Effects of Sphagnum Leachate on Competitive Sphagnum Microbiome Depend on Species and Time

Alexandre Buttler, Luca Bragazza, Constant Signarbieux, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek, Samuel Thomas Gabriel Hamard

Plant specialized metabolites play an important role in soil carbon (C) and nutrient fluxes. Through anti-microbial effects, they can modulate microbial assemblages and associated microbial-driven processes, such as nutrient cycling, so to positively or ne ...

Catchment land cover influences macroinvertebrate food-web structure and energy flow pathways in mountain streams

Tom Ian Battin, Christopher Robinson

Understanding how different food resources sustain stream food webs is fundamental towards increasing our knowledge on trophic structure and energy flow pathways in fluvial ecosystems. 2. Food webs in small mountain streams are sustained by autochthonou ...

A generalized definition of reactivity for ecological systems and the problem of transient species dynamics

Andrea Rinaldo, Lorenzo Mari, Marino Gatto

Perturbations to an ecosystem's steady state can trigger transient responses of great ecological relevance. Asymptotic stability determines whether a generic perturbation will fade out in the long run, but falls short of characterizing the dynamics imme ...

Stability analysis of ecomorphodynamic equations

Paolo Perona, Benoît Crouzy

In order to shed light on the influence of riverbed vegetation on river morphodynamics, we perform a linear stability analysis on a minimal model of vegetation dynamics coupled with classical one- and two-dimensional Saint-Venant-Exner equations of morphod ...

The influence of competition from herbaceous vegetation and shade on simulated browsing tolerance of coniferous and deciduous saplings

Alexandre Buttler, Charlotte Vandenberghe, François Frelechoux

The ability of saplings to tolerate browsing (i.e. the ability to persist with reduced biomass and to compensate for biomass loss) is influenced by the level of stress and their growth strategies. Ultimately, insight into species-specific responses of sapl ...
