A new study from researchers at Macquarie University, Ursinus College, and the New England Aquarium has uncovered even fewer North Atlantic right whales are capable of reproducing, a significant finding as the species continues to face threats from human activities including fishing gear entanglements and vessel strikes.

Biological invasions are impacting biodiversity, ecosystem, and socio-economics globally. Marine non-indigenous species (mNIS) can be introduced through human activities, such as maritime shipping and careless discarding of aquarium species. Despite significant efforts to prevent the introduction of mNIS, occurrences continue to arise, including fishes, crustaceans, ascidians, anthozoans, bryozoans, sponges, macroalgae, seagrasses and mangroves (Alidoost Salimi et al., 2021). Once mNIS establish in recipient regions, controlling and eradicating them becomes a challenging task. Early awareness of mNIS could enhance the effectiveness of early response, particularly during the introduction phase, which is critical to reduce the impacts of mNIS in the future. Therefore, it is imperative to develop reliable and cost-effective strategies for the early detection of mNIS before they successfully establish themselves in new habitats and pose threats to local biodiversity.
