Table 3:

Results of individual F-tests for parallelism for baleen extract of eight mysticete whales in eight enzyme immunoassays, comparing slopes of the linear portions of the standard curve and the serial dilution of baleen extract for each species. Variable degrees of freedom are due to some dilutions having undetectable hormone content for some species. All P values are > 0.00625, the Bonferroni-corrected alpha value for each hormone. ‘Right’ = North Atlantic right whale; T3 = tri-iodothyronine; T4 = thyroxine
