Non-native habitat as home for non-native species: comparison of communities associated with invasive tubeworm and native oyster reefs

[摘要] ABSTRACT: Introduction vectors for marine non-native species, such as oyster culture and boat fouling, often select for organisms dependent on hard substrates during some or all life stages. In soft-sediment estuaries, hard substrate is a limited resource, which can increase with the introduction of hard habitat-creating non-native species. Positive interactions between non-native, habitat-creating species and non-native species utilizing such habitats could be a mechanism for enhanced invasion success. Most previous studies on aquatic invasive habitat-creating species have demonstrated positive responses in associated communities, but few have directly addressed responses of other non-native species. We explored the association of native and non-native species with invasive habitat-creating species by comparing communities associated with non-native, reef-building tubeworms
