Achieving conservation through cattle ranching: The case of the Brazilian Pantanal

open access: yesConservation Science and Practice, Volume 7, Issue 7, July 2025.
Cattle ranching in the Pantanal should be part of the conservation agenda and we show the pathways to it. Abstract Cattle ranching in the ~140,000 km2 Brazilian Pantanal is considered one of the most important cases of sustainable use of natural resources in the global south. The region has had a successful history of balancing environmental protection

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

open access: yesConservation 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,
