Effects of restoration practices on biodiversity in temperate and boreal forests
Conservation Biology, EarlyView.Abstract Several restoration practices are used to mitigate and compensate for the negative effects of large‐scale forestry on biodiversity in temperate and boreal forests. A comprehensive synthesis of the benefits of these practices across taxa is missing. We conducted a systematic review and meta‐analysis on this topic.

Intact coastal nursery rearing amid climate‐driven phenological shifts in threatened salmon
Conservation Biology, EarlyView.Abstract Literature linking phenology to climate has proliferated in recent decades and shows that climate change has reorganized seasonal opportunities worldwide. However, this literature often quantifies changes in point measures of timing (e.g., beginnings and peaks) without context about duration (e.g., rearing season length) or performance (e.g ...

Subspecies taxonomy reflects social and geographic patterns of taxonomic effort in tetrapods
Conservation Biology, EarlyView.Abstract Subspecies have been used in conservation biology to account for intraspecific patterns in genetic diversity, which is crucial to long‐term population viability. Although over 3200 subspecies are currently assessed by the International Union for Conservation of Nature Red List, their biological relevance remains controversial.

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Lignin hydrogenolysis is a promising route to separable aromatic monomers, yet practical upgrading is still hindered by macromolecular mass‐transfer limitations and the aggregation/deactivation of metal sites. Herein, we propose a “dual‐confinement” strategy to construct ultrafine Ru nanoclusters supported on lignin‐based N‐doped hierarchical ...

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT In MAX‐phase‐derived metal–matrix composites, the M‐site element simultaneously governs carbide chemistry and matrix precipitate stability, yet it has traditionally been selected empirically rather than from a predictive criterion linking M‐site choice to carbide chemistry, matrix alloying, and L12 stability; moreover, the reaction pathway ...

Time‐Efficient Columnar‐to‐Equiaxed Transition via High Magnetic Field Processing
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT The need to simplify processing routes and improve processing efficiency motivates the development of time‐efficient methods for inducing the columnar‐to‐equiaxed transition (CET) during solidification while tailoring material performance. Conventional multistep CET approaches are time‐consuming and often struggle to simultaneously regulate ...
