A global dataset of nitrogen fixation rates across inland and coastal waters [0.03%]
全球内陆和沿海水体固氮率数据集

Robinson W Fulweiler et al.
Biological nitrogen fixation is the conversion of dinitrogen (N2) gas into bioavailable nitrogen by microorganisms with consequences for primary production, ecosystem function, and global climate. Here we present a compiled dataset of 4793 ...
Tracking a large-scale and highly toxic Arctic algal bloom: rapid detection and risk communication [0.03%]
对大规模高毒北极藻华的快速监测与预警跟踪
Evangeline Fachon,Robert S Pickart,Gay Sheffield et al.
Evangeline Fachon et al.
In recent years, blooms of the neurotoxic dinoflagellate Alexandrium catenella have been documented in Pacific Arctic waters, and the paralytic shellfish toxins (PSTs) that this species produces have been detected throughout the food web. T...
Five state factors control progressive stages of freshwater salinization syndrome [0.03%]
五大要素控制淡水盐化症的渐进阶段
Sujay S Kaushal,Paul M Mayer,Gene E Likens et al.
Sujay S Kaushal et al.
Factors driving freshwater salinization syndrome (FSS) influence the severity of impacts and chances for recovery. We hypothesize that spread of FSS across ecosystems is a function of interactions among five state factors: human activities,...
The effects of salinity and N:P on N-rich toxins by both an N-fixing and non-N-fixing cyanobacteria [0.03%]
盐度和N:P比值对固氮和非固氮蓝藻丰富态毒素的影响
Felicia S Osburn,Nicole D Wagner,Raegyn B Taylor et al.
Felicia S Osburn et al.
Freshwater ecosystems are experiencing increased salinization. Adaptive management of harmful algal blooms (HABs) contribute to eutrophication/salinization interactions through the hydrologic transport of blooms to coastal environments. We ...
Nitrogen fixation: a poorly understood process along the freshwater-marine continuum [0.03%]
氮固定：关于淡水-海洋连续体的一个尚不明确的过程
Amy M Marcarelli,Robinson W Fulweiler,J Thad Scott
Amy M Marcarelli
Although N2 fixation is a major component of the global N cycle and has been extensively studied in open-ocean and terrestrial ecosystems, rates and ecological dynamics remain virtually unknown for the inland and coastal aquatic ecosystems ...
Greenhouse gas emissions from lakes and impoundments: upscaling in the face of global change [0.03%]
全球变化下的湖泊和水库温室气体排放通量估算及归因分析研究进展
Tonya DelSontro,J J Beaulieu,John A Downing
Tonya DelSontro
Lakes and impoundments are important sources of greenhouse gases (GHG: i.e., CO2, CH4, N2O), yet global emission estimates are based on regionally-biased averages and elementary upscaling. We assembled the largest global dataset to date on ...
Evidence for regional aeolian transport of freshwater micrometazoans in arid regions [0.03%]
干旱地区区域性淡水微动物气载传输的证据
J A Rivas Jr,J Mohl,R S Van Pelt et al.
J A Rivas Jr et al.
While separated by large expanses of dry terrain unsuitable for aquatic biota, aridland waters possess high biodiversity. How aquatic micrometazoans disperse to, and colonize, these isolated ephemeral habitats are not well understood. We us...
Dynamic processing of DOM: Insight from Exometabolomics, Fluorescence Spectroscopy, and Mass Spectrometry [0.03%]
基于代谢组学、荧光光谱及质谱的DOM动态解析机制研究
H J Smith,M Tigges,J D&#x;Andrilli et al.
H J Smith et al.
Dissolved organic matter (DOM) in freshwater environments is an important source of organic carbon, supporting bacterial respiration. Frozen environments cover vast expanses of our planet, with glaciers and ice-sheets storing upwards of six...
