The primary focus of population ecology is to understand the dynamics of species populations, including their size, structure, and growth trends. It examines how various factors such as resource availability, predation, and competition influence population behaviors and interactions. Population ecology also addresses the relationships between populations and their environments, aiming to predict changes in population sizes over time. By studying these dynamics, researchers can inform conservation efforts, manage wildlife populations, and assess the impacts of environmental changes. Ultimately, population ecology contributes to a richer understanding of ecosystem stability.
