  1. HOW TO ACCESS NOTES • 2 Ways: • Go to: http://www.sfu.ca/biology/courses/bisc407/ • OR • Biology homepage, Biology Dept., Undergrad link, Bisc 407 link

  2. SOME INFO • Textbook: The following textbook is recommended but not required: A Primer of Population Ecology, N. Gotelli • In addition, copies of relevant original articles will be available via our website. • Tutorial outline Each week, a portion of the tutorial will be allotted to discussion of and questions pertaining to the current lecture.

  3. SOME INFO:II • Article reports Each student will prepare 2 written reports on current journal articles of his/her choice. Reports should be less than 3 pages in length and typed if possible. Reports will be graded on (i) demonstration of understanding of the article, and (ii) quality of the written report. The following journals are suggested sources for articles:Ecology, Ecology Letters, American Naturalist, J. Animal Ecology J. Theoretical Biology, Oecologia, Theoretical Population Biology, Oikos, etc.

  4. SOME INFO:III Assignments Each student will be provided several problem sets during the semester. The sets are meant to provide "hands-on" experience with quantitative analysis. Completed assignments should contain all of the analysis. Final solutions alone will be judged insufficient. Late submissions will be docked 5% per day.

  5. SOME INFO:IV Mark distribution Midterm (Oct. 21) 25%
Final Exam (Dec. 12) 45% 
Tutorial 10%
Assignments 15%
Reports 5% Tutorials will be graded on overall contribution to tutorial discussion.

  6. GRADE SCHEME

  7. POPULATIONS • All individuals in a given area • Group of interbreeding individuals at a given locality • (Species - groups of actual or potential interbreeding populations)

  8. POPULATIONS: WORKING DEFINITIONS • Absolute: # individuals/ unit area • Intensity: # individuals/ unit habitat • Basic: Intermediate of absolute and intensity e.g. #/cm2 leaf surface

  9. POPULATION TABLE

  10. POPULATION DYNAMICS Generation

  11. POPULATION CURVES • Total Population Curve: total number of individuals vs. time • Partial Population Curve: # of individuals of each life stage vs. time

  12. SIMULATION 1 • Three stages: egg(3), larva(3), adult(1) • All individuals live full life • Recruit eggs every day via random draw (0,20) • Calculate number of insect-days

  13. FULL LIFE EXPECTANCY INSECT-DAYS= 952 PREDICT 952/7 = 136 ADULTS OBSERVE 136 ADULTS

  14. SIMULATION 2 • Three stages: egg(3), larva(3), adult(1) • All individuals live full life • Recruit eggs every day via random draw (0,20) • Crisis with probability of 0.15/day • Each crisis kills 0.2 larvae • Calculate number of insect-days

  15. INCLUDES CRISIS INSECT- DAYS = 633 PREDICT 633/7 = 91 ADULTS OBSERVE 74 ADULTS

  16. POPULATION DYNAMICS G1
