Special Issue Information

Dear Colleagues,

One of the most challenging and dangerous manifestations of climate change are extreme climatic events (ECE). Based on IPCC reports, the frequency and intensity of certain extreme weather conditions, such as droughts, heat waves, heavy precipitation, and floods, are projected to increase throughout this century. These events are particularly dangerous for the agricultural sector, reducing the yield and quality of crops and forage grasses. A shift in the biodiversity of natural plant communities is also a growing problem, induced by climate change. Gaps of knowledge exist in the mechanistic understanding of combined or subsequent effects of ECEs on plants and their interaction with pests, the soil microbial community, and competing species.  Investigations at different levels, e.g., interplay between plant, community, and ecosystem, cycling of carbon and nutrients, and ecosystem functioning and services, are extremely important.

The aim of this Special Issue on “Plant Responses to Climate Extremes” in Plants is to induce and maintain the discussion within the scientific community of plant ecologists and physiologists about new, relevant, and undiscovered manifestations of ECE effects on pants. It covers a broad scope of topics, including, but not limited to the direct and indirect effects of ECEs on plants, an interplay between ECEs and its complex effects on plants, the mechanism of plants’ adaptation and potential to recover, etc. A wide range of target species are welcome: crops, forage plants, water and wetland plants, herbs, trees, and endangered or invasive species. Scientific, relevant, and original research or reviews can be focused on different organization levels of life, ranging from organelles to the whole ecosystem.

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. Plants is an international peer-reviewed open access semimonthly 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 2700 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.

Pilocarpus microphyllus Stapf. ex Wardlew. (Rutaceae) is an endemic and threatened medicinal plant species from tropical Brazil. Popularly known as “jaborandi”, it is the unique natural source of pilocarpine, an alkaloid used to medical treat glaucoma and xerostomia. Based on Species Distribution Models (SDMs), we modeled the suitability of P. microphyllus’s geographical distribution considering three Global Circulation Models (GCMs) under two future climate change scenarios (SSP2-4.5 and SSP5-8.5). The quantitative analyses carried out using ten different SDM algorithms revealed that precipitation seasonality (Bio15) and precipitation of the driest month (Bio14) were the most important bioclimatic variables. The results evidenced four main key areas of continuous occurrence of the plant spreading diagonally over tropical Brazilian biomes (Amazon, Cerrado and Caatinga). The near-future (2020 to 2040) ensemble projections considering all GCMs and scenarios have indicated negative impacts for the potential loss or significant reduction in suitable habitats for P. microphyllus in the transition region between the Amazon and Cerrado into central and northern Maranhão state, and mainly in the Caatinga biome over the northern Piaui state. On the other hand, positive impacts of the expansion of the plant habitat suitability are projected over forest cover protected areas of the Amazon biome in the southeastern Pará state. Since the jaborandi is of socioeconomic importance for many families in the north/northeast Brazil, it is urgent to implement public policies for conservation and sustainable management, thus mitigating the impacts of global climate change.
