Integrating marine fungi into structure

项目摘要

Even though marine fungi have been known to exist since the 19th century, the application of molecular ecology tools has established a foundational understanding of the widespread distribution and diversity of the ocean mycobiome. Recent evidence has indicated the functional roles fulfilled by planktonic fungi (mycoplankton) in open water ecosystems. Some marine mycoplankton are apparent saprotrophs that utilise high-molecular weight substrates via extracellular enzymes, whilst others are potential parasites of phytoplankton, particularly diatoms. A novel and open research question is to understand how marine mycoplankton fit within the wider structure and function of pelagic marine ecosystems. This research is timely because of the development of approaches to study marine fungi in the laboratory and in situ. Saprotrophy is an already well-established functional role of marine bacterioplankton and it is currently unknown how fungal and bacterial saprotrophy are interrelated. Even though fungal parasitism of marine phytoplankton is known, the prevalence and importance of phytoplankton parasitism and change through time and space remain largely speculated. This aim of this PhD project is to address these knowledge gaps through an integrated and complementary programme of laboratory, field and modelling based approaches

尽管海洋真菌自19世纪以来就已存在，但分子生态学工具的应用已建立了对海洋真菌群落广泛分布和多样性的基本认识。最近的证据表明，在开放水域生态系统中，浮游真菌（浮游真菌）发挥着功能性作用。一些海洋浮游真菌是通过胞外酶利用高分子量底物的明显腐养生物，而另一些则是浮游植物，特别是硅藻的潜在寄生虫。一个新的和开放的研究问题是了解海洋浮游真菌如何适应更广泛的结构和功能的远洋海洋生态系统。这项研究是及时的，因为在实验室和原位研究海洋真菌的方法的发展。腐殖作用是海洋浮游细菌的一个已经确立的功能作用，目前还不清楚真菌和细菌腐殖作用是如何相互关联的。尽管海洋浮游植物的真菌寄生是已知的，浮游植物寄生的流行和重要性以及随时间和空间的变化仍然在很大程度上是推测的。这个博士项目的目的是通过实验室，现场和基于模型的方法的综合和互补方案来解决这些知识差距
