## Calculates population growth rate λ along element changes

The previous article introduced the sensitivity and elasticity to seasonal matrix model of imaginary annual plant. Both sensitivity and elasticity are partial derivatives. This means the values can only predict … Continue reading

## Sensitivity and Elasticity of seasonal matrix model

The previous article introduced the seasonal matrices and the population growth rate λ of imaginary annual plant. In this article, let’s try the sensitivity analysis of these matrices and the … Continue reading

## Stage abundances, eigenvector of population matrix

The previous article introduced the seasonal matrices and the population growth rate λ of imaginary annual plant. This article focuses on the meaning of the eigenvector at first, and then … Continue reading

## Periodic matrix model for annual plant demography

Let’s challenge to build a matrix population model of annual organisms and then calculate the population growth rate λ using R. Consider a simple life cycle of imaginary annual plants; … Continue reading
