When Norms Meet Markets: Environmental Governance and Digital Fast‐Fashion Platforms in Brazil

Sustainable Development, EarlyView.
ABSTRACT Environmental governance increasingly relies on consumer‐based mechanisms that assume that sustainability awareness translates into purchasing behaviour. This article investigates whether such mechanisms remain effective when consumption is organised through transnational digital platforms in contexts characterised by socioeconomic inequality.

Gross Agricultural Emissions and Unequal Mitigation Pathways in the Brazilian Legal Amazon: Implications for Climate Justice and the Sustainable Development Goals

Sustainable Development, EarlyView.
ABSTRACT Climate mitigation policies in the Brazilian Legal Amazon have largely focused on aggregate or net emissions, providing limited evidence on how gross agricultural emissions reveal the intensity of productive emission sources independently of carbon removals.

Cyanogenic Compounds, Physicochemical Parameters and Metals in Water From Cassava Processing Areas: A Study in the Brazilian Amazon, Using Multivariate Analysis

Environmental Toxicology, EarlyView.
ABSTRACT This study evaluated the water quality of artesian wells and effluents generated in cassava processing in a rural area of Bragança, Pará, with emphasis on physicochemical parameters, multielement composition, and cyanogenic compounds. The well water presented specific nonconformities, highlighting pH values below the recommended level and high

Oxidative Stress Biomarkers in the Shrimp Macrobrachium amazonicum (Heller, 1862): Assessment in an Environmental Preservation Area in the Brazilian Amazon

Environmental Toxicology, EarlyView.
ABSTRACT Anthropogenic activities generate a significant amount of pollutants that are released into the environment, causing physiological and ecological disturbances. Among the xenobiotics present in aquatic ecosystems, numerous chemical and organic compounds have oxidative potential or are metabolized through oxidative processes, which may amplify ...

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.

Jaguar Densities and Land Cover Change in a Multi‐Use Landscape: A 10‐Year Comparison in the Colombian Llanos 美洲豹种群密度与复合用地景观下的土地覆被变化:哥伦比亚亚诺斯地区10年比较研究

Wildlife Letters, EarlyView.
We used spatially explicit capture‐recapture to estimate jaguar densities in a private reserve in the Colombian Llanos and quantified land cover change in and around the reserve from 2014 to 2024. Densities increased 22% since 2014, while disturbed land cover increased by 39%–54% around the reserve depending on buffer distance. Our study indicates that

Availability of a Keystone Plant Resource Reduces Niche Overlap and Drives Distinct Species‐Specific Changes in Niche Breadth Among Small Rodents

Integrative Zoology, EarlyView.
We investigated how three rodent species respond to the seasonal availability of Araucaria angustifolia seeds. While Oligoryzomys spp. increased seed consumption and abundance during seed production, the more insectivorous Akodon paranaensis maintained a broader diet.
