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

Mostrar todas las versiones(2)

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...

Bena, María Julia Sirolli, Horacio Kalesnik, Fabio Río Uruguay endicamiento pastoreo comunidades herbáceas bajos inundables. Uruguay river dyking grazing herbaceous communities floodable lowlands. 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 lowlands of two farms, one of which is surrounded by an embankment to prevent flooding. A random stratified sampling was performed in 72 plots. To detect distribution patterns and plant species associations we performed a Detrended Correspondence Analysis (DCA) and a Two-Way indicator species analysis (TWINSPAN). We could identify six groups of plots whose ordination patterns are related to the flooding preferences of dominant species. Herbaceous plant groups that develop in anthropically modified environments showed the highest overall richness and diversity with the ingression of invasive species but, they formed a homogeneous patch at a landscape scale. Plant associations with minor anthropic modifications showed lower richness and diversity values but, from a floristic point of view, they formed a heterogeneous mosaic. Impacto de las actividades agropecuarias sobre humedales de planicies inundables: el caso del río Uruguay. A pesar de ser ambientes valiosos, los humedales sufren procesos de explotacióny transformación intensivos que afectan su biodiversidad. El objetivo principal de este trabajo fue caracterizar las comunidades herbáceas asociadas a la porción sur de la planicie de inundación del ríoUruguay. Para ello, nos concentramos en las zonas bajas de dos establecimientos agropecuarios, uno de los cuales se encuentra rodeado por un endicamiento que evita las inundaciones. Se llevó a cabo un muestreo estratificado al azar en 72 parcelas. Para detectar patrones de ordenamiento y asociaciones de especies, realizamos un análisis de correspondencia destendenciado (DCA) y un análisis de especies indicadoras de doble via (TWINSPAN). Pudimos identificar seis asociaciones de especies cuyos patrones de ordenamiento están relacionados con las preferencias de inundación de las especies dominantes. Los grupos de plantas herbáceas que se desarrollan en ambientes antrópicamente modificados presentan una mayor riqueza y diversidad con el ingreso de especies exóticas, aunque formando un parche homogéneno a escala de paisaje. Mientras que, las  asociaciones de plantas con escasas modificaciones muestran valores de riqueza y diversidad menores, pero desde el punto de vista florístico, forman un mosaico heterogéneo de ambientes.
