The role of ectoparasites in ecology involves their interactions with host organisms, often impacting health, behavior, and population dynamics. Ectoparasites, such as ticks and fleas, feed on the external surfaces of hosts, which can lead to various health issues, including disease transmission and weakened immunity. These interactions can influence host behaviors, affecting social structures and breeding success. Moreover, ectoparasite populations can serve as ecological indicators, reflecting environmental changes and host health. Understanding these dynamics is essential for managing wildlife populations and preventing the spread of diseases.
