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 …


Bryophyta Sensu Stricto Presence And Function In The Epiphytic Ecosystems Of The Tropical Montane Cloud Forests Of El Valle De Anton, Teaghan Duff 2023 SIT Study Abroad

Bryophyta Sensu Stricto Presence And Function In The Epiphytic Ecosystems Of The Tropical Montane Cloud Forests Of El Valle De Anton, Teaghan Duff

Independent Study Project (ISP) Collection

Bryophyta sensu stricto, colloquially known as moss, is often found growing epiphytically in cloud forest ecosystems. Under these conditions, moss may fulfill a secondary foundational species (FS) role, supporting increased habitat for other organisms while remaining dependent on the primary FS host tree. Exploring the dual relationship of moss as both a dependent and supportive organism allows for better understanding of its connective role within ecosystems. Research in the cloud forests of El Valle de Anton focused on relative abundance, environmental surroundings, morphology, and microclimate of mosses to offer baseline data on these connections. Mosses along four different trails within …


Soil Succession: Short And Long-Term Impacts Of Grazing On Soil Properties In A Tropical Montane Cloud Forest, June Curtis 2023 SIT Study Abroad

Soil Succession: Short And Long-Term Impacts Of Grazing On Soil Properties In A Tropical Montane Cloud Forest, June Curtis

Independent Study Project (ISP) Collection

Cattle ranching is the leading cause of deforestation in South America, causing long-lasting alterations to the continent's landscape and ecology. Tropical montane cloud forests (TMCFs) are a rare ecosystem particularly vulnerable to the effects of land conversion to pasture, a process which has implications ranging from biodiversity loss to soil degradation. Grazing is known to significantly alter soils' physical structure through processes of compaction and erosion as well as significant additions of organic matter. Silvopasture, or the integration of pasture and forest, has emerged as an alternative to traditional grazing practices with the hope of mitigating environmental and soil degradation. …


Variation Of Carbon Stock Of Boca Del Drago Mangrove Forests Based On Salinity And Seaward Proximity, Fiona Wyrtzen 2023 SIT Study Abroad

Variation Of Carbon Stock Of Boca Del Drago Mangrove Forests Based On Salinity And Seaward Proximity, Fiona Wyrtzen

Independent Study Project (ISP) Collection

Mangrove forests, at the intersection of land and sea, are considered one of the most important marine environments for their variety of ecosystem services and their ability to sequester large amounts of carbon in their biomass and adjacent soils. With a changing climate, many of the abiotic and biotic factors influencing mangroves will begin to shift, potentially impacting resilience, growth capacity, and distribution of mangroves worldwide. This study aimed to examine the influence of changing salinity on the carbon stock capacity for Rhizophora mangle and Laguncularia racemosa forests, and the distribution of biomass in each species relative to salinity in …


Mycorrhizal Fungi Mediate Aboveground – Belowground Interactions In Forest Ecosystems, Amelia A. Fitch 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 …

Marrow, Hilary L. Barker, Carolina Bernhardsson, Kennedy Rubert-Nason, Pär K. Ingvarsson, Richard L. Lindroth

Aspen Bibliography

Intraspecific genetic variations in foundation species such as aspen (Populus tremuloides Michx.) shapes their impact on forest structure and function. Identifying genes underlying ecologically important traits is key to understanding that impact. Previous studies, using single-locus genome-wide association (GWA) analyses to identify candidate genes, have identified fewer genes than anticipated for highly heritable quantitative traits. Mounting evidence suggests that polygenic control of quantitative traits is largely responsible for this "missing heritability" phenomenon. Our research characterized the genetic architecture of 30 ecologically important traits using a common garden of aspect through genomic and transcriptomic analyses. A multilocus association model revealed …

The measurement of forest structure has evolved steadily due to advances in technology, methodology, and theory. Such advances have greatly increased our capacity to describe key forest structural elements and resulted in a range of measurement approaches from traditional analog tools such as measurement tapes to highly derived and computationally intensive methods such as advanced remote sensing tools (e.g., lidar, radar). This assortment of measurement approaches results in structural metrics unique to each method, with the caveat that metrics may be biased or constrained by the measurement approach taken. While forest structural diversity (FSD) metrics foster novel research opportunities, understanding …


Fire Effects On Soil Organic Matter In The Creek Fire, Gracie E. Doolin 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 …

Declines in hunter numbers across the United States make hunter recruitment, retention, and reactivation (R3) a high priority for wildlife management. As wildlife management agencies and nongovernmental organizations seek to reach new audiences, college campuses present a unique opportunity to cultivate nontraditional path hunters. Despite recent proliferation of R3 initiatives, little research has evaluated effects of hunting programs on knowledge, attitudes, and behaviors of new hunters. We designed and implemented Getting Started Outdoors: Hunting 101 workshops specifically targeting college students without previous hunting experience, and we assessed workshop efficacy with a theoretically-grounded approach to workshop evaluation. Using quantitative and qualitative …

Object-Detection From Multi-View Remote Sensing Images: A Case Study Of Fruit And Flower Detection And Counting On A Central Florida Strawberry Farm, Caiwang Zheng, Tao Liu, Amr Abd-Elrahman, Vance M. Whitaker, Benjamin Wilkinson

Michigan Tech Publications

Object detection in remote sensing images is one of the most critical computer vision tasks for various earth observation applications. Previous studies applied object detection models to orthomosaic images generated from the SfM (Structure-from-Motion) analysis to perform object detection and counting. However, some small objects that are occluded from the vertical view but observable in raw images from the oblique views cannot be detected in the orthomosaic image, leading to an occlusion issue that cannot be resolved with the traditional orthophoto-based approach. Taking strawberry detection as a case study, the objective of this study is to detect small objects directly …
