  2. Malthusian growth model - Wikipedia

    en.wikipedia.org/wiki/Malthusian_growth_model

    P 0 = P(0) is the initial population size, r = the population growth rate, which Ronald Fisher called the Malthusian parameter of population growth in The Genetical Theory of Natural Selection, [2] and Alfred J. Lotka called the intrinsic rate of increase, [3] [4] t = time. The model can also be written in the form of a differential equation:

  3. Population dynamics - Wikipedia

    en.wikipedia.org/wiki/Population_dynamics

    Evolutionary game theory was first developed by Ronald Fisher in his 1930 article The Genetic Theory of Natural Selection. [26] In 1973 John Maynard Smith formalised a central concept, the evolutionarily stable strategy. [27] Population dynamics have been used in several control theory applications. Evolutionary game theory can be used in ...

  4. Kolmogorov population model - Wikipedia

    en.wikipedia.org/wiki/Kolmogorov_population_model

    The Kolmogorov model addresses a limitation of the Volterra equations by imposing self-limiting growth in prey populations, preventing unrealistic exponential growth scenarios. It also provides a predictive model for the qualitative behavior of predator-prey systems without requiring explicit functional forms for the interaction terms. [5]

  5. Source–sink dynamics - Wikipedia

    en.wikipedia.org/wiki/Source–sink_dynamics

    Source–sink dynamics is a theoretical model used by ecologists to describe how variation in habitat quality may affect the population growth or decline of organisms.. Since quality is likely to vary among patches of habitat, it is important to consider how a low quality patch might affect a population.

    en.wikipedia.org/wiki/Development_economics

    Development economics is a branch of economics that deals with economic aspects of the development process in low- and middle- income countries. Its focus is not only on methods of promoting economic development, economic growth and structural change but also on improving the potential for the mass of the population, for example, through health, education and workplace conditions, whether ...

    theory. For example, David M. Cutler and colleagues (2003) investigate whether or not the increase in caloric intake over time could be seen as simply a rational response to the lowered prices of food, in particular packaged snack foods, which are tempting to consume because they are convenient and require little time to prepare.

  9. Demographic transition - Wikipedia

    en.wikipedia.org/wiki/Demographic_transition

    The theory is based on an interpretation of demographic history developed in 1930 by the American demographer Warren Thompson (1887–1973). [6] Adolphe Landry of France made similar observations on demographic patterns and population growth potential around 1934. [7]
