The hyperiid amphipod Brachyscelus rapacoides is a warm-water species associated with gelatinous zooplankton. In the Mediterranean it has been reported in association with Rhopilema nomadica in both Israel and Turkey. Here, we document the first record of B. rapacoides in Greek waters, representing the first confirmed record for Europe, based on both morphological examination and DNA barcoding of the mitochondrial COI gene. Sp...

Climate change and ocean acidification pose significant challenges to both terrestrial and aquatic ecosystems, making it critical to understand species’ vulnerability. Phenotypic plasticity and evolutionary adaptation are key mechanisms enabling organisms to cope with environmental shifts, with marine species appearing particularly susceptible. This semi-quantitative bibliometric review, conducted following PRISMA guidelines,...

Research on the human health risks of climate change is expanding, yet the influence of polar region shifts on these risks remains underexplored. This paper presents a framework to assess global and regional health risks stemming from polar physical changes. The polar regions are experiencing rapid environmental transformations, including melting ice, ocean warming, ocean acidification, permafrost thaw, intensifying wildfires,...

Coastal coral reef ecosystems are experiencing increased environmental stress due to anthropogenic activity. Migration through larval dispersal is one of the mechanisms by which coral may be able to persist under such pressures. However, the genetic diversity and connectivity among coral populations from remote areas, such as Mozambique reefs, are not fully resolved. Patterns of water currents and eddies within the Mozambique...

Ocean acidification, a direct consequence of anthropogenic carbon dioxide emissions, is among the major challenges for marine organisms. While an increased body of evidence is documenting the negative effects of ocean acidification, most of these studies are still based on short‐term exposure. Long‐term experiments, studying multiple traits simultaneously, and accounting for short‐term local pH variability in the species' habi...

For more than 60 years, the International Atomic Energy Agency (IAEA) has promoted the peaceful use of nuclear science and technology for addressing major socioeconomic and sustainable development priorities at national, regional, and interregional levels. The Agency’s Technical Cooperation (TC) Programme is the primary mechanism for transferring nuclear and related technologies to its Member States, helping them to address th...

Addressing global challenges such as climate change requires large-scale collective actions, but such actions are hindered by the complexity and scale of the problem and the uncertainty in the long-term benefit of short-term actions (Jagers et al., 2019). In addition to climate change, socio-ecological systems face the cumulative pressures associated with resource needs, technology development, industrial expansion, and area c...

Ocean acidification (OA) is broadly recognized as a major problem for marine ecosystems worldwide, with follow-on effects to the economies of ocean-dependent communities. The urgent need to mitigate and minimize the impacts of OA is a scientific and political priority, as highlighted by the latest Intergovernmental Panel on Climate Change report (IPCC, 2022) and by the inclusion of OA as a target in the United Nations Sustaina...

Ocean acidification (OA), an alteration of seawater chemistry caused primarily by anthropogenic carbon emissions, is a global issue. However, the local expression of OA can vary widely in nearshore waters around the world. This is due to localized factors such as river input, eutrophication, topography, location (e.g., temperature), and sensitivity of local species. Human impacts from OA also vary depending on societal uses of...

Bivalve farming was usually considered as a CO 2 source through respiration and calcification, but recent studies suggest its potential as a CO 2 sink, prompting exploration of its inclusion in carbon markets. Here we reviewed the scientific basis behind this idea and found that it is not supported by observational and experimental studies. This idea indeed arises from carbon budget models that are based on theoretical misconc...

Bioluminescence, the ability of organisms to produce visible light, has intrigued scientists for centuries. Studies have examined bioluminescence, using a wide range of approaches and organisms, from its ecological role to its underlying molecular mechanisms, leading to various applications and even a Nobel prize. Over the last ten years, an increasing amount of data has been collected leading to a growing number of recognized...
