Za uredništvo / For the editorial board Katarina Cufar, Jože Kropivšek 
Ta številka revije Les/Wood je posebna iz vec ra­zlogov. Vecji del aktivnosti z njenim nastajanjem je bil namrec izveden v casu zapore inštitucij zaradi pande­mije korona virusa Covid19, kar je za naše avtorice in avtorje, recenzentke in recenzente ter uredniški odbor predstavljalo svojevrsten izziv. Ne glede na to pa so se reviji oz. njenemu uredniškemu odboru pridružili ugled­ni znanstveniki iz tujine. Med njimi so prof. dr. Manue­la Romagnoli, Department of Innovation of Biological Systems, Food and Forestry DIBAF, Tuscia University, Viterbo, Italija, prof. dr. Denis Jelacic, Šumarski fakultet, Sveucilište u Zagrebu, Hrvaška, dr. Krishna K. Pandey, In­stitute of Wood Science & Technology, Indian Council of Forestry Research and Education, Bangalore, Indija, in dr. Alan Crivellaro, Department of Geography, Universi­ty of Cambridge, Velika Britanija. Zelo smo veseli, da so sprejeli naše povabilo, obetamo si dobro sodelovanje. Za mednarodno prepoznavnost revije Les/Wood je to ned­vomno zelo pomembno. 
V tokratni številki revije objavljamo sedem znan­stvenih clankov, od tega so štirje v anglešcini. Posebej nas veseli, da je med avtoricami in avtorji spet veliko novih imen. Tokrat bi radi predstavili mlade avtorice in avtorja. Dva sta pridobila prestižne projekte, dve pa sta na zacetku doktorskega študija in sta tokrat prvic objavili clanek v znanstveni reviji. 
Dr. Kavyashree Srinivasa iz Indije je pridobila pro-jekt (NewSiest-867451) v okviru raziskovalno inovacij­skega programa EU H2020, MSC-IF = Marie Sklodowska--Curie – Individual Fellowships, kar dokazuje izjemno odlicnost njene raziskovalne poti. V okviru tega projekta, ki traja 2 leti, je trenutno zaposlena na Oddelku za lesar­stvo, Biotehniške fakultete, Univerze v Ljubljani, kjer pod mentorstvom prof. dr. Marka Petrica izvaja poglobljene podoktorske raziskave. Zakljucila je magisterij iz kemije in doktorirala na Inštitutu za lesarstvo (Institute of Wood Science & Technology) v kraju Bangalore (FRI DU, Dehra-dun) v Indiji. Leta 2013 je prejela nagrado Ron Cockcroft, ki jo podeljuje Mednarodna raziskovalna skupina za zaš-cito lesa (IRG-WP). 
Dr. Arnaud Maxime Cheumani Yona prihaja iz Kame­runa in je pridobil projekt „SilWoodCoat“, ki nosi »Pecat odlicnosti« in je financiran s strani ARRS, kar dokazuje raziskovalno odlicnost projekta in kandidata, ki se je tudi zaposlil na Oddelku za lesarstvo, Biotehniške fakultete, kjer pod mentorstvom prof. dr. Marka Petrica razvija pre-maze za les na osnovi silikatov. Po osnovni izobrazbi je kemik, njegovo raziskovalno delo pa vkljucuje predvsem lesarstvo, polimere in polimerne kompozite. Doktoriral je leta 2009 na Univerzi v Bordeauxu-Francija in je do­cent na Univerzi Yaoundé 1, v kraju Yaoundé, Kamerun. Pred tem je delal na vec raziskovalnih projektih, kjer se je ukvarjal z lesno-cementnimi kompoziti, utekocinje­nim lesom, razvojem premazov za les, modifikacijo lesa s poli(mlecno kislino) in s kompoziti iz naravnih vlaknen polimerov.
Nina Škrk je od jeseni 2019 mlada raziskovalka v okviru programa MR+ na Oddelku za lesarstvo Bioteh­niške fakultete Univerze v Ljubljani pod mentorstvom prof. dr. Katarine Cufar. Vpisana je na doktorski študij Bioznanosti, Les in biokompoziti. Njeno delo je usmerje-no v raziskave dreves in lesa z vidika posledic sprememb klime v 21. stoletju, ki so zabeležene v zgradbi lesa. To je njena prva objava znanstvenega clanka v reviji. 
Irena Sochová je od novembra 2019 doktorska štu­dentka na Univerzi Mendel v Brnu, Republika Ceška, na programu Predelava in tehnologije lesa s poudarkom na dendrokronologiji. Tema njene disertacije je sestava standardne kronologije širin branik hrasta za dendro-ar­heološke analize na obmocju Zahodne Ukrajine. Trenu­tno je zaposlena tudi na inštitutu CAS, Global Change Research Institute na Ceškem. To je njena prva objava znanstvenega clanka v reviji. 
Posebnost te številke revije je tudi to, da prvic uva­jamo prakso vodilnih znanstvenih revij v svetu glede od­prtega dostopa do raziskovalnih podatkov, ki so podlaga (empiricnim) znanstvenim clankom. Vkljucili smo se v aktivnosti RDA (Research Data Alliance) vozlišca Sloveni­je, ki ga s podporo projekta RDA EU 4.0 koordinira Arhiv družboslovnih podatkov. Tako enega izmed clankov v tej številki revije (Škrk et al., 2020) spremlja objava znan­stvenih podatkov (fotografij), ki so na ta nacin prosto do-stopni preko Repozitorija Univerze v Ljubljani (RUL). Pri objavi podatkov so nas vodili dr. Mojca Kotar (Univerzite­tna služba za knjižnicno dejavnost, Univerza v Ljubljani), doc. dr. Janez Štebe (Fakulteta za družbene vede, Uni­verza v Ljubljani), doc. dr. Sebastian Dahle (Oddelek za lesarstvo, Biotehniška fakulteta, Univerza v Ljubljani) in Darja Vranjek (INDOK, Oddelek za lesarstvo, Biotehniška fakulteta, Univerza v Ljubljani). Vsem lepa hvala. 

Posebej se zahvaljujemo vsem recenzentkam in re-cenzentom revije Les/Wood, ki so spet opravili odlicno delo v praviloma zelo kratkem casu. Zahvaljujemo se tudi ekipi, ki skrbi za tehnicno podporo revije, lektorja Paul Steed in Darja Vranjek, bibliotekarka Maja Valic, tehnicni urednik Anton Zupancic in oblikovalci iz podjetja DECOP d.o.o., Železniki. 
This issue of the journal Les/Wood is special for sev­eral reasons. Most of the related activities were carried out during the Covid-19 lockdown, which was very chal­lenging for our authors, reviewers and editorial board. However, despite all the inconveniences caused by the pandemic, four eminent scholars from abroad joined the journal and its editorial board. Among them are: Prof. Manuela Romagnoli, PhD, Department of Innovation of Biological Systems, Food and Forestry DIBAF, Tuscia Uni­versity, Viterbo, Italy; Prof. Denis Jelacic, PhD, Faculty of Forestry, University of Zagreb, Croatia; Krishna K. Pand­ey, PhD., Institute of Wood Science & Technology, Indian Council of Forestry Research and Education, Bangalore, India; and Alan Crivellaro, PhD, Department of Geogra­phy, University of Cambridge, UK. We are glad that they accepted our invitation, and we hope for fruitful further cooperation, which is undoubtedly very important for the international recognition of the journal. 
In this issue we are publishing seven scientific arti­cles, four of them in English. We are especially pleased that there are new names among the authors, and young authors in particular. Two of them have already acquired prestigious projects, while another two are at the beginning of their PhD studies and publishing arti­cles in a scientific journal for the first time. 
Kavyashree Srinivasa, PhD from India has obtained a project (NewSiest-867451) under the EU research in­novation programme H2020, MSC-IF (Marie Sklodows­ka-Curie – Individual Fellowship), which proves the excel­lence of her research. As part of the two-year project, she is currently employed at the Department of Wood Science and Technology, Biotechnical Faculty, University of Ljubljana, pursuing detailed post-doctoral research un­der the mentorship of Prof. Marko Petric, PhD. She com­pleted a master’s degree in chemistry and obtained her PhD from the Institute of Wood Science & Technology in Bangalore (FRI DU, Dehradun), India. She was a recipient of the Ron Cockcroft award from the International Re­search Group on Wood Conservation (IRG-WP) in 2013. 
Arnaud Maxime Cheumani, PhD from Cameroon has acquired the project “SilWoodCoat”, which bears the “Seal of Excellence” and is funded by the ARRS, a testament to the outstanding nature of both the re­searcher and the project. He currently works at the De­partment of Wood Science and Technology, Biotechnical Faculty, University of Ljubljana under the mentorship of Prof. Marko Petric, PhD., developing silicate-based wood coatings. He is a chemist by basic education, but in his research focusses mainly on polymers and polymer com­posites connected to wood science. He obtained his PhD from the University of Bordeaux-France in 2009, and is an assistant professor at the University of Yaoundé 1 in Yaoundé in Cameroon. Prior to this he worked on sev­eral research projects dealing with wood-cement com­posites, liquefied wood, development of wood coatings, wood modification with poly (lactic acid) and compos­ites made of natural polymer fibres. 
Nina Škrk has been working as a young researcher under the mentorship of Prof. Katarina Cufar, PhD at the Department of Wood Science and Technology, Biotech-nical Faculty, University of Ljubljana since the autumn of 2019. She is enrolled in the PhD study of Biosciences, Wood and Biocomposites. In her research she focuses on the effects of climate change in the 21st century on trees and wood. This is her first publication of a scientific article in a scientific journal. 
Irena Sochová has been a PhD student at Mendel University in Brno, Czech Republic since November 2019. She works within the Wood Processing and Timber Tech­nology programme with a focus on dendrochronology. The main topic of her dissertation is the oak tree-ring standard chronology as a tool for dendro-archaeological analyses in the Western Ukraine. Currently she is also employed at CAS, the Global Change Research Institute in the Czech Republic. This is her first publication of a scientific article in a scientific journal. 
The main feature of this issue is the introduction of the practice of the world’s leading scientific journals regarding open access of their research data, which is basis for (empirical) scientific articles. We joined the ac­tivities of the RDA (Research Data Alliance) of the Slo­venian hub, which is coordinated by the Social Science Data Archive with the support of the RDA EU 4.0 pro­ject. Thus, one of the articles in this issue (Škrk et al., 2020) is accompanied by the publication of the scientific data (photographs), which are freely available through the Repository of the University of Ljubljana (RUL). In publishing the data we were guided by Mojca Kotar, PhD from University Library Services, University of Ljubljana, Janez Štrebe, PhD from the Faculty of Social Science, University of Ljubljana, by Sebastian Dahle, PhD from Department of Wood Science and Technology, Univer­sity of Ljubljana, and by Darja Vranjek from INDOK, De­partment of Wood Science and Technology, Biotechnical Faculty, University of Ljubljana. Thank you all for your work, we truly appreciate your efforts. 
Special thanks go to all the reviewers of the Les/ Wood journal, who did excellent job once again in a very short time. In addition, we would like to thank the tech­nical support team, proof-readers Paul Steed and Darja Vranjek, librarian Maja Valic, technical editor Anton Zu­pancic and designers from DECOP d.o.o., Železniki.
