Behavioral-Response Studies: Problems With Statistical Power
The behavioral-response study (BRS) is an experimental design used by field biologists to determine the function and/or behavioral effects of conspecific, heterospecific, or anthropogenic stimuli. Although this has been used for many years in studies of acoustic stimuli and whales, many of these studies have been limited by lack of true replication, otherwise known as “pseudoreplication” (Hurlbert 1984; Kroodsma 1989; Searcy 1989).
