Special Issue Information

Dear Colleagues,

Global change including climate change, such as warming and drought, environmental pollution, biogeochemical cycles, and their synergism and interaction, directly or indirectly impact the forest ecosystems. The result is forest degeneration or changes in the structure and function of forest vegetation. Therefore, there is not only a change in the environmental conditions but also in the plant species and communities. Response and feedback processes such as BVOC emission at different levels ranging from the individual tree to a community of forests are unlikely to keep up with the speed of climatic changes in future. Particularly, extreme climatic scenarios, such as warming and drought, and abiotic stresses including air and soil pollution, can jointly cause extensive damage. For these reasons, it is essential to gain sufficient knowledge about the changes in response and feedback mechanisms as a result of global change. We encourage studies from all fields, including experimental studies, field surveys, and monitoring approaches, to contribute to this Special Issue in order to broaden the knowledge on response mechanisms and adaptation strategies of tree species and forest vegetation in natural and urban environments for the sustainable management and development of forest ecosystems under the background of global change.

The aim of this study was to identify changes in the concentrations of elements in fir assimilation organs over the past 30 years in order to assess fir reactions as a bioindicator of changes in the functioning of Central European fir forest ecosystems under conditions of reduced anthropogenic emissions. In particular, we selected the example of the Świętokrzyskie Mountains (Świętokrzyski National Park located in the northern range of Abies alba Mill.). The research was carried out in the “Łysica-Święty Krzyż” area under strict protection, including multi-species and uneven-aged tree stands with a complex structure, dominance of beech and fir, and numerous admixtures of other tree species. A decrease in the concentrations of pollutants in fir needles indicates a significant reduction in pressure on the environment and an improvement in the conditions of ecosystems in 2018 compared with those in 1986. In the period of more than 30 years between the sets of research, the concentrations of lead in fir needles decreased threefold and those of sulfur decreased twofold. A significant increase in the concentrations of cadmium, copper, manganese, and zinc in the three-year-old needles showed that they are a good indicator of environmental pollution with trace elements and may be used in biomonitoring.

Drought resistance in plants is controlled by multiple genes. To identify the genes that mediate drought stress responses and to assess the associated metabolic pathways in the desert shrub Nitraria tangutorum, we conducted a transcriptome analysis of plants under control (maximum field capacity) and drought (20% of the maximum field capacity) conditions. We analyzed differentially expressed genes (DEGs) of N. tangutorum and their enrichment in the KEGG metabolic pathways database, and explored the molecular biological mechanisms underlying the answer to its drought tolerance. Between the control and drought groups, 119 classified metabolic pathways annotated 3047 DEGs in the KEGG database. For drought tolerance, nitrate reductase (NR) gene expression was downregulated, indicating that NR activity was decreased to improve drought tolerance. In ammonium assimilation, drought stress inhibited glutamine formation. Protochlorophyllide reductase (1.3.1.33) expression was upregulated to promote chlorophyll a synthesis, whereas divinyl reductase (1.3.1.75) expression was downregulated to inhibit chlorophyll-ester a synthesis. The expression of the chlorophyll synthase (2.5.1.62) gene was downregulated, which affected the synthesis of chlorophyll a and b. Overall, drought stress appeared to improve the ability to convert chlorophyll b into chlorophyll a. Our data serve as a theoretical foundation for further elucidating the growth regulatory mechanism of desert xerophytes, thereby facilitating the development and cultivation of new, drought-resistant genotypes for the purpose of improving desert ecosystems.

Forest degradation and mortality have been widely reported in the context of increasingly significant global climate change. As the country with the largest total tree plantation area globally, China has a great responsibility in forestry management to cope with climate change effectively. Mongolian Scots pine (Pinus sylvestris var. mongolica) was widely introduced from its natural sites in China into several other sandy land areas for establishing shelterbelt in the Three-North Shelter Forest Program, scoring outstanding achievements in terms of wind-breaking and sand-fixing. Mongolian Scots pine plantations in China cover a total area of ~800,000 hectares, with the eldest trees having >60 years. However, plantation trees have been affected by premature senescence in their middle-age stages (i.e., dieback, growth decline, and death) since the 1990s. This phenomenon has raised concerns about the suitability of Mongolian Scots pine to sandy habitats and the rationality for further afforestation, especially under the global climate change scenario. Fortunately, dieback has occurred only sporadically at specific sites and in certain years and has not spread to other regions in northern China; nevertheless, global climate change has become increasingly significant in that region. These observations reflect the strong drought resistance and adaptability of Mongolian Scots pines. In this review, we summarized the most recent findings on the ecohydrological attributes of Mongolian Scots pine during its adaptation to both fragile habitats and climate change. Five main species-specific strategies (i.e., opportunistic water absorb strategy, hydraulic failure risk avoidance strategy, water conservation strategy, functional traits adjustment strategy, rapid regeneration strategy) were summarized, providing deep insights into the tree–water relationship. Overall, the findings of this study can be applied to improve plantation management and better cope with climate-change-related drought stress. Full article
