Predator-prey dynamics is a subfield of ecology that studies the interactions between predator and prey populations in ecological systems. This research area focuses on understanding how predators and prey influence each other's populations, behaviors, and evolution. Scientists investigate the predator-prey relationship through various mathematical models, field studies, and laboratory experiments to uncover the underlying mechanisms that drive these interactions. Key concepts in predator-prey dynamics include predation rates, prey defenses, population cycles, and coevolutionary relationships between predators and their prey. By studying predator-prey dynamics, ecologists gain insights into the stability and functioning of ecosystems and the impacts of human activities on natural communities.
