Our BU briefing papers are designed to make our research outputs accessible and easily digestible so that our research findings can quickly be applied – whether to society, culture, public policy, services, the environment or to improve quality of life. They have been created to highlight research findings and their potential impact within their field.
This paper examines seasonal food webs of the invertebrates inhabiting the streambed of the chalk River Lambourn in England. Researchers conducted analyses of gut content (a dietary “snapshot”) of macro and meiofauna, as well as stable isotope analyses (determines the feeding links of an organism as it reflects its assimilated diet) of meiofauna to examine seasonal food webs of the chalk stream.
This study stresses the importance of temporal variations in food and consumer species composition for a comprehensive understanding of food web structure, asserted by similar changes in trophic structure depicted by gut content and stable isotope analyses.
