Overview

Top Research Topics at African Journal of Aquatic Science?

The journal is mainly concerned with subjects like Ecology, Fishery, Water quality, Estuary and Aquatic science. The work tackled in African Journal of Aquatic Science goes beyond the discipline of Ecology as it also encompasses Hydrology. The Fishery works featured in the journal incorporate elements from Aquatic animal, Predation, Teleostei and Animal science.

The research on Water quality featured in it combines topics in other fields like Water pollution, Eutrophication and Pollution. While Estuary is the focus of the journal, it also provided insights into the studies of Salinity and Zooplankton. The journal connects research in Zooplankton with the related topic of Plankton.

The journal connects the study in Aquatic science with the closely related area of Environmental ethics. The journal links adjacent topics like Invertebrate with Benthic zone.

The previous edition focused in particular on these issues:

The scientific interests tackled in the journal are Water quality, Fishery, Hydrology, Water resource management and Zooplankton. While work presented in African Journal of Aquatic Science provided substantial information on Water quality, it also covered topics in Phytoplankton, Aquatic ecosystem, Mangrove ecosystem and Surface water. Some problems in Fishery that were presented in the journal overlapped with concepts under Freshwater fish, Freshwater ecosystem, STREAMS, Fish species and Threatened species.

The work on Hydrology tackled in the journal brings together disciplines like Invertebrate, Sediment and Vegetation. Research on Zooplankton presented in African Journal of Aquatic Science concerns the broader topic of Ecology. African Journal of Aquatic Science tackles research works in Ecology as well as Bass (sound).

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, 3.64% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 41.51% were posted by at least one author from the top 10 institutions publishing in the journal. Another 24.53% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 15.09% of all publications and 18.87% 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.

Related Online Degrees & Career Pathways

Studying Ecology and Evolution opens diverse opportunities, often intersecting with healthcare and environmental management fields. Many professionals enhance their expertise by pursuing advanced education through programs like the fastest online master's in healthcare administration, which equips students with essential leadership skills for managing healthcare organizations efficiently.

For those interested in clinical roles, accelerated options such as one year nurse practitioner programs provide a quick pathway to becoming a Family Nurse Practitioner (FNP). This can be particularly valuable for ecologists focusing on public health impacts in communities affected by environmental changes.

Advancing within nursing specialties is also possible by obtaining an acute care certification for fnp, allowing practitioners to deliver specialized care in critical settings. Such certifications highlight the growing demand for interdisciplinary knowledge combining ecology, evolution, and acute care expertise.

Additionally, many graduates explore roles in data management and analytics related to ecological studies. Pursuing a health information management bachelor degree salary career path can offer stability and impactful opportunities to manage environmental health data effectively.
