Logging and forest conversion are occurring at alarming rates in tropical forests. These disturbances alter soil microbial community structure and functions. While direct links between changes in soil properties, such as pH and microbial community structure are well established, the indirect effects of logging and forest conversion on soil microbial community structure and functions are poorly understood. We used a space-for-time substitution to investigate the changes in soil microbial diversity and functions across a forest recovery gradient in the tropical montane forests of northern Borneo. We used surface (top 5 cm) soil to assess soil physicochemical and microbial (next-generation DNA …

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, Part 1
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 …

Ungulate Herbivores As Drivers Of Aspen Recruitment And Understory Composition Throughout Arid Montane Landscapes, Elizabeth S. Reikowski, Tyler Refsland, J. Hall Cushman
Aspen Bibliography
Herbivory by wild and domestic ungulates can influence tree recruitment and understory forest communities throughout the world. Herbivore-driven declines in tree recruitment have been observed for quaking aspen (Populus tremuloides), a foundation species whose health and management is recognized as a critical priority throughout much of its range. Livestock fencing is commonly used to promote aspen regeneration, but its effectiveness is rarely assessed, especially across large spatial scales. Using a livestock-reduction experiment, we evaluated the effects of ungulate herbivory on aspen in the Great Basin and southern Cascades, an expansive and environmentally heterogeneous region where aspen faces the …

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 …

A Key Study On Pollen-Specific Sfb Genotype And Identification Of Novel Sfb Alleles From 48 Accessions In Japanese Apricot (Prunus Mume Sieb. Et Zucc.), Daouda Coulibaly, Guofeng Hu, Zhaojun Ni, Kenneth Omondi Ouma, Xiao Huang, Shahid Iqbal, Chengdong Ma, Ting Shi, Faisal Hayat, Benjamin Karikari, Zhihong Gao
Michigan Tech Publications, Part 1
Self-incompatibility (SI) is a common strategy to avoid inbreeding and, consequently, keep genetic diversity within a species. In its mechanism, pollen rejection happens in the style when the single multiallelic locus (SFB in prunus species) of the haploid pollen matches one of the S-alleles existing in the diploid pistil. The SFB gene for the pollen S gene has been identified in many Prunus species. However, Japanese apricot is a species with a typical gametophytic self-incompatibility (GSI), and its SFB alleles available are limited, although they are required for studying GSI. Therefore, we used an AS-PCR amplification method, sequencing, and the …

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.
Michigan Tech Publications, Part 1
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 …

Japanese apricot (Prunus mume Sieb. et Zucc.) is among the most valued fruits and flowering plants in eastern Asia. However, few comparative studies have been conducted with respect to its agro-morphological and pomological traits, chloroplast (cp) genome sequences and plastid diversity. Therefore, a comparative study was, conducted to investigate the divergence and geographic distribution of ten Japanese apricot accessions from three Chinese provinces (Zhejiang, Jiangsu and Sichuan). Phenotypic characteristics of the evaluated accessions, such as leaf length, tip leaf length, flower diameter, anther number, fruit weight, longitudinal height, transversal height, lateral height, fruit stone weight, stone longitudinal height, stone transversal …

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, Part 1
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 …

Lowering Water Table Reduces Carbon Sink Strength And Carbon Stocks In Northern Peatlands, Min Jung Kwon, Ashley Ballantyne, Philippe Ciais, Chunjing Qiu, Elodie Salmon, Nina Raoult, Bertrand Guenet, Mathias Göckede, Eugénie S. Euskirchen, Hannu Nykänen, Edward A. Schuur, Merritt R. Turetsky, Catherine M. Dieleman, Evan Kane, Donatella Zona
Michigan Tech Publications, Part 1
Peatlands at high latitudes have accumulated >400 Pg carbon (C) because saturated soil and cold temperatures suppress C decomposition. This substantial amount of C in Arctic and Boreal peatlands is potentially subject to increased decomposition if the water table (WT) decreases due to climate change, including permafrost thaw-related drying. Here, we optimize a version of the Organizing Carbon and Hydrology In Dynamic Ecosystems model (ORCHIDEE-PCH4) using site-specific observations to investigate changes in CO and CH fluxes as well as C stock responses to an experimentally manipulated decrease of WT at six northern peatlands. The unmanipulated control peatlands, with the WT …

Harvesting Intensity And Aridity Are More Important Than Climate Change In Affecting Future Carbon Stocks Of Douglas-Fir Forests, Alyssa J. Robinson, Camille E. Defrenne, W. Jean Roach, Caren C. Dymond, Brian J. Pickles, Suzanne W. Simard
Michigan Tech Publications, Part 1
Improved forest management may offer climate mitigation needed to hold warming to below 2°C. However, uncertainties persist about the effects of harvesting intensity on forest carbon sequestration, especially when considering interactions with regional climate and climate change. Here, we investigated the combined effects of harvesting intensity, climatic aridity, and climate change on carbon stocks in Douglas-fir [Pseudotsuga menziesii Mirb. (Franco)] stands. We used the Carbon Budget Model of the Canadian Forest Sector to simulate the harvest and regrowth of seven Douglas-fir stand types covering a 900 km-long climate gradient across British Columbia, Canada. In particular, we simulated stand growth under …

Assessing The Flood Tolerance, Physiological Mechanism, And Nutrient Mitigation Potential Of Short Rotation Woody Crops Planted On Seasonally Flooded Marginal Land Of The Lower Mississippi Alluvial Valley, Thu Ya Kyaw
Theses and Dissertations
In 2019, the Mississippi River watershed had a record-long flooding, which was comparable with the 1927 Great Mississippi River Flood. This study leveraged this flooded condition to assess the flood tolerance of eastern cottonwood (Populus deltoides) and black willow (Salix nigra) planted as short rotation woody crops (SRWCs) on seasonally flooded marginal land of the Lower Mississippi Alluvial Valley (LMAV) in 2018. The survival/mortality prediction models developed by using hydrologic and environmental variables suggested that only high flood depth affected the survival of black willow. However, eastern cottonwood was threatened by flood depth, flood duration, and …

Improvement Value Of Forest Resources By Use Of Cottonseed Protein Meal As A Bio-Based Wood Adhesive For Hardwood Plywood Products, Edward David Entsminger
Theses and Dissertations
Literature shows that production of cottonseed adhesives is feasible to develop an environmentally friendly and competitive bio-based wood adhesive. Defatted cottonseed and water-washed cottonseed meals were prepared from glandless cottonseed and were used in adhesive formulations to produce three-ply yellow poplar (Liriodendron tulipifera) plywood panels as the first objective. These two cottonseed meals were compared with the properties of plywood panels made with an adhesive formulated from a commercial soybean meal, as a control. Adhesive resins were prepared from each protein meal with sodium metabisulfite (Na2S2O5) and one of two polyamido-amine-epichlorohydrin (PAE) wet strength agents, and the plywood panels were …
