Wavelength conversion and temporal compression of a pulse train using a dispersion oscillating fiber

2014

International audience; We demonstrate the generation of a picosecond pulse train taking advantage of the cross gain occurring in a dispersion oscillating fibre. The resulting frequency-converted signal is detuned by more than 20 nm from the pump and can be temporally compressed by a factor 2 compared to the input sinusoidal pump wave.

Caractérisation de la distribution spatiale des communautés microbiennes du sol et de ses déterminants à l’échelle du paysage

2014

International audience; Depuis plusieurs années, des approches biogéographiques ont été développées pour mieux caractériser la distribution spatiale des communautés microbiennes du sol, comprendre les processus écologiques mis en œuvre et identifier les filtres environnementaux déterminant leur diversité et leur structure. Ces approches ont été mises en œuvre à différentes échelles spatiales allant de celle de la parcelle agricole à celle d’un territoire et d’un continent. Elles ont permis de mettre en évidence que les communautés microbiennes du sol sont distribuées suivant des patterns biogéographiques non aléatoire et que ces dernières sont soumises à des processus déterministes (sélecti…

Observation of the suppression of the flux of cosmic rays above 4x10^19eV

2008

The energy spectrum of cosmic rays above 2.5 × 10¹⁸ eV, derived from 20,000 events recorded at the Pierre Auger Observatory, is described. The spectral index γ of the particle flux, J ∝ E-γ, at energies between 4 × 10¹⁸ eV and 4 × 10¹⁹ eV is 2.69 ± 0.02(stat) ± 0.06(syst), steepening to 4.2 ± 0.4(stat) ± 0.06(syst) at higher energies. The hypothesis of a single power law is rejected with a significance greater than 6 standard deviations. The data are consistent with the prediction by Greisen and by Zatsepin and Kuz'min.

Spatial processes driving soil microbial community assembly on a wide scale

2012

International audience; Soil houses a huge biodiversity involved in ecological services through microbial community assembly. However, processes driving soil microbial community assembly are still scarcely understood, particularly the relative importance of environmental heterogeneity regarding to dispersal limitations. This can be achieved through studying the determinism of taxa-area relationship (TAR, how community composition change with geographic distance), a fundamental relationship in ecology. Here, a biogeographical approach was applied on a wide scale to evaluate TAR for soil bacterial and fungal communities and to partition their spatial variations into environmental heterogeneit…

Designing ‘trait-based null model’ approaches to investigate community assembly mechanisms

2014

SPEEAECOLDURGEAPSIéquipe CAPA; During the last decade, many studies have addressed the signature of community assembly processes by assessing the deviation of a functional diversity pattern from that expected in null communities, using a randomization algorithm. The basic principle has been to compare the functional structure of a ‘local community’ with a set of randomly generated communities from a ‘regional species pool’. Specifically, it allows assessing the extent to which species constituting a community are functionally more or less similar than expected under the assumption of a random assembly, thus revealing the influence of assembly processes such as competition or environmental a…
