Population ecology is a branch of ecology that focuses on the study of the dynamics of populations of organisms and how they interact with their environments. This field of research examines factors such as population size, density, distribution, growth rates, and interactions with other species. Researchers in population ecology study how populations change over time in response to factors such as competition for resources, predation, disease, and environmental changes. They also investigate how populations adapt to their environments and how human activities impact population dynamics. Through population ecology research, scientists seek to understand the complex relationships between organisms and their environments, and how these relationships influence the structure and functioning of ecosystems. This knowledge is crucial for conservation efforts, resource management, and understanding the impacts of climate change on biodiversity.
