Other claims from this paper (9)
- Observation In the Typha growth model, above- and below-ground biomass converged to a latitude-specific equilibrium regardless of the initial rhizome biomass.
- Observation Simulated Typha above-ground biomass decreased markedly at higher latitudes owing to a low photosynthetic rate.
- Observation Simulated Typha below-ground biomass increased with latitude up to 40 degrees due to decreasing metabolic losses.
- Observation Simulated Typha below-ground biomass then markedly decreased at latitudes above 40 degrees.
- Observation Simulated Typha above-ground biomass was enhanced with an increasing number of cohorts regardless of latitude.
- Observation More cohorts resulted in a larger simulated Typha below-ground biomass at low latitudes.
- Observation At high latitudes the largest simulated Typha below-ground biomass was provided by a smaller number of cohorts.
- Mechanism The difference in below-ground biomass between low and high latitudes is attributed to low production rates of late-season cohorts at high latitudes compared with consumption for shooting and establishing foliage.
- Recommendation The authors conclude the model can predict the potential growth of Typha over a wide range of latitudes and is useful for wetland management or wastewater treatment systems.
