从沉积 DNA 的角度看环境和食物网变化对琵琶湖微生物真核生物群落的影响
几十年来,人们一直在探索环境变化对琵琶湖的影响,水体监测和古生物学研究揭示了环境胁迫(包括气候变暖、富营养化、水位调节和人类对鱼类种群的操纵)是如何影响琵琶湖食物网的。然而,这些研究很少考虑微生物食物网的组成部分。造成这一知识空白的主要原因是缺乏时间跨度超过几十年的时间序列,再加上识别属于非常多样化群体的生物需要很高的分类学专业知识。使用沉积 DNA 方法可以重建水生系统微生物真核生物群落的多样性、组成和结构在过去的变化。18S 代谢条形码的应用已被证明可以成功地描述湖泊生态系统中单细胞真核生物(原生生物)和水生真菌的反应,包括大量的分类和功能多样性,如光养生物、异养生物和混养生物。我们对琵琶湖过去 100 年间的 31 个沉积物核心样本应用了 18S 代谢编码,并探讨了 1973-2010 年间微生物真核生物群落对多种环境压力变化的响应,包括营养水平、湖水水位、气候以及鱼类和浮游动物生物量的变化。我们发现,水位的调节和鱼类群落组成的变化是(间接)影响湖泊微生物真核生物群落结构的主要因素,气候变暖和磷含量的影响较小,但也很显著。共现网络分析强调了食物网对微生物真核生物群落的潜在影响,表明该区块的生物同时受到自下而上和自上而下过程的影响。

期刊介绍: Freshwater Biology publishes papers on all aspects of the ecology of inland waters, including rivers and lakes, ground waters, flood plains and other freshwater wetlands. We include studies of micro-organisms, algae, macrophytes, invertebrates, fish and other vertebrates, as well as those concerning whole systems and related physical and chemical aspects of the environment, provided that they have clear biological relevance. Studies may focus at any level in the ecological hierarchy from physiological ecology and animal behaviour, through population dynamics and evolutionary genetics, to community interactions, biogeography and ecosystem functioning. They may also be at any scale: from microhabitat to landscape, and continental to global. Preference is given to research, whether meta-analytical, experimental, theoretical or descriptive, highlighting causal (ecological) mechanisms from which clearly stated hypotheses are derived. Manuscripts with an experimental or conceptual flavour are particularly welcome, as are those or which integrate laboratory and field work, and studies from less well researched areas of the world. Priority is given to submissions that are likely to interest a wide range of readers. We encourage submission of papers well grounded in ecological theory that deal with issues related to the conservation and management of inland waters. Papers interpreting fundamental research in a way that makes clear its applied, strategic or socio-economic relevance are also welcome. Review articles (FRESHWATER BIOLOGY REVIEWS) and discussion papers (OPINION) are also invited: these enable authors to publish high-quality material outside the constraints of standard research papers.
