Amazonia 2040: Spatial‐explicit futures scenarios for the mosaic of protected areas in the Lower Rio Negro (MBRN), Brazil

Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
Spatial‐explicit futures scenarios were applied in the Mosaic of Protected Areas of the Lower Rio Negro (MBRN), for co‐creating scenarios for the MBRN in the year 2040. Scenario making enabled negotiating desirable futures, aligning values and goals.

Stochastic Modelling of Daily Precipitation in Semi‐Arid Regions Using Markov Chains and Parametric Distributions

International Journal of Climatology, Volume 46, Issue 4, 30 March 2026.
This study applies stochastic rainfall models combining Markov Chains with gamma and mixed exponential distributions to a semi‐arid climate in Northeast Brazil. Model structures were evaluated using Bayesian Information Criterion (BIC), with maximum likelihood (MLM) for parameter estimation and cumulative distribution functions (CDFs) for validation ...

Critical Slowing Down Reveals Hydrologic Resilience Loss Across Amazon Sub‐Basins

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract The Amazon's hydroclimate exhibits basin‐scale early‐warning signals of critical slowing down (CSD), a statistical signature of declining resilience as systems approach critical transitions. We apply a multi‐metric framework to precipitation, evapotranspiration, Soil moisture (SM), and extreme streamflows, tracking rolling variance, lag‐1 ...

Streamflow Elasticity to Precipitation Distribution and Potential Evapotranspiration Across South America

Hydrological Processes, Volume 40, Issue 2, February 2026.
Graphical abstract summarizing the modelling experiments used to quantify streamflow elasticity to changes and temporal redistribution of precipitation across South America, highlighting stronger effects of seasonal redistribution and larger responses in humid climates. ABSTRACT This study examines the sensitivity of mean, high and low streamflows (i.e.

Between Droughts and Floods: The Seasonal Response of Freshwater Snails in Artificial Reservoirs in the Brazilian Semiarid Region

Population Ecology, Volume 68, Issue 1, January 2026.
We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year,

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,

The economic displacement of thousands of fishers in the Pantanal, Brazil: A telling story of small‐scale fisheries marginalization worldwide.

Fish and Fisheries, Volume 25, Issue 6, Page 951-958, November 2024.
Abstract A new policy in the Pantanal wetland, Brazil, aims to economically displace thousands of artisanal fishers from one‐third of the region. The legislation disregards several FAO Voluntary Guidelines for Securing Sustainability in Small‐Scale Fisheries' guiding principles (SSF guidelines). Considering that 2024 marks the 10th anniversary of these
