Simulating Ocean Alkalinity Enhancement along the European Coast in an Earth System Model

, 2023
To assess the potential of coastal ocean alkalinity enhancement as a CO2 removal option for climate change mitigation, the Flexible Ocean and Climate Infrastructure (FOCI) earth system model was used to simulate alkalinity addition at the European coast ...

Assessment of Oxidative Stress, Vitellogenin, and Human Health Risks Derived From Nile Tilapia Exposed to Metals and Metalloids in Southeastern Brazil

Environmental Toxicology, EarlyView.
ABSTRACT Urban coastal lagoons are highly vulnerable ecosystems increasingly affected by metal contamination, as well as multiple anthropogenic stressors. This study evaluated ecotoxicological and human health risks associated with chronic metal exposure in Nile tilapia (Oreochromis niloticus) from an anthropogenically impacted lagoon in southeastern ...

Ocean Alkalinity Enhancement: Tool to Mitigate Climate Change

In the face of climate change challenges, characterized by rising atmospheric carbon dioxide (CO2) concentrations and the consequential threats of approaching climate tipping points, including sea level rise, more wildfires, and escalating heatwaves, there exists a pressing need to explore effective strategies to mitigate these CO2-related issues.

KOSMOS 2021 Gran Canaria mesocosm study on ocean alkalinity enhancement: phytoplankton metabolic rates

Ocean Alkalinity Enhancement (OAE) could augment long-term carbon storage and mitigate ocean acidification by increasing the bicarbonate ion concentration in ocean water. However, the side effects and/or potential co-benefits of OAE on natural planktonic

Ocean acidification, more than warming or heatwaves, constrains shoaling behaviour in a range‐extending fish through habitat simplification

Journal of Animal Ecology, EarlyView.
We show that ocean acidification, more than warming or marine heatwaves, alters shoaling behaviour indirectly by simplifying reef habitat and reducing population densities and shoal sizes. Because fish behaviour can be strongly mediated by shoal size, climate‐driven habitat change may reshape social dynamics that influence how range‐extending fishes ...

Hox Gene Variation Drives Morphological Specialization of Humpback Grouper Cromileptes altivelis

Integrative Zoology, EarlyView.
Cromileptes altivelis exhibits a distinctive “sunken head and humpback” morphology, formed through cranial remodeling. Genetic analyses identified unique amino acid variants in Hoxa7a and Hoxa10b, with functional tests confirming their role in enhancing osteoblast activity and driving cranial remodeling.

Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

Archaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

Using Variable Chlorophyll-a Fluorescence to Assess the Impact of Ocean Alkalinity Enhancement on the Photochemical Efficiency of Phytoplankton

Ocean Alkalinity Enhancement (OAE) is a potential carbon dioxide removal strategy to mitigate climate change by enhancing oceanic carbon uptake. This thesis contributes to the biological risk assessment of OAE by examining its effects on phytoplankton ...
