5. Marginality indices for biodiversity conservation in forest treesNicolas Picard, Maurizio Marchi, Maria Jesus Serra-Varela, Marjana Westergren, Stephen Cavers, Eduardo Notivol, Andrea Piotti, Paraskevi Alizoti, Michele Bozzano, Santiago C. González-Martínez, 2022, izvirni znanstveni članek Povzetek: Marginal and peripheral populations are important for biodiversity conservation. Their original situation in a species’ geographic and ecological space often confers them genetic diversity and traits of high adaptive value. Yet theoretical hypotheses related to marginality are difficult to test because of confounding factors that influence marginality, namely environment, geography, and history. There is an urgent need to develop metrics to disentangle these confounding factors. We designed nine quantitative indices of marginality and peripherality that define where margins lie within species distributions, from a geographical, an environmental and a historical perspective. Using the distribution maps of eight European forest tree species, we assessed whether these indices were idiosyncratic or whether they conveyed redundant information. Using a database on marginal and peripheral populations based on expert knowledge, we assessed the capacity of the indices to predict the marginality status of a population. There was no consistent pattern of correlation between indices across species, confirming that the indices conveyed different information related to the specific geometry of the species distributions. Contrasting with this heterogeneity of correlation patterns across species, the relative importance of the indices to predict the marginality status of populations was consistent across species. However, there was still a significant country effect in the marginality status, showing a variation in expert opinion of marginality vis-á-vis the species distribution. The marginality indices that we developed are entirely based on distribution maps and can be used for any species. They pave the way for testing hypotheses related to marginality and peripherality, with important implications in quantitative ecology, genetics, and biodiversity conservation.

6. Forest genetics research in the mediterranean basin : bibliometric analysis, knowledge gaps, and perspectivesBruno Fady, Edoardo Esposito, Khaled Abulaila, Jelena M. Aleksic, Ricardo Alía, Paraskevi Alizoti, Ecaterina-Nicoleta Apostol, Filipos Aravanopoulos, Dalibor Ballian, Magda Bou Dagher Kharrat, Hojka Kraigher, Marjana Westergren, 2022, izvirni znanstveni članek Povzetek: Purpose of Review Recognizing that in the context of global change, tree genetic diversity represents a crucial resource for future forest adaptation, we review and highlight the major forest genetics research achievements of the past decades in biodiversity-rich countries of the Mediterranean region. For this, we conducted a bibliometric analysis of the scientific literature spanning the past thirty years (1991–2020). Putting together the representative regionwide expertise of our co-authorship, we propose research perspectives for the next decade. Recent Findings Forest genetics research in Mediterranean countries is organized into three different scientific domains of unequal importance. The domain “Population diversity and Differentiation” related to over 62% of all publications of the period, the domain “Environmental conditions, growth and stress response” to almost 23%, and the domain “Phylogeography” to almost 15%. Citation rate was trending the opposite way, indicating a strong and sustained interest in phylogeography and a rising interest for genetics research related to climate change and drought resistance. The share of publications from Asia and Africa to the total within the Mediterranean increased significantly during the 30-year period analyzed, reaching just below 30% during the last decade. Summary Describing poorly known species and populations, including marginal populations, using the full potential of genomic methods, testing adaptation in common gardens, and modeling adaptive capacity to build reliable scenarios for forest management remain strategic research priorities. Delineating areas of high and low genetic diversity, for conservation and restoration, respectively, is needed. Joining forces between forest management and forest research, sharing data, experience, and knowledge within and among countries will have to progress significantly, e.g., to assess the potential of Mediterranean genetic resources as assisted migration material worldwide.

7. Non-native forest tree species in Europe : ǂthe ǂquestion of seed origin in afforestationParaskevi Alizoti, Jean-Charles Bastien, Debojyoti Chakraborty, Marcin Miroslav Klisz, Johan Kroon, Charalambos Neophytou, Silvio Schueler, Marcela van Loo, Marjana Westergren, Monika Konnert, Robert Brus, 2022, izvirni znanstveni članek Povzetek: Non-native forest tree species have been introduced in Europe since the 16th century, but only in the second half of the 20th century the significance of the seed source origin for their economic use was recognized, resulting in the establishment of numerous provenance trials at a national, regional, European and International level, as those led by IUFRO. Breeding programs have also been launched in the continent for the most economically important species. Aim of this work is the formulation of provenance recommendations for planting of five non-native tree species in Europe (Douglas fir, grand fir, Sitka spruce, lodgepole pine and black locust), based on the information obtained from twenty countries, in the frame of the EU FP-1403 NNEXT Cost Action. The survey revealed that official and non-official national recommendations, based on provenance research results, have been elaborated and followed at a different level and extend for the above five species, but only for Douglas fir recommendations exist in almost all the participating to the survey countries. The compilation of provenance recommendations across Europe for each species is presented in the current work. Besides the recommended introduced seed sources, European seed sources are also preferred for planting, due to ease of access and high availability of forest reproductive material. European breeding programs yielding genetic material of high productivity and quality constitute currently the seed source of choice for several species and countries. Consolidation of trial data obtained across countries will allow the joint analysis that is urgently needed to draw solid conclusions, and will facilitate the development of ‘Universal-Response-Functions’ for the species of interest, rendering possible the identification of the genetic material suitable for global change. New provenance trial series that will test seed sources from the entire climatic range of the species, established in sites falling within and outside the environmental envelopes of their natural ranges, are urgently needed to pinpoint and understand the species-specific climate constraints, as well as to correlate functional traits to the seed origin and the environmental conditions of the test sites, so that the selection of suitable forest reproductive material of non-native tree species in the face of climate change can be feasible.

8. Genetic aspects linked to production and use of forest reproductive material (FRM) : collecting scientific evidence for developing guidelines and decision support tools for effective FRM managementDušan Gömöry, Katri Himanen, Mari Mette Tollefsrud, Claes Uggla, Hojka Kraigher, Sandor Bordacs, Paraskevi Alizoti, Stuart A'Hara, Aline Frank, Gunnar Friis Proschowsky, Josef Frýdl, Thomas Geburek, Monique Guibert, Mladen Ivanković, Ana Jurše, Stuart Kennedy, Jan Kowalczyk, Heike Liesebach, Tiit Maaten, Andrej Pilipović, Roberta Proietti, Volker Schneck, Alain Servais, Brynjar Skúlason, Christoph Sperisen, Frank Wolter, Tefide Yüksel, Michele Bozzano, 2021, slovar, enciklopedija, leksikon, priročnik, atlas, zemljevid Povzetek: This report summarises the current state of knowledge in genetic aspects linked to the production and use of forest reproductive material (FRM). The first chapter describes the different categories of FRM, considers the strategic choice between artificial and natural regeneration in the face of climate change, and articulates the need for and purposes of FRM. Chapter 2 outlines the FRM production chain, in terms of: i) FRM approval, management, collection and certification (seed sources, stands, orchards, plus trees and clones others); ii) Testing standards and examples; iii) Effect of seed and seedling material not intended for use as FRM on forest genetic resources; iv) Breeding effects on basic material including conservation strategy; v) Harvesting, processing and storage of seeds; vi) Nursery practices; vii) Certification and Traceability; and viii) FRM Trading and Transport. Chapter 3 examines FRM with regard to: i) Forest regeneration strategies % especially considering climate change, and ii) Assisted migration and available decision support tools. Chapter 4 provides a detailed overview of forest establishment methods, and chapter 5 looks at keeping records of seed origin to improve forest management. The final chapter offers 38 recommendations arising from the review. This work is the result of an international collaboration rooted in EUFORGEN for more than two decades. It is built on the firm belief that the genetic element is decisive for the creation of a resilient forest capable of surviving threats and adapting to changes, thus enabling the evolution of ecosystems and the conservation of the productive landscape.
