Invasive Fish and Sea Urchins Drive the Status of Canopy Forming Macroalgae in the Eastern Mediterranean

Biology, Год журнала: 2023, Номер 12(6), С. 763 - 763

Опубликована: Май 24, 2023

Canopy-forming macroalgae, such as Cystoseira sensu lato, increase the three-dimensional complexity and spatial heterogeneity of rocky reefs, enhancing biodiversity productivity in coastal areas. Extensive loss canopy algae has been recorded recent decades throughout Mediterranean Sea due to various anthropogenic pressures. In this study, we assessed biomass fish assemblages, sea urchin density, vertical distribution macroalgal communities Aegean Levantine Seas. The herbivore was significantly higher South compared North Aegean. Very low densities suggest local collapses Levantine. most sites Levantine, ecological status or very at depths deeper than 2 m, with limited no algae. many sites, were restricted a narrow, shallow zone, where grazing pressure may be harsh hydrodynamic conditions. Using Generalized Linear Mixed Models, demonstrated that presence is negatively correlated invasive Siganus spp. urchins. s.l. forests alarming, urgent conservation actions are needed.

Abstract Managing marine nonindigenous species (mNIS) is challenging, because environments are highly connected, allowing the dispersal of across large spatial scales, including geopolitical borders. Cross-border inconsistencies in biosecurity management can promote spread mNIS borders, and incursions often go unnoticed or unreported. Collaborative surveillance programs enhance early detection mNIS, when response may still be possible, foster capacity building around a common threat. Regional international databases curated for inform local monitoring real-time information exchange on concern. When combined, reference libraries, publicly available databases, predictive modeling facilitate development regions lacking baseline data. Biosecurity should practical, feasible, cost-effective, mainly focused prevention detection, built collaboration coordination government, nongovernment organizations, stakeholders, citizens rapid response.
