Overview Fishes of the Adirondack Park face numerous challenges. Summer Suckers are the only endemic vertebrate yet have suffered major range reductions, so we are analyzing their genome, body shape, and spawning timing to verify their uniqueness and current range. Warming patterns are expected to shift their spawning earlier, potentially intersecting with their recent ancestor (White Suckers) to create hybridization and reduced reproductive success. Minnows are more diverse in the Adirondacks, and our analyses suggest that they show three major distributional patterns that reflect post-glacial colonization and temperature preferences. We are analyzing data from hundreds of lakes to discern the rules that structure...
Abstract (from Wiley): The brown-headed nuthatch (Sitta pusilla) was likely extirpated from Missouri in the early 1900s as a result of habitat loss through extensive logging. Conservation partners including the Missouri Department of Conservation, United States Forest Service, University of Missouri, and others, relocated 102 brown-headed nuthatches from Ouachita National Forest in Arkansas to Mark Twain National Forest in Missouri in 2020 and 2021 to establish a local population. We tracked 50 individuals for 24 ± 11 (median ± SD) days after release using radio telemetry and monitored movements in relation to sex and whether a bird was captured alone or as part of a group. We examined 25-day survival using a spatial...

Abstract (from ScienceDirect): Climate change poses threats to forests, creating a need for adaptation to novel and changing conditions. This need has led to the creation of adaptation frameworks including the resistance, resilience, transition (RRT) framework, which proposes management strategies along a gradient of change and adaptation. Although management within this framework is grounded in theory and past management experience, little is known about how these approaches may influence regeneration, a critical phase in forest development. To address this gap, we examined five-year outcomes of treatments implemented using the RRT framework as part of the Adaptive Silviculture for Climate Change network in northern...

The NE CASC Fellows Program is a training initiative to develop skills in engagement, communication, and collaboration to help inform climate change adaptation for natural and cultural resources management. Students and postdocs from the NE CASC consortium universities make up the fellows cohort and hail from diverse disciplines, including ecology, engineering, and earth and environmental sciences. Our common goal is to fulfill the mission of the NE CASC, which is to deliver science to help wildlife, ecosystems, and people adapt to a changing climate. Our challenge is to identify and build relationships with stakeholder partners to collaboratively design research that will meet their climate adaptation needs.
Deadwood moisture plays a major role in regulating deadwood decomposition rates and may also affect forest microclimate. Despite this, the temporal variability of deadwood moisture at 15-min time scales remains relatively unknown because techniques for using high-frequency sensors for tracking moisture at appropriate spatial and temporal intensities have been lacking. We installed a high-density sensor array in and around a downed log to gain a detailed assessment regarding the temporal variation of volumetric water content at multiple locations within one downed dead log, the source snag, and the surrounding soil. We also measured micrometeorological variables near the log in order to predict variability of the...

Abstract (from AcademicOUP): The introduced emerald ash borer (EAB) represents the costliest invasive forest insect in US history, causing significant mortality of ash species across much of eastern North America as well as in Colorado and Oregon. Few surviving overstory ash trees exist in areas first invaded by EAB, such as the Lake States region; however, forests with healthy, mature ash remain in recently invaded regions, such as the northeastern United States. Given the importance of ash to cultural lifeways of Indigenous peoples and the ecology and economies of working forest lands, there is growing interest in applying protection measures to maintain ash in forested settings. We further develop our call for...

One way that climate change is projected to affect invasive plant management is by shifting the ranges of invasive plants. In some regions, hundreds of new, potentially invasive species could establish in coming decades. These species are prime candidates for early detection and rapid response. However, with limited resources, it is unlikely that invasive plant managers will be able to monitor and treat this large number of novel species. Determining which species are likely to have the greatest impacts could inform further risk assessment and mitigate the greatest amount of potential damage. Here, we used the Environmental Impact Classification for Alien Taxa (EICAT) protocol to evaluate the potential impacts of...

The NE CASC consortium convenes three workshops that explore high-priority adaptation research topics emerging from our stakeholder networks and current DOI priorities. Workshops provide a platform to foster a collaborative community of scientists and managers, invite sharing and discussion of partner needs, and cross-disciplinary development and application of NE CASC-supported research, information, and data products. Year 1: Biological Thresholds in the Context of Climate Change (proceedings) Year 2: Future of Aquatic Flows (proceedings) Year 3: Climate-Adaptive Population Supplementation (proceedings)
Abstract (frrom Canadian Journal of Forest Research): Epigeous fungal fruiting has important impacts on fungal reproduction and ecosystem function. Forest disturbances, such as timber harvest, impact moisture, host availability, and substrate availability, which in turn may drive changes in fungal fruiting patterns and community structure. We surveyed mushrooms in 0.4 ha patch cuts (18 months post-harvest) and adjacent intact hardwood forest in northern New Hampshire, USA, to document the effects of timber harvest on summer fruiting richness, biomass, diversity, and community structure of ectomycorrhizal, parasitic, and saprobic mushroom taxa. Fungal fruiting richness, diversity, and community heterogeneity were...

We downloaded, cleaned, and combined records from Biodiversity Heritage Library’s (BHL) Seed and Nursery Catalog Collection with data from Restoring American Gardens: An encyclopedia of heirloom ornamental plants, 1640-1940 (RAG; Adams 2004) to create a single database of historical nursery sales in the U.S. Each record represents an individual taxon offered for sale at an individual time in a specific nursery’s catalog. We standardized records to the current World Flora Online (http://worldfloraonline.org) accepted taxonomy, and appended accepted USDA code, growth habit, and introduction status. We also appended whether taxa were reported as invasive in the Global Plant Invaders (GPI) dataset or the Global Invasive...
There is broad concern that the range shifts of global flora and fauna will not keep up with climate change, increasing the likelihood of population declines and extinctions. Many populations of nonnative species already have advantages over native species, including widespread human-aided dispersal and release from natural enemies. But do nonnative species also have an advantage with climate change? Here, we review observed and potential range shifts for native and nonnative species globally. We show that nonnative species are expanding their ranges 100 times faster than native species, reflecting both traits that enable rapid spread and ongoing human-mediated introduction. We further show that nonnative species...
