Description of the subject. The geographic distributions of a species, be it native or alien, is expected to be limited at some point by environmental conditions. In this situation, a range edge equilibrium (REE) takes place, i.e., populations occurring beyond the edge have a growth rate reduced...

Objective: To compare the sediment characteristics under exotic mangrove species (Sonneratia apetala, Laguncularia racemosa) and native mangrove species (Aegiceras corniculatum, Acrostichum aureum), so as to better understand the potential ecological impacts of exotic species on the wetland...
