A thermophilic hormone-sensitive lipase family esterase Est1404 identified from an Antarctic bacterium Pseudomonas sp. E2-15

Polar Research
Esterases are a group of enzymes with a diverse range of uses in industry. We identified a novel hormone-sensitive lipase (HSL) in the esterase family, Est1404, through cloning and expression from the Antarctic bacterium Pseudomonas sp.

Becoming climate sentinels

American Ethnologist, EarlyView.
Abstract In South Korea, forest scientists refashion themselves as “climate sentinels” as they confront subtle yet disquieting shifts in plant seasonality brought about by climate change. Unlike traditional sentinels, who watch for external threats from a frontier, climate sentinels face ecological anomalies and surprises—such as untimely flowering ...

Histomorphology Structure of the Gastric Caecum, Midgut, and Malpighian Tubules in Adult Flatheaded Pine Borer Chalcophora mariana (Linnaeus, 1758) (Coleoptera: Buprestidae)

Acta Zoologica, EarlyView.
ABSTRACT The pine weevil is one of the largest species in the jewel beetle (Buprestidae) family found in Central Europe and Turkey. Chalcophora mariana is generally considered a secondary guest and primarily develops in weakened, decaying, or recently dead pine trees.

Lead isotope evidence for Antarctic Ice Sheet changes in the Weddell Sea sector since the Last Glacial Maximum

Boreas, EarlyView.
The Weddell Sea influences global ocean circulation and sea level through modulating Antarctic Bottom Water formation and Antarctic Ice Sheet discharges, but the history of ice‐sheet dynamics in this region remains poorly constrained due to limited well‐dated geological records.

Authoring Terrestrial Planets with Diffusion Models

Computer Graphics Forum, EarlyView.
Abstract To support the design and subsequent generation of terrestrial planets for use in the creative media, we propose a solution that employs a generative model trained on satellite data from planetary bodies with a defined solid surface, such as the Earth and Mars.

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 ...
