Other claims from this paper (17)
- Intervention effect The hurricane caused the dominant species to become more dominant.
- Intervention effect The hurricane created low instantaneous tree mortality, 1% of stems.
- Intervention effect The hurricane reduced tree biomass at about -16 Mg/ha/yr.
- Intervention effect The hurricane reduced tree density.
- Intervention effect The hurricane did not reduce basal area.
- Intervention effect Five years after the hurricane, the forest had exceeded its prehurricane aboveground tree biomass, tree density and basal area.
- Observation Palms accounted for 76 percent of the aboveground tree biomass accumulation.
- Observation Before the hurricane the aboveground biomass accumulation rate was on the order of 3 Mg/ha/yr.
- Intervention effect Forest floor litter decreased to prehurricane levels (6.7 Mg/ha) within 5 yr, mostly due to disappearance of woody litter.
- Observation Thirteen tree species not represented in the canopy entered the forest by regeneration.
- Observation Two species suffered almost 20 percent/yr mortality over a 5-yr period after the storm.
- Intervention effect Delayed tree mortality was twice as high as instantaneous tree mortality after the storm.
- Association Delayed mortality affected dicotyledonous trees more than palms.
- Association Regeneration of dicotyledonous trees, palms and tree ferns was influenced by hydroperiod, light and space.
- Observation Redundancy Data Analysis showed the area near the river channel was the most favorable for plant regeneration.
- Association Palm regeneration was higher in locations with longer hydroperiods.
- Association Regeneration of dicotyledonous trees was higher in areas with low risk of flooding.
