    configured to play in two modes In the first mode each year the fish population is replenished to the same level regardless of how heavily it was exploited in the previous year While ecologically unrealistic in the long term this mode allows students to understand the exploitation dynamics that emerge when a resource is very abundant in relation to our ability to exploit that resource a situation that resembles early human exploitation of ecosystem services In the second mode the growth of the fish population is realistically dynamic the population in the current year is dictated by the fecundity of the species and the population surviving the previous year s fishing effort In this mode the fishery can crash and even go extinct Format pdf Primary or BEN resource type Laboratory exercise Secondary resource type Assignment activity non laboratory Discipline Specific Core Concepts Ecological Core Concepts Human impacts Human population growth and consumption Ecological Core Concepts Populations Population growth and regulation Life science discipline subject Ecology Keywords Population Growth Carrying Capacity Predator Prey Dynamics Fisheries Ecology Resource Management Multilevel Selection Sustainability Audience Undergraduate lower division 13 14 Grades 9 12 Intended End User Role Teacher Language English Educational Language English Pedagogical Use Description Students who complete these activities should be able to 1 Describe the effects of different individual levels of exploitation effort on the overall success of each individual 2 Differentiate between deterministic and stochastic influences on the outcome of experienced by each individual 3 Explain the different dynamics displayed by an resource limited system and one in which resources are delivered at a constant rate 4 Predict how resource limited systems will respond to unregulated exploitation in other words to predict a Tragedy of the Commons 5 Predict what level of exploitation will result in a crash of
