Life histories unfold within the ecological context of an organism's environment, and thus are intimately linked to organismal fitness. The evolution of alternate life history strategies, either within or between taxa, can profoundly affect ontogeny, ecology, and population dynamics. Many cnidarians (sea anemones, corals, jellyfish, etc.) exhibit complex life histories involving sexual reproduction and multiple modes of asexual reproduction. Sea anemones of the family Edwardsiidae exemplify t...

Leviathan and the other sea-monsters in the Hebrew Bible have been a source of dissension amongst biblical scholars. Evidently, no consensus exists amongst them on how to translate the Hebrew words referring to these mythical monsters. Therefore,atendency developed amongst exegetes to transfigure these mythical beasts into ordinary animals, to translate them in a vague and general way or to interpret them as mere symbols. This study, therefore, investigates ways in which the assumed existence ...

The Swedish Sea Rescue Society (SSRS) is a non-profit organization that performs sea rescue operations around Sweden’s coast line and lakes. In their sea rescue work, they came up with an idea that could be used to prevent accidents that are caused by harsh weather. According to Trafikverket, two out of three accidents at sea can be related to bad weather. Today, the SSRS have a weather application that you can download and note the weather where the different national weather stations are locat...

Coral reefs are among the most diverse marine ecosystems, but they are threatened by climate change. The foundation of reef ecosystems is the coral holobiont or metaorganism that consists of the coral animal host, photosynthetic microalgae, bacteria, and viruses (among other organisms). While microalgae provide the energy for corals to build the massive three-dimensional skeletons, bacteria support functions related to metabolism, immunity, and environmental adaptation. Conversely, the function ...

GIS was used to model the impacts of sea level rise (SLR) and hurricane storm surge scenarios on natural and built infrastructure. Social, gentrifica...

abstract: The ocean sequesters more than 25% of the carbon released by anthropogenic action every year, and oligotrophic oceans, such as the Sargasso Sea, are responsible for about 50% of the global carbon export. Pico- and nano-phytoplankton (cells < 5 µm), mostly unicellular eukaryotes (protists) and cyanobacteria, dominate the primary production in the Sargasso Sea; however, little is known about their contribution to the export of carbon into the deep ocean via sinking particles. The overall...

In South Africa the need to protect and manage the national water resource has led to the development of the Reserve as a basic right under the National Water Act (1998). The Ecological Reserve relates to the quality and quantity of water necessary to protect the sustainable functioning of aquatic ecosystems. The geomorphological contribution to setting the Reserve has focussed on three groups of information requirements: the spatial and temporal availability of habitat, the maintenance of subst...

The discovery of deep-sea chemosynthesis-based ecosystems including hydrothermal vents and cold seeps has greatly expanded our view of life on Earth. Nevertheless, for many benthic organisms in these ecosystems, little is known about where they come from, how scattered populations are connected by larval dispersal, and how they adapt to the local environments. Mussels of Bathymodiolus platifrons (Bivalvia: Mytilidae) are one of the dominant and foundation species in deep-sea chemosynthesis-based...

Climate change is a pressing issue caused by the systematic increase of greenhouse gasses (GHG). One way to avoid higher GHG emissions is through an increased use of public transportation, transitioning society away from the personal automobile. Public transportation is more sustainable than the personal automobile as its emissions per person are less and it takes up significantly less space. Sustainability is defined through the principle-based definition of the Framework for Strategic Sustaina...

The regime of islands, as captured in Article 121 of the United Nations Convention on the Law of the Sea (LOSC) grants a 200 nautical mile exclusive economic zone and continental shelf to all islands apart from "rocks which cannot sustain human habitation or economic life of their own." The provision was undoubtedly drafted in an intentionally ambiguous manner in order to strike a compromise between the contrasting views of States surrounding the regime of islands. Consequently, Article 121 is r...

<p> Saturn&rsquo;s moon, Titan, has been a scientific marvel since Cassini&rsquo;s flyby discovered methane-ethane lakes in the northern hemisphere. Several science missions to explore these lakes have been proposed, but none have been launched. Using these previous mission designs, as well as the success of the Huygens probe, this paper will discuss the development of a deployable multi-buoy system with the intent of studying the methane-ethane lakes. The buoys will study the chemical makeup of...

The upstream regulatory regions of numerous genes contain contiguous deoxyguanosine residues (G·C-rich sequences) which have been implicated in the regulation of gene expression, since they may involve alterations in their DNA structure, the binding of G-string factors and in some cases even the displacement of a nucleosome positioned over this area. A poly( dG).poly( de)-binding protein (suGF1) has previously been identified and purified on a small scale from embryonic nuclear extracts of the s...

In many gonochoristic fish, sex is plastic since it can be altered by the influence of environmental factors. In this thesis, using the European sea bass (Dicentrarchus labrax) model, a teleost fish with a polygenic sex determining system influenced by the environment, we have studied the effects of different environmental factors —including food supply, elevated temperatures and presence of estrogens— on growth, sex differentiation and gonadal development of juveniles. Global analysis of gene e...

The Adair Bay pozos (water holes) are small artesian springs scattered along the saltflats of the Gran Desierto near the coast of the Gulf of California in northwestern Sonora. The pozos provide essential fresh water for the rich bird fauna and some of the mammals, and were also utilized earlier by native people. The Gran Desierto aquifer appears to consist of sand and gravel deposited in ancient river beds which were subsequently overlain by dunes. Toward the coast, the alluvial aquifer becomes...

Hydroxylated polybrominated diphenyl ethers (OH-PBDEs) are naturally produced in aquatic ecosystems e.g. by algae. Many OH-PBDEs have been observed to be highly bioactive and to cause adverse effects through several pathways, e.g. via disrupting oxidative phosphorylation (OXPHOS). The levels of some OH-PBDEs have increased in Baltic biota over the past decades. This may be associated with the nutrient enrichment of the Baltic Sea, which has favored growth of some of the OH-PBDE producers. Cerami...

Sediment accumulated on a lakebed archives information about past climate and changes in the regional environment. Previous studies (Burgess, 2007; Koff, 2011; Palmer, 2012) in the Northeast Arm of Lake Champlain, specifically Missisquoi Bay and Saint Albans Bay, showed a period (~9,400 - 8,600 yBP) of elevated organic matter deposition in both bays, indicating a productive event that pre-dated any possible anthropogenic influence. However, the record was abruptly cut off and any documentation r...

Riverine organic (TOC, Total Organic Carbon) and inorganic (DIC, Dissolved Inorganic Carbon) carbon are the main sources of carbon in the Baltic Sea. While the importance of this contribution has been evaluated, there are currently several gaps in our knowledge of the mechanisms governing organic carbon dynamics in this region, especially for the particulate form, and the impact of future climate change on organic carbon transport. This licentiate thesis addresses this research deficit by (1) de...

A consequence of eutrophication in the Baltic Sea is growth of algae that accumulates in the coastal areas and beaches. Dense algal mats may cause anoxia or hypoxia and greatly reduce the recreational value of the area. Algae also functions as hyper accumulators of heavy metals and their metal levels may become toxic to higher trophic levels. The project Wetlands, Algae and Biogas (WAB) aims at removing algal beach cast for commercial use in biogas production and further use of the fermentation ...
