Editorial: The threat of invasive alien species and the challenge of climate change
## Editorial: The Threat of Invasive Alien Species and the Challenge of Climate Change The escalating impacts of climate change are not occurring in isolation; they are synergistically amplifying the threat posed by invasive alien species. Altered ocean temperatures, shifting currents, and increased storm frequency create unprecedented opportunities for non-native organisms to establish and proliferate, disrupting fragile marine ecosystems. Addressing this complex interplay demands integrated data and rigorous analysis.
Correction: Climate-driven phenological shifts and biogeographical constraints of the hydrozoan Velella velella in Mediterranean coastal waters
Recent research validates significant shifts in the distribution and lifecycle timing (phenology) of *Velella velella*, a hydrozoan species, within Mediterranean coastal waters, demonstrably linked to climate change. Empirical data reveal biogeographical constraints impacting this species’ range, highlighting the cascading effects of altered ocean conditions. This study contributes critical ocean intelligence regarding climate indicators and ecosystem response. For further insights into deep-sea exploration informing our understanding of ocean dynamics, see "Camera 1: 2026 Cook Islands ROV Exploration (EX26045)."
Disentangling the structure of an Antarctic plankton food web in bloom and non-bloom conditions
Understanding Antarctic marine ecosystems requires a clearer picture of plankton food web dynamics. This study, utilizing a network-based approach, disentangles these trophic relationships in Potter Cove under both phytoplankton bloom and non-bloom conditions, drawing on a 30-year longitudinal dataset. Findings reveal increased food availability for higher trophic levels during blooms, while microzooplankton play a crucial role in energy transfer during non-bloom periods.
