Invasions of non-native species into ecosystems can have important ecological and economic consequences. Some estimates suggest that invasive species are the second greatest threat to biological diversity worldwide and cost economies billions of dollars through resource losses and control programs. Relationships between biodiversity and biological invasions are typically considered from two perspectives. One perspective focuses on how biological invaders impact biodiversity of native ecosystems by competing with or preying on native species. Non-native species introduced to ecosystems may interact with native resident species that are "naïve," and thus vulnerable, to novel invasive predators, pests, pathogens, habitat transformers, or competitors. The other perspective focuses on how biodiversity of resident communities may impede biological invaders because ecosystems with greater numbers of species may resist colonization by non-native species. Clearly important reciprocal relationships, and potential feedbacks, between biological diversity and biological invasions of ecosystems exist. This issue will broadly focus on relationships between biological diversity and biological invasions including testing conceptual theories and the application of theories from various ecosystems.
