An overview of cellular ultrastructure in benthic foraminifera: New observations of rotalid species in the context of existing literature

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

We report systematic transmission electron microscope (TEM) observations of the cellular ultrastructure of selected, small rotalid benthic foraminifera. Nine species from different environments (intertidal mudflat, fjord, and basin) were investigated: Ammo ...

Ultrastructure and distribution of kleptoplasts in benthic foraminifera from shallow-water (photic) habitats

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

Assimilation, sequestration and maintenance of foreign chloroplasts inside an organism is termed “chloroplast sequestration” or “kleptoplasty”. This phenomenon is known in certain benthic foraminifera, in which such kleptoplasts can be found both intact an ...

Cellular pathways of carbon and nitrogen assimilation in kleptoplastic foraminiferal species

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

Kleptoplasty is the process by which an organism sequesters algal chloroplasts while discarding or digesting other algal components. This ability is encountered in different organisms, including benthic foraminifera. Among kleptoplastic foraminiferal speci ...

Innovative TEM-coupled approaches to study foraminiferal cells

Anders Meibom, Stéphane Laurent Escrig, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

Transmission electron microscope (TEM) observation has revealed much about the basic cell biology of foraminifera. Yet, there remains much we do not know about foraminiferal cytology and physiology, especially for smaller benthic foraminifera, which inhabi ...

Surviving anoxia in marine sediments: The metabolic response of ubiquitous benthic foraminifera (Ammonia tepida)

Anders Meibom, Stéphane Laurent Escrig, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

High input of organic carbon and/or slowly renewing bottom waters frequently create periods with low dissolved oxygen concentrations on continental shelves and in coastal areas; such events can have strong impacts on benthic ecosystems. Among the meiofauna ...

Foraminifera are ubiquitous eukaryotic protists inhabiting all types of marine environments. The chemical and isotopic compositions of their carbonate tests are commonly used as proxies for paleo-environmental conditions. However, while foraminifera repres ...

Spatial distribution and biological effects of trace metals (Cu, Zn, Pb, Cd) and organic micropollutants (PCBs, PAHs) in mussels Mytilus galloprovincialis along the Algerian west coast

Dominique Grandjean, Luiz Felippe De Alencastro

Native mussels Mytilus galloprovincialis are used as bioindicator organisms to assess the concentration levels and toxic effects of persistent chemicals, polychlorobiphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), and heavy metals using biomarker ...

Chapter 4.2.1 : The Microbial Ecology of Benthic Environments

Tom Ian Battin

Within the benthic realm life carpets the sedimentary surface of all aquatic ecosystems including the oceans, lakes, rivers and streams. Microorganisms of all types, bacteria, archaea and eukaryotes, inhabit these environments and through their metabolic a ...
