Diatom in a sentence

The project aims to document the diatom and bacterial species living on marine megafauna or large animals.

In lower organisms such as diatoms, the strong light manipulation associated with the periodic nanostructure on diatom frustule walls might influence the collection of more light into the photoreceptors for more optimized photosynthetic efficiencies ().

About half of these are also found in the T. pseudonana genome, attesting their ancient incorporation in the diatom lineage.

Additional factors such as predation by zooplankton and ammonium -based regenerated production also have a role to play in the annual diatom cycle.

A new diatom cell of maximum size, the initial cell, forms within the auxospore thus beginning a new generation.

As a result, after each division cycle the average size of diatom cells in the population gets smaller.

A single diatom at first look may not seem to be a cell, but diatoms are eukaryotic organisms with common organelles such as a nucleus, mitochondria, and golgi complex.

Cladophora is frequently covered with Cocconeis, an elliptically shaped diatom; Vaucheria is often covered with small forms.

Climate Change 2007: Synthesis Report. 104. could thus in theory result in a significant loss of diatom diversity, although from current knowledge it is impossible to say if this would occur rapidly or only over many tens of thousands of years.

Curiously the mitochondrion and the plastid of the diatom remain functional.

Diatom communities are a popular tool for monitoring environmental conditions, past and present, and are commonly used in studies of water quality.

Forensic research The main goal of diatom analysis in forensics is to differentiate a death by submersion from a post-mortem immersion of a body in water.

Fossil record Paralia sulcata diatom imaged using the University of Tasmania scanning electron microscope.

In most circumstances, this mixing also replenishes nutrients in the upper mixed layer, setting the scene for the next round of diatom blooms.

In the open ocean, the diatom (spring) bloom is typically ended by a shortage of silicon.

Methods and applications of Cenozoic marine diatom biostratigraphy.

The Cretaceous record of diatoms is limited, but recent studies reveal a progressive diversification of diatom types.

The diatom endosymbiont is bounded by a single membrane, inside it are chloroplasts with four membranes.

The duration of diatom species ranges have been documented through the study of ocean cores and rock sequences exposed on land.

The life-cycle of most diatoms can be described as 'boom and bust' and the Black Sea is no exception, with diatom blooms occurring in surface waters throughout the year, most reliably during March.
