Populations of living organisms are able to grow
exponentially in number.

Principle of growth regulation
Exponential population growth occurs only
temporarily in nature. The mean rate of
population increase is regulated.
Principle of robust coexistence
Populations may coexist if their growth
regulation differs. The larger the difference in
their regulation the more robust their
coexistence is.
9
Principle of inherited variations
Errors always occur when the genetic material is
replicated. Repeated emergence of inherited
variation within populations is unavoidable.

Principle of natural selection
If there is difference between the population
growth rates of individuals with different
heritable traits, the one with the higher growth
rate exponentially outgrows the one with the
smaller growth rate.
Principle of allocation
Life-history traits increasing the population
growth rate (fitness) are in trade-off, that is,
they can increase at the expense of each other
only.

Principle of robust coexistence
Populations sharing regulating factors may
coexist if their growth regulation differs. The
larger the difference is in their regulation the
more robust their coexistence is.

Outlook

• Ecology
• The science of the struggle for existence.
• Haeckel, 1866 Cooper, 2003
• Regulation of population growth is a must.
• A general theory is not only possible but it is
  also very useful.
• Integration, operationality, disciplinarity

Linking research and education

• Effective education requires clarity and a
  coherent presentation.
• Clarity and coherent presentation improves
  research.
