UNDERSTANDING THE EXTENT OF FOOD WEB ALTERATIONS ON AQUATIC ECOSYSTEM STRUCTURE AND FUNCTION REQUIRES CAREFUL CONSIDERATION OF SCALE

Species declines due to changing environmental conditions or anthropogenic influences such as fisheries harvest as well as species introductions probably have consequences beyond the species by also altering their food webs. The scope of the effect on the ...

Contribution to the design methodologies of piled raft foundations under combined loadings

Lyesse Laloui

Although simplified methods have been proposed to allow for group effect and soil-pile-raft interaction, most of them are concentrated on one type of loading rendering the applicability of these methods rather limited to cases under such loads. In the case ...

Subordinate plant species moderate drought effects on earthworm communities in grasslands

Alexandre Buttler, Claire Guenat, Pierre Rémi Mariotte, Renée-Claire Le Bayon

Loss of plant diversity resulting from forecasted drought events is likely to alter soil functioning and affect earthworm communities. Plant-soil interactions are expected to play an important role in mediating climate change effects on soil decomposers. I ...

Silver nanoparticle effects on simple stream food webs and ecosystem processes

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 ...

Performance of a Reinforced Concrete Box Culvert Installed in Trapezoidal Trenches

Liang Sun, Baoguo Chen

The performance of embankment installation (EI) and trench installation (TI) culverts has been investigated through experimental, numerical, and analytical methods. However, there are few studies on the performance of trapezoidal TI (TTI) culverts. Therefo ...

Nitrogen limitation and microbial diversity at the treeline

Alexandre Buttler, Julien Roy, Aurélie Thébault

Tree growth limitation at treeline has mainly been studied in terms of carbon limitation while effects and mechanisms of potential nitrogen (N) limitation are barely known, especially in the southern hemisphere. We investigated how soil abiotic properties ...

On the biomechanics of seedling anchorage

Paolo Perona, Benoît Crouzy, Katharina Maria Edmaier

We propose a minimal model for the response of vegetation to pullout constraints at early development stage. We try to capture both the average mechanical properties of the root system and the stochastic component of the uprooting process of seedlings. We ...

Biomechanics of plant anchorage at early development stage

Paolo Perona, Benoît Crouzy, Katharina Maria Edmaier

We propose a minimal model for the response of seedlings to pullout constraints. Central to our approach is the idea of capturing not only average mechanical properties but also the stochastic component of the uprooting process. Our model accounts on one h ...

To What Extent Do Food Preferences Explain the Trophic Position of Heterotrophic and Mixotrophic Microbial Consumers in a Sphagnum Peatland?

Edward Mitchell, Vincent Eric Jules Jassey, Caroline Meyer

Although microorganisms are the primary drivers of biogeochemical cycles, the structure and functioning of microbial food webs are poorly studied. This is the case in Sphagnum peatlands, where microbial communities play a key role in the global carbon cycl ...
