Intervention strategies to mitigate hydropeaking: Two case studies from Switzerland

Water retention in reservoirs and concentrated turbine operations allow electricity to be produced on demand. Sudden opening and closing of the turbines can produce highly unsteady flow conditions in the river downstream of the tailrace channel, the so-cal ...

Are viruses important in the plankton of highly turbid glacier-fed lakes?

Hannes Markus Peter

Viruses are ubiquitous in aquatic ecosystems where they significantly contribute to microbial mortality. In glacier-fed turbid lakes, however, viruses not only encounter low host abundances, but also a high number of suspended mineral particles introduced ...

Chapter 4.2.1 : The Microbial Ecology of Benthic Environments

Tom Ian Battin

Within the benthic realm life carpets the sedimentary surface of all aquatic ecosystems including the oceans, lakes, rivers and streams. Microorganisms of all types, bacteria, archaea and eukaryotes, inhabit these environments and through their metabolic a ...

Oxygen depletion in stratified lakes - why shallow and deep lakes react differently

Alfred Johny Wüest, Robert Vincent Schwefel

Oxygen is the most important element in natural waters for any higher aquatic life, such as fish. As with humans, almost all members of aquatic ecosystems need oxygen to breathe. Building on this, treatment of drinking water is easier for oxic than for ano ...

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

Janine Rüegg

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 ...

Defining Ecological Strategies in Neuroprosthetics

Grégoire Courtine, Jocelyne Bloch

Neurological disorders disrupt the equilibrium within the brain and spinal cord ecosystems. Ecology reuses, recycles, and reduces to help maintain the balance across ecosystems. Likewise, neuroprosthetics can help the brain help itself with ecoprosthetic d ...

Generalized receptor law governs phototaxis in the phytoplankton Euglena gracilis

Andrea Rinaldo, Andrea Giometto, Amos Maritan, Florian Altermatt

Phototaxis, the process through which motile organisms direct their swimming toward or away from light, is implicated in key ecological phenomena (including algal blooms and diel vertical migration) that shape the distribution, diversity, and productivity ...

Mitigation measures for fish habitat improvement in Alpine rivers affected by hydropower operations

Anton Schleiss, Martin Peter Bieri, Émilie Person, Armin Julius Peter

In mountainous areas, high-head-storage hydropower plants produce peak load energy. The resulting unsteady water release to rivers, called hydropeaking, alters the natural flow regime. Mitigating the adverse impacts of hydropeaking on aquatic ecosystems ha ...

No evidence of aquatic priming effects in hyporheic zone microcosms

Tom Ian Battin

The priming effect refers to quantitative changes in microbial decomposition of recalcitrant organic matter upon addition of labile organic matter and is a phenomenon that mainly has been reported and debated in soil science. Recently, priming effects have ...

The effect of abrupt climatic warming on biogeochemical cycling and N2O emissions in a terrestrial ecosystem

Jed Oliver Kaplan, Mirjam Pfeiffer

The large, rapid increase in atmospheric N2O concentrations that occurred concurrent with the abrupt warming at the end of the Last Glacial period might have been the result of a reorganization in global biogeochemical cycles. To explore the sensitivity of ...
