Relationships between spatiotemporal distribution of salt spray deposition and growth status of coastal greening plants—a case study at Gulei Peninsula, Fujian [PDF]
, 2017 滨海地区具有海、陆属性动态而复杂的自然环境，这赋予滨海绿化以特殊性，需同时考虑海洋环境和大陆环境对植物的影响，而滨海绿化面临的主要难题正是来自空气和土壤中的盐分对植物造成的伤害。目前国内外有关盐雾的研究集中于植物受盐雾胁迫的生理机制、耐盐雾植物资源的筛选等，而研究盐雾时空分布特征，并结合绿化工程案例探讨绿化植物的受盐雾危害情况和预防盐雾措施的较少。 本文以植物遭受盐雾危害严重的福建省古雷半岛为例，于2016年5月～2017年3月分春、夏、秋、冬四个季节对盐雾沉降、环境因子和绿化植物长势进行跟踪调查 ...

Conservation Biology, Volume 40, Issue 2, April 2026.Scaling area‐based conservation, including initiatives led or comanaged by Indigenous Peoples and local communities, is a flagship goal of the Kunming‐Montreal Global Biodiversity Framework. Conservationists often aspire to scale initiatives, but this is rarely achieved in practice. Identifying and addressing factors that limit initiative adoption (i.e.

野生动物学报, 2012 南非海狮是目前国内外动物园、水族馆中饲养比较普遍的动物,但经常出现一些细菌性、病毒性和寄生虫等疾病,在海狮健康状况监测和疾病诊断中需要有生理生化指标正常值作为参考。但目前南非海狮的正常生理生化指标报道较少。杭州动物园先后对6只成年南非海狮进行采血,共收集20个（12雄8雌）血液常规样本测定了15项主要生理指标和6个（4雄2雌）血清生化标本对18项主要生化指标进行检测。在测定项目中WBC、RBC、MCH、MCV、RDW、HCT、MPV、PCT、ALT、TP、ALB、TBIL、GLU、Ca2+、Pi、Mg2+

Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.

Strengthening community‐based fisheries monitoring programs with Indigenous perspectives
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Community‐based monitoring (CBM) programs are increasingly recognized as essential for adaptive environmental stewardship. Yet, the CBM literature often highlights successful cases and privileges evaluations by external experts over those of community members themselves.

Shuitu Baochi Xuebao, 2007 土壤干层是黄土高原普遍存在的特殊土壤水文现象,研究其现状、成因、防治、调控措施等对科学认识区域植被承载力、土地生产力以及低效林草改造和可持续植被建设等有重要理论与生产指导意义,而合理通用评判指标与分级标准是开展土壤干层研究的基础。目前黄土高原土壤干层尚无统一评判指标与分级标准,给区域土壤干层研究带来困难。本文在已有研究成果的基础上,提出用土壤有效水饱和度/不饱和度作为土壤干层评判指标,并给出其分级标准。该评判指标计算简单,具通用性和可比性,可望成为土壤干层的通用评判指标。

Seedling Growth and the Environmental Factors of the Non-native Mangrove Species, Sonneratia caseolaris, in Shenzhen Bay [PDF]
, 2017 选取深圳湾红树林的林缘、林窗及郁闭海桑Sonneratia caseolaris林和秋茄Kandelia obovata林等4种环境下自然生长的海桑幼苗，测其生物量、光合特性等指标。结果表明，林缘海桑幼苗生物量累积最大，叶片生物量所占比重最高，幼苗通过提高叶片面积和叶片数量，增加光合速率、水分利用率和光合氮利用率而加速生长。综合分析4种环境的环境因子发现，光照强度是决定幼苗速生并占领生态位的关键生态因子。该结果为研究深圳湾外来种海桑的危害及其防控和管理措施提供参考。This study aimed to

How much biotic nativeness matters across human demographic groups
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Many central concepts of conservation biology—such as nativeness—are structured by ecological and social factors. However, the social consequences of using these concepts to make conservation decisions remain inadequately understood. Some researchers argue that nativeness, rather than acting as an objective proxy for important ecological ...

Shuitu Baochi Xuebao, 2005 铝毒害是限制酸性土壤中植物生长的重要因素,以荞麦(FagopyrumesculentumMoench.)为实验材料,在沙培条件下,用不同浓度(0,10,100,1000mg/L)、不同pH(3,4,5)的铝溶液处理,在出苗后的第14d和28d测试与铝胁迫有直接关系的5个生理指标。结果表明,溶液的铝浓度和pH的变化对荞麦生理都有明显的影响,最低浓度的铝处理10mg/L在不同pH下已经影响了荞麦的正常生长,和对照相比根系活力(RA)下降、根质膜透性(MP)增大、叶片内丙二醛(MDA)和游离脯氨酸(Pro ...
