▪ Abstract Animals are important in nutrient cycling in freshwater ecosystems. Via excretory
processes, animals can supply nutrients (nitrogen and phosphorus) at rates comparable to …

Sediment dwelling, microscopic primary producers, that occupy sediments in the photic
zone, are commonly referred to as microphytobenthos (MPB). The MPB are essential …

Sediments play a key role in the marine nitrogen cycle and can act either as a source or a
sink of biologically available (fixed) nitrogen. This cycling is driven by a number of microbial …

We used a combination of field and laboratory approaches to address how the bioturbation
activity of two crustaceans, the ghost shrimp Neotrypaea californiensis and the fiddler crab …

A mesocosm experiment was conducted to quantify the effects of medium term (5 wk)
exposure to acidified seawater on the structure of Nereis virens (Polychaeta) burrows and …

The aim of this study was to determine the effect of burrowing by natural populations of
Trypaea australiensis on benthic metabolism, nutrient flux, denitrification and irrigation rates …

This article focuses on the ecological role of benthic macrofauna on nutrient dynamics and
benthic-pelagic coupling in the Baltic Sea with relation to eutrophication. Generally, benthic …

Due to increasing nitrogen concentrations in surface waters (6) and eutrophication of coastal
waters (14, 26, 51), the quantification of denitrification rates in sediments of lakes, rivers, and …

Microfibers often dominate sediment microplastic samples, but little is known about their
ecological effects on benthic organisms and functions. Polyethylene terephthalate)(PET) …

1. Nitrogen (N) and phosphorus (P) fluxes via excretion by benthic invertebrates were
quantified in a eutrophic reservoir (Acton Lake, Ohio, USA). We quantified variation in …
