Emerging predictable features of replicated biological invasion fronts

Andrea Rinaldo, Andrea Giometto, Florian Altermatt, Francesco Carrara

Biological dispersal shapes species' distribution and affects their coexistence. The spread of organisms governs the dynamics of invasive species, the spread of pathogens, and the shifts in species ranges due to climate or environmental change. Despite its ...

Fast seeding of NTMs by sawtooth crashes in TCV and their preemption using ECRH

Olivier Sauter, Basil Duval, Timothy Goodman, Jonathan Graves, Duccio Testa, Holger Reimerdes, Antoine Pochelon

Many tokamaks have observed that sawteeth of sufficient duration may trigger neoclassical tearing modes (NTMs) that lead to plasma performance degradation. In this paper, TCV's ability to accurately control the period of individual sawteeth is exploited, u ...

Hydrology as a driver of biodiversity: Controls on carrying capacity, niche formation, and dispersal

Andrea Rinaldo

A synthesis is presented highlighting the importance of hydrologic variables and dynamics to biodiversity patterns. The focus of this paper is the key hydrologic controls crucial towards quantifying the impacts of climate changes on the distribution of spe ...

Modelling the effect of size on the aerial dispersal of microorganisms

Isabelle Bey, Symeon Koumoutsaris

Aim We investigate the long-standing question of whether the small size of microbes allows most microbial species to colonize all suitable sites around the globe or whether their ranges are limited by opportunities for dispersal. In this study we use a mod ...

Dendritic connectivity controls biodiversity patterns in experimental metacommunities

Andrea Rinaldo, Florian Altermatt, Francesco Carrara

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 ...

Early detection, warnings, weak signals and seeds of change: A turbulent domain of futures studies

Pierre Rossel

This paper marks a milestone in a six year research cycle on weak signal analysis and early detection issues in futures studies. While providing a broad view and discussing a variety of contributions on this topic, the aim of this article is to offer a mor ...
