Neural Networks and Multivariate Analysis Based on Geochemical Data to Determine Stone Provenance From Ancient Calabrian Quarries (Southern Italy)

Archaeometry, EarlyView.
ABSTRACT This study shows an innovative approach to determine the origin of some Calabrian rocks quarried used in ancient times. Twenty‐five quarries, distributed in all the Calabrian provinces (Southern Italy), were studied and sampled. Ten samples were taken from each quarry, for a total of 250 samples.

The last glacial cycle in western Norway—extensive MIS 5d glaciation, multiple glacial advances and LGM glacial advance phases

Boreas, EarlyView.
Raised marine MIS 5c sediments evidence extensive preceding (5d) glaciation in western Norway. This is the first out of five (or six) major Weichselian glacier advances that seem to correspond to North Atlantic sea surface cooling periods. Till beds capping the marine sediments show stages of pre‐LGM advance and subsequent retreat.

A revised classification system of the marronoid clade of spiders (Araneae), based on dense sampling phylogenomics and comparative morphology

Cladistics, EarlyView.
Abstract The marronoid clade is a globally distributed, ecologically diverse group of spiders. It is an important faunal component in both natural and synanthropic environments, and even found in aquatic and extreme habitats such as desert salt flats. The systematics of the marronoid clade has been notoriously unstable due to the widespread character ...

The collective application of shorebird tracking data to conservation

Conservation Biology, EarlyView.
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Twelve principles for successful governance of community‐based coastal marine restoration

Conservation Biology, EarlyView.
Abstract Global agreements, such as the Global Biodiversity Framework, call for urgent, large‐scale action to halt biodiversity loss through a whole‐of‐society approach. Community‐based restoration can play a crucial role in achieving this goal, yet there remains limited understanding of what makes these projects effective and sustainable.

Bioethics and the World Order: A Curious Coincidence Between Chinese and African Approaches

Developing World Bioethics, EarlyView.
ABSTRACT The post‐1945 world order is standardly pictured as a Westphalian system, in which each state is equal under the law with sovereign authority over its territories. This paper argues that the Westphalian system is changing and examines the implications for bioethics. We show that cross‐border health, economic, ecologic, and sociopolitical risks

High Strength Steel Fatigue Crack Growth Database for Offshore Renewable Energy Applications

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT High strength steels can reduce costs and carbon emissions in offshore renewable energy, but their effect on structural integrity remains unclear. In welded structures, such as support structures for offshore wind and tidal turbines, fatigue life is dominated by crack growth from flaws at weld toes.
