Lefkovitchmodeller
The Lefkovitch model, also known as the Lefkovitch matrix, is a method for analyzing the age- or stage-structured population dynamics of a species. Developed by Paul Lefkovitch in 1965, it extends the basic Leslie matrix model by allowing individuals to transition between different stages or classes that are not necessarily related to age. This is particularly useful for organisms where development is highly variable or where distinct life stages, such as larval, pupal, and adult, are more relevant than chronological age.
The Lefkovitch matrix represents the population as a vector of individuals in different classes. The matrix
By multiplying the population vector by the Lefkovitch matrix, one can project the population structure and
