High summer temperatures amplify functional differences between coral‐ and algae‐dominated reef communities

Nils Rädecker

Shifts from coral to algal dominance are expected to increase in tropical coral reefs as a result of anthropogenic disturbances. The consequences for key ecosystem functions such as primary productivity, calcification, and nutrient recycling are poorly und ...

Measured greenhouse gas budgets challenge emission savings from palm-oil biodiesel

Thomas Guillaume

The potential of palm-oil biofuels to reduce greenhouse gas (GHG) emissions compared with fossil fuels is increasingly questioned. So far, no measurement-based GHG budgets were available, and plantation age was ignored in Life Cycle Analyses (LCA). Here, w ...

Responses of plant leaf economic and hydraulic traits mediate the effects of early- and late-season drought on grassland productivity

Alexandre Buttler, Pierre Rémi Mariotte, Constant Signarbieux, Amarante Vitra

Drought can occur at different times during the grassland growing season, likely having contrasting effects on forage production when happening early or later in the season. However, knowledge about the interacting effects of the timing of drought and the ...

Bioethanol production from palm wood using Trichoderma reesei and Kluveromyces marxianus

Edgard Gnansounou

In the present work, palm wood was pretreated using hydrothermal technique in conjunction with chemical method for removal of lignin. Pretreated palm wood was subjected to hydrolysis using Trichoderma reesei MTCC 4876. Subsequently bioethanol was produced ...

Subordinate plant species moderate drought effects on earthworm communities in grasslands

Alexandre Buttler, Claire Guenat, Pierre Rémi Mariotte

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 ...

Harvesting of Chlorella sorokiniana by co-culture with the filamentous fungus Isaria fumosorosea: A potential sustainable feedstock for hydrothermal gasification

Christof Holliger, Jean-Paul Schwitzguebel, Eduardo Pereira Gomes, Stephen Mackay

Despite recent advances in down-stream processing, production of microalgae remains substantially limited because of economical reasons. Harvesting and dewatering are the most energy-intensive processing steps in their production and contribute 20–30% of t ...

Process Integration of Lignocellulosic Biomass Pre-treatment in the Thermo-Chemical Production of F-T Fuels. Centralised Versus Decentralised Scenarios

François Maréchal, Emanuela Peduzzi

The purpose of this study is to evaluate, in terms of process integration, the centralised and decentralised pre-treatment of lignocellulosic biomass for its thermo-chemical conversion into liquid fuels through gasification and Fischer-Tropsch (F-T) synthe ...

Subordinate plant species enhance community resistance against drought in semi-natural grasslands

Alexandre Buttler, Pierre Rémi Mariotte, Charlotte Vandenberghe

According to the insurance hypothesis, more diverse plant communities are more likely to be resistant to drought. Whilst many experiments have been carried out to determine the effects of plant diversity on plant community insurance, the results are still ...

Optimal process design for the polygeneration of SNG, power and heat by hydrothermal gasification of waste biomass: Process optimisation for selected substrates

François Maréchal, Frédéric Vogel, Martin Gassner

Based on a previously developed thermo-economic process model, this paper presents a detailed design study for the polygeneration of Synthetic Natural Gas (SNG), power and heat by catalytic hydrothermal gasification of biomass and biomass wastes in supercr ...

Competitive advantage of Rumex obtusifolius L. might increase in intensively managed temperate grasslands under drier climate

Constant Signarbieux

Climate models predict decreasing amounts of precipitation for future summers in Switzerland. Since grasslands cover about one quarter of the area, severe consequences might be expected for Swiss agriculture, ranging from loss of grassland productivity to ...

GIS-based approach for defining bioenergy facilities location: A case study in Northern Spain based on marginal delivery costs and resources competition between facilities

Edgard Gnansounou, Luis Alberto Panichelli

This paper presents a GIS-based decision support system for selecting least-cost bioenergy locations when there is a significant variability in biomass farmgate price and when more than one bioenergy plant with a fixed capacity has to be placed in the regi ...

Can microbial growth yield be estimated using simple thermodynamic analogies to technical processes?

Urs von Stockar

In view of the prime importance of the biomass yield in microbial growth for research, for environmental and for industrial applications some thermodynamic concepts are reviewed that were developed over the years in order to understand the large variations ...

Thermodynamics of microbial growth and metabolism: An analysis of the current situation

Urs von Stockar, Ian William Marison

This paper attempts to review in how far thermodn. anal. can be used to understand and predict the performance of microorganisms with respect to growth and bioproduct synthesis. In the first part, a simple thermodn. model of microbial growth is developed w ...
