Stenophagous preadtors
Selective of prey - herbivores - koala bear only eats eucalyptus leaves
Herbivory
Herbivory of roots and leaves reduces plant growth and seed production
Strategies to avoid herbivory
- Fast growth to reproduce before being eaten (r strategy)
- Invest in more root and soot biomas (perennial seeds)
- Chemical and physical protection to reduce palatability
Landscape of fear
Elks hide in forest to avoid being eaten when grazing in the meadow. This reduces herbivory amongst elk allowing vegetation to r cover
Dispersal
Movement of organisms away from origin
Passive dispersal
Wind or water
Seed dispersal type
- Autochory (ejection from parent plant)
- Semachory (swaying motion by wind)
- Anemochory (wind)
- Hydrochory (water)
- Zoochory (body or digestion)
- Hemerochory (human activity)
Phalanx strategy
Tightly packed front of advancing ramets
Guerilla strategy
Infiltrate their surrounding by widely space ramets, defence against grazing pressure, facilitation of other species
Succession
Changes in physical and biological conditions of an ecosystem (usually following disturbance)
Primary succession
Previously lifeless environment is colonised
Secondary succession
Ecosystem recovers from a disturbance
