Shuitu Baochi Xuebao, 2021 植被覆盖度变化及其与驱动因子关系的研究是开展大规模植被恢复效益评估的基础，而目前对西南槽谷地区植被绿化的时空变化模式及其驱动因素的认识并不明晰，不利于进一步生态建设。基于2000—2018年西南槽谷区NDVI、气温、降雨、DEM、土地覆被和人口密度数据，应用线性趋势回归分析和Hurst指数分析等方法以及地理探测器模型，探究了西南槽谷区植被覆盖的时空变化特征和驱动因素，预测未来变化趋势。结果表明：（1）近19年来NDVI范围介于0.79~0.84，总体呈波动上升趋势，岩溶区植被NDVI （0.003 17/

Jellyfish blooms restructure plankton dynamics and trophic linkages in coastal waters
Functional Ecology, Volume 40, Issue 5, Page 1443-1460, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Jellyfish blooms are increasing globally in frequency and intensity, introducing complex ecological interactions, yet the mechanisms by which they alter ecosystem structure remain poorly characterized due to a lack of sustained field observations.

Shuitu Baochi Xuebao, 2017 通过室内水槽模拟冲刷试验，研究缓坡坡降1.4%、流量0.6～1.8 L/s、非淹没条件下，植被类型（柔性植被、刚性植被）和植被配置格局（棋盘状格局、长条状格局、带状格局）对坡面流水深、流速、流态、达西阻力系数等水动力学特性的影响，探究其规律。结果表明：（1）与裸坡相比，植被具有雍水缓流作用，水深雍高1.4～2.8倍，流速延缓31%～65%，植被格局较植被类型作用更为明显，其中柔性植被、带状格局雍水效果最好。（2）坡面流态指数m显示刚性植被、棋盘状格局条件下水流紊动性最强，而坡面综合指数k显示刚性植被 ...

Striking a balance: Stakeholder perceptions of risk in horse racing
Equine Veterinary Journal, Volume 58, Issue 3, Page 814-823, May 2026.Abstract Background Thoroughbred racing is a major industry, and in recent years public concerns about equine safety have become more prominent, particularly in relation to on‐track injuries and fatalities. This has challenged the industry's social licence to operate (SLO).

AGP and EXO‐LIKE genes promote brassinosteroid‐dependent anisotropic growth
New Phytologist, Volume 250, Issue 4, Page 2384-2398, May 2026.Summary The brassinosteroid pathway promotes anisotropic cell expansion; however, the effectors in this process remain unclear. Candidates include ARABINOGALACTAN PROTEIN (AGP) genes, which are prominent brassinosteroid‐responsive transcriptional targets, and EXORDIUM (EXO)‐LIKE (EXL) genes.

Field Study on Effects of Simulated Sea Level Rise on Main Processes of Organic Carbon in Kandelia obovata Mangrove Ecosystems [PDF]
, 2015 本研究以厦门曾营海岸三个不同高程样地的秋茄红树林为研究对象，在模拟海平面上升80cm红树林（SLR80cm）、模拟海平面上升40cm红树林（SLR40cm）以及对照红树林（SLR0cm，大约相当于福建九龙江口红树林的滩面高程），探讨海平面上升对秋茄（Kandeliaobovata，以前学名为Kandeliacandel）红树林生态系统主要有机碳过程的影响。 SLR80cm样地的植株矮小、林相稀疏，生长状况明显不如SLR40cm和SLR0cm样地。各样地植株的生物量以及年增量总体均呈现出SLR0cm ...

Conservation Biology, Volume 40, Issue 2, April 2026.Abstract The Natura 2000 (N2K) network of protected areas is one of the main tools for area‐based conservation in the European Union (EU), yet its role in preserving plant biodiversity requires better understanding. We examined data kept in the European Vegetation Archive from over 1.2 million vegetation plots and obtained over 14.2 million plant ...

牛山湖两种不同生境小型鱼类的种类组成、多样性和密度 [PDF]
, 2007 研究了2003年春季浅水草型湖泊牛山湖小型鱼类空间分布(种类组成、多样性和密度等)与生境异质性之间的关系.根据水生植被状况、离岸距离和水深,选择了两种差异较大且有代表性的生境类型,即近岸沉水植物茂密的生境A和远岸沉水植物稀疏的生境B.使用围网(180m2)在这两种生境中进行小型鱼类的采样,采用多次标志回捕法和Zippin去除法估算了围网内小型鱼类的密度.结果表明,两种不同生境中小型鱼类的种类组成、多样性度量值和密度估算值均存在一定程度的差异:1)生境A中的渔获物由5科14种小型鱼类组成 ...
