Novel Mechanistic Insight into the Molecular Basis of Amyloid Polymorphism and Secondary Nucleation during Amyloid Formation

Giovanni Dietler, Hilal Lashuel, Annalisa Ansaloni, Jae Sun Jeong, Raffaele Mezzenga

The formation of amyloid β (Aβ) fibrils is crucial in initiating the cascade of pathological events that culminates in Alzheimer's disease. In this study, we investigated the mechanism of Aβ fibril formation from hydrodynamically well defined species under ...

The effect of crowding and confinement: a comparison of Yfh1 stability in different environments

Paolo De Los Rios

Crowding and confinement can affect protein stability, favouring the more compact species amongst the folded and unfolded conformations. An unbiased assessment of the relative efficacy of crowded and confined environments has been hampered so far by the pa ...

Toward the use of testate amoeba functional traits as indicator of floodplain restoration success

Edward Mitchell, Bertrand Fournier

Functional traits (FT) offer a new framework to understand the ecology of organisms and overcome taxonomic difficulties that currently limit the study of minute soil taxa. FT are likely to be selected by environmental filters and hence they may provide mor ...

An exactly solvable coarse-grained model for species diversity

Andrea Rinaldo, Samir Suweis, Amos Maritan

We present novel analytical results concerning ecosystem species diversity that stem from a proposed coarse-grained neutral model based on birth-death processes. The relevance of the problem lies in the urgency for understanding and synthesizing both theor ...

Routes to Novel Colloidal Gels

Francesco Varrato

The thesis describes how demixing of binary colloidal mixtures could be used to design new kinds of amorphous structures. We show that a rich phase behavior emerges, dependent on density (colloidal concentration) and composition (species relative populatio ...

Effects of Subordinate Plant Species in Plant and Soil Community Structure and Ecosystem Functioning

Pierre Rémi Mariotte

The relevance of biodiversity to human health is an increasing international political issue as it causes concern for ethical and aesthetic reasons, but also has a strong impact on ecosystem properties and ecological goods and services utilised by humanity ...

On species persistence-time distributions

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Samir Suweis, Amos Maritan

We present new theoretical and empirical results on the probability distributions of species persistence times in natural ecosystems. Persistence times, defined as the timespans occurring between species' colonization and local extinction in a given geogra ...

Hydrologic Drivers and Controls of Stream Ecological Processes

Serena Ceola

The temporal variability of streamflows is a key feature structuring and controlling ecological communities and ecosystem processes. The magnitude, frequency and predictability of streamflows, and thus of velocity and near-bed shear stress fields, control ...

Patterns of earthworm communities and species traits in relation to the perturbation gradient of a restored floodplain

Edward Mitchell, Renée-Claire Le Bayon, Bertrand Fournier

Little is known about the diversity and ecology of earthworms in flocdplains, as well as their response to natural and anthropic perturbations (e.g. floods, river channelisation, floodplain restoration). We characterised the patterns of earthworm communiti ...

Stable carbon and oxygen isotope compositions of extant crinoidal echinoderm skeletons

Anders Meibom, Jaroslaw Hubert Stolarski

The variability of delta C-13 and delta O-18 was determined within the columnal facet of individual ossicles, within different regions of skeletons and within bulk skeletons of extant stalked crinoids. Isotopic compositions of individual ossicles may vary ...
