New paper just out on the potential effects of climate change on reproduction in oysters. Led by Laura Falkenberg (now at the Chinese University of Hong Kong) and with CAS and Jon Havenhand from Tjarno Marine Lab helping, this work looked at how changed pH and salinity in predicted future climates affect sperm motility and how this might interfere with the breeding structure of wild (naturalised) populations of the oyster Crassostrea gigas. One of the main findings was that different populations (one recently established, the other much longer ago) differed in their responses, suggesting varying scope for selection and adaptation amongst populations.

Also to note – and without intentionally wanting to be controversial, we’ve stuck with the genus Crassostrea rather than the proposed Magallana because we agree with this paper here (rebutting the change), and because, well, we’ve always known the oyster as Crassostrea and it would just kind of do our heads in to now refer to it as Magallana. Moreover, putting actual taxonomic priority/convention reasons aside, the derivation of Crassostrea is from two Latin words (‘thick’ ‘oyster’) which is much less off putting as an oyster eater (i.e. doesn’t seem so bad to eat something that’s a bit dopey) than the rather more romantic naming after the global explorer Ferdinand Magellan.
