Larval dispersal and population connectivity: implications for offshore renewable energy structures
… the coast, such as MREDs, suggesting that the connectivity of these adult populations may be enhanced. Together, larval morphology, vertical positioning, and the coastal proximity of adult habitat could serve as useful indicators of larvae capable of reaching nearby newly installed offshore …

Exploring population connectivity and adaptation in two deep sea fishes, Molva molva and Molva dypterygia
… fisheries, it is important to better understand population structure and connectivity of these deep-sea populations, in order to ensure their sustainable management. In this study, samples of two deep sea species collected across their distribution range were screened: the common ling, Molva …

Pelagic dispersal and population connectivity of the green-lipped mussel (Perna canaliculus) in the Bay of Plenty
An understanding of the pelagic dispersal and connectivity in wild mussel populations is important for their sustainable management and for guiding the harvesting of wild seed for the mussel aquaculture industry. However, due to the complexity of the larval dispersal process, most studies have been …

Mapping pathogen distributions and population connectivity of a sentinel Arctic species, the polar bear (Ursus maritimus) across a changing North American Arctic
… on northern peoples and ecosystems, I quantify population connectivity and pathogen presence in a sentinel Arctic species, the polar bear (Ursus maritimus). Polar bears are apex predators that can provide insight into pathogen distribution and prevalence across marine and terrestrial ecosystems. …

The epidemiology of Lagos bat virus and henipaviruses in straw-coloured fruit bats (Eidolon helvum), using population genetics to infer population connectivity
… on the movement ecology of the species and connectivity of populations across its range was required. A multifaceted approach, using techniques from the field of genetics, population ecology, and virology, was used to understand the ways in which the structure and dynamics of fruit bat …

The genetic structure of New Zealand's coastal benthos: using the estuarine clam Austrovenus stutchburyi, to determine rates of gene flow and population connectivity
… process that benthic taxa can found new populations, colonise disturbed or degraded habitats and achieve genetic exchange between geographically separated subpopulations. While it is widely accepted that the dispersal process is important in determining the dynamics of many marine …

Trait-based modeling of larval dispersal in the Gulf of Maine
Population connectivity is a fundamental process that governs the spatial and temporal dynamics of marine ecosystems. For many marine species, population connectivity is driven by dispersal during a planktonic larval phase. The ability to obtain accurate, affordable, and meaningful estimates of …

Population Dynamics and Connectivity Patterns of Adfluvial and Stream-Resident Cutthroat Trout
Information about population dynamics, life history variation, and connectivity patterns of threatened cutthroat trout (O. clarkii spp.) is critical for effective management and restoration. The Lahontan cutthroat trout (O. c. henshawi; LCT) is classified as threatened under the Endangered Species …

Foraging ecology and population structuring of baleen whales in the western South Atlantic and eastern South Pacific
… migration, foraging localities, prey choice and population connectivity of whales in the Southern Hemisphere as they recover, the impact of these populations on marine ecosystems, and how they are likely to respond to the ongoing climate crisis. Historic information on population connectivity, …

Distribution, growth, and transport of larval fishes and implications for population dynamics
… stages of marine fishes play a critical role in population dynamics, largely due to their high abundance, high mortality, and ease of transport in ocean currents. This dissertation demonstrates the value of combining larval data, collected in the field and the laboratory, with model simulations. …

The spatial ecology and behaviour of the broadnose sevengill shark (Notorynchus cepedianus) in South Africa
… patterns in coastal presence, movement and population connectivity were then investigated for both sexes and a range of sizes of N. cepedianus in South Africa using acoustic telemetry, and a national scale array of acoustic receivers (the Acoustic Tracking Array Platform). Finally, an array …

Behavioral responses of invertebrate larvae to water column cues
… and exchange of individuals between adult populations. Historically, larvae were considered passive drifters in prevailing ocean currents. More recently, however, the paradigm has shifted toward active larval behavior mediating transport in the water column. Larvae in the plankton encounter …

Spatial Ecology and Movement Patterns of Black Drum (Pogonias cromis) and Sheepshead (Archosargus probatocephalus) in Mississippi Sound
… including patterns of residency, movement, and connectivity within northern Gulf estuarine systems. This study is the first to quantity subsystem-level use of these species in Mississippi Sound and assess the extent of individual variability in movement, connectivity, and reproductive-related …

Genetic Diversity of Blue Wildebeest (Connochaetes taurinus) in the Liuwa Plain of Zambia
… the amount of genetic diversity present in a population, connectivity between populations, and historical demographic changes. The blue wildebeest (<em>Connochaetes taurinus</em>) plays an important ecological role in many African savanna ecosystems, but little is known about the level of …

Metapopulation dynamics of the softshell clam, Mya arenaria
In this dissertation, I explored metapopulation dynamics and population connectivity, with a focus on the softshell clam, Mya arenaria. I first worked towards developing a method for using elemental signatures retained in the larval shell as a tag of natal habitat. I designed and implemented an …
