Research areas of the most cited articles at New Zealand Journal of Marine and Freshwater Research:

The most cited articles primarily focus on research topics in Ecology, Fishery, Oceanography, Hydrology and STREAMS. The most cited publications with studies in Fishery featured incorporate elements of Freshwater fish, Zoology and Anguilla dieffenbachii. While work presented in the most cited articles provide substantial information on Oceanography, it also covers topics in Phytoplankton and Climatology.

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

  • Ecology
  • Genus
  • Zoology

The previous edition focused in particular on these issues:

The journal tackles a plethora of topics, such as Oceanography, Fishery, Ecology, Zoology and Habitat. The featured Oceanography studies mainly concentrate on Aotearoa but also cover areas of interest in Physical oceanography, Amphidomataceae and Dinophyceae. It focuses on Fishery but the discussions also offer insight into other areas such as Ecosystem-based management, Oncorhynchus, Chinook wind, Larva and Life history.

Topics like Estuary, Invertebrate, Wetland, Community composition and Seasonality are tackled as part of the discussions on Ecology. Reproduction, Threatened species, Body size, Sperm and Population structure are some topics wherein Zoology research discussed in it have an impact. The presented studies in Endangered species fall within the purview of Habitat but it also intertwines with topics in Limit (mathematics) and Genidens barbus.

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, 3.28% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 88.14% were posted by at least one author from the top 10 institutions publishing in the journal. Another 5.08% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 1.69% of all publications and 5.08% 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.
