research activities in the group divide into two main categories:
- Nonlinear dynamics and pattern
formation, where the emphasis is mostly on universal phenomena not
specific to any particular system.
- Nonlinear physics of ecosystems, where
part of the effort is devoted to modeling. Special emphasis is given to
understanding biodiversity and desertification phenomena
in water limited ecosystems.
projects in progress:
Nonlinear dynamics and pattern formation
- Pattern formation and wavenumber-locking
in spatially forced systems.
- Pattern formation in anisotropic media
(catalytic surface reactions, vegetation bands on slopes).
Nonlinear physics of ecosystems
- Vegetation patterns in water limited systems, periodic
vs. scale-free patterns, applications to desertification and rehabilitation. Click here for an
animation of vegetation patterns along a rainfall gradient.
- Plants as ecosystem engineers,
interspecific interactions and transitions from competition to
facilitation, applications to biodiversity.
