MODELLING A HUNTED MOOSE POPULATION IN NEW BRUNSWICK
To explore the role of hunting in population dynamics, a deterministic simulation model was built to mimic a real moose (Alces alces) population in a 2396 km2 area of southeastern New Brunswick. Data from moose population statistics in southeastern New Brunswick were used to initialize the models va...
