survivorship curves
Lesson Outline
Examination and analysis of the 3 types of survivorship curves as seen on a diagram, along with examples of organisms which fall into each category.
Define and explain using drawings, the term meta populations. Elicit why distinct populations will form from what was once a single population.

Session Date
Lesson Topic
Reproductive strategies
Lesson Outline
Outline and discuss K selected species. Stress population size is largely determined by the carrying capacity (K). Outline the common traits of the K selected species, and use diagrams.
Outline and discuss r selected species, r, and show how they are located at the opposite end of he spectrum from K selected.
List the traits and compare them to the K selected series.
Hand out a diagram which shows the progression from r to K

Lesson Topic
population growth models
Lesson Outline
Define and discuss both the exponential population growth model and the logistic population growth model.
Present the formula used to predict the future size of a population under ideal conditions.
Elicit properties of a J curve and examine them.
Elicit properties of the S curve and discuss them. This curve predicts the growth of populations subject to density dependent factors.
Define overshoot and die off. Examine both from a printed graph.
Discuss the effect of predation on the S growth curve, and explain why there are oscillations along the carrying capacity line

Lesson Topic
population ecology
Lesson Outline
Continue with basic characteristics of population ecology.Previous characteristics involve size, density, distribution and sex ratio.
Discuss the characteristic of age structure and how it affects in the short term, the population growth curve.
Outline density dependent factors, particularly food scarcity and its effect on plants and animal population size and density.
Examine and define carrying capacity (K) and how limited resources will affect the graph.

Session Date
Lesson Topic
population ecology
Lesson Outline
Outline and discuss the 5 basic characteristics of populations. These will include size, density, distribution, sex ratio, and age structure.
Define each characteristic, list and discuss factors within each one which will affect the population. Examine a series of diagrams which will aid in understanding each factor.
Discuss how the characteristics do not exist alone, but hypothesis regarding population growth are determined from an examination of many characteristics and how they intergrate and interact with each other.
Define, list, and discuss limiting factors, density dependent factors, and the carrying capacity of an ecosytem.

Discuss populations specifically. This will include:
Defining dynamic change in terms of birth, death, and movement.
Elicit a definition for population ecology.
Elicit factors involved in the study of population ecology.
Elicit and discuss why it is useful to identify and study the factors that influence population size.

evolution of niches
Lesson Outline
Discussion centering around how the evolution of species affects where they are able to live.
Outline and discuss the fundamental niche and the range of tolerance dealing with the abiotic conditions species can tolerate.
Display the graph showing the ideal conditions and that survival, growth, and reproductions will occur under these conditions.

Define the fundamental niche.
Examine the biotic factors which limit the locations within the niche.
Define and discuss the realized niche, the niche specialist, and the niche generalist specie.
