“…Numerous community genetics studies have demonstrated significant heritability of herbivore distributions among genotypes of various plant species (Genung et al ., 2012; Tovar‐Sánchez et al ., 2015; Gosney et al ., 2021). Our understanding of these arthropod community and plant genetic interactions has further expanded through research focused on the interplay between environment and plant chemical characteristics, especially in keystone forest trees species belonging to Eucalyptus (Barbour et al ., 2009a,b; Andrew et al ., 2010; Külheim et al ., 2011; Gosney et al ., 2017, 2021) and Populus (Eisenring et al ., 2021, 2022). Many of these same studies have often been limited in their ability to identify specific genes underlying individual arthropod distributions, let alone entire community interactions (Barker et al ., 2019; Wimp et al ., 2019).…”

“…The field of community genetics links ecology into this evolutionary framework to predict community structure and function as underlying genes shift within plant populations (Whitham et al ., 2006; Hughes et al ., 2008). Prior research of these relationships in both agricultural and natural ecological systems (Genung et al ., 2012; Tovar‐Sánchez et al ., 2015; Gosney et al ., 2021) has shown that plant genotype has a strong effect on herbivore distributions (Barbour et al ., 2016; Crutsinger, 2016). Additionally, in ecological systems, the impacts of plant genetics are expected to increase when a species is either dominant or foundational in the environment (Whitham et al ., 2003, 2006; Ellison et al ., 2005).…”

Summary Community genetics seeks to understand the mechanisms by which natural genetic variation in heritable host phenotypes can encompass assemblages of organisms such as bacteria, fungi, and many animals including arthropods. Prior studies that focused on plant genotypes have been unable to identify genes controlling community composition, a necessary step to predict ecosystem structure and function as underlying genes shift within plant populations. We surveyed arthropods within an association population of Populus trichocarpa in three common gardens to discover plant genes that contributed to arthropod community composition. We analyzed our surveys with traditional single‐trait genome‐wide association analysis (GWAS), multitrait GWAS, and functional networks built from a diverse set of plant phenotypes. Plant genotype was influential in structuring arthropod community composition among several garden sites. Candidate genes important for higher level organization of arthropod communities had broadly applicable functions, such as terpenoid biosynthesis and production of dsRNA binding proteins and protein kinases, which may be capable of targeting multiple arthropod species. We have demonstrated the ability to detect, in an uncontrolled environment, individual genes that are associated with the community assemblage of arthropods on a host plant, further enhancing our understanding of genetic mechanisms that impact ecosystem structure.

“…Quantitative genetic studies of these trials identified significant popula-tion differentiation in numerous traits, which was summarised by partitioning the gene pool into 13 geographic races [49]. While there are likely evolutionary constraints [52], population differences have been shown to: occur at multiple geographic scales, from hundreds of metres [53,54] to hundreds of kilometres [49,55], be adaptive (i.e., significant population × environment interactions for growth in common garden trials, [32]), and even to have extended community-level consequences [56,57]. Numerous traits exhibit clines with latitude and climate as well as signals of divergent selection (Q ST > F ST ) [47,49,58,59].…”

Understanding the capacity of forest tree species to adapt to climate change is of increasing importance for managing forest genetic resources. Through a genomics approach, we modelled spatial variation in climate adaptation within the Australian temperate forest tree Eucalyptus globulus, identified putative climate drivers of this genomic variation, and predicted locations of future climate refugia and populations at-risk of future maladaptation. Using 812,158 SNPs across 130 individuals from 30 populations (i.e., localities) spanning the species’ natural range, a gradientForest algorithm found 1177 SNPs associated with locality variation in home-site climate (climate-SNPs), putatively linking them to climate adaptation. Very few climate-SNPs were associated with population-level variation in drought susceptibility, signalling the multi-faceted nature and complexity of climate adaptation. Redundancy analysis (RDA) showed 24% of the climate-SNP variation could be explained by annual precipitation, isothermality, and maximum temperature of the warmest month. Spatial predictions of the RDA climate vectors associated with climate-SNPs allowed mapping of genomically informed climate selective surfaces across the species’ range under contemporary and projected future climates. These surfaces suggest over 50% of the current distribution of E. globulus will be outside the modelled adaptive range by 2070 and at risk of climate maladaptation. Such surfaces present a new integrated approach for natural resource managers to capture adaptive genetic variation and plan translocations in the face of climate change.

Summary We synthesise the findings from 10 years of ecological restoration in the Midlands of Tasmania, Australia, captured in the series of 14 papers in this special issue of Ecological Management and Restoration. The papers illustrate how expertise from disciplines as diverse as law, economics, social sciences, the arts, education, zoology, botany, genetics, climate modelling, agriculture, spatial sciences and fire ecology are necessary to address the complex social, ecological and financial questions that underpin restoration ecology. We highlight the complexity of the task, the multi‐disciplinary and collaborative approach needed, the importance of science to inform restoration practice and the problem of achieving functional connectivity. We also outline steps that need to be taken in the next 10 years. Together, the outcomes and recommendations from these studies provide a template for restoration in similar highly cleared and degraded agricultural landscapes affected by climate change in Australia and internationally.
