The clogging of riverbeds: A review of the physical processes

Giovanni De Cesare, Romain Maxime Dubuis

Fine sediment represents an important part of the solid flux of rivers. Due to the size of these particles, they are often transported as suspended load. They gradually fill the pores of the substrate forming the hyporheic zone or cover the substrate by se ...

Coral holobiont cues prime Endozoicomonas for a symbiotic lifestyle

Nils Rädecker, Claudia Isabella Pogoreutz, Gabriela Hannah Holligan Perna

Endozoicomonas are prevalent, abundant bacterial associates of marine animals, including corals. Their role in holobiont health and functioning, however, remains poorly understood. To identify potential interactions within the coral holobiont, we character ...

Elucidating the present-day chemical composition, seasonality and source regions of climate-relevant aerosols across the Arctic land surface

Julia Schmale, Imad El Haddad

The Arctic is warming two to three times faster than the global average, and the role of aerosols is not well constrained. Aerosol number concentrations can be very low in remote environments, rendering local cloud radiative properties highly sensitive to ...

Highly motile nanoscale magnetic artificial cilia

Yves Bellouard, Tanveer Ul Islam

Among the many complex bioactuators functioning at different scales, the organelle cilium represents a fundamental actuating unit in cellular biology. Producing motions at submicrometer scales, dominated by viscous forces, cilia drive a number of crucial b ...

Functional kleptoplasts intermediate incorporation of carbon and nitrogen in cells of the Sacoglossa sea slug Elysia viridis

Anders Meibom, Stéphane Laurent Escrig, Charlotte Madeleine Nicole Lekieffre, Michael Kühl

Some sacoglossan sea slugs incorporate intracellular functional algal chloroplasts, a process termed kleptoplasty. "Stolen" chloroplasts (kleptoplasts) can remain photosynthetically active up to several months, contributing to animal nutrition. Whether thi ...

A modern scleractinian coral with a two-component calcite–aragonite skeleton

Anders Meibom, Jaroslaw Hubert Stolarski

One of the most conserved traits in the evolution of biomineralizing organisms is the taxon-specific selection of skeletal minerals. All modern scleractinian corals are thought to produce skeletons exclusively of the calcium-carbonate polymorph aragonite. ...

Towards simple tools to assess functional effects of contaminants on natural microbial and invertebrate sediment communities

Benoît Jean Dominique Ferrari, Maria del Carmen Casado Martinez, Sophie Campiche

Surface sediments can accumulate contaminants that affect microorganisms and invertebrates and disturb benthic ecological functions. However, effects of contaminants on ecological functions supported by sediment communities are understudied. Here, we teste ...

Life-history trade-offs and limitations associated with phenotypic adaptation under future ocean warming and elevated salinity

Emma Mary Gibbin, Félix Christen

Little is known about the life-history trade-offs and limitations, and the physiological mechanisms that are associated with phenotypic adaptation to future ocean conditions. To address this knowledge gap, we investigated the within-and trans-generation li ...

Amorphous CaCO3: Influence of the Formation Time on Its Degree of Hydration and Stability

Francesco Stellacci, Huachuan Du, Esther Amstad, Camelia Borca, Mathias Steinacher, Anna Murello

Calcium carbonate (CaCO3) is one of the most abundant biominerals that is prevalent in rocks and often used as a structural material in marine animals. Many of these natural CaCO3-based materials display excellent mechanical properties that are difficult t ...

Enhanced Iron Solubility at Low pH in Global Aerosols

Athanasios Nenes, Kalliopi Violaki, Yan Feng

The composition and oxidation state of aerosol iron were examined using synchrotron-based iron near-edge X-ray absorption spectroscopy. By combining synchrotron-based techniques with water leachate analysis, impacts of oxidation state and mineralogy on aer ...
