The role of Encapsulants in the long-term performance of advanced Crystalline Silicon Glass-Glass PV modules

The adoption of crystalline silicon (c-Si) PV modules based on glass-glass (G-G) structures is gaining momentum because of the possibility to manufacture bifacial panels, collecting light from the rear side. Despite not being an optimal material, Ethylene ...

Both diversity and functional composition affect productivity and water use efficiency in experimental temperate grasslands

Charlotte Grossiord, Margaux Clara Lou Didion-Gency

Many experiments have shown that biodiversity promotes ecosystem functioning and stability and that this relationship varies with resource availability. However, we still have a poor understanding of the underlying physiological and ecological mechanisms d ...

Adaptation of Human Enterovirus to Warm Environments Leads to Resistance against Chlorine Disinfection

Tamar Kohn, Anna Carratala Ripolles, Virginie Bachmann, Timothy R. Julian

Sunlight, temperature, and microbial grazing are among the environmental factors promoting the inactivation of viral pathogens in surface waters. Globally, these factors vary across time and space. The persistence of viral pathogens, and ultimately their e ...

Responses of permanent grasslands to drought during the plant growing season: combining agronomic, functional and ecophysiological approaches

Amarante Vitra

Extreme summer drought events are predicted to increase in intensity and frequency within the current century. The resulting water scarcity could dramatically impact human activities related to agriculture, due to the strong relationship between precipitat ...

Carbon neutral expansion of oil palm plantations in the Neotropics

Alexandre Buttler, Thomas Guillaume, Juan Carlos Quezada Rivera

Alternatives to ecologically devastating deforestation land use change trajectories are needed to reduce the carbon footprint of oil palm (OP) plantations in the tropics. Although various land use change options have been proposed, so far, there are no emp ...

Contrasting processes drive alpha and beta taxonomic, functional and phylogenetic diversity of orthopteran communities in grasslands

François Gillet, Bertrand Fournier

Taxonomic, functional and phylogenetic diversities can respond differently to biotic and abiotic filters. However, biodiversity management tends to focus on a single index, generally taxonomic diversity, assuming a strong positive correlation among biodive ...

Disturbance-grazer-vegetation interactions maintain habitat diversity in mountain pasture-woodlands

Alexandre Buttler, François Gillet, Alexander Ludwig Johannes Peringer

Low-intensity livestock grazing is a widespread management tool in order to maintain habitat diversity in mountain pasture-woodlands for nature conservation purposes. Historical photographs indicate that forest disturbance significantly contributed to fore ...

Detecting animals in African Savanna with UAVs and the crowds

Stéphane Joost, Devis Tuia

Unmanned aerial vehicles (UAVs) offer new opportunities for wildlife monitoring, with several advantages over traditional field-based methods. They have readily been used to count birds, marine mammals and large herbivores in different environments, tasks ...

Drought-induced shifts in plants traits, yields and nutritive value under realistic grazing and mowing managements in a mountain grassland

Alexandre Buttler, Constant Signarbieux, Thomas Spiegelberger, Claire Emilie Deléglise

Extreme drought events can dramatically impact grassland ecosystems, causing potential loss of forage production for livestock in temperate grasslands. However, knowledge of drought effects on forage production, nutritive value and plant community stabilit ...

Impact of management type and intensity on multiple facets of grassland biodiversity in the French Jura Mountains

François Gillet

Questions(1) Does grassland vegetation differ in its taxonomic, phylogenetic and functional alpha diversity between strictly grazed parcels (SGP) and mowed-and-grazed parcels (MGP)? (2) Do we observe differences in the responses of functional diversity (re ...
