The impact of urbanisation on social behaviour: a comprehensive review

Biological Reviews, EarlyView.
ABSTRACT Urbanisation is a key driver of global environmental change and presents animals with novel stressors and challenges. It can fundamentally influence social behaviour and has the potential to reshape within‐ and between‐species social interactions. Given the role of social behaviour in reproductive fitness and survival, understanding how social

Detection of the White Dwarf Spin of the Long-orbital Period Magnetic Cataclysmic Variable V1082 Sgr

The Astrophysical Journal
We report on the discovery of circular polarization modulated with a period of 1.943 ± 0.002 hr in the cataclysmic variable V1082 Sgr. These findings unambiguously reveal the rotation of a magnetic white dwarf and establish its intermediate polar nature.

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

Biological Reviews, EarlyView.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Asteroseismology of the ZZ Ceti and DAZ GD133

EPJ Web of Conferences, 2017
GD 133 is a DAZ white dwarf with an atmosphere polluted by heavy elements accreted from a debris disk, which is formed by the disruption of rocky planetesimals with orbits bringing them at the white dwarf tidal radius.

Nature at Risk, Finance at Stake: A Systematic Literature Review of Biodiversity Risk in Finance Research

Business Strategy and the Environment, EarlyView.
ABSTRACT Biodiversity‐related financial risk is increasingly recognized not only as a market concern but as an ethical and systemic imperative for businesses and financial institutions. This systematic literature review synthesizes 103 peer‐reviewed studies to examine how biodiversity risk is conceptualized, measured, and integrated within financial ...

Anti‐Inflammatory, Antioxidant, Molecular Docking and Pharmacokinetics Properties of Cycloeucalenone Isolated From Musa × paradisiaca L. Fruit Peels

Chemistry &Biodiversity, EarlyView.
ABSTRACT This study isolated a compound with anti‐inflammatory properties from Musa × paradisiaca fruit peels. The methanol extract was partitioned, and the hexane fraction with the best bioactivity was subjected to column chromatography before characterization via Fourier transform infrared (FTIR), UV–visible (UV–VIS) and NMR analysis.
