小型中上层鱼类（SPF）在海洋生态系统中发挥着极其重要的生态作用，构成了一些最具经济价值的渔业资源，并在全球粮食安全中发挥着至关重要的作用。由于其短世代时间和紧密耦合到较低的营养水平，SPF人口显示大繁荣和萧条的动态，与气候变化密切相关。为了揭示全球SPF研究的新趋势，而不是最近发表的SPF生态系统特定的评论，我们回顾了新千年（2001-2006年和2011-2016年）两个6年期间发表的文献，其中包括2009年发表的一份大型SPF动态全球评论。我们探讨了内在和外在（自下而上）的因素影响的动态SPF，如鲱鱼，沙丁鱼，鲱鱼和鲱鱼内的子命令鲱科。对16个不同海洋地理区域内发表的研究成果进行了汇编（900多项研究），并进行了比较，以确定i）我们理解的新里程碑和进展，ii）新兴的研究趋势和iii）剩余的知识差距。研究分为5类（现场，实验室，中生态系统，长期统计分析和空间明确的建模），并讨论了10个自下而上的类别，包括5个非生物因素（温度，盐度，pH值，溶解氧，密度），3个物理过程（平流，湍流，浊度）和2个生物因素（猎物的数量和质量）。同行评审文献反映了两个时间段之间研究数量的变化，包括增加（地中海，洪堡海流）和减少（澳大利亚，本格拉海流）。我们的综述强调了i）关于幼鱼的生态学知识的空白，以及缺氧和热浪对SPF的影响，ii）古研究在探索种群驱动因素方面的效用，iii）继续需要开发空间明确的全生命周期模型，iv）探索密度依赖过程如何影响生命率的重要性（生长，生存，繁殖），以及v）国际合作的好处，知识转让和建立统一的假设的作用，自下而上的因素和过程，调节SPF人口。
Small pelagic fish (SPF) play extremely important ecological roles in marine ecosystems, form some of the most economically valuable fisheries resources, and play a vital role in global food security. Due to their short generation times and tight coupling to lower trophic levels, populations of SPF display large boom-and-bust dynamics that are closely linked to climate variability. To reveal emerging global research trends on SPF as opposed to more recently published, ecosystem-specific reviews of SPF, we reviewed the literature published in two, 6-year periods in the new millennium (2001–2006, and 2011–2016) straddling the publication of a large, global review of the dynamics of SPF in 2009. We explored intrinsic and extrinsic (bottom-up) factors influencing the dynamics of SPF such as anchovies, sardines, herrings and sprats within the sub-order Clupeidae. Published research efforts within 16 different biogeographic ocean regions were compiled (more than 900 studies) and compared to identify i) new milestones and advances in our understanding, ii) emerging research trends and iii) remaining gaps in knowledge. Studies were separated into 5 categories (field, laboratory, mesocosms, long-term statistical analyses and spatially-explicit modelling) and discussed in relation to 10 bottom-up categories including 5 abiotic factors (temperature, salinity, pH, dissolved oxygen, density), 3 physical processes (advection, turbulence, turbidity) and 2 biotic factors (prey quantity and quality). The peer-reviewed literature reflects changes in the number of studies between the two time periods including increases (Mediterranean Sea, Humboldt Current) and decreases (Australia, Benguela Current). Our review highlights i) gaps in ecological knowledge on young juveniles and, in general, on the impacts of hypoxia and heatwaves on SPF, ii) the utility of paleo studies in exploring population drivers, iii) the continued need to develop spatially-explicit, full life-cycle models, iv) the importance of exploring how density-dependent processes impact vital rates (growth, survival, reproduction), and v) the benefits of international collaboration for knowledge transfer and building unifying hypotheses on the role of bottom-up factors and processes that regulate SPF populations.
