Population Ecology
Study Guide/Practice
Be able to define and apply all vocabulary from Chapter 35
35.1 Populations are a local group of one species
Define the types of boundaries and examples of both
Population Density vs. Population Size
Defining a species
Types of distribution and examples
Types of Sampling Techniques and examples
35.2 There are limits to population growth
Understand the types of limiting factors and what a limiting factor is
Density Dependent vs. Independent
The meaning of exponential (J-shaped graph) and carrying capacity (S-shaped graph)
Types and definitions of Survivorship graphs and examples
35.3 Species interact in a biological community
 Interspecific Competition vs. Competitive Exclusion (there is a huge difference!!)
 All species interactions (Predation, Symbiotic relationships) and examples
 Compare and contrast Niche vs. Habitat
35.4 Disturbances in communities
 Types of natural disturbances and how they can be positive or negative (including
 Types of Ecological Succession and define Ecological Succession
 Impacts of human activities (invasive species, clear cutting, etc…)
35.5 Predicting the growth of human population
History of human population growth (1 C.E. → 2000 C.E.) and factors effecting it
The human population graph
Age structure graphs and the types of age structure graphs w/ examples
What the type of age structure predicts about the future
