Pando's Pulse: Vital Signs Signal Need For Course Correction At World-Renowned Aspen Forest, Paul C. Rogers 2022 Utah State University

Pando's Pulse: Vital Signs Signal Need For Course Correction At World-Renowned Aspen Forest, Paul C. Rogers

Aspen Bibliography

Upland aspen (Populus spp.) forests contribute significantly to biodiversity in their circumboreal role as keystone species. As aspen ecosystems flourish or diminish, myriad dependent species follow suit. The 43-hectare Pando aspen (Populus tremuloides Michx.) clone in Utah, USA, is thought to be the largest living organism on earth, but is faltering due to chronic herbivory. Long-term resilience in aspen communities, including Pando, rests on successful recruitment of vegetative suckers that are nutritiously desirable to browsing ungulates. Here, I evaluate aspen reproduction alongside numerous vital indicators of Pando's status in the first trend assessment of this embattled iconic forest. …


European Mushroom Assemblages Are Phylogenetically Structured By Temperature, Claus Bässler, Jacob Heilmann-Clausen, Carrie Andrew, Lynne Boddy, Ulf Büntgen, Jeffrey Diez, et. al. 2022 Goethe-Universität Frankfurt am Main

European Mushroom Assemblages Are Phylogenetically Structured By Temperature, Claus Bässler, Jacob Heilmann-Clausen, Carrie Andrew, Lynne Boddy, Ulf Büntgen, Jeffrey Diez, Et. Al.

Michigan Tech Publications

Recent global warming affects species compositions at an unprecedented rate. To predict climate-induced changes in species assemblages, a better understanding of the link between species occurrence and climate is needed. Macrofungal fruit body assemblages are correlated with the thermal environment at the European scale. However, it is still unknown whether macrofungal communities are also phylogenetically structured by thermal environments. Thermal environments are characterized by annual temperature means but also by intra-annual temperature variability (hereafter termed temperature seasonality), which are both considered in this study. Here, we used distribution data of 2882 species based on fruit body records across Europe to …

Post-Fire Erosion Following The Czu Lightning Complex Fire: Quantifying Hillslope Erosion And Providing Guidance Towards Improving Post-Fire Response, Matthew C. Crockett, Matthew Crockett 2022 California Polytechnic State University, San Luis Obispo

Post-Fire Erosion Following The Czu Lightning Complex Fire: Quantifying Hillslope Erosion And Providing Guidance Towards Improving Post-Fire Response, Matthew C. Crockett, Matthew Crockett

Master of Science in Environmental Sciences and Management Projects

The size and severity of wildfires have increased in California during recent decades. This trend is highlighted through the CZU Lightning Complex fire of August 2020 which burned over 86,000 acres in the Santa Cruz mountains of California. The fire greatly impacted the Little Creek watershed, a roughly 1,300 acre watershed that exists largely within Cal Poly San Luis Obispo’s Swanton Pacific Ranch (SPR). The current trends of California’s increased wildfire regime are expected to continue, raising concerns regarding the direct and secondary effects on forest watersheds and the effectiveness of current post-fire erosion control management. Accelerated rates of erosion …


Nutrient Dynamics And Ecosystem Development Of Urban Forests, Gisselle A. Mejía 2022 The Graduate Center, City University of New York

Nutrient Dynamics And Ecosystem Development Of Urban Forests, Gisselle A. Mejía

Dissertations, Theses, and Capstone Projects

Urban growth and expansion are a major component of global environmental change, with impacts on climate, air and water quality, biodiversity, and human well-being. Forests embedded in urban landscapes are critical in mitigating these impacts at local, regional, and continental scales. However, assessing urban forests is difficult because cities are heterogenous in physical, chemical, biological, and social dimensions. This heterogeneity has constrained how urban forests are defined, and therefore, how they are studied. The objective of this dissertation is to determine how these biophysical and social factors drive ecological processes in urban forests and will address three outstanding challenges in …


Current Status And Trends In Forest Genomics, Dulal Borthakur, Victor Busov, Xuan Hieu Cao, Qingzhang Du, Oliver Gailing, Fikret Isik, Hairong Wei, et. al. 2022 University of Hawaii at Manoa

Current Status And Trends In Forest Genomics, Dulal Borthakur, Victor Busov, Xuan Hieu Cao, Qingzhang Du, Oliver Gailing, Fikret Isik, Hairong Wei, Et. Al.

Michigan Tech Publications

Forests are not only the most predominant of the Earth's terrestrial ecosystems, but are also the core supply for essential products for human use. However, global climate change and ongoing population explosion severely threatens the health of the forest ecosystem and aggravtes the deforestation and forest degradation. Forest genomics has great potential of increasing forest productivity and adaptation to the changing climate. In the last two decades, the field of forest genomics has advanced quickly owing to the advent of multiple high-throughput sequencing technologies, single cell RNA-seq, clustered regularly interspaced short palindromic repeats (CRISPR)-mediated genome editing, and spatial transcriptomes, as …

Contact Dewatering Of Cellulose Nanofibers For Biopolymer Composite Applications, Alexander Collins 2022 University of Maine

Contact Dewatering Of Cellulose Nanofibers For Biopolymer Composite Applications, Alexander Collins

Electronic Theses and Dissertations

Cellulose Nanofibrils (CNFs) are promising materials for reinforcement of polymer matrices attributable to their impressive physical and mechanical properties, as well as their biodegradability. However, the utilization of these materials in composites is made challenging by the water content of CNF slurries, the tendency of CNFs to agglomerate as they dry, and incompatibility between hydrophilic CNFs and hydrophobic polymer matrices. The most commercially viable drying methods to produce small-scale dry CNFs, such as spray drying, are very energy intensive, can only dry the materials down to micron-scale agglomerates, and do not preserve fibrillar aspect ratios. “Contact dewatering,” or the removal …


Northern White-Cedar Stand Structure, Composition, And Ecophysiology: Implications For Management And Climate Change Resilience, Katlyn Schulz 2022 University of Maine

Northern White-Cedar Stand Structure, Composition, And Ecophysiology: Implications For Management And Climate Change Resilience, Katlyn Schulz

Electronic Theses and Dissertations

Low rates of regeneration and recruitment for northern white-cedar (Thuja occidentalis) have been observed in lowland forests in some parts of its range, especially in comparison to its main tree competitor, balsam fir (Abies balsamea). In addition, climate projections suggest that suitable habitat conditions for the two species will decline in the northeastern United States and adjacent Canada due to widespread warming and increased variation in the timing and amount of precipitation. As such, future climate conditions may alter the competitive dynamics of these two species, which poses a major challenge for mitigating the negative effects of climate change through …


Joint Impacts Of Future Climate Conditions And Invasive Species On Black Ash Forested Wetlands, Joseph Shannon, Randall Kolka, Matthew Van Grinsven, Fengjing Liu 2022 Michigan Technological University

Joint Impacts Of Future Climate Conditions And Invasive Species On Black Ash Forested Wetlands, Joseph Shannon, Randall Kolka, Matthew Van Grinsven, Fengjing Liu

Michigan Tech Publications

Wetlands around the globe are being impacted by changing temperature and precipitation patterns. Simultaneously black ash forested wetlands are expected to lose much of their overstory canopy due to the invasive Emerald Ash Borer (EAB). Field experiments and modeling efforts have provided information on species tolerance of post-EAB conditions and future climate adapted species. No studies have yet examined the interaction of the loss of ash and future climate scenarios on wetland hydrologic conditions. We developed daily wetland hydrology models for three vegetation conditions: black ash forest, alternate non-ash forest, and non-forested. Model simulations were evaluated under current climate conditions …
