Marine microzooplankton are indirectly affected by ocean acidification through direct effects on their phytoplankton prey

To date there is little evidence to suggest that marine microzooplankton are directly affected by ocean acidification (OA), and few studies have explored indirect effects of OA on microzooplankton. 350 more words


OCEANS: So where have all our fish gone anyway? Think small!

“If there is nothing for fish to eat, there are no fish for you to eat!”

If you spend much time exploring the intertidal waters of Cobscook Bay, you are likely to have seen a variety of creatures that look like shrimp. 1,005 more words

Ocean acidification challenges copepod reproductive plasticity

Ocean acidification is challenging phenotypic plasticity of individuals and populations. Calanoid copepods (zooplankton) are shown to be fairly plastic against altered pH conditions, and laboratory studies indicate that transgenerational effects are one mechanism behind this plasticity. 214 more words


Effects of high CO2 and warming on a Baltic Sea microzooplankton community

Global warming and ocean acidification are among the most important stressors for aquatic ecosystems in the future. To investigate their direct and indirect effects on a near-natural plankton community, a multiple-stressor approach is needed. 210 more words


Quantifying preferences and responsiveness of marine zooplankton to changing environmental conditions using microfluidics

Global environmental change significantly affects marine species composition. However, analyzing the impact of these changes on marine zooplankton communities was so far mostly limited to assessing lethal doses through mortality assays and hence did not allow a direct assessment of the preferred conditions, or preferendum. 130 more words


Ocean acidification increases the accumulation of toxic phenolic compounds across trophic levels

Increasing atmospheric CO2 concentrations are causing ocean acidification (OA), altering carbonate chemistry with consequences for marine organisms. Here we show that OA increases by 46–212% the production of phenolic compounds in phytoplankton grown under the elevated CO2 concentrations projected for the end of this century, compared with the ambient CO2 level. 118 more words


Life cycle and early development of the thecosomatous pteropod Limacina retroversa in the Gulf of Maine, including the effect of elevated CO2 levels

Thecosomatous pteropods are pelagic molluscs with aragonitic shells. They are considered to be especially vulnerable among plankton to ocean acidification, but to recognize changes due to anthropogenic forcing a baseline understanding of their life history is needed. 212 more words
