Overview

Top Research Topics at Grana?

The main points discussed in the journal deals with Pollen, Botany, Spore, Palynology and Ecology. Stamen is a major topic of Pollen research. While Grana focused on Botany, it was also able to explore topics like Morphology (linguistics), Horticulture and Morphology (biology).

Grana connects the study in Spore with the closely related area of Cladosporium. The work on Cladosporium addressed in Grana expands to the thematically related Alternaria. More specifically, the research on Ecology in it is related to Vegetation.

The works on Paleontology deal in particular with Cretaceous.

  • Pollen (66.33%)
  • Botany (63.42%)
  • Spore (11.20%)

What are the most cited papers published in the journal?

  • Tree pollen spectra in the stockholm region (sweden), 1973–1980 (285 citations)
  • An Introduction to a Scandinavian Pollen Flora (249 citations)
  • A model to predict the beginning of the pollen season (209 citations)

Research areas of the most cited articles at Grana:

The journal publications aim to foster the development of research in Pollen, Botany, Ecology, Spore and Horticulture. While work presented in the most cited papers provide substantial information on Pollen, it also covers topics in Poaceae and Physical geography. The published articles facilitate the exploration of Botany in relation to the field of Aperture (botany).

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

  • Botany
  • Ecology
  • Genus

The previous edition focused in particular on these issues:

Grana investigates areas of study like Pollen, Botany, Palynology, Morphology (biology) and Genus. While Pollen is the focus of Grana, it also provided insights into the studies of Paleontology, Taphonomy, Cretaceous, Microscopy and Physical geography. It served as a forum through which researchers explored different topics like Botany and Lycopodiopsida.

Grana explores topics in Palynology which can be helpful for research in disciplines like Zoology, Taxonomy (biology), Horticulture, Spore and Ziziphus lotus. The work on Morphology (biology) tackled in the journal brings together disciplines like Ecotype, Bromeliaceae, Bromelioideae and Olea. The concepts on Genus presented in Grana can also apply to other research fields, including Xanthium, Tricolpate, Asteroideae and Decalobanthus.

The most cited articles from the last journal are:

  • Recent developments in monitoring and modelling airborne pollen, a review (5 citations)
  • Spore characterisation and its taxonomic significance in ferns from Lagos State, Nigeria (2 citations)
  • Nypa pollen diversity in middle Eocene mangroves at the edge of the southern Proto-North Sea (Helmstedt, northern Germany) – a statistical approach (2 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.

The overall trend for top authors publishing in this journal is outlined below. The chart shows the number of publications at each edition of the journal for top authors.

Only papers with recognized affiliations are considered

The top affiliations publishing in Grana (based on the number of publications) are:

The overall trend for top affiliations publishing in this journal is outlined below. The chart shows the number of publications at each edition of the journal for top affiliations.

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, 12.20% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 11.11% were posted by at least one author from the top 10 institutions publishing in the journal. Another 11.11% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 30.56% of all publications and 47.22% 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.
