Explore forest dynamics resulting from the interaction among bark beetle, spruce forest, temperature, drought severity, and tree diversity.

Bark Beetle Epidemic (Extended)

Explore forest dynamics resulting from the accelerated life span, overwinter survival rate, tree defense, beetle flight distance , and tree diversity.

Carrying Capacity

Explore carrying capacity in a hypothetic elk population. You may explore how carrying capacity is influenced by four types of factors: food, predator, another herbivore, and temperature.

Brine Shrimps in Great Salt Lake

In this model you will explore the bird and brine shrimp population dynamics in south arm of the Great Salt Lake resulting from the lake salinity, which is affected by stream inflow, north arm water inflow, and evaporation.
