Root exudates mediate microorganisms to improve rhizosphere nutrient availability and crop productivity under straw mulching and slow‐release nitrogen fertilizer

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Root exudates play a key role as signals and nutrients in mediating plant–microbe communication. However, critical knowledge gaps remain regarding how root exudates mediate soil–microbe–plant interactions to regulate crop yield under long‐term straw mulching combined ...

A modeling study of hypoxia in the bottom layers off the Changjiang Estuary in summer [PDF]

open access: yes, 2016
近几十年来,受人类活动影响,大量有机污染物和营养物质经河流排放到长江口及其近岸海域,造成水体富营养化日益严重,致使长江口外近岸底层水体缺氧现象也呈不断上升趋势。长江口底层水体缺氧的形成是个复杂的过程,是物理过程和生化过程综合作用的结果。物理过程主要控制着溶解氧的水平和垂直输运,生化过程控制着溶解氧的产生和消耗。 近年来已有许多学者研究长江口水体缺氧现象,但目前针对该区域缺氧的研究主要局限于定性的观测分析。为了更好研究长江口水体缺氧的形成机制,本文应用一个三维水动力¬-生态耦合模式 ...

Emerging applications of large language models in ecology and conservation science

open access: yesConservation Biology, EarlyView.
Abstract Large language models (LLMs) mark a major development in artificial intelligence, with potentially transformative implications for ecology and conservation science. Built on advanced deep‐learning architectures, these models can support a wide range of tasks. We reviewed emerging applications of LLMs, drawing on the wider scientific literature

黄土高原清水河流域降水-径流的响应关系

open access: yesShuitu Baochi Xuebao, 2023
宁夏清水河流域地处黄土高原干旱、半干旱地区,选取清水河流域出口泉眼山水文站及气象站1989—2019年逐日径流和降水数据,并通过Chapman-Maxwell法对清水河流域径流时间序列进行基流分割,并将基流分割的结果应用于径流事件的分离,来探究径流事件对降水的响应特征。结果表明:(1)宁夏清水河流域降水量、径流量和基流量整体上均呈现上升趋势,经Mann—Kendall检验未发现突变显著的时间点,日降雨量10 mm以下的降水呈现增加趋势,年内降水主要分布在5—9月,占比达81.72%。(2 ...

Temporal and spatial variation of Zhe-Min Coastal Water in the Taiwan Strait in winter and spring [PDF]

open access: yes, 2016
台湾海峡是沟通东海与南海的唯一通道,也是我国南、北海运的重要航道。浙闽沿岸水是台湾海峡西侧主要流系,也是我国东南沿海环流系统的重要组成部分,它与海峡暖流水在季风控制下彼此消长,对海峡的环流结构、水团组成和海 洋生态等有着相当重要的影响。 本文主要利用1981年至2016年间不同时间段的AVHRR、MODIS遥感海表温度时序列数据,以温度阈值法和温度空间距平法为基础建立了台湾海峡浙闽沿岸水的表征方式,并分别定义其影响范围及强度指数。分析了自上个世纪八十年代以来冬、春季台湾海峡浙闽沿岸水的时空变动特征 ...

Laws, Enforcement, and Strategy: A Multi‐Layered Qualitative Study of Multinational Enterprise Compliance Under European Union and Chinese Data Protection Regimes

open access: yesPolicy &Internet, Volume 18, Issue 2, June 2026.
ABSTRACT In an era of proliferating but divergent data protection regimes, the European Union's rights‐based approach and China's sovereignty‐centric model have become two dominant poles of global data governance. This article examines how multinational enterprises navigate compliance under these dual systems and how that compliance is shaped through ...

Long-Term Trends of Macrobenthos in Southern Bohai Sea, China, in Relation toEnvironmental Changes [PDF]

open access: yes, 2016
根据50多年来渤海南部海域大型底栖动物群落的历史资料,以及2011~2013年的现场调查数据,从渤海南部包括黄河口邻近海域及莱州湾大型底栖动物群落结构变化特征出发,分析了其长期演变的过程和规律,旨在阐明底栖动物群落的演变趋势,识别其重要的演变时段.并结合50年来渤海南部海域相关底栖环境因子的变化特征,探讨底栖动物群落的演变原因.过去50余年来,渤海南部海域大型底栖动物群落在物种数、生物量、丰度以及群落结构组成等方面都发生了较大的变动,具体表现为寿命长、体积大、具有高竞争力的K对策种的优势地位正逐渐丧失 ...

Bi/Bi2O3 Nanoparticles In Situ Embedded in Carbon as Anode Materials for Fast and Long‐Lasting Sodium–Ion Storage

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Bismuth anode materials are considered promising anode candidates for sodium–ion batteries (SIBs) due to their high theoretical capacity and appropriate working potential. Nevertheless, the significant volume expansion that occurs during the cycling process restricts its broader application in sodium–ion storage. Herein, Bi/Bi2O3 nanoparticles

In Situ Formation of the Li3Bi Alloy Phase Interface for Robust Garnet Solid‐State Lithium Batteries

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Garnet‐type electrolyte Li6.4La3Zr1.4Ta0.6O12 (LLZTO) is a promising component for commercializing solid‐state batteries owing to its wide electrochemical window, good stability, and high shear modulus. However, poor interface wettability and lithium dendrite growth limit the practical application of the LLZTO electrolyte.

鹰潭小流域季节性降雨径流特征研究

open access: yesShuitu Baochi Xuebao, 2003
降雨是影响低丘红壤坡地土壤侵蚀和养分随径流迁移的一个关键因子.利用三角量 水堰自动测量径流量和自动雨量计观测数据,分析了鹰潭小流域的季节性降雨径流特征.小流域降雨主要发生在4~6月,总量达512.4 mm,占观测时段总雨量的70.1%,而旱季7~9月仅为218.9 mm.上游、下游围堰累积径流量随旱季、雨季的变化表明:小流域降雨-径流- 土壤水界面水分转化可分为土壤水补给阶段(4月14日~6月14日)、土壤水饱和阶段(6月15 日~7月28日)和土壤水消耗阶段(7月28日以后 ...
