Study on the effect of Mytilopsis sallei on ecological environment in Yundang Lagoon, Xiamen [PDF]
, 2009 外来物种沙筛贝（Mytilopsissallei）原产于中美洲热带水域，随着航运的发展入侵世界上许多国家和地区，对入侵地造成巨大的经济损失。筼筜湖位于厦门岛西南部，旧称筼筜港，原是一片天然的港湾。20世纪70年代初，为围海造田，修建了西堤，使筼筜港变成一座基本封闭的人工泻湖，水体污染较为严重，水交换能力大大减弱，改称筼筜湖。筼筜湖水体呈富营养化状态，湖内属重污染水体。海洋入侵种是生态变化的主要驱动者，它们适应当地栖息环境，与本地种竞争，还可能是带菌者，对生物多样性造成严重的危害。因此 ...

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.
New Phytologist, Volume 250, Issue 2, Page 1231-1247, April 2026.Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

2011年夏季渤海西北部、北部近岸海域的底层耗氧与酸化 [PDF]
, 2012 于2011年6月下旬和8月下旬调查了渤海中央海区.6月份渤海所有测站底层溶解氧都超过7.0Mg/l,饱和度为85%~115%,PH为7.82~8.04.而到了8月份,在渤海西北部、北部近岸水深20~35M的带状区域内出现底层溶氧显著下降并且酸化的现象.溶解氧最低值为渤海北部近岸的3.3~3.6Mg/l,只有6月份的44%~47%;相应PH为7.64~7.68,比6月份低0.16~0.20.表观耗氧速率最高和PH降幅最大的测站都出现在渤海西北部近岸海域,累积溶解氧下降5.6Mg/l,PH降幅则高达0.29,

Growing Demand and Uneven Supply: Eight Years of Nature Education in China 需求增长与供给不均:中国自然教育八年发展回顾
Integrative Conservation, Volume 5, Issue 1, Page 46-58, March 2026.ABSTRACT This study examines the role of nature education in advancing conservation and sustainability in China between 2014 and 2023. Drawing on national survey reports and historical–comparative methods, it analyses the dynamics of public demand, institutional supply, and practitioner capacity.

Research on Groundwater Discharge into Jiulongjiang Estuary [PDF]
, 2009 本论文依托国家自然科学基金项目“近岸海域的海底地下水排泄及其海洋生态环境效应研究（40672166）”，通过运用天然存在的镭同位素（224Ra，226Ra）示踪技术，对九龙江河口区的地下水输入通量进行评价，并对其输送的营养盐数量进行评估。 相对只有河水端元和海水端元保守混合的水体而言，九龙江河口区水体显然存在Ra的过量，推测有经由其它途径输入的Ra。通过识别九龙江河口区224Ra和226Ra的源汇项，认为它们的源项主要有：SGD输入的镭，河流输入的镭，河流悬浮颗粒解吸的镭，沉积物扩散的镭 ...

Integrative Conservation, Volume 5, Issue 1, Page 86-103, March 2026.Urbanization may alter bird foraging. Austral Parakeets (Enicognathus ferrugineus) in Patagonia rely on introduced plants in urban areas, especially in winter, despite preferring natives in the wild. This seasonal reliance on introduced species highlights urbanization trade‐offs and underscores the need to manage green areas with native plants to ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Single‐atom catalysis hinges on fundamental challenges in precisely controlling metal‐support interactions and rationally regulating metal–adsorbate relationships. Herein, we report a universal strategy for constructing highly efficient and well‐defined Cu(I) single‐atom catalysts based on a trifurcate AlL3 molecular support.

Shuitu Baochi Xuebao, 2006 生态位适宜度是对经典生态位理论和方法的深化与发展，在合理优化利用环境资源，发挥作物、环境最大共生效应，及工农业布局和指导农业生产中具有重要的实际意义。在可持续发展理论的指导下，以江汉平原后湖地区耕地为研究对象，将生态位适宜度模型引入到多宜性评价研究中，采用加权平均和限制因子模型对各评价单元水稻、油菜、小麦和棉花4种作物的生态位适宜度进行了定量分析。结果表明：研究区生态位适宜度值整体较高，生境条件基本能满足作物的需求；部分地块的生境条件需要改善；限制该地区土地生产潜力的生态因子主要为：CEC，速效磷和全氮。

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT High‐entropy alloys (HEAs) have attracted considerable interest from researchers owing to their tunable chemical compositions, exceptional structural stability, and promising catalytic properties. However, their large‐scale application is often hindered by complex manufacturing techniques and poor durability.

南方滨海地区盐雾沉降的时空分布——以福建古雷半岛为例 [PDF]
, 2019 研究滨海地区盐雾沉降的时空分布及其影响因素,以期为滨海绿化植物的选择与配置提供依据。以福建省古雷半岛为研究站点,设置盐雾沉降缸研究离海岸线距离和防护林对盐雾沉降量的影响;同时模拟不同生活型植物的高度,研究不同高度盐雾沉降量的差异。结果表明:春夏秋冬四季,盐雾沉降量均表现出随离海距离的增加逐渐降低的趋势,冬季盐雾沉降量在离海岸线500 m内快速下降,在500 m以外则下降速度趋缓;防护林的存在能减少盐雾沉降量,这种效果在盐雾危害严重的冬季更明显,可使盐雾沉降量降低15.4%;在无防护林遮挡条件下 ...
