added species-parameter "sapReferenceFactor" (for calculation of f_env,yr for sapling growth). |

changed label in regeneration debug output,
added minimum height of 4m as requirement for seed production. |

sapling growth now in a basic working state. started to implement recruitment. One bug with the "maximum-establishment-height-grid" known.
added also visualization of regeneration layer. Once I have time, I should restructure the drawing/visualization code as it gets quirky (and a paper-concept is available...) |

put Establishment parameters into database (total of 8 params).
new version 0.3 -- yeah!
just for the records the SQL for regeneration and Establishment:
-- add columns for regeneration
alter table species add maturityYears integer;
alter table species add seedYearInterval integer;
alter table species add nonSeedYearFraction real;
alter table species add fecundity_m2 real;
alter table species add seedKernel_as1 real;
alter table species add seedKernel_as2 real;
alter table species add seedKernel_ks0 real;
-- default values regeneration
update species
set maturityYears=30,seedYearInterval=5, nonSeedYearFraction=0.25, fecundity_m2=100, seedKernel_as1=100, seedKernel_as2=0, seedKernel_ks0=0;
-- add columns for establishment

added database species parameters for seed dispersal, fixed a bug with random generator in StandLoader, change maturity criterion for seed production to age instead of height. |

/src/ |
made the calculate() and execute() function of Expression const (using a trick), so there is no more need for un-const functions which should be const (e.g. in Species). |
|

/src/core/ |
removed the QMutex and the QMutexLocker for serializing the execution of expression evaluations. This is no longer necessary, because Expression::calculate() now is reentrant.
The performance effect of this change is awesome: the time used to grow individual trees drops by ca. 40% (the total runtime is maybe 5-10% faster) (tested with iLandSpeed.xml -> 2x2km) |

seed dispersal:
* defining synchronized seed years for each species
* use different seed kernels depending on seed year state
* create two kernels for each species (1x seed year, 1 x non-seed-year)
* newYear() function also for each Species |
|

5209d 22h |

/src/ |
a rather large update mainly in course of the implementation of seed dispersal.
* integrating the seed dispersal within the model logic
(new function e.g. SpeciesSet::newYear() or SpeciesSet::regeneration()).
* SeedDispersal: implementation of the Seed-Kernel a la TreeMig (see the R-Script on dispersal by Rupert)
Additionally:
new functions (sum(), multiply() for the Grid-template. |

remodified the age calculation. Now the age is estimated based on the current height relative to h_max. The aging-calculation itself is no longer changed by that. |

/src/ |
integrating seed dispersal into the model
moved global constants for grid sizes into globalsettings.h |

little update to tree age issues |
|

/src/core/ |
appropriate handling of tree age during initialization.
if no age is provided in the input file only the tree height is used for the aging calculation. The tree "age" in that case reflects only the number of years since initialization. |

added explicit fine root compartment in tree. Changed partitioning, the calculation of the stress index, follow-up change in several outputs. |
