A minimalistic model of vegetation physiognomies in the savanna biome

Yatat Djeumen, Ivric Valaire; Dumont, Yves; Doizy, A.; Couteron, P. (Elsevier, 2021-01)

We present and analyze a model aiming at recovering, as dynamical outcomes of fire-mediated tree–grass interactions, the wide range of vegetation physiognomies observable in the savanna biome along rainfall gradients at ...
Spreading speeds and traveling waves for monotone systems of impulsive reaction–diffusion equations : application to tree–grass interactions in fire-prone savannas

Banasiak, Jacek; Dumont, Yves; Yatat Djeumen, Ivric Valaire (Springer, 2023-07)

Many systems in life sciences have been modeled by reaction–diffusion equations. However, under some circumstances, these biological systems may experience instantaneous and periodic perturbations (e.g. harvest, birth, ...
