Patch organization and resilience of dryland wetlands
Dryland wetlands are ecosystems of high ecological importance as they serve as habitat sanctuaries for aquatic and terrestrial biota in areas with very few resources; therefore, the study of such environments is of major importance for the conservation of biodiversity in arid and semi-arid areas....

| description |
Dryland wetlands are ecosystems of high ecological importance as they serve as habitat sanctuaries for aquatic
and terrestrial biota in areas with very few resources; therefore, the study of such environments is of major importance
for the conservation of biodiversity in arid and semi-arid areas. The vegetation organization in these
ecosystems is driven by the water regime as the main driver, but local processes like seed banks and soil resources
redistribution also play a crucial role in determining the spatial distribution of the vegetation. Assessment
of vegetation dynamics and long-termresilience requires the use of realistic models that can integrate the water
regimeand that can continuously simulate vegetation extent and conditions under flood-drought cycles. Herewe
study the influence of the water regime as the main driver of the vegetation. We apply a vegetation-modelling
framework to compare the performance of a simplified model at the cell scale and a model integrated at a
patch scale. Our results show that aggregating the analysis of vegetation dynamics at the patch scale allows for
the incorporation of the effects of both local drivers (acting within the patch) aswell as the global drivers (acting
over the patch as a whole). The water regime acts as a global driver for the vegetation and indirectly affects the
local drivers. Our patch scalemodel successfully captures wetland vegetation dynamics using thewater regimeas
the main driver for representing changes in the vegetation and assessment of thewetland resilience under flooddrought
periods. |
