Late Holocene Evolution of the Lagoonal Harbour of the Punic Centre of Othoca (Western Sardinia, Mediterranean Sea)

Geoarchaeology, Volume 40, Issue 2, March/April 2025.
ABSTRACT Geophysical surveys and multiproxy analyses of sediment cores have been used to reconstruct the palaeoenvironmental evolution of the Santa Giusta coastal lagoon (SGL), along the western coast of Sardinia. This area served as a natural harbour mainly during the Punic and Roman Republican periods (6th–2nd century bc).

Chemical Profiling Provides Insights into the Metabolic Machinery of Hydrocarbon-Degrading Deep-Sea Microbes

mSystems, 2020
Marine microbes are known to degrade hydrocarbons; however, microbes inhabiting deep-sea sediments remain largely unexplored. Previous studies into the classical pathways of marine microbial metabolism reveal diverse chemistries; however, metabolic ...

Evolution of the vaquita/totoaba socio‐ecological system in the Upper Gulf of California, Mexico

Ecosphere, Volume 16, Issue 2, February 2025.
Abstract The Upper Gulf of California (UGC) hosts a rich marine biodiversity. Complex climatic processes generate high biological productivity enabling the use of resources in a complex socio‐ecological processes (SEPs). Through a literature review, evolution and aggravation of the SEP over 50 years are analyzed.

Explosive Ocean Island Volcanism Explained by High Magmatic Water Content Determined Through Nominally Anhydrous Minerals

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 2, February 2025.
Abstract Ocean island basalt (OIB) magmas are generally water poor and usually contain less than 1 wt.% of H2O. Explosive eruption styles are therefore rare. When explosive eruptions occur, they are thought to be driven by either volatile‐enriched mantle sources or by gas segregation processes during magma differentiation.

Movement Ecology of a Coastal Foundation Seagrass Species: Insights From Genetic Data and Oceanographic Modelling

Diversity and Distributions, Volume 31, Issue 2, February 2025.
ABSTRACT Aim Seed dispersal plays a key role in shaping the distribution and genetic complexity of seagrass populations and affects their resilience capacity under disturbance. The endemic seagrass Posidonia oceanica is a key component of Mediterranean coastal ecosystems, but knowledge about movement ecology in this species is limited, especially ...
