Other claims from this paper (19)
- Observation Four of five modeled woody species decline with frequent burning.
- Observation Four of five modeled woody species increase with infrequent burning.
- Observation The four fire-sensitive species require fire intervals of 2–9 years for long-term persistence.
- Observation The fifth shrub species was virtually unaffected by burning.
- Association Across eight species, population growth under annual burning was negatively related to growth without burning.
- Observation Herbaceous species performed best under high fire frequency.
- Observation Fire stimulates vegetative propagation in all three species that produce root suckers.
- Observation Fire reduces sexual reproduction in the three root-suckering species.
- Observation Vegetative propagation contributes more than sexual reproduction to population maintenance of the three species.
- Observation Vegetative propagation is relatively more important under frequent burning.
- Observation Stasis and progression contributed more to population growth than either reproductive mode.
- Observation Stasis made the largest contribution to population growth.
- Observation The fire effect on sexual reproduction contributed little to the population-growth effect, particularly in clonal species.
- Observation Fire-induced mortality generally had little effect on population growth.
- Observation Miconia albicans seedlings were exceptionally sensitive to fire.
- Observation The negative effect of fire on individual size was the greatest contributor to reduced population growth.
- Observation The fire effect on individual size was greater in the two trees than in shrubs.
- Association Growth form was the primary determinant of fire response, while vegetative reproduction mattered less.
- Observation Current fire regimes are predicted to reduce woody plant density and favor smaller clonal forms.
