Long-term and trans-life-cycle effects of exposure to ocean acidification in the green sea urchin Strongylocentrotus droebachiensis

Trans-life cycle impacts of ocean acidification on the green sea urchin Strongylocentrotus droebachiensis Doctoral thesis

Genomic Characterization of the Evolutionary Potential of the Sea Urchin Strongylocentrotus droebachiensis Facing Ocean Acidification

Ocean acidification (OA) is increasing due to anthropogenic CO2 emissions and poses a threat to marine species and communities worldwide. To better project the effects of acidification on organisms' health and persistence, an understanding is needed of the 1) mechanisms underlying developmental and physiological tolerance and 2) potential populations have for rapid evolutionary adaptation. This...

Acidification reduced growth rate but not swimming speed of larval sea urchins

Swimming behaviors of planktonic larvae impact dispersal and population dynamics of many benthic marine invertebrates. This key ecological function is modulated by larval development dynamics, biomechanics of the resulting morphology, and behavioral choices. Studies on ocean acidification effects on larval stages have yet to address this important interaction between development and swimming un...

Effect of ocean acidification on growth, gonad development and physiology of the sea urchin Hemicentrotus pulcherrimus

Ocean acidification, due to diffusive uptake of atmospheric CO2, has potentially profound ramifications for the entire marine ecosystem. Scientific knowledge on the biological impacts of ocean acidification is rapidly accumulating; however, data are still scarce on whether and how ocean acidification affects the reproductive system of marine organisms. We evaluated the long-term (9 mo) effects ...

Genetic diversity of the NE Atlantic sea urchin Strongylocentrotus droebachiensis unveils chaotic genetic patchiness possibly linked to local selective pressure

We compared the genetic differentiation in the green sea urchin Strongylocentrotus droebachiensis from discrete populations on the NE Atlantic coast. By using eight recently developed microsatellite markers, genetic structure was compared between populations from the Danish Strait in the south to the Barents Sea in the north (56-79°N). Urchins are spread by pelagic larvae and may be transported...
