WebSep 27, 2024 · The diatoms came out positive in the bones; however, the water sample from the gutter didn’t test positive for diatoms. Thus, due to the diatom-negative status of water, diatoms from bones can’t be compared with suspected water samples. Since diatoms in bones can arise as a result of contamination too, death cannot be concluded … WebYes, and yes. Climate affects diatoms in complex ways. As the planet warms due to the increase in carbon dioxide, scientists predict that larger marine plankton, like diatoms, will decrease compared to smaller plankton, like coccolithophores and cyanobacteria. In lakes and rivers, a changing climate alters river flow in many parts of the world.
