Sentences with phrase «natural diatom»

These results are in accordance with observations from short - term natural diatom community experiments [10,12], where temperature exerted a stronger influence than pCO2, but statistically pCO2 was still a contributor to observed effects.

In the final paper of this issue, Tatters et al. [66] study the competitiveness of natural diatom communities incubated under future environmental conditions for two weeks, after which the dominant species were isolated and then incubated again for over a year before recombining the now conditioned species to reconstruct the original community.

We incubated a natural diatom community from coastal New Zealand waters in a short - term incubation experiment using a factorial matrix of temperature and CO2, and measured effects on community structure.

So many diatoms died, in fact, that they overwhelmed any natural systems for decay and fell in large numbers below 500 meters in depth.

Diatomaceous earth is an all - natural powder made from the fossilized remains of tiny, hard - shelled algae called diatoms.

Diatomaceous earth, sometimes referred to as «DE,» is a natural substance that is actually created from the remains of diatoms, microscopic water plants that are like algae.

As discussed in Natural Cycles of Ocean Acidification, diatoms are large, produce siliceous shells, and more rapidly shuttle CO2 from the surface to ocean depths.

At any rate, when «normal» rain containing natural carbonic acid falls upon silicon - containing sedimentary rocks formed over eons from the shells of tiny marine creatures — radiolarians, diatoms and some sponges — this «siliceous» rock combines with the carbonic acid to form ions of bicarbonate.

Fossil evidence shows that during past periods of natural global warming, many animals, from horses to gophers to diatoms, shrunk.

Inter-specific competition was found to be similar in both the unconditioned natural and the conditioned artificial community, suggesting that for diatom communities, short - term manipulative experiments may be used to predict the effects of long - term environmental forcing on community structure.
