Figure 3

Multidimensional scaling plots in two dimensions using Bray-Curtis similarity matrices. MDS plots using Bray-Curtis similarity matrices performed on logarithmically transformed spectral frequency data produced using Discrete Fourier Transform analysis of (i) negative angle (ii) positive angle (iii) centre of mass - rho and (iv) centre of mass - theta, frame-to-frame parameters for (a) Danio rerio, (b) Xenopus laevis and (c) Radix balthica under different environmental conditions and at different developmental stages. Bubble size represents the amount of tail flicks of Danio rerio and Xenopus laevis, the number of rotations of Radix balthica at stages E3, E4 and E6, and the number of complete gliding along the circumference of the egg capsule on stages E9 and E11.
