The evolution of diatoms and their biogeochemical functions SUMMARY: This article talks about the evolution, cell structure, and ecological role of diatoms. The first section is an introduction to what diatoms are. The second section talks about the evolution of photosynthesis (from cyanobacteria to eukaryotes with chloroplast). The third section explains the significance of the… Continue reading The evolution of diatoms and their biogeochemical functions

Diatom ecological response to deposition of the 833-850 CE White River Ash (east lobe) ashfall in a small subarctic Canadian lake SUMMARY: This article looks at diatom population differences affected by volcanic rock deposits into a lake before, during, and after an eruption event. Results showed that diatom population patterns were able to quickly return… Continue reading What Diatoms Can Tell Us
