Thesis advisor: David Burgess / The contractile ring is pictured, analyzed, and even named under the basic assumption that the geometry of the structure begins and ends circularly and the ring is a single homogenous structure acting uniformly. However, under physiological conditions cell-to-cell adhesions force cells and therefore initial contractile rings into highly irregular and noncircular shapes. To investigate this basic assumption of contractile ring geometry, contractile ring shape of...

Thesis advisor: David Burgess / This doctoral thesis addresses two central topics divided into separate chapters. In Chapter 1: The cortical response to RhoA is regulated during mitosis, experimental findings using sea urchin embryos are presented that demonstrate that the small GTPase RhoA participates in positive signaling for cell division and that this activity is negatively regulated prior to anaphase. In a second series of experiments, myosin phosphatase is shown to be a central negative r...

Thesis advisor: Douglas Edmonds / Due to their low-lying position near the shoreline, river deltas are vulnerable to fluctuations in relative sea-level (RSL). Moreover, relatively little is known about fluvio-deltaic dynamics during RSL fall because the resulting deposits have low preservation potential. In this paper, I present a field-based study of the Goose River delta, coupled with numerical model simulations, that investigates the fluvio-deltaic response to RSL fall. The Goose River delta ...

Thesis advisor: Carling Hay / Modern day climate change is exacerbating sea level change both locally and globally. The magnitudes of these changes are dependent on numerous global and regional factors that make it difficult to accurately project local sea level into the future. In Alaska, there are many processes contributing to sea level changes along the coast. In particular, there is substantial vertical land movement, in the form of uplift and subsidence, due to the isostatic adjustment of ...

Thesis advisor: David R. Burgess / Polarity established by the first cleavages in sea urchin embryos was investigated in this thesis revealing precocious embryonic polarity. Studies of embryonic polarity have focused on protostomes such as <italics>C. elegans</italics>, and those on deuterostomes have focused on later developmental stages. I find asymmetries in the sea urchin membrane cell cortex as early as the first division after fertilization as a result of new membrane addition in the cle...

<p> Climate change has the potential to expose sea turtle nests to higher temperatures, which may negatively impact sea turtle hatchling vigor. In this study, loggerhead and green hatchlings were sampled from the Boca Raton, Florida beach and via lab incubation, and hatchling vigor was determined. Elevated nest temperatures decreased loggerhead and green turtle hatchling performance and corticosterone levels, with the most significant effects found in hatchlings exposed to maximum incubation tem...

博士 / 國立中央大學 / 地球物理研究所 / 94 / The South China Sea (SCS) is one of the marginal sea basins in the western Pacific area. The SCS is bounded by Eurasia continental crust in west, south and Manila Trench in east. In past two decade, several models were tried to describe the tectonic and its evolution of the SCS. Tapponnier et al (1986) proposed so-called “collision-escape” model to demonstrate the possible process of the opening of the SCS. Briais et al (1993) re-compiled then analyzed the magnetic d...

Accelerating sea-level rise (SLR) poses an imminent threat to salt marshes, which sit within meters of mean sea level. In order to assess marsh vulnerability to SLR, we must first understand the fundamental processes governing marsh response to SLR. The objective of this dissertation work is to examine how marsh sedimentation and erosion affect the morphological development of marshes as sea level rises, over a broad range of spatial and temporal scales. At the smallest scale, the effects of b...

Prokaryotes are the main actors in biogeochemical cycles that are fundamental in global nutrient cycling. The characterization of microbial communities and isolates can enhance the comprehension of such cycles. Potentially novel biochemical processes can be discovered in particular environments with unique characteristics. The Red Sea can be considered as a unique natural laboratory due to its peculiar hydrology and physical features including temperature, salinity and water circulation. Moreove...

Gravity waves are ubiquitous at the surface of the ocean and play a key role in the coupled ocean-atmosphere system. These wind generated waves, for which gravity provides the restoring force, influence the kinematics and dynamics of the upper ocean and lower atmosphere. Their breaking injects turbulence into the upper ocean, generates bubble plumes and sea-spray thus transferring energy, momentum, heat and mass between the atmosphere and the ocean. In the anthropocene, with CO2 driving the warm...

Saudi Arabia is highly accessible to marine water, receives year-round availability of sunlight and generates a high annual carbon dioxide emission, all of which are justifications that merits the deployment of cyanobacterial cell factories. However, industrial cyanobacterial strains capable of thriving in conditions of the Arabian Peninsula are currently lacking. Given the fact that native cyanobacteria from the Red Sea are adapted to the local conditions, they are therefore good cell fact...

Picoeukaryotes are protist 3 µm belonging to a wide diversity of taxonomic groups, and they are an important constituent of the ocean microbiota, performing essential ecological roles in marine trophic chains and in nutrient and carbon budgets. Despite this, the true extent of their diversity is currently unknown, and in the last decade molecular surveys have uncovered a substantial number of previously unknown groups from all taxonomic levels. No studies on this group have been done so far on ...

The Kingdom of Saudi Arabia is dependent on desalination of seawater to provide new water supplies for the future. Desalination is expensive and it is very important to reduce the cost and lower the energy consumption. Most seawater reverse osmosis facilities use open-ocean intakes, which require extensive pre-treatment processes to remove particulate and biological materials that cause operating problems. An alternative intake is the subsurface system which utilizes the concept of riverbank fil...

The starlet sea anemone, Nematostella vectensis (phylum Cnidaria, class Anthozoa), inhabits tidal marshes along the Atlantic coast of North America. These shallow coastal habitats are subject to extreme environmental variability, including fluctuating levels of reactive oxygen species (ROS). High ROS concentrations can be cytotoxic and lead to oxidative stress. Given the importance of tidal marshes for marine biodiversity and their susceptibility to oxidative stress, it is important to study how...

<p>Cnidarians are predators that use specialized stinging cells to produce cnidocysts. Cnidocysts are membrane-bound organelles consisting of a capsule and an eversible tubule. Cnidocysts are produced and employed for prey capture, defense, and attachment to substrates. Discharge of cnidocytes is regulated by mechanoreceptors called hair bundles. Hair bundles arise from hair cells and are used to detect vibrations from prey to maximize cnidocyst discharge for prey capture. Sea anemones are cnida...

Due to intensive coastal development, a combination of local (e.g. pollution, fishing) and global pressures (such as climate change) is affecting marine habitats worldwide. This is a pressing issue in Saudi Arabia, particularly considering the plans for the expansion of sea-related activities within the Saudi Arabia's Vision 2030 framework. Sustaining some of those activities, such as tourism, is dependent upon the maintenance of good ecosystem health. National monitoring programs in Saudi Arabi...

La dégradation de la matière organique terrestre intrigue les scientifiques depuis des décennies. Si l’on a longtemps cru qu’elle était réfractaire à toute dégradation en mer, il a finalement été démontré que la signature en matière organique terrestre dans les sédiments côtiers était très faible. Afin de mieux comprendre ces processus de dégradation, il est crucial d’étudier leur activité de manière globale, et d’essayer de déterminer les mécanismes en jeu.Grâce à un éventail de traceurs lipidi...
