Population dynamics is the study of how populations of organisms change over time. This includes factors such as birth rates, death rates, immigration, and emigration. Understanding these changes helps scientists predict how populations will grow or decline, which is important for managing wildlife and natural resources. In ecology, population dynamics can be influenced by environmental factors like food availability, habitat space, and climate. Models are often used to simulate these dynamics, helping researchers understand the interactions between different species and their ecosystems. This knowledge is crucial for conservation efforts and maintaining biodiversity in areas affected by human activity.
