Detection range of two acoustic transmitters in four reservoir habitat types using passive receivers

Table 2 ANOVA test results comparing the detection probability of V9 and V13 transmitters at four locations within Lake Sharpe, South Dakota, USA during daylight and nighttime hours

The percentage of detections registered relative the transmissions sent within a 15 min analysis bin were arcsine square root transformed and then compared within each location, for a given distance, for a give transmitter type, between the 2 time periods (day/night) using ANOVA. Data presented in the table include site location (Location), distance from transmitter to receiver (Distance). F-Statistic, and P value
