สรุป	Acoustic telemetry is a remote tracking method in which small electronic transmitters attached to or implanted in animals emit unique acoustic signals detectable by underwater or terrestrial receiver networks, enabling real-time monitoring of animal movements, positions, and behavior over extended distances and times. Pioneered in fisheries research in the 1960s, acoustic telemetry is now standard for studying movement ecology, migration timing, and habitat use in aquatic and increasingly terrestrial systems.	Focal Animal Sampling (FAS) is a systematic observational method in which an observer focuses on one individual animal at a time, recording its behavior continuously or at regular intervals for a fixed period. Introduced by Jeanne Altmann in 1974, FAS provides detailed, quantitative ethograms of individual behavior, making it essential for studying animal behavioral ecology, welfare, and responses to environmental changes.	Scan Sampling (also called instantaneous sampling) is a behavioral observation method in which an observer records the state of all group members simultaneously at regular time intervals. Introduced alongside focal animal sampling by Jeanne Altmann in 1974, scan sampling is efficient for quantifying activity budgets and group-level behavioral patterns in multiple animals without the labor of focal observation.
