  abstract = {{M}ud bank colonization by mangroves on the {A}mazon-influenced coast of {F}rench {G}uiana was studied using light detection and ranging (lidar) data which provide unique information on canopy geometry an sub-canopy topography. {T}he role of topography was assessed through analysis of vegetation characteristics derived from these data. {M}easurements and analyses of mangrove expansion rates over space and time led to the identification of two distinct colonization processes. {T}he first involves regular step-by-step mangrove expansion to the northwest of the experimental site. {T}he second is qualified as 'opportunistic' since it involves a clear relationship between specific ecological characteristics of pioneer {A}vicennia and mud cracks affecting the mud bank surface and for which probabilities of occurrence were computed from terrain elevations. {I}t is argued from an original analysis of the latter relationship that mud cracks cannot be solely viewed as water stress features that reflect desiccation potentially harmful to plant growth. {I}ndeed, our results tend to demonstrate that they significantly enhance the propensity for mangroves to anchor and take root, thus leading to the colonization of tens of hectares in a few days. {T}he limits and potential of lidar data are discussed with reference to the study of muddy coasts. {F}inally, the findings of the study are reconsidered within the context of a better understanding of both topography and vegetation characteristics on mangrove-fringed muddy coasts.},
