Overview

Top Research Topics at African Journal of Marine Science?

African Journal of Marine Science primarily focuses on research topics in Fishery, Ecology, Oceanography, Fishing and Cape. While the journal focused on Fishery, it was also able to explore topics like Sardine, Anchovy and Predation. The journal is mostly focused on Anchovy, specifically Engraulis.

Most of the works presented in the journal deals with Ecology but it intersects with the subject of Zoology. The studies in Oceanography featured incorporate elements of Phytoplankton and Climatology. African Journal of Marine Science covers various topics on Fishing such as Fisheries management and Catch per unit effort.

The Cape study featured in African Journal of Marine Science draws connections with the study of Hake. It focuses on Upwelling as well as the interrelated topic of Sea surface temperature.

  • Fishery (49.18%)
  • Ecology (33.66%)
  • Oceanography (32.35%)

What are the most cited papers published in the journal?

  • Worldwide large-scale fluctuations of sardine and anchovy populations (444 citations)
  • World-wide fluctuations of sardine and anchovy stocks: the regime problem (354 citations)
  • Marine alien species of South Africa — status and impacts (219 citations)

Research areas of the most cited articles at African Journal of Marine Science:

Fishery, Oceanography, Ecology, Upwelling and Cape are the main subjects of interest in the journal publications. The most cited publications hold forums on Fishery that merge themes from other disciplines such as Sardine, Anchovy and Predation. While Oceanography is the focus of the most cited articles, it also provides insights into the studies of Phytoplankton and Ecosystem.

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

  • Ecology
  • Genus
  • Oceanography

The previous edition focused in particular on these issues:

The topics of Fishery, Oceanography, Ecology, Estuary and Zoology are the focal point of discussions in the journal. African Journal of Marine Science focused on Fishery research but expanded to cover Photic zone. It links adjacent topics like Oceanography with Phytoplankton.

It deals with Estuary in conjunction with Ecosystem and similar fields in Hake, Benthic zone, Particle-size distribution and Seafloor spreading. The presented research on Zoology deals specifically with Body condition but it also addresses topics in Argyrosomus japonicus, Squid, Size composition and Loligo reynaudii. The study of Marine protected area and how it intertwines with concepts under Environmental planning were explored in the presented Fishing research.

The most cited articles from the last journal are:

  • Large-scale movements and site fidelity of two bull sharks Carcharhinus leucas estimated from a double-tagging experiment at Réunion Island (southwest Indian Ocean) (1 citations)
  • Potential impact of marine heatwaves on selected phytoplankton adapted to the Gulf of Guinea during stable hydrographic periods (1 citations)
  • Evaluating Kenya’s coastal gillnet fishery: trade-offs in recommended mesh-size regulations (1 citations)

Papers citation over time

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, 0.00% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 69.70% were posted by at least one author from the top 10 institutions publishing in the journal. Another 12.12% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 6.06% of all publications and 12.12% 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.
