Spatial and temporal patterns of denitrification in a riparian forest

G Pinay, L Roques, A Fabre - Journal of Applied Ecology, 1993 - JSTOR
1. This study estimated the importance of in situ denitrification in the nitrate buffering
capacities of a riparian forest. 2. Spatial and temporal patterns of in situ denitrification were …

Analysis of the periodically fragmented environment model: I–species persistence

H Berestycki, F Hamel, L Roques - Journal of Mathematical Biology, 2005 - Springer
… In the case of a bounded smooth domain, this definition reduces to the classical first
eigenvalue of L with Dirichlet boundary conditions (see [11], [42]). In the periodic case in RN , one …

Fast propagation for KPP equations with slowly decaying initial conditions

F Hamel, L Roques - Journal of Differential Equations, 2010 - Elsevier
This paper is devoted to the analysis of the large-time behavior of solutions of one-dimensional
Fisher–KPP reaction–diffusion equations. The initial conditions are assumed to be …

Uniqueness and stability properties of monostable pulsating fronts

F Hamel, L Roques - Journal of the European Mathematical Society, 2010 - ems.press
We prove the uniqueness, up to shifts, of pulsating traveling fronts for reaction-diffusion
equations in periodic media with Kolmogorov–Petrovskiĭ–Piskunov type nonlinearities. These …
