Abstract

A polyphasic study of four Stigonematales cyanobacteria from tropical Australia (Queensland) revealed production of the hepatotoxins microcystins (MC-LR, MC-LA, MC-LF, MC-FR and demethyl-MC-LR) by Fischerella sp. NQAIF311 isolated from a seasonal creek. Total microcystin content reached 43 ?g g(-1) dry weight. Phylogeny demonstrated high sequence similarities for 16S rRNA (99%), mcyE (97%) and mcyD (95%) genes with microcystin-producing Fischerella sp. CENA161 from Brazil. This is the first report of a cyanotoxin-producing Stigonematal in Australia. Copyright © 2014 Elsevier Ltd. All rights reserved.

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal TOXICON due to its progression and the good impact it has achieved in recent years, according to the agency WoS (JCR), it has become a reference in its field. In the year of publication of the work, 2014, it was in position 115/255, thus managing to position itself as a Q2 (Segundo Cuartil), in the category Pharmacology & Pharmacy. Notably, the journal is positioned en el Cuartil Q2 para la agencia Scopus (SJR) en la categoría Toxicology.

From a relative perspective, and based on the normalized impact indicator calculated from World Citations provided by WoS (ESI, Clarivate), it yields a value for the citation normalization relative to the expected citation rate of: 1.13. This indicates that, compared to works in the same discipline and in the same year of publication, it ranks as a work cited above average. (source consulted: ESI Nov 14, 2024)

This information is reinforced by other indicators of the same type, which, although dynamic over time and dependent on the set of average global citations at the time of their calculation, consistently position the work at some point among the top 50% most cited in its field:

  • Weighted Average of Normalized Impact by the Scopus agency: 1.07 (source consulted: FECYT Feb 2024)
  • Field Citation Ratio (FCR) from Dimensions: 3.46 (source consulted: Dimensions Jul 2025)

Specifically, and according to different indexing agencies, this work has accumulated citations as of 2025-07-20, the following number of citations:

  • WoS: 30
  • Scopus: 33
  • Europe PMC: 8

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2025-07-20:

  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 52 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:
