Koala Population Case Study

Sian Phillips

• Between 1999 and 2006 Koala population had dropped 26% in Queensland. 
• By 2008 it was estimated there were around 2300 Koalas with more than a 50% population loss in less than 3 years. 
• Main threats for Koala survival are a loss of habitat, vehicular trauma, dog attacks, urbanisation, disease and climate change.

Shows the ecological impact of population.

This is a basic model for use with our lab section.  The full BIDE options.

Adapted from Hartmut Bossel's "System Zoo 3 Simulation Models, Economy, Society, Development."

​Population model where the population is summarized in four age groups (children, parents, older people, old people). Used as a base population model for dealing with issues such as employment, care for the elderly, pensions dynamics, etc.

Simulation of how tiger population and anti poaching efforts effect the black market value of tiger organs.

This is a basic BIDE (birth, immigration, death, emigration) model.  Not all parts are implemented, however Birth and Death are.

This model is under construction, not at all ready, don't use it for any purposes (my suggestion ☺) yet.

A quick population rate model to help get acquainted to modular designs.

This model incorporates several options in examining fisheries dynamics and fisheries employment. The two most important aspects are the choice between I)managing based on setting fixed quota versus setting fixed effort , and ii) using the 'scientific advice' for quota setting  versus allowing 'political influence' on quota setting (the assumption here is that you have good estimates of recruitment and stock assessments that form the basis of 'scientific advice' and then 'political influnce' that desires increased quota beyond the scientific advice).

Von Foerster's doomsday equation says that population growth is hyperbolic because the exponent itself (the growth rate) is a function of population.
