The effect of bio-irrigation by the polychaete Lanice conchilega on active denitrifiers: Distribution, diversity and composition of nosZ gene Instituut voor Landbouw-, Visserij- en Voedingsonderzoek Plantentuin Meise / Agentschap Plantentuin Meise Universiteit Gent
The presence of large densities of the piston-pumping polychaete Lanice conchilega can have important consequences for the functioning of marine sediments. It is considered both an allogenic and an autogenic ecosystem engineer, affecting spatial and temporal biogeochemical gradients (oxygen concentrations, oxygen penetration depth and nutrient concentrations) and physical properties (grain size) of marine sediments, which could affect functional ...

Alkalinity production in intertidal sands intensified by lugworm bioirrigation Vrije Universiteit Brussel
Porewater profiles and sediment-water fluxes of oxygen, nutrients, pH, calcium, alkalinity, and sulfide were measured in intertidal sandflat sediments from the Oosterschelde mesotidal lagoon (The Netherlands). The influence of bioturbation and bioirrigation by the deep-burrowing polychaete Arenicola marina on the rates and sources of benthic alkalinity generation was examined by comparing measurements in intact and defaunated sediment cores ...

Increased densities of the bio-irrigator Lanice conchilega affect composition and diversity of nosZ transcripts Plantentuin Meise / Agentschap Plantentuin Meise
Increased densities of the bio-irrigator Lanice conchilega affect composition and diversity of nosZ transcripts. The presence of the piston-pumping polychaete Lanice conchilega can induce short term oscillations in oxygen and nitrate availability at deeper sediment layers, affecting the functional properties of local microbial communities. Here, we investigated the effect of Lanice conchilega densities on the expression of the nosZ gene, a gene ...
Spatio-temporal variation in sediment ecosystem processes and roles of key biota in the Scheldt estuary Universiteit Gent
Bioturbation (i.e. particle reworking and bio-irrigation) is a key process in benthic coastal and estuarine ecosystems, and act as crucial control on important ecosystem functions, such as nutrient cycling. Particle reworking and bio-irrigation are affected by a wide array of environmental and biological factors and are therefore expected to be highly variable in heterogeneous ecosystems, such as estuaries. To assess the spatial and temporal ...
