Title: Plant Competition


1
Plant Competition
2
Today we will
  • Understand differences between intraspecific
    and interspecific competition
  • Measure plant competition in Sanford Woodlot
  • Apply our knowledge of correlations to
    understanding competition dynamics

3
Competition
  • Interspecific (between species)
  • Intraspecific (within species)

4
Competition
  • Interspecific (between species)
  • Intraspecific (within species)

5
Competition
  • Direct
  • Indirect
  • Effects of one species impact another species
    indirectly
  • Apparent Competition
  • Exploitative Competition

Animals physical combat Plants release of toxins
6
Apparent Competition (Indirect)
  • Abundance of one species increases likelihood of
    consumption of other species

7
Exploitative Competition (Indirect)
  • Individuals use same limiting resource (most
    common type of competition)

8
Why is it important to understand competition
dynamics and outcomes?
9
What are the trade-offs between conducting
controlled, manipulative experiments and
observational studies?
10
Todays Activity Measuring Competition
  • Read over page 65

11
Todays Activity Measuring Competition
  • We will measure
  • Intraspecific competition in beech trees
  • Interspecific competition between beech trees and
    other trees (collectively)

12
Todays Activity Measuring Competition
  • Methods What will you do?
  • Along transect, find focal beech tree, measure
    DBH
  • From that tree measure DBH of nearest beech and
    nearest other tree
  • Continue at every 6 meters (6 focal trees total)

13
Todays Activity Measuring Competition
  • Each team needs
  • One 30-meter tape
  • Coursepack
  • Writing utensils

14
Data Analysis Results
  • Calculate mean, standard deviation, and
    correlation coefficient using Excel sheet (ANGEL)
  • Graph results
  • Answer questions on page 66
  • Class discussion of results
  • Quiz
