Master population dynamics in ecology with interactive visualizations. Learn exponential growth, logistic growth, predator-prey models, and b7r dynamics with step-by-step animations and real data examples.
Population dynamics in ecology is the branch of life sciences that studies the size and age composition of populations as dynamical systems, and the biological and ecological processes driving them. These models describe how populations change over time, including growth patterns, interactions, and ecological relationships.
In this interactive module, you'll explore fundamental population dynamics models including exponential growth, logistic growth, predator-prey relationships, and b7r models. Each model is demonstrated with visual examples and step-by-step animations to enhance understanding.

Understanding the distinctions between population dynamics and similar concepts
While population dynamics focuses on population size changes, population genetics studies genetic variation within populations and how allele frequencies change over time.
Ecology is the broader study of organism-environment interactions. Population dynamics is a subset that specifically models population changes, while ecology encompasses communities, ecosystems, and biogeochemical cycles.
Epidemiology studies disease spread in populations using similar mathematical models, but focuses on infection rates, recovery, and immunity rather than birth and death rates.

Practice problems with step-by-step solutions
Problem: A population of 500 bacteria doubles every hour. How many bacteria will there be after 5 hours?
Problem: A population has a carrying capacity of 2000 and a growth rate of 0.3. If the initial population is 200, what will the population be after 10 time units?
