prey species have gained to reduce predation on the population and be able to give an example of each.
Communities and Ecosystems (Chapter 44):
Explain the patterns of species richness and how they vary.
What is species richness? species diversity? What is the difference between the two? How do you calculate species diversity?
Explain the intermediate-disturbance hypothesis and how to study it.
What is the name of the process that occurs after disturbances that are the system trying to reset itself? Be able to distinguish between primary and secondary when it comes to this process.
Be able to explain the 3 different successional models: Facilitation, Inhibition & Tolerance.
Understand the ideas behind the island biogeography model. What is the equilibrium point and balance between? How does the size of the island and distance from the mainland influence the equilibrium point?
Understand the feeding relationships among the various species in a community and how they impact each other. They can be represented by chains or webs.
When it comes to food chains and webs, understand the following terms: Producers, consumers, primary consumers, secondary consumers, tertiary consumers, decomposers.
Understand the energy transfer of food webs and why energy is lost as you go up the food chain/web.
The Age of Humans (Chapters 46):
What is age structure and TFR and how does it influence the predictions on future human population? Be able to look at an age structure and total fertility rate graphs and decipher information on them.
Discuss the main factors that are correlated to lower population growth.
What are the 4 main human caused factors to the loss of biodiversity? Be able to explain and give examples of each one?
What is an ecological footprint and what is the average footprint worldwide?
What is Biomagnification? How does it work in a food web or chain?
What are the 3 main biogeochemical cycles discussed? For each one, understand why the cycling of that chemical is important to life, what the abiotic reservoir is for each one, and how humans have influenced/altered the cycle.
What are the consequences of global warming?
What is the greenhouse effect and what are the greenhouse gasses?
