Principal-component analysis of dehydrated P. vanderplanki. (A and B) FTIR spectra were decomposed into two components: P1 and P2 in slowly dehydrated larvae (A) and P1′ and P2′ in quickly dehydrated larvae (B). Shown is a region between 3,800 and 3,000 cm−1 (Fig. 3A). P1′ is likely to be a noise. (C and D) Temperature-dependent change of the score value for each principal component.
