Dissolved load, chemical weathering, and CO2 uptake dynamics of small tropical mountainous rivers of Southern Granulite Terrain, Karamana and Vamanpuram, Western Ghats, India

Scientific Reports
Chemical weathering in a river basin is a key geochemical process that controls fluxes between the atmosphere, land, and ocean, playing a crucial role in regulating Earth’s climate, particularly the small tropical mountainous rivers with high weathering ...

Weathering-Induced Strength Degradation and Hydro-Mechanical Controls on the Stability of Multilayered Tropical Rock Slopes

Journal of the Civil Engineering Forum
Tropical environments accelerate rock weathering, which can significantly reduce the stability of mineralized slopes. This study investigates the influence of weathering and groundwater conditions on the stability of a strong–weak–strong multilayered ...

Contrasted Chemical Weathering Rates in Cratonic Basins: The Ogooué and Mbei Rivers, Western Central Africa

Frontiers in Water, 2021
Despite the absence of tectonic activity, cratonic environments are characterized by strongly variable, and in places significant, rock weathering rates. This is shown here through an exploration of the weathering rates in two inter-tropical river basins

Vegetation controls on weathering intensity during the last deglacial transition in southeast Africa.

PLoS ONE, 2014
Tropical climate is rapidly changing, but the effects of these changes on the geosphere are unknown, despite a likelihood of climatically-induced changes on weathering and erosion.

How Does Patient Capital Enhance Agribusiness Resilience? Evidence From Chinese Listed Agribusinesses

Agribusiness, EarlyView.
ABSTRACT In emerging economies where smallholder farming dominates agricultural production, agribusinesses serve as critical intermediaries linking smallholders to broader markets, and their resilience directly affects agricultural sustainability. Short‐term‐oriented capital is reluctant to adequately finance highly uncertain and cyclical agricultural ...

Study of an abnormal occurrence of Oxisols in strongly undulated relief in the south of Minas Gerais, Brazil, with support of pXRF and geomorphology

Ciência e Agrotecnologia, 2021
Oxisols are the main soils in Brazil and they classically occur in stable and gentle geomorphic surfaces. However, in the south of Minas Gerais State, Oxisols have been observed under strongly undulated relief, a very rare condition for these soils in ...

Intensified Manufactured Non‐Belonging: Working Holiday Makers in Australia During the COVID‐19 Pandemic

Australian Journal of Social Issues, EarlyView.
ABSTRACT Nations manufacture non‐belonging of temporary migrants through policy frameworks that produce exclusion. This precarity maximises the economic benefit of temporary migrant labour by minimising their political, social and legal rights. In this paper, we examine how non‐belonging targeting Working Holiday Makers (WHMs) is manufactured in ...

Iron Isotopes Reveal Fe Export Driven by Change of Tropical Weathering Regime

Geophysical Research Letters
Unraveling paleoenvironmental signals recorded in laterites is crucial for quantifying weathering‐driven elemental fluxes at the Earth's surface. New stable iron isotope data (δ56Fe), combined with (U‐Th)/He ages in Fe‐oxides from a ferruginous duricrust

Herbarium‐based measurements are reliable predictors of fresh plant traits in Neotropical Myrtaceae

Applications in Plant Sciences, EarlyView.
Abstract Premise Herbarium specimens are increasingly used to extract morphological traits for ecological and evolutionary studies, yet the effects of tissue desiccation on trait measurements remain poorly understood. Here, we tested two hypotheses: (H1) whether higher tissue water content leads to greater measurement changes after herborization and ...

The contribution of weathering of the main Alpine rivers on the global carbon cycle [PDF]

, 2013
On geological time-scales the carbon fluxes from the solid Earth to the atmosphere mainly result from volcanism and metamorphic-decarbonation processes, whereas the carbon fluxes from atmosphere to solid Earth mainly depend on weathering of silicates and
