Contestation Between the State, Oil and Fishers in Trinidad and Tobago: (Re)producing ‘Edge’ Populations on the Post‐Plantation Extraction Frontier

Journal of Agrarian Change, EarlyView.
ABSTRACT Successive waves of extraction in the Caribbean—from plantation monocultures to oil and gas—have reshaped overlapping agrarian, coastal and marine environments, undermining the socio‐ecological foundations of small‐scale fisher livelihoods and generating ongoing conflict between the state, energy sector and fishing communities. Yet despite the

Impact of bauxite mining on mosquito communities (Diptera: Culicidae) and pathogen transmission risks in the eastern Amazon

Medical and Veterinary Entomology, EarlyView.
Bauxite mining in the Amazon alters mosquito communities, favouring anthropophilic and generalist vectors while reducing species diversity and the variety of blood meal sources. Molecular analyses identified humans, tapirs and deer as the primary blood meal sources.

Evolution of ecological indicators in the assessment of restoration of mining‐degraded riparian forests: a global bibliometric analysis (1990–2024)

Restoration Ecology, EarlyView.
Abstract Introduction The restoration of mining‐degraded riparian forests faces challenges due to structural, compositional, and functional impacts on these ecosystems. The demand for effective monitoring requires an understanding of how ecological indicators have been applied to assess post‐mining restoration success.

Refractory Metakaolin Geopolymers: Achieving High Mechanical Strength and Near‐Zero Shrinkage After Exposure to 800°C

Journal of the American Ceramic Society, Volume 109, Issue 11, November 2026.
ABSTRACT Metakaolin‐based geopolymers are candidate binders for refractory and fire‐resistant components because they combine ceramic‐like thermal stability with low‐temperature processing. Their use is still restricted by a trade‐off: Formulations that develop high strength shrink substantially near 800°C, while formulations that remain dimensionally ...

Quantifying Natural Hydrogen‐Helium Sources and Dynamic Accumulation in Global Sedimentary Basins

Earth's Future, Volume 14, Issue 10, October 2026.
Abstract Despite the scientific and economic importance of hydrogen and helium, their crustal budgets remain poorly quantified. This study systematically assesses the accumulation of natural hydrogen and helium in global sedimentary basins by integrating predictive models for both gases with H2/He ratios.
