Environmental Change in Ovid's Poetry
What does Ovid tell us about how humans have changed the world? This thesis argues that a narrative of culture’s impact on nature—habitually invoked by scholars to describe this process—does not do justice to the subtlety and complexity of Ovid’s poetry. Reading Ovid requires thinking of …

Disentangling plant-microbe interactions under environmental change
… provide for a growing population under climate change pressures with higher intensity droughts occurring more frequently. However, such manipulations alter soil health, lowering carbon: nitrogen (C:N) ratios and shifting plant-microbial interactions, on which plants are largely dependent. This …

Youth-adult Partnerships Creating Positive Environmental Change
When youth create positive environmental change in their communities they typically act with adult guidance. The role of adults, however, is largely absent in literature around youth participation in environmental action. This research explored through phenomenological interviews with 33 …

Impact of environmental change on ecological communities.
The impacts of environmental change on ecological communities are poorly understood relative to impacts on species. Impacts on inter-community (beta-) diversity are particularly neglected. As a result, our ability to forecast the impacts of environmental change on communities, and on individual …

Interpreting environmental change using bivalve shell geochemistry
… proxies are used to infer how climate has changed throughout Earth’s history. Examined herein are two such geochemical proxies—the δ¹⁸O of the shell of the Australian mud or flat oyster, Ostrea angasi, and the Mg/Ca ratio of the shells of the Sydney Rock oyster, Saccostrea glomerata, and …

Late-quaternary environmental change at Eastbourne, East Sussex
… deterioration and its possible use for palaeoenvironmental reconstruction to be attempted. The late-Flandrian vegetation reveals the impact of both anthropogenic factors and coastal changes. The pattern of Flandrian coastal/sea-level change has been reconstructed through an examination of …

Past Environmental Change On The Eastern Andean Flank, Ecuador
… pressures and both current and projected climate change. This thesis examines the palaeoecological history of two stratigraphic sequences (Mera Tigre West [MTW] and Mera Tigre East [MTE]) obtained from the Ecuadorian modern lower montane forest. The sediments preserved were analysed using eight …

Conversations: the socially engaged artist as environmental change agent
Conversations: The socially engaged artist as environmental change agent Janey Hunt - University of Plymouth 2005- 2011 I use my art practice in conjunction with environmental behaviour research and Michel de Certeau’s practice of the everyday, to enable a re-examination of socially engaged art and …

Mangroves, fisheries and coastal communities’ perception of environmental change
… for the survival of many economically and environmentally vulnerable communities around the world, including fishing communities. With over 1.3 billion people living nearby tropical coasts, healthy ecosystems are crucial for sustaining the ecosystems services that these communities depend …

The Impacts of Disruptive Environmental Change on Vital Microbial Ecosystems
… and carbon cycles that influence climate change and our modern environment, and are in turn influenced by environmental change. Through resource acquisition, metabolism, symbiosis with plants and other organisms, and functional & taxonomic composition, microbial communities determine …

Response to environmental change by bacterial communities in stream biofilms
… that bacterial community composition would change monthly/seasonally in accordance with an annual cyclical trend and that regional environmental factors would be significant drivers of the observed community change. Bacterial 16S rRNA gene sequencing of these samples revealed that stream …

Evolutionary perspectives on plant responses and sensitivity to environmental change
Global change is putting unprecedented pressure on plants to adapt or migrate to avoid extinction. Studying the past responses of plants to environmental change can shed light on the potential evolutionary outcomes and sensitivity of species to future environmental change. These processes are …

An environmental change detection and analysis tool using terrestrial video
… developed a prototype system to detect and flag changes between pairs of geo-tagged videos of the same scene with similar camera trajectories. The purpose of the system is to help human video analysts detect threats within a set of videos. While computers cannot differentiate threat from …

Spatial urban environmental change and Malaria/Diarrhoea mortality in Accra, Ghana
Introduction and Theoretical Background: Environmental change processes, including demographic and climate change, have been widely predicted to have profound consequences (both direct and indirect) on human health. There is a strong consensus that such health impacts of environmental change would …

Modelling migration and aggregation: Applications in fisheries, environmental change, and evolution
… due to fisheries exploitation compounded by environmental change. Many species exhibit seasonal migratory homing behaviour to and from spawning grounds. In this thesis, models are developed to explore the consequences of migratory behaviour and spatial structure on fisheries management and …

Urban Restoration Ecology: Investigating environmental change, ecological function, and enrichment planting
… such as forests, it is unclear how dynamics change after planting and over the long-term, and hence what best management practices should be used in the decades following initial plantings. This thesis addresses these knowledge gaps through three separate studies on restored urban forests. …
