Welcome to the
HexSim is a free, versatile, multi-species, life history simulator ideal for building models of animal and plant population viability, interactions, and responses to disturbance. HexSim models are spatially-explicit and individual-based, and HexSim individuals can be assigned dynamic life history traits. HexSim also includes a full genetics sub-model, making it a true eco-evo simulator.
HexSim is not licensed, and is available free of charge.
Example Uses of HexSim
Develop PVA models
Impose stressor interactions
Evaluate landscape connectivity
Conduct source-sink analyses
Model competition and predation
Explore landscape genetics
Simulate disease dynamics
