Thesis (MSc)--Stellenbosch University, 2013.<br>ENGLISH ABSTRACT: Alien invasive species are a global concern not only threating biodiversity, but also negatively impacting regional economies. Consequently research aimed at understanding the invasion process is crucial for management of invasive alien species to reduce these impacts. Identifying accurate natal ranges is the key first step for efficient alien plant management, especially biological control. Such knowledge may assist in selecting host-specific biological control agents and help prevent non-target impact on native speci

Les espèces exotiques envahissantes sont un sujet de préoccupation grandissant, mais sont-elles,pour le droit international, un objet comme un autre ? Une espèce exotique envahissante a comme particularité d’être une espèce vivante qui, par sa seule présence dans un écosystème qui lui est étranger, va engendrer des effets délétères alors qu’elle n’en aurait causé aucun dans son écosystème d’origine. Le droit de la mer est-il armé pour répondre à cette menace ? La question de la qualification de leur atteinte en droit international et plus précisément en droit de la mer est autant novatrice que

Cependant, elles ne possèdent pas un temps de vie suffisamment long pour atteindre directement la stratosphère. Les VSLS se dégradent au cours de leur transport, conduisant à des composés intermédiaires, les gaz produits (PGs).

Abstract:

The transportation of organisms in the ballast water of cargo ships has been recognized as a source of invasive species despite current control measures. Pathogenic bacteria in the ballast tank have been studied but the total diversity of the ballast tank bacterial community has not been examined. This study is the first to characterize the total bacterial community within a ballast tank by constructing a clone library from a ballast water sample from a cargo ship in the Port of Houston, amplified ribosomal rDNA restriction analysis (ARDRA) and phylogenetic analysis.

Abstract:

An average of three to five billion tons of ballast water (BW) is transported globally per year; 79 million tons of which is released into U. S. waters. Ballast water is necessary for large ships to maintain balance and stability while loading and unloading cargo as well as during transit. As a ship unloads it’s cargo at a port, it takes on ballast water and then when it loads cargo at the next port, it discharges the ballast water, thus transferring water from port to port. Aquatic organisms are transported around the globe via ballast water. These organisms can potentially cause serious envi

Abstract:

With steady growth in global commerce and intensified ship traffic worldwide, comes the increased risk of invasion by non-indigenous organisms. Annually, >7000 vessels traveled across Galveston Bay, Texas from 2005-2010. These vessels discharged ~106 million metric tons of ballast water, equivalent to ~3.4% of the total volume of the Bay. A majority of these discharging vessels originated from around the Gulf of Mexico and the Caribbean Sea. By evaluating the source and frequency of inoculations from various locations, we are striving to assess the invasibility risk to Galveston Bay by way of

Abstract:

The worldwide transfer of non-indigenous invasive aquatic organisms via ships' ballast water and shellfish translocation has been widely shown to cause significant ecological, economic and human health impacts. In 2004 the International Maritime Organisation (IMO) adopted the International Convention for the Control and Management of Ships' Ballast Water and Sediments. This legislation (still to be ratified) requires all ships to introduce by 2016 approved systems capable of treating ballast water to strict microbial standards. The latter has reinvigorated interest in the application of
