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 ...

DNA-uptake pilus of Vibrio cholerae capable of kin-discriminated auto-aggregation

Melanie Blokesch, Sandrine Stutzmann, Candice Stoudmann, David William Adams

Natural competence for transformation is a widely used and key mode of horizontal gene transfer that can foster rapid bacterial evolution. Competent bacteria take-up DNA from their environment using Type IV pili, a widespread and multi-purpose class of cel ...

Unveiling exceptional Baltic bog ecohydrology, autogenic succession and climate change during the last 2000 years in CE Europe using replicate cores, multi-proxy data and functional traits of testate amoebae

Vincent Eric Jules Jassey, Mariusz Lamentowicz

We present the results of high-resolution, multi-proxy palaeoecological investigations of two parallel peat cores from the Baltic raised bog Mechacz Wielki in NE Poland. We aim to evaluate the role of regional climate and autogenic processes of the raised ...

Structured light enables biomimetic swimming and versatile locomotion of photoresponsive soft microrobots

Peer Fischer, Tian Qiu, Hao Zeng

Microorganisms move in challenging environments by periodic changes in body shape. In contrast, current artificial microrobots cannot actively deform, exhibiting at best passive bending under external fields. Here, by taking advantage of the wireless, scal ...

Basal body structure in Trichonympha

Pierre Gönczy, Paul Guichard

Trichonympha is a symbiotic flagellate of many species of termites and of the wood-feeding cockroach. Remarkably, this unicellular organism harbors up to over ten thousand flagella on its surface, which serve to propel it through the viscous environment of ...

Subcellular Investigation of Photosynthesis-Driven Carbon and Nitrogen Assimilation and utilization in the Symbiotic Reef Coral: Pocillopora damicornis

Anders Meibom, Stéphane Laurent Escrig, Isabelle Domart-Coulon, Christophe Kopp

UNLABELLED: Reef-building corals form essential, mutualistic endosymbiotic associations with photosynthetic Symbiodinium dinoflagellates, providing their animal host partner with photosynthetically derived nutrients that allow the coral to thrive in oligot ...

Silver nanoparticle toxicity and association with the alga Euglena gracilis

Kristin Schirmer, Laura Sigg, Renata Behra, Xiaomei Li, Laetitia Bernard

The impact of silver nanoparticles (AgNPs) on aquatic algae has largely been studied with model species that possess a rigid cell wall. Here, we explored the interactions of AgNPs with Euglena gracilis, a green alga having no cell wall but a pellicle. The ...

Hydrological dynamics and fire history of the last 1300 years in western Siberia reconstructed from a high-resolution, ombrotrophic peat archive

Alexandre Buttler, Vincent Eric Jules Jassey, Mariusz Lamentowicz

Siberian peatlands provide records of past changes in the continental climate of Eurasia. We analyzed a core from Mukhrino mire in western Siberia to reconstruct environmental change in this region over the last 1300 years. The pollen analysis revealed lit ...

The Response of the Mediterranean Gorgonian Eunicella singularis to Thermal Stress Is Independent of Its Nutritional Regime

Alexandre Buttler, Leïla Ezzat

Over the last few decades, sessile benthic organisms from the Mediterranean Sea have suffered from the global warming of the world's oceans, and several mass mortality events were observed during warm summers. It has been hypothesized that mortality could ...
