Acid‐activated water hyacinth (Eichhornia crassipes) from the Nile River for textile wastewater reclamation: A comparative evaluation of anionic and cationic dye adsorption

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Water hyacinth (Eichhornia crassipes) is an extremely invasive aquatic plant with notable environmental and socioeconomic impacts; however, its unique physicochemical properties offer potential for wastewater treatment through adsorption. This study investigates the acid activation of water hyacinth using acetic, sulphuric, hydrochloric, and ...

Greenhushing as Strategic Adaptation: Net‐Zero Commitment Retreat Among S&P 500 Firms Amid Environmental, Social, and Governance (ESG) Backlash

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Greenhushing has emerged as a strategic corporate response to political and regulatory uncertainty, yet less is known about how firms recalibrate previously established sustainability signals when external conditions change. Drawing on signaling theory, this study examines changes in corporate climate and ESG commitments during the political ...

Perceptions of Governance (Il)Legitimacy Mediate Climate Change Adaptation in the Lake Victoria Basin, Uganda

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Governance is a well‐known dimension of adaptive capacity across various frameworks, however specific links between perceptions of governance (il)legitimacy and adaptive capacity remain relatively unexplored. In this study, we investigate connections between climate change adaptation and perceptions of governance (il)legitimacy using focus ...

Historical shifts in Brazilian P. falciparum population structure and drug resistance alleles. [PDF]

open access: yesPLoS ONE, 2013
Previous work suggests that Brazilian Plasmodium falciparum has limited genetic diversity and a history of bottlenecks, multiple reintroductions due to human migration, and clonal expansions. We hypothesized that Brazilian P.

Primary modes of tree mortality in southwestern Amazon forests

open access: yesTrees, Forests and People, 2022
Tree mortality rates and the modes of tree death have recently been extensively investigated in the Amazon. However, efforts to describe these processes have not been well distributed across the basin.

Transformative, Iterative or Performative? Conceptualising Patterns of Fossil Fuel Phaseout Leadership

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Global leadership in phasing out fossil fuels is an important new frontier in climate governance, yet remains undertheorised within existing scholarly accounts of climate leadership. In this paper, we argue that ‘phaseout leadership’—climate leadership centred on curtailing fossil fuel supply—is a distinct kind of leadership that dominant ...

The Western Amazonian Richness Gradient for Squamate Reptiles: Are There Really Fewer Snakes and Lizards in Southwestern Amazonian Lowlands?

open access: yesDiversity, 2019
The lowland rainforests of the Amazon basin harbor some of the most species-rich reptile communities on Earth. However, there is considerable heterogeneity among climatically-similar sites across the Amazon basin, and faunal surveys for southwestern ...

Unlocking Hydrokinetic Energy in the Brazilian Amazon: A Statistical Resource Assessment and Economic Feasibility Analysis

open access: yesEnergy Science &Engineering, EarlyView.
This study develops a spatial and technical framework to evaluate hydrokinetic energy potential in the Amazon as a sustainable alternative to diesel‐based systems. By modeling regional resources, we demonstrate that hydrokinetic sources offer a cleaner, economically competitive solution for displacing fossil fuels in remote riverine communities ...
