Learning outcomes
|
The aim of the course is to give students the fundamentals of a modern population ekology theory, emphasising demohraphy and population dynamics. Throughout exercises, students acquire the skill to estimate important population parameters using special software packages.
Knowledge Explain the principles of population growth and dynamics Describe the effects of population structure on population growth rate Identify interactions regulating population size
