WebThe last time such a strong El Niño occurred (1997–98), there were large population declines throughout the Eastern Pacific marine food web. A strong La Niña then followed in 1998–99 and had the opposite impact: stronger east-to-west trade winds increased upwelling nutrients and fertilized one of the biggest phytoplankton blooms in the ... WebDiatoms have two distinct shapes: a few (centric diatoms) are radially symmetric, while most (pennate diatoms) are broadly bilaterally symmetric. A unique feature of diatom anatomy is that they are surrounded by a cell wall made of silica (hydrated silicon dioxide), called a frustule. ... Red: [chlorophyll autofluorescence] ...
WebBacillariophyceae or diatoms are distinguished by chloroplasts that have four surrounding membranes, thylakoids in stacks of three, fucoxanthin that masks chlorophyll-a and -c, chrysolaminarin as the photosynthetic reserve product, and a siliceous frustule that makes up the external covering (Table I; Chap. 15).
