Minimizing invasion risk by reducing propagule pressure: a model for ballast- water exchange
© The Ecological Society of America www.frontiersinecology.org B invasions, a major and increasing agent of global biodiversity change, are often the result of inadvertent releases from trade and travel pathways (Levine et al. 2003; Ruiz and Carlton 2003; Drake and Lodge 2004). Empirical and theoretical evidence indicate that invasion risk can be decreased by reducing propagule pressure, specif...
متن کاملRelationship between propagule pressure and colonization pressure in invasion ecology: a test with ships' ballast.
Increasing empirical evidence indicates the number of released individuals (i.e. propagule pressure) and number of released species (i.e. colonization pressure) are key determinants of the number of species that successfully invade new habitats. In view of these relationships, and the possibility that ships transport whole communities of organisms, we collected 333 ballast water and sediment sa...
متن کاملSimulation of gamma irradiation system for a ballast water treatment
ABSTRACT Background: Invasion by different kinds of ballast water microorganisms is one of the most important marine environment problems around the world therefore preventing the invasion of these unwanted and harmful stowaways is one of the main strategies of responsible agencies. Some of these methods such as ocean excha...
متن کاملHigh colonization and propagule pressure by ship ballast as a vector for the diatom genus Pseudo-nitzschia
Most harmful diatoms belong to the marine, planktonic genus Pseudo-nitzschia and are responsible for amnesic shellfish poisoning through the production of domoic acid. Fifteen Pseudo-nitzschia species, nine of them toxigenic (approximately 60% of the species found in our samples) were recovered from 185 ship ballast tanks (water and sediment) destined for Canadian ports. Our results demonstrate...
متن کاملEfficacy of open-ocean ballast water exchange: a review
A literature search was conducted to summarize studies that quantified the efficacy of ballast water exchange. Here, a number of parameters were collated from 68 studies to provide a meta-analysis of the efficacy of exchange. The percent removal of ballast water, organisms, and various physical parameters was investigated to quantify exchange efficacy in terms of volumetric, biological, and wat...
