Species don’t live in isolation; they live in very tangled, complicated, interconnected webs. So studying them in isolation has only limited utility, much like studying cells cultured in a sterile petri dish. These laboratory studies can yield suggestive and promising results, but these results are not always applicable to how the cells behave in the context of an organism, much less as part of a species in an ecosystem.

The increased carbon dioxide that humanity has been relentlessly pumping into the air since the onset of the Industrial Revolution is acidifying the oceans. Studies done to determine what this ocean acidification will do to fish have mostly assessed the direct effect of elevated CO2 levels on the fishes’ growth and physiology, but they have not taken into account any effects ocean acidification might have on food webs as a whole.

Scandinavian marine biologists have tried to rectify this situation by studying the effects of ocean acidification in 10 mesocosms—fiberglass tanks seeded with rocks, sediment, plankton, and other microorganisms—they set up off the west coast of Sweden. Five were controls; the other five got elevated CO2, set to mimic levels that the Intergovernmental Panel on Climate Change calculates could occur by the end of this century. Those estimates are about 760 μatm (short for micro-atmospheres) pCO2, compared to today’s 380 μatm pCO2). Being Scandinavian, these researchers examined the survival of… herring.

The direct chemical effect of our CO2 emissions on our planet’s oceans gets far less attention than the indirect effects caused by global warming. But CO2 lowers the seawater’s pH—known as “ocean acidification”—and this  has been shown to be a serious problem for many species. Acidification makes it harder for critters with calcium carbonate shells to grow them, and it even changes the way fish behave.

The majority of studies that have looked at ocean acidification’s impact have fallen into two basic categories: laboratory experiments with carefully isolated conditions and species, and surveys of life at natural CO2 seeps on the seafloor. Each category has drawbacks and advantages. Lab experiments are carefully controlled and can provide unambiguous results. Surveys at natural CO2 seeps can integrate more processes, like species interactions or adaptation over generations. But it’s also true that seeps are surrounded by “normal” ecosystems that could be lending support.

Carbon offsets

A group of University of Adelaide researchers led by Silvan Goldenberg set out to help fill in the span between those two categories by designing controlled experiments that stepped up the ecological complexity. In 1,800 containers called “mesocosms,” the researchers combined species to form tiny ecosystems. The stars of the show were eight species of fish and shrimp, which swam among a rich supporting cast of over 90 other species—everything from algae and microbes to predators.
