Coupled carbon and nitrogen cycling regulates the cnidarian–algal symbiosis

Anders Meibom, Stéphane Laurent Escrig, Nils Rädecker

Efficient nutrient recycling underpins the ecological success of cnidarian-algal symbioses in oligotrophic waters. In these symbioses, nitrogen limitation restricts the growth of algal endosymbionts in hospite and stimulates their release of photosynthates ...

CHARACTERIZING THE RESILIENCE AND ADAPTATION OF BIOFILM COMMUNITIES TO CLIMATE CHANGE IN GLACIER-FED STREAMS

Tom Ian Battin, Hannes Markus Peter, Grégoire Marie Octave Edouard Michoud, Nicola Deluigi, David Touchette, Martina Gonzalez Mateu, Florian Baier

Biofilms conform the dominant microbial lifestyle in alpine streams where they are major contributors to carbon and nutrient cycling. However, relatively little is known about their adaptive capacity to climate change as water temperature rises and hydrolo ...

Hydromorphological assessment of sediment augmentation measures in gravel-bed rivers

Christian Mörtl

In the riverine environment, the riverscape, sediment and flow regime are essential drivers for natural habitat dynamics. Today, most water courses in Europe are regulated, and their natural dynamics are impaired. Flood releases coupled with the artificial ...

Exploration of socio-ecological continuity project in great Geneva, toward a convergence of the territorial project of biodiversity and ecological continuities

Flore Jeanne Marie Andrea Guichot, Marine Françoise Jeannine Villaret

A territorial project impelling biodiversity and socio-ecological transitions implies its renewal. The recognition of the landscape as a support of biodiversity led to the establishment of the tool of ecological continuities (ECs) within territorial planni ...

The Land-Water-Energy Nexus of Ruzizi River Dams (Lake Kivu Outflow, African Great Lakes Region): Status, Challenges, and Perspectives

Alfred Johny Wüest

Hydroelectric power (HP) represents the main source of electricity in Africa, including the Democratic Republic of Congo. The demand for new dam construction is high, and major projects are currently progressing through planning and implementation stages. ...

From the Heroic Age to today: What diatoms from Shackleton's Nimrod expedition can tell us about the ecological trajectory of Antarctic ponds

Tyler Joe Kohler

Biological invasion and environmental change pose major threats to ecosystems. While long-term ecological change is commonly evaluated through sediment cores in lakes, it is generally not feasible for smaller ponds, and spatial resolution is limited. Here, ...

Reference tracking stochastic model predictive control over unreliable channels and bounded control actions

Colin Neil Jones

A stochastic model predictive control framework over unreliable Bernoulli communication channels, in the presence of unbounded process noise and under bounded control inputs, is presented for tracking a reference signal. The data losses in the control chan ...

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 ...

Resilience and agency in mature sustainability transitions. Theoretical conceptualisation and empirical analysis of actor- & system-level dynamics in sociotechnical energy systems

In Switzerland, Germany and Austria, as in many European countries, the transition of the energy sector towards more sustainability is a long-term transition process, unfolding since decades. It however only reached the regime level in recent years and the ...

Robust control of constrained systems given an information structure

Maryam Kamgarpour, Luca Furieri

We study finite horizon optimal control where the controller is subject to sensor-information constraints, that is, each input has access to a fixed subset of states at all times. In particular, we consider linear systems affected by exogenous disturbances ...
