短链脂肪酸(SCFA)在健康和疾病中发挥着关键作用,因为它们调节肠道稳态,其缺乏参与了多种疾病的发病机制,包括炎症性肠病、结直肠癌和心脏代谢疾病。SCFA是人类肠道微生物群中特定细菌类群的代谢产物,它们的产生受到特定食物或食物补充剂的影响,主要是益生元这些类群的直接培养。在本综述中, 作者概述了SCFA的结构,作用和功能,以及产生SCFA的细菌,从它们的微生物特征和分类到导致SCFA释放的生化过程...
Phytoplankton are the foundation of ocean ecosystems: like rainforests, they consume carbon from the atmosphere, form the basis of the marine food web and have a decisive influence on fish abundance a...
Losses of important eelgrass meadows in western Sweden since the 1980s have led to considerable bottom erosion and the release of carbon and nitrogen; substances that contribute to increasing climate ...
A new study by National Science Foundation-funded researchers at the Woods Hole Oceanographic Institution and their colleagues found that freshwater runoff from rivers and continental s...
Feedbacks between flooding and plant growth that help to stabilize marshes against rising sea level are being investigated in estuaries at Plum Island, Massachusetts, and North Inlet, South Carolina. ...
Diversity of life abounds on Earth, and there's no need to look any farther than the ocean's surface for proof. There are over 200,000 species of phytoplankton alone, and all of those species of micro...
Recently, the potential for biochar use to recapture excess nutrients from dairy wastewater has been a focus of a growing number of studies. It is suggested that biochar produced from locally availabl...
Background: Complementary feeding recommendations (CFRs) with the use of locally available foods can be developed by using linear programming (LP). Although its potential has been shown for planning p...
We examined the separate and interactive effects of light, nutrients, and zooplanktivorous fish on phytoplankton nutrient stoichiometry, taxonomic richness, community composition, and the association...
Oceanographers hThe phrase, ‘Eat your vitamins,’ applies to marine animals just like humans. Many vitamins are elusive in the ocean environment.University of Washington researchers used new tools to m...
Simple general equations are used to show that when riverine water mixes with seawater, the N : P ratio is a nonlinear function of salinity. Thus, a shift in the limiting-nutrient status at a particu...
Comment: Temperature, nutrients, and the size-scaling of phytoplankton growth in the sea。
To assess the significance of nutrient interactions on animal performance, life-history experiments were conducted with the freshwater herbivore Daphnia magna in a system with two limiting nutrients ...
We compile two data sets from14C uptake and dilution experiments conducted in surface waters of the global ocean to investigate the relationship between phytoplankton mass-specific growth rate and cel...
Factor analysis investigated the relationship between different compounds of nitrogen, phosphorus, potassium and suspended dry matter in runoff from catchments in agricultural areas in southern and ...
