This week we will be discussing an aspect of organismal biology that plays into it's population ecology intimately - life history. Please watch this video and respond to the discussion points below.
What is life history? What is fecundity? Compare and contrast the life histories of the three organisms discussed in this video. Compare and contrast semelparity and iteroparity. What is meant by 'fitness'? We talk about the combinations of life cycle variables like fecundity, age of reproduction, and life span as 'life history strategies'. Discuss how natural selection may have lead to alternative life history strategies. How do you think an organism's life history might be related to its population ecology? (Hint, think growth rates.) How do you think life history variables relate to our projects on bats of Belize and small mammals of Madagascar?

1. Life History is the series of changes undergone by an organism during its lifetime. Life History also focuses on the characteristics and aspects of organisms such as their reproductive development and behavior, their life span, parental dependence, etc.
