A METACOMMUNITY FRAME WORK FOR INVESTIGATING THE SPREAD OF AQUATIC INVASIVES
The spread of Invasive species is one of the most pernicious and difficult-to-manage threats to aquatic biodiversity. Invasions and their effects are notoriously difficult to understand because they integrate processes across spatial scales and depend heavily on dispersal-driven dynamics of invaders. Applying metacommunity theory to the problem of aquatic invasions could be intensely profitable since metacommunity frameworks incorporate processes at multiple spatial scales, incuding processes driven by dispersal dynamics. Indeed, just such a framework for invasions was proposed by Howeth, Derry and Reitzel in 2010. Here we revisit the Howeth et al. framework as a tool for investigating aquatic invasions, suggest some modifications to the framework based on recent research, and then consider how application of the framework can be enlightening by applying it to two linked aquatic invasions: the invasion of non-native crayfish, and the simultaneous introduction of their non-native ectosymbionts. As we will demonstrate, the application of metacommunity frameworks to aquatic invasion scenarios can both reveal major drivers of invasion as well as generate predictions about rates and patterns.
