Special Issue Information

Dear Colleagues,

We are launching the Special Issue “Biogeography and Macroecology Hotspots in 2024” to celebrate advances in our discipline for the coming year. This Special Issue is dedicated to high-quality review papers and research papers on all aspects of Biogeography and Macroecology. We welcome contributions from researchers who can offer insights on the latest developments in this field. We also encourage authors to invite relevant experts and colleagues to contribute to this Special Issue.

Prof. Dr. Michel Baguette
Guest Editor

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 100 words) can be sent to the Editorial Office for announcement on this website.

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.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Climate change will have various impacts on the survival and development of species, and it is important to explore whether plants can adapt to future climate conditions. Dipteronia dyeriana is an endangered species with a narrow distribution in Yunnan, characterized by a small population size. However, studies on its current distribution and the impact of climate change on its future survival and distribution are very limited. In this study, the current and future (2050 and 2090) potential habitats under the SSP1-2.6, SSP3-7.0, and SSP5-8.5 scenarios were predicted using both maximum entropy (MaxEnt) and random forest (RF) models based on the current range points of D. dyeriana, soil, topographical, land cover, and climate data. The results showed that the RF model demonstrated significantly higher AUC, TSS, and Kappa scores than the MaxEnt model, suggesting high accuracy of the RF model. Isothermality (bio_3), minimum temperature of the coldest month (bio_6), and annual precipitation (bio_12) are the main environmental factors affecting the distribution of D. dyeriana. At present, the high suitability area of D. dyeriana is mainly concentrated in the eastern part of Yunnan Province and part of southern Tibet, covering an area of 3.53 × 104 km2. Under future climate change scenarios, the total area suitable for D. dyeriana is expected to increase. Although, the highly suitable area has a tendency to decrease. With regards to land use, more than 77.53% of the suitable land area (29.67 × 104 km2) could be used for D. dyeriana planting under different SSP scenarios. In 2090, the centroid shifts of the two models exhibit a consistent trend. Under the SSP1-2.6 scenario, the centroids transfer to the southeast. However, under the SSP3-7.0 and SSP5-8.5 scenarios, the centroids of high suitability areas migrate toward the northwest. In summary, this study enhances our understanding of the influence of climate change on the geographic range of D. dyeriana and provides essential theoretical backing for efforts in its conservation and cultivation.

Halimium, Cistaceae, is a genus of shrubs restricted to the western part of the Mediterranean basin, where it thrives in diverse habitats. Despite this ecological adaptability, little attention has been devoted to understanding the mycorrhizal biology of Halimium. Through the examination of both sporocarps and ectomycorrhizal root tip collections, together with a thorough study of data previously reported in the relevant literature, we revealed a rich diversity of ectomycorrhizal mycobiota associated with Halimium spp. In this study, we describe the noteworthy diversity of the basidiomycetous family Inocybaceae in Halimium stands. Some 17 species of Inocybe and Pseudosperma are currently reported as linked to Halimium spp., mostly on the basis of sporocarp occurrence in the proximity of the potential host plant. Of these species, over 40% (7 of 17) come from our own study based on observations in pure Halimium stands in southwestern Sardinia, Italy. We also describe two new species of Inocybe, I. halimiphila sp. nov. and Inocybe rupribes sp. nov., that were collected under Halimium and demonstrated to establish ectomycorrhizal symbiosis with the shrub. We discuss the main morphological and ecological characteristics that distinguish the new species, unveiling their evolutionary relationships by inferring a phylogeny based on multiple loci.
