Conservation Biology, EarlyView.Abstract Modeling species distributions in dynamic pelagic environments remains challenging, particularly for wide‐ranging and highly mobile species when there is limited guidance on model performance. This limitation constrains the effective use of species distribution models (SDMs) in marine conservation, where robust and transferable predictions are

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.

Methodology to identify ecologically matching areas and its applications in conservation planning
Conservation Biology, EarlyView.Abstract Identifying ecologically matching areas is both challenging and critical for understanding spatial patterns of biodiversity and advancing conservation planning. However, existing approaches often lack spatial flexibility, overlook shape and size constraints, or rely on limited environmental parameters, reducing their effectiveness in real ...

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT A thermomechanical strategy based on rolling‐annealing cyclic (RAC) was developed to regulate defect architecture and precipitation behavior in a (FeCoCrNi)94Al3Ti3 high‐entropy alloy. Intermediate annealing during rolling enables progressive grain refinement and introduces a high density of twins, stacking faults, and dislocations, forming a ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT The deformation behavior of NiTiNb shape memory alloys is governed by microstructural heterogeneity, specifically the interconnected topology of the β‐Nb phase. The regulatory role of the eutectic structure in load partitioning and the evolution of deformation mechanisms, particularly in high‐Nb systems, has not been clearly understood.

Integrative Conservation, Volume 5, Issue 3, Page 255-267, September 2026.This study presents a comprehensive review of the 500‐year spatiotemporal evolution of global botanical gardens, identifying three major development stages—initial exploration (1543–1699), steady expansion (1700–1899), and rapid proliferation (1900–2020)—with six distinct sub‐stages. We propose a tripartite driving framework grounded in colonial botany

Integrative Conservation, Volume 5, Issue 3, Page 281-292, September 2026.We comprehensively evaluated the seed plant diversity of Jiangxi province to address the regional biodiversity conservation of Asian subtropical evergreen broad‐leaved forests (EBLFs). Higher species diversity of seed plants was observed in eastern, southern, and western Jiangxi, with elevation and precipitation as mainly environmental factors.

Canine Distemper Virus Research in China and Future Directions for Conservation 中国犬瘟热病毒研究现状与保护策略展望
Integrative Conservation, Volume 5, Issue 3, Page 268-280, September 2026.ABSTRACT Canine distemper is a highly contagious, severe disease caused by the canine distemper virus (CDV). With a worldwide distribution and ever‐expanding list of susceptible hosts, CDV poses a growing risk for many threatened wildlife species, both in captivity and their native habitats. As a megadiverse country, China is home to myriad endemic and
