Desalination jeopardizes the future of Baltic Sea isopods
New publication from CeMEB member Pierre De Wit and collegues shows that future desalination will hamper the survival as well as the genetic diversity of Baltic isopods.
Highlights from the article:
- Climate change models predict that seawater salinity will drop in the Baltic sea
- We used a full-sib design to test experimentally the effects of hyposalinity on two populations of the isopod Idotea balthica
- We measured survival and loss of alleles due to hyposalinity
- Broods of Idotea exposed to hyposalinity had lower survival and lost several alleles.
- Our results show that future desalination will hamper the survival as well as the genetic diversity of Baltic I. balthica.
