Numerical prediction of the optimal shield tunneling strategy for tunnel construction in karst regions.

PLoS ONE, 2021
Shield tunneling in karst areas poses significant challenges, as vibration caused by the shield machine can disturb the stability of the karst caves, ultimately resulting in the collapse of a tunnel.

From Trapped to Resilient Mountains: Diversified Coupling Pathways Linking Land Use Transition and Rural Revitalization for Mountain Sustainable Development

Land Degradation &Development, EarlyView.
ABSTRACT The synergistic interplay among land use transition, rural revitalization, and sustainable development is critical for harmonizing human‐land‐economic systems. Understanding their diverse coupling pathways is key to resolving human‐land conflicts and advancing sustainable rural development in mountainous regions. However, existing research has

Non-anthropogenic sources of carbon dioxide in the Glowworm Cave, Waitomo [PDF]

, 2009
The Waitomo Caves attract approximately 500 000 tourists each year. A requirement of tourist cave management is that the partial pressure of carbon dioxide (PCO₂) is kept below levels that are: hazardous to the health of visitors, hazardous to the ...

Stability analysis of karst tunnel surrounding rock considering spatiotemporal effects

Carsologica Sinica
During tunnel construction, various geological problems may be encountered, and karst development can cause great harm to the tunnel. Because the lithology of the rock mass in the karst area is poor and its structure is relatively broken, it is likely to

Needle in a haystack: Holocene history of European larch in Central Europe revisited

PLANTS, PEOPLE, PLANET, EarlyView.
Defining nativity of species is crucial for their management. However, this is a complex task, especially for species that have been used and spread by humans for a long time. We combined paleoecological records with extensive genetic data to investigate the Holocene history of European larch—a common and economically important tree species in Central ...

Cave and karst development in the Craven Basin, UK [PDF]

, 2015
The Craven Basin, which was an area of crustal subsidence during much of the Carboniferous, contains carbonate strata that pre-date the deposition of the better known carbonates of the Askrigg Block to the north.

Determinants of Community Resilience: A Multi‐Level Synthesis of Empirical and Conceptual Evidence

Sustainable Development, EarlyView.
ABSTRACT Community resilience research remains fragmented across disciplines, with limited integration of empirical evidence and conceptual scholarship. This study addresses this gap through a directed content analysis of 48 empirical case studies and 39 conceptual and review publications from diverse geographical and hazard contexts.

The emergence and complexification of symbolic practices in the Homo lineage: an archaeological and cognitive perspective Émergence et complexification des pratiques symboliques dans la lignée Homo : une approche archéologique et cognitive

Journal of the Royal Anthropological Institute, EarlyView.
Recent archaeological discoveries, reviewed in this essay, challenge traditional views on the emergence of human symbolic cognition. Once believed to have originated in Europe around 40,000 years ago, new evidence shows it emerged much earlier across diverse regions.
