Agriculture and livestock impacts on river floodplain wetlands: A study case from the lower Uruguay river

Even though wetlands are very valuable environments, they suffer heavy exploitation and transformation processes that affect their biodiversity. The main goal of this study was to characterize the herbaceous plant communities associated with the southern Uruguay River flood plain. We focused on lowl...
