Assessment of abundance and community composition of benthic macroinvertebrates: recommendations for improved sampling, fixation and extraction of oligochaetes

Benoît Jean Dominique Ferrari, Régis Lionel Vivien

For several decades, the abundance and community structure of benthic macroinvertebrates have been studied to assess the biological quality of aquatic ecosystems. Procedures aiming at studying the whole of macroinvertebrate communities were mainly designed ...

Plant responses to rising vapor pressure deficit

Charlotte Grossiord

Recent decades have been characterized by increasing temperatures worldwide, resulting in an exponential climb in vapor pressure deficit (VPD). VPD has been identified as an increasingly important driver of plant functioning in terrestrial biomes including ...

Dissimilarities in polyphosphate accumulation between Shewanella loihica and the model bacterium Shewanella oneidensis

Julien Maillard

Polyphosphate plays an important role in the physiological adaptation of bacteria during growth and development, as well as in their response to nutritional and environmental stresses. Moreover, polyphosphate accumulation is of environmental relevance and ...

Catchment land cover influences macroinvertebrate food-web structure and energy flow pathways in mountain streams

Tom Ian Battin, Christopher Robinson

Understanding how different food resources sustain stream food webs is fundamental towards increasing our knowledge on trophic structure and energy flow pathways in fluvial ecosystems. 2. Food webs in small mountain streams are sustained by autochthonou ...

Colloid transport and distribution in the hyporheic zone

David Andrew Barry

Colloids moving from the stream into the hyporheic zone may have a negative impact on aquatic ecosystems as they are potential contaminants or carriers of contaminants. Moreover, retained colloids in the hyporheic zone could not only reduce the exchange fl ...

Benchmarking protocols for the metagenomic analysis of stream biofilm viromes

Tom Ian Battin, Hannes Markus Peter, Massimo Bourquin, Jade Brandani, Meriem Bekliz

Viruses drive microbial diversity, function and evolution and influence important biogeochemical cycles in aquatic ecosystems. Despite their relevance, we currently lack an understanding of their potential impacts on stream biofilm structure and function. ...

Coopetition and Ecosystems: Case of Amazon.com

Alain Wegmann, Arash Golnam, Gorica Tapandjieva Sekulovska

Business and innovation ecosystems involve complex interdependencies among various actors. The concept of ecosystem is useful for analyzing strategies in which competitors are also considered as complementary partners. To make this explicit, we use SEAM – ...

Scaling as a key conceptual tool for the interpretation of empirical and experimental patterns in ecology and biology

Silvia Zaoli

This thesis is concerned with regular patterns found in ecology and biology, their linkages and the statistical description of their fluctuations around average trends. Among such patterns, often conforming to power laws, well-known examples include the Sp ...

Effect of drought on grasslands: Soil core reciprocal transplantation experiment

Géraldine Delphine Mercier

Grassland ecosystems are challenged to meet the growing demand for ecosystem services and providing human goods. The expected increase in extreme climatic events will cause significant constraints on grassland systems that are particularly sensitive to dro ...

Ecohydrological interfaces as hotspots of ecosystem processes

Tom Ian Battin

The movement of water, matter, organisms, and energy can be altered substantially at ecohydrological interfaces, the dynamic transition zones that often develop within ecotones or boundaries between adjacent ecosystems. Interdisciplinary research over the ...
