Aquatic invasive species (AIS) are a global problem, and Canada is no exception to the negative effects of biological invasions. As a management option, early detection of AIS is a cost- and time-effective strategy to mitigate ecological and economic impacts. However, the extensive length of the Canadian coastline at risk of invasions makes early detection a daunting task that requires focusing limited resources at the correct temporal and spatial scales. Determining the optimal scales and characterisation of environmental factors associated with the distribution of established AIS will help predict locations susceptible to future invasions. Another consideration for early detection is addressing the gaps in our knowledge about the ecology of AIS in their newly invaded habitats. These knowledge gaps can impede or delay efforts for early detection.
My over-arching research objective is to improve detection of invasive benthic invertebrates (e.g., ascidians, bryozoans, etc.) by examining the probability of AIS detection at different temporal and spatial scales, patterns of recruitment, and larval distribution and settlement. I hope that my research will contribute to early detection efforts by developing strategies that optimise the spatial scale for AIS sampling based on field observations and model predictions, shorten the temporal and spatial scales of sampling effort, and increase the probability of detection by targeting where propagules are most likely to be found. |
Les espèces envahissantes aquatiques (EEA) sont problèmatiques à l’échelle mondiale. Le Canada n’est pas à l’abri des effets négatifs provenant des invasions biologiques. Une option de gestion, la détection précoce de l'EEA, représente une stratégie d’efficacité en terme de coût/temps afin d’atténuer les impacts écologiques et économiques des EEA. Cependant, à cause de l’ampleur des côtes canadiennes soumises aux risques d'invasions, les tâches permettant la détection précoce sont plus ardues et nécessitent la concentration des ressources limitées à des échelles temporelles et spatiales appropriées. La détermination des échelles optimales et la caractérisation des facteurs environnementaux associés à la distribution de l'EEA établie aideront à prévoir les endroits les plus susceptibles d’invasion dans le futur. Une autre considération, quant à la détection précoce, est de se pencher sur les lacunes dans nos connaissances sur l'écologie de l'EEA dans son habitat nouvellement envahi. Ces lacunes dans les connaissances peuvent entraver ou retarder les efforts pour la détection précoce de l’EEA.
Mon objectif principal de recherche est d'améliorer la détection des invertébrés benthiques envahissants (par exemple les ascidies, les bryozoaires, etc.) en examinant la probabilité de détection de l’EEA à différentes échelles temporelles et spatiales, les modes de recrutement, ainsi que la distribution et la fixation des larves. Je souhaite que mes recherches puissent contribuer aux efforts de détection précoce en développant des stratégies qui optimisent l'échelle spatiale pour l’échantillonnage des EEA basé sur des observations de terrain et des prédictions par modélisation. Le but ultime étant de permettre de minimiser les échelles spatiales et temporelles des efforts d'échantillonnage, tout en augmentant la probabilité de détection en ciblant l’endroit où les propagules sont plus susceptibles de se trouver. |
