Background information and definitions
Non-native, invasive and other problematic species can impact on native subtidal benthic invertebrate species through predation, competition for resources (food & space), contamination (for pathogens and diseases), or hybridization (through reproduction) (Molnar et al. 2008; Bishop et al. 2010). Some individuals of non-native, invasive or other problematic species could be genetically modified (for instance by introducing Trojan sex chromosomes) and introduced to the population to reduce their environmental tolerance, fitness or reproductive capacity (Allendorf & Lundquist 2003; Cotton & Wedekind 2007). This can potentially reduce their ability to hybridize with native species, but also reduce their population over time and with it the threats they pose to native species.
