Exploring the conditions of permanent coexistence, rather than gradual disappearance of disadvantaged competitors. ​Z506 p32-35 System Zoo 3 by Hartmut Bossel.

A collaborative class project with each participant creating an animal/plant sub-model​ to explore the greater population/community dynamics of the Yellowstone ecosystem.

Influence of migration on the number of working-age population.

This is a basic population estimator. Default values approximate recent data for the United States, except for the birth rate.

Primer ensayo de simulación, modelo sencillo de población de zorros y conejos. Mi modelo consiste en un modelo sencillo de la población de Zorros y conejos, donde la población de conejos se ve afectada  por la muerte de conejos, la cual es el producto  de la  tasa de muerte de los conejos  multiplicado por la población de conejos, más  la población de zorros  multiplicada  por los conejos que se come cada zorro. También se tiene en cuenta que si no hay conejos suficientes  aumenta la  tasa de mortalidad de zorros.

Initial attempt to reduce confusion about risk and odds ratios.

Koala Population Case Study

Sian Phillips

A simple simulation used to observe the California Yellowtail population in San Diego

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

This in-depth concept map portrays the factors influencing koala births and deaths in SEQ. It also shows that the eucalyptus tree population in SEQ is vital for the survival of the koala.

Modelagem do estado psicológico de uma população. Inicialmente, todos os indivíduos estão no estado "Calmo". Com o passar do tempo e com as interações mútuas, há o surgimento e progressivo aumento do total de indivíduos com raiva (estado "Raivoso"). Deste estado e, com o passar do tempo, os indivíduos podem evoluir mentalmente e atingirem o estado "Indiferente", nos quais eles se tornam indiferentes à qualquer interação. Outra possibilidade é o indivíduo se enriquecer e, assim, atingir a felicidade (estado "Feliz").

Influence of migration on the number of working-age population.

Influence of migration on the number of working-age population.

The SEQ Koala Population over recent years has suffered due to a number of factors; habitat loss, predators, natural disasters, health issues and road fatalities to name a few.  All the while conservation efforts are being made to aid the population growth of  the national icon.

This insight draws together these contributing factors into a single population model (simulation).  This model begins with the known 2006 population and it projected based on current decline rates.  Accuracy is limited, however the downward trend is clearly evident.

FORCED GROWTH GROWTH GOES INTO TURBULENT CHAOTIC DESTRUCTION 
 BEWARE pushing increased growth blows the system!
(governments are trying to push growth on already unstable systems !)

The existing global capitalistic growth paradigm is totally flawed

The chaotic turbulence is the result of the concept and flawed strategy of infinite bigness this has been the destructive influence on all empires and now shown up by Feigenbaum numbers and Dunbar numbers for neural netwoirks

See Guy Lakeman Bubble Theory for more details on keeping systems within finite limited size working capacity containers (villages communities)

Adding change over time to relative risk, odds ratio and population attributable fraction epidemiology concepts see wikipedia and examples .
