An ecotoxicological view on neurotoxicity assessment

The numbers of potential neurotoxicants in the environment are raising and pose a great risk for humans and the environment. Currently neurotoxicity assessment is mostly performed to predict and prevent harm to human populations. Despite all the efforts in ...

A generalized definition of reactivity for ecological systems and the problem of transient species dynamics

Andrea Rinaldo, Lorenzo Mari

Perturbations to an ecosystem's steady state can trigger transient responses of great ecological relevance. Asymptotic stability determines whether a generic perturbation will fade out in the long run, but falls short of characterizing the dynamics imme ...

Bacterial Whole Cell Typing by Mass Spectra Pattern Matching with Bootstrapping Assessment

Hubert Girault, Yu Lin, Liang Qiao

Bacterial typing is of great importance in clinical diagnosis, environmental monitoring, food safety analysis, and biological research. Matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) is now widely used to analyze bacterial samples ...

Attached biofilms and suspended aggregates are distinct microbial lifestyles emanating from differing hydraulics

Tom Ian Battin, Hannes Markus Peter

Small-scale hydraulics affects microbial behaviour at the cell level1, trophic interactions in marine aggregates2 and the physical structure and function of stream biofilms3,4. However, it remains unclear how hydraulics, predictably changing from small str ...

Application of remote sensing for the optimization of in-situ sampling for monitoring of phytoplankton abundance in a large lake

Alfred Johny Wüest, Damien Bouffard, Isabel Blanca Sophie Kiefer

Directives and legislations worldwide aim at representatively and continuously monitoring the ecological status of surface waters. In many countries, chlorophyll-a concentrations (CHL) are used as an indicator of phytoplankton abundance and the trophic lev ...

Generalized receptor law governs phototaxis in the phytoplankton Euglena gracilis

Andrea Rinaldo, Amos Maritan, Andrea Giometto, Florian Altermatt

Phototaxis, the process through which motile organisms direct their swimming toward or away from light, is implicated in key ecological phenomena (including algal blooms and diel vertical migration) that shape the distribution, diversity, and productivity ...

Silver nanoparticle effects on simple stream food webs and ecosystem processes : periphyton-grazer system

Carmen Omayra Gil Allué

With the global nanotechnology market growing rapidly, nanomaterials are being increasingly released into aquatic environments, where they can undergo modifications and sedimentation, which will put benthic organisms at risk. Of particular interest is the ...

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 ...
