Intertidal populations of the sea urchin Parechinus angulosus were examined at seven sites along the south and east coasts of South Africa. At the five southerly sites, P. angulosus occurred in allopatry, while, at the two northerly sites, it occurred in sympatry with several species of Indopacific sea urchins. At the five southerly sites, there was a significant correlation of number of sea urchins per pool with the surface area of the overhang in that pool. This relationship broke down for P. ...

While geographic distance is a variable often used to explain population genetic differentiation, dynamic processes leading to stochastic population structure are more likely driving factors. The following thesis presents the population structure of a common reef sponge, Stylissa carteri, and yields hypotheses on the influence of environmental heterogeneity as a predictor of the observed population structure. This project represents the largest population genetics study thus conducted in the Red...

<p> The South China Sea has long been a region of competition and tension. In the Spratly Islands alone, Brunei, China, Malaysia, the Philippines, Taiwan, and Vietnam maintain disputing claims to the region&rsquo;s land features and surrounding maritime territories. Some argue that ongoing negotiations between China and the Philippines toward joint explorations of one of these disputed regions could be the key to promoting greater cooperation amongst the other claimants. These arguments, however...

>Magister Scientiae - MSc / Sea anemones (Order Actinaria) are a diverse order from the Class Anthozoa. They are found in all marine habitats at all depths and their symbiotic relationships play an important role in energy transfers especially in the benthic-pelagic community. The evolutionary background and phylogenetics of the class is poorly understood due to a lack of correspondence between taxonomic and molecular data (Daly et al. 2008). Therefore, a deeper exploration into Cnidarian molecu...

Although the Red Sea presents a unique environment with high temperature and salinity, it remains an area that is understudied. This lack of information is reflected in many areas, one which is biodiversity. Despite increasing work on biodiversity throughout the Red Sea and an increase in Cephalopoda studies, Cephalopoda in the Red Sea remain underrepresented, which is especially pronounced in molecular analyses. Members of the class Cephalopoda are considered to be major contributors to coral r...

The purpose of this essay is to look into how Jean Rhys describes the complexity of colonialism in the Caribbean and how it affected the colonized people and the European colonizers. Her novel Wide Sargasso Sea is considered to be a re-writing of Jane Eyre, but it also demonstrates social rankings and racial groupings in the colonial society. She does not only describe Mr. Rochester’s first wife, she also depicts the forbidden love story between Antoinette and her “coloured” cousin Sandi. The an...

The wave energy converter developed at Uppsala University consists of a linear generator at the seabed driven by the motion of a buoy on the water surface. The energy absorbed by the generator is negatively affected by variations of the mean sea level caused by tides, changes in barometric pressure, strong winds, and storm surges. The work presented in this doctoral thesis aims to investigate the losses in energy absorption for the present generation wave energy converter due to the effect of se...

<p> Bamboo corals are a family (Isididae Lamouroux, 1812) of cnidarian anthozoans in the subclass Octocorallia. They are distinct and easily recognizable because of their unique articulating skeleton, which alternates internodes of calcium carbonate with proteinaceous sclerite (microscopic skeletal elements)-free nodes, and which is currently the primary synapomorphy for the family. Isididae is further divided into four subfamilies (Circinisidinae, Isidinae, Keratoisidinae, Mopseinae) based on s...

During 1998-2012, climate change and sea level rise (SLR) exhibit two notable features: a slowdown of global surface warming (hiatus) and a rapid SLR in the tropical western Pacific. To quantify their relationship, we analyze the long-term control simulations of 38 climate models. We find a significant and robust correlation between the east-west contrast of dynamic sea level (DSL) in the Pacific and global mean surface temperature (GST) variability on both interannual and decadal time scales. B...

Wind and waves play a major role in important ocean dynamical processes, such as the exchange of heat, momentum and gases between atmosphere and ocean, that greatly contributes to the earth climate and marine lives. Knowledge on wind and wave weather and climate is crucial for a wide range of applications, including oceanographic studies, maritime activities and ocean engineering. Despite being one of the important world shipping routes, the wind-wave characteristics in the Red Sea are yet to be...

World oceans cover more than 70% of the earth surface and constitutes a major sink of atmospheric CO2. Two of the most important gases in the marine carbon cycling are O2 and CO2 and hence accurate descriptions of the air-sea gas exchange of these gases are crucial. Still there is a lack of knowledge of the relative importance of processes controlling the efficiency of the air-sea gas transfer. This is especially true for Arctic and high latitude seas were studies on air-sea gas exchange are few...

Changes in the level of closed lakes such as the glacial Lake Lisan/Near East, that occupied the Jordan Rift Valley between 80 to 15 ka BP, reflect climatic changes in evaporation and precipitation patterns. However, in an actively subsiding basin such as the Dead Sea (water level today is at -423 m relative to mean sea level), tectonic activity could also contribute to lake level recession. The retreat of Lake Lisan left behind a sequence of shoreline terraces and deposits of aragonite and gyp...

Sea ice is a vital component of the cryosphere and does not only influence the polar regions but has a more global influence. Indeed, sea ice plays a major role in the regulation of the global climate system as the sea ice cover reflects the sun radiation back to the atmosphere keeping the polar regions cool. The shrinkage of the sea ice cover entails the warming up of the oceans and as a consequence, a further amplification of the melting of sea ice. Therefore, the polar regions are sensitive t...

Cyanobacteria are widely distributed in marine, freshwater and terrestrial habitats. Some cyanobacterial genera can convert di-nitrogen gas (N2) to bioavailable ammonium, i.e. perform nitrogen (N) fixation, and are therefore of profound significance for N cycling. N fixation by summer blooms of cyanobacteria is one of the largest sources of new N for the Baltic Sea. This thesis investigated N fixation by cyanobacteria in the Baltic Sea and explored the fate of fixed N at different spatial and te...

Eutrophication is a consequence of excess nutrients in the water which leads to increased algaegrowth, reduced water transparency and hypoxic bottoms. This is the biggest environmental problemfor the Baltic Sea which recently has resulted in stricter legislations and other initiatives to help theBaltic Sea to recover. However, the actions to reduce the nutrient input to the Baltic Sea have so farmainly been land-based. These actions seem to not be enough since the eutrophication continues tobe a...

Deep-sea hydrothermal vents have been intensely studied since their discovery almost 30 years ago. These environments have been shown to harbour previously unknown organisms, which depend on chemosynthetic prokaryotes for much of their nutrition. Although high abundances of free-living prokaryotes have been documented from many hydrothermal vent sites, the fate of prokaryotic biomass has not been well studied. The initial goal of this thesis was to determine the abundance and distribution ...

Otariids such as the Steller sea lion (Eumetopias jubatus) are among the most manoeuvrable of marine mammals (expressed as a minimum turning radius and speed during manoeuvres). They evolved in terrestrial and aquatic environments that are structurally complex, and feed on prey that are an order of magnitude smaller than themselves. Compared to other aquatic organisms, Steller sea lions have an unstable body design and are presumed to invoke swimming techniques that reflect their need to be...
