Surface hydration‐induced damage in tight oil‐bearing sandy conglomerate reservoirs

open access: yesDeep Underground Science and Engineering, EarlyView.
A series of techniques such as X‐ray diffraction, scanning electron microscopy, energy‐dispersive spectroscopy, conductivity tests, and infrared thermal imaging were used. The key findings are the identification of a two‐stage surface hydration process and the elucidation of the effects of various minerals and elements on the hydration process ...

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Responses of Antarctic seabird populations to past climate change

open access: yesEcography, EarlyView.
Higher‐order predators such as Antarctic seabirds serve as ecological indicators of environmental change and provide a crucial trophic link between marine and terrestrial ecosystems. Despite their prevalence and significance in the Antarctic ecosystem, there is a lack of understanding of the impacts of major regime shifts in paleoclimate on flighted ...

Rising, falling, stalling: complex biodiversity trajectories in English rivers

open access: yesEcography, EarlyView.
Freshwater ecosystems face intense anthropogenic pressures. Yet in parts of Europe, including the UK, studies have documented widespread increases in macroinvertebrate diversity following investments to improve water quality. More recent analyses, however, suggest that these gains have slowed, plateaued, or even reversed. Despite increasing recognition

Soil Carbon Markets in the Making: Power Relations and Matters of Concern in Offsetting and Insetting

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT This paper investigates emerging soil carbon markets and seeks to identify the groups of actors and power relations that constitute their structure and function. Voluntary soil carbon markets (VSCMs) are emerging globally as a key mechanism for generating carbon removals as part of climate mitigation efforts.

Development of a Zebrafish Embryo‐Based Test System for Thyroid Hormone System Disruption: 3Rs in Ecotoxicological Research

open access: yesEnvironmental Toxicology and Chemistry, EarlyView.
Abstract There is increasing concern regarding pollutants disrupting the vertebrate thyroid hormone (TH) system, which is crucial for development. Thus, identification of TH system–disrupting chemicals (THSDCs) is an important requirement in the Organisation for Economic Co‐operation and Development (OECD) testing framework.
