The Leslie matrix is used in ecology to model the changes in a population of organisms over a period of time. In a Leslie model, the population is divided into groups based on age classes.

The Leslie Matrix This matrix is a special matrix used in demography and population biology It is referred to as a Leslie Matrix after its inventor Sir Paul Leslie (Leslie 1945, 1948) A Leslie Matrix contains: •age-specific fertilities along the first row •age-specific survival probabilities along the subdiagonal •Zeros everywhere else

Aug 19, 2002 · A. Leslie Matrix or Population Projection Matrix (denoted A) Contains age-specific fecundity and survival rates. For example, with 3 age classes (ages 0-2, females only) the Leslie matrix would take the form:

Leslie Matrix = Population Projection Matrix Contains age-specific fecundity and survival rates. For example, with 3 age classes (ages 0-2, females only) the Leslie matrix would take the form: Fx = age-specific fecundity (modified to take survival between census periods into account)

The Leslie Matrix (also called the Leslie Model) is one of the best known ways to describe the growth of populations (and their projected age distribution), in which a population is closed to migration and where only one sex, usually the female, is considered.

In 1945 the British ecologist P.H. Leslie analyzed a matrix model for an age-structured population of rodents, thus adapting Lotka’s work to a discrete-time framework. He emphasized that the growth rate corresponds to an eigenvalue and the “stable” age structure to an eigenvector.

This type of matrix population model that takes into account births and survival rates of each class over time is known as the Leslie matrix model. How does the population of locusts change over six years if there are initally only 50 adults and no eggs or hoppers?

Feb 4, 2024 · The Leslie model considers individuals of one sex in a population which is closed to migration. The maximum life span is $k$ time units, and an individual is said to be in the $i$th age group if its exact age falls in the interval $[ i - 1 , i )$, for some $1 \leq i \leq k$.
