C-S-R Strategy Flashcards
Stress-tolerators: survive even when an important
Resource for growth may be lacking.
Stress-tolerators: adapted to harsh environments, may be exposed to
Extremes of temperature, wind and toxic conditions,
Stress-tolerators: inhibit environments with
Poor nutrient supplies.
Stress-tolerators: use resources in short supply efficiently, they have a
Lower demand for resources than competitors do and are unable to compete for resources effectively.
Stress-tolerators: have a small
Growth rate, stature and low turnover of leaves and roots.
Stress-tolerators: delay reproduction until
Well established.
Stress-tolerators: Cowslip: (4)
Heights of up to 0.2m.
Flowers in second or third season.
Grows in old, unfertilized grasslands.
Slow growing, but long lived - retains existing tissues, little growth is added each year.
Ruderal: niche is
Environments where disturbances are high, including the removal of all surface vegetation.
Ruderal: Don’t make efficient use of
Resources, unlike ST.
Ruderal: Are short lived,
They only flower once and devote resources to reproduction as soon as possible.
Ruderal: Don’t maximise resource
Capture, unlike competitors.
Ruderal: Field Poppy: (2)
Seeds can lie dormant for many years and activate when brought to the surface.
Found in unpredictable environments where rainfall varies.
Competitors:
Survive by outgrowing their neighbours.
Competitors: need rapid, tall upright growth to
Shade neighbours and inhibit their growth.
Competitors: For rapid growth, a good supply of
Nutrients is needed.
