Special Issue Information

Dear Colleagues,

Understanding diversity patterns and how they are affected by global change are topics of active discussion in biodiversity research. In response to species declines, it is important to understand patterns of diversity and develop a knowledge base for use in species conservation. We still do not know, for example, the abiotic and biotic requirements for population persistence for most species.

Given the increasing threats to orchids globally, in this Special Issue, we concentrate on the orchid family because it has a large number of species and more than 50% of these species have been assessed to fall into one or more risk categories. Given the large number of orchid species, relatively few have been studied in detail. As a result, it is difficult to determine the best approach for conserving species and this Special Issue aims to fill in some of these gaps in our knowledge. To achieve this, we welcome a range of contributions on themes including, but not limited to, the following:

  • Orchid species distribution models.
  • Orchid population dynamics and their effects on orchid diversity.
  • Orchid conservation measures and an evaluation or their true effect on orchid diversity.
  • Orchid diversity in individual regions/countries and its association with particularities of these regions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Diversity is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • Reprint: MDPI Books provides the opportunity to republish successful Special Issues in book format, both online and in print.

Orchids play an important role in nature conservation and are often used for monitoring purposes. However, interpreting orchid monitoring data can be challenging for several reasons. We present here the first monitoring data of Orchis mascula subsp. speciosa from the Bohemian Waldviertel region in Austria, where this taxon is ‘endangered’. The data show a successful spread into mesotrophic grassland, which was historically arable land, and afterwards strong population fluctuations. Within ten years, the population has grown from 50 flowering individuals to more than 800. Over the next 20 years, the population fluctuated between fewer than 200 and more than 1800 flowering individuals. We discuss these observations against the background of land use changes and different management measures (i.e., ploughing, grazing, mowing, and sowing of grassland species). Furthermore, we more generally discuss the potential of European terrestrial orchids to act as ‘pioneers’ and to successfully establish in fallow land. Finally, monitoring data for Orchis mascula from six countries was compiled and interpreted, given the various biological characteristics of orchid species. Reviewed data showed complex, multifaceted patterns, which still do not allow generalized conclusions explaining population dynamics. Full article
