The combined action of macrofauna, inclusive of fish, macrophytes, and birds, is an important driver of aquatic nutrient cycling. Fish and birds supply and translocate nutrients via direct (excretion) and indirect pathways (bioturbation, sediment resuspension, predation) at rates comparable to other nutrient sources. Consumer-mediated recycling may support a large fraction of the nutrient requirements by primary producers thereby offsetting management efforts to mitigate eutrophication. Fish and birds also alter the relative availability and ecological stoichiometry of nitrogen, silica and phosphorus, with cascade effects on species composition and ecosystem functioning. Macrophytes retain nutrients in biomass via uptake processes and favor their burial and long term retention within sediments. Rooted macrophytes produce a number of indirect effects on pore water nutrients, by stimulating via radial oxygen loss biogeochemical processes such as coupled nitrification-denitrification or precipitation. The effects of fish, birds and macrophytes on aquatic nutrient cycling is a complex issue, as it involves multiple feedbacks and synergistic interactions, often understudied. These effects likely vary along environmental gradients, such as nutrient and organic matter availability, salinity and ecosystem size. This Special Issue targets contributions focusing on the effects of macrofauna, on nutrient cycling with the goal of providing a more comprehensive understanding of their importance among diverse aquatic systems.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
