Neotropical Ichthyology

Top Research Topics at Neotropical Ichthyology?

The journal primarily focuses on research topics in Ecology, Zoology, Characiformes, Anatomy and Fishery. It explores research in Ecology and the adjacent study of Structural basin. The Structural basin study featured in the journal draws connections with the study of Tributary.

Zoology research featured in the journal incorporates concerns from various other topics such as Loricariidae, Catfish and Teleostei. Pimelodidae is a focus of the presented Catfish works and it dives deep in Pimelodidae. The studies tackled, which mainly focus on Characiformes, apply to Characidae as well.

Neotropical Ichthyology focused on Anatomy research but expanded to cover Fish fin. Fishery research presented is mostly focused on the subject of Fishing. The majority of Taxonomy (biology) studies presented zero in on Systematics.

Research areas of the most cited articles at Neotropical Ichthyology:

The journal publications investigate areas of study like Ecology, Zoology, Fishery, Characidae and Characiformes. Teleostei, Ostariophysi and Karyotype are some topics wherein Zoology research discussed in the journal papers has an impact. In addition to Characiformes research, the journal papers aim to explore topics under Taxonomy (biology), Neotropical fish and Anatomy.

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 aim of the journal is to expand the discussion of research in Ecology, Zoology, Fishery, Characiformes and Biodiversity. In addition to Ecology research, it aims to explore topics under Genetic structure and STREAMS. The work on Zoology tackled in Neotropical Ichthyology brings together disciplines like Species complex and Characidae.

The Fishery works featured in it incorporate elements from Hydropower, Tributary and Amazon rainforest. While work presented in Neotropical Ichthyology provided substantial information on Characiformes, it also covered topics in Neoteny and Near-threatened species. It addresses concerns in Biodiversity which are intertwined with other disciplines, such as Endemism, IUCN Red List, Extinction and Aquaculture.

The most cited articles from the last journal are:

• Fish die-off in river and reservoir: A review on anoxia and gas supersaturation (2 citations)
• Urban market amplifies strong species selectivity in Amazonian artisanal fisheries (1 citations)
• Under the surface: what we know about the threats to subterranean fishes in Brazil (1 citations)

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, 10.00% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 66.67% were posted by at least one author from the top 10 institutions publishing in the journal. Another 14.81% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 11.11% of all publications and 7.41% 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.
