Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

Biological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Peroxodisulfate‐Enhanced Leaching of Deep‐Sea Manganese Crusts and Sulfides

Chemie Ingenieur Technik, EarlyView.
Ammonium peroxodisulfate enables efficient leaching of deep‐sea manganese crusts and massive sulfides while offering electrolytic recycling. High leaching yields for V, Mn, Co, Mo, Sn, and W, along with complete leaching of As and Sb, highlight its potential as a powerful and sustainable oxidant for marine resource processing.

Improvement of Seagrass Habitat Mapping Using Integration of Habitat Suitability Model and Seafloor Classification Map

Asian Fisheries Science
Acoustic datasets offer considerable advantages in high-resolution seagrass habitat mapping applications. However, the nature of seafloor features for seagrass habitat on a habitat suitability model (HSM) is limited due to single–species output ...

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Embryonic development of the Mediterranean starfish Hacelia attenuata

Developmental Dynamics, EarlyView.
Abstract Background Starfish play essential ecological roles as predators and ecosystem regulators; however, detailed developmental descriptions exist for only a handful of species, none of which are from the Mediterranean Sea. Results In this study, we provide the first full account of the development of the Mediterranean starfish Hacelia attenuata ...

A Comparison of Screening Methods for Assessing Legacy Wells Within CO2 Storage Licences: Application to Offshore Norway

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Legacy wells represent a critical consideration for offshore CO2 storage projects, as they may provide potential pathways for fluid or gas migration if poorly constructed, undocumented or inadequately abandoned. Systematically assessing large numbers of legacy wells remains challenging due to heterogeneous data availability and the diversity ...

Refinement of the Quaternary seismic stratigraphy and analysis of buried glacial channels on the Labrador Shelf

Journal of Quaternary Science, EarlyView.
ABSTRACT The Laurentide Ice Sheet covered vast areas of North America during the Wisconsinan, including the Labrador Shelf, off the coast of eastern Canada. The shelf is characterized by glacial cross‐shelf troughs, which have been considered as predominantly eroded by the last ice advance.
