Oikos

Top Research Topics at Oikos?

The journal is mainly concerned with subjects like Ecology, Predation, Botany, Habitat and Zoology. The Ecology study featured in Oikos draws connections with the study of Biological dispersal. Oikos explores topics in Predation which can be helpful for research in disciplines like Trophic level and Foraging.

Topics in Botany explored in the journal were investigated in conjunction with research in Agronomy and Horticulture. In it, Biodiversity and Species diversity are investigated in conjunction with one another to address concerns in Species richness research. It connects research in Competition (biology) with the related topic of Interspecific competition.

Research areas of the most cited articles at Oikos:

The most cited papers investigate areas of study like Ecology, Predation, Habitat, Botany and Species richness. Herbivore, Abundance (ecology), Ecosystem, Competition (biology) and Species diversity are all topics related to Ecology research discussed in the journal articles. While the most cited papers focused on Botany, they were also able to explore topics like Nutrient and Agronomy.

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

• Ecology
• Botany
• Genus

The previous edition focused in particular on these issues:

The journal was organized to reinforce research efforts on Ecology, Seed dispersal, Biological dispersal, Zoology and Competition (biology). Ecology, which encompasses Habitat, Ecosystem, Predation, Herbivore and Abundance (ecology), is the main subject of Oikos. Some problems in Ecosystem that were presented in Oikos overlapped with concepts under Biomass (ecology) and Trophic level.

Studies on Seed dispersal discussed in Oikos link to the field of Frugivore. Biological dispersal research is the primary subject tackled in it with a focus on Metapopulation.

The most cited articles from the last journal are:

• A conceptual guide to measuring species diversity (13 citations)
• Below- and aboveground traits explain local abundance, and regional, continental and global occurrence frequencies of grassland plants (5 citations)
• Migrant birds disperse haemosporidian parasites and affect their transmission in avian communities (4 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.

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, 4.90% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 25.26% were posted by at least one author from the top 10 institutions publishing in the journal. Another 8.25% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 25.26% of all publications and 41.24% 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.
