Seasonal Variation in Carbon Dynamics in the Lower Tocantins River: Influence of Discharge and Environmental Drivers

River Research and Applications, EarlyView.
ABSTRACT Tropical rivers play a key role in regional carbon budgets, yet greenhouse gas (GHG) dynamics in regulated systems remain poorly understood. This study investigates the seasonal variability of carbon dioxide (CO2) and methane (CH4) concentrations, isotopic composition (δ13C), and river‐atmosphere fluxes in the lower Tocantins River, a ...

Impact of the Addition of a Shading Algorithm in a Physically Based Conceptual River Hydrological–Temperature Model

River Research and Applications, EarlyView.
ABSTRACT Anthropogenic impacts on the thermal regime of rivers include climate change and deforestation. For the latter, developing modelling tools that can account for the impact of varying vegetation cover on river temperatures is essential. This study describes a new addition to the CEQUEAU hydrological and water temperature model: a shading ...

Improved Cerrado Wetland Mapping Through Seasonal Moisture Metrics, Terrain Information and Semantic Segmentation

Remote Sensing in Ecology and Conservation, EarlyView.
Brazil's Cerrado valley wetlands—swamp savanna and gallery forest—are highly important for the biome's water cycle and carbon storage and are susceptible to degradation from the impacts of land use expansion and the climate crisis. In support of their detailed monitoring and assessment, we developed and tested a transferable mapping approach that ...

Continuous field assessments and data sharing to rationalize the IUCN's impact in mammal conservation: a case study of Rwanda

Wildlife Biology, EarlyView.
Taxonomic work, conservation practice, and Red List assessments from the International Union for Conservation of Nature (IUCN) are intricately linked. The primary conservation goal for biodiversity is to halt the factors driving local extinctions of species.

Biological invasions disrupt the relationship between size spectrum and trophic interactions in freshwater fish communities

Journal of Animal Ecology, EarlyView.
Our study shows that non‐native species alter the relationship between the size‐spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic niches. Abstract The size spectrum, which describes the relationship between abundance (or biomass) and body size, is an ataxic approach that can provide ...

Cuttings, Combings, Fettlings and Flock: Gender and Australian Wool ‘Waste’, 1900–1950

Gender &History, EarlyView.
ABSTRACT As Australia's wool industry produced vast amounts of fine fleece from the nineteenth century, the wool processing and clothes manufacturing industries generated waste – products like cuttings, combings, fettlings and flock. Salvaged and then sold to waste merchants, these and other materials had a second life.

Accommodating Women: Geographies of Citizenship in the Twentieth‐Century Campaign for Women's Jury Rights

Gender &History, EarlyView.
ABSTRACT Australian women were among the first in the world to receive electoral suffrage, yet it took until 1997 before they had full equality of jury suffrage. This article examines the debate around female jurors by focusing less on discourses of citizenship than on the subterranean spatial arrangements upon which equality depended.

‘Sinister Indian‐like Half‐circle’: Tennis, Orientalism and the White Racial Frame in the Twentieth‐Century British Sporting Press

History, EarlyView.
Abstract Examining sport alongside race, media and imperial power opens a rich field for understanding how macro‐level ideologies are shaped and circulated through everyday cultural forms. In twentieth‐century Britain, mass media framed and distributed narratives that rendered the empire's political realities intelligible to a broad public.
