Fish distribution across altitudinal gradients in the Upper Paraguay River Basin: Implications for conservation in the Pantanal region

Conservation Science and Practice, Volume 7, Issue 7, July 2025.
This paper approaches the patterns in fish distribution across the altitudinal gradient in the Upper Paraguay River basin, from uplands to the floodplain. We compiled more than 75,000 available fish records and registered 342 fish species and your distribution along altitudinal gradient. Floodplain portion have higher species diversity than headwaters,
