Application of 18S rDNA Clone Library to Detect Diatom Population Diversity in Dianchi#br# [PDF]

open access: yesFayixue Zazhi, 2019
Objective To detect the diatom population diversity in Dianchi by constructing a 18S rDNA clone library. Methods DNA from diatoms in 6 water samples of Dianchi was amplified with diatom 18S rDNA specific primer.The 18S rDNA clone library was constructed,

Influence of diatom diversity on the ocean biological carbon pump

open access: yesNature Geoscience, 2017
Diatoms sustain the marine food web and contribute to the export of carbon from the surface ocean to depth. They account for about 40% of marine primary productivity and particulate carbon exported to depth as part of the biological pump.

Diatom Frustule Silica Exhibits Superhydrophilicity and Superhemophilicity.

open access: yesACS Nano, 2020
Special surface wettability attracts significant attention. In this study, dramatic differences in wettability are demonstrated for microparticles with the same chemical composition, SiO2. One is natural silica prepared from diatom, Melosira nummuloides,

Sensitivity of freshwater periphytic diatoms to agricultural herbicides [PDF]

open access: yes, 2009
The biomonitoring of pesticide pollution in streams and rivers using algae such as diatoms remains difficult. The responses of diatomcommunities to toxic stress in streamwater are disturbed by the variations of environmental parameters.

Simonsenia aveniformis sp nov (Bacillariophyceae), molecular phylogeny and systematics of the genus, and a new type of canal raphe system [PDF]

open access: yes, 2015
The genus Simonsenia is reviewed and S. aveniformis described as new for science by light and electron microscopy. The new species originated from estuarine environments in southern Iberia (Atlantic coast) and was isolated into culture. In LM, Simonsenia

The Phaeodactylum genome reveals the evolutionary history of diatom genomes

open access: yesNature, 2008
Diatoms are photosynthetic secondary endosymbionts found throughout marine and freshwater environments, and are believed to be responsible for around one-fifth of the primary productivity on Earth.

Palaeolimnology of Lake Sapanca and identification of historic earthquake signals, Northern Anatolian Fault Zone (Turkey) [PDF]

open access: yes, 2009
Lake Sapanca is located on a strand of the Northern Anatolian Fault Zone (NAFZ, Turkey), where a series of strong earthquakes (Ms >6.0) have occurred over the past hundred years. Identifying prehistoric earthquakes in and around Lake Sapanca is key to a

Evolutionary genomics of the cold-adapted diatom Fragilariopsis cylindrus

open access: yesNature, 2017
The Southern Ocean houses a diverse and productive community of organisms. Unicellular eukaryotic diatoms are the main primary producers in this environment, where photosynthesis is limited by low concentrations of dissolved iron and large seasonal ...
