| Summary: | 1. Radio-tag signals from fixed-position antennas are most often used to indicate presence/absence of individuals, or to estimate individual activity levels from signal strength variation within an antenna’s detection zone. The potential of such systems to provide more precise information on tag location and movement has not been explored in great detail in an ecological setting. 2. By reversing the roles that transmitters and receivers play in localization methods common to the telecommunications industry, we present a new telemetric tool for accurately estimating the location of tagged individuals from received signal strength values. The methods used to characterize the study area in terms of received signal strength are described, as is the random forest model used for localization. The resulting method is then validated using test data before being applied to true data collected from tagged individuals in the study site. 3. Application of the localization method to test data withheld from the learning ... : BoquetData_River_Radio_MapThis radio map of the Willsboro rapids was used as learning data in a random forest location fingerprinting exercise to identify the progress of migrating Atlantic salmon in the Boquet River.BoquetData_River_Telemetry_DataThis radio telemetry data was collected from 24 tagged Atlantic salmon as they migrated up the Boquet River through the Willsboro rapids. Sites correspond to separate antenna & receivers throughout the study reach, while the Code corresponds to separate fish. ... |
