28 Οκτ 2024 · Although life histories describe the way many characteristics of a population (such as their age structure) change over time in a general way, population ecologists make use of a variety of methods to model population dynamics mathematically.
18 Οκτ 2022 · The logistic model of population growth, while valid in many natural populations and a useful model, is a simplification of real-world population dynamics. Implicit in the model is that the carrying capacity of the environment does not change, which is not the case.
This part of the book provides an introduction to some simple mathematical models that describe the growth of populations, and Quattro Pro and Excel spreadsheet programs are used to simulate these populations.
This textbook provides an introduction to the biology and ecology of populations by emphasizing the roles of simple mathematical models in explaining the growth and behavior of populations. The author only assumes acquaintance with elementary calculus, and provides tutorial explanations where needed to develop mathematical concepts.
The Exponential Equation is a Standard Model Describing the Growth of a Single Population. The easiest way to capture the idea of a growing population is with a single celled organism,...
The two simplest models of population growth use deterministic equations (equations that do not account for random events) to describe the rate of change in the size of a population over time. The first of these models, exponential growth, describes populations that
1 Ιαν 2009 · In trying to understand patterns in empirical observations, a major challenge is to model the changes in the size distribution of a cohort with age. We introduce an individual-based growth model that is founded on the use of a stochastic class of processes called subordinators.
