Species conservation in the face of global environmental changes: surface-based modelling of geo-environmental data to identify vulnerable populations

Human activities are resulting in many land-use changes, particularly due to urbanisation and intensification of agricultural practices. Because of these changes, in addition to climate change, many species are facing habitat degradation. In order to avoid ...

Ecohydrological and Metacommunity Studies of Proliferative Kidney Disease Spread in Freshwater Salmonid Fish

Luca Carraro

Proliferative kidney disease (PKD) is a high-mortality pathology affecting freshwater salmonid populations in Europe and North America. Its causative agent, the myxozoan Tetracapsuloides bryosalmonae, has a complex life-cycle exploiting freshwater bryozoan ...

Persistence of butterfly populations in fragmented habitats along urban density gradients: motility helps

Stéphane Joost, Estelle Rochat, Ivo Widmer

In a simulation study of genotypes conducted over 100 generations for more than 1600 butterfly’s individuals, we evaluate how the increase of anthropogenic fragmentation and reduction of habitat size along urbanisation gradients (from 7% to 59% of impervio ...

Disentangling human tolerance and resistance against HIV

Jacques Fellay, Amalio Telenti, Paul Jack Mc Laren

In ecology, "disease tolerance" is defined as an evolutionary strategy of hosts against pathogens, characterized by reduced or absent pathogenesis despite high pathogen load. To our knowledge, tolerance has to date not been quantified and disentangled from ...

Complex Interaction of Dendritic Connectivity and Hierarchical Patch Size on Biodiversity in River-Like Landscapes

Andrea Rinaldo, Andrea Giometto, Francesco Carrara, Florian Altermatt

Habitat fragmentation and land use changes are causing major biodiversity losses. Connectivity of the landscape or environmental conditions alone can shape biodiversity patterns. In nature, however, local habitat characteristics are often intrinsically lin ...

Theoretical and Experimental Studies of Dendritic Metacommunities

Francesco Carrara

The present thesis deals with the understanding of the origins and the mechanisms of maintenance of biodiversity in natural landscapes, in particular by identifying key processes that define large-scale patterns of abundance and diversity. Biological commu ...

A case study on spatial and temporal hydraulic variability in an alpine gravel-bed stream based on the hydromorphological index of diversity

Anton Schleiss, Walter Gostner, Piotr Parasiewicz

Physical heterogeneity is a major topic in river sciences because it is known to be a key factor for ecological integrity. In this paper, we investigated the hydraulic enviroment in an alpine gravel-bed stream with an unaltered hydrological regime. The stu ...

Dendritic connectivity controls biodiversity patterns in experimental metacommunities

Andrea Rinaldo, Francesco Carrara, Florian Altermatt

Biological communities often occur in spatially structured habitats where connectivity directly affects dispersal and metacommunity processes. Recent theoretical work suggests that dispersal constrained by the connectivity of specific habitat structures, s ...

Mycobacterium tuberculosis persistence mutants identified by screening in isoniazid-treated mice

John McKinney, Neeraj Dhar

Tuberculosis (TB) is notoriously difficult to cure, requiring administration of multiple antibiotics for 6 mo or longer. Conventional anti-TB drugs inhibit biosynthetic processes involved in cell growth and division, such as DNA replication, RNA transcript ...
