Effects of Colonization Asymmetries on Metapopulation Persistence

Olivier Lévêque, Séverine Vuilleumier Varisco

Ocean currents, prevailing winds, and the hierarchical structures of river networks are known to create asymmetries in re-colonization between habitat patches. The impacts of such asymmetries on metapopulation persistence are seldom considered, especially ...

A review of habitat thresholds for dead wood: a baseline for management recommendations in European forests

In contemporary forest management, also of commercial forests, threshold values are widely used for consideration of biodiversity conservation. Here, we present various aspects of dead-wood threshold values. We review published and unpublished dead-wood th ...

Is There a Size Limit for Cosmopolitan Distribution in Free-Living Microorganisms? A Biogeographical Analysis of Testate Amoebae from Polar Areas

Jiangyan Yang

A long-standing debate in microbial ecology is the extent to which free-living microorganisms exhibit cosmopolitan distributions. We use a comparison of testate amoebae communities in cold "polar" locations (Arctic, Antarctic, and Tibet) to investigate how ...

Synergie de modélisations physique et numérique pour le développement d’atténuateurs de vagues d’un convoi fluvial / Synergy between physical and numerical modeling used for the development of ship waves attenuator

Robin Amacher, Théodora Cohen Liechti

Le batillage résulte du déferlement des vagues générées par le passage d’une embarcation. Les effets qui en résultent sur le milieu aquatique sont l’érosion des berges et la destruction des habitats. Sur le canton de Genève, une grande partie des déchets m ...

Molecular phylogeny of euglyphid testate amoebae (Cercozoa: Euglyphida) suggests transitions between marine supralittoral and freshwater/terrestrial environments are infrequent

Edward Mitchell, Enrique Lara, Thierry Jean Heger

Marine and freshwater ecosystems are fundamentally different regarding many biotic and abiotic parameters. The physiological adaptations required for an organism to pass the salinity barrier are considerable. Many eukaryotic lineages are restricted to eith ...

Morphogenèse de la ville contemporaine

Jong-Jin Park

Unstable growth, unlimited urban sprawl, and multiple fragmentations are contemporary urban phenomena requiring new investigations and interpretations of the physical impact of form on today's cities. The city as a living organism with an evolving structur ...

Tropical forest conservation: attitudes and preferences

Andrea Baranzini, Anne-Kathrin Faust

This paper applies contingent valuation to assess public awareness of tropical deforestation; to investigate the willingness to pay (WTP) to conserve tropical forests; and to determine the impact of the payment vehicle on the stated willingness to pay. Abo ...

Conservation priority of Italian Alpine habitats: a floristic approach based on potential distribution of vascular plant species

Luca Bragazza

In the European Union, the Directive 92/43/EEC defines a number of species and habitats of community interest that are worthy to be preserved because in danger to disappear or because they are representative of the different European bio-geographical regio ...

On neutral metacommunity patterns of river basins at different scales of aggregation

Andrea Rinaldo, Enrico Bertuzzo

Neutral metacommunity models for spatial biodiversity patterns are implemented on river networks acting as ecological corridors at different resolution. Coarse-graining elevation fields (under the constraint of preserving the basin mean elevation) produce ...

Locally-Resolved Study of Degradation in a SOFC Repeat- Element

Daniel Favrat, Jan Van Herle, Stefan Diethelm, Zacharie Wuillemin, Arata Nakajo, Andres Müller

The locally-resolved degradation behavior was studied during 1900 hours in an SOFC repeat-element. In-situ measurements of local electrochemical performance were made on 18 locations over a segmented anode-supported cell. The evolution of local current den ...
