Riparian wetland properties counter the effect of land-use change on soil carbon stocks after rainforest conversion to plantations

Thomas Guillaume

Progressive conversion of tropical rainforests to agricultural monocultures in South East Asia increasingly affects landscape types such as riparian areas. The impacts of conversions on soil organic matter (SOM) vary with changing landforms. However, this ...

The role of immune effectors in controlling Drosophila-microbes interactions

Alice Marra

All live beings are in constant interaction with microorganisms that may be beneficial, deleterious or commensal. Insects in particular live in close contact with microorganisms. This is especially true for species, like the fruit fly Drosophila melanogast ...

Increasing temperature and decreasing specific leaf area amplify centipede predation impact on Collembola

Mathieu Raymond Santonja

Collembola is an abundant group of soil organisms playing a major role on litter decomposition process and nutrient cycling in forest ecosystems. Habitat structure strongly influences Collembola assemblages as plant litter physical characteristics and quan ...

Tomography-based radiative characterisation of decomposing carbonaceous heat shield materials

Sophia Haussener, Pénélope Leyland, Nikhil Banerji

This work evaluates the changes in radiative properties of two decomposing carbonaceous porous materials, each composed of two semitransparent, homogeneous and isotropic phases. The understanding of the complex dependence of macroscopic optical behaviour o ...

Subordinate plants mitigate drought effects on soil ecosystem processes by stimulating fungi

Alexandre Buttler, Vincent Eric Jules Jassey, Pierre Rémi Mariotte, Bjorn Jozef Maria Robroek

The subordinate insurance hypothesis suggests that highly diverse communities contain greater numbers of subordinate species than less diverse communities. It has previously been reported that subordinate species can improve grassland productivity durin ...

Biotic and Abiotic Constraints on the Decomposition of Fagus sylvatica Leaf Litter Along an Altitudinal Gradient in Contrasting Land-Use Types

Alexandre Buttler, Konstantin Svetlozarov Gavazov, Robert Thomas Edmund Mills, Thomas Spiegelberger

Climate change can affect the process of carbon cycling and leaf litter decomposition in multiple ways, both directly and indirectly, though the strength and direction of this relationship is often context dependent. In this experiment, we followed decompo ...

Diminished soil functions occur under simulated climate change in a sup-alpine pasture, but heterotrophic temperature sensitivity indicates microbial resilience

Alexandre Buttler, Konstantin Svetlozarov Gavazov, Robert Thomas Edmund Mills, Thomas Spiegelberger

The pressure of climate change is disproportionately high in mountainous regions, and small changes may push ecosystem processes beyond sensitivity thresholds, creating new dynamics of carbon and nutrient cycling. Given that the rate of organic matter deco ...

Biogeochemical plant-soil microbe feedback in response to climate warming in peatlands

Alexandre Buttler, Luca Bragazza, Julien Parisod

Peatlands act as global sinks of atmospheric carbon (C) through the accumulation of organic matter(1), primarily made up of decay-resistant litter of peat mosses(2). However, climate warming has been shown to promote vascular plant growth in peatlands, esp ...

High nitrogen deposition alters the decomposition of bog plant litter and reduces carbon accumulation

Alexandre Buttler, Luca Bragazza

Bogs are globally important sinks of atmospheric carbon (C) due to the accumulation of partially decomposed litter that forms peat. Because bogs receive their nutrients from the atmosphere, the world-wide increase of nitrogen (N) deposition is expected to ...

Effects of Subordinate Plant Species in Plant and Soil Community Structure and Ecosystem Functioning

Pierre Rémi Mariotte

The relevance of biodiversity to human health is an increasing international political issue as it causes concern for ethical and aesthetic reasons, but also has a strong impact on ecosystem properties and ecological goods and services utilised by humanity ...

Litter- and ecosystem-driven decomposition under elevated CO2 and enhanced N deposition in a Sphagnum peatland

Alexandre Buttler, Luca Bragazza, Andy Siegenthaler

Peatlands represent massive global C pools and sinks. Carbon accumulation depends on the ratio between net primary production and decomposition, both of which can change under projected increases of atmospheric CO2 and N deposition. The decomposition of li ...

Tidal influence on BTEX biodegradation in sandy coastal aquifers

David Andrew Barry, Alessandro Brovelli, Clare Robinson

A numerical study was conducted to investigate the influence of tides on the fate of terrestrially-derived BTEX discharging through an unconfined aquifer to coastal waters. Previous studies have revealed that tide-induced seawater circulations create an ac ...

Modeling of thermo-physical properties for FRP composites under elevated and high temperatures

Thomas Keller, Till Vallée, Yu Bai

A decomposition model for resin in glass fiber-reinforced polymer composites (GFRP) under elevated and high temperature was derived from chemical kinetics. Kinetic parameters were determined by four different methods using thermal gravimetric data at diffe ...

Dynamic Texture Analysis and Synthesis using Tensor Decomposition

Sabine Süsstrunk, Luciano Sbaiz, Roberto Costantini

Dynamic textures are sequences of images showing temporal regularity, such as smoke, flames, flowing water, or moving grass. Despite being a multidimensional signal, existing models reshape the dynamic texture into a 2D signal for analysis. In this article ...
