Summary The invasive fungal pathogen Cronartium ribicola infects and kills whitebark pine ( Pinus albicaulis ) throughout western North America. Whitebark has been proposed for listing under the Endangered Species Act in USA, loss of this species is predicted to have severe impacts on ecosystem composition function high‐elevation forests. Numerous endophytes live inside tissues may influence severity C. infection, either directly by inhibition growth or indirectly induction chemical defensive pathways tree. Terpenes, a form defence trees, can also disease. In study, we characterized endophyte communities seedlings before after experimental inoculation with , monitored disease progression compared community susceptible vs. resistant common garden. We analysed terpene these same seedlings. Seed family identity maternal genetics influenced both terpenes communities. Terpene correlated severity, concentrations differed These results suggest that resistance observed natural populations caused combined effects genetics, within needle tissue, which initial interactions between microbes hosts take place.

Abstract Global conservation policy and action have largely neglected protecting monitoring genetic diversity—one of the three main pillars biodiversity. Genetic diversity (diversity within species) underlies species’ adaptation survival, ecosystem resilience, societal innovation. The low priority given to has been due knowledge gaps in key areas, including importance trends change; perceived high expense availability scattered nature data; complicated concepts information that are inaccessible policymakers. However, numerous recent advances knowledge, technology, databases, practice, capacity now set stage for better integration instruments efforts. We review these developments explore how they can support improved consideration global commitments enable countries monitor, report on, take maintain or restore diversity.

Summary One of Anthropocene's most daunting challenges for conservation biology is habitat extinction, caused by rapid global change. Tree diversity has persisted through previous episodes change, even extinctions. Given the pace current our management extant needs to facilitate and enhance natural ability trees adapt diversify. Numerous processes contribute this evolutionary flexibility, including introgression, a widespread yet under‐studied process. Reproductive networks, in which species remain distinct despite interspecific gene flow, are called syngameons, concept largely inspired from work focusing on Quercus . Delineating analyzing such groups, empirically theoretically, will provide insights into nonadditive effects evolution numerous partially interfertile exchanging genetic material episodically under changing environmental conditions. To conserve tree diversity, crossing experiments designed with an empirical theoretical understanding constituent syngameon should be set up assist diversification adaptation Anthropocene. Our increasingly detailed knowledge oak genome intraspecific phenotypic variation improve sustain unpredictable unprecedented future.

In recent years, forests have been exposed to an unprecedented rise in pests and pathogens. This, coupled with the added challenge of climate change, renders forest plantation stock vulnerable attack severely limits productivity. Genotypes resistant such biotic challenges are desired forestry reduce losses. Conventional breeding has a main avenue obtain genotypes. More recently, genetic engineering become viable approach develop resistance against pathogens trees. Tree genomic resources contributed advancements both these approaches. Genome-wide association studies selection tree populations accelerated tools whilst integration various levels omics information facilitates candidate genes for engineering. Furthermore, associations non-pathogenic endophytic subterranean microbes play critical role plant health may be engineered trees improve future. We look at describing defence mechanisms using approaches propose way forward developing superior genotypes enhanced stress.

Abstract Although it is an integral part of global change, most the research addressing effects climate change on forests have overlooked role environmental pollution. Similarly, studies investigating air pollutants generally neglected impacts change. We review current knowledge combined pollution and forest ecosystems identify several key priorities as a roadmap for future. Specifically, we recommend (1) establishment much denser array monitoring sites, particularly in South Hemisphere; (2) further integration ground satellite monitoring; (3) generation flux‐based standards critical levels taking into account sensitivity dominant tree species; (4) long‐term N, S, P cycles base cations deposition together at scale; (5) intensification experimental studies, different abiotic factors by assuring better representation taxonomic functional diversity across ~73,000 species Earth; (6) more focus phenomics genomics; (7) improved processes regulating dynamics radionuclides systems; (8) development models integrating data from programs.

Here we review evidence on potential viability such programme, from biological perspective. We conclude that aimed at resistance strains H . British Isles is biologically feasible. Summary To evaluate feasibility future produce trees an emerging pest pathogen, it helpful ask following questions: How much variation exists tree populations? what extent this heritable? many genetic loci are involved?
