Isla del Rey : a marine biology center
In our changing times many of our necessities have geared us to search for new spaces that can accommodate them. This thesis attempts to devise the use and expansion of a distinguished 18th Century building dominating a small island, Isla del Rey; in the deep sea port, Port de Mao, of Menorca. The …

The edge observed : island landscape for a marine biology facility
… one another and to their site. The design of a Marine Biology Facility on an island affords an opportunity to test out and explore the observation studies. The island exists in a landscape context that has clearly defined edge conditions. A harmony is sought that interprets the natural landscape …

Nemo's Plight: Political Economy, Green-Cultural Criminology, and Fish Abuse
<p>Using the Marine Aquarium Fish Trade as a case study, I propose an integrated theoretical framework in green criminology that strengthens the political economic "treadmill of production" theory (see Lynch et al., 2013) by incorporating an analysis of the "cultural grease" that ensures the …

Battery-Free Subsea Internet-of-Things
… applications (across climate/weather modeling, marine biology, aquaculture, and defense). However, standard IoT technologies (e.g, Bluetooth, WiFi, GPS) cannot operate underwater, which has left 70% of our planet (the ocean) beyond their reach. In this thesis, I describe how we can change this …

Rocky Shores: From Habitat Threat to Marine Awareness & Well-Being Benefits
… coastal areas. However, research within Marine Biology has shown that such visits can harm natural habitats. Consequently, this thesis uses an integrative approach to examine both the risks to the environment and benefits to the human visitors in the context of rocky shores (intertidal …

Biodiversity, distribution patterns and trophic position of meiobenthos associated with reduced environments at continental margins
… became one of the most important events in marine biology of last decades. The variable reduced environments share common features such as high content of reduced compounds (sulphides and hydrocarbons), often oxygen deficiency, high abundance and metabolic activity of bacterial populations, …

Synthesis and Evaluation of Naturally Occuring Halogenated Bipyrroles in a Relevant Marine Species, Fundulus Heteroclitus
… be biogenic in nature, derived from evidence of marine natural products that are persistent in the environment and widespread in the Pacific and Atlantic Ocean. The HDBPs exhibit chlorinated and brominated substitution patterns that closely resemble anthropogenic pollutants like the …

On optical and physical properties of sea ice in the Baltic Sea
… its properties have influence to many aspects of marine biology, climate and seafaring. This thesis is concentrated on describing physical and optical properties of landfast ice, and also pack ice, in the Baltic Sea. The aim of the thesis is to use measurements to study the interactions between …

Integrating Research into Conservation: Using Satellite Telemetry and Population Monitoring to Inform the Management of Hawksbill Turtles in Brazil
Marine ecosystems are increasingly threatened by human activities, highlighting the urgent need for effective conservation strategies. This dissertation focuses on the hawksbill turtle (Eretmochelys imbricata) in Brazil as a case study to enhance marine conservation efforts. Recognized as keystone …

FLORIDA RED TIDES FROM A SCIENTIFIC AND PUBLIC INFORMATION PERSPECTIVE
… dynamics work synergistically with G. breve biology. The potential use of chaos theory and fractals to help define a bloom and understand nonlinear bloom dynamics was also proposed. The historical newspaper analysis revealed many inadequacies in the red tide coverage. More than 500 articles …

Effects of Barotrauma on Four Species of Pacific Rockfishes (<i>Sebastes Spp.</i>)
<p>Physoclistic fish, such as Pacific rockfishes (genus <em>Sebastes</em>), have closed swim bladders that help them regulate their buoyancy. When anglers catch these fish and reel them to the surface, gases within their swim bladder expand due to the decrease in pressure. This can cause their swim …

Patterns in the landed catches and determinants of catch composition in the South African inshore trawl fishery
The inshore trawl fishery, which nominally targets Merluccius capensis (shallow water hake) and Austroglossus pectoralis (east coast sole), has the second highest bycatch rate of all South African fisheries. For over one hundred years there has been concern about the sustainability of the harvests …

Movement behaviour of the Green Jobfish (Aprion virescens), the Potato Bass (Epinephelus tukula) and the Giant Trevally (Caranx ignobilis), on South Africa's coral reefs
… were studied to provide information for marine spatial planning and to understand their ecological roles on South Africa's coral reefs. The three species were expected to display contrasting movement behaviour and to place different demands on spatial management strategies. The three …

The development of a marine antifouling system using environmentally acceptable and naturally occurring products
… combine two disparate areas of research namely marine biology and surface engineering, to develop a novel natural product (NP) based antifouling system. The overall objective of this thesis is to transfer a natural marine biological defence mechanism into an engineered antifouling coating …

The application of electro-analytical techniques to sea water analysis
… may be of considerable significance. In marine biology, inter alia, a knowledge of the cheinical nature of the waters is required. In this case considerable emphasis is laid on analysis such as the determination of phosphate, organic nitrogen, carbonaceous matter 8cc. Within the field of …

Patterns of evolution in a young species, the Baltic seaweed Fucus radicans
… is one of the most fundamental processes in biology, yet poorly understod. It is generally argued to build on a slow accumulation of differences between populations living in allopatry, but the formation of F. radicans most likely occurred without geographic separation and provides a unique …

Morphological, ecological and molecular examination of the seacucumber species along the Red Sea coast of Egypt and Gulf of Aqaba : with the investigation of the possibility of using DNA barcoding technique as a standard method for seacucumber ID
In this study the ecology, biology and classification of the sea cucumber species of the Red Sea coast of Egypt and Gulf of Aqaba were examined in order to resolve some of the long standing question on the identification and classification of sea cucumber.The introduction of the new barcoding …

Explaining the Variability of Free-Living and Attached Bacterioplankton Abundances in the Bay of St. Louis, Mississippi
<p>The Bay of St. Louis (BSL) is a shallow and vertically well-mixed estuary on the Gulf Coast of Mississippi and supports the recreational and commercial activities of the surrounding towns of Bay St. Louis, Diamondhead, DeLisle, and Pass Christian. In addition to residential communities, various …
