Heatwave intensity drives eco‐physiological responses in infaunal bivalves: A mesocosm experiment
Limnology and Oceanography, EarlyView.Abstract Marine heatwaves are increasing globally in intensity and duration. To investigate the potential consequences for coastal ecosystems, the effects of short‐term heat stress must be better understood. This study examined eco‐physiological responses in two common intertidal bivalves, Cerastoderma edule and Macoma balthica, to different heatwave ...

Modeling eutrophication and oligotrophication of shallow-water marine systems: the importance of sediments under stratified and well-mixed conditions [PDF]
, 2009 A one-dimensional model that couples water-column physics with pelagic and benthic biogeochemistry in a 50-m-deep water column is used to demonstrate the importance of the sediment in the functioning of shallow systems, the eutrophication status of the ...

Limnology and Oceanography, EarlyView.Abstract Nutrient dynamics in headwater streams are governed by benthic and hyporheic biofilms, with carbon (C) : nitrogen (N) : phosphorus (P) ratios driving the heterotrophic microbial biofilm development through nutrient limitation. Furthermore, heterotrophic responses to changes in C : N : P ratios are probably modulated by autotrophic responses to

Benthic macrofauna and sediment reworking quantification in contrasted environments in the Thau Lagoon [PDF]
, 2007 As part of the Microbent-PNEC Program: ‘‘Biogeochemical processes at the wateresediment interface in eutrophicated environment’’, the aim of this work was to specifically investigate and quantify the relationships between macrobenthos and sediment ...

Limnology and Oceanography, EarlyView.Abstract Benthic fluxes are important sources of nutrients and dissolved carbon to the water column. Yet, most approaches for quantifying benthic fluxes are labor intensive and cover relatively small areas of the ocean. Here, we use 224Ra to quantify ecosystem‐scale vertical mixing across a largely hypoxic deep water column in the Baltic Sea and ...

Pre-construction coral survey of the M/V Wellwood Grounding Site: April 23-24, 2002 [PDF]
, 2003 This report documents abundance and cover for selected elements of the benthic coral reef assemblage at the site of the 1984 grounding of the M/V Wellwood on Molasses Reef, Florida Keys.

Influence of nontrophic interactions between benthic invertebrates on river sediment processes: a microcosm study [PDF]
, 2004 The main objective of this study was to measure the impact of benthic invertebrate diversity on river sediment processes. We quantified the effects of interactions between three taxa (asellids, chironomid larvae, and tubificid worms).

Geologica Acta, 2020 A taxonomic study of the larger foraminifera found in Paleocene rocks from the Pyrenean basin has led to the description of sixty taxa including two new species: Alveolina korresensis and Valvulineria bacetai. In this work, we present a chronostratigraphic recalibration of the Paleocene Shallow Benthic Zones (SBZ 1 to SBZ 4) based on correlation with ...

Limnology and Oceanography, EarlyView.Abstract Sediment loading from land and turbidity in coastal waters has increased because of human activities in coastal catchments and through climate‐related increases in storm intensity and frequency. Here, we investigated changes in coastal seafloor biodiversity and ecosystem function across a suspended sediment concentration gradient in a New ...

Habitat and scale shape the demographic fate of the keystone sea urchin Paracentrotus lividus in Mediterranean macrophyte communities [PDF]
, 2012 Demographic processes exert different degrees of control as individuals grow, and in species that span several habitats and spatial scales, this can influence our ability to predict their population at a particular life-history stage given the previous ...
