ABSTRACT Climate change poses an unprecedented threat to forest ecosystems, necessitating innovative adaptation strategies. Traditional assisted migration approaches, while promising, face challenges related environmental constraints, forestry practices, phytosanitary risks, economic barriers, and legal constraints. This has sparked debate within the scientific community, with some advocating for broader implementation of despite these limitations, others emphasize importance local...
Our recent publication on pollen‐based assisted migration has prompted concerns about its feasibility and effectiveness. In this response article, we address those by presenting large‐scale examples of supplemental controlled pollination from Sweden the United States, demonstrating practical application. We also highlight existence an extensive global network seed orchards expand benefits migration, further reinforcing potential addressing raised concerns.
Abstract We investigated the genetic structure of three phenotypically distinct ecotypic groups Norway spruce ( Picea abies ) belonging to elevational classes; namely, low- acuminata ), medium- europaea , and high-elevation obovata form, each represented by 150 trees. After rigorous filtering, we used 1916 Genotyping-by-Sequencing generated SNPs for analysis. Outputs from multivariate analysis methods (Bayesian clustering algorithm implemented in STRUCTURE, Principal Component Analysis,...
Norway spruce has a wide natural distribution range, harboring substantial physiological and genetic variation. There are three altitudinal ecotypes described in this species. Each ecotype been shaped by selection retains morphological characteristics. Foliar spectral reflectance is readily used evaluating the status of crops forest ecosystems. However, underlying genetics foliar pigment content trees rarely investigated. We assessed clonal bank comprising two dates covering different...
Current knowledge of the genetic mechanisms underlying inheritance photosynthetic activity in forest trees is generally limited, yet it essential both for various practical forestry purposes and better understanding broader evolutionary mechanisms. In this study, we investigated variation selected chlorophyll a fluorescence (ChlF) parameters structured populations Scots pine (Pinus sylvestris L.) grown on two sites under non-stress conditions. These were derived from OJIP part ChlF kinetics...
Norway spruce is a widespread and economically highly important tree species in Central Europe which occurs there different morphotypic forms (also known as ecotypes). Previously established common garden experiments indicated that the morphological differentiation most likely genetically determined. The genetic structure of variants might be an indicator (marker) specific sustainability forest ecosystems. In this study, we investigated 436 individuals from autochthonous populations...
Seed orchards main function is delivering breeding programs' gains in the form of genetically improved seedlings. They are unique experimental populations, perfectly suited for studying various pollination environments (natural or otherwise), affecting their mating system parameters. Here, under different environment and intrusive (pollen augmentation and/or bloom-delay)), a second generation, wind-pollinated, coastal Douglas-fir (Pseudotsuga menziesii var. (Mirb.) Franco) seed orchard was...
Norway spruce has a broad natural distribution range, which results in substantial variety of its physiological and genetic variation. There are three distinct altitudinal ecotypes described this tree species. The optimum each ecotype may be shifted due to ongoing climate change, especially traits associated with water demand that might crucial for adaptation. Dehydrins proteins help mitigate the adverse effects dehydration. Dehydrin gene expression patterns appeared suitable marker plant...
Anthropogenic disturbances and climate change affect abiotic biotic environmental drivers in forest ecosystems. Global warming impacts the soil moisture content, thus influencing diversity, abundance functioning of microfauna. However, limited studies have been conducted to evaluate impact long-term variation precipitation on A better understanding microfauna under various regimes can aid formulating prediction models for assessing future impacts. The present study uses a multi-omics...
Norway Spruce (Picea abies (L.) H. Karst.), a timber species of significant economic and ecological importance in the Northern Hemisphere, faces increasing threats imposed by drought bark beetle infestation intensified ongoing climate change. Despite extensive mortality within stands, small proportion mature trees remarkably survive during severe outbreaks. Hypothesizing that resilience is genetically determined thus under natural selection, we anticipated there genetic variation genome...
The rhizosphere is the hotspot for microbial enzyme activities and contributes to carbon cycling. Precipitation an important component of global climate change that can profoundly alter belowground communities. However, impact precipitation on conifer rhizospheric populations has not been investigated in detail. In present study, using high-throughput amplicon sequencing, we soil communities two Norway Spruce clonal seed orchards, Lipová Lhota (L-site) Prenet (P-site). P-site received nearly...
Norway spruce, economically and ecologically one of the most important European forest tree species, rapidly declines due to massive bark beetle outbreaks across many countries. As a prerequisite ecosystem stability facing climate changes uncertain predictions, reforestation management promoting locally adapted resources broad genetic diversity should be prioritized, especially in nature conservation areas. In our case study carried out national park, Krkonoše Mountains (the Giant Mountains,...
