Impacts Of Forest Fire Carbon Emission And Mitigation Strategies, Zhihua Liu, Hongshi He, Wenru Xu, Yu Liang, Jiaojun Zhu, Geoff G. Wang, Wei Wei, Zifa Wang, Yongming Han
Bulletin of Chinese Academy of Sciences (Chinese Version)
Between 2000 and 2020, global wildfires contributed to approximately 7.32 billion metric tons of carbon dioxide (CO2) emissions, accounting for about 18.5% of CO2 emissions released from fossil fuels. Forest fires alone contributed to around 20% of these wildfire emissions, approximately 1.5 billion metric tons of CO2. Due to climate change and human activities, carbon emissions from forest fires are on the rise. For example, the 2023 Canadian fires have emitted 1.268 billion metric tons of CO2 up to August 29th. Despite the simultaneous increase in forest area and volume, the frequency and extent of forest fires have significantly decreased …

SIT Study Abroad
Intelligence Versus Inferno: How Artificial Intelligence Can Be Used To Monitor And Manage Wildfires In Europe, Maxwell Feldman
Independent Study Project (ISP) Collection
Escalating wildfire occurrences in Europe, particularly in the southern Mediterranean region, are presenting significant challenges to socioeconomic, environmental, and ecosystem services. The increasing frequency and severity of these wildfires are straining resources and emphasizing the need for a better understanding of the relationship between suppression capacity and fire behavior in wildfire management. The following research addresses the urgent need for more proactive, knowledge-based, and technologically driven fire management strategies, throughout all four stages of wildfire response – fuel and land management, fire preparedness, fire suppression, and post-fire management. Artificial Intelligence (AI) is becoming increasingly significant in climate change adaptation, especially …
Mycorrhizal Fungi Mediate Aboveground – Belowground Interactions In Forest Ecosystems,
2023
Dartmouth College
Mycorrhizal Fungi Mediate Aboveground – Belowground Interactions In Forest Ecosystems, Amelia A. Fitch
Dartmouth College Ph.D Dissertations
The activities of plants and soil microbes are the primary drivers of forest ecosystem processes such as carbon (C) and nitrogen (N) cycling, and mycorrhizal fungi serve as a bridge between these two groups of organisms. The combined efforts of trees and associated mycorrhizal fungi to seek soil nutrients links C and N cycling through effects on saprotrophic communities and decomposition activity. In these studies, I investigated the effects of arbuscular (AM) and ectomycorrhizal (EcM) associations on microbial communities and ecosystem processes related to SOM decomposition and N cycling, and in turn how differences in soils beneath AM and EcM …

Alpha Diversity And Species Status Of Uneven Forests In Eco-Zones Of Taraba State, Nigeria, Dau Henry Japheth, Joseph A. Ugbe, Jerry I. Alfa
Journal of Bioresource Management
Alpha diversity indices quantify the uncertainty in predicting the species identity of an individual. Quantitative indices on species composition and distribution are vital to understanding the trend and species status of an ecosystem for conservation management. However, among the forest ecosystems in Taraba state, Bakin Dutse and Wasaji uneven forests are one of the least studied areas, especially in terms of tree species status. This research work aims at assessing alpha diversity and species status of selected uneven forests in Taraba state, Nigeria; to provide baseline knowledge for conservation management. In total, 102 tree species from 74 genera and 41 …

Fire Effects On Soil Organic Matter In The Creek Fire,
2023
California Polytechnic State University, San Luis Obispo
Fire Effects On Soil Organic Matter In The Creek Fire, Gracie E. Doolin
Master of Science in Environmental Sciences and Management Projects
Wildfires have increased in frequency and severity over the past few decades due to the increased concertation of CO2 emissions from anthropogenic influence. Soil carbon (C) sequestration has been identified as a climate change mitigation strategy; however, the influx of large-scale wildfires has accelerated landscape processes such as erosion, reducing soil aggradation, and soil C and nitrogen (N) protection. This trend is highlighted by the Creek Fire that occurred in September 2020 and burned 379,895 acres in the Sierra National Forest. This research is designed to close the knowledge gap regarding the impact of burn severity on soil organic matter …
Remote Sensing Characterization Of Ecosystem Structure And Functional Types To Inform On Biodiversity Conservation In The Lowland Chocó Rainforest,
2023
CUNY Graduate Center
Remote Sensing Characterization Of Ecosystem Structure And Functional Types To Inform On Biodiversity Conservation In The Lowland Chocó Rainforest, Derek Tesser
Dissertations, Theses, and Capstone Projects
This dissertation focuses on the utilization of remote sensing techniques to characterize ecosystem structure and functional types to inform on biodiversity conservation. This work is motivated by a guiding hypothesis that increased degradation of tropical forest biodiversity due to human activity results in in measurable changes in ecosystem processes that can be detected using remote sensing technologies. Throughout this dissertation, testing of aspects of this hypothesis involve comparing areas with varying degrees of human-induced degradation in a biodiverse tropical ecoregion, the lowland Chocó rainforest of Ecuador. Remote sensing data is used to evaluate changes in vegetation structure, thermal regimes, and …

Modeling The Effect Of Neighborhood Competition On Tree Diameter Growth In The Pacific Northwest Coast Range, Htet Lin Naing
Theses and Dissertations
Trees compete for various resources such as sunlight, water, and nutrients, which can be expressed as numerical terms, called competition indices (CI). Competition between individual trees is correlated with their growth and mortality. Therefore, CIs are used as independent variables to develop, improve and modify growth and yield models. This study was conducted to test the effect of neighborhood competition on tree diameter growth among Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), western hemlock (Tsuga heterophylla (Raf.) Sarg) and red alder (Alnus rubra Bong.), in the Pacific Northwest Coast Range, USA. After testing seven distance-independent CIs and three distance-dependent …

Gene Expression Effects On Productivity And Stress Tolerance In Polyclonal Plantings Of Populus Deltoides, Macy Gosselaar
Theses and Dissertations
Polyclonal plantings of Populus deltoides are expected to display increased site resource use, productivity, and tolerance to stress through plasticity changes leading to niche differentiation (i.e changes to crown/canopy structures). In the present study, P. deltoides Clones S7C8, 110412, and polyclonal plots were tested for differentially expressed genes and enriched biological pathways between planting schemes. Transcriptomic analysis of leaves revealed upregulation of an active growth gene and gene family members that play important roles in plant stress and stress tolerance in polyclonal plantings. A gene associated with oxidative stress was upregulated in polyclonal plantings across all treatments. Secondary metabolic pathways …

Leaf Area Index And Aboveground Biomass Estimation Of Populus And Its Hybrids Using Terrestrial Lidar, Surya Adhikari
Theses and Dissertations
Short rotation woody crops (SRWC) eastern cottonwood (Populus deltoides) and hybrid poplar plantations were established in 2021 in Pontotoc and Oktibbeha counties of Mississippi to study the biomass potential of SRWC for biofuel production. We used a novel backpack LiDAR system to measure forest metrics and harvested sample trees to build aboveground biomass (AGB) and leaf area index (LAI) equations. The results showed that LiDAR-derived variables accurately estimated aboveground biomass (R2 =0.81 and 29.22 % RMSE). However, the LAI estimation results showed that the LiDAR metrics moderately explained field measurements of LAI (R2 =0.31 and 18.05% …
Maximum Size-Density Relationships In Mixed-Species And Monospecific Stands Of The Southeastern United States,

Mississippi State University
Maximum Size-Density Relationships In Mixed-Species And Monospecific Stands Of The Southeastern United States, Maxwell Robert Schrimpf
Theses and Dissertations
Maximum size-density relationships (MSDR) are used to quantify differences across sites in the number of trees of a given size and species that can be supported per hectare. These relationships are important to managers who are trying to maximize basal area and wood volume. In my study, I examined MSDR across Alabama, Georgia, Louisiana, and Mississippi using US Forest Service, Forest Inventory and Analysis (FIA) data. I determined the impact of species-specific, specific gravity, functional traits, and environmental factors on MSDR using a quantile regression approach. Overall, I found that climatic factors had the greatest influence on MSDR, and that …
Effects Of Fire Seasonality On Bachman’S Sparrows In The Longleaf Pine Forests Of Southern Mississippi,

Effects Of Fire Seasonality On Bachman’S Sparrows In The Longleaf Pine Forests Of Southern Mississippi, Michael D. Warren
Theses and Dissertations
The Bachman’s sparrow (Peucaea aestivalis) is a ground-dwelling, pine-obligate species experiencing range-wide population declines due to land development and fire exclusion. We explored the effects of fire seasonality on wintering Bachman’s sparrow abundance in Southern Mississippi from 2021-2022. We used generalized linear mixed models to investigate differences in sparrow abundance and vegetation characteristics following dormant and growing season fire. We explored the effects of growing season fire on breeding territory vegetation characteristics. Our results indicate that burn type (dormant vs. growing season), native grass groundcover, and shrubs over 1m were the most significant predictors for wintering Bachman’s sparrow …
A Silvicultural Approach To Increase Drought Resistance And Resilience In Longleaf Pine,

A Silvicultural Approach To Increase Drought Resistance And Resilience In Longleaf Pine, Kyle R. Dues
Theses and Dissertations
Droughts are a common disturbance experienced by forest systems across the southeastern United States and are expected to increase in frequency in the near future. Few empirical studies have evaluated the response of individual tree resistance and resilience following silvicultural treatment in longleaf pine (Pinus palustris Mill.). This study evaluates the differences in drought responses between two forests during three different periods. The first period evaluated pretreatment (2000) conditions, while the second (2006), and third (2011) compared conditions after the implementation of five silvicultural treatments. The main findings are that, as additional basal area is removed, both individual tree …
