Because green ash has an extensive range, its restoration could require both breeding for EAB resistance and possible adaptation to a variety of environmental gradients. We assessed the growth and climate sensitivity of green ash from five Plant Hardiness Zones (PHZs) growing in a range-wide provenance test in Vermont. Although there tended to be greater growth among trees from the warmest PHZ (7), differences were rarely statistically distinguishable. For trees from all PHZs, growth was positively correlated...AuthorsPaul Schaberg, Paula Murakami, Christopher F. Hansen, Gary J. HawleyKeywordsSourceCanadian Journal of Forest ResearchYear2024
- Aim: Forest pathogens, insect pests and parasitic plants are among the most important disturbance agents in forested ecosystems. Understanding where pests occur and where they might occur in the future will be important for understanding their impacts on host trees, and planning for future pest outbreaks. Location: North America. Taxon: Insect pests, pathogens and parasitic plants of forest trees. Methods: Here, we develop and implement a framework to predict the contemporary distributions of 26 pest species that accounts for climate, host abundance and, for non-native species, their...AuthorsAndrew Gougherty, Ashley Walters, Anantha M.

- To achieve reliable detection of environmental DNA from multiple species, a method which combines the specificity of single-taxon assays with the broad taxonomic coverage of metabarcoding is needed. High-throughput quantitative PCR (HT-qPCR) has emerged as one such method that holds particular promise for ecological applications. Here, we present the development and validation of a HT-qPCR biochip (i.e., biochip) protocol for a suite of western North American fishes with high cultural, economic, and ecological significance. Coupling this biochip with systematically distributed eDNA samples...AuthorsJoanna Elmore, Taylor Wilcox, Michael K. Young, Steve Kopp, Kellie Carim, Daniel Mason, Thomas W. Franklin, Michael K.

- A few iconic examples have proven the value of facilitated gene flow for counteracting inbreeding depression and staving off extinction, yet the practice is often not implemented for fear of causing outbreeding depression. Using genomic sequencing, climatic niche modeling, and demographic reconstruction, we sought to assess the risks and benefits of using translocations as a tool for recovery of endangered montane red fox (Vulpes vulpes) populations in the western United States. We demonstrated elevated inbreeding and homozygosity of deleterious alleles across all populations, but especiall...AuthorsCate Quinn, Sophie Preckler-Quisquater, Michael R. Buchalski, Benjamin N.

- Urban foresters today are faced with an unprecedented challenge in the context of climate change and social crises: achieving sustainability and resilience goals while supporting diversity, equity, inclusion, and justice. Experience suggests that partnerships are needed with community members who can provide local knowledge, legitimacy, and action beyond one plan, one agency, or one grant program, to influence the structure and function of the urban forest.AuthorsErika Svendsen, Lindsay K.

- Despite the recent increase in landscape conservation and the design processes agencies are undertaking, there remains an implementation gap due to an inability to evaluate general strategies and account for uncertainties faced by managers. We demonstrated how a decision support process (DSP), recently developed to inform landscape conservation design, can address uncertainties and complexities inherent in landscape conservation to facilitate long-term, large-scale conservation planning. We applied the DSP to landscape conservation efforts within conservation opportunity areas (COA) of...AuthorsThomas W. Bonnot, D. Todd Jones‐Farrand, Nate D. Muenks, Frank R.

- While extreme weather events are often localized, the potential effects on global forests can be far reaching due to the interconnected nature of forest product markets. To better understand these dynamics, this study leverages historical forest-based wind damage data in the United States and applies this information asshocks within a global forest sector outlook model. A large, localized wind event modeled as a shock to the US South creates a one-time increase of 18.7 million m3 from salvage harvest operations, equal to over 4% of national harvest. This crowds out traditional harvest...AuthorsCraig M. T. Johnston, Jesse Henderson, Jinggang Guo, Jeffrey P. Prestemon, Jennifer CostanzaKeywordsSourceEarth's FutureYear2024
- Plant diversity effects on community productivity often increase over time. Whether the strengthening of diversity effects is caused by temporal shifts in species-level overyielding (i.e., higher species-level productivity in diverse communities compared with monocultures) remains unclear. Here, using data from 65 grassland and forest biodiversity experiments, we show that the temporal strength of diversity effects at the community scale is underpinned by temporal changes in the species that yield. These temporal trends of species-level overyielding are shaped by plant ecological strategies...AuthorsLiting Zheng, Kathryn E. Barry, Nathaly R. Guerrero-Ramírez, Dylan Craven, Peter B.

- The framework of land degradation neutrality (LDN) and the concept of sustainable land management (SLM) are ways to instigate action required to address land degradation. Although land and water management approaches supporting SLM and the achievement of LDN exist, the transition to sustainable agricultural systems is hindered by various factors and the achievement of LDN is lagging behind. More information on such approaches is needed to sensitize decision-makers for fostering their implementation. This study responds to this need by examining the alignment of the following land and water...AuthorsLisa Hartmann, Yvonne Walz, Jonas Hansohm, Leticia Domingos Vellozo, Elizabeth Walinder, Olga Andreeva, Nicole Harari, John Hendrickson, Ivy Kinyua, John A.

- The Amazon forest contains globally important carbon stocks, but in recent years, atmospheric measurements suggest that it has been releasing more carbon than it has absorbed because of deforestation and forest degradation. Accurately attributing the sources of carbon loss to forest degradation and natural disturbances remains a challenge because of the difficulty of classifying disturbances and simultaneously estimating carbon changes. We used a unique, randomized, repeated, very high-resolution airborne laser scanning survey to provide a direct, detailed, and high-resolution partitioning...AuthorsOvidiu Csillik, Michael Keller, Marcos Longo, Antonio Ferraz, Ekena Rangel Pinagé, Eric Bastos Görgens, Jean P.
