Autecology: Tree vs' other plants

1
Autecology Tree vs. other plants

• What characteristics set trees apart from other
  plants?
• size
• longevity
• single axis
• profound secondary growth
• compartmentalization

2
Autecology Parts of the Tree

• Stem
• Leaves
• Roots
• Approach
• For each part, lets describe its purpose(s)
• For each part, lets describe the tissues known
  to support the purpose.
• How that purpose might be accomplished
• Identify abiotic and biotic factors potentially
  affecting this parts ability to meet one or more
  of these purposes. An examination of tradeoffs

Stem

• Functions
• Water nutrient transport
• Carbohydrate transport
• Water, nutrient carbohydrate storage
• Canopy support
• Potential conflicts
• Distance
• Weight
• Longevity
• Carbon costs

Stem tissues

• Bark
• Bark cambium
• Phloem
• Cambium
• Xylem
• Tracheids
• Fibers
• Vessels

Leaves

• Role of leaves
• Gas exchange
• Water loss
• Energy and heat exchange
• Storage
