Effect of the anisotropy on the glory structure of molecule-molecule scattering cross sections [PDF]

open access: yes, 2011
Total (elastic + rotationally inelastic) integral cross sections are computed for O$_2(^3\Sigma_g^-)$-O$_2(^3\Sigma_g^-)$ using a recent ab initio potential energy surface.

Long range intermolecular forces in triatomic systems: connecting the atom-diatom and atom-atom-atom representations

open access: yes, 2005
The long-range forces that act between three atoms are analysed in both atom-diatom and atom-atom-atom representations. Expressions for atom-diatom dispersion coefficients are obtained in terms of 3-body nonadditive coefficients.

Temperature and light requirements for growth of two diatom species (Bacillariophyceae) isolated from an Arctic macroalga [PDF]

open access: yes, 2006
In the present study, two abundant epiphyticdiatom taxa were isolated from the assimilation hairs ofthe brown macroalga Chordaria flagelliformis collected inthe Arctic Kongsfjorden (Spitsbergen, Norway), establishedas unialgal cultures and their growth ...

Substrate type selection in diatom based lake water quality assessment

open access: yesKnowledge and Management of Aquatic Ecosystems, 2021
Various studies report contrasting results on the substrate-type effect on diatom community composition, but the particularly important question is whether or not it affects diatom-based assessments of water quality. We investigated whether the substrate

Climate variability in SE Europe since 1450 AD based on a varved sediment record from Etoliko Lagoon (Western Greece) [PDF]

open access: yes, 2017
To achieve deeper understanding of climate variability during the last millennium in SE Europe, we report new sedimentological and paleoecological data from Etoliko Lagoon, Western Greece.

Research on the Characteristics of Benthic Diatom in the Longjiang River in Guangxi and Its Relationships with Heavy Metals Ions Pollution

open access: yesChemical Engineering Transactions, 2017
This paper performs sampling and analysis of benthic diatom communities in the Longjiang River in Guangxi province in both May and July. The positive correlation between dominant diatom communities and the contents of heavy metals in the water were ...

A tripartite model system for Southern Ocean diatom-bacterial interactions reveals the coexistence of competing symbiotic strategies

open access: yesISME Communications, 2022
Southern Ocean (SO) diatoms play an important role in global carbon flux, and their influence on carbon export is directly linked to interactions with epiphytic bacteria.

Culturing Diatoms

open access: yes, 2023
In this chapter, we provide information on cultures of diatoms, starting with a brief introduction of the history of diatom culture collections. We present a synopsis of diatom strains currently available in culture collections and their representation in terms of habitat diversity, geographical distribution, phylogeny and taxonomic diversity.

The last glacial-interglacial cycle in Lake Ohrid (Macedonia/Albania): testing diatom response to climate [PDF]

open access: yes, 2010
Lake Ohrid is a site of global importance for palaeoclimate research. This study presents results of diatom analysis of a ca. 136 ka sequence, Co1202, from the northeast of the lake basin.

Eighty years of food-web response to interannual variation in discharge recorded in river diatom frustules from an ocean sediment core. [PDF]

open access: yes, 2017
Little is known about the importance of food-web processes as controls of river primary production due to the paucity of both long-term studies and of depositional environments which would allow retrospective fossil analysis.
