Abstract:

The objective of this thesis is to update the Mori-Butterworth (2006) model of the krill-predator dynamics of the Antarctic ecosystem. Their analysis aimed to determine whether predator-prey interactions alone could broadly explain the observed population trends of the species considered in their model. In this thesis, the Antarctic ecosystem is outlined brie y and details are given of the main krill-eating predators including whales, seals, fish and penguins, together with an historical record of the human harvesting in the region. The abundances and per capita krill consumption of the krill-

Abstract:

With growing human pressures on the oceans and seas, the resulting decline of ecosystem health and biodiversity is increasingly limiting the ability of marine ecosystems to provide essential functions and resources for human wellbeing. To prevent further marine degradation, an ecosystem based approach to marine management is needed. An integral part of this is constructive stakeholder engagement. However, in a marine context, engagement is often difficult due to traditionally sectoral management and the complexity of marine issues. This thesis presents an interdisciplinary study that evaluates

Abstract:

Ecosystem restoration and management seek to repair, improve, or maintain a suite of desired environmental conditions for a specific ecosystem. However, when working on complex ecosystems, where do you start and how can you tell when you are successful? Forecasting ecological effects of restoration scenarios provides a basis for project evaluation and selection of restoration alternatives. Ecological monitoring is essential for assessing ecosystem condition over time. In an integrated approach to adaptive management a forecasting model simulates system response and is validated by monitoring p

Externalities caused by human transformations in ecosystems structure and functioning has been threatening environmental quality and social welfare in all socioecological systems, including coastal zones. Environmental Impact Assessment (EIA) is an instrument widely used to evaluate the feasibility of developments and projects that can potentially provoke changes in biophysical-human environment. However, EIA generic and fragmented approach has not properly been considering people and environmental particularities, such processes and benefits to society, in decision making.

Abstract:

Ocean acidification and warming have been shown to affect a wide range of marine organisms and impact assemblages and ecosystems. Many of the species experiencing negative biological effects provide valuable ecosystem services, yet it is unclear how these biological effects will affect ecosystem services provision. This thesis aimed to appraise the consequences of ocean acidification and warming on important shellfish species, from physiology to provision of ecosystem services, using a multidisciplinary approach. The responses to ocean acidification and warming of two ecologically and commerci

L'Analyse de Cycle de Vie (ACV) est un outil d'évaluation des impacts environnementaux. Il s'agit d'un outil robuste, souvent utilisé en éco-conception. Il permet de prendre en compte des impacts globaux, à toutes les étapes du cycle de vie d'un produit, « du berceau à la tombe ». Actuellement, cette méthode ne permet pas la prise en compte des impacts de l'occupation et de la transformation de l'espace par l'homme en milieu marin. Ce travail de thèse est donc le développement d'une nouvelle catégorie d'impact en ACV pour pallier ce manque : le "sea use". Dans la mesure où peu d'études avaient

Oregon's ocean waters are a potential source of wind, wave, and tidal energy; of interest to renewable energy entrepreneurs and to the U.S. government as it seeks to bolster energy security. In order to install technology to capture this energy, however, it may be necessary to mitigate conflict with existing ocean space users. The objective of this research was to construct a conflict analysis model in a GIS to answer the following research questions: (1) Within the study area off the coast of Oregon, where are stakeholders currently using ocean space and how many uses overlap?

Abstract:

Informing marine planning and the management of species at ecosystem-scales is difficult because data are generally lacking at that scale. Collecting empirical information on the distribution and/or abundance of species across broad spatial scales is expensive and logistically difficult. Accurate and efficient monitoring programmes that assess the response of species to management actions often cannot be conducted at ecosystem-scales due to time, expertise and cost constraints.

Abstract:

Estuaries and other transitional waters are complex ecosystems critically important as nursery and shelter areas for organisms. Also, humans depend on estuaries for multiple socio-economical activities such as urbanism, tourism, heavy industry, (taking advantage of shipping), fisheries and aquaculture, the development of which led to strong historical pressures, with emphasis on pollution. The degradation of estuarine environmental quality implies ecologic, economic and social prejudice, hence the importance of evaluating environmental quality through the identification of stressors and impact

Abstract:

Effective monitoring of marine ecosystems and the redistribution of marine species globally from climate change, overfishing, and other anthropogenic pressures require robust methods for quantifying species, the types of assemblages, and their spatial distributions throughout time. SCUBA diver-based methods that have traditionally been used to monitor these impacts are limited by deep-water (~>35 m) and turbulent environments. This has led to a poor understanding of many remote, offshore ecosystems and marine reserves. Remotely operated vehicles (ROVs) are a novel approach to deep-water survey
