A crucial step in characterizing the potential risk posed by non-native species is determining whether a potential invader can establish in the introduced range and what its potential distribution could be. To this end, various environmental models ranging from simple to complex have been applied to predict the potential distribution of an invader, with(More)
Invasive species possess unique traits that allow them to navigate the invasion process in order to establish and spread in new habitats. Successful hull fouling invaders must resist both physical and physiological stressors associated with their voyage. We characterised attachment strength and drag coefficient of common fouling species in order to estimate(More)
1. The most effective way to manage nonindigenous species and their impacts is to prevent their introduction via vector regulation. While ships' ballast water is very well studied and this vector is actively managed, hull fouling has received far less attention and regulations are only now being considered despite its importance for introductions to(More)
A qualitative biological risk assessment for vase tunicate Ciona intestinalis in Canadian waters: using expert knowledge. – ICES Journal of Marine Science, 65: 781 – 787. Non-indigenous species (NIS) can pose a significant level of risk, through potential ecological or genetic consequences, to environments to which they are introduced. One way to(More)
Manuscript reports contain scientific and technical information that contributes to existing knowledge but which deals with national or regional problems. Distribution is restricted to institutions or individuals located in particular regions of Canada. However, no restriction is placed on subject matter, and the series reflects the broad interests and(More)
Global patterns show that estuaries are more invaded than open coasts and artificial habitats are more invaded than natural ones. The contention that artificial habitats in estuaries are more invasible than other habitats may result from variation in propagule supply, however, as artificial habitats are closely linked to vectors of non-native propagules,(More)
Screening-level risk assessment tools for non-indigenous species are useful to inform management and policy decisions. While a number of tools have been developed to evaluate the risk of introductions in terrestrial and freshwater environments, only one tool is available for marine invertebrates [Marine Invertebrate Invasiveness Scoring Kit (MI-ISK)] and it(More)
