Hoverflies (Diptera: Syrphidae) as biodiversity indicators for assessing urban forest habitats
Maarten De Groot, Primož Simončič, Andrej Verlič, Urša Vilhar, 2022, izvirni znanstveni članek

Povzetek: Urban and peri-urban forests are important habitats for maintaining biodiversity in cities. In this paper, we report a method for using hoverflies as biodiversity indicators in urban forest habitats. As a case study, forest habitats in three peri-urban and urban forests were assessed and compared to rural forests in Slovenia. Rožnik (Ljubljana) was chosen as the urban forest site, Mestni log (Ljubljana) and Brdo (Kranj) were chosen as the peri-urban sites, and eight sites were chosen in rural forests in different ecoregions in Slovenia. Forest hoverfly species richness and the species composition of different biological traits were compared between the peri-urban forests, urban forest and rural forest sites. In addition, species richness was assessed for changes in response to weather conditions between years. The number of species with the investigated traits in the urban and peri-urban forests was within the range of the number of species observed in the rural forests. The number of saproxylic species was higher in the urban forest but lower in the peri-urban forests compared to the rural forests. The proportions of species with different feeding modes and different development times were similar between the peri-urban, urban and rural forests. The proportions of species with development times of less than 2 months or more than 1 year and of predatory species were similar in the urban and peri-urban forests but higher in the rural forests. The species composition of the other biological traits differed between the peri-urban, urban and rural forests. Species richness and abundance displayed large differences in phenological patterns between 2012 and 2013; these differences are related to differences in the minimum temperature for these years. The results are discussed in relation to forest management in urban forests, the usefulness of hoverflies as a biodiversity indicator and possible extrapolation to other species groups.

Tree and stand growth differ among soil classes in semi-natural forests in central Europe
Andrej Bončina, Matija Klopčič, Vasilije Trifković, Andrej Ficko, Primož Simončič, 2023, izvirni znanstveni članek

Povzetek: We determined the size of differences in stand and tree growth in semi-natural forests with respect to 16 reference soil groups. The forest area of Slovenia (11.8 thousand km2) was used as the study area, and reference soil units were derived from the national soil map at a 1:25,000 scale consisting of 10,781 polygons with an average size of 117.95 ha. Stand growth was defined as periodic stand basal area increment, while the growth of Norway spruce, silver fir, Scots pine, European beech and sessile oak trees was estimated by the periodic diameter increment of 238,349 dominant trees on 67,061 permanent sampling plots. A linear fixed-effects model and linear mixed-effect models were used for studying stand and tree growth in different site, stand and tree conditions. The soil unit was the dummy variable with Dystric Cambisols set as the reference category. Soil contributed 4.3 % to the explained variability of basal area increment and 4–27 % to the explained variability of the diameter increment of the five tree species. Soil was a stronger driver of stand and tree growth than climate or topography. Stand and tree species production rate on soil units was in the interval of −28 % to +5 % and −47 % to +14 % of that on the reference soil unit, respectively. Stand growth was the highest on Eutric Gleysols and the lowest on Histosols, and tree species generally exhibited the highest and the lowest growth rates on different soil units. We suggest that soil should be considered in growth models and studied interrelatedly with climatic, site and stand variables.

Forest genetics research in the mediterranean basin : bibliometric analysis, knowledge gaps, and perspectives
Bruno 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.

Citizen science and monitoring forest pests : a beneficial alliance?
Maarten De Groot, Michael J.O. Pocock, Jochem Bonte, Pilar Fernandez-Conradi, Elena Valdés-Correcher, 2022, izvirni znanstveni članek

Povzetek: Purpose of the Review One of the major threats to tree health, and hence the resilience of forests and their provision of ecosystem services, is new and emerging pests. Therefore, forest health monitoring is of major importance to detect invasive, emerging and native pest outbreaks. This is usually done by foresters and forest health experts, but can also be complemented by citizen scientists. Here, we review the use of citizen science for detection and monitoring, as well as for hypothesis-driven research and evaluation of control measures as part of forest pest surveillance and research. We then examine its limitations and opportunities and make recommendations on the use of citizen science for forest pest monitoring. Recent Findings The main opportunities of citizen scientists for forest health are early warning, early detection of new pests, monitoring of impact of outbreaks and scientific research. Each domain has its own limitations, opportunities and recommendations to follow, as well as their own public engagement strategies. The development of new technologies provides many opportunities to involve citizen scientists in forest pest monitoring. To enhance the benefits of citizen scientists’ inclusion in monitoring, it is important that they are involved in the cocreation of activities. Summary Future monitoring and research may benefit from tailor-made citizen science projects to facilitate successful monitoring by citizen scientists and expand their practice to countries where the forest health sector is less developed. In this sense, citizen scientists can help understand and detect outbreaks of new pests and avoid problems in the future.

Forestry and the 40th anniversary of IALE
Janez Pirnat, 2022, predgovor, uvodnik, spremna beseda

Povzetek: In this paper we evaluated key forestry related topics in the journal Landscape Ecology in the period 1987-2021 using keyword analysis to highlight which forestry topics have been relevant for landscape ecologists from the inception of the IALE organisation until present. Our analysis has shown that forests have far too often been just a framework for research focusing on management interventions in the forest. The three key words with the highest frequencies were forest/wood fragmentation, forest management and forest(s). Until now, however, we have not made sufficient use of the opportunity to study the field of forest ecosystem functionning at the landscape level. Suggestions for future reserch are therefore given.

Common preferences of European small-scale forest owners towards contract-based management
Artti Juutinen, Elena Haeler, R. Jandl, Katharina Kuhlmey, Mikko Kurttila, Raisa Mäkipää, Tähti Pohjanmies, Lydia Rosenkranz, Mitja Skudnik, Matevž Triplat, Anne Tolvanen, Urša Vilhar, Kerstin Westin, Silvio Schueler, 2022, izvirni znanstveni članek

Povzetek: The societal demands on forest management are becoming increasingly diverse, which will be reflected in decisions made by forest owners. We examined the willingness of private forest owners in Austria, Finland, Germany, Slovenia, and Sweden to participate in a contract-based payment scheme in which they were asked to apply a specific management strategy to promote either timber production or environmental goals. The preferences for the contract-based management and associated consequences in terms of profitability, biodiversity, carbon stock, and climate change-induced damages were addressed within a choice experiment. A majority of respondents across all countries agreed to participate in a payment scheme to promote environmental goals, while schemes purely targeted to increase wood production were found less attractive. Forest owners liked improvements in profitability and environmental attributes and disliked deterioration of these attributes. Differences among countries were found in the level of expected contract payments, and commonalities were found with respect to preferences towards environmental goals, including biodiversity and carbon stocks. Hence, new policies to target European forest subsidy to promote the provision of environmental goals would likely be acceptable.
