Ozone Impacts on Forests

Dear Colleagues,

Air pollution and climate change are identified as major issues affecting European society. Tree species can respond differently to climate change and air pollution, depending on several tree features, such as morphological, physiological, and chemical functional traits of leaves (linked to the plants functioning), phenotypic plasticity (changes in morphology and physiology), plant phenology, as well as environmental conditions. Furthermore, several biotic and abiotic stressors in various geographic areas are involved in the intra-specific selection of plants that survive environmental stress by stress avoidance or tolerance. Tropospheric ozone (O₃) is, by far, the most widespread and harmful pollutant to trees, and its concentrations have been increasing in the Northern Hemisphere since the pre-industrial era. The ability to avoid (stomatal regulation) and/or turn on tolerance mechanisms (activation of scavenging mechanisms) is diverse and specific among plant species, and it characterizes the response to O₃ oxidative stress. Different provenances might respond differently to O₃. We encourage studies from all fields, including experimental studies, monitoring observations, and modeling approaches to contribute to this Special Issue in order to promote knowledge for the identification of spatial and temporal behaviors in forests responses to O₃ oxidative stress.

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. Forests 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 2600 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.
