Other claims from this paper (18)
- Observation Leaf area index was reduced by 3% to 59% after Hurricane Iniki.
- Association Leaf area index reductions after the hurricane were correlated with prehurricane LAI.
- Observation Leaf area index recovered to near prehurricane levels within 9 months after the hurricane.
- Association Rates of leaf area index recovery were unaffected by treatment.
- Observation Fine root mortality after the hurricane ranged from 35% to 48%.
- Observation Fine root mortality recovered within 2 years after the hurricane.
- Observation Stem damage from the hurricane was largely branch removal.
- Association Large trees were damaged more frequently than small trees.
- Observation Fine litterfall caused by the storm was 1.4 times the annual input.
- Association Nutrient transfers to the forest floor after the hurricane approximated those of a typical year.
- Intervention effect In +P treatments, stem diameter increment and ANPP declined after the hurricane but returned to prehurricane values 2 years later.
- Intervention effect In -P treatments, stem diameter increment and ANPP remained low after the hurricane.
- Association Rates of recovery of stem growth and ANPP to prehurricane levels were greater in +P treatments.
- Association ANPP per unit leaf area was much greater in +P treatments.
- Association Ecosystem resistance and resilience are inversely related.
- Association Resistance decreases as supply rates of limiting resources increase.
- Association Resilience increases as supply rates of limiting resources increase.
- Recommendation Structural and functional components of resistance and resilience should be considered separately.
