What's New
Version 6.10
Note: If you have a parameter file from an earlier version, and you are using behaviors that have been updated in version 6.10, load your file and save it. SORTIE-ND will automatically make any needed adjustments to your parameter file.
New in version 6.10:
- SORTIE now uses Java version 6. You'll need to download this version if you do not already have it.
- New allometry functions for crown shape - non-spatial density dependent calculates crown shape as a function of overall plot density, and NCI calculates crown shape as a function of local neighborhood composition.
- The Lagged post harvest growth behavior incorporates a lag period after a harvest during which tree growth is slowed.
- The Michaelis Menton with negative growth behavior uses a modified Michaelis Menton function that allows for negative height growth.
- The Michaelis Menton with photoinhibition behavior uses a modified Michaelis Menton function that allows additional control over the influence of light levels on growth.
- Michaelis Menton relative growth can now be used in height growth with the Relative growth - height only behavior.
- The Post harvest skidding mortality behavior provides an increase in tree mortality after harvesting due to skidding damage or other effects.
- The Masting non spatial disperse behavior behavior adds masting and inter year variation to basic seed rain.
- The Foliar chemistry behavior calculates various leaf chemical components as a function of DBH.
- You can now use height growth functions as your principle growth functions with the aid of the Allometric diameter growth behavior.
- The NCI growth and NCI Mortality behaviors are now more flexible - all of the modifying effects are now optional to allow you to use only the ones you need.
- The Quadrat-based GLI light behavior now has a flag to force calculation of GLI in every grid cell to allow this behavior to double as a light map creator even when trees to which the behavior is applied are not present.
- The values of a tree's crown radius and depth are now available as output variables.
- The tree map now displays DBH values at actual size at all scales.
- A new crown radius output display map shows crown radii at actual size, allowing visualization of crown overlaps.
- SORTIE now uses the GNU Scientific Library for mathematical calculations, thus expanding the range of possible function forms and probability distributions support
- The Functional response seed predation and Neighborhood seed predation behaviors can now be linked together so that the number of seed predators can determine the number of seeds eaten, and neighborhood can determine where seeds are eaten.
