Ocean-surface heterogeneity mapping: exploiting hypertemporal datasets in support of seascape ecology research
Seascape ecology provides us with a framework to explore the distribution of marine life throughout the world’s oceans. Studies often require both biological and environmental data from a variety of sources, which are increasingly complemented by data acquired using remote sensing and …

Functional connectivity of coral reef fishes in a tropical seascape assessed by compound-specific stable isotope analyses
… connectivity among essential habitats at the seascape level. This thesis presents the development and first application of a method for tracking fish migration using amino acid (AA) δ13C analysis in otoliths. In a controlled feeding experiment with fish reared on isotopically distinct diets, …

A seascape genetics approach to exploring the phylogeographic response of marine fishes to late Quaternary climate change
… in marine ecology by taking an interdisciplinary seascape genetics approach to investigating the interplay of climate, dispersal and adaptation as shallow-water marine fishes respond to environmental heterogeneity over space and climatological shifts over time. [TRUNCATED]

Spatial, temporal and within-species variation in the foraging ecology of a marine predator across a dynamic seascape
… the Arctic marine environment – a dynamic seascape undergoing rapid climatic changes – across age, space and time using stable isotope analysis and animal satellite telemetry. I used a long-term dataset (1990 – 2013) of ringed seal muscle (n = 630) and liver (n = 558) samples, as well as …

… architecture. In pursuit of a vision in the seascape, initial drawings were made holding the notion of light and water. Later development of spaces was informed by these drawings. Pure drawing helps me not only with directly expressing what I imagine, but also furthering the design by …

Sea sparing, sea sharing, and production at least cost to the planet
… the benefits of no-take MPAs may be limited in seascapes that are already ‘well-regulated’ by other forms of fisheries management, particularly if they only displace fishing effort to other areas for no net biodiversity gain. In this thesis, I aimed to evaluate the conservation benefits of …

The challenge of creating an effective and equitable legal regime to cover transboundary protected areas considering the challenge through the lens of the Great Limpopo Transfrontier Park
… and integrated into the wider landscape and seascape.' Target 11 requires compliance with a number of preconditions, two of which will be discussed in this dissertation. First, well-governed protected areas provide an established mechanism for both safeguarding habitats and populations of …

Of His Bones are Coral Made: Submerged Cultural Resources, Site Formation Processes, and Multiple Scales of Interpretation in Coastal Ghana
… submerged archaeological sites within the Elmina seascape of coastal Ghana. Building on and intersecting with the work of other scholars, this research is a unique approach to the investigation of submerged cultural remains related to historical maritime trade. Remote sensing surveys in 2009 led …

Land/seascapes of exclusion: social order on the coastal margins
… enclave of Pauanui, it is shown that the land/seascape of coastal Aotearoa/New Zealand is gradually being disciplined through the design of coasts that are accommodating of a particular patronage. These ‘exclusive’ coasts appear in stark contrast to those places where an alternative social …

Half-finished streets, Illimitable Horizons and Enclosed Intimacy: the landscapes of Elizabeth Gaskells writing.
… featureless, treeless expanses of moorland and seascape with 'illimitable horizons'. Chapter 6 establishes the topographical security of Gaskell's fictionalised rural and provincial landscapes. It explores the extent to which lives are dominated by the 'enclosed intimacy' of their physical and …

An Assessment of Sea Turtle, Marine Mammal and Seabird Bycatch in the Wider Caribbean Region
… and geospatial analyses to assess the bycatch seascape for the region. I conclude that sea turtle bycatch in the WRC is significantly linked to turtle rookeries, especially those on the continental land mass and in the southern section of the Caribbean basin, in large part because of the near …

The Role of Backreef Soundscapes and their Spatial Structure for Recruitment of Tropical Marine Larvae
… the experiment within a large, relatively quiet seascape where local larval abundance may have been low. If so, then planktonic larvae may require a series of acoustic “sign-posts”, perhaps in combination with other cues (e.g., chemical), to successfully orient to distant nursery habitats. …

The effects of white shark presence on the behaviour of Cape fur seals at Geyser Rock, Gansbaai, South Africa
… rookeries to offshore foraging areas. The seascape around Geyser Rock is comparably more featured, including kelp beds and extensive shallow (5-10m depth) reef systems, whereas Seal Island is largely featureless, with neither extensive kelp nor reefs. At Geyser Rock, predations by white …

Population Genomics of the Sugar Kelp Saccharina latissima

Evaluating the Role of Habitat Complexity in Structuring Seagrass Communities

An Integrated Approach for Controlling Verticillium Wilt of Strawberry

Marine stressor and receptor interactions: A new approach to incorporate multiple stressor impacts into marine spatial management
