Spatiotemporal Dynamics of Flow and Hydrochemistry in Drainage Networks

Despite their high ecological value, non-perennial streams have received less attention than their perennial counterparts. This doctoral thesis addresses this disparity by advancing knowledge on the dynamics of the drainage density and hydrologic processes ...

Genomics and conservation: Guidance from training to analyses and applications

Annie Sandrine Guillaume

Environmental change is intensifying the biodiversity crisis and threatening species across the tree of life. Conservation genomics can help inform conservation actions and slow biodiversity loss. However, more training, appropriate use of novel genomic me ...

Power exhaust by core radiation at COMPASS tokamak

Olivier Claude Martin Février, Davide Mancini

Substantial power dissipation in the edge plasma is required for the safe operation of ITER and next-step fusion reactors, otherwise unmitigated heat fluxes at the divertor plasma-facing components (PFCs) would easily exceed their material limits. Traditio ...

Counting People by Estimating People Flows

Pascal Fua, Mathieu Salzmann, Weizhe Liu

Modern methods for counting people in crowded scenes rely on deep networks to estimate people densities in individual images. As such, only very few take advantage of temporal consistency in video sequences, and those that do only impose weak smoothness co ...

Seascape genomics to empower coral reef conservation strategies

Oliver Michele Selmoni

The future of coral reefs is under threat since anomalous heat waves are causing the death of reef building corals around the world. This phenomenon, known as "coral bleaching", has already resulted in widespread loss of coral over the past 30 years. Witho ...

“HOUSING Frankfurt Wien Stockholm”: Exhibition of 1920s–1930s Housing Initiatives

Chiara Monterumisi, Alessandro Porotto

Frankfurt, Vienna and Stockholm: three European cities which played a fundamental role in the housing policies implemented during the inter-war period. The research projects and teaching activity carried out at the EPFL in the Laboratory of Construction an ...

Impacts of thermal mismatches on chytrid fungus Batrachochytrium dendrobatidis prevalence are moderated by life stage, body size, elevation and latitude

Suzanne Marie Young

Global climate change is increasing the frequency of unpredictable weather conditions; however, it remains unclear how species-level and geographic factors, including body size and latitude, moderate impacts of unusually warm or cool temperatures on diseas ...

Fitting Markovian binary trees using global and individual demographic data

Sophie Myriam Hautphenne, Katharine Felicity Turner

We consider a class of continuous-time branching processes called Markovian binary trees (MBTs), in which the individuals lifetime and reproduction epochs are modelled using a transient Markovian arrival process (TMAP). We develop methods for estimating th ...

Inventaire des coléoptères saproxyliques de treize forêts du canton de Vaud

Rita Bütler Sauvain, Gaspard Braulin

In 2017, surveys of saproxylic beetles (dependent on dead wood) were conducted in thirteen forests in the canton of Vaud (Switzerland), including several forest reserves. Interception traps were used to catch a total of 298 species of Coleoptera, including ...

A WebGIS platform for the monitoring of Farm Animal Genetic Resources (GENMON)

Stéphane Joost, Giona Matasci, Ivo Widmer, Solange Catherine Gaillard

Background In 2007, the Food and Agriculture Organization of the United Nations (FAO) initiated the Global plan of action for Farm Animal Genetic Resources (FAnGR). The main goal of this plan is to reduce further loss of genetic diversity in farm animals, ...

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 ...

Improving slash-and-burn agriculture in Central Menabe, Madagascar

Justine Marie Gay des Combes

Slash-and-burn agriculture is considered as an important driver of deforestation in the tropics. In Madagascar, a biodiversity hotspot, this type of agriculture particularly threatens the tropical forest cover. On the south-western coast of the island, in ...

New lakes in deglaciating high-mountain regions – opportunities and risks

Anton Schleiss

In connection with the ongoing disappearance of glaciers in cold mountains, a great number of new lakes come into existence. The sites and approximate formation time of such potential new lakes can be realistically modelled. This provides an important know ...

Mitochondrial DNA Analyses Indicate High Diversity, Expansive Population Growth and High Genetic Connectivity of Vent Copepods (Dirivultidae) across Different Oceans

Stefan Jean Laurent

Communities in spatially fragmented deep-sea hydrothermal vents rich in polymetallic sulfides could soon face major disturbance events due to deep-sea mineral mining, such that unraveling patterns of gene flow between hydrothermal vent populations will be ...

Landscape-scale simulation experiments test Romanian and Swiss management guidelines for mountain pasture-woodland habitat diversity

Alexandre Buttler, François Gillet, Alexander Ludwig Johannes Peringer, Ioana Stoicescu

Distinct guidelines have been proposed in Romania and Switzerland for the management of pasture woodlands that either focused on the regulation of grazing pressure (Romanian production perspective) or overall tree cover (Swiss conservation perspective). Ho ...

Reactivation of Klingnau reservoir sidearm: Numerical simulation of sediment release downstream

Anton Schleiss, Giovanni De Cesare, Azin Amini, Philippe Heller

The Klingnau reservoir, situated in north Switzerland, suffers from sedimentation in its left enlargement. The dam is placed in the Aare River about 1 km upstream of its confluence with the Rhine. Due to natural conservation and flood protection reasons, i ...

Exact Ground States of Frustrated Spin-1 Ising-Heisenberg and Heisenberg Ladders in a Magnetic Field

Frédéric Mila, Frédéric Alexis Michaud

Ground states of the frustrated spin-1 Ising-Heisenberg two-leg ladder with Heisenberg intra-rung coupling and only Ising interaction along legs and diagonals are rigorously found by taking advantage of local conservation of the total spin on each rung. Th ...

The Hourglass and the Early Conservation Models-Co-Existing Patterns of Developmental Constraints in Vertebrates

Pawel Lichocki

Developmental constraints have been postulated to limit the space of feasible phenotypes and thus shape animal evolution. These constraints have been suggested to be the strongest during either early or mid-embryogenesis, which corresponds to the early con ...

Optimal use of conservation and accessibility filters in microRNA target prediction

Jiri Vanicek, Ray Marcel Marin Florez

It is generally accepted that filtering microRNA (miRNA) target predictions by conservation or by accessibility can reduce the false discovery rate. However, these two strategies are usually not exploited in a combined and flexible manner. Here, we introdu ...
