Hurricane Damage to a Hawaiian Forest: Nutrient Supply Rate Affects Resistance and Resilience

Darrell A. Herbert; James H. Fownes; Peter M. Vitousek Ecology 1999. doi:10.2307/177027

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.
Association Leaf area index reductions were greatest in P-amended treatments.
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 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.

Other claims from this paper (7)

Intervention effect Pre-drought reduced chilling-induced leaf necrosis.
Intervention effect Droughted plants had higher leaf water status after chilling.
Mechanism Drought-induced stomatal closure was proposed to explain higher water status.
Intervention effect Chilling reduced carbon dioxide exchange similarly in droughted and untreated seedlings.
Intervention effect During recovery, droughted seedlings had higher carbon dioxide fixation.
Mechanism The authors inferred that stomatal limitation did not cause chilling-induced CER inhibition.
Intervention effect Droughted maize had better photosynthetic water-use efficiency.
