Presentation Transcript

  1. Bio 161 Ecology and Evolution Population Ecology (2): Life history strategies:Maximize reproductive value.

  2. Population Biology:

  3. Life history of the individual: Birth Energy gathering (feeding) Growth Dispersal Reproduction Rest / reorganization Death Unique life history strategies of species.

  4. Life History Patterns: Monarch butterfly.

  5. Common goal of different life history strategies:

  6. RV = CRV + RRV. Example: Mortality in function of number of fecundity (clutch size and number of clutches) in birds.

  7. Correlation between annual fecundity and annual mortality in birds Across bird species.

  8. RV = CR + RRV. Example: Clutch size of the following year in function of the current clutch size (when larger of smaller than average) of goldfinch.

  9. RV = CR + RRV. Example: Nestling weight in function of the clutch size of chickadee.

  10. RV = CR + RRV. Lack and Optimum clutch size in birds.

  11. RV = CR + RRV. Example: Optimal number and size of lizard babies.

  12. Size of lizard babies after experimental (surgical) manipulations of developing eggs. Developing eggs removed Control Yolk removed

  13. Life history strategies:

  14. Semelparityvsiteroparity

  15. r/K –selected life history strategies.

  16. Bio 161 Ecology and Evolution Population Ecology (3): Demography (Describing population dynamics).

  17. Population demography:

  18. Age-structure pyramids.

  19. Age-structure pyramids: Predicting the health and future of a population.

  20. Effect of China’s “one-child” policy on population structure. (Science September 17 2010, vol. 329 p1459.)
