development and calibration of a model for the simulation of the beehive", the model beehive", the model ApiPop, developed within the modelling environment

ApiPop, developed within the modelling environment SEMoLASEMoLA (Simple, Easy to use, (Simple, Easy to use, Modeling

The model is formed by seven modules developed by five working units: queen nits: queen behaviour (

behaviour (AP_queenAP_queen) based on ) based on BeePopBeePop model (DeGrandimodel (DeGrandi--HoffmanHoffman et al., 1989), colony et al., 1989), colony dynamics (

dynamics (AP_colonyAP_colony), available cells (), available cells (AP_cellsAP_cells), hive management (), hive management (AP_beekeepingAP_beekeeping), ), vegetation (

vegetation (AP_vegetationAP_vegetation), foraging activity (), foraging activity (AP_foragingAP_foraging), honey and pollen ), honey and pollen production (
