Associated bacteria affect sexual reproduction by altering gene expression and metabolic processes in a biofilm inhabiting diatom [PDF]

open access: yes, 2019
Diatoms are unicellular algae with a fundamental role in global biogeochemical cycles as major primary producers at the base of aquatic food webs. In recent years, chemical communication between diatoms and associated bacteria has emerged as a key factor

Diatom Cooccurrence Shows Less Segregation than Predicted from Niche Modeling. [PDF]

open access: yesPLoS ONE, 2016
Species cooccurrence patterns give significant insights into the processes shaping communities. While biotic interactions have been widely studied using cooccurrence analyses in animals and larger plants, studies about cooccurrences among micro-organisms

Freshwater diatom biomonitoring through benthic kick-net metabarcoding.

open access: yesPLoS ONE, 2020
Biomonitoring is an essential tool for assessing ecological conditions and informing management strategies. The application of DNA metabarcoding and high throughput sequencing has improved data quantity and resolution for biomonitoring of taxa such as ...

Distance decay of similarity in neotropical diatom communities. [PDF]

open access: yesPLoS ONE, 2012
BackgroundThe regression of similarity against distance unites several ecological phenomena, and thus provides a highly useful approach for illustrating the spatial turnover across sites.

Diatom Proteomics Reveals Unique Acclimation Strategies to Mitigate Fe Limitation [PDF]

open access: yes, 2015
Phytoplankton growth rates are limited by the supply of iron (Fe) in approximately one third of the open ocean, with major implications for carbon dioxide sequestration and carbon (C) biogeochemistry.

Influence of the Diatomite Specie on the Peak and Residual Shear Strength of the Fine-Grained Soil

open access: yesApplied Sciences, 2021
Diatomite is a powdering mineral mainly composed of diatom microfossils present in marine and lacustrine soils, which influences their physical and mechanical properties.

Investigation of Energy-Absorbing Properties of a Bio-Inspired Structure

open access: yesMetals, 2021
Numerous engineering applications require lightweight structures with excellent absorption capacity. The problem of obtaining such structures may be solved by nature and especially biological structures with such properties. The paper concerns an attempt
