  abstract = {{N}early 15,000 shallow, saline or freshwater lakes and ponds coexist in close proximity in the {N}hecolandia, a 24,000 km(2) subregion of the {P}antanal wetland in {B}razil. {T}his study aims to understand the origin of such diversity in surface water, which is a key aspect for the wetland services and biodiversity in the region. {B}oth soil observations and water samples were collected at the regional or local scale and supplemented by previously published data sets. {S}tatistical and geostatistical treatments were carried out and completed by discrete water-table monitoring. {T}he results confirmed the absence of a regional pattern in surface-water salinity, and the independence of electrical conductivity values, even for neighboring lakes. {D}espite great differences in chemical composition, all surface waters in the region belong to the same chemical family, corresponding to several concentration stages of the {T}aquari {R}iver water that supplies the region. {T}he concentration stage depends on the hydrological functioning of each lake, which is itself controlled by the relative importance of low-permeability soils as a barrier to movement of water into or out of the lakes through the subsurface. {I}n this framework, oligosaline ponds, freshwater lakes, and saline lakes work as recharge, flow-through, and discharge wetlands, respectively. {T}he salinity observed in some lakes results from an ongoing process of accumulation and evaporation under relatively humid climatic conditions and poor drainage.},
