Macroscopic insights from mechanistic ecological network models in a data void
… of components at lower levels of organization. Network modeling and analysis, being a powerful tool that can capture the interconnections that embody complex behaviour, has therefore been at the forefront of complexity science. In ecology, the network paradigm is relatively young and there …

Resilience Engineering via Bifurcation and Ecological Network Analysis: Demonstrated in an Electric Power Case Study
… of new technologies and actors into the network, enables reliable operation but introduces vulnerabilities to unexpected and varied disruptions and cascading failures, making resilience a critical concern. Traditional risk management and resilience assessment methods often struggle with …

Leveraging Information Theory and Ecological Network Analysis to Monitor Communication Networks in a Student Aerospace Team
… and graph theory to analyze communication networks within a university’s multi-year, student-led cubesat design project (Project COMET). By utilizing Shannon Entropy as a measure of information flow, encoding communication patterns, and analyzing Ecological Network Analysis parameters, this …

On the origins of buildings: A social-ecological network approach to contemporary bioregional architectures of American earth, Norwegian timber & Balinese bamboo
… this thesis examines the relevance of a social-ecological network (SEN) approach. Results indicate SENs are increasingly useful tools for representing and analysing compound relationships between ecological and social systems for the management of ecosystem services. Still, applications to …

Modeling and Analysis of Interaction Networks in Ecological Systems
Understanding how networks form and evolve is an important question in many fields such as ecology, epidemiology, economics, and sociology. Studying the mechanisms of network formation can yield insight into which factors are involved in edge formation and network growth. This thesis explores …

Microbial adaptation, differentiation, and community structure
… we investigate the genetic basis of bacterial ecological differentiation by analyzing the genomes of two closely related, yet ecologically distinct populations of Vibrio splendidus. We nd that most loci recombine freely across habitats, and that ecological differentiation is likely driven by a …

The structure and stability of ecological networks
… interact with other species to form complex networks of connections. Such networks are a powerful way to represent ecological communities because they describe (i) the roles of individual species and (ii) the structure of the community as a whole in a single framework amenable to mathematical …

An Integrated Evaluation of the Conservation Reserve Enhancement Program in South Dakota
… America typically share the goal of improving ecological conditions for wildlife; however, it is unclear in many cases if goals are met. The South Dakota Conservation Reserve Enhancement Program (CREP) was initiated to alleviate agriculturally-related environmental degradation by converting …

Valuing the ecosystem services provided by UK bats under climate change
… of agricultural pests populations, yet the ecological mechanisms linking bat biodiversity to potential pest suppression, and the economic value of this service, remain poorly understood. This thesis investigates how climate change may affect bat communities, their trophic interactions, and …

Incorporating ecological networks and green infrastructure into spatial strategies: Mapping optimal locations for habitat banks
… spatial targeting of habitat banks, with ecological networks and ecoprofiles employed to guide their location. Ecological effects of bank composition, size and location were examined, combined with a network analysis to determine people's access to natural greenspace in the same area, and …

Microbiology of marine sponges: from community structure to symbiont function
… none of the applied core definitions altered ecological network structure summarising interactions among bacteria within the sponges. Sponge reefs often comprise an array of different and sometimes phylogenetically distant sponge species, with most of them hosting distinct microbial …

The Influence of Changing Nutrients and Warming on Phytoplankton and its Interactions with Zooplankton in the North Sea
… a weak positive effect. Information-theoretic network analysis indicates that plankton interactions at Helgoland Roads are highly sensitive to environmental conditions. Hybrid interaction strengths increase under low nutrient and light availability. Bottom-up strength (from primary producers to …
