abstract = "Remote sensing studies of vegetation cover and hydrologic dynamics
in Amazonian wetlands have been mostly limited temporally or
spatially, and the distribution and spatial configuration of
Amazonian va´rzea habitats remains poorly known. This study uses
multitemporal PALSAR L-band radar imagery combined with
object-based image analysis, data mining techniques and field data
to derive vegetation structure and inundation patterns and
characterize major vegetation types in va´rzea forests of the
Mamirau{\'a} Sustainable Development Reserve. Our results show
that the combination of vegetation cover and inundation extent
information can be a good indicator of the complex gradient of
habitats along the floodplain. The intersection between vegetation
and flood duration classes showed a wider range of combinations
than suggested from field based studies. Chavascal areas
chacaracterized as a dense and species-poor shrub/tree community
developing in old depressions, abandoned channels, and shallow
lakes had shorter inundation periods than the usually recognized
hydroperiod of 180240 days of flooding, while low v{\'a}rzea a
diverse community that have fewest and smallest species, and
highest individual density and that tolerate 120180 days of
flooding every year was distributed between flood duration ranges
that were higher than reported by the literature. Forest
communities growing at sites that were never mapped as flooded
could indicate areas that only flood during extreme hydrological
events, for short periods of time. Our results emphasize the
potential contribution of SAR remote sensing to the monitoring and
management of wetland environments, providing not only accurate
information on spatial landscape configuration and vegetation
distribution, but also important insights on the ecohydrological
processes that ultimately determine the distribution of complex
floodplain habitat mosaics.",
