Underplanting before mortality from EAB is one approach being considered to replace black ash and maintain ecosystem functions. We report on third-year survival and growth responses of five underplanted tree species (red maple, silver maple, American elm, balsam poplar, and swamp white oak), to differences in seedling stock size, understory competition, and...AuthorsBrian J.

- The natural environment is integral to supporting healthy and resilient communities. Community forests (CFs) are forested parcels, typically in rural areas, where community members have access, share governance, and receive various benefits. While considerable research demonstrates that urban parks and forests are important for human health, similar assessments are less available for CFs specifically. Although CFs exist in multiple countries, their policy, ecological, ownership, and governance contexts differ significantly. This review focuses on CFs in the United States. The goals of this...AuthorsPooja S.

- Habitat suitability models (HSMs) play an important role in conservation planning by identifying areas for habitat management and guiding surveys for population discovery and monitoring. The wood turtle Glyptemys insculpta is a riverine turtle that uses both riparian and upland environments. Habitat loss and degradation have resulted in range‐wide declines of this species throughout the United States. Previous HSMs have been developed for wood turtles; however, no published HSM we are aware of exists for their range in the midwestern United States (including parts of Iowa, Michigan,...AuthorsSara M.

- Selection mosaic theory explains observations of polymorphism in host-pathogen interactions in terms of spatially variable natural selection but does not account for population dynamics. In contrast, classical host-pathogen theory easily explains observations of population cycles, but does not explain the persistence of pathogen polymorphism. Here, we synthesize these two frameworks to understand the effects of population cycles on pathogen polymorphism. We show that geographic variation in the frequency of two morphotypes of a baculovirus that infects the Douglas-fir tussock moth (Orgyia...AuthorsKatherine P. Dixon, William T. Koval, Carlos M.

- Tree longevity is thought to increase in growth-limiting, adverse environments, but a quantitative assessment of drivers of global variation in tree longevity is lacking. We assemble a global database of maximum longevity for 739 tree species and analyse associations between longevity and climate, soil, and species’ functional traits. Our results show two primary pathways towards long lifespans. The first is slow growth in resource-limited environments, consistent with the “adversity begets longevity” paradigm. The second pathway is through relief from abiotic constraints in productive...AuthorsRoel J. W. Brienen, Giuliano Maselli Locosselli, Stefan Krottenthaler, Emanuel Gloor, Robyn Wrigley, Steven L.

- Wildland-urban (WU) fires can devastate lives and communities, overwhelm emergency response efforts, and exhaust sheltering and recovery resources. Rapid fire spread into communities accounted for 78% of structure loss over 2001–2020, and rates of structure loss from such wildfires increased by 160% from 2010 to 2020 over the prior decade (1, 2). These fires carry enormous societal costs, including mortality, morbidity, loss of critical infrastructure and services, home destruction, and loss of insurance coverage (3, 4).AuthorsMatthew P.

- As the northern high-latitude permafrost zone experiences accelerated warming, permafrost has become vulnerable to widespread thaw. Simultaneously, wildfire activity across northern boreal forest and Arctic/subarctic tundra regions impacts permafrost stability through the combustion of insulating organic matter, vegetation, and post-fire changes in albedo. Efforts to synthesis the impacts of wildfire on permafrost are limited and are typically reliant on antecedent pre-fire conditions. To address this, we created the FireALT dataset by soliciting data contributions that included thaw depth...AuthorsAnna C. Talucci, Michael M. Loranty, Jean E. Holloway, Brendan M. Rogers, Heather D.

- Native fish populations and their habitats are declining in the southwestern United States. The upper Verde River (UVR) is one of a shrinking number of remaining perennial stream systems where multiple populations of native fish species still exist. This study utilized unoccupied aerial vehicle (UAV), terrestrial lidar, real-time kinematic (RTK) survey technology and environmental DNA (eDNA) sampling to assess current riparian and in-stream habitat conditions and compare them to an assessment conducted in 2009 to assess current suitability and long-term trends in populations and habitat...AuthorsJackson M.

- Environmental DNA (eDNA) sampling to monitor wildlife presence has mostly focused on water but increasingly includes soil, air, and creative biotic substrates like flowers and spiderwebs. Biotic substrates are unique in that they also provide insight into ecological interactions. Here we explore the ability of eDNA from songbird nests to reveal avian trophic ecology, such as nestling diet and nest predator identity, in addition to local insect biodiversity. Twenty‐two nests comprising five New World sparrow species and two nonsparrow passerines were collected in a montane sagebrush steppe...AuthorsJohn Kronenberger, Elise C.

- Local adaptation may facilitate range expansion during invasions, but the mechanisms underlying successful invasions remain unclear. Cheatgrass (Bromus tectorum), native to Eurasia and Africa, has invaded globally, with severe impacts in western North America. We aim to identify mechanisms and consequences of local adaptation in the North American cheatgrass invasion. We sequence 307 range-wide genotypes and conduct controlled experiments. We find that diverse lineages invaded North America, where long-distance gene flow is common. Nearly half of North American cheatgrass comprises a...AuthorsDiana Gamba, Megan L. Vahsen, Toby M.
