Long-term impacts of nutrient control, climate change, and invasive clams on phytoplankton and cyanobacteria biomass in a large temperate river

Recent studies suggest that climate change, with warmer water temperatures and lower and longer low flows, may enhance harmful planktic cyanobacterial growth in lakes and large rivers. Concomitantly, controlling nutrient loadings has proven effective in re ...

A perspective view on the nanomotion detection of living organisms and its features

Giovanni Dietler, Sandor Kasas, María Inés Villalba, Anne-Céline Verenna Kohler, Giovanni Longo, Petar Stupar, Leonardo Venturelli, Massimiliano Bertacchi

The insurgence of newly arising, rapidly developing health threats, such as drug-resistant bacteria and cancers, is one of the most urgent public-health issues of modern times. This menace calls for the development of sensitive and reliable diagnostic tool ...

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 ...

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 ...

Identifying contaminated sediment problems associated with urban stormwater discharges in lakes

Tom Hugo Antoine Benejam

Urban stormwater discharges during wet weather has always been a sensitive issue to deal with. By inducing combined sewer overflows, substantial impacts on receiving water are commonly feared. Aware of this problematic situation, the VSA already created th ...

Correlated TEM-NanoSIMS investigation of foraminiferal metabolism

Charlotte Madeleine Nicole Lekieffre

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 ...

Per- and poly-fluoroalkyl compounds in freshwater fish from the Rhone River: Influence of fish size, diet, prey contamination and biotransformation

Pools of aquatic plants and benthic invertebrates were collected along with 47 individuals from three cyprinid fish species (Barbus barbus, Gobio gobio, Rutilus rutilus) at a site in the Rhone River (France). Carbon and nitrogen isotopic ratios (delta C-13 ...

Macroinvertebrate community traits and nitrate removal in stream sediments

Tom Ian Battin

In-stream nitrate removal capacity may be used as a proxy for the ecosystem service of water quality regulation. It is well known that this natural function is driven by abiotic and biotic factors in running water environments. With regard to biotic dri ...
