Dynamic models play a vital role in addressing biological challenges, from disease control to predicting health events. This textbook, tailored for undergraduate biology students, introduces the principles of dynamic modeling. Authored by ecologist Stephen Ellner and mathematician John Guckenheimer, it offers insights into constructing and applying these models, bridging the gap between mathematics and biological sciences. This foundational resource aims to equip students with essential skills in computational biology, a field gaining prominence in academia.

This guide provides a comprehensive approach to modeling population dynamics using Integral Projection Models (IPM) based on observational data. Authored by a prominent research team, it includes R code for all computations, catering to ecologists, evolutionary biologists, and mathematical biologists interested in data-driven models for both animal and plant populations. While IPMs may appear complex due to their integral components, the book aims to simplify them, making them the preferred choice for populations characterized by size or other continuous traits. Through real examples of increasing complexity, it illustrates how the life cycle of the study organism informs the appropriate statistical analysis, leading directly to the IPM. The text covers a variety of model types and analyses, including model construction, computational methods, and foundational theory, with more technical details provided in Boxes and Appendices. Readers can access self-contained R code on GitHub to replicate all figures and calculations presented. The authors are established experts in their fields, with affiliations to Cornell University and The University of Sheffield.
