TetrasPool Assumptions TetrasPool is a model based on the life cycle of tetraonids birds. Environmental stochasticity affects the proportion of reproductive females, juvenile and adult survival rates, as well as fecundity. Demographic stochasticity influences individual reproductive status, survival status and fecundity.
Density dependence is of ceiling type.
Dispersal is either random or directional, and the probability to reach a target patch depends on distance. Spatial correlation are distance independent. Each population has a precise spatial location. Populations are censued after hatching and before dispersal events. A map with the position of all population.
