BENTHIC MACROFAUNA CONSUMPTION BY WATER BIRDS [PDF]
, 2011 The diversity and abundance of birds present in intertidal coastal ecosystems are closely related to the biomass of benthic invertebrates. The assessment of energy consumed compared with the available resource is one of the fundamental aspects of ...

Macrofaunal colonization of mine tailings impacted sediments
Science of The Total Environment, 2020 An experiment was conducted to study and compare macrofaunal colonization of thin layers of mine tailings. Experimental boxes filled with marine sediments capped with mine tailings were placed on the seabed and subject to colonization for six and twelve months. Three Norwegian mine tailings, representative of major production processes, were used.

Macrofaunal sediment selectivity considerations for beach nourishment programmes [PDF]
Marine Environmental Research, 2013 Nowadays, beach nourishment is widely considered as a better alternative compared to the construction of hard structures to protect a sandy coast against detrimental erosive effects, both from an ecological and an engineering perspective. The rare studies conducted on the ecological impact of beach nourishment are short-term, post hoc monitoring ...

Potential impacts of marine urbanization on benthic macrofaunal diversity [PDF]
Scientific Reports, 2021 AbstractUrbanization and associated human activities have caused numerous changes to natural environments, including the loss of natural habitats and replacement with artificial structures. How these changes impact coastal marine biodiversity and ecosystem functioning is not well known.

Inhibition of denitrification by hydrocarbons in marine sediments. Role of Nereis diversicolor [PDF]
, 1997 An in vitro experiment has been carried out in order to illustrate the influence of the burrowing polychaete Nereis diversicolor on denitrification in hydrocarbon-loaded sediments.

Interaction entre le système de culture et le statut (ravageur ou auxiliaire) des vers blancs (Coleoptera : Scarabeoidea) sur le riz pluvial [PDF]
, 2013 A Madagascar, les larves et adultes terricoles de certaines espèces de Coléoptères Scarabeoidea causent d'importants dégâts au riz pluvial. Le traitement insecticide des semences assure une protection efficace, mais son impact environnemental soupçonné ...

Macrofaunal consumption as a mineralization pathway
, 2022 We discuss the significance of macrofaunal consumption as a process for mineralization of organic carbon in vegetated coastal wetlands, particularly mangrove forests. The high productivity of macrophytes (salt marsh and mangrove plants) in coastal wetlands results in high availability of organic matter generally recalcitrant to mineralization.

Effects of hypoxia on benthic macrofauna and bioturbation in the Estuary and Gulf of St. Lawrence, Canada [PDF]
, 2010 The bottom water in the 4300 m deep Lower St. Lawrence Estuary (LSLE) is persistently hypoxic in contrast to the normoxic bottom waters in the Gulf of St. Lawrence (GSL). We photographed the seabed at 11 stations in the Estuary and Gulf of St.

Habitat heterogeneity influences cold‐seep macrofaunal communities within and among seeps along the Norwegian margin. Part 1: macrofaunal community structure [PDF]
Marine Ecology, 2011 AbstractHåkon Mosby mud volcano (HMMV) is one of the most active and most studied seep sites in European waters. Many authors have described its thermal activity, dynamic of mud flows, and geochemical and microbial processes. It is characterised by a concentric zonation of successive biogenic habitats related to an activity and geochemical gradient ...
