Global drivers of the conservation–invasion paradox

open access: yesConservation Biology, Volume 39, Issue 5, October 2025.
Abstract The conservation–invasion paradox (CIP) refers to a long‐term phenomenon wherein species threatened in their native range can sustain viable populations when introduced to other regions. Understanding the drivers of CIP is helpful for conserving threatened species and managing invasive species, which is unfortunately still lacking. We compiled

Riverine Nitrate Export Response to Hydro-climatic Variability in a Southeast China Coastal Watershed Based on Long-term Historical Data [PDF]

open access: yes, 2015
气候变化对不同的自然地理区域的淡水系统,尤其是人口集中、对水资源高度依赖的近海流域的潜在影响的研究对于制定合理的水资源管理策略至关重要。本篇论文选取中尺度近海流域—九龙江流域,基于1961-2013年近53年的水文-气候与硝酸盐水质数据,评估气候变化对流域水量和水质及通量的影响。研究结果表明,在过去的50年里,九龙江北溪和西溪年径流量没有明显变化趋势,但随年降雨变化,呈自然波动。本研究开发的L-R图解法显示土地变化加强了气候变化对径流动态的影响。上世纪60年代至90年代之间,硝酸盐的浓度增加了30倍 ...

Effects of Shifting Cultivation on the Western Hoolock Gibbon (Hoolock hoolock) in Western Myanmar 刀耕火种对缅甸西部西部白眉长臂猿 (Hoolock hoolock) 的影响摘要

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 503-513, September 2025.
Fire occurrence increased with proximity to roads and villages, indicating that human access and activity are major drivers of fire risk. We analyzed spatial patterns of fire in relation to human settlements. Our findings highlight the need for fire management strategies that consider accessibility and human presence in conservation planning.

Structural design of highly permeable Bi2O3 microspheres decorated by Pt‐nanoparticles: facile synthesis and acetic acid sensing performance

open access: yesRare Metals, Volume 44, Issue 9, Page 6417-6425, September 2025.
Graphic abstract Abstract Real‐time detection of acetic acid vapor is of concern for ensuring environmental and personal safety. However, acetic acid gas sensors, particularly those based on Bi2O3, often fail to meet practical performance requirements owing to their slow response characteristics and high operating temperature.
