Ammonia exposure promotes algal biomass in an ombrotrophic peatland

Nitrogen pollution affects many peatlands with consequences for their biodiversity and ecosystem function. Microorganisms control nutrient cycling and constitute most of the biodiversity of peatlands but their response to nitrogen is poorly characterised a ...

Biotic plant-soil feedbacks across temporal scales

Pierre Rémi Mariotte

Plant effects on soil biota can result in feedbacks affecting plant performance, with consequences for plant community and ecosystem dynamics on short and long time-scales. In addition, the strength and direction of plant-soil feedbacks depend on tempor ...

Seasonal patterns of testate amoeba diversity, community structure and species-environment relationships in four Sphagnum-dominated peatlands along a 1300 m altitudinal gradient in Switzerland

Alexandre Buttler, Edward Mitchell, Luca Bragazza, Vincent Eric Jules Jassey, Mariusz Lamentowicz

Altitudinal gradients are useful to study the potential effects of climate change on ecosystems. Historically, studies on elevation gradients have primarily focused on macro-organisms and ecosystem processes, while microorganisms have been mostly ignored d ...

Seawater intrusion processes, investigation and management: Recent advances and future challenges

David Andrew Barry

Seawater intrusion (SI) is a global issue, exacerbated by increasing demands for freshwater in coastal zones and predisposed to the influences of rising sea levels and changing climates. This review presents the state of knowledge in SI research, compares ...

Snow cover manipulation effects on microbial community structure and soil chemistry in a mountain bog

Alexandre Buttler, Luca Bragazza, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek

Alterations in snow cover driven by climate change may impact ecosystem functioning, including biogeochemistry and soil (microbial) processes. We elucidated the effects of snow cover manipulation (SCM) on above-and belowground processes in a temperate peat ...

Spatio-temporal heterogeneity of riparian soil morphology in a restored floodplain

Claire Guenat, Géraldine Michèle Bullinger, Edward Mitchell, Bertrand Fournier

Floodplains have been intensively altered in industrialized countries, but are now increasingly being restored. It is therefore important to assess the effect of these restoration projects on the aquatic and terrestrial components of ecosystems. However, d ...

3-D PSF fitting for fluorescence microscopy: implementation and localization application

Michaël Unser, Daniel Sage, François Aguet, Hagay Kirshner

Localization microscopy relies on computationally efficient Gaussian approximations of the point spread function for the calculation of fluorophore positions. Theoretical predictions show that under specific experimental conditions, localization accuracy i ...

Modelling Time Series Extremes

Anthony Christopher Davison, Valérie Chavez

The need to model rare events of univariate time series has led to many recent advances in theory and methods. In this paper, we review telegraphically the literature on extremes of dependent time series and list some remaining challenges. ...

How do plant community ecologists consider the complementarity of observational, experimental and theoretical approaches ?

Alexandre Buttler, Pierre Rémi Mariotte, François Gillet, Thomas Spiegelberger, Aurélie Thébault

Background and aims -- A panoply of methods are used by ecologists for studies at the plant community level. While early studies were mainly descriptive, more manipulative experiments are now being undertaken because they provide a more functional approach ...

Maximum entropy production, carbon assimilation, and the spatial organization of vegetation in river basins

Andrea Rinaldo

The spatial organization of functional vegetation types in river basins is a major determinant of their runoff production, biodiversity, and ecosystem services. The optimization of different objective functions has been suggested to control the adaptive be ...
