Data from: Ocean acidification alters sperm responses to egg-derived chemicals in a broadcast spawning mussel

The continued and unprecedented emissions of anthropogenic carbon dioxide (CO2) are causing progressive ocean acidification (OA). While deleterious effects of OA on biological systems are well documented in the growth of calcifying organisms, lesser studied impacts of OA include potential effects on gamete interactions that determine fertilisation, which are likely to influence the many marine species that spawn gametes externally. Here, we explore the effects of OA on the signalling mechanisms that enable sperm to track egg-derived chemicals (sperm chemotaxis). We focus on the mussel Mytilus galloprovincialis, where sperm chemotaxis enables eggs to selectively bias fertilisation in favour of genetically compatible males. Using a factorial experimental design, we test whether the experimental manipulation of seawater pH (comparing ambient conditions to predicted end-of-century scenarios) alters these patterns of differential sperm chemotaxis. While we find no evidence that patterns of male-female gametic compatibility are impacted by OA, we do find that individual males exhibit consistent variation in how their sperm perform in lowered pH levels. This finding of individual variability in the capacity of ejaculates to respond to chemoattractants under acidified conditions suggests that climate change will exert considerable pressure on male genotypes that can withstand an increasingly hostile fertilisation environment.

Figure 5. Principal component analysis scatter plot based on Fourier coefficients of the shell contours of Parreysia corrugata and Potomida semirugata: (а) PC1 vs PC2; and (b) PC2 vs PC4. The smaller circles indicate recent samples of the two species (see the legend). The stars indicate the paralectotypes of P. corrugata (the incongruent one is red), and the diamond indicates the lectotype of this species (NHMD 916309). The violet circle indicates the shell picture published by Chemnitz (1782, pl. 3, fig. 22a), and the yellow circle indicates the shell picture published by Müller (1779, pl. 3b, fig. 7). The coloured lines enclose 95% confidence ellipses. The PC1 axis describes 70.5%, the PC2 axis describes 8.3%, and PC4 describes 5.7% of the total variation. Synthetic outlines of the 'extreme' shell morphotypes are shown on four sides of the scatter plot. Information on shell lots and pictures used in the analyses is given in Supplementary data set 1.
