Understanding the factors that influence the distribution of species through time and across space is a fundamental goal of ecology and crucial information needed to effectively manage and recover populations. Anthropogenic fragmentation of habitat disrupts ecological processes …
In the wake of growing uncertainty around global future water supplies, and widening disparities in living conditions across nations, research into the factors propagating these issues is necessary to facilitate effective policy design. The following dissertation presents three …
Bonneville Cutthroat Trout (BCT) Oncorhynchus clarkii utah is one of fourteen subspecies of Cutthroat Trout Oncorhynchus clarkii and is a species of high ecological and social importance. Bonneville Cutthroat Trout is a species of conservation concern in the states of Idaho and …
Rangeland social-ecological systems in Northeastern (NE) Colorado are undergoing linked land-use, livelihood, and identity transitions. Land change is a spatially and temporally complex process in which land-use decisions cascade through interconnected social and ecological sphe…
Data assimilation in subsurface systems is challenging due to the large number of flow simulations often required, and by the need to preserve geological realism in the calibrated (posterior) models. In this work we present a deep-learning-based surrogate-modeling framework, ref…
This thesis describes population characteristics of Blue Catfish Ictalurus furcatus and Flathead Catfish Pylodictis olivaris within the Robert C. Byrd Pool of the Ohio and Kanawha rivers. Three chapters are included as follows: 1) An introduction and literature review, 2) An ass…
Quantification of various wood anatomical characteristics in annually resolved tree rings has been shown to reveal environmental information on seasonal or shorter timescales that is often not present in ring width alone. The genus Quercus is particularly important to dendroclim…
Negative interactions with nonnative species are a concern for many species including Yellowstone Cutthroat Trout (YCT) Oncorhynchus clarkii bouvieri . In many YCT fisheries, managers are tasked with balancing angler satisfaction and fish conservation. Trying to balance these ne…
Conservation conflict, whether human-wildlife or human-human, and specifically those that include the public as stakeholders, is seen as one of the most influential reasons reintroduction and/or conservation of species or landscapes is difficult to accomplish. This is due to the…
The environment, economy, and culture of the Caribbean (Miskitu) Coast of Nicaragua have been fundamentally shaped, since the colonial period, by boom-and-bust extractive natural resource industries. Coastal residents, many of whom are indigenous or Afro-descendant, have histori…
Deforestation is a critical global challenge in the 21st century. Policies that effectively tackle forest loss are essential given that the consequences of deforestation can be severe for both people and nature. There is hence an urgent need to generate knowledge about effective…
The central theme of this study is 'community conservation'. Specifically, it focuses on the social dynamics of external development intervention promoting the formation of joint state-community institutions for collective management of national park-based natural resources. As …
The Clean Development Mechanism (CDM) of the Kyoto Protocol offers developing countries the opportunity to participate in the effort to reduce global greenhouse gas levels while also benefitting from sustainable development opportunities. To date, the majority of CDM investments…
Cette étude s'intéresse au phénomène de la gestion des ressources naturelles en milieu rural nigérien. S'appuyant sur un projet de développement rural intégré œuvrant dans la région de Keita, ses investigations s'articulent autour des raisons qui auraient incité les femmes à s'i…
Microcredit has been considered one of the most significant innovations in the field of development in the last thirty years. It provides collateral free financial resources to the poor worldwide. It plays an important role in poverty eradication, socio-economic development, liv…
The Coral Triangle is an area with high marine biodiversity that encompasses four Asian (Indonesia, Malaysia, Philippines, and Timor Leste) and two Melanesian (Solomon Islands and Papua New Guinea) countries. The Coral Triangle Initiative on Coral Reefs, Fisheries and Food Secur…
Site productivity measures the primary productivity potential of forest ecosystems. It is characterized by an interaction of biotic and abiotic factors such as climate, soil, and topography. An accurate site productivity characterization allows for efficient land use allocation,…
The visual connection humans make with the 3-dimensional elements of their surrounding landscape - known as a viewscape (Vukomanovic et al. 2018) - is the primary way people connect with the environment (Kandel et al. 2000, Nujhuis et al. 2011). Thus, the ability to model where,…
