Overview

Top Research Topics at Extremophiles?

The journal covers a variety of subjects, including Biochemistry, Microbial ecology, Bacteria, Microbiology and Enzyme. Biochemistry research presented in the journal encompasses a variety of subjects, including Molecular biology and Halophile. Molecular biology study tackled is connected to the field of Gene.

The journal addresses concerns in Microbial ecology which are intertwined with other disciplines, such as Ecology, Botany, Microorganism, Archaea and Extreme environment. It focuses on Ecology as well as the interrelated topic of Microbial population biology. Extremophiles investigates Botany research which frequently intersects with Actinobacteria.

The research on Microbiology tackled can also make contributions to studies in the areas of 16S ribosomal RNA and Strain (chemistry). The journal explores research in Phylogenetic tree and overlapping concepts in Phylogenetics to expand the discourse in 16S ribosomal RNA. The journal concentrates on Enzyme topics that focus on Molecular mass and Enzyme assay.

  • Biochemistry (43.60%)
  • Microbial ecology (17.54%)
  • Bacteria (15.92%)

What are the most cited papers published in the journal?

  • Halophilic adaptation of enzymes. (439 citations)
  • Pyrolobus fumarii, gen. and sp. nov., represents a novel group of archaea, extending the upper temperature limit for life to 113 degrees C. (417 citations)

Research areas of the most cited articles at Extremophiles:

The most cited papers mostly deal with topics like Biochemistry, Microbial ecology, Bacteria, Ecology and Microbiology. The Biochemistry research tackled in the journal papers is interrelated with Halophile which concerns subjects like Halotolerance. While Microbial ecology is the key highlight in the journal papers, thet also covered some subjects on Botany and Actinobacteria.

What topics the last edition of the journal is best known for?

  • Enzyme
  • Bacteria
  • Gene

The previous edition focused in particular on these issues:

The journal mainly deals with areas of study such as Microbial ecology, Gene, Ecology, Biochemistry and Bacteria. In addition to Microbial ecology research, the journal aims to explore topics under Botany, Planctomycetes, Microorganism, Environmental chemistry and Metagenomics. The studies in Genome, Ars operon and RNA under the umbrella field of Gene overlap with concepts in Acidithiobacillus.

Biochemistry studies presented in Extremophiles focus on topics such as Thermophile, Transcriptome, Threonine, Electron donor and Metabolism. While Extremophiles focused on Thermophile, it was also able to explore topics like Psychrophile, Protein engineering and Metabolic pathway. The studies on Bacteria discussed can also contribute to research in the domains of Nitrate, Strain (chemistry) and Methane.

The most cited articles from the last journal are:

  • Fungal diversity present on rocks from a polar desert in continental Antarctica assessed using DNA metabarcoding. (4 citations)
  • Assessment of fungal diversity present in lakes of Maritime Antarctica using DNA metabarcoding: a temporal microcosm experiment. (4 citations)
  • The largest moss carpet transplant in Antarctica and its bryosphere cryptic biodiversity (2 citations)

Papers citation over time

A key indicator for each journal is its effectiveness in reaching other researchers with the papers published at that venue.

The chart below presents the interquartile range (first quartile 25%, median 50% and third quartile 75%) of the number of citations of articles over time.

The top authors publishing in Extremophiles (based on the number of publications) are:

  • Koki Horikoshi (31 papers) absent at the last edition,
  • Mosè Rossi (28 papers) absent at the last edition,
  • Garabed Antranikian (28 papers) published 1 paper at the last edition,
  • Aharon Oren (26 papers) absent at the last edition,
  • Chiaki Kato (25 papers) absent at the last edition.

The overall trend for top authors publishing in this journal is outlined below. The chart shows the number of publications at each edition of the journal for top authors.

Only papers with recognized affiliations are considered

The top affiliations publishing in Extremophiles (based on the number of publications) are:

  • Russian Academy of Sciences (80 papers) published 2 papers at the last edition, 6 less than at the previous edition,
  • Chinese Academy of Sciences (59 papers) published 1 paper at the last edition, 1 less than at the previous edition,
  • Japan Agency for Marine-Earth Science and Technology (54 papers) published 1 paper at the last edition,
  • Centre national de la recherche scientifique (35 papers) published 1 paper at the last edition the same number as at the previous edition,
  • Spanish National Research Council (34 papers) published 3 papers at the last edition.

The overall trend for top affiliations publishing in this journal is outlined below. The chart shows the number of publications at each edition of the journal for top affiliations.

Publication chance based on affiliation

The publication chance index shows the ratio of articles published by the best research institutions in the journal edition to all articles published within that journal. The best research institutions were selected based on the largest number of articles published during all editions of the journal.

The chart below presents the percentage ratio of articles from top institutions (based on their ranking of total papers).Top affiliations were grouped by their rank into the following tiers: top 1-10, top 11-20, top 21-50, and top 51+. Only articles with a recognized affiliation are considered.

During the most recent 2021 edition, 7.14% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 23.08% were posted by at least one author from the top 10 institutions publishing in the journal. Another 20.51% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 2.56% of all publications and 53.85% were from other institutions.

Returning Authors Index

A very common phenomenon observed among researchers publishing scientific articles is the intentional selection of journals they have already attended in the past. In particular, it is worth analyzing the case when the authors participate in the same journal from year to year.

The Returning Authors Index presented below illustrates the ratio of authors who participated in both a given as well as the previous edition of the journal in relation to all participants in a given year.

Returning Institution Index

The graph below shows the Returning Institution Index, illustrating the ratio of institutions that participated in both a given and the previous edition of the conference in relation to all affiliations present in a given year.

The experience to innovation index

Our experience to innovation index was created to show a cross-section of the experience level of authors publishing in a journal. The index includes the authors publishing at the last edition of a journal, grouped by total number of publications throughout their academic career (P) and the total number of citations of these publications ever received (C).

The group intervals were selected empirically to best show the diversity of the authors' experiences, their labels were selected as a convenience, not as judgment. The authors were divided into the following groups:

  • Novice - P < 5 or C < 25 (the number of publications less than 5 or the number of citations less than 25),
  • Competent - P < 10 or C < 100 (the number of publications less than 10 or the number of citations less than 100),
  • Experienced - P < 25 or C < 625 (the number of publications less than 25 or the number of citations less than 625),
  • Master - P < 50 or C < 2500 (the number of publications less than 50 or the number of citations less than 2500),
  • Star - P ≥ 50 and C ≥ 2500 (both the number of publications greater than 50 and the number of citations greater than 2500).

The chart below illustrates experience levels of first authors in cases of publications with multiple authors.
