1. AIMS AND SCOPE

Forest Systems (FS) is a four-monthly international peer-reviewed journal. Forest Systems main aim is to integrate multidisciplinary research with forest management in complex systems with different social and ecological backgrounds. To fulfil this integrative approach, FS gives preference to papers that bring together two or more disciplines, organisms, or forest products and services. Studies of all kinds of forest systems are welcomed, particularly those that describe a wide variety of wood and non-wood products and ecosystem services, such as forests in regions with a Mediterranean climate. Forest Systems covers research findings on all aspects of forestry, such as genetics (including breeding), plant ecology, ecophysiology, paleoecology, dendroecology, silviculture (including biometrics), forest management, integrated fire management, forest conservation (plants and animals), forest soils and erosion, soil bioma (including fungi and mycorrhization), forest pathology, entomology and plagues, forest policy and economics, ecosystems services, agroforestry systems (including pastures and grazing),forest products (including non-wood) and wood technology, remote sensing and GIS advanced tools, data forests and software.

Descriptive bibliometric studies are not accepted. These technics are only accepted is results are well discussed and focused to forest topics.

2. MANUSCRIPT CATEGORIES

Forest Systems accepts the following manuscript categories:

Research articles make an original and significant contribution to the field of study within the scope of the journal. These articles should be of interest to a broad audience, scientifically sound, well written and concise.

Short communications should cover a concise study of wide interest, novelty and/or high quality. Papers must report relevant information, not preliminary findings. Articles with local-regional interest may only be accepted here or in the Resource Communications section.

Resource communications include all types of papers on resources or tools of interest for the study and management of forest systems (e.g., methodologies, software and growth models, open access databases). They must report a completed work, not preliminary findings.

Reviews or minireviews aim to provide an overview for an issue of great interest or topicality. They will be invited by the Editorial Board. However, potential authors can suggest topics to the Editor-in-Chief. Authors must have published some works earlier on the subject.

3. PLAGIARISM POLICY, PEER REVIEW AND EDITING

Upon submission, the Editor-in-Chief assesses the manuscript for suitability. Manuscripts may be rejected without peer review if they do not relate to the scope of the journal or if they do not conform to the submission rules. The submitted manuscript must not be under consideration for publication elsewhere and the work described has not been published previously in any language (except in a book of abstracts, in the proceedings of a scientific meeting or as part of a thesis). Through Similarity Check, we use the iThenticate software to detect instances of overlapping and similar text in submitted or published manuscripts.

All other articles are allocated to Associate Editors, depending on the topic. Associate Editors maintain a global vision of their topic areas. They select relevant referees (including members of the International Scientific Committee) for single-blind peer review (the referees know the identity of the authors, but the authors do not know the identity of the referees).

Two referees are usually invited to comment on each submission. When the opinions of the referees differ significantly, the manuscript is usually sent to a third referee. When a decision has been reached, the decision is communicated to the author.

The editors' decision is final unless there is a proven error in the process of manuscript evaluation or peer review. If you believe that there has been a process error in the handling of your manuscript, please address your concerns to the Forest Systems Editorial Office (forestsystems@inia.csic.es) and include the manuscript submission number.

COPYEDITING. After the author has submitted the final version and this has been accepted for publication, the manuscript undergoes a copyediting process. The copyeditor performs the clean-up edit. This edit occasionally generates new queries, which are sent to the author. FS reserves the right to correct grammar, improve clarity, and impose the FS style. Authors are responsible for content, including the spelling of personal and place names. FS reserves the right to refuse publication of articles that, upon repeated resubmission, do not meet stylistic standards. When copyediting is complete, the issue is produced.

4. OPEN ACCESS

See the Open Access Policy section.

5. ETHIC RESPONSIBILITIES

Previously published material is not accepted: Authors are held responsible for obtaining permission for reproduction of materials (text, tables, or figures) included in other publications, and for accurately quoting their origin. Authorization must be requested from the owner of the rights to this material.

When reporting experiments on animals, authors must indicate which institutional and national guide for the care and use of laboratory animals has been followed.

Conflicts of interest: A conflict of interest exists when professional judgment concerning a primary interest (such as the validity of research) may be influenced by a secondary interest (such as financial gain). Financial relationships (such as employment, consultancies, stock ownership, honoraria, paid expert testimony) are the most easily identifiable conflicts of interest. However, conflicts can occur for other reasons, such as personal relationships, academic competition, and intellectual passion. FS expects authors to declare any commercial involvements that may represent a conflict of interest in connection with their articles.

Authorship. Following the International Committee of Medical Journal Editors recommendations (http://www.icmje.org), authorship must be based on the following four criteria:

1. Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; AND
2. Drafting the work or revising it critically for important intellectual content; AND
3. Final approval of the version to be published; AND
4. Agreement to be accountable for all aspects of the work by ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.

In addition to being accountable for the parts of the work he or she has done, an author should be able to identify which co-authors are responsible for specific other parts of the work. Besides, authors should have confidence in the integrity of the contributions of their coauthors.

All those designated as authors should meet all four criteria for authorship, and all who meet the four criteria should be identified as authors. Those who do not meet all four criteria should be acknowledged.

It is the authors’ collective responsibility, not the journal to which the work is submitted, to determine that all people named as authors meet all four criteria.

The corresponding author is the one individual who takes primary responsibility for communication with the journal during the manuscript submission, peer review, and publication process and must be the same person that makes the submission. The corresponding author should be available throughout the submission, peer review and copyediting processes to answer to editorial queries in a timely way, and should be available after publication to respond to critiques of the work and cooperate with the journal editorial office regarding any requests for data or additional information about the paper that arise after publication.

6. SUBMISSION

Authors must submit manuscripts via the website of Forest Systems (https://fs.revistas.csic.es).

IMPORTANT!

• There are Microsoft Word templates available for preparing your manuscript (point 6.2) that we strongly recommend to use.
• Authors are required to check off their submission's compliance with all of the items indicated in the Submission Preparation Checklist.

 6.1. Submission process

The corresponding author is the person who has to submit the work at the system. This author may register on the site at any time, but he/she should register only once. During registration, the author chooses a username and password. The security of the manuscripts is protected by the username/password system.

The corresponding author must also fill in all the co-authors data, in step 3 of the submission process (List of contributors). It is mandatory to fill in the following fields: given name and family name, email, country (of professional activity), institutional affiliation, and Open Researcher and Contributor Identifier (ORCID). A submission will be automatically rejected if it does not comply with these requirements.

The corresponding author must use a single email address throughout the entire process: (i) when registering as an author in the system, (ii) in the list of contributors (metadata in the system) and (iii) in the word document of the article. In case the institutional e-mail address fails in certain instances, please include in the manuscript an alternative personal e-mail address besides this one.

You may find instructions to upload a manuscript under the site MAKE A SUBMISSION.

Please upload four documents:

1. The entire MANUSCRIPT, with tables, figures and supplementary files in Word format, on separate sheets but in the same document as a unique file. Separate figure files will be required later if the manuscript is accepted.
2. COVER LETTER: indicate the main aims of the manuscript, the type of paper (Research paper, Review paper, Short communication, Resource communication), the novelty of the content, and convincing arguments of why FS should publish this paper. In case of resubmission, a rebuttal letter indicating the reference number of the first submission.
3. A LIST OF FOUR POTENTIAL EXPERT REVIEWERS with full contact information and e-mail addresses. These reviewers must not have a conflict of interest with the authors (e.g. personal relationship or work in the same institution) or the paper content, and the Editorial Board may decline to contact any of the reviewers suggested by the authors.
4. The COPYRIGHT TRANSFER STATEMENT filled and signed by all authors.

Submission of a manuscript implies the following:

• The work described has not been published previously in any language (except in a book of abstracts, in the proceedings of a scientific meeting or as part of a thesis).
• The work is not under consideration for publication elsewhere.
• All persons named as authors critically reviewed the manuscript, approved the final version and consented to its publication.
• All persons named as authors in the manuscript must be coincident with the persons included in the List of Contributors when filling the metadata in the submission process.
• It is the authors’ collective responsibility, not the journal to which the work is submitted, to determine that all people named as authors meet the criteria described in the instructions for authors.
• The manuscript will not be published elsewhere in any language without the consent of the copyright holders.
• Written permission of the copyright holder was obtained by the authors for materials from other copyrighted sources.
• The language has been revised by a professional science editor or a native English-speaking colleague if there is any doubt about the clarity of the language, or English is not the mother tongue of the authors. FS reserves the right to require a professional certification of English language review.
• In case of resubmission, the reference of the initial submission is provided.

6.2. Manuscript preparation

Authors must use the Microsoft Word templates to prepare their manuscript.

Research articles should not be longer than 8,500 words, including front page, references, tables and figures, and excluding the supplementary material. Research articles should contain a front page, an abstract, up to seven keywords and the abbreviations used. The main text should have the following sections (see suggested layout below): introduction; material and methods; results; discussion (avoid combining the results and discussion sections); acknowledgments; authors’ contributions; up to 40 references; tables and figures; and supplementary material, if any. Research article template

Short communications and Resource communications should be no longer than 3,500 words, including front page, references, tables and figures, and excluding the supplementary material. Short communications should contain a front page, an abstract, up to seven keywords and the abbreviations used. The main text should include the following sections: introduction; material and methods; results and discussion combined sections; acknowledgments; authors’ contributions; up to 30 references; up to three tables and/or figures; and supplementary material, if any. Short communication template and Resource communication template

Review or minireview articles (typically invited by the Editor) should be no longer than 10,000 words, including front page, references, tables and figures, and excluding the supplementary material. They should include a front page (the manuscript title must contain the word "Review"); an abstract; up to seven keywords; abbreviations used; a variable main text (the introduction should be based on general coverage of the issue, followed by a critical assessment of the most important references); acknowledgments; authors’ contributions; up to 80 references; tables/figures (encouraged); and supplementary material, if any. Reviews will also be submitted to the peer-review process. Review article template

Language: Manuscripts should be written in concise, legible English, which must be carefully reviewed by the authors for correctness of language and content. English spelling can be British or American, but it must be consistent throughout. Authors whose first language is not English are strongly advised to have their manuscripts checked by a proficient third party prior to submission. Title, abstract and keywords will also be provided in Spanish.

Papers reporting sequence data. Manuscripts containing primary nucleotide sequence data must be accompanied by (an) accession number(s) from an internationally available nucleotide database.

Papers reporting software. Software should be available for a period of two years after publication of the manuscript.

Papers reporting field research. Field research should indicate replications in sites and years in connexion to the addressed aims of the experiment(s). In many cases, several years may be required to account for all variations in factors that affect plant growth and development, in particular for those researches dealing with production and yield. Since the lack of this requirement can be cause of manuscript rejection during the preliminary inspection, if this recommendation is not fulfilled, arguments supporting the validity of the results must be stated and included in the letter addressed to the Editorial Office.

 6.3. Layout

The following layout is strongly recommended. Please see the template (point 6.2):

6.3.1. Front page

Special attention should be paid to the title and abstract, as these will influence readers’ decisions to proceed with the text. The first page must include the following:

• Type of the paper.
• Title in English and Spanish.
• Authors´ names.
• Authors´ ORCID ID.
• Affiliations.
• Corresponding author´s name and e-mail address.
• Running title.
  
• Topic.
• Number of tables and figures.
• Abstract in English and Spanish.
• Additional key words in English and Spanish.

 6.3.2. Text of the article

The text of the Research articles, Short communications and Resource communications should contain the following sections listed in the order:

• Introduction
• Material and methods
• Results *
• Discussion *
• Acknowledgements
• Authors´contributions
• References
• Tables and/or figures
• Supplementary material (data that do not appear in the paper itself but that accompany it online), either figures or tables, should be included in the article itself, on separate sheets but in the same unique document. These data are peer reviewed, must be cited in the text and are subject to the same criteria as the data published in the paper.

* In Short communications and Resource communications, Results and Discussion sections must be combined in a single section.

The text of the Review articles should contain the following sections listed in the order:

• Introduction
• Titles and Subtitles regarding literature review
• Conclusions and future perspectives
• Acknowledgements
• Authors´contributions
• References
• Tables and/or figures
• Supplementary material (data that do not appear in the paper itself but that accompany it online), either figures or tables, should be included in the article itself, on separate sheets but in the same unique document. These data are peer reviewed, must be cited in the text and are subject to the same criteria as the data published in the paper.

6.4. Revised manuscripts

Once the editorial decision is sent to the authors, they are required to submit their revised manuscripts highlighting the changes by using the option “Track Changes” in the Microsoft word file and accompanied by a letter containing a detailed (point-by-point) reply to the reviewers and editor’s comments. A revised manuscript will retain its original date of receipt only if it is received within two months of the date of return to the author. Revised papers returned after this interval will be archived and treated as new submissions. Papers will not be accepted until all required changes have been incorporated into the document.

7. STYLE

Units and symbols. Use SI (International System) units in accordance with the recommendations of the International Organisation for Standardisation (ISO) or the Bureau for Poids et Mesures (BIPM) (https://www.bipm.org/en/publications/si-brochure).

Use abbreviations L, mL and µL for capacity or volume units. Express N (normality) as mmol/L and ppm as mg/kg or mg/L. Please spell out numbers one through nine, except when used with units. When units are not preceded by a number, the term should be written in full, without using the symbol (e.g., “metres”, “23 m”). Express decimals using a full stop (e.g., 3.14) and thousands with commas (e.g., 21,314). For decimal quantities <1, place a zero before the decimal point. Report dates with the day first, then the month, and then the year.

Abbreviations must be defined when first mentioned in the abstract or text [e.g., “polymerase chain reaction (PCR)”] and again in the tables and figures. Abbreviations must then be used throughout the article, except at the beginning of a sentence.

Style must be that of scientific English throughout the article. Please ensure that a science editor reviews the paper before submitting it for publication.

Mathematical equations. Use an equation editor for mathematical expressions whenever possible. Avoid inserting equations as images.

Parameters. It is a common mistake to use the term “parameters” instead of “variables” or “characters”. Variables are quantities that vary from individual to individual (e.g., length, width). By contrast, parameters do not relate to actual measurements or attributes, but to quantities that define a theoretical model; they are properties of a collection of individuals (e.g., mean and SD). In other words, you measure a variable; a parameter describes the measurements, such as the mean.

Never start sentences with a numeral: “Four plants and five years ago” is correct, not “4 plants and 5 years ago”. This means that some sentences may need to be rewritten: “Farmers collected 4,000 fruits the first year” instead of “4,000 fruits were collected the first year.”

Scientific names. Genus must be written in full the first time an organism is mentioned in the abstract or text and in every table and figure. If you are discussing several different species within a genus so that the genus is the same for each species mentioned, write genus + species in full the first time each new species is mentioned, even if it seems redundant. After the first time, use the genus abbreviation with a period.

Genus and species are always italicised. Do not italicise "spp.", "sensu stricto" or "sensu lato", which may follow genus and species. Genus is italicised when it appears alone (i.e., Phytophthora infections).

Latin binomials or trinomials and authorities, when first mentioned, must be given for all plants, insects and pathogens (e.g., Solanum lycopersicum L.).

Both common and chemical names of pesticides must be given when first mentioned (e.g., “Atrazine (2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine) was most persistent...”).

Identify soils at series and family level, or at least the Great Group, when first mentioned.

Mark botanical cultivars in single inverted quotation marks, or use the abbreviation cv. when first mentioned (e.g., tomato ˈRoyestaˈ or cv. Royesta). Subsequently, this can be referred to as Royesta tomato or Royesta cultivar.

Animals (breed, sex, age, and body weight), diets, measurements and statistical models should be written in a clear and detailed way.

Statistical results. In-line statistical results should be presented as: (i) the test statistic followed by degrees of freedom as subscript(s), e.g., F1,12=1.74 or t8=31.8; (ii) followed by the p-value, or NS (for non-significant), e.g., F1,12=1.74, p>0.05. In tables, statistical results should be comprehensive, facilitating future meta-analyses. Depending on the details of the analyses, the results reported may include parameter estimates, test statistics, degree of freedom, significance levels and error/residual model information, e.g., error MS and d.f. in ANOVA or regression models. Because exact p-values can be useful for meta-analyses, we recommend that these be quoted even when non-significant, e.g., t23=0.25, p=0.34, or F2,32=1.12, p=0.55. However, non-significant tests (i.e., p>0.05) should always be interpreted as such and not reported.

8. CORRECTION OF PROOFS

Page proofs of articles are sent to authors by email as PDF files. Corrected proofs (by means of the Acrobat system) should be sent back to the Editorial Office within three days by email. Proofreading occasionally generates additional queries for the author. If corrections are not received in due time, the editors reserve the right to perform the corrections that they consider most appropriate.

The articles are published in three formats: PDF, HTML and XML. Due to the difficulty to correct the three types of proofs, authors are asked to check only for misprints or syntactic errors but not to modify the manuscript.

9. FOREST SYSTEMS POLICY ON ARTICLE WITHDRAWAL

Articles that have been published shall remain extant, exact and unaltered as far as possible. However, very occasionally circumstances may arise where an article is published that must later be retracted or even removed. Such actions can only occur under exceptional circumstances, such as:

Article retraction: Only used for articles which represent infringements of professional ethical codes, such as multiple submission, bogus claims of authorship, plagiarism, and fraudulent use of data or the like. A retraction note titled “Retraction: [article title]” signed by the authors and/or the editor is published in the paginated part of a subsequent issue of the journal and listed in the contents list. In the electronic version, a link is made to the original article. The online article is preceded by a screen containing the retraction note. It is to this screen that the link resolves; the reader can then proceed to the article itself. The original article is retained unchanged except for a watermark on the PDF indicating on each page that it is “retracted.”

Article replacement:In cases where due to unintentional error, or the article, if acted upon, might pose a serious health risk, the authors of the original article may wish to retract the flawed original and replace it with a corrected version. In these circumstances the procedures for retraction will be:

1. The original article is retained unchanged (same doi) except: 1, in the title “Article replaced” will be added at its end; 2, in the article metadata, the link to the new doi will be included at the end of the Abstract; 3, a watermark on the PDF will indicate on each page “ARTICLE REPLACED”; 4, a first page will be added to the pdf with the history.
2. A new pdf file will be prepared (new submission, new doi). The first page will have a footnote with the history (This article replaces the article with the same title (xxx) that has been published in xxx. The reason for its replacement is …).

Article removal: In an extremely limited number of cases, it may be necessary to remove an article from the online database. This will only occur where the article is clearly defamatory, or infringes others’ legal rights, or when the article is, or we have a good reason to expect it will be, the subject of a court order, or when the article, if acted upon, might pose a serious health risk. In these circumstances, while the metadata (title and authors) will be retained, the text will be replaced with a screen indicating the article has been removed for legal reasons.

3.- As you will see on the new submissions page, submitting a manuscript is a four-stage process, in addition to a final section with information on follow-up:

3.1.- "1. Start"

At this stage you must select the language in which the article is written and the section of the journal in which you think it would fit, you must indicate that you have prepared all the items on the "Submission requirements" list and, optionally, you may send comments to the editor. You must comply with the terms of the Copyright Statement and the collection and storage of your data as the author of the article in accordance with the Privacy Statement of the Consejo Superior de Investigaciones Científicas (CSIC).

Then press the "Save and continue" button.

3.2.- "2. Upload submission"

In this phase, the files that make up the article and its additional documentation will be uploaded to the management module.

There are three parts to upload each file. In the first one, we will select which component of the article we are going to contribute and we will upload the corresponding file. Once uploaded, click on the "Continue" button. In the second part we will see the file metadata, with the possibility to edit them, but we will click "Continue" without making this edition.

In the third part, select "Add Another File", going back to "1. Upload file" and, without modifying the default option "This is not a revision of an existing file", select the new "Article Component" identifying what it is and uploading the file. Click "Continue" until you reach, once again, step "3. Confirm". This process must be repeated until all the files have been sent, and only when all the material has been uploaded should the "Complete" button be selected.

If after "Completing" the submission we realise that we have forgotten to upload a file, we can do so by selecting the "Upload File" button located in the upper right-hand corner of the "2. Upload Submission" tab:

Once all the submission files have been uploaded, we will press the "Save and continue" button.

3.3.- "3. Enter Metadata"

In this phase the author will enter the metadata of the article according to the journal guidelines. These are:

- Title in Spanish and English. If the article is written in another language, it will be introduced first this language and then in English.

- Summary or abstract in the same languages as the previous item.

- List of contributors. Although it was not necessary when registering as a journal user, in this section it is compulsory for authors to have their ORCID identifier and affiliation correctly indicated. If necessary, the information of additional authors will be added using the link "Add contributor":

- Keywords. The article keywords will be inserted in both languages. The entire list cannot be copied, must be entered one term at a time pressing "Enter" after each one.

- Funding data. The entities that have supported the research published in the article must be indicated. After selecting "Add funder", the name of the funder should be inserted again, which will trigger an internal search that will return the institution standardised name and DOI. If the institution does not have a DOI, it will not be able to register in this field. After entering the grant numbers, click on "Save".

To finish this phase of entering metadata, click on the "Save and continue" button.

3.4.- "4. Confirmation" y "5. Next steps"

In this last phase we will confirm the submission metadata recording linked to the uploaded files. Before clicking on the "Finish Submission" button, we can go back to the previous phases and review the information and files provided to check that they are all correct.

Once we click on the "Finish Submission" button, the article will be sent to the journal and its staff will contact you to continue with the process, as indicated in the "5. Next Steps" section.

How to check a revision report and submit a revised version of a manuscript

Once your submission has been reviewed, the journal's staff will send you a review report. Once received, you must log in to the journal and, in the "Submissions" section of your dashboard, you will be able to check that your submission is in the Review phase and, if the editorial staff has requested, whether it is necessary to make any modifications or revisions to the manuscript:

By clicking on the title of your submission, you will be taken to the workflow of your submission and you will be able to check the information related to the its review. You will find the notifications that the editorial staff has sent you, the attachments that the reviewers may have attached and, if requested, the possibility to provide a new version of the manuscript with the requested modifications by clicking on the "Upload file" button:

Research data policy

We recommend authors depositing data obtained from the research developed for the preparation of their article in repositories of recognized prestige, specific to the discipline or of a generalist nature. In any case, it must be a FAIR repository (Findable, Accessible, Interoperable, Reusable), preferably in open access.

There are several repositories destined to conserve and disseminate concrete data such as results of surveys, observations, interviews, simulations, automatically collected data, samples, models ... If necessary, authors can consult the Registry of Research Data Repositories re3data taking into account that each repository has its own deposit rules.

Those CSIC authors who would like to deposit their datasets in Digital.CSIC may do so by following these guidelines. They can use the Servicio de Archivo Delegado made available by the Technical Office of DIGITAL.CSIC and the Red de Bibliotecas CSIC.

DIGITAL.CSIC generates DOIs for datasets and associated software and is certified as data repository in re3data and Repository Finder. More information at Política de datos en Digital.CSIC.

If the author has deposited datasets in a repository, he should mention it in the article providing a brief description of the type of data deposited, the name and URL of the repository, the identification code and the data of the license for use and distribution. This information must be included at the end of the article, immediately before the bibliographic listing, under the heading "Data availability".
