Biofilm communities on intertidal mudflats are recognized as major producers of nutrients, especially fatty acids. The rising threats posed by both climatic and anthropogenic stressors increase the necessity of understanding and conserving these communities. Shorebirds provide a proxy for studying the complex ecology of biofilm communities because of their heavy reliance on fatty acids from diatomaceous biofilm for successful long-distance migration. Herein, we review biofilm feeding patterns by migratory shorebirds, experimental design considerations for sampling and studying the fatty acid content of biofilm, and the literature describing established and emerging analytical methodology. Techniques for fatty acid analysis include the commonly employed gas chromatography–flame ionization detection (GC/FID) and gas chromatography–mass spectrometry (GC/MS) with derivatization. Liquid chromatography–mass spectrometry (LC/MS) and liquid chromatography–quadrupole time of flight (LC/QTOF) are newly emerging techniques that enable derivatization to be eliminated. In addition, Fourier transform infrared spectroscopy (FT/IR), a common instrument in chemistry laboratories, has applications in fatty acid research, specifically for screening. Using a combination of sampling and analytical methods is necessary for improved understanding of intertidal biofilm, both as a source of essential fatty acids in aquatic systems and a critical food for shorebirds.

潮间带生物膜中硅藻介导的脂肪酸评估:一个新的保护问题

潮间带滩涂上的生物膜群落被认为是养分特别是脂肪酸的主要生产者。气候和人为压力源构成的威胁不断增加,这就增加了了解和保护这些社区的必要性。由于bird鸟严重依赖硅藻生物膜中的脂肪酸来成功进行长距离迁移,因此它们为研究生物膜群落的复杂生态提供了一种代理。在这里,我们回顾了迁徙的水鸟的生物膜喂养模式,采样和研究生物膜脂肪酸含量的实验设计考虑因素,以及描述已建立和正在出现的分析方法的文献。脂肪酸分析技术包括常用的气相色谱-火焰电离检测(GC / FID)和气相色谱-质谱联用法(GC / MS)。液相色谱-质谱(LC / MS)和液相色谱-四极杆飞行时间(LC / QTOF)是新兴技术,可以消除衍生化作用。另外,化学实验室中常用的仪器傅立叶变换红外光谱(FT / IR)在脂肪酸研究中,特别是在筛选中具有应用。为了更好地了解潮间生物膜,将取样和分析方法结合起来是必要的,潮间生物膜既是水生系统中必需脂肪酸的来源,又是shore的重要食物。液相色谱-质谱(LC / MS)和液相色谱-四极杆飞行时间(LC / QTOF)是新兴技术,可以消除衍生化作用。另外,化学实验室中常用的仪器傅立叶变换红外光谱(FT / IR)在脂肪酸研究中,特别是在筛选中具有应用。为了更好地了解潮间生物膜,将取样和分析方法结合起来是必要的,潮间生物膜既是水生系统中必需脂肪酸的来源,又是shore的重要食物。液相色谱-质谱(LC / MS)和液相色谱-四极杆飞行时间(LC / QTOF)是新兴技术,可以消除衍生化作用。另外,化学实验室中常用的仪器傅立叶变换红外光谱(FT / IR)在脂肪酸研究中,特别是在筛选中具有应用。为了更好地了解潮间生物膜,将取样和分析方法结合起来是必要的,潮间生物膜既是水生系统中必需脂肪酸的来源,又是shore的重要食物。专门用于筛选。为了更好地了解潮间生物膜,将取样和分析方法结合起来是必要的,潮间生物膜既是水生系统中必需脂肪酸的来源,又是shore的重要食物。专门用于筛选。为了更好地了解潮间生物膜,将取样和分析方法结合起来是必要的,潮间生物膜既是水生系统中必需脂肪酸的来源,又是shore的重要食物。
