Special Issue Information

Dear Colleagues,

Global climate change is rapidly propelling many plant species to the brink of extinction. Global and regional strategies for biodiversity conservation indicate that risk assessment procedures are a crucial step for planning actions aiming to reduce future biodiversity loss. Accordingly, conservation biologists and conservation practitioners are devoting an increasing amount of effort to assessing the extinction risk met by wild species, in order to highlight the taxa of priority for conservation measures. Nonetheless, some aspects of the relationships among plant traits, threats, and extinction risk remain little understood. This Special Issue on “Extinction Risk and Threats to Plants” provides an opportunity to address the biological and ecological bases of plant responses to threats to improve current knowledge around the processes increasing extinction risk in plant species. Therefore, examples of optimal candidates for the SI include (but are not limited to) cross-taxon analyses of extinction risk integrating one or multiple threat effects, analyses of extinction risk incorporating species functional responses to threat factors, and functional studies illustrating measures for reducing current levels of extinction risk versus components of Global Change.

We expect this SI to substantially contribute to disseminating research outcomes that can increase our understanding of the conservation dynamics affecting plants in nature by favoring the implementation of more effective restoration actions.

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. 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.

Climate change poses a novel threat to biodiversity that urgently requires the development of adequate conservation strategies. Living organisms respond to environmental change by migrating to locations where their ecological niche is preserved or by adapting to the new environment. While the first response has been used to develop, discuss and implement the strategy of assisted migration, facilitated adaptation is only beginning to be considered as a potential approach. Here, we present a review of the conceptual framework for facilitated adaptation, integrating advances and methodologies from different disciplines. Briefly, facilitated adaptation involves a population reinforcement that introduces beneficial alleles to enable the evolutionary adaptation of a focal population to pressing environmental conditions. To this purpose, we propose two methodological approaches. The first one (called pre-existing adaptation approach) is based on using pre-adapted genotypes existing in the focal population, in other populations, or even in closely related species. The second approach (called de novo adaptation approach) aims to generate new pre-adapted genotypes from the diversity present in the species through artificial selection. For each approach, we present a stage-by-stage procedure, with some techniques that can be used for its implementation. The associated risks and difficulties of each approach are also discussed.
