Ecotoxicological Assessment of Mercury in Fish From a Gold‐Mining‐Impacted Amazonian River: Biomonitoring and Human Health Risk

Environmental Toxicology, EarlyView.
ABSTRACT The Peixoto de Azevedo River, located in northern Mato Grosso, southern Brazilian Amazon, has a long history of artisanal and small‐scale gold mining (ASGM). This study evaluated total mercury (THg) concentrations in fish tissues to assess biomagnification and potential risks.

Climate‐Modulated Particle Toxicity: Acute Exposure to an Environmentally Informed Microplastic Mixture Induces Sex‐Dependent Systemic Reorganization in Swiss Mice

Environmental Toxicology, EarlyView.
ABSTRACT Microplastic (MP) pollution is widely recognized as an emerging environmental threat. Yet, most studies still rely on controlled experimental conditions that poorly reflect environmental complexity, potentially underestimating risks under realistic scenarios, particularly during short‐term exposures. Here, we tested whether acute oral exposure

Optimising daily sampling of plant–bee interaction networks

Journal of Animal Ecology, EarlyView.
Daily variation in ecological interaction networks is rarely quantified due to limited temporal sampling, yet network structure may change substantially within a single day. We show that plant–bee networks exhibit strong intraday shifts in composition and structure, and that sampling distributed across key daily periods better captures network ...

Bat community assembly in the ecotone of two neotropical biodiversity hotspots is determined by environmental filtering rather than historical factors

Journal of Animal Ecology, EarlyView.
We demonstrate that environmental filtering is the primary mechanism shaping bat communities across the Cerrado–Atlantic Forest ecotone. By integrating phylogenetic diversity, environmental gradients, and coevolutionary assembly models, our study provides new insights into the processes maintaining biodiversity in a globally important transition zone ...

The Economic and Ecological Impact of Soy in Brazil: A Synthetic Control Method Approach

Journal of Agricultural Economics, EarlyView.
ABSTRACT In recent decades, soy expansion in Brazil has generated significant environmental, social and economic impacts. However, there is no consensus about benefits and drawbacks, calling for a more careful account of the economic and ecological diversity of the territories where this phenomenon has been unfolding.

Aligning Transnational due Diligence: The EU Deforestation Regulation and Brazil's Fragmented Beef Governance

Global Policy, EarlyView.
ABSTRACT Transnational due diligence regulations, such as the European Union Regulation on Deforestation‐Free Products (EUDR), are reshaping sustainability governance by transforming voluntary norms into binding global rules. Yet, their effectiveness depends on how well they align with domestic governance systems and on the power asymmetries that ...
